381.In his eagerness to find a city worthy of Priam, the German archaeologist Schliemann cut through Troy and uncovered a civilization a thousand years older as was the city Homer’s heroes knew.
(A) older as was the city Homer’s heroes knew
(B) more ancient than the city known to Homer’s heroes
(C) older than was the city known to Homer’s heroes
(D) more ancient of a city than Homer’s heroes knew（B）
(E) older of a city than was the one known to Homer’s heroes
正确答案是B，但是我想不通a civilization怎么能和city比呢...GMAC 不是在平行结构上一贯很严格的嘛，所以我想选E的说~虽然显得很awkawrd and wordy...

500.Many psychologists and sociologists now contend that the deliberate and even brutal aggression integral to some forms of competitive athletics increase the likelihood of imitative violence that erupts among crowds of spectators dominated by young adult males.
(A) increase the likelihood of imitative violence that erupts
(B) increase the likelihood that there will be an eruption of imitative violence
(C) increase the likelihood of imitative violence erupting
(D) increases the likelihood for imitative violence to erupt（E）
(E) increases the likelihood that imitative violence will erupt
请问选项D为什么错呢，是因为likelihood后面不能接for吗？总觉得从句没有介词修饰好啊...


517.Most nations regard their airspace as extending upward as high as an aircraft can fly; no specific altitude, however, has been officially recognized as a boundary.
(A) as extending
(B) as the extent
(C) to be an extent
(D) to be an extension（A）
(E) to extend

从固定搭配来看regard 后面跟as会比较好，但是一般不都是regard A as B, A和B是同词性的词吗？airspace 和extending放在一起怪怪的
题外话：复习了三天语法感觉好像比刚开始一脑袋浆糊要清楚多了，但是感觉一些常用的规律比如平行结构之类的虽然在排除选项的时候灰常好用，但是GMAC有时就喜欢故意把错选项摆成类似平行的结构来迷惑人，做到这种题目还真是纠结啊...不知道各位NN是在复习到什么阶段的时候练成的火眼金睛能看破各种陷阱的呢？
