新东方补充资料，语法#82

82. Wind resistance created by opening windows while driving results in a fuel penalty as great or greater than is incurred by using air conditioning.

(A) as great or greater than is incurred by using air conditioning
(B) that is as great or greater than is incurred using air conditioning
(C) as great as or greater than that of using air conditioning
(D) at least as great as air conditioning's
(E) at least as great as that incurred by using air conditioning

表示A和B一样大或至少比B大
as great as…/greater than
at least as … as /at most as…as
as great as …, if not more so
's省略结构出现句子中必须有一个完整的's结构提示省略结构的意思
正确答案E 更对称

我选了B，新东方的石林说之所以选E，是因为 that incurred by 和前文的resistance created by对称。可我觉得这个说法不正确，在比较的明明是不同情况下fuel penalty的多少而不是resistance的大小。请问哪位NN能为我解释一下B为什么错，E为什么对吗？非常感谢！

E.

Wind resistance created by A ... at least as great as that (=wind resistance) (created) by B.

B. is wrong:

  as great AS / greater than.  the 2nd "AS" is missing in choice B. "as great ...than" is Wrong.

 Hope that helps.
