英语翻译
Trees are useful to men in three important ways:they give them with wood and other products,they give them shade,and they help to prevent drought (干旱) and floods (水灾).
Unfortunately,in many parts of the world,men have not known that the third of these left trees are the most important.In their eagerness (渴望) of making money from trees,some people have cut trees down in large numbers,only to find that without them they have lost the best friends they had.And besides,they are usually too careless to plant and look after new trees,so the forests slowly become smaller and smaller.
This does not only mean that men will have fewer trees.The results are even more serious:for where there are trees,their roots(根)break up soil-allowing the rain to sink in-and also bind(固定)the soil,thus preventing it from being washed away easily,but where there are no trees,the rain falls on hard ground and flows away,causing floods and carrying away the rich top-soil (地表土).When all the top-soil is gone,nothing remains(剩下)but desert.
英语翻译Trees are useful to men in three important ways:they giv
树木对人们很有用表现在三个方面:他们给我们木头和其他木制品,他们提供阴凉,他们帮助我们远离干旱和水灾.
不幸的是,在世界的很多地方,人们并不知道第三个用途的重要性,他们渴望用树木赚取金钱,一些人大面积的砍倒树木,最后才发现他们已经丢失了曾经他们最好的朋友,初次,他们对新的树木的照顾很马虎,因此,森林变得越来越小.
这并不意味着人们只是少了一些树木.后果通常更加严峻.在有树木的地方,树木的跟固定住土壤防止雨水冲刷而流失泥土,这样就防止了泥土呗轻易的冲刷走,但在没有树木的地方,雨水冲刷着坚硬的土地最终把泥土冲刷走,造成了肥沃泥土被冲刷走的状况,当所有的好的土质被冲刷走了,除了沙漠没有其他留下
大概就这个意思
