像have no trouble doing类似的have后面加to do 或 doing的短语都有那些啊，越多越好

have no difficulty(in) doing have no time (in) doing sth. have no chance(in) doing sth.…… have no +名词+doing都可以 have no time 加to do , have no reason to do have no doubt to do 两者区别,举个例子： have no time to do sth 没时间做某事 have no difficulty/trouble (in)doing sth作某事没有困难 in可以省略

have a hard time in doing

have fun doing
