I'm afraid that __________ the time we get to the museum, it will be closed.A.by B.with C.as D.till 首先,整理一下句子,I'm afraid that ---后面是宾语从句,单独分析---the museum will be closed ——在什么情况下关呢?__________ the time we get to the museum,这句子实际上是the museum will be closed 的状语。好了,关系清楚了。下面就是选一个恰当的时间问题了,A 在我们到之前。B 本身错,C,当我们赶到时D直到我们赶到。很显然,是在我们赶到前。选A。

by the time +句子 意思是到...时候。主句的时态取决于by the time 后面句子的时态,这里的by the time 起到连词的作用。By the time we got to the cinema , the film had been on for ten minutes.
