阅读短文，从A、B、C、D四个选项中选出可以填入空白处的正确答案。
As we all know, the environment around us is getting worse and worse. In some places we can’t see fish 16 in the river or trees on the hills. Some people even have no clean water to drink.
Recently, a new life style called low carbon（低碳）life is spreading every corner of our country. The meanings of low carbon are 17 energy and no waste. It is such an important project that I can’t wait to express my ideas on how to promote it.
First, we should 18 a no-car day every week in our school. Because cars not only cause serious air pollution but also waste energy. 19 the no-car day, neither students 20 teachers are allowed to drive to school. At the same time, just walk or run. Use our legs and enjoy the fun.
Second, we had better not use plastic bags 21 . No one can stand the“white pollution”，
22 it is wise to use cloth bags which can be used again and again.
23 ，one thing that we should keep in mind is that every big thing comes from the small details. So, as students, we ought to turn 24 the lights the moment we leave, use 25 sides of the paper, and reuse our textbooks and so on.
All in all, it weighs greatly for all of us to put the low carbon lifestyle into practice. Just set our mind to these：no-car days, no plastic bags, and no waste. Let’s do it now.
( )16. A. swims B. swimming C. to swim D. swam
( )17. A. below B. high C.above D. low
( )18. A. set off B. set up C. put on D. put down
( )19. A. In B. At C. On D. With
( )20. A. nor B. or C.both D. and
( )21. A. any more B. no more C. no longer D. never
( )22. A. because B. so C. but D. although
( )23. A. Finally B. 3rd C. 4th D. 5th
( )24. A. up B. down C. on D. off
( )25.A. both B. each C. every D. all
Ⅳ.阅读理解。（30分）
(A)
The earth is about 4,600 million years old. Modern man has lived on the earth for only 35,000 years, but during that time, we have changed our planet in many ways. Many of the things that we have done are good, but more are not good for the earth.
Water Pollution
A lot of people, birds and fish die each day because of water pollution. Factories have polluted the land and the water. As a result, many rivers and lakes are now dead.
Air Pollution
In big cities, factories, as well as cars, trucks and buses are the main causes of air pollution. Many people in cities now have serious health problems. For example, Mexico city used to be a beautiful sunny capital, but today it is always covered by thick brown clouds.
Soil Pollution
In order to have a good harvest, most of the farmers use chemicals too much in their fields. That’s bad for the soil. But this kind of pollution is difficult to stop.
Hope for the Future
These problems are very serious for our future, so all of us should do something to improve our environment. If we can stop pollution, our planet will become more and more beautiful and our health will be better. Let’s be greener people!

Is the whale the world’s largest fish No. It looks like a fish, but it is really a mammal (哺乳动物). Then what’s the world’s largest fish It’s the whale shark（鲸鲨）.
Although the whale shark is our biggest fish and lives in many oceans （海洋）around the world, few people have ever heard of it. Scientists have not been studying whale sharks for very long. Much more needs to be learned about them.
A whale shark is sometimes called a “gentle giant (温柔的巨人)”. It likes to be alone and doesn’t care a bit about divers or humans. The biggest whale shark weighed 24,250 pounds and was nearly 40 feet long. This makes it heavier and longer than a school bus.
Inside its huge mouth are great numbers of very small teeth. To count all of them, you’ll need to do some math. The whale shark’s teeth are arranged in rows. There are between eleven and thirteen rows on each jaw (颚) and around three hundred teeth in each row.
However, the whale shark rarely uses its teeth. It does not chew or bite its food. Large amounts of water are pulled into its mouth and then pushed out through its gills (鳃).
For a few months every year, a group of whale sharks comes to Ningaloo Reef, off Western Australia. This gives scientists a wonderful chance to study the large fish. Whale sharks do live in other oceans of the world, but no one knows their population. It is possible that our biggest fish may need protecting. It is one of the reasons why scientists continue to learn all they can about these gentle giants.
( )31. Little is known about whale sharks because scientists _____.
A. are not interested in learning about them
B. find them too difficult to catch
C. do not know the best places to find them
D. have studied them for a short time
( )32. Which sentence can tell us that whale sharks are gentle
A. They have large mouths.
B. They leave divers alone.
C. They have small eyes.
D. They live in many oceans.
( )33. How does the writer help us know what the whale shark’s mouth looks like
A. By giving reasons.
B. By describing colors.
C. By comparing sizes.
D. By using numbers.
( )34. The fifth paragraph is mainly about _____.
A. how a whale shark eats
B. what a whale shark eats
C. how different fish use their gills
D. what’s inside a whale shark’s mouth
( )35. Which of the following is the best title for the article
A. Gentle Giants B. The Diary of a Sailor
C. The Largest Animal D. My Life on the Sea
(C)
Stop and listen! What do you hear You may hear many different sounds. Some of those sounds may be noise. Noise is a loud or unwanted sound.
Many kinds of machines, such as motorcycles, jet planes (喷气式飞机), farm tractors can cause noise, and power motors can cause noise. And, to some people, rock music is also a noise.
What happens to people who live near noisy machines or use them over a period of time Doctors have found that these people have trouble in sleeping. And most importantly, constant (连续的) loud noise can cause loss of hearing.
Scientists use a unit of measure called a decibel(分贝) to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands measure over 120 decibels. Noise at such high level causes the greatest hearing loss.
根据短文内容，判断正(T)误(F)。
( )36.According to the passage, noise is all sounds that you can hear.
( )37.A “decibel” is a machine that makes loud noise.
( )38.Loud noise can help people sleep better.
( )39.Not all people think that rock music is a noise.
( )40.We can infer (推断) from the passage that noise is a serious problem.

Let’s do something to keep hazy weather away
Nowadays, hazy weather has appeared in many cities in China. The air pollution in these areas is very serious. That's because many factories and cars give off waste gas.
Because of the serious air pollution，people daren’t open windows to let in fresh air. When they go outdoors，they have to wear masks．Also，students have to stop outdoor activities to avoid breathing in bad air．On hazy days, many traffic accidents happen and many flights are delayed because people can’t see clearly．Last but not least，the serious air pollution has also caused many diseases and many people lose their 1ives.
As a student，we can go to school by bike instead of by car．We should call on our friends to take the underground or the bus to work．We can call on people to plant more trees and ask the government to improve the public transport service.
We believe if we take actions, the air will be as fresh as before.
