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
OG 给的答案是A
答案A表达的是 X flourished at the same time as Y
可是从之前做过的那些题目看来 OG一直教导我们结构要平行 要agreement, 那直觉上正确的结构就应该是X flourished at the same time as Y did, 所以我搞不懂,求高手解答
谢谢
