我刚刚也跟LZ问了差不多的一个题目, 这里给你分享一下 Industrializaition and modern methods of insect control have improved the standard of living around the globe while at the same time introducing some 100,000 dangerous chemical pollutants that have gone virtually unregulated since they were developed more than 50 years ago.

while at the same time后面的东西和have improved平行,having最后做伴随状语。
虽然我这一点上还是想不明白,为什么这里while at the same time不需要考虑平行,但是我这个题目的笔记写着: 用了sb do...while doing的结构,省掉了they
如果(B)改为 they denounce big government--they say that government is doing too much and has become too powerful--but supporting at the same time。这样正确吗?
换个言之, they denounce big government--they say that government is doing too much and has become too powerful--but they support at the same time。这样肯定是正确的吧。。。
