问题补充：
All the money Iby the time I arrived home.
A. ran out
B. had ran out
C. had had run out
D. was run out
答案：
A. ran out
B. had ran out
(答案→)C. had had run out
D. was run out
解析：考查定语从句和时态：句意：到我到家的时候为止，所有的钱都被用完了。这句话里面有个定语从句，I had，修饰the money，时间是by the time I arrived home.因为by和过去时间连用，时态应该是过去完成时，选C。
