高考英語閱讀專題強化練習譯文
樹木對于人來說有3個重要益處：樹木給人類提供木材和其他產物;樹木可以讓人們乘涼;樹木可有效地防止旱澇災害。
可惜的是，在世界上許多地方，人類沒有認識到以上三個作用中，第三個是最重要的。人們急切于從樹木上快速的謀取利益，于是大量的砍伐森林。
兩千年之前，有一個富裕和強大的國家。為了建立帝國，砍倒了樹木來造戰艦。帝國建立了，但是，沒有樹木的土地變得荒蕪和貧瘠。當帝國四分五裂的時候，整個國家發覺自己面臨的是水災和饑荒。 就算在政府認識到足夠的樹木儲備的重要性時，有時卻很難讓人民也意識到這點。人們砍倒了樹木，卻疏于種植和照料樹苗。因此，除非政府建立一套體制來控制或者教育人們，否則森林就會漸漸消失。
森林的消失不僅僅意味著樹木的減少，還有更嚴重的后果。在有樹的地方，樹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。但是在沒有書的地方，雨水直接落在堅硬的地面，在土地表面流走。這不僅會導致洪水，雨水還會帶走莊稼賴于生長的肥沃的表層土。當所有的表層土被沖走之后，除了毫無價值的沙漠之外，什么也沒有了。
