　　Limiting tbe Buying of Cars or Not?
　　Beijing has placed strict restriction on the number of newly purchased car in the city and the policy bas sparked heated discussion. Some people support the policy, saying it，s a powerful method to cope with the severe traffic congestion in the capital. With cars increasing drastically in the past few years, severe traffic jams occur not only in rush hours but at any time of the day now.
　　Others, however, aie strongly against the limitations. They argue that the great number of official cars，which are frequently used, is a big factor causing traffic congestion. But the policy mainly aims at private cars and has no dear restrictions on the use of official cars. Besides, car purchase limitation would hinder the development of China's automobile industry，and more people would lose their jobs as a result.
　　Personally, I think the restriction of buying and use of cars, official cars incladed, is inevitable and just a matter of time for Beijing. If the number of cars is not limited, there will be a huge disaster for the environment, road resources, the travel demands of normal people and the improvement of living standards
