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.
than those that charge
than are charging
than to charge
as charge
as those charging
题目分析：
本题考查“比较”的知识点。首先，表示比较时，as…as…和more…than…均可以。例如，我们可以说：three times as many as，也可以说：three times more than（当然，这两者表示倍数不同）。但是，as必须和as搭配，more必须和than搭配，不能混搭。由于本题已经讲过了more than three times as many，所以划线部分必须以as开头。排除(A)(B)(C)。这道题目的意思是：收取学费少于8000每年的高等教育机构是超过三倍于收取超过16000每年的学费的机构的。由于as many as中间是一个行为，即，independent institutions of higher education charge tuition and fees，因此本题的对比对象应为两个收费行为，as身后应该用动词charge over $16,000，不能比较机构数(those charging over $16,000)。
选项分析：
略。
选的E， as many as正确，但是意思理解错误。3倍比较的是价格（16000 vs 8000），而不是机构数量，those一加上就成了比较的机构了！！！
as A as B，A是比较的东西，B是比较对象
e, 后半句话没谓语，相当于在比较机构数
完整的句子：
more than three times as many independent institutions of higher education charge tuition and fees of under $8,000 a year as independent institutions of higher education charge tuition and fees over $16,000.
相当于省略了主语，如果补齐应该是more than three times as many independent institutions of higher education charge tuition and fees of under $8,000 a year as those charge over $16,000. 之所以选D不考虑其他选项是因为D是唯一有动词可构成对象平行的答案...
as many independent institutions charge tuition and fees of under $8,000 a year as charge over $16,000，这里实际是将as charge tuition and fees of under $8,000和as charge over $16,000两件事情进行比较，不再比较两个组织。
more than three times as many 【independent institutions of higher education charge tuition and fees of under $8,000 a year 】as 【 ( independent institutions of higher education) charge over $16,000】
比较的是收费不是机构。
比较时，省略的结构应该在前面可以找到对应的结构。所以E选项的charging在前面并没有出现，
你说的不对
这是ron回复的中译版...你可以去曼哈顿论坛找找看
亲，不是找charging，是找institution哦

D中的charge over $16,000和前面的charge tuition and fees of under $8,000 a year 对称，charge前面省略了institutions of higher education
E中的those 可能有歧义，不知道是指代institutions of higher education 还是指代tuition and fees，如果要消除歧义，把E中的charging改为charge这样those就可以明确地指代institutions of higher education
D和E都对。
as many... as ...
第一部分是句子，核心词是charge 第二部分也应该用句子，省略与前相同的主语
E选项核心词是those名词，错
这道题是一个as引导的比较从句，涉及省略
more than three times as many independent institutions of higher education charge tuition and fees of under $8,000 a year as（ institutions of high education） charge over $16,000.
由于主语相同，所以把主语是省略了，谓语省略，仍然保持相同charge。而E的谓语变成了charging所以错误
由于as many as中间是一个行为，即，independent institutions of higher education charge tuition and fees，因此本题的对比对象应为两个收费行为，as身后应该用动词charge over $16,000，不能比较机构数(those charging over $16,000)。
More than 3 times as A charged tuition and fees of （under $8000） a year as... over $1600
比较的是宾语
choice E is definitely a loser in that contest: you have "charge"||"charging...", versus "charge"||"charge" in other choices. 完美平行
it is possible to construct a correct sentence with the structure appearing in choice E.
e.g.,
Schools charging less than $8000 per year provide the same liberal education as those charging over $16,000 per year.
哦哦哦哦哦 好对哦
More than 3x as many colleges charge certain fees as colleges THAT charge over $16000.转化一下 分析选D
MARK. 应该比较 charge 行为 而不是机构 因为原句 many independent institutions of higher education charge tuition
老师想请教您：为何中间不可以比较的是 不同的机构呢？总感觉那样子读起来很顺。。。

you do not have to know HOW TO WRITE comparison sentences.
...because this is a multiple-choice exam.
you need only be able to compare answer choices and make relative judgments. (this is a good thing, because writing comparison sentences is VERY hard--even for native speakers of english--and is nearly impossible for english learners to master fully. on the other hand, it's not nearly as hard to make relative judgments.)
