白勇 Ch.10 # 2

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.

D. as many as the enrollment of

E. as many as are enrolled in

我选了D，答案是E

白勇说D选项是8 million people和enrollment比较，概念不对等，没有可比性，而且as many as 配合单数名词永远错。

此外，白勇说E选项是省略了people做are enrolled in的主语，people与people比较。

为什么我觉得E看上去这么奇怪呢，如果把省略的people加回去，应该是as many as people are enrolled 吗？如果是这样的话，as 前后的比较对象在形式上不对等啊，simplified的结构是companies provide training to 8 million people as many as people are enrolled in colleges。

请问有谁能帮帮我吗？谢谢拉

as many as (those people who) are enrolled in

前后分别是：8 million people和those people

对等啊

,(nearly 8 million people is) (=who is) about as many as ( people) are enrolled in

as..as前后是两个形式平行的句子且比较对象要对等；第一个as前的从句谓语is被省略了，后面的as后的从句谓语are就不省略了.

如果是这样的话，who在定语从句中做主语不可以省略吧？

应该做宾语才能省略的啊

请指教！
