If you travel by air across the centre (中部) of Africa or South America, you fly over forests (森林) for thousands of kilometers. These great forests are the oceans (海洋) of trees. They are full of thousands of kinds of plants and animals.
However, the world’s forests are getting smaller and smaller all the time. We are cutting down the trees because we need wood, and we need more farmland. Some people say that there will not be any forests like these in 20 or 30 years. What will happen if they disappear?
If we cut down our forests a lot of plants and animals will disappear from the world. In a lot of places the new farmland will soon look like the old deserts (沙漠). Crops will not grow there. It will not rain very often and the weather will get very hot. Perhaps the climate (气候) of the world will change. This will be dangerous for everyone in the world. That is why we must take care of our forests.
The passage mainly tells us about ______ .
选项
A、Africa and South America
B、the result of cutting down the trees
C、the reasons for cutting down the trees
答案
B
解析
本文主要是说明砍伐森林造成的后果。
