(2) No  problem. 没问题。用来表示同意和愉快的回答请求,也可回答感谢,意为“不客气”eg:---Thank you        ----No problem.
(3)Could 的用法:
could 用作情态动词,意为“能;可能”是can的过去式,(1) 用来表示过去的能力:She could swim when she was six. 她六岁的时候就会游泳。
a. 表示许可:can和could均可用,但用could 语气更委婉, eg: Can/Could I come
in? 我可以进来吗?
b. 表示推测:对现在或将来的推测,can和could均可用,但can 通常只用于否定句或疑问句中,一般不用于肯定句,而could则可用于肯定句、否定句和疑问句,eg: You could be right.
你可能是对的。
另外:could 还可用于虚拟语气中, 构成could have done 结构表示因过去可以做的事情没有做而感到遗憾惋惜,或者 couldn't have done 表示过去本不该做的事情而做了感到遗憾懊悔等等。eg: I could have stopped them fighting. 我本来可以阻止他们打架的。
