【题目】缺词填空

S【3】, in many places of the world, men don’t know the third of these is the most important. They just want to make money from the trees. Some people cut down a large n【4】of trees in the forests. Usually they are too busy c【5】down trees to plant and look after new trees so the forests slowly b【6】smaller and smaller.

This does not only m【7】that men will have fewer trees. The r【8】are even more serious. For where there are trees, their roots can prevent the rain from w【9】away the soil, but if there are no trees, the rain falls on hard ground and wash away the rich top-soil (地表土). When the top-soil is gone, n【10】remains but death.
