1. 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.

(A) so fast, and in some parts even faster than what they did

(B) so fast, and in some parts even faster than, those

(C) as fast, and in some parts even faster than, those

(D) as fast as, and in some parts even faster than, those（D）

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

可是D中those后面应该加did啊？

than从句后面如果是主语的话， 谓语动词/系词经常省略。

GMAT的大部分题目里更倾向于完整的表述，甚至经常倒装语序来强调某种语言效果， 是因为GMAT中的大部分都是正式的书面论调。
