　　Car in Cities
　　Nowadays, people' s living standard has been improved greatly. Consequently, more and more people in big cities have their own cars, and there are still more people who are going to buy cars soon.
　　There are some advantages to have a car in big cities. Firstly, a car makes one arrange his transportation more freely. You can go out whenever you like. In addition, a car makes it easier and more comfortable for traveling. With a car, you do not need to wait for the bus in the icy cold in winter or under the burning sun in summer.
　　In spite of all these advantages, too many cars in big cities will cause some problems. First-ly, there may be more traffic jams since there are more and more cars. Secondly, more cars will lead to serious air pollution. Besides, parking will be a big problem since parking spaces in large cities are limited. All in all, if conditions permit, owning a car in big cities can make our work more efficient, and our life will become more pleasant as well. If we want to promote the use of cars, there is still a long way to go.
