英语语法,可能比较简单..有谁知道problems和questions的区别

Problem:现在有待解决的问题
Question:需要回答的问题
注意problem与question的区别：
problem 名词,问题,指有待解决的困难
例：What”s your problem?
固定用法：no problem 没问题,没关系
例：------“I have no money with me.”------“That”s no problem.I have.”
question兼作名词和动词,指“需要回答的问题；有待解决的疑难”和“提出疑问”.
例：Please answer my question.
It is a question of finding enough workers
