Yes, sure. / Sorry, I can't. I have to do my homework first.

Sure. / Certainly. / Of course. / No, you can't. I have to go out.
在表示请求帮助或请求允许的疑问句中，常用 could 代替 can，以表示礼貌，委婉或不确定的语气，而 can 则不具备这些语气。这种情况下不能把 could 看作 can 的过去式。以上两句中用 could 是为了表示礼貌的请求。表示请求帮助或请求允许时，除了 can, could 之外，还可以用 may，句子的表达方式也各有不同，可以用不同的方式来表示同一个概念。例：
Could / Can / May I use your car for a day?
作允答可以各种各样：
如同意可以说 Yes，或 Sure 或 Certainly，还可说 Yes, (do) please. 或 Of course. (you may / can). 或 That's OK / all right.
如果不同意，可以说 I'm sorry you can't. 或 I'm really sorry, but I have to use it today. 要避免说 No, you can't. 这样显得很不礼貌。否定回答通常用委婉语气。
