标题: GWD3-Q28

GWD3-Q28:

The coyote is one of several recent ecological success stories: along with the white-tailed deer, the moose, and other species that are enlarging their natural domains, they have established themselves as supreme adapters in an era when the capability to adjust to the environmental changes wrought by human beings has created a whole new class of dominant large mammals.

A. they have established themselves as supreme adapters in an era when the capability

B. they have established themselves as being supreme adapters in an era when being able

C. it has established itself as a supreme adapter in an era when to be able

D. it has established itself as being a supreme adapter in an era when its ability

E. it has established itself as a supreme adapter in an era when the ability

正确答案是E. 但是这道题的结构没看懂。Along with..., the moose and other... 后面怎么会还有主语呢，不管是it还是they？就算有主语，and连接的两个主语，后面的代词也应该是用they啊？

标题: My idea
Hello,

This sentence has the structure that two clause are separated by a colon and the second clause explains further the first one. In the second clause, " along with ... their natural domains" is the propositional phrase modifying the subject "it", referring to "The coyote" in the first clause. "the white-tailed deer, the moose, and other species" is the object of the prositional phrase " along with" , even "They" , as subject in the second clause , cannot refer to "the white-tailed deer, the moose, and other species".

That's it.

"when ....." here needs a noun form as subject; and, "to be able to" is not a noun form.

哦。。。原来如此。我把“along with the white-tailed deer”看成单独的介词短语了。Thanks!

以下是引用dongsoong在2009/8/7 10:38:00的发言：
"when ....." here needs a noun form as subject; and, "to be able to" is not a noun form.

此解正确吗？是指when后要加完整句子的意思吗？

应是正解 to be able to 不能做主语··· 应为R选项的the ability

to be able to do sth 为什么不能做主语呢？

to be able to do sth 为什么不能做主语呢？

-- by 会员 zhanhualv (2010/9/15 16:09:45)

C的when to be able没有名词作主语，to do sth是可以做主语的，但是要to do sth is to do sth这个结构才可以。其他情况下to do 是不能做主语的。
懂了么？？？
