—Did you take part in the sports meeting last week?

—Of course I didn’t, don’t you know that it was because of the rain.

A. taken off

B. put off

C. kept off

D. set off

答案：

A. taken off

(答案→)B. put off

C. kept off

D. set off

解析：根据题干，本句的意思是“难道你不知道它因为雨被推迟了吗。”“推迟”是put off。而take off是“脱掉”“起飞”等，keep off是“让开”，set off是“出发，动身”，都不符合题意。所以本题选B。
