　　 阅读下面的短文，然后按要求写一篇150词左右的英语短文。

　　Trees are useful

　　Trees are useful to man in three important ways:they provide him with wood and other products,they give him shade,and they help to prevent droughts and floods.Unfortunately,in many parts of the world man has cut down a large number of trees every year.Even where the government realizes the importance of trees,it is difficult to persuade the villagers to see this.So unless the government can educate its people and exercise effective control,forest will disappear.

　　The results are serious:for where there are trees their roots break the soil up to allow 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 the hard ground and flows away on the surface,causing floods to carry away the nice topsoil.When all the topsoil is gone,nothing remains but worthless desert. 写作内容 1.以约30个词概括短文的要点。 2.发表你的看法,提出几条如何保护树木的建议并解释理由,至少包含以下内容要点,该部分的字数大约120词左右。 (1)通过教育手段让孩子们从小就有环保意识。 (2)通过法律手段对成年人的砍伐行为进行管制。 (3)通过传授致富知识,帮助贫穷地区发展其他农业,缩小地区间贫富的差距。 写作要求 可以使用实例或其它论述方法支持你的论点，也可以参照阅读材料的内容，但不得直接引用原文中的句子。

　　The passage tells us trees play an important role for human beings.However,because people don，t see the importance of protecting them,lots of trees have been cut down,which have caused serious results.

　　So we should take a series of effective measures to cope with the situation.For one thing,we should educate children even in the kindergartens.It is necessary for a person to form a good habit of environmental protection from his childhood.For another thing,laws should be made to prevent people from cutting trees.Of course,it is also important to let adults gain some knowledge of environmental protection.Finally,we can help them shake off poverty by teaching them modern technology on the farming or raising poultry,thus making the wide gap between the rich and the poor small.

　　Personally,I believe that only when people realize the importance of trees and do something to protect them will we be able to enjoy a greener world.I do hope these measures can help solve the problem. 高考总复习·人教版·英语
