●原因1:公共交通能更加有效的缓解交通阻塞(relieve traffic congestion more efficiently)
------相比投钱在修路上,投资公共交通,例如地铁或者公交车(subway or buses)能承载更多的乘客(carry more passengers), 大大减少私家车的使用(reduce the use of private vehicles),交通变的更加通畅(become smoother)
●原因2:公共交通更加环保(more environmentally friendly)
------投资公共交通,更多的人可以选择公共交通出行而不是私家车(more people travel by public transport rather than private cars),减少废气排放(decline the emission of exhaust gases),空气质量提高(improve air quality)
Body 3:
●原因1:投资道路能缓解交通阻塞(widen roads can ease traffic jams)
------建造更多的道路(build more roads),或者拓宽车道(widen the lanes),车辆可以分流(divert traffic),车辆有更多的行驶空间(more space to travel),有效的缓解了交通压力(effectively alleviate traffic pressure)
●反驳: 修建和扩宽道路会增加道路上行驶的车辆(increase vehicles travelling on the roads),交通阻塞会更加严重(will be worsened), 同时,空气污染也会加重(air pollution will be aggravated)
