盗版问题(Heavy Traffic)

　　in recent years ninny 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 acci dent. 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 ex ample, it can efficiently decrease the number of buses and trucks in many main streets. but it will take up so much land that crowded cities become more crowded. another solu tion is to open up more bus lines. if more bus lines should be opened up,the number of bicles 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 os they used to.

　　in my opinion, the right solution to the problem is the combination of the two, thatis, to lay down more roads in spacious areas and to open up more bus lines in downtown.
