Question

__we had been looking forward to.

A then came the hour B before Rose the new C when the hour came D after Kate stands the new teacher
对选项都不理解。要怎么选

Answer 1

A then came the hour __we had been looking forward to.

然后，我们期待已久的时刻终于来到了。
we had been looking forward to后面要跟名词或短语。在这里把它提前了。
we had been looking forward to the hour, and then it came!
其他基本上都不能放上去的呢。
before Rose the new 在新……露丝来之前
when the hour came 如果把came放最后，可以考虑的，但不是句子，只是个从句，当我们期待已久的时刻到来……
after Kate stands the new teacher
站在Kate后面的是我们期待已久的新老师，用这句的话，最后应该再加上meeting.

Answer 2

C当那一刻到来时我们很期待；我们很期待那一刻的到来。

Answer 3

严格说来，
本题没有答案
。we
had
looking
forward
to按说应该是分割开的定语从句，修饰the
graduation
day
，因此
最佳
答案应该是
which
。如果题目就是这四个选项的话，
只能选c
，因为只有
what
可以在名词性从句中
作宾语
。
