According to a 1996 survey by the National Association of College an University Business Officers, more than three times as many independent institutions of higher education charge tuition and fees of under $8,000 a year than those that charge over $16,000.

A) than those that charge

B) than are charging

C) than to charge

D) as charge

E) as those charging

The answer is E, but my choice is D. 此题考点是平行结构, as...as...应该连接的是两个句子，如果选E的话，则是句子和名词短语，不对称。请大家帮忙分析到底那个答案对，谢谢。

是收8000以下的independent institutions of higher education 和收16000以上的independent institutions of higher education 之间的比较。

不是8000和16000的比较。

同意楼上的，要把指代的词补上，否则歧义

charging是什么用法?与前面不平行对称啊.NN再给自己分析一下

毫无疑问是d
用google搜出了bbc news上非常类似的用法：

“More than three times as many people are killed by lightning as by violence at schools.”

总结下来，题目和上面的例句的共同结构就是：

more than three times as many people do 1 as do 2
