A desert is a large land of sand. There is very little rain and not many plants. The size and the place of the world's desert are always changing. In the last hundred years,deserts have become more and more. That's mainly because of men. In the nineteenth century some people brought a kind of little animal called rabbit to Australia from England. Today there are millions of them. They eat every plant they can see. The great desert in the center of Australia is becoming bigger.

  There are places in North Africa where great cities once stood. There were gardens and trees and grass. But now these places are desert. Scientists*?studied the land to find out what happened. Many of them thought the land died when the trees were cut down.

  Trees help other plants grow. And they keep the earth from blowing away. In forests, leaves on the ground keep rain water from running off.

  Men can make deserts, but they can also stop them from getting bigger. For example, in China, the Great Green Wall has been built and it has already saved a lot of land. But more "Great Green Wall" are still needed all over the world. Can we stop deserts from getting bigger and save the land? Yes,we can. And we must.

 Thirty years ago,Lake Ponkapog was full of life. Many birds and animals lived beside the water, which was full of fish. Now there are few birds, animals and fish. The lake water is polluted. It is filled with strange plants.

How did this happen？First, we must think about how water gets into Lake Ponkapog. When it rains, water comes into the lake from all around. In the past,there were forests all around Lake Ponkapog, so the rainwater was clean.

  Now there are many homes around the lake. People often use chemicals in their gardens. They use other chemicals inside their houses for cleaning or killing insects(昆虫) .There are also many businesses. Businesses use chemicals in their machines or shops. When it rains, the rainwater picks up all the chemicals from homes and businesses and then carries them into the lake. They pollute the water and kill the animals.

  Boats on the lake are also a problem. Lake Ponkapog is a popular place for motorboats. But oil and gas from boats often get into the lake. So more harmful chemicals go into the water in this way.

  People around the lake love this lake and want to save it. Will it be possible? A clean lake must have clean rainwater going into it. Clean rainwater is possible only if people are careful about chemicals at home and at work. They must also be more careful about gas and oil and other chemicals in the ground. And they mustn't use motorboats any more on the lake. All these may change people's lives. But only then can Lake Ponkapog be a beautiful clean lake again.

(   ) 1. In the past，the water in Lake Ponkapog was made clean by        .

A.     be less careful about chemicals

    B.     use more gas and oil

    D.     change their daily lives

 In most parts of the world, many students help their schools make less pollution(污染) .They join "environment club(环境俱乐部) ".In an environment club,people work together to make our environment clean.

  Here are some things students often do.

traffic. People say it's 8 to ride bikes. When you are riding, there is no pollution. But even in developed countries, most people don't go to work by bike.

So more people 9 their bikes and go to work by car,then things are getting worse and worse. We should have special roads only for bikes and make it 10 difficult and expensive for drivers to take their cars into the city that they will go back to use their bikes.
