问题补充：

By the time he back last night, we had got 200 pictures of the Change-3 lunar probe.

A. came

B. had come

C. was coming

D. would come

答案：

(答案→)A. came

B. had come

C. was coming

D. would come

解析：句意：到他昨晚回来的时候为止，我们已经得到200张嫦娥三号月球探测器的照片了。By the time引导的是时间状语从句，时间是last night，所以用一般过去式，但是主句应该是过去完成时，选A。
