标题: 不甚感激~~OG12 70
His studies of ice-polished rocks in his Alpine homeland, far outside the range of present-day glaciers, led Louis Agassiz in 1837 to propose the concept of an age in which great ice sheets had existed in now currently temperate areas.(A) in which great ice sheets had existed in now currently temperate areas
(B) in which great ice sheets existed in what are now temperate areas
(C) when great ice sheets existed where there were areas now temperate
(D) when great ice sheets had existed in current temperate areas
(E) when great ice sheets existed in areas now that are temperate

各位大N们，请问一下，为什么这道题不用过去完成时？OG答案还专门把过去完成时改成一般过去时~~但icesheet exist 是发生在 propose the concept 之前的呀？

用过去完成时必须要强调时间上的对比么？

如果文中有明确的时间暗示的时候

我刚才看这个题门突然有个问题转不过弯了，就是这里面in which great ice sheets existed in what are now temperate areas。里面的in which 究竟指代什么，如果把句子变成陈述句应该是什么？那不是有两个IN 了。有没有人回答一下这个问题？多谢

完成时的使用是要非常谨慎的，除非有关键词和时间上的对比，否则尽量不用完成时

in which是指in an age

这个In which 不算倒装把？

作者: wenchang 时间: 2010-10-13 11:31
这句话就是 in that age great ice sheets existed in what are now temperate areas

多谢，可能我给弄混了，记忆里介词+which怎么倒装的形式啊！糨糊了

我对D项的解释有疑问，为什么说“in current temperate areas is unclear” 啊？
如果把current变成currently，还会unclear吗？

用currently 修饰temperate阿~
