When you watch TV and play video games you make global(全球的) warming worse! It may seem hard to believe, but when electricity is made, so are greenhouse gases(温室气体). This means that every time you use electricity you help make global warming worse!

  Cars are also making global warming worse. They burn fossil fuels(化石燃料) in their engines, and send lots of greenhouse gases into the air.

 Global warming may be a big problem, but we can all help stop it. People can try to drive their cars less. Or even get ones that run on sunlight! You can also help. Let’s try one of these top ideas:

(1) Try to use less electricity. Turn off lights, your television, and your computer when you’ve stopped using them. To make electricity, fossil fuels are burned in big factories. But burning fossil fuels also makes greenhouse gases. You should also try to watch less TV.

 (2) Plant trees. Not only is it a fun thing to do, but it is also a great way to lower the number of greenhouse gases in the air. Trees take carbon dioxide out of the air when they grow.

(3) Don’t throw away your rubbish, try to recycle it. If rubbish is not recycled, it is put in the ground. There it rots(腐烂) and makes a greenhouse gas called methane(甲烷).So try to recycle cans, bottles, plastic bags and newspapers. It’ll make you feel great! And it’ll help the Earth.

1.If we _____, we may make global warming worse.

A. use less electricity                                         B. drive a car on sunlight

C. plant trees                                               D. throw away rubbish

2. ______ will make global warming worse.

A. Methane            B. Cans               C. Newspapers                      D. Bottles

3.Using less electricity does good to global warming because_______.

A. the less electricity is used, the more greenhouse gases are produced

B. the more electricity is used, the more greenhouse gases are produced

C. more electricity is used, less greenhouse gases are produced

D. less electricity is used, more greenhouse gases are produced

4.Which is the following is NOT TRUE according to the passage?

A. Driving cars on sunlight helps to stop global warming.

B. When cars burn fossil fuels, they produce greenhouse gases.

C. When trees grow, they send carbon dioxide into the air.

D. By planting more trees, we can lower the number of greenhouse gases in the air.

In the past, man did not have to think about the protection of his environment. There were not many people on earth, and natural resources seemed to be unlimited.
Today, things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue like this, human life on earth will not survive.
Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on the land. Yet, we continue to use bigger and more powerful machines to cut down more and more trees.
We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste products are still put into rivers or into the sea, and there are few laws to stop this.
We know, too, that if the population of the world continues to rise at the present rate, in a few years, there will not be enough food.
What can we do to solve these problems?
If we eat more vegetables and less meat, we will easily get more food. Land that is used to grow crops can feed five times more people than land where animals are kept.
The world population will not rise so quickly if people use modern methods of birth control.
Finally, if we educate people to think about the problems, we shall have a better and cleaner living place in the future.

The importance of protecting the environment
Problems	◆ More fish being caught. ◆ More 【小题1】     being cut down. ◆ More waste products being put into rivers. ◆ More【小题2】     being born.
Causes	◆ The world is becoming too 【小题3】     . ◆ Modern methods make the situation worse .
Result	We human beings will not survive on the earth.
Solutions	◆ Eat more vegetables and less meat so that more food will be available  for everyone. ◆ Use modern methods of 【小题4】     control so that the population will not grow too fast. ◆ Educate people so that the 【小题5】    will be better and cleaner.
