题目

SAT
In 1968 air pollution from automobile exhaust,particularly (like that in the Los Angeles environs,became of an increasingly more urgent) concern to envirnonmentalists.
of the sort found in the Los Angeles area,became an increasingly urgent.
为什么答案比原句好呢?

答案

1英文没有"become of" 这种说法,考的可能是想让你跟because of 搞混吧.
2Increasingly 是更加,更多的意思,而more也是,因此意思重复,用其中1个就好了.
3That 指代对象不明确,of the sort 就清楚了说明是 the sort from automobile exhaust.
这3个应该是最主要的原因了
