以a car pool(拼车)为话题的一篇英语作文

Nowadays ,there are more and more people owning private cars.On the one hand,some wealthy people who either are the boss of the private company or the white-collar managers in big companies have their private cars.On the other hand,some young people who are future-minded buy private cars ahead of their income by loans from banks.
　　Is it a good or bad thing to have a private car?Just as a coin has two sides ,so there are both advantages and disadvantages of having a private car.So far as its advantages are concerned,there are two examples for this.First ,it plays a very important part in providing its owner with convenience,enabling the owner to go where he wants to quickly and easily.Second,it can help its owner to save a lot of time which may be wasted by waiting for other vehicles.However,it also has its disadvantages .For one thing,it will have a negative effect on both the crowded traffic system and the environment in the long run.For another,it places burden on the public utility in providing more parking lots.
　　In short ,owning a private car has both its advantages and disadvantages.It is advisable that we should pay much attention to the environmental protection by not having a private car if we have little or no practical use of the private car.
