答案 According to one recent survey, the number of private cars in Beijing has increased by 20% to 2 million and it is difficult to foresee any downward trend. This ever-swelling car ownership in many big cities as well as countryside is causing numerous problems. Most people often point to the severe traffic congestion in metropolises like Beijing and Shanghai. The soaring number of cars is not matched by a corresponding increase in the road systems with better design. So during the rush hours in the morning and afternoon, main roads of these big cities are crowded with various cars, sometimes becoming super parking areas. These jams are very costly in terms of both time and money and terribly reduce the efficiency of the city. However, the most serious problem of unlimited car use is the pollution caused. Cars emit various waste gases and dusts, mainly CO, and C02. These greenhouse gases are greatly contributing to the global warming. According to a research by European scientists, carbon emissions from vehicles rose by 25% in the last decade, far outpacing the increase rate of other sources. If we do not control vehicle use or endeavor to make it greener, the outcome awaiting us would be rather gloomy or even disastrous. As a result, I am of the opinion that car use should be reasonably discouraged. For example, the government can increase the tax on cars with large emissions and subsidize the public transportation to lower their prices and improve their condition, thus encouraging increasingly more people to choose public transports such as tubes or buses. Of course, we are not advocating a total ban of car use, which is actually unrealistic and unjustifiable. Personally, I think that a policy like the "odd-even" traffic restriction employed by Beijing during the Olympic Games may serve as a good strategy.
