[讨论]LZM中的一道语法题

Violence in the stands at soccer matches has gotten so pronounced in several European countries that some stadiums have adopted new rules that aim to identify fans of visiting teams and that seat them in a separate area.

A. to identify fans of visiting teams and that seat them

B. to identify fans of visiting teams and seat them

C. to identify fans of visiting teams for seating

D. at identifying fans of visiting teams so as to seat them

E. at identifying fans of visiting teams and that seat them

为何答案是B，不是aim at doing sth吗？

平行角度B is best。也许seat前加to可能更好，不过这里也没有其它项可选。

A, E的错在于that aim 和 that seat意思上不平行，seat应该和identify平行。aim sb./sth.at doing和aim to do都对。

C, D分别用了for和so as to似乎想要表达identify的目的，但与aim to有重复的嫌疑，so as to 大多是错，除了前面主谓是系表结构(be)。aim直接加at，一般不用。
