OG蓝色 Verbal 87、103题疑问 关于比较结构中的平行

T87 原题：Last year, land values in most parts of  the pinelands rose almost so fast, and in some parts even faster than what they did outside the pinelands. 排除三个选项后剩下：

D) as fast as, and even in some parts faster than, those
E) as fast as, and even in some parts faster than what they did

正确选项是D, 但这里为什么D中省略了did 即rose这个动作？只是land values in...和those outside...够成了平行。难道是they指代不明的问题吗（这个理由lz觉得很牵强）

而在T103题中：Inuits of the Bearing Sea were in isolation from contract with Europeans longer than Aleuts or Inuits of the North Pacific and northern Alaska. 正确答案是：
D)isolated from contract with Europeans longer than were

此处比较的后者补上了be动词were构成一个倒装，而不是直接比较两个主语

lz的疑问是在比较结构考察平行时什么时候该省略助动词、be动词，如T87中，直接比较两个主语 什么时候又必需带上did, were等构成倒装呢？ 求路过的大侠不吝赐教！

同求教!!
我想问A were isolated from B longer than they were isolated from C.
和 A were isolated from B longer than C were isolated from than B.
这两个句子的省略形式是??

A were isolated from B longer than from C.
A were isolated from B longer than C were.

两种。

比较主语时，

当结构为主+谓(+状) 时，因为没有宾语，不会造成歧义，可以省略助动词；
当结构为主+谓+宾(+状)时，则为了避免主语和宾语比较的可能，不能省略助动词。

望指正。

为啥103题中的were要放到前面构成倒装啊,什么时候需要倒装?
