实际上，地球上的水非常有限。随着人口的快速增长和工业的快速发展，水的需求比以往更加迫切。同时，每天都有大量的水被污染和浪费。中国一些大城市已经面临着缺水问题。在那里，供水受到控制，工业受到限制。

我们应该怎么做？我认为，首先，应该使人们了解水的真实情况。每个人都应自觉地节约用水，并应制定某些法律禁止任何水被污染。我们必须保护现有的水资源并开发新的水资源。这样，我相信未来我们的城市将不再缺水。

Private Cars in China

　Private cars，in most developed countries，used to be the counterpart of bicycles in China. Nevertheless，more and more Chinese people have cars of their own nowadays. It is an indication of the lifted living standard of Chinese people. But in my opinion，private ownership of cars should not be encouraged in China.

　There are sound reasons for the limitation of private cars in China. First，it is self evident that the automobile contributes much to air pollution. In China，especially in large cities whose residents are more likely to buy private cars，the pollution of the air is already very serious. More private cars will inevitably aggravate the present situation. Second，private cars can be a formidable threat to the traffic. To tell the truth，today many people can afford a car，if a large number of private cars rush onto the streets，the already dense traffic will suffer more. Last but not the least，the automobile consumes energy. We always proudly claim our country is rich in natural resources. But in the mean time，we need to remember we also have a large population. We do have rich resources of energy，but speaking of energy，we can not smile with ease.

　Therefore，I sincerely believe that private cars should be discouraged in China. Then，by what means shall we limit private cars？Since people buy private cars mainly for convenience，my first suggestion is to develop adequate public transportation which is effective and punctual. At the same time，we should raise the price of gasoline to a prohibitive level so as to make car－driving expensive enough. All in all，private cars，from my point of view，should be limited in China.

中国的私家车

在大多数发达国家，私家车曾经相当于中国的自行车。然而，现在越来越多的中国人拥有自己的汽车。这是中国人民生活水平提高的一个标志。但是在我看来，中国不应该鼓励私人拥有汽车。

中国对私家车的限制有充分的理由。首先，汽车造成空气污染是不证自明的。在中国，特别是在大城市，那里的居民更有可能购买私家车，空气污染已经非常严重。越来越多的私家车将不可避免地使现状恶化。其次，私家车对交通是一个可怕的威胁。说实话，今天很多人都买得起汽车，如果大量的私家车涌上街头，本已拥挤的交通将受到更大的影响。最后但并非最不重要的，汽车消耗能源。我们总是自豪地宣称我们国家自然资源丰富。但与此同时，我们需要记住，我们也有一个庞大的人口。我们有丰富的能源资源，但谈到能源，我们不能轻松地微笑。

因此，我真诚地认为在中国应该禁止私家车。既然人们购买私家车主要是为了方便，我的第一个建议就是发展足够的有效且准时的公共交通。与此同时，我们应该提高汽油的价格到一个令人望而却步的水平，以使驾驶汽车足够昂贵。总之，在我看来，中国应该限制私家车。
