閱讀試題

Trees are useful to man in three very important ways：they provide him wood and other products;they give him shade;and they help to prevent drought(干旱)and floods.

Unfortunately，in many parts of the world，man has not realized that the third of these services is the most important.In his eagerness to draw quick profit from the trees，he has cut them down in large numbers Two thousand years ago，a rich and powerful country cut down its trees to build warships，with which to gain itself an empire It gained the empire but，without its trees，its soil became bare and poor.When the empire fell to pieces，the country found itself faced by floods and starvation.

Even where a government realizes the importance of a plentiful supply of trees，it is difficult sometimes to make the people realize this.They cut down the trees but are too careless to plant and look after new trees So，unless the government has a good system of control，or can educate the people，the forests slowly disappear

This does not only mean that there will be fewer trees.The results are even more serious：for where there are trees，their roots break the soil up，allowing the rain to sink in， and also bind the soil.This prevents the soil from being washed away.But where there are no trees，the rainfalls on hard ground and flows away on the surface，and this causes floods and the rain carries away the rich topsoil in which crops grow When a11 the topsoil is gone.nothing remains but worthless desert.

參考譯文

樹(shù)木對(duì)于人來(lái)說(shuō)有3個(gè)重要益處：樹(shù)木給人類(lèi)提供木材和其他產(chǎn)物;樹(shù)木可以讓人們乘涼;樹(shù)木可有效地防止旱澇災(zāi)害。

可惜的是，在世界上許多地方，人類(lèi)沒(méi)有認(rèn)識(shí)到以上三個(gè)作用中，第三個(gè)是最重要的。人們急切于從樹(shù)木上快速的謀取利益，于是大量的砍伐森林。

兩千年之前，有一個(gè)富裕和強(qiáng)大的國(guó)家。為了建立帝國(guó)，砍倒了樹(shù)木來(lái)造戰(zhàn)艦。帝國(guó)建立了，但是，沒(méi)有樹(shù)木的土地變得荒蕪和貧瘠。當(dāng)?shù)蹏?guó)四分五裂的時(shí)候，整個(gè)國(guó)家發(fā)覺(jué)自己面臨的是水災(zāi)和饑荒。 就算在政府認(rèn)識(shí)到足夠的樹(shù)木儲(chǔ)備的重要性時(shí)，有時(shí)卻很難讓人民也意識(shí)到這點(diǎn)。人們砍倒了樹(shù)木，卻疏于種植和照料樹(shù)苗。因此，除非政府建立一套體制來(lái)控制或者教育人們，否則森林就會(huì)漸漸消失。

森林的消失不僅僅意味著樹(shù)木的減少，還有更嚴(yán)重的后果。在有樹(shù)的地方，樹(shù)根不僅把土壤粉碎成小塊，便于雨水的滲入，還可以牢牢的抓住泥土，防止泥土被沖刷走。但是在沒(méi)有書(shū)的地方，雨水直接落在堅(jiān)硬的地面，在土地表面流走。這不僅會(huì)導(dǎo)致洪水，雨水還會(huì)帶走莊稼賴(lài)于生長(zhǎng)的肥沃的表層土。當(dāng)所有的表層土被沖走之后，除了毫無(wú)價(jià)值的沙漠之外，什么也沒(méi)有了。
