Which one is correct?

He is ______ off retirement plans.
A. waiting
B. puts
C. put
D. stopped
E. putting

选E

a 没"wait off"这种用法
b 空前有“is”后不可能跟puts 单三形式
c “be put” 为被动式，不符题意
d “stop off”：中途稍作停留做某事
eg：stop off at the pub on the way home
e 正解~ “put off”:推迟，延缓，或拖延某事物

put off 其他意思：

1.驶离码头
we put off from the quay
2.停住让某人下去
put me off near the town center
3.推迟或取消与某人的会议或约会
she put him off with no excuse
4.使某人不高兴，惹人反感
the business man's offhand manner tend to put people off
5.打扰某人 put sb off sth
the sudden noise put her off her game
6。关掉某物
could you put the lights off before you leave?

答案是E。 首先根据is应该判断是使用现在进行时，表示正在发生或持续的情况。 其次从句意来看，应该是他在延迟退休的打算，固用put off：推迟，推后。
