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 Tigris and Euphrates.
a. same
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
“by the way, if you WERE going to include "did", preferred usage conventions actually place it BEFORE its subject: "...as did the civilizations in the nile delta..."one would never speak this way, but it's the best way to write these sorts of constructions in formal usage.”
francis ran faster than xavier. francis ran faster than xavier ran. francis ran faster than did xavier. francis ran faster than xavier did.
all parallel. the repetition in the second one would likely be considered fairly awkward, though; that's the point of replacing "ran" with the helping verb "did" in the third and fourth examples.”
我又困惑起来． 如果说第三个和第四个例子都是正确的，那么OG12-85的D选项为什么不对呢.
求高人指教.

重新看回这道题
还是不是很清楚用do来替代前句动词的具体依据
但是选项D的错误 貌似是因为flourishing 和 did 不构成平行关系作者: Jagabee 时间: 2015-3-19 08:02
如果选项D 是 that flourished at the same time as the civilizations did
