　　Topic:
　　Traffic is developing rapidly all round the world at present, what are the traffic problems in your country? What causes these problems? Make some recommendations.

　　Sample:
　　Transportation has been developing rapidly in recent years, especially in large cities. However, it must be admitted that, along with the benefits of the rapid development of urban traffic, it causes some certain problems. One of the biggest problems, in my opinion, is traffic jams in some heavily-populated cities. It has become common to see passengers and drivers having to wait in long lines of buses and cars moving at a snail’s pace on the streets during the rush hours.

　　There are several reasons for this problem. First, the number of vehicles is increasing much more rapidly than the building of roads. No sooner has a new road been completed and opened to public traffic than it is crowded with all kinds of vehicles. Second, there seem to be too many private cars and not enough public buses. In most cases, a car carries only one or two people, while it occupies almost half the space a bus does. Third, many people, including drivers, pedestrians and cyclists do not obey traffic rules properly, especially at busy intersections. And this undoubtedly worsens the already grave situation.

　　In view of the seriousness of this problem, effective measures must be taken before things get worse. On the one hand, the government should invest more money in the building of new roads and the repairing and maintenance of the old ones, particularly those in busy areas of the cities. On the other hand, the number of private cars in urban areas should be limited while the number of private cars in urban areas should be limited while the number of public buses should be increased. At the same time, it is essential that stricter traffic rules and regulations be issued to strengthen traffic control and facilitate the normal and efficient running of all means of transportation.

　　With such efforts made and persisted in, I am confident that it will not be long before city traffic in China flows in a smoother and more efficient manner.
