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. B that had flourished at the same time as had the ciivlizations C that flourished at the same time those had D flourishing at the same time as those did E flourshing at the same time as those were 答案是A,是不是省略了did这个动词? ets有时代词、动词之类的可省略,有时不可省略,我都胡涂了!请各位牛人指教!
这道题可以用排除法搞定,而且好像我有一种感觉就是这里的就是不要加did的,因为that flourished at the same time as the civilizations是修饰成分,如果句子换成 civilization flourished at the same time as did the civilizations of ...那么这个did就不能省了。
