– I have difficulty in learning English. I don’t know _______.
– Why not join an English club?
A. why to do                    B. what to do                   C. when to do

Answer 1

B

试题分析：have difficulty in doing sth.做某事有困难，why not do sth.为什么不……？why为什么，what什么，when什么时候，根据答语：你为什么不去参加英语俱乐部？可知上句意为：我学习英语有困难，我不知道该做什么？故选B。
