—Have you watered the plants yet, Kathy? —Yes. I that this morning.
A. will do
B. did
C. have done
D. was doing

A. will do (答案→)B. did C. have done D. was doing解析：句意：--- Kathy，你浇灌植物了吗？--- 是的。我今天早上浇的。由句意可知this morning是过去的时间状语，所以要用一般过去时，A. will do是一般将来时；C. have done是现在完成时；D. was doing过去进行时。故选B。考点: 考查动词时态的用法。
