英语翻译
Trees are useful to man in three very important ways:they provide him with wood and other products;they give him shade and they helo to prevent drought and floods.Unfortunately,in many parts of the world,in his eagerness to draw quick benefit from the tress.man has cut down a large number of trees.Even where a government realizes the improtance of plentiful supply of trees,it is difficult for it to persuade the villagers to see this.So unless the government has a great system of control,or can educate the people,the forests slowly disappear.
The results are more serious;for where there are trees their roots break the soil up allowing the rain to sink and also hold the soil.thus preventing it from being washed away easily,but where there are no trees.the soil becomes hard and poor.
The rain falls on hard ground and flows away on the surface,causing floods ,and carry away with it.the rich topsoil in which crops grow so well when all the topsoil is gone,nothing remains but worthless desert.

树木对人类来讲有三大好处：树木可以做木材和提供其他产品；提供树荫,减少旱涝灾害；不幸得是,在世界上的许多地方,人类为了更快地从树木那里获益,砍伐了大量的树木.即使政府已经意识到了充足树木的重要性,但很难让村民认识到这一点.所以,除非政府采取有效的控制措施,或能够教育人民,森林仍然会缓慢地消失掉.后果会更严重,因为有树的地方,树的根会深入土壤,让雨水渗入其中,并抓牢土壤,以防止土壤被雨水轻易地冲刷走；而没有树的地方,土地会坚硬而且贫瘠.
雨落在坚硬地面上,会从表面流走,造成洪水,并带走表面的土壤.肥沃的可以供作物生长的表层土壤被冲走以后,就只剩下了一无所有的沙漠.
