(B) that had ?ourished at the sametime as had the civilizations
(C) that ?ourished at the sametime those had
(D) ?ourishing at thesame time as those did
(E) ?ourishing at thesame time as those were
NNS~我有两个问题,
第一个是?ourished是什么意思呀?我查了词典都没查到
第二个是,A我总觉得有点问题,我觉得前面有个?ourished,后面为了平行,划线句子后面应该加个did啊,如果不加那我觉得句子应该是这样:the site of an ancient civilization which is the same as the civilizations in the Nile Delta and the river valleys of the Tigris and Euphrates.求解释~
