7月7日雅思大作文真题 | 建更多铁路和地铁好，还是修扩更多道路( 八 ) 建更多铁路和地铁好

. The subway, for example, can
deliver
more than 10,000 people in as short as half an hour, who, if all travel by buses or cars, will pose
tremendous
pressure to the traffic. However, though causing less pollution, it is pretty costly and time-consuming
to build a new train and subway line. The city dwellers
will often have to endure
a few years’ traffic inconveniences before they can enjoy the benefits that a new train and subway line brings to them.

很明显，铁路和地铁线路的载客量比道路要多，特别是在一段给定时间内，因此在减少高峰时期的交通方面是十分有效的。例如，地铁可以在短短半小时内运送1万多人，如果这1万多人都乘公共汽车或汽车出行，将对交通造成巨大的压力。然而，尽管污染更少，建造一条新的火车和地铁线路是非常昂贵和耗时的。城市居民常常要忍受几年的交通不便，才能享受到新的火车和地铁线路给他们带来的好处。
