再问og266

og266.        In a recent poll, 86 percent of the public favored a Clean Air Act as strong or stronger than the present act.

(A) a Clean Air Act as strong or stronger than

(B) a Clean Air Act that is stronger, or at least so strong as,

(C) at least as strong a Clean Air Act as is

(D) a Clean Air Act as strong or stronger than is

(E) a Clean Air Act at least as strong as

答案：E

请问，E中为什么可以不像B有that is？B中的that is 应该省略吗？

E的结构实际上就是形容词性的短语（at least as strong as the present act）直接放在宾语后面修饰宾语吧，这种修饰方法是允许的吗？有没有其他的例子呢？

改变了句子重心

favor Act strong

不是 favor Act that is strong

我又看了一遍OG的解释：

E, the best choice, is concise, clear, and idiomatic. Choices A, B, C, and D may be faulted for constructions that are cumbersome, unnecessarily wordy, or unidiomatic. Choices A and D require as strong as instead of as strong. Similarly, B is missing than after stronger, and so should be as. In C and D, is should be dropped. Even with revisions, these choices are more wordy and awkward than the best answer.

OG中只说B更wordy and awkward，并没有提到改变原句句意的意思。

而且，白勇《语法全解》是这样说的：“此题第二步是看比较从句的省略。C,D选项语法上还原后的结构为a Clean Air Act that is at least as strong as the present act is。其中，定于从句要简化，应省略that is；as比较从句中的be动词is可省略。故排除C,D”

可见，此题中strong好像还是作为形容词修饰 a Clean Air Act，而不是作为副词修饰favor的吧......？？？

为什么that is 不能省呢？

that is是需要省略的，因为比较后没有补出助动词，所以已经说明是宾语间的比较，那就不需要that is了。

个人意见。
