do you have any____out the problem.

题目

do you have any____out the problem.
Do you have any____out the problem?( )
A.difficulty in working B.difficulty to work
C.difficulties working D.difficulties to work
但不是有两个短语么：have diffficulty to do sth和have diffficulty in doing sth.这样看来,好像A和B都可以啊?
难道没有have diffficulty to do sth这个短语么？

答案

先要记住have difficulty (in) doing sth 是固定短语,“做某事有困难”排B,D
另外 difficulty作为抽象名词时是不可数的,这句话相当于It is difficult to work out the problem.选A
