问题补充：

.Mary is so wet. She in the rain.

A. must be caught

B. must have been caught

C. should have been caught

D. can have been caught

答案：

A. must be caught

(答案→)B. must have been caught

C. should have been caught

D. can have been caught

解析：“Mary浑身都湿透了。她肯定淋了雨。”“淋雨”是过去的情况，因此是对过去情况的猜测，而should have been caught意思是“本应该淋雨”不符合题意，答案B。
