阅读下列短文，从每题所给的'四个选项（A、B、C和D）中，选出最佳选项，并把答案写在答题卷上。 A．

A car needs gas to run and your body also needs food to work for you. Eating the right kind of food is very important. It can keep your body strong, so take care of what you eat.

There are four main food groups altogether. The dairy products group has food like milk, cheese and sour milk. The other three groups are the meat and fish group, the fruit and vegetable group, and the bread and rice group. Each meal should have at least one food from all the four main groups. With all these food together you will be given enough energy during the day.

It is easy to get into bad eating habits. You may eat your breakfast in a hurry to get to school on time. Or you may not have time for a good lunch. It may seem easy to finish your supper with fish and chips all the time. But you will find yourself tired during these days and you can not think quickly.

Watching what you eat will help keep your body healthy and strong. It is also good to take some exercise. It will help you eat more if you take a walk or play games in the open air. Having a good eating habit with some exercise is the key to your health.

31. Which of the following diets do you think is the best one?

A. Eggs, tomatoes and Milk, bread, cabbages and beef.

C. Corn, fish, cream and pork. D. Rice, beancurd, apples, fish and chicken.

32. Which of the following is a good eating habit?

A. every person needs food to grow wellB. taking exercise can keep your body strong

C. right kind of food with exercise will keep you healthy

D. enough energy helps people think more quickly

B.

Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food ,get enough sleep, and exercise regularly.

Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料).Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质) ,like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don't overeat. It is not helpful to be overweight.

Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little a amount of sleep may even result in a change of personality (人的个性).Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.

Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.

If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.

34. According to the passage,_________.

A .we should always keep fit

C. one can eat a lot to stay in good shape

D. one needn't take any exercise if he is healthy

order to keep good health, ___________ .

C. people should eat according to the foods nutrition D. we must try to sleep now and then

36. Eating more and sleeping less________.

A. can keep healthy B. is no good for you

C. gets you more energy D. will keep your personality

writer explains ________in this passage.

A. how to eat B. the importance of doing exercise

C. how to keep healthy D. what to eat

title of the article should be___________ .

A. Eating and Exercising B. How Vitamins Work in Man's Body

C. Staying Healthy D. Sleeping Well

C.

Isn't it astonishing how much time we spend talking about food? “Have you ever eaten …?” “What did you have for lunch?” and so on. And yet when you travel from one country to another, you will find that people have quite different feelings about food. People often feel that what they eat is normal (正常) and that what other people eat is strange or silly. In most parts of Asia, for example, no meal is complete without rice. In England, people eat potatoes every day. In the Middle East, bread is the main part of every meal. Eating like so many things we do, becomes a habit which is difficult to change. Americans like to drink a lot of orange juice and coffee. The English drink tea four or five times every day. Australians drink a great deal of beer, and the French drink wine every day.

The sort of meat people like to eat also differs from one country to another. Horse meat is thought to be delicious in France. In Hong Kong, some people enjoy eating snakes. New Zealander eat sheep, but they never eat goat meat. The Japanese don't like to eat sheep meat be-cause of its smell, but they enjoy eating raw fish (生鱼).

So it seems that although eating is a topic we can talk about for hours, there is very little common sense in what we say it. People everywhere enjoy eating what they have always eaten, and there is very little we can do to change our eating habits.

39. Which of the following is true according to the article?

A. All people have the same feeling about food.

B. In most parts of Asia, people usually have rice for meals.

C. People often consider other people to be strange or silly.

D. The topic people spend time talking about is bread and meat.

40. People in different countries .

A. drink the same sort of wineB. have the same eating habit

C. eat different kinds of meatD. have the same tea at different time within a day

41. The Japanese don't like to eat sheep meat .

A. because they dislike its smellB. because it is too expensive

C. because it is easy to go badD. because they think it will do harm to their health

42. English people drink tea four or five times a day .

A. because they get thirsty easilyB. because there is plenty of tea in Britain

C. because of their drinking habitD. because they have enough time to do so

难点讲解

1. Eric runs in after it, followed by a big dog, walking very slowly.

埃里克跟着球跑进来，后面跟着一条大狗，狗走得很慢。

这句话里有两个不同层面上的状语：过去分词短语“followed by a big dog” 是谓语“runs in”的伴随状语，而现在分词短语“walking very slowly”描述的是大狗跟随埃里克进来的行走方式，是动词“follow”的状语。

伴随状语通常由现在分词短语、过去分词短语或介词短语承当。当伴随动作由主语发出时，用现在分词，当伴随动作由其他人或物发出时用过去分词。例如：

He ran after the thief, shouting angrily.

She sat nervously in the grand sitting room, watched closely by the butler.

The soldiers stood silently along the pass, rifles in hand.

2. You weren’t supposed to come home until tomorrow.

你们应该明天才回家的。

be supposed to do sth:被期望或要求去做， 本应该去做。例如；

You are supposed to hand in your articles this Friday.

Girls are supposed to behave more quietly in this country.

在肯定句中until 必须和持续性动词连用时，在否定句里它主要和短暂性动词连用也可以和持续性动词连用，表示直到某时某个动作才开始。Until 还可以用在强调句中。Not until 放在句首时，句子要倒装。例如：

He slept until 8 o’clock.

He didn’t wake up till e8 o’clock.

It was not until 8 o”clock that he woke up.

Not until 8 o’clock did he wake up.

I won’t be free till Friday.

3. The money with which you were to buy dog food is gone, but Spot looks so hungry.

本该用来买狗食的钱不见了，但斑点狗看起来饿得厉害。

“with which you were to buy dog food” 是定语从句， 当关系代词是介词宾语时，介词常放在关系代词之前。例如：

the village we used to live in→the village in which we used to live

主语＋be动词+不定式表示“按计划将要做”，例如；

We are to hold up the enemy while our troups retreat.

The presidential candidate is to make a speech in our town on his way to Washington.

4. We thought you were an adult, a person from whom we could expect good decisions.

我们原以为你是个成年人，一个我们可以指望他做出正确决定的人。

划线部分是“an adult” 的同位语， 它 和“an adult”所指相同，句法功能也相同，是对“an adult”含义进一步的说明。这个同位于本身又带有定语从句from whom we could expect good decisions 。

Expect sth from sb: 期望从某人那里得到或看到某事，例如： You can never expect generosity from a miser.

5. This is not a family where bad behavior goes unpunished.

我们家不是一个放纵不良行为的家庭。

根据上文，this是指 our family。动词go 后面可以跟形容词，表示“变得”，例如：

go bad（变质）, go dry（变干）, go mad（发疯）, go international （国际化）。Go 和一些含否定意义的形容词连用，则表示“不受……的， 未被…的”,如： go unchallenged, go unnoticed.

His theory has gone unchallenged in the world for half a century.

It’s strange that such a mistake can go unnoticed in the textbook.

6. If they knew that Spot was ill and we used the money to take him to the vet…

假如他们知道Spot得了病， 而我们用那笔钱带他去看兽医的话……..

这句话用的是虚拟语气， 省略的部分是： they would understand why the money is gone and the house is a mess. 当说话人只表示一种假设的情况、一种主观愿望，即认为动词所表示的动作或状态并非真实时，使用虚拟语气。表示和现在事实相反时，主句用过去将来时，条件从句用一般过去时。例如：

If I were you, I should wait till next week.

I she saw you now, she wouldn’t recognize you.

7. None of us stopped to think and we should have.

我们本应当停下来想想，而我们都没有那么做。

Stop to do表示停下来去做另一件事， stop doing则表示停止正在做的事情。 should have

也是一种虚拟语气，表示过去本应当做的事情。这里完整的句子应该是：

We should have stopped to think, but none of us did.

8. Can you explain to me now why the house was a mess and what you did with the cash we left?

你现在能向我解释为什么家里乱成一团，而你又把我们留下的钱拿去干什么了吗？

Be (in) a mess表示“乱成一团”； do with 表示“处理、处置”常和what 连用，它和deal with 不同，deal with 表示“处理、应付” we left 虽然只有两个单词，却是一个定语从句，它前面省略了作宾语的关系代词that或which。
