Cars and Air Pollution
Too many cars have created a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. All the time，they are releasing huge amounts of waste gases into the atmosphere. These gases are very harmful, causing diseases and even death.
太多的汽車已經給我們的`世界製造了許多嚴重的問題。除了堵車、事故和快速的燃料消耗之外，汽車對大城市的空氣污染有很大一部分責任。一直以來，汽車向大氣中釋放大量的廢氣。這些氣體非常有害，會導致疾病甚至死亡。
So serious is the problem that we must find some solutions to it. One possible solution is to design and develop clean cars and clean fuels. In
Shanghai, some of the public buses begin to run on natural gas， which does not give off as much carbon dioxide as petrol. But it may take decades for the new models of clean cars to complete1y replace the traditional ones. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and environment enough, most people will not buy private cars. And the total number of cars in big cities will reduce greatly.
問題如此嚴峻，我們必須找到一些解決方法。一種可能的解決方法就是設計和研發清潔汽車和清潔燃料。在上海，一些公交車開始使用天然氣，天然氣不像汽油那樣釋放那麼多二氧化碳。但是，要使新型的清潔汽車完全替代傳統汽車，可能需要幾十年的時間。另一個解決方法是發展現代公共交通系統，限制私家車的使用。如果石油價格持續上漲，公交車變得有效率且足夠環保，那麼大部分人就不會買私家車了。而大城市汽車的總數會大大減少。
On the whole, with the collective efforts of all parts concemed, the elimination of air pollution caused by cars will be solved in the near future.
總之， 有了所有相關方面的共同努力，消除由汽車造成的空氣污染問題會在不遠的將來得到解決。
