Salt deposits and moisture threaten to destroy the Mohenjo-Daro excavation in Pakistan, the site of an ancient civilization that flourished at the same time as the civilizations in the Nile Delta and the river valleys of the Tigris and Euphrates.
Salt deposits and moisture threaten to destroy the Mohenjo-Daro excavation in Pakistan, the site of an ancient civilization that flourished at the same time as the civilizations in the Nile Delta and the river valleys of the Tigris and Euphrates.
(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
I suppose B is the proper answer in this case. the Mohenjo-Daro excavation in Pakistan and the site 应该是同位语。SITE应该是进一步说明EXCAVATION的。所以这里应该用过去完成时去形容发生过的事。
flourish仅仅发生在过去,用定语从句比较好。 B中的完成时没有必要。 DE中的分词表正在进行或者伴随,是不对的。 the same... as固定搭配,C错 关于正确答案A, 可以理解为:that flourished at the same time as (did) the civilizations.
