任务型阅读
阅读下面短文，根据短文内容，完成表格中所缺的信息。每空一词。
Our world is in danger．We must do something to protect the environment．What are the main problems we face
The greenhouse effect
When we burn fuels such as petrol and coal, a gas called CO2 is produced．Too much of this gas pollutes atmosphere, and causes it to keep in too much heat．As a result of the greenhouse effect, the earth's temperature is increasing．This causes sea level to go up, and in the future may cause cities to disappear．
Cutting down forests
Every year, we destroy nature by cutting down huge areas of forests．This makes the greenhouse effect worse because trees take in CO2 and give out O2．Cutting down trees also destroys the homes of the animals that live in our forests, and causes the surface of the soil to be easily destroyed by rain．This can result in floods and even more damage to the environment．
Bad habits
Many of our habits cause pollution．People often use things once and then throw them away, or leave them on the ground as litter．This creates tons of rubbish and pollutes our land and seas．
In order to protect the environment, we need to take proper action．Chinese government has made laws and rules about dealing with the waste．We are getting serious about our bad habits now．We should only buy and use products friendly to the environment．We should also recycle as many things as possible．To reduce air pollution, we can take the bus or subway instead of driving．
If we just learn to live in new and different ways, we can make a difference．

Dear students，
The environment is important to us．As students, what can we do to protect the environment
To reduce white pollution, we should use fewer plastic bags when going shopping．We can use cloth bags instead．We should try to reuse old textbooks．Therefore, people needn't cut down more trees to make paper．In order to save energy, we should use the lift less．We should also save water and electricity．And we should plant more trees so that the air will be fresher．Besides, we'd better go to school on foot or by bike．It is also good for our health．
I believe that we can make the world a better place to live in by working together．
