OG12 73 弱弱的问一下

浅吟天

73.Combining enormous physical strength with higher
intelligence, the Neanderthals appear as equipped for
facing any obstacle the environment could out in their
oath, but their relatively sudden disappearance during
the Paleolithic era indicates that an inability to adapt
to some environmental change led to their extinction.



(A)appear as equipped for facing any obstacle the
environment could put in their path,

(B)appear to have been equipped to face any
obstacle the environment could put in their path,

(C)appear as equipped to face any obstacle the
environment could put in their paths,

(D)appeared as equipped to face any obstacle the
environment could put in their paths,

(E)appeared to have been equipped for facing any
obstacle the environment could put in their path,

选B。 还是不是很理解appear to have been equipped 这个时态的用法，还有 CD,两项paths 不是很理解，虽然OG解释过了。。

楼主好，我帮帮你~
C和D中的path应该是单数，因为一种动物进化应该只有一种进程的进化方向，不可能很多种~所以这里自然是path~

而这里的appear to have been equipped 你就记一下吧，我也是问的别人，这个是“似乎做过某事”，固定搭配~这个have done的动作发生在appear之前~（ps:这些都是cd上的nn们给我讲的~我也是刚明白）

谢谢啦！！翻其他帖子的时候意外看到了以前发的帖子的回复。。太惊喜了~~

查帖子发现以前我的回答不对，太肤浅，今天查到一个自己很满意的答案~算是补充一下以前的自己吧~

from baby姐：

这题因为有appear，正常情况下是"appear to do"对不对？或者说"appear to be"，但为了简洁，把"to be"省略。
He appears an idiot.
He appears to have Neurodegenerative Diseases.
这是现在时的appear的情况。那么咱要说从现在看，过去的东东咋样，就应该从时态上“退位”一步。因为appear后面只能跟不定式to do/be，你不能说
"appear to did/was/were"，那怎么办呢？就只好说"appear to have been" "appear to have done"，就这个道理啦。
Dinosaurs appear to have been relatively smart.

appear to have been done 不定式的被动完成时态啊
