plateau (高原) have been used to the high speed trains flying by above them.
"The heavy use of the underpasses (铁路下过路口 )shows the animals"
migration (迁徙)habits have not been affected by the railway," said Yang Qisen,
who has been studying the railway"s impact (影响) on wildlife since it opened
five years ago.
Yang, who is a researcher with the Institute of Zoology under the
Chinese Academy of Sciences (中科院动物研究厅), said a group of 3,000
antelopes live mostly in eastern Qinghai Province. However, every June, some
of them migrate to the Kekexili region of western Qinghai and northeastern Tibet
to give birth to their young.
The animals make their return journey in August, which means they pass
under the railway twice a year, he said.
For the past five years, between June and September, Yang and his team
have stayed near the railway to find out what it had done on local wildlife. They
have paid close attention to the migration patterns of the antelopes.
In 2004, 96 percent of the migrating antelopes were seen using the
underpasses. After 2005, the figure rose to 98 percent, Yang said.

Scientists are trying to make the deserts into good land again. They want to
bring water to the deserts, so people can live and grow food there. They are
learning a lot about the deserts. But more and more of the earth are becoming
deserts all the time. Scientists may not be able to change the deserts in time.
Scientists think that people make deserts. People are doing bad things to the
earth. (1)Some places on the earth do not get very much rain. But they still do
not become deserts. This is because some green plants are growing there. Small
green plants and grass are very important to dry places. Plants do not let the hot
sun make the earth even drier. Plants do not let the wind blow the soil away.
(2)When a little bit of rain falls, the plants hold the water. Without plants, the
land can become a desert much more easily.
2.
4. Why is more and more land becoming deserts while scientists are trying to
make the deserts into good land?
5. Why are small green plants and grass important to dry places?
Europe, Germany (德国) and northern European countries work very hard to
improve the environment. The people in Germany put their rubbish into different
bags-paper in one bag, plastic in another bag, etc. Therub- bish is then taken
away and, if possible, recycled(回收) There are laws that do not allow people
to burn too much coal.
In the 1970s, as people learned more about environmental problems, the
"Green" movement (运动) began and soon spread all over Europe. The "Green"
movement tries to get governments to protect the environment. It collects
information about how industry is damaging (破坏) the environment and tells
newspapers.
started to protect the environment. By now more than l, 000 cities around the world have had a No Car
Day.
The first No Car Day in China was in Chengdu in 2001. Other cities, including-Taipei, Shanghai and
Wuhan, also support(支持)the day.
In Beijing, more and more people are joining in the ac- tivity. It asks drivers to leave their cars at
home for one day each month and walk or ride a bike to work. It also calls on Beijingers not to use cars
on June 5 (World Environment Day). The slogan(口号) for the day is, "If we drive for one less day, we
can have one more nice day. "So far, more than 200, 000 drivers have shown their support. "We can"t
control the weather, but we can choose not to drive, " said Wu Zonghua, a car club chairman. Beijing is
trying to have 238 blue sky days this year. In the first quar- ter of this year, Beijing only had 52 blue sky
days. This was 11 days less than the number for the same period last year. Much of the dust (灰尘)
comes from the desert (沙漠), but cars cause most of the air pollution(污染). We must do more for
No Car Day.
B. four
C. five
D. six
B. to enjoy having a day off
C. to leave their cars at home for repair
D. to ride a bike or walk instead of driving to work
last year in Beijing.
B. 63
C. 41
D. 238
B. dust
C. weather
D. rubbish
B. people will have one more World Environment Day each month
C. more and more people won"t drive on No Car Day in Beijing
D. more people in the world won"t drive any more
years. It could be getting warmer on its own, but many scientists think that people
are making the Earth warmer by making a greenhouse effect (湿室效应).The
greenhouse effect is important. Without it, the Earth would not be warm enough
for us to live on. But just a little warmer than it is now could cause problems for
humans, plants and animals.
Many of the things we do every day can change the Earth"s temperature by
sending greenhouse gases (废气)into the air. We send greenhouse gases into the
air when we watch TV, turn on lights, dry hair, play video games, wash or dry
our clothes or drive cars. The rubbish (waste) from factories and homes also
produces greenhouse gases.
Even a small change in temperature can affect (影响)our weather. This can
cause changes in the sea levels, the air, flooding and our fresh water.
The change in the temperature can also cause changes in the living places
for animals and plants, endangering many animals.
Global warming (全球变暖)is a big problem, and every little bit we do
can help. We can save electricity. We can save energy in other ways such as by
taking buses or walking rather than driving cars. We can recycle to reduce the
rubbish and save natural resources such as trees, oil and metals. We can buy
products that don"t do bad to the environment and we can turn to solar energy.
Remember the little bit that you do will bring a better world.
B. Walking to school.
C. Driving a car.
D. Watching TV.
realize _____.
B. the earth is getting warmer in 100 years
C. the greenhouse effect is important
D. humans are making the earth warmer
B. be safer
C. have a cleaner earth
D. have a better world
B. Paragraph 3
C. Paragraph 4
D. Paragraph 5
B. we don"t need to do anything
C. we can do something to help
D. we can do something to stop it
