24-20 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
我這的標準答案是 E 但是我選的是D, 因為若as 當關代解, 代的是 institutions, 因該還蠻合理的...但是對於 E 用charging 怎麼看就不平衡吶 !
