【正确答案】On Carpooling It is not an uncommon social phenomenon that many people choose to carpool these days, especially among young office workers. They travel together to work in one car and share the cost. However, concerning this phenomenon, opinions vary from person to person. Some people hold that carpooling is a good idea because it's environmentally friendly and economical. By carpooling, the number of cars on the road is reduced, so is the petrol consumed and the exhaust fumes emitted by cars. The traffic congestion can also be alleviated. At the same time, thanks to their sharing of the cost of cars, both the car-owners and their partners can save money. Consequently, carpooling is becoming more and more prevalent. But others maintain that carpooling is not safe. They argue that if traffic accidents happen, the interests of people who take others' cars cannot be protected for lack of relevant laws about carpooling at the moment. And the owners of cars can be suspected of illegal transport business. From my point of view, the advantages of carpooling outweigh its disadvantages. It is in accord with our policy of constructing a conservation-oriented society. Its disadvantages can be overcome through more perfect regulations established by the government.
