正确答案：How to Solve the Problem of Heavy TrafficIn recent years many cities are faced with the problem of heavy traffic. People have to waste more time on their way home or to work and even might be involved in an accident. With the development of industry and population expansion this problem becomes more and more serious.One solution is to lay down more roads. The solution has many advantages. For example it can efficiently decrease the number of houses and trucks in many main streets. But it will take up so much land that crowded cities become more crowded. Another solution is to open up more bus lines. If more bus lines should be opened up the number of bicycles and cars in the main streets would be greatly decreased. But the disadvantage of this solution is that many people wouldn't feel so convenient as they used to.In my opinion the right solution to the problem is the combination of the above two that is to lay down more roads in spacious areas and to open up more bus lines in downtown areas.
