Could you (please) do... 句型的否定形式是：
Could you (please) not do... 你可以不...吗
表示请求帮助或请求允许的疑问句中，常用could代替can，表示礼貌、委婉或不确定，而can则不具备这些语气。这时不能把could看作can的过去式。以上两句型中用could是为了表示礼貌的请求
—Could I use your computer
—Sorry, I’m going to work on it now.
—Well, could I watch TV
—Yes, you can.
Could I/you please …？表示一种有礼貌的请求或提议，其后连接原形动词，比Can you /I…？语气更委婉。类似句型有：
Would you like + sth. / to do sth.
May I + do sth.
Would you mind + sth. /doing sth.
What / How about + sth. /doing sth.
肯定回答有Sure. /Of course. / Certainly. /OK. /Great. / Well. / Good idea. / I agree. 等。否定回答有Sorry… / No, you can’t. 等。
