Question

1--Did you finish your homework on time yesterday.

  --No, I didn't _______ on time. By the time I finished it, all my classmates

A. finish it; turned it in

B. finish it; had turned in it

C. make it; turned it in

D. make it; had turned it in

Answer

D

【解析】make it表示“做到”，故第一空四个选项都正确。而后一空根据时间by the time I finished it表示的是到过去某个时候为止，应用过去完成时；同时rum in是“动词+副词”型短语动词，宾语为人称代词宾格it，应放在rum和in之间。
