高三英语单词单词篇1
we live in the world every day. we eat food, drink water, wear clothes, watch tv, use computers and so on. we are producing waste every moment.
generally speaking, there are four sorts of waste. they are material waste, organic waste, inorganic waste and poisonous & harmful waste. now, we are going to talk about each sort of waste one by one.
material waste: it means the waste of substance or things from which something else can be made. for example, people throw away the used metal products and buy a new one, so the old metal waste accumulates. at last, they become waste. for example, when people finish reading newspaper, the paper will become waste. when the glass is broken, it also becomes waste. nobody wants to use a broken window or drink with a broken glass or wear a pair of broken glasses. once it is broken, it becomes waste. the rate of using plastics is increasing day by day. people use plastic bags because they are convenient. when they get home, they throw the plastics way, paying no attention to the environment. the more convenience plastics brings to us, the more plastic waste is produced. this is called white pollution as most plastics are white. some of our products we use every day are made of rubber, just like the tyres and the bottom part of our shoes. it’s true that rubber plays an important role in our life. however, it also brings us some trouble when it has been used for a long time and becomes old. the old tyres become waste because it can’t break down by nature. this is really a big problem.
organic waste: it refers to waste from living things, including waste from animals, plants and people. some parts of vegetables are thrown away as waste because they don’t taste good. in the past, people cooked their food using burning coal, so there left the burned coal, which is useless, like the thrown vegetables. all this sorts of waste contain organism, so it is called organic waste.
actually, we also have inorganic waste, the opposite to organic waste, including building waste, broken pottery and china, and cinder.
the last part is harmful and poisonous waste, such as used batteries, electrical apparatus and medical supplies. computers and tv sets are one part of electrical apparatus. you see, the old electrical apparatus can set off some dangerous rays and make the soil harder, even damage the under ground water. mobile phones are as dangerous as computers and tv sets. as we know, x-rays can be used to examine patients, but the x-rays machines are dangerous when they are thrown away without any treatment. they can’t be used to treat the sick, but they still can give off rays. for the normal people, they can be dangerous. so, we must think about this problem.
as waste has four sorts, we can sort them into each sort that they belong to. it’s convenient to treat them after they are sorted. then we can deal with them sort by sort. we have thought out some methods like storing them in order to change them into plant food, or burning them in a huge stove and use the heat to make electricity. for the first way, the change rate is much too low and it may pollute the under ground water. for the second one, of course it’s wonderful if it’s easy to be tried out. but to build such a huge stove will cost too much. not a good method. now you see, treating waste is not an easy job.
from what has been discussed above, we can do something to our home—the earth. we should make full use of things. at the same time, we’d better reduce its harmful effect as much as possible.
we can do from the basic of waste. that’s to say, we can reduce the production of waste, and reuse and recycle them as much as we can. take material waste for example. nearly all of them can be recycled and reused. and, we should call for using things made of paper instead of plastics so as to protect our environment.
protecting the environment is not one person’s duty; it depends on all of us. what can we do? maybe a dozen..
in a word, use what can reuse as much as possible. remember, environment protection is not one’s duty!

非常感谢你给我这个机会来提一些建议来完善图书馆服务。我很喜欢我们有成千上万的书的图书馆，我也想给一些建议。
due to the fact that there is no plant in our library, i hope that you can add some in it .it will be a great thing to read in a library filled with plants. in my spare time, i often go to the library and read some books .and i find students have to stand between the shelves for hours .it is a little tired for them to do so. it may be a good idea to add some chairs. another suggestion is that school should reduce the students reading in the library. we are long for a quiet environment.
由于我们图书馆没有植物，我希望可以种一些植物在里面。在一个充满植物的图书馆看书是很棒的。在我的业余时间，我经常去图书馆看书。我发现学生们得站在两个书架间数时来看书。这样的话他们会有点累。加一些椅子也许会是个好主意。另一个建议是学校应该减少在图书馆看书的学生数量。我们都希望有一个安静的环境。

时间过得真快，转眼又是一年，今天上午，学校开始放寒假了。我与以往放假时一样，总会在假期开始的第一天，订一个切实可行的计划，目的是为了能够使自己在假期中，过得更加的充实和快乐，并能学习到更多的校外知识，欢欢喜喜喜过个年。
我要培养我的兴趣和爱好，我要跟爸爸一起练练书法，长大以后也能够写一手好字。多看电视里的新闻报道，了解社会。我还要多锻炼身体，保持身体健康。
我要坚持写日记、作文。以前，我写的日记“干干的”，主要就是缺少观察；以后，我打算每天看三十分钟的课外书，在寒假期间把一些所见所闻记录下来，并把有一些有意义的人或事写成文章。看一些优秀的作文，学习别人的写作长处。在网上查找写的好的文章，向人家学习学习。另外，我还要一个小册子，起名为“日记小材料”，平时发生一点小事都要留心观察，把一些精彩的东西记录下来，那可是写文章的'好材料哟！到时候要写东西，那就不愁“没事可写”了！
走亲访友，做到文明礼貌，尊敬长辈，向亲戚朋友介绍自己的学习情况，向同龄人交流学习心得。
这就是我的寒假计划，我不但要加强学习，也要多帮爸妈做事，大家觉得我这个寒假计划怎么样？

a boom in adult education
every tuesday and friday evening sees miss li，my neighbor and a secretary in a company rush home after a hard day’s work，gulp down her meals and then hurry out to catch the bus for her english class. miss li’s case is not unique，and now more and more city adults spend their leisure time trying to improve themselves at school or college.
there are a number of reasons for people to go back for their education. some people，like miss li，are doing it to acquire another degree or diploma to impress the society. to them more knowledge，or rather，more credentials means more opportunities for better jobs and quicker promotion.
other people，especially those who are laid off or out of employment go to vocational school to prepare to return to the job market. they are eager for new skills so that they can be qualified for the jobs in retail trade，administration，education and other service categories to which they are strange because most of them were blue-collar workers in the factory.
there are also people who come to take such courses as chinese traditional medicine，painting，calligraphy and photography. as their working weeks decline people begin to have time to fulfill their old dream of their heart’s desire.
out of necessity or out of interest，people go back to school for the common goal——to improve themselves，and this boom in adult education，in turn，helps to raise the intellectual standard of the whole country.
