For years the beautiful R buiding in P市区 have been damaged by exhaust from the many tour buses that come to the city. There has been little parking space, so most buses have idled at the curb during each stop on their tour. 为了减少污染， Ｐ市区打算提供一个parking space that accommodate1/3 of the tour buses. So damage to P's buildings will decline significantly.
问下列哪句话最能SUPPORT这个停车区的作用(减少对大楼破坏)
我选择的是:除了发动机的EXHAUST,其他东西不太对大楼造成破坏.
答案是: Tour buses typically spend less than 1/4 of the time they are in P city transporting passengers from one site to another.
不太理解正确答案,为什么啊?请各位大虾帮帮我吧~~~~~~3KU !
我觉得是这样理解，文中没有提到发动机 主要是讲污染问题。
如果buse只有1/4时间是用于正途－接送旅客，那么3/4时间都是在街上晃（因为没有停车位），这样说明了停车位的重要性，车都有地方停了就不会造成污染了。
