I have the difficulty _____ his father.(BnBBA)
A.teaching B.to teach
C.teach D.being teaching
请给出详细说明 谢谢

选a
固定句型
have difficulty in doing sth
做什么事情有困难
其中in可省略

A. teaching.

have difficulty in doing sth. 是固定的结构. B不对,不用不定式. C 更荒谬,D不用谈了,至少也要来个being taught吧???

选(A)

B
to teach 做后置定语修饰difficulty

也可以说:I have the difficulty IN teaching his father. 这里in teaching就可以理解为“在教……(这方面)”。

选A。
have difficulty (in)doing sth.是固定结构

答案是A have difficulty ( in) doing sth是固定搭配意思是做某事有困难. IN可以省去。
