※ 引述《likeit (Epi)》之铭言：
: 22.[ Plants are more efficient at acquiring carbon than are fungi,]
: in the form of carbon dioxide, and converting it to energy-rich sugars.
: (A) Plants are more efficient at acquiring carbon than are fungi,
: (B) Plants are more efficient at acquiring carbon than fungi,
: (C) Plants are more efficient than fungi at acquiring carbon,
: (D) Plants, more efficient than fungi at acquiring carbon,
: (E) Plants acquire carbon more efficiently than fungi,
: 虽然知道选对了答案C
: 但是对选项A仍有疑惑
: 如果今天把are和fungi的位置对调 改成如下：
: Plants are more efficient at acquiring carbon than fungi are
: 是否就能变成正确答案呢?(也就是说A的写法本来就有误)
: 但以下句子两个都对:
: I know more about shakespeare than my brother does
: I know more about shakespeare than does my brother
: 如果A错的话
: 代表be动词不能像助动词一样调换位置?
: 还是A选项没有错...只是因为C选项比较好?
: 还请好心人解答了> < 谢谢!

很多考生都会疑惑比较后项补出助动词时，到底能不能倒装？
在此做进一步的讨论分析。
以下列出所有官方SC有用到比较后项助动词倒装的正确句子：
（特别见[ ]部分）
Because the Earth's crust is more solid there and thus better
able to transmit shock waves, an earthquake in the eastern United States
will typically devastate an area 100 times greater [than will a quake of
comparable magnitude occurring in the West.]
Inuits of the Bering Sea were isolated from contact with Europeans
longer [than were Aleuts or Inuits of the North Pacific and northern Alaska.]
Many teenagers undergo stress, but results of a recent study indicate that
the patterns of stress that girls experience are more likely to result in
depression [than are those that boys experience.]
The economy of Britain grew more slowly in the mid-1970's and declined much
more rapidly in the subsequent recession [than did the economy of the United
States.]
An exceptionally literate people, Icelanders publish more books per capita
[than do the people of any other nation.]
你可以发现一件事：比较后项的助动词其实是可以倒装的！
同时，经由这样的归纳下，我们可以发现，这些比较后项倒装之后的句子
[ ] 的地方都位于文中的结尾，后面不会再有任何修饰成分，避免产生修饰歧异。
这里也要提醒大家：
在研究一个自己所不了解的点时，请打开“正确句子集合”用全文搜寻，
就知道这个点有没有在GMAT的写法出现过，有出现过的句子又有什么特色，
来做纵向的归纳跟整理，文法大都有其背后的道理，
像以上的流程自己归纳、自己想通比较重要。
闲来有事没事正确句子也可以一天20句，多读两三遍，培养对GMAT流畅句子的语感。
