求语法高人指点 比较结构！！！！
不知道大家 有没有和我一样的困扰。。就是分不清比较结构里 到底谁和谁、 什么和什么在比较~~  以至于很多时候 遇见 XXX more than those ofXXX  或者XXXmore than that ofXXX  的时候，分辨不清 内个代词 those\that 之类的到底是指代错误 还是应该留着的~~~  在做比较结构的题时，有没有什么方法？？

再次记下了GWD中很困扰的句子，请高人指点点怎么去看 到底谁和谁在比较~~~

1、According to a 1996 survey bu the National Asscioation of College and University Business Officers, more than three times as many indepentdent institutions of higher education charge tuition and fees of under $8000 a year than those that charge over $16000.

A  略
B  than are charging
C  than to charge
D  as charge
E  as those charging

2、When working with overseas clients, an understanding of cultural norms is at least as important as grasping the pivotal business issues for the global manager.
A 略
B   For global managers working with overseas clients, understanding cultural norms is at least as important as grasping the pivotal business issues

C   For global managers working with overseas clients, an understanding of cultural norms is at least as important to them as that grasp the pivotal business issues. (这个选项错在哪儿呀？？？)

个人觉得~
第二题，them 可以指代 managers，也可以指代 clients。个人觉得有点指代不清（相对性错误。）
再者。 C 中managers和clients都是负数，而与 an understanding 这个单数不搭。起码manager是个单数吧~~再看看正确答案，确实很漂亮。。。

不知对不对~仅供参考

第一题是as many as结构，排除ABC，比较的对象为institutions为复数名词，要用those因此E正确，charging是做后置定语修饰those的。第二题C前后不可比哦。
