that flourished at the same time as the civilizations in the Nile Delta and the river valleys of the Tigris and Euphrates
在做题时,定语从句是可以从主句分开出来,看成单独的一句话的。将an ancient civilization替换that做整个句子的主语,变成如下:
an ancient civilization flourished at the same time as the civilizations in the Nile Delta and the river valleys of the Tigris and Euphrates
这样逻辑就很清晰,是一个典型的比较对象是主语的比较结构。在比较主语时,than后面可以补上助动词,也可以不补,但是补上更好,为了这强调这两个事物之间同一动作的比较

前辈,又看加你了~这个能不能像楼主之前理解的那样,that flourished作为定语不考虑,at the same time as是比较短语,那就是an ancient civilization 和the civilization比较,这样很对称啊
