Answer 1

--Have you watered the plants yet?
--Yes. I___that this morning.
A. will B.did C. have done D. was doing
答: B
译：--你给植物浇水了吗？
--浇过了。早上浇的。
析：本题考时态。有陷阱。
因为问句是现在完成时，所以回答应该也是现在完成时，所以C项是最具有诱惑的选项。
事实上，出题者有意无意将标点打错了。Yes后应是句号！Yes.= Yes, I have. =Yes, I have done it. =Yes, I have watered them. 是最简回答。用句号表示这个问题我回答完毕。后来的是补充说一下做这事的时间的。有确定的过去时间，所以不能用现在完成时态。
