122. (30985-!-item-!-188;#058&005940)

The features of the floor of the Kasei Valles on Mars look just like those at the base of Antarctic ice

streams, so it suggests that possibly it was flowing ice that carved the giant Martian channels

previously attributed to cataclysmic floods.    

(A) so it suggests that possibly it was flowing ice that

(B) a suggestion that flowing ice may have

(C) to suggest flowing ice as possibly having

(D) suggesting that flowing ice may have

(E) which is suggestive of flowing ice having possibly

A. it没有指代对象

B. a suggestion不能概括前句话的含义

C.
   不定式使用错误

D.
   正确。

E. Which没有指代对象；形容词be suggestive不及动词有效。

句子结构：The features of … look just like those (指代features) at…, suggesting…. 

前半句描述一个发现或者事实，后半句可以使用伴随状语、同位语等用法，说明该发现或事实的影响、

意义。此句使用的为伴随状语，如果要使用同位语，则为，The features of … look just like those (指

代features) at…, a finding/phenomenon/fact that suggests….

B. a suggestion不能概括前句话的含义，为甚么啊？

求教，谢谢

我发现后面有详解：

prep这样写道：

用抽象性名词充当同位语概括前句内容，再

接定语从句修饰同位语、进一步进行具体描述，是GMAT中常出现的句型。使用这种句型，要求

抽象性名词既可以概括前句内容，又可以充当从句的修饰对象。题目前半句描述的是一个事实，

可以用finding/phenomenon/fact等词来概括，但用suggestion概括不合适
