[求助]OG 251 （OG总结以外的）

题目如下：

251. The gyrfalcon, an Arctic bird of prey, has survived a close brush with extinction; its numbers are now five times greater than when the use of DDT was sharply restricted in the early 1970's. .

(A)  extinction; its numbers are now five times greater than

(B)  extinction; its numbers are now five times more than

(C)  extinction, their numbers now fivefold what they were

(D)  extinction, now with fivefold the numbers they had

(E)   extinction, now with numbers five times greater than

不太明白E错在哪？OG的解释是Choices D and E wrongly use a phrase introduced by now with to modify The gyrfalcon. In both choices, the phrase confusingly seems to parallel with extinction; a new clause with a present tense verb is needed to state what the gyrfalcon's numbers are now.

看选项E是觉得不太对，就是不知道到底错在哪里？？看了OG的解释还是没弄清楚

牛牛们都说作题光凭感觉是不行的，我牢记心上。所以还麻烦哪位牛牛给偶讲讲E这个到底错在哪？不胜感觉啊！！

E表面上与前面 with extinction平行了 错

因为从句意要求的是 说明gyrfalcon的数量 要另起一个独立的句子

恩恩。。。paopao大侠说的太棒了，

我明白了！！！非常感谢paopao大侠的说！！！！！

请问NN，这时一条规则吗？

Choices D and E wrongly use a phrase introduced by now with to modify The gyrfalcon. In both choices, the phrase confusingly seems to parallel with extinction; a new clause with a present tense verb is needed to state what the gyrfalcon's numbers are now.

这话解释的真ETS!

可以用這樣的方式判斷媽?

因為when 必須要有兩個從句組成

S+V+when S+V 所以用with 不行

不曉得這樣算不算一個判斷標準

請NN回答

E)extinction, now with numbers five times greater than

可不可以 treat "now with number five times greater than" as 独立主各结构? Is it correct as far as the grammar and logic are concerned, if for now the parallelism error with "with extinction" is ignored?

Still confused.

Please, could someone give a hand here?
