　　Family Cars in China

　　With the development of car industry and the improvement of the people’s living standard in China, more and more cars are going into Chinese families. Some families have cars made in China, and others own cars imported from abroad. They drive them either to work or for holidays.

　　Cars have quite a number of advantages. It is very convenient to travel by cars, and this saves a lot of time. As a means of transportation easy to handle, family cars can carry not only people, but also goods. They can go almost anywhere owing to their small size. That’s why more and more families are trying to buy them.

　　However, just as a coin has two sides, cars also have some disadvantages. They cost the owners a lot of money for the fuel, insurance and maintenance; they are responsible for air pollution; and what’s more, car accidents kill hundreds of people each year and traffic jams happen very often. All these cause us many problems. Therefore, we should work out some ways to solve them.
