问题 Urban ______ could no doubt be relieved somewhat by a reduction in public transport fares.

选项 A、jamming
B、congestion
C、accumulation
D、blockage

答案B

解析 名词辨义。这四个选项的词性都是名词,其中jamming表示“干扰台,人为干扰”,congestion是指“交通堵塞”,如:In many big cities,congestion in the rush hour is so serious that taking a bus proves a dreaded ordeal.(在许多大城市里,高峰时的交通非常拥挤,这时乘公共汽车真是一场可怕的经历。) accumulation表示“积聚,堆积物”;blockage表示“阻塞;堵塞”,如:There’s a blockage in the pipe.(管道堵塞了。)根据句意,城市的交通堵塞可以缓解,应该选择B)。
