中翻英.答得好,
（1）水--20亿人生命之所
2005年6月5日是联合国确定的第33个世界环境日,水是生命赖以生存的载体,它孕育了地球上的一切生物,也是人类延续和发展的必要条件.联合国环境规划署提醒公众关注全球共有20亿人严重缺水的严峻现实,呼唤人类关注日益严重的水危机.中国是全球13个人均水资源最贫乏国家之一,人均拥有淡水量还不到世界人均水量的1/4,让我们珍惜每一滴水.节约用水光荣!
（2）汽车尾气中有哪些主要污染物
汽车排放污染物90%来自与汽车排气尾管排出的废气,主要是由于汽车燃料燃烧不完全所致.主要成分为一氧化碳,碳氢化合物,氮氧化物,二氧化碳,铅,微粒等.其 中碳氢化合物中成分复杂,有刺激人眼的醛类化合物,有以知为强烈致癌物质3,4-苯并蓖等.另外20%污染物分别来自于汽车曲轴箱废气和供油系统泄露,这部分污染物主要为碳氢化合物.
（3）地球的未来
第二段可以不翻
（4）汽车排放污染物90%来自与汽车排气尾管排出的废气,主要是由于汽车燃料燃烧不完全所致.主要成分为一氧化碳,碳氢化合物,氮氧化物,二氧化碳,铅,微粒等.对人体危害极大,所以,要少开车,多骑车.保护自然,从我做起.

(1) water--2,000,000,000 person of lives the 2005 year June 5 is the United Nations definite 33rd world environment date, the water is the life livelihood carrier, it has bred on Earth's all living thing, is also the human extension and the development essential condition. The Environment Program reminder public attention whole world altogether has the stern reality which 2,000,000,000 people seriously water scarcity, summons the humanity to pay attention to day by day the serious water crisis. China is global one of 13 person even water resources most deficient countries, average per person has the fresh water quantity also world average per person water volume 1/4, lets us treasure each water drop. The economize on water is honorable! which main pollutant (does 2) in the automobile exhaust have the automobile emission pollutant 90% to come from the waste gas which discharges with to exhaust liner, is mainly because the automobile fuel combustion is the result of not completely. The principal constituent is the carbon monoxide, the hydrocarbon, the nitrogen oxide, the carbon dioxide, the lead, the particle and so on. And in the hydrocarbon the ingredient is complex, has the stimulation human eye aldehydes compound, has take knows as the intense carcinogen 3,4- benzene and bi and so on. Other 20% pollutant come from separately the automobile crank case waste gas and the oil supply system revelation, this part of pollutant are mainly the hydrocarbons. (3) Earth's future the question supplemented: The second section may not turn (4) the automobile emission pollutant 90% to come from the waste gas which discharges with to exhaust liner, is mainly because the automobile fuel combustion is the result of not completely. The principal constituent is the carbon monoxide, the hydrocarbon, the nitrogen oxide, the carbon dioxide, the lead, the particle and so on. Is enormous to the human body harm, therefore, must little drive, rides a bicycle. The protection nature, starts from me .
