According to a 1996 survey by the National Association of College and 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 OA is E, but I suspect the answer is D because OG37 uses the exact same construction (pasted below). I think for E to be correct, "charging" has to be changed to "charge" for the sake of parallelism in the "as...as" construction. D reads a bit awkward because the subject after the 2nd "as" is omitted but so is the correct answer in OG37. This is an important concept so I want to make sure that I get to the bottom of it. NN怎么看上面这道题?D的用法貌似和下面这道OG的一模一样为什么错呢?我下周就考了,要是有这么重要的概念还搞不清怎么行!!!
