问题描述：
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
have difficulty (in) doing sth 固定短语，做某事有困难
答
注意，没有have difficulty to do sth这个短语！
做某事困难时have difficulty （in） doing sth！
此时difficulty不可以用复数。
LZ，注意你的difficulty多了一个f~
答
不是
是have diffficulty in doing sth
或者把in省略
即have diffficulty doing sth
答
A difficulty不能用复数，固定用法 所以选A
答
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
