Some people believe that town life is better than country life. I don’t agree with this. Town life can be convenient to us in many aspects. For example, you can move around easily, shopping can be more fun in a big shopping mall and you can enjoy a more colorful nightlife. But there are also many disadvantages. It is much nosier than in the country. Air pollution is more serious. It is not easy to park your car. It costs more to live in town. To name but a few is enough. Therefore, I prefer country life.
