【正确答案】Private Cars in China
   More and more Chinese people have cars of their own nowadays. It is an indication of the improved living standard of Chinese people. But in my opinion, private ownership of cars should be discouraged 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 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 least, automobiles consume energy. We always proudly claim our country is rich in natural resources. But in the meantime, we need to remember that 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 not be encouraged 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 that is efficient 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.
