绿化我们的城市(Make Our Cities Greener)
Many things have been done and great progress has been made in the greenization of our cities in recent years.Many trees have been planted and much care has been taken of the planted trees.But,in spite of all this,greenization in the cities in China is far from satisfactory compared with cities in other countries in the world.For example,the green space for every people in Shanghai is only 2 square meters while that of the people in London exceeds 20 square meters.
We can benefit much from the greenization of our cities.First,trees absorb carbon dioxide which is harmful,but produce oxygen which is essential to human beings.Secondly,with trees all around,our cities will look more beautiful.Thirdly,trees can improve the climate of the cities,making it neither too hot in summer nor too cold in winter.
Since we can get so much benefit from making our cities greener,we should spare no effort to do so.We should plant even more trees and take even better care of them while they are growing.Besides,we should not cut down trees any more.In a word,we should do everything to add to the greenization of our cities.
Deserts Are Expanding(沙漠正在蔓延)
沙漠正在蔓延(Deserts Are Expanding)
There are vast areas of land on every continent where there is no rainfall or vegetation.It is estimated that more than 40 per cent of the land on the earth's surface is desert or desert-like.What is worse,these deserts are spreading at a surprising rate every year.If this trend continues,sand will bury almost everything in the near future.
Two reasons account for the fact that deserts are spreading.The first reason comes from nature.These areas are usually located in the far inner land where rainfall can never reach.The second reason comes from man himself.Many people regard immediate profit as a supreme value,which results in over-grazing,poor farming,tree cutting,and strip mining.All these activities leave land unprotected.Consequently,rain water washes away topsoil into rivers and oceans,wind blows away loose soil.
The expansion of deserts must be stopped if we are to survive on this planet.Man can make deserts,he can also prevent them from spreading.Stopping over grazing,poor farming,tree cutting,and strip-mining is the first step.Planting a green belt of trees along the edge of deserts is the second step.Covering the deserts with vegetation is another step.We hope man can make great efforts to develop better ways to bring the spreading deserts under control.

绿化我们的城市（使我们的城市更绿）
许多事情已经做了很大进展,并在我们的城市绿化近年来取得.许多树木已经种植的照顾一直是采取种植的树木.但是,尽管这一切,在中国的城市绿化是远远不能令人满意,与其他国家相比,城市在世界上.例如,在上海每个人的绿色空间只有2平方米,而在伦敦的人超过20平方米.
我们可以从中受益很大,我们的城市绿化.首先,树木吸收二氧化碳,是有害的,但产生的氧气是人体必需的.第二,四周的树木,我们的城市会显得更加美丽.第三,树木可以改善城市气候,使得它既不太热,夏无过于寒冷的冬季.
既然我们可以从我们的城市绿化作出这么多的好处,我们应该不遗余力地这样做.我们应该种更多的树,甚至采取更照顾他们,而他们正在成长.此外,我们不应该砍伐树木了.总之,我们应该尽一切努力增加了我们的城市绿化.
沙漠正在扩大（沙漠正在蔓延）
沙漠正在蔓延（沙漠正在扩大）
有大面积的土地上每个大陆在没有降雨或植被.据估计,超过了对地球表面的百分之四十的土地是沙漠或沙漠状.更糟糕的是,这些沙漠正在以惊人速度蔓延,每年.如果这种趋势继续下去,沙埋,几乎将在不久的未来的一切.
有两个原因解释的事实,沙漠正在蔓延.第一个原因来自于大自然.这些地区通常位于内陆的降雨量远不能达到.第二个原因来自于人类自己.许多人认为一个最高值,在过度放牧,落后的耕作,林木采伐和带材的挖掘结果眼前利益.所有这些活动给土地得不到保护.因此,雨水冲走流入河流和海洋,风吹走表土疏松土壤.
沙漠扩张的势头必须予以制止,如果我们要生存在这个星球上.人可以使沙漠,他还可以防止蔓延.过度放牧,落后的耕作,林木采伐和带开采停止是第一步.种植沿沙漠边缘的树木绿化带是第二个步骤.沙漠植被覆盖的另外一个步骤.我们希望他能取得巨大的努力,开发出更好的方法来控制沙漠的蔓延.
