Question

【题目】He has finished his homework ________ this week.

A. in the end B. at the end of

C. end up with D. by the end of

Answer 1

【答案】D

【解析】

句意：他在本周末完成了家庭作业。A. in the end终于，最后；B. at the end of在…结尾，在…末端；C. end up with以…结束；D. by the end of到…为止。结合语境分析A/C不正确；at the end of this week，主句要用一般将来时，所以B不对；by the end of常与完成时态连用。因为本题的主句是现在完成时，因此用by the end of。故选D。
