请教一道困惑以久的 OG-80

80.   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（A）

(E) flourishing at the same time as those were

请问各位高手，the same -----as----这样的搭配中，as的后面不是应该接完整的句子吗？我见到有的语法书中这样解释这种固定搭配，把as 看成是一个宾语从句，其先行词是the same 后面的名词。如果这样的解释可以的话， 应该选B， 虽然用的过去完成时。

出自旺旺英语：As 的用法
例1. the same… as；such…as 中的as 是一种固定结构, 和……一样……。
　　 I have got into the same trouble as he (has).
例2。托福题：MEADOWLARKS ARE ABOUT THE SAME SIZE as ROBINS, THEY HAVE HEAVIER BODIES, SHORTER TAILS, AND LONGER BILLS. (89.5)

例3。四级考题。Melted iron is poured into the mixer much ____ tea is poured into a cup from a teapot. (1996.6)

A.in the same way like 　　B.in the same way which

C.in the same way 　　D.in the same way as

例四。1370 King Charles V of France decrees that all Paris church bells must ring at the same time as the Royal Palace，……

例1还是一个宾语从句，例2 as 后就是一个表语丛菊了。例3是个状语丛菊。例四更是印证在 the same...as 结构中，关键不在于as引导什么丛菊，关键在于引导一个对等结构。一家之拙见。

谢谢各位的帮助。我把the same as 和 as--- as----混了。
