第28题: [多项选择]Private Cars in China
1.中国人拥有私家车的现状。
2.你对中国人拥有私家车所持的观点，
3. 解决的办法。
参考答案:
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 improved 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, automobiles consume 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 cannot 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 that 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.
