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. 

近年来，许多城市都面临着交通拥挤这个问题。人们在上班或回家的路上不得不浪费许多宝贵的时间，甚至还会出车祸。随着工业的发展和人口的增长，这个问题变得越来越严重。 

解决这个问题的一个办法是修建更多的道路。这一方法有许多好处。譬如，它可以有效地减少许多干线上的汽车和卡车的流量。但是这种方法也会占有许多土地，使本来拥挤的城市变得更拥挤。另外一种方法是多开辟公共汽车线路，这样，干线上的自行车和汽车的数量会大大减少。但这样做的弊病是许多人会觉得不像原来那样方便。

依我看，好的解决办法是二者结合，就是在宽阔的地区多修路而在闹市区要多开辟公共汽车线路。
