选择题
_______not to be late for the meeting, we arrived forty minutes _______ the required time, but after _____seemed hours of waiting, we were informed the meeting had been canceled.
A．So as; ahead of; what
B．In order; ahead of; what
C．So as; in advance of; it
D．In order; ahead of; it
答案
答案：B
考查短语及名词性从句。so as to与in order to 都是为了做某事，前者只能放在句中，后者句首、句中都可以；ahead of time提前，第三个空考查名词性从句，从句中缺少主语故用what，所以答案选B。
