　　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.
