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
正确答案是e，但是我选的是d。我觉得要those charging和than前面的不对称。。。 作者: sayysong 时间: 2009-12-14 14:15
