OG11-72 紫皮

centapple

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（A）

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

我想问一下E选项为什么不对，with numbers five times greater than可不可以看成独立主格成分呢？

两个with结构，中间用逗号，好像不靠谱~

如果E对,第二个with对应的语义是:has survived a close brush with fivefold the numbers...

基本上肯定得用分句，要么用转折词，否则即使按LS改了，逻辑上也不通的

我觉得， with numbers five times greater than= with+( numbers five times greater than),可以看作是一个介宾结构，后面直接+when，WHEN连接的应该是两个完整的句子（有主谓），而WHEN前是一个介宾结构，没有主谓，不对。
