这三个字加不加S要看你指单数还是复数。另外，有一两个习惯用法是只用单数的：如got in trouble with the police.
I've had troubles ever since I took this job.
A cause or source of distress, disturbance, or difficulty: The new recruits were a trouble to him.
这种情况不不用复数。
看你前面修饰problem的是单还是双，have problem to do sth or have some problems to do sth trouble和difficulty一样。
have a problem to do sth
have problems to do sth
