参考答案：

基本语法

情态动词could委婉地表请求和征询许可

其句型为：Could you please do sth？

—Peter， could you please take out the trash？

彼德，请你把垃圾倒掉好吗？

—Sure， Mom.

可以，妈妈。

—Could you please do the dishes？

请把盘子洗了，好吗？

—Sorry， I can’t.

抱歉，我不能。

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。could是为了表示礼貌的请求。

肯定回答时要用Yes， I can.

注意：不能用could。除此之外，肯定回答还可以用Sure. / Certainly. / Yes， sure. / Of course. / That’s OK. / No problem. / With pleasure.等；

否定回答用I’m sorry， I can’t. / I’m sorry， but I have to...， 还可以用I’m afraid not.

—Could you please sweep the floor？

—Yes， sure.

—Could you please water the flowers？

—No problem.
