---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(dá)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。
