c里面的which指代有问题。

gone virtually unregulated 的逻辑主语是什么呢

dreamroad · 发表于 2009-11-26 21:48:24

which不就是指chemical pollutants吗？

同2楼，which就近指代time

楼上都是牛人啊！明白了

这是PREP旧版1里面的97题，楼主自己去看prep笔记吧，which本来就是一个很矛盾的问题，在which的就近指代问题上，OG里面很多都是自相矛盾的，所以我觉得which的问题是一个相对性问题而不是绝对性的语法错误，不能仅仅因为which就排除C。况且which在这里是因为他的泛指错了，而不是因为他的就近指代错了。

which这里是想指代前面整个句子，这样是错的。不是就近指代time的问题，抱歉我没说清楚。

have gone virtually unregulated 是什么意思呢? 这道题我也不明白。而且，A错在哪里的呢？还有，根据答案看来while在这里并不表明前后语句的并列，那while什么时候是平行结构的标志，什么时候不是呢（比如说这道题，while前后两句的时态并不是并列的）？
