A.that flourished at the same time as the civilizations B.that had flourished at the same time as had the civilizations C.that flourished at the same time those had D.flourishing at the same time as those did E.flourishing at the same time as those were
请问 为什么 A选项里不需要写 as the civilizations do??? or did ???!!! 不是说要平行的呢~~~1作者: jeffery2541 时间: 2012-6-1 23:23
首先可以很确定CDE全部错误，因为出现了those； 其次B的时态错误，不应该用过去完成时态，这里没有过去与过去的过去时间对比； 最后来说A，助动词的补出问题。因为主句只是一个主谓，而没有谓语的直接宾语，我们可以知道比较的就是主语，而不会误以为是比较宾语，不会产生歧义，所以，可以补出也可不补出。这样平行依然没有打破，同时也照顾到了简介原则。不是所有的平行都必须完全一模一样，比如说，不定式的平时，之后的to就可以省略。
