do you have any____out the problem.
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
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
