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

  2. Could I please use the car?

  Sure. / Certainly. / Of course. / No, you can't. I have to go out.

  在表示請求幫助或請求允許的疑問句中,常用 could 代替 can,以表示禮貌,委婉或不確定的語氣,而 can 則不具備這些語氣。這種情況下不能把 could 看作 can 的過去式。以上兩句中用 could 是為了表示禮貌的請求。表示請求幫助或請求允許時,除了 can, could 之外,還可以用 may,句子的表達方式也各有不同,可以用不同的方式來表示同一個概念。例:

  Could / Can / May I use your car for a day?

  作允答可以各種各樣:

  如同意可以說 Yes,或 Sure 或 Certainly,還可說 Yes, (do) please. 或 Of course. (you may / can). 或 That's OK / all right.

  如果不同意,可以說 I'm sorry you can't. 或 I'm really sorry, but I have to use it today. 要避免說 No, you can't. 這樣顯得很不禮貌。否定回答通常用委婉語氣。
