听力演讲1

In last weeks lecture, we discussed reasons whypeople forget things. This week we will discuss asurprising reason why we might remember somethings, anxiety. Think about something as simple asbuying a coffee. That may not seem like an experience that would make a deep impression onyour memory. But anxiety could change that. fact, a new study suggests that people withhigher anxiety levels might remembertertain information better than people with lower anxietylevels.

Thats because higher levels of anxiety may makepeople moresusceptible to negative feelings,

putting them in a more negative state of mind. Thatin turn, may make them able to better remembersome events. Lets take a closer look at that newstudy now. Q17. In this study, tseardhersstarted by giving 80 undergraduate students ananxiety test. The test measure the participantsanxiety levels over the proceeding two weeks.

Then, to test memory, the participants were showna series of neutral words one at a time. Some of thewords were printed onto photos of negative scenes,meaning images that could affect their emotionsnegatively, such as a photo of a car accident, or acemetery. The rest of the words were printed ontophotos of neutral scenes, such as a photo of a lakeor trees. Neutral words included words like table ordesk that dont elicit emotion.

Later, the participants were asked to think back tothe words they were shown earlier, which causedthem to reenter either a negative or neutral mindset. The participants were then presented withanother set of neutral words, and their memory ofthese new words was tested.

The researchers found that the new words presented to people in a negative mindset werebetter remembered by people with higher levels ofanxiety than those with lower levels of anxiety.

In other words, when highly anxious individualstook in otherwise emotionally neutral informationthat was presented to them, it became colored bytheir negative mindset, making them remember theinformation better. But these same effects were notseen in people with low levels of anxiety.

Q18. Previous studies havefound that extremeevels of anxiety such as those experienced bypeople diagnosed with an anxiety disorder can bequite detrimentalto memory and cognitive performan But the highly anxious people in thisstudy represent individuals who are managing theiranxiety and for whom anxiety is not. a seriousproblem.

Question 16. What does the speaker say the newstudy suggests?

Question 17. What did researchers do first in thenew study?

Question 18. What do we learn from previousstudies aboutlanxiety?

Over the past 20 years, the u ternet hasgradually be a dominant featureof our lives. It has changed how wmunicate with each other. And ithas definitely transformed the way wedo business with each other:Marketinghas also changed in a number of ways.

For instance, in the past, consumershad to call a phone number and patiently wait on hold in order to getthe information they wanted.

[Q19]Today, they want the informationimmediately. Theyll go to thepanys sociaLmediapdc nifosments and questions expecting toreceive an immediate response. If theydont get their questions answeredsoon theyll move on to anothepany that will answer themquickly.

Marketing departments today need tofollow technological development. Forexample, this year smartphone issmarter than last years. s fariving cars are now on the road. Marketershave to do research on which techncingies:areing into bsing,otherwise, they risk being leit behindin the virtual dust.

Marketing has also changed due to theimportance of video. People dont justwant to read text. They walt to watchthings happening. Companies now have to explore how they can use videoon a consistent basis to share information about their , its extremely easy to

shoot something these days. All youneed is a smartphone.

But whats the result of all this? Shorteraitention spans? We arent the samepeople that we were 20 yedi ago. Notonly have we grown accustomed togetting the information we want instantaneously, our attention spansare much shorter. If something doesntcaptulc ourattention within a few

seconds. Were on to the next piece ofcontent.[Q20]Marketers need to figureout ways to speak directly to the customers emotions and they need tofigure out how to do that as quickly aspossible. Once people are emotionallyengaged, theyll stick with you.

If marketingi has changed this much inthe past 20 years, imagine what thenext 20 years will bring li ai recentsurvey, only 9% of marketers could saywith confidence that their marketingefforts were actually working. Theirconfidence is being shaken becausethe rules of the game change everyyear. Thats why [Q21]itsimportant for marketers to pay attention to the latest technological devel and consider collaborating with technological innovators. That way,theyll be moving at the same pace asthe tech industry.

Question 19 What does the speaker sayabout todays consumers?

Question 20 How do marketers captureconsumersattention as quickly aspossible?

Question 21 What does the speakersuggest marketers do to meet futurechalletes?

演讲3

You might be surprised to learn that [Q22] thebenefits offriendships extend beyond peoples

sociallifeand into their work, which is interestingwhen cd lili the extent to which people

sacrifice friendships, or at least the time they spendwith friends because of the exte edihairstheyredevoting to work. Just last week, rwas remarking toa colleague that Im content with only one socialengagement per week. But according to recentresearch, thats evidently not enough.

In an initial study of more than 700 respondents,scholars from an American university [Q23] analyzethe imrf thst:fiends as opposed to family haveon sel dem Jahd well-being. Friends came outsubstantially on top. Thats because to be someones mate is a voluntary act. Unlike familywho people rarely get to choose. The researchersfound that when people choose to cultivate andmaintain supportive friendships with an individual,it means that the person is valued and worthy oftheir limited time. Such sentiments of value andworthiness boost our self-esteem.

The second studyprised more than 300 participants. It proved that the better we feel aboutourselves, the more likely we will perform our jobconfidently andpetently. This follow-up studyfound that [Q24] non-work friends even improvedpeoples job satisfaction. They have as much of animpact on how much they love their jobs, as do thefriends they have at work, despite not actuallybeing at our place of work. These types of friendstend to be our preferred outlet fo nni aboutwork-related mattersyThis is an avenue that maynot be available at the office.

So even though friendships can be easy to neglectwhen confronted-by pressures at work, or evenpressures at home, neglecting our friends can turnout to be harmful and counterproductive. Thatswhy when determining how to create a better work-life balance, we need to consider not only how tobalance work and family demands, but also how tocultivate and sustain supportive friendships. Its for employees for flexible work arrangements. Its

irrelevant whether their need for a desired scheduleis due to say, parenting responsibilities, or a craving to hang out with their best mate. Whatmatters is the opportunity to engage in a nourishingactiyity outside of work. That will definitely have afollow-on effect at work.

Q 22 What does the speaker say is interesting?

Q 23 What did researchers from an Americanuniversity analyze in their initial study?

Q 24 What did the second study find aboutmon-work friends?

Q 25 What does the speaker suggest managers do?

Why we need tiny colleges

A)Were experiencing the rebirth of markets,tiny homes,and brew pubs all exemplify our love of do charter schools,coffee shops,and local is often(but not always)more affordable,healthier,and sustainable,but its finest characteristic,the one that turns charm into love,is that going small allows us to be more fully who we are.

B)In higher education the trend is mostly in the opposite direction:Universities with 20,000 or 30,000 students are considered“mid-sized”.The nations largest university,Arizona State University,has 80,000 students on campus and aims to enroll another 100,000 students the other end of the spectrum is a handful of colleges that have fewer than a hundred students on campus and no online courses:colleges such as Sterling College,Thomas More College of Liberal Arts,and Deep Springs colleges are so small that they can only be called “tiny.”

C)Tiny colleges focus not just on a young persons intellect,but on the young person as a important,tiny colleges ask,“How can education contribute to human flourishing and the well-being of the world?”And they shape a college experience to address that replace concerns about institutional growth with attention to the growth of students as fully developed participants in theirmunities.

D)Ive had the privilege of teaching at three different institutions of higher learning during my career—a small liberal arts college and two mid-sized public also been profoundly disappointed in each of these institutions,and in many of my colleagues,especially when ites to helping students and preparing them for the many responsibilities of focus on the business of running a university,and most faculty focus on their scholarship and teaching their deliberate attention is given to how students mature as individuals and social beings.

E)Having just retired from teaching at a public university,Im now returning to my hometown of Flagstaff,Arizona,to establish a tiny college—Flagstaff convinced theres a need for another type of education,one devoted to helping studentse into their own and into this beautiful and troubled people need an education that will provide them with meaning,hope, courage,and passion,as well as information and institutions,I believe,are particularly ill-suited to this type of education.

F)Theres no“best of”list when ites to tiny colleges,at least not around the country people are creating new colleges that provide an alternative to small liberal arts colleges,large public universities,and online education.

G)With only 26 students,Deep Springs is the smallest college in the country and,quite likely,the most atypical (非典型的) .Located on a working cattle ranch on the California-Nevada border,Deep Springs is a private,residential,two-year college for menmitted to educating students for “a life of service to humanity.”Founded by the electricity tycoon(大亨) in 1917,Deep Springs “curriculum”revolves around academics,labor,and addition to their courses, students are charged with running the 155-acre ranch and overseeing the functioning of the college. Students chair both the admissions and the curriculummittees.

H)“Living in closemunity with ones teachers and fellow students,and being forced to take on adult responsibilities,makes for ones growth as a person,"says William Hunt,who graduated last year. “To exist for very long in amunity like that,you have to get over the question of whether youre sufficiently talented or principled and get started worrying about how you can stretch yourself and your peers,how much you can manage to learn with them."

I)Sterling College,in Craftsbury Common,Vermont,is also very small-fewer than 100 students. Unlike Deep Springs,Sterling focuses its curriculum on environmental and social justice issues,but like Deep Springs it places a high value on personal responsibility and manual to its catalog,a college education at Sterlingbines“rigorous academics,roll-up-your-sleeves challenges, and good old hard work.”

J)The average tuition at a small liberal-arts college is $30,000 to $40,000 a year,not including the cost of living on campus,aspared to $8,000 to $10,000 a year for tuition alone at a public university. Of the tiny colleges,only Deep Springs doesnt charge tuition or room and board;students pay only for books and the cost of traveling to and from tiny schools are to be a player on the higher education scene,they will need to find a way to be truly affordable.

K)Doing so may not be that difficult so long as they do not pattern themselves too closely on existing e to believe that a good college should have many academic programs and excellent facilities,posh (豪华的`) dorms,an array of athletic programs,and a world-class student activity a good college without a climbing wall!We also have accepted the idea that college presidents,and their many vice-presidents,should be paid like their counterparts in the business world and that higher education requires an elaborate,up-to-date technology of this drives up the cost of education.

L)The “trick”to making tiny colleges affordable,if thats the right word,is its core, education is a human-to-human on his own college education,President Garfield oncemented that an ideal college would consist of nothing more than the legendary teacher Mark Hopkins on one end of a log and a student on the economics of a tiny college, in other words,might be similar to that of a tiny it is small,a tiny house costs less to build and less to furnish,insure,and the economic benefits of a small house dont end homes discourage homeowners from buying stuff that they really dont need,because theres no place to put it.

M)Im a late convert to the idea of tiny colleges,and I fully understand the need for many diverse types of educational research and job training are important,but tiny colleges arent suited for educational needs of aplex society are themselvesplex,and no single model can meet all of these Im now convinced theres an educational need thats now going almostpletely unmet:namely,the need to help young people transition into colleges can do this better than any other type of educational institution.

N)The ultimate justification for a tiny college is the conviction that each of uses into our full humanity by close interaction with those who know and care for us,and that one of the basic purposes of higher education is we give lip service to the idea that a college education will make us better people,when alls said and done,we think of higher education primarily in economic terms. Wevee to think of higher education as a means to make a living rather than make a alsoe to see higher education as a private good rather than a public colleges are not the answer to all of our educational requirements,but theyre an answer to one of our most basic educational necessities:the need to produce thoughtful,engaged,andpassionate human beings.

tiny American college situated on a cattle farm is devoted to educating students to serve mankind throughout their lives.

to the authors disappointment,the three institutions of higher learning where she taught largely ignore studentsgrowth as social beings.

colleges must be made affordable in order to play a role in higher education.

to a recent graduate from a tiny college,living together with faculty and fellow students is conducive to a students growth as a person.

than going small,most American universities are trying to go big.

a certain tiny college,rigorous academic work and traditional manual labor are integrated.

colleges focus on educating students to be well-rounded citizens instead of seeking their own expansion.

essence of education lies in the interaction between people.

her retirement,the author has decided to set up a tiny college in her hometown.

colleges are justified as it is believed that our growth into full humanityes through interaction with people near and dear to us.

If youre someone who has turned to snacking on junk food more in the pandemic(大流行病),youre not reporter Michael Moss says processed food is engineered to hook you,not unlike alcohol, cigarettes,or other harmful 2013 book,Salt Sugar Fat,explored foodpaniesaggressive marketing of those products and their impact on our his new book,Hooked,Moss updates the food giantsefforts to keep us eating what they serve,and how theyre responding toplaints from consumers and health advocates.

Processed food is inexpensive,its legal,and its is cueing us to remember those products and we want those products the food environment is one of those key things that makes food even more problematic for so many ,nostalgia (怀旧)in particular, plays a big role in the foods we panies discovered that if they put a soda in the hands of a child when theyre at a ball game with their parents,that soda will forever be associated with that joyous moment. Later in life,when that child wants to experience a joyous moment,theyre going to think of people seekfort in the snacks they remember from childhood.

Moss examines the waypanies capitalize on our memories,cravings and brain chemistry to keep us snacking.

One of the reasons I came to think that some of these food products are even more powerful,more troublesome than drugs can be is we eat is all about we begin forming memories for food at a really early we keep those memories for a this,the food industry spends lots of time trying to shape the memories that we have for their of the features of addiction that scientists studying drug addiction discovered back in the 1990s was that the faster a substance hits the brain,the more apt we are as a result to act nothing faster than food in its ability to hit the Moss,this puts the notion of “fast food”in an entirely new light as this isnt limited to fast food chains—almost 90%of food products in grocery stores are processed in the industry is about speed,from manufacturing to packaging.

Overall,Moss outlines the industrys dependence on making their products inexpensive,super delicious, and incredibly convenient for that more and more people care about what they put in their bodies and are wanting to eat healthier,thesepanies are finding it really difficult to meet that new demand because of their own addiction to making these convenience foods.

what way does Michael Moss think processed food isparable to alcohol and cigarettes?

A)They are all addictive.

B)They are all necessary evils.

C)They are all engineered to be enjoyed.

D)They are all in increasingly great demand.

does the author say plays a key role in the foods we crave?

B)They attempt to use consumerslong-term memories to promote addiction.

C)They try to exploit consumersmemories for their products as early as possible.

D)They endeavor to find what consumers remember about their products.

does the food industry operate from manufacturing to packaging,according to Moss?

A)Placing the idea of fast food in an entirely new light.

B)Setting no limit to the number of fast food chains.

C)Focusing on how quickly the work is done.

D)Prioritizing the quality of their products.

arepanies finding it difficult to satisfy consumersdemand for healthier food products?

A)They think speed of production outweighs consumershealth.

B)They believe their industry would perish without fast foods.

C)They have to strike a balance between taste and nutrition.

D)They are hooked on manufacturing convenience foods.

Passage Two

Questions 51 to 55 are based on the following passage.

Chimpanzees (黑猩猩),human beingsclosest animal relatives,share up to 98%of our humans and chimpanzees lead very different than 300,000 wild chimpanzees live in a few forested corners of Africa today,while humans have colonized every corner of the more than 7 billion,human population dwarfs that of nearly all other mammals—despite our physical weaknesses.

What could account for our speciesincredible evolutionary successes?

One obvious answer is our big could be that our raw intelligence gave us an unprecedented ability to think outside the box,innovating solutions to thorny problems as people migrated across the globe.

But a growing number of cognitive scientists and anthropologists ( 人 类 学 家 ) are rejecting that think that,rather than making our living as innovators,we survive and thrive precisely because we dont think for ,people cope with challenging climates and ecological contexts by carefully copying others.

In a famous study,psychologists Victoria Horner and Andrew Whiten showed two groups of test subjects- children and chimpanzees—a mechanical box with a treat one condition,the box was opaque,while in the other it was experimenters demonstrated how to open the box to retrieve the treat,but they also included the irrelevant step of tapping on the box with a stick.

Oddly,the children carefully copied all the steps to open the box,even when they could see that the stick had no practical is,they copied irrationally:Instead of doing only what was necessary to get their reward,children slavishly imitated every action theyd witnessed.

Of course,that study only included three-and additional research has shown that older children and adults are even more likely to mindlessly copy othersactions,and infants are less likely to over- imitate—that is,to precisely copy even impractical actions.

By contrast,chimpanzees in the study only over-imitated in the opaque the transparent condition—where they saw that the stick was mechanically useless—they ignored that step research has since supported these findings.

When ites to copying,chimpanzees are more rational than human children or adults.

Where does the seemingly irrational human preference for over-imitatione from?Anthropologist Joseph Henrich points out that people around the world rely on technologies that are often soplex that no one can learn them ,people must learn them step by step,trusting in the wisdom of more experienced elders and peers.

So the next time you hear someone arguing passionately that everyone should embrace nonconformity and avoid imitating others,you might laugh a little not chimpanzees,after all.

might explain humanshaving the largest population of almost all mammals?

A)They are equipped with raw strength for solving the most challenging problems.

B)They cope with the outside world more effectively than their animal relatives.

C)They possess the most outstanding ability to think.

D)They know how to survive everywhere on earth.

accounts for humansevolutionary successes according to a growing number of cognitive scientists and anthropologists?

A)They are better at innovating solutions.

B)They thrive through creative strategies.

C)They are naturally adaptive to ecological contexts.

D)They meet challenges by imitating others carefully.

does the author think is odd about the findings of the study by Victoria Horner and Andrew Whiten?

A)Children irrationally imitated every action of the experimenters.

B)Chimpanzees could tell the transparent box from the opaque one.

C)Chimpanzees could retrieve the treat more quickly than children did.

D)Children omitted the step of tapping on the box with a stick to open it.

is anthropologist Joseph Henrichs explanation for the human preference for copying?

A)It originates in the rationality of people around the world.

B)It stems from the way people learnplex technologies.

C)It results from people distrusting their own wisdom.

D)It derives from the desire to acquire knowledge step by step.

point does the author want to emphasize when he says“Were not chimpanzees”?

A)It is arguable whether everyone should avoid imitation.

B)It is characteristic of human beings to copy others.

C)It is desirable to trust in more knowledgeable peers.

D)It is naive to laugh at someone embracing nonconformity.

Conversation one.

ive just bought a new blender.

Whats that a blender?

A machine that blends food.

the electric kitchen appliance, exactly.

This one is state of the art. Ive been meaning to buy one for a while. I did thorough research on which specific model to get. I read through maybe hundreds of online user reviews. Anyway.

its amazing really what could be so special about it. I its just a blender.

Basically its just a very good one. It feels heavy and sturdy and well made. It also has lots of power and can easily cut and crush practically anything. This way. The soups and juices I makee out really fine and smooth with no lumpy bits.

I see I have never thought of getting one myself. It sounds like the kind of thing that for me personally I would rarely use.

Ive never had one before now that I do, I use it all the time. I make a fresh fruit juice in the morning, maybe not every morning but 3 or 4 times a week and it feels fantastic. Its a really healthy habit.

I can imagine that must feel quite satisfying. I can picture you getting all creative in the kitchen and trying out a multitude of different ingredients. Its obviously going to be healthier than buying packaged juice from a supermarket.

Its so much healthier. Its not even close did you know that store bought juice is like 10% sugar, right?

Then you bought it for the health benefits, mostly yes.

Basically, it allows me to have a more varied diet with a far wider assortment of nutrients, because its not only fruit in my morning juices. You see. I can also throw in vegetables, nuts, yogurt, cereals, anything that tickled my fancy.

Questions. 1 to 4 are based on the conversation you have just heard.

Question 1, what does the man say he did before buying the blender?

Question 2, what does the woman say she has never thought of doing?

Question 3, what does the man say is a really healthy habit?

Question 4, what do we learn about store bought juice from the conversation two?

Today we have a very interesting guest, mister thomas benjamin grimm, the mayor of burkington is here to talk about his job and responsibilities overseeing this charming village. Mr. Grimm, thank you for being here.

Thank you for having me.

Id like to start by stating the obvious burketon has be one of the most popular tourist destinations in the country and this has happened under your watch. Just how did you achieve this?

The achievements belongs to all the residents of burton. It was a shared effort where everybody pitched in for themunal good.

But how did this change happen? In about 10 years, burkton has gone from a relatively unheard of sleepy village to a must see destination.

Yes, the change has truly been remarkable. Burkton was always fortunate to be endowed with such a beautiful natural allure. The anbury hills above the village remain untouched by human development. The sonora valley just below it is equally stunning. The transformationmenced in a town hall meeting in spring 2008 over 10 years ago. Now when an overwhelming majority of neighbors voted in favor of motion, 836, this legislative proposal essentially set out to harmonize the aesthetic appearance of all the houses in berkton. The idea was that if all the properties looked a certain way with shared design features, then the village as a whole would look more beautiful. It worked, it certainly did.

Im looking now at a before and after photo and the change is truly remarkable. Its hard to believe its the same place. How do the neighbours feel now? Great pride.

I would say.

But what about the multitudes of visitors now crowding the streets? Is everyone happy about that?

The tourists we receive are a blessing as they havepletely revitalized our local economy. Every visitor is warmly wee.

Questions 5 to 8 are based on the conversation you have just heard.

Question 5, what is the question the woman asked mister grimm after the introduction?

Question 6, what do we learn about burkton of 10 years ago?

Question 7, what resulted from the passing of the legislative proposal motion 836.

Question 8, why does the man say the tourists are a blessing to bergen? Passage one,

researchers in the us have created a remote controlled robot that is so small. It can walk on the top of aus penny in research published in the journal science, robotics. A team at northwestern university said the crab like robot is millimeters wide. Researchers described it as the smallest ever remote controlled walking robot. The tiny robot can bend, twist, crawl, walk, turn and even jump without the use ofplex hardware or special power. The engineers said this is because the robot is powered by the elastic property of its body. To construct the robot, the researchers used a shape memory alloy material that transforms to its remembered shape when heated using a laser, the team is able to heat the robot at specific parts of its body, causing it to change shape as the robot deforms and goes back to its original shape. It creates movement from one place to another, because these structures are so tiny, the rate of cooling is very fast. Project lee, professor john a rogers said, in fact, reducing the sizes of these robots allows them to run faster. While the research is still in the exploratory phase, the team believes that technology could lead to micro sized robots that can perform practical tasks. In tightly confined spaces, you might imagine micro robots as agents to repair or assemble small structures or machines in industry or a surgical assistance to clear clogged arteries to stop internal bleeding or to eliminate cancerous tumors all in minimally invasive procedures. Rogers said.

Questions 9 to 11 are based on the passage you have just heard.

Question 9, what does the passage say about a team of researchers at northwestern university?

Question 10, what did the researchers say about the robot they created?

Question 11, what do the researchers expect their robots to do in the future?

Passage two, I dont want to boast or anything, but I have always considered myself something of an elite sleeper given the opportunity, I will sleep for marathon stretches and condose through the most extreme situations on one very rough ferry crossing on the route to the isles of silly. For example, my travelingpanion spent the entire 3 hour ride throwing up in the bathroom while I dozed happily on a plastic chair. Unfortunately, it hase to my attention that I am not an elite sleeper. After all. It seems I am just lazy because elite sleepers are defined as the approximately 3% of the population who are biologically programmed to need less sleep than the rest of us. According to a study that came out in march, elite sleepers have rare genetic changes, which means they can sleep fewer hours than mere mortals without any risk of cognitive decline, it may not be possible to change your own genes, but can you train yourself to need less sleep? Is there a non biological way to reach elite sleeper status? I have spent the past year trying to answer that question, not for fun, I should add because having a baby has severely disrupted my sleep for which I still have a great passion for a while. I assumed id be forced to be one of those people who jump out of bed at the crack of dawn. After a year of tough scientific study, however, I have discovered being forced to get up early in the morning is very different from being an early bird.

Questions 12 to 15 are based on the passage you have just heard.

Question 12. What does the speaker say she did on her ride to the isles of silly

Question 13. What do we learn from the passage about elite sleepers?

Question 14, what has the speaker been trying to find out over the past year?

Question 15, what has the speaker discovered after a year of tough scientific study?

Recording one if you read an article about a controversial issue, do you think youd realize if it had changed your beliefs? No one knows your own mind like you do. It seems obvious that you would know if your beliefs had shifted. And yet a new paper in the quarterly journal of experimental psychology suggests that we actually have very poor awareness of our own belief change, meaning that we will tend to underestimate how much weve been swayed. By a convincing article, the researchers recruited over 200 undergraduates across two studies and focused on their beliefs about whether physical punishment of kids is an effective form of discipline. The students reported their initial beliefs about whether physical punishment is an effective way to discipline a child on a scale from onepletely disbelief to ninepletely believe. Several weeks later, they were given one of two research based text to read. Each was several pages long and either presented the arguments and data in favor of physical punishments or against it. After this, the students answered some questions to test theirprehension and memory of the text. Then the students again scored their belief in whether physical punishment is effective or not. Finally, the researchers asked them to recall what their belief had been at the start of the study. The students belief about physical punishment changed when they read a text that argued against their own initial position. Crucially, the memory of their initial belief was shifted in the direction of their new belief. In fact, their memory was closer to their current belief than their original belief. The more their belief had changed, the larger this memory bias tended to be suggesting the students were relying on their current belief to deduce their initial belief, the memory bias was unrelated to the measures of how well theyd understood or recalled the text, suggesting these factors didnt play a role in memory of initial belief or awareness of belief change. The researchers concede that this research was about changes to mostly moderate beliefs. Its likely the findings would be different in the context of changes to extreme or deeply held beliefs. However, our beliefs on most topics are in the moderate range. And as we go about our daily lives reading informative material, these intriguing findings suggest we are mostly ignorance of what we just read has updated and altered our own position. Questions.

16 to 18 are based on the recording you have just heard.

Question 16. What does a new paper in the quarterly journal of experimental psychology suggest?

Question 17, what happened when the students read a text that argued against their own initial position?

Question 18, what did the researchers concede concerning their findings according to as the american population grows?

So does the number of american moms recording to as the american population grows? So does the number of american moms, but more than a century after mothers day became an official holiday. Even as that number increases, the share of the american population who are mothers is at the lowest point in 1/4 century. Its frequently noted that fertility rates are falling sharply in richer countries, but the less observed consequence of this trend is that a decline in births can also mean a decline in motherhood in general. According to my analysis of data from the census bureau, the decline of american motherhood is real occurring very quickly and may continue for some time yet. Not only are moms making up less of the population, but their characteristics are changing too. And in a way that might be linked to their proportional decline, moms today tend to be older than in the past. Just looking at recent years, the change in age specific birth rates has been drastic. In just the past few years, the peak childbearing age range for american women has advanced from that of 25 to 29 that To 34. Meanwhile childbearing among women under 20 has fallen by half or more. While childbearing among women 35 and older is rising. One positive consequence of this age shift is that a larger proportion of new mothers are economically prepared to raise children less positively. However, many women find that as they age, they cant have as many kids as they would like. Plus having children later in life can increase the risk of healthplications. These finer points aside, one major consequence of the older moms trend is that fewer years of a womans life are spent as a mother. This means that at any given time, a larger share of women and thus of the whole population will report not having children in government surveys. In other words, later motherhood means less motherhood, even as motherhood rates decline, mothers day will endure. In fact, despite the demographic shift, retail spending on the holiday appears to be rising. It is hard to say if mothers day spending is rising more than one would expect, given that the american population keeps growing. But one factor might be that the proportion of women who are the mothers of adult children is rising. Those adult children may spend more generously when ites to celebrating the moms. They no longer live with.

Questions, 19 to 21 are based on the recording. You have just heard.

Question 19. What does the speaker conclude from her analysis of the census bureaus data?

Question 20. What does the speaker say is a positive consequence of the age shift in childbearing?

Question 21. What might be one explanation for the rise in retail spending on mothers day?

Recording three. Since nasa published a paper in 1989, claiming that house plants can soak up pollution and toxic chemicals, businesses and homeowners have increasingly invested in greenery to help clean their air. But a new analysis suggests it could actually take more than 1,000 plants per square meter to gain a benefit any greater than simply opening a couple of windows. The problem lies in the fact that NASA conducted their tests in sealed containers that do not simulate the conditions in most peoples homes or offices. The space agency was primarily concerned about keeping the air fresh for astronauts cut off in biosphere or space stations and helping tobat sick building syndrome, which had be a problem due to the super insulated and energy efficient officers of the late 1970s. By the early 1980s, workers regularlyplained of skin rashes, sleepiness, headaches and allergies as they breathed in toxic chemicals from paints and plastics. Nasa found that certain plants could remove chemicals from the air. And even today, garden centers rmend the plants for air cleaning properties. However, a new evaluation of dozens of studies spanning 30 years found that house plants in a normal environment have little impact. In fact, natural ventilation is far better at cleaning the air. The researchers also calculated the clean air delivery rates for plants in the studies they analyzed and found that the rate at which plants dispersed thepounds was well below the usual rates of air exchange in a normal building caused by the movements of peopleing and going opening doors and windows. Many of the studies did show a reduction in the concentration of volatile organicpounds over time, which is likely why people have seized on them to praise the air purifying virtues of plants. But the researchers calculation showed it would take 10 to 1,000 plants per square meter of floor space topete with the air cleaning capacity of a buildings, air handling system, or even just a couple of open windows in a house. In contrast, NASA sealed experiment rmended one pot plants per 100 square feet. This is certainly an example of how scientific findings can be misleading or misinterpreted over time. But its also a great example of how scientific research should continually re examine and question findings to get closer to the ground truth of understanding whats actually happening.

Questions 22 to 25 are based on the recording. You have just heard question 22. What does nas as 1989 paper? Claim house plants can do.

Question 23. What is said to be the problem with nas as study reported in its 1989 paper?

Question 24. What is the finding of a new evaluation of dozens of studies spanning 30 years?

Question 25. What does NASA sealed experiment rmendation exemplify in scientists pursuit of truth?

Thank you for meeting with me，steven at such short notice。

not a problem，margaret。Now please give me some good news。Have you agreed to my last proposal？

I have indeed and I wish to sign the agreement pending one small change to be made to the contract。

Margaret，we have been through this for almost a year now back and forth making alterations。Are you sure you want to make a sponsorship deal for your clients or not？I ask this because frankly，some people at my end are running out of patience。I understand your concerns。

but as im sure you understand，we hold our clients best interests to be of the utmost concern。We thereforeb through the fine details of all contracts。Rest assured we all appreciate your firms patience。

Fine。So what changes do you wish to make？

Essentially，we would like the new deal to exclude the middle east。

Thats all the middle east。

Why my client has a couple of other perspective marketing deals frompanies in the middle east。Those offers should they materialize would exclusively employ my clients image in the middle east only。Therefore，in order to avoid any conflict，we would need to ensure that both marketing campaigns do not overlap geographically。

What business sector in the middle east are we talking about here？

Real estate.

that should be okay then so long as the product is very different from our food and beverage market，there should be no conflict of interest。Nevertheless，I will have to run this through my people。I dont foresee any problem though，the middle east is a negligible market for us，but I still need to check this with a couple of departments。

Next，we have a special science related news story。Paula hancock is at the denver observatory。Paula，what is the big story over there？ the astronomers on site here are very excited。In fact，space enthusiasts all across north america and the rest of the northern hemisphere will be congregated on mountain tops tonight to watch the night sky。

Whats the big event？Is there an eclipse happening soon？

Tonight the earth wille into close proximity with the oppenheimeret。It is the closest our planet has been to such a phenomenon in over 100years。For this reason。It is expected that thousands of people will gaze up at the sky tonight in order to see this formidable object。

How far away is thismon？Will people be able to see it with the naked eye？

The oppenheimeret will still be millions of miles away on the edge of our galaxy。But nevertheless，this is a relatively close distance，close enough for people to observe in good detail through a telescope。People will only see a blur without one。However that does not mean one needs professional equipment。Even the most ordinary of telescopes should be conducive for people to observe and wonder at this flying object。

Many of our viewers will be wondering how they too can take part in this once in a lifetime event。Where will thisment be in the sky？How can people find it？

Theet will be almost exactly due north at60°above the equator。However，finding theet is indeed very tricky and scientists here have told me there are plenty of phone apps that will facilitate this。

dietary guidelines form the basis for nutrition advice and regulations around the world。While there is strong scientific consensus around most existing guidelines。One question has recently stirred debate。Should consumers be warned to avoid ultra processed foods？Two papers published today in the american journal of clinical nutrition outline the case for and against using the concept of ultra processed foods to help inform dietary guidelines beyond conventional food classification systems。The authors，carlos monteiro of the university of sao paulo and arna ostrich of novo nordisk foundation。Well discuss the issue in a live virtual debate。August14th，during nutrition，2024live online。The debate centers around a system developed by monteiro and colleagues that classifies foods by their degree of industrial processing，ranging from unprocessed to ultra processed。The system defines ultra processed foods as those made using sequences of processes that extract substances from foods and alter them with chemicals。In order to formulate the final product，ultra processed foods are characteristically designed to be cheap，tasty and convenient。Examples include soft drinks and candy，package snacks and pastries，ready to heat products and reconstituted meat products。Studies have linked consumption of ultra processed foods which are often high in salt，sugar and fat weight gain and an increased risk of chronic diseases，even after adjusting for the amount of salt，sugar and fat in the diet，while the mechanisms behind these associations are not fully understood，montero argues that the existing evidence is sufficient to justify discouraging consumption of ultra processed foods in dietary rmendations and government policies。

Human creativity benefits from constraints。According to psychologists，when you have less to work with，you actually begin to see the world differently。It constraints。You dedicate your mental energy acting more resourcefully when challenged you figure out new ways to be better the most successful creative people know that constraints give their minds the impetus to leap higher。People who invent new products are not limited by what they dont have or cant do。They leverage their limitations to push themselves even further。Many products and services are created because the founders saw a limitation in what they use。They created innovation based on what was not working for them at the moment。Innovation is a creative persons response to limitation in a 2015study which examined how thinking about scarcity or abundance influences how creatively people use their resources。Ravi matter at the university of illinois and meng zhu at johns hopkins university found that people simply have no incentive to use whats available to them in novel ways。When people face scarcity，they give themselves the freedom to use resources in less conventional ways because they have to obstacles can broaden your perception and open up your thinking processes，consistent constraints，help you improve at connecting unrelated ideas and concepts。Marissa meyer，former vice president for search products and user experience at google。Once wrote in a publication on bloomberg constraints，shape and focus problems and provide clear challenges to ovee。Creativity thrives best and constraint。

Recording one different people use different strategies for managing conflicts。These strategies are learned in childhood。Usually we are not aware of how we act in conflict situations。We just do whatever seems toe naturally，but we do have a personal strategy and because it is learned，we can always change it by learning new and more effective ways of managing conflicts。When you get involved in a conflict，there are two major concerns you have to take into account，achieving your personal goals and keeping a good relationship with the other person，how important your personal goals are， how important the relationship is to you affect how you act in a conflict。Given these two concerns，five styles of managing conflicts can be identified when the turtle turtles withdraw into their shells to avoid conflicts。They give up their personal goals and relationships。They believe it is easier to withdraw from a conflict than to face it。Two，the shark sharks try to overpower opponents by forcing them to accept their solution to the conflict they seek to achieve their goals at all costs。Sharks assume that conflicts are settled by one person winning and one person losing。Winning gives sharks a sense of pride and achievement losing gives them a sense of weakness，inadequacy and failure。Three，the teddy bear。Teddy bears want to be accepted and liked by other people。They think that conflict should be avoided in favor of harmony and believe that conflicts cannot be discussed without damaging relationships。They give up their goals to preserve the relationship for the fox foxes are moderately concerned with their own goals and about their relationships，with other people。They give up part of their goals and persuade the other person in a conflict to give up part of his goals。They seek a solution to conflicts where both sides gain something5，the owl owls view conflicts as problems to be solved。They see conflicts as improving relationships by reducing tension between two people。They try to begin a discussion that identifies the conflict as a problem by seeking solutions that satisfy both themselves and the other person。Owls maintain the relationship。Owls are not satisfied until a solution is found that achieves their own goals and the other persons goals。And they are not satisfied until the tensions and negative feelings have been fully resolved。

Recording two，the genetic code of known species of animals and plants living on earth will be mapped to help save species from extinction and boost human health。Scientists hope that cracking the genetic code of plants and animals could help uncover new treatments for infectious diseases。Slow aging improve crops in agriculture create new bio materials in britain，organizations including the natural history museum，the royal botanic gardens，a queue and the wee sanger institute have joined forces to sequence britains 66,000 species of animals and plants dubbed the darwin tree of life project。It is expected to take 10 years and cost￡100 million oncepleted。All the information will be publicly available to researchers。Many scientists believe that earth has now entered the 6th mass extinction with humans creating a toxic mix of habitat loss，pollution and climate change，which has already led to the loss of at least 77 species of mammals and 140 types of birds。Since1500，it is the biggest loss of species since the dinosaurs were wiped out 66 million years ago。Scientists say that sequencing every species will revolutionize the understanding of biology and evolution，bolster efforts to conserve as well as protect and restore biodiversity。Doctor tim littlewood，head of life sciences department at the natural history museum said whether you are interested in food or disease，the history of how every organism on the planet has adapted to its environment is recorded in its genetic makeup，how you then harness that is dependent on your ability to understand it。We will be using modern methods to get a really good window on the present and the past。And course，a window on the past gives you a prospective model on the future。Sir jim smith，director of science at wee said，try as I I cant think of a more exciting，more relevant，more timely or more internationally inspirational project。Since1970，humanity has wiped out60%of animal populations about 23,000of80,000 species surveyed are approaching extinction。We are in the midst of the 6th great extinction events of life on our planet which not only threatens wildlife species，but also imperils the global food supply。As scientists，we all realise we desperately need to catalogue life on a fragile planet。Now I think were making history。

Questions19to21 are based on the recording you have just heard

question do scientists hope to do by cracking the genetic code of plants and animals？

Question 20，what do many scientists believe with regard to earth？

How does sir jim smith，director of science at wee describe the darwin tree of life project。John dunn，the english poet wrote in the 17th century，no man is an island entire of itself。Every man is a piece of the continent，a part of the main。Now a british academic has claimed that human individuality is indeed just an illusion，because societies are far more interconnected at a mental，physical and cultural level than people realize。In his new book，the self delusion。Professor tom oliver，a researcher in the ecology and evolution group at the university of reading argues there is no such thing as self。 And not even our bodies are truly us.
