根据短文内容,选出最佳选项回答问题。
  The Earth has warmed by about half a degree (0.5 ℃) over the last 100
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.
1. Which of the following does not send greenhouse gases into the air?
A. Turning on a light.      
B. Walking to school.
C. Driving a car.          
D. Watching TV.

realize _____.
A. the earth could be getting warmer by itself
B. the earth is getting warmer in 100 years
C. the greenhouse effect is important
D. humans are making the earth warmer
3. Without the greenhouse effect, we would _____.
A. not be able to live      
B. be safer
C. have a cleaner earth    
D. have a better world
4. The writer gives us advice on how to save energy in _____.
A. Paragraph 2              
B. Paragraph 3
C. Paragraph 4              
D. Paragraph 5
5. Global warming is a big problem but _____.
A. we can't do anything to help
B. we don't need to do anything

There are many wetlands (湿地) in China and some of them have become the world‘s important wetlands. The Chinese Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province. They are home for many different kinds of birds and animals. The world’s largest Milu Deer Nature Reserve(自然保护区) is in them. More than 700 milu deer live freely there. There are not many red-crowned cranes in the world, but every winter you can see some in the Red-crowned Cranes Nature Reserve in the Yellow Sea Wetlands.
  The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine, too. They are really good places for wildlife. Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.
  Luckily, more and more people are beginning to realize the important of wetlands and wildlife. Every year, on February 2nd, many activities are held to tell people more about wetlands.
