请看：

In the 1980’s the rate of increase of the minority population of the United States was nearly twice as fast as the 1970’s.

(A)   twice as fast as

(B)   twice as fast as it was in

(C)   twice what it was in

(D)  two times faster than that of

(E)   two times greater than

答案是C。为什么B不对？？请牛人指导。。。

而在另一个例子中：

According to a recent poll, owning and living in a freestanding house on its own land is still a goal of a majority of young adults, like that of earlier generations.

(A)   like that of earlier generations

(B)   as that for earlier generations

(C)   just as earlier generations did

(D)  as have earlier generations

(E)   as it was of earlier generations

答案是E。it指代owning and living in a freestanding house on its own land.，was 后面省略了a goal。

为什么在第一个例子中，it 就不可以指代the rate of increase of the minority population of the United States？？

twice 与as fast as语义冲突(rate不能as fast as)；请注明题目出处。what it was其实是倒装what was it，it指代the rate...。what指这个数字。

60. According to a recent poll, owning and living in a freestanding house on its own land is still a goal of a majority of young adults, like that of earlier generations.

(A)  like that of earlier generations

(B)   as that for earlier generations

(C)  just as earlier generations did

(D)  as have earlier generations

(E)   as it was of earlier generations

The intended comparison should be completed by a clause beginning with as and containing a subject and verb that correspond to the subject and verb of the main clause. In E, the best choice, it refers unambiguously to the phrasal subject owning ... land, the verb was corresponds to is, and today's young adults are appropriately compared to earlier genera­tions. Choices A and B lack a verb corresponding to is and a clear referent for that. Choices C and D are confusing and illogical because their verbs, did and have, cannot substitute for is in the main clause.
