问题    Scientists are trying to make the deserts into good land again. They want to bring water to the deserts, so people can live and grow food. They are learning a lot about the deserts. But more and more of the earth is becoming desert all the time. Scientists may not be able to change the desert in time. Why is more and more land becoming desert? Scientists think that people make deserts. People are doing bad things to the earth. Some places on the earth don’t get much rain. But they still don’t become deserts. This is because some green plants are growing there. Small green plants and grass are very important to dry places. Plants don’t let the sun make the earth even drier. Plants don’t let the wind blow the dirt away. When a bit of rain falls, the plants hold the water. Without plants, the land can become desert more easily.
   A man decides to make a farm in a very dry place. He digs in the earth and takes away the grass and plants that are already growing on the dry land. He makes a farm. He puts plants in rows. The sun is very hot. It makes the land even drier. When the rain comes, it runs between the rows of plants. It washes the good dirt away. When the wind comes, it blows between the rows of plants. It blows the good dirt away. Soon the land is not good enough for a farm any more. The man lets his animals eat all the plants on it. Now the land does not have any plants on it. The sun and wind dry the land and all of the good dirt away. Now the land is a desert.
What’s the purpose of the writer to give an example of the man?
选项 A、To criticize him.
B、To tell an interesting story.
C、To prove that man makes deserts.
D、To prove the hot sun makes a desert.
答案C
解析 本文的写作目的是要提醒人们要认识到树木植物对于土壤的重要性，因为它们能够保持水分、不让风把土壤吹走，防止土壤沙漠化。因此，作者第二段的举例就是要证明一个事实，即：我们人类最终将土地沙漠化了。故选C项。
