ＮＮ指教！！as..as,or 比较级 than

ＬＺＭ的书上说对．看ＯＧ：

239.    Organized in 1966 by the Fish and Wildlife Service, the Breeding Bird Survey uses annual roadside counts along established routes for monitoring of population changes of as many as, or of more than 250 bird species, including 180 songbirds.

(A) for monitoring of population changes of as many as, or of

(B) to monitor population changes of as many, or

(C) to monitor changes in the populations of

(D) that monitors population changes of（C）

(E) that monitors changes in populations of as many as, or

Neither A nor B produces the idiomatic phrase “... as many as, or more than, 250...”—a phrase that would be needlessly wordy here. .

266.    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）

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

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.

我看ＯＧ似乎把as...as, or 比较级than归为wordy．　

我想问的是，象ＯＧ２３９那题，原句是as many as, or of more than这样，改成more than．．．不算改变原意吗？原句是，一样多，或者更多。改过后就只是：更多．

而２６６就没有什么争议了．很好的用了at least as ...as...　又简洁，又保持了原意！！！

盼指教！！！！

我觉得more than在239中并不是一个比较，它只是表达一个超过的意思，只有more than反而符合逻辑。

怎么理解呢？我看不出这个意思啊．

那别的情况呢？as great as,or greater than是对还是错？算不算wordy？改成greater than是不是改变原意了？

你把OG做完，或者大全，就明白其实有些题里as great as,or greater than是正确的。

你再体会一下，这里只能这样解释了。GMAT语法里逻辑也是很重要的。
