大全40

According to a study by the Carnegie Foundation for the Advancement of Teaching, companies in the United States are providing job training and general education for nearly eight million people, about equivalent to the enrollment of the nation's four-year colleges and universities.

(A)equivalent to the enrollment of

(B)the equivalent of those enrolled in

(C) equal to those who are enrolled in

(D) as many as the enrollment of

(E)as many as are enrolled in

E为什么是are enrolled ,我觉得are应该去掉才对啊！哪位高手帮我解释一下！！！

这是平行对称的规则阿，不可以省略的

这里是people和people 比较。原句是:as many as (people )are enrolled ....省略了People

as......(many) as后面可以接一个句子的，所以are不必去掉。比如：I reply the questions here as often as I can.
E选项使用了省略。如楼上所示。来造个句子：I buy a lot of oranges, about as many as (oranges) are sold in the shop.

OG 11th Verbial Review 的解释说, equal is generally used for uncountable quantities, such as equal justice, not countable quantities, such as people.

我不理解的是B错在哪里....OG说, the equivalent is too broad and vague a term for comparing groups of people. 但是这个理由我感觉也很vague啊....哪位NN给讲解一下的说....谢过....
