肯定答语 OK./Certainly./Of course./With pleasure./
No problem./Yes, sure.等

情态动词 could 的用法
【注意事项】
回答时：在回答用 “could” 提出的请求时，通常不用 “could” 而用 “can”。
例如对于 “Could I have a look at your book ” 可以回答 “Yes, you can.” 而不是 “Yes, you could.” 语气态度：使用 “could” 只是让请求更礼貌，但仍要注意说话时的语气和态度，面带微笑、语调温和会让你的请求更易被接受。
例如：Could I stay up a little later to finish this movie
我可以晚点睡把这部电影看完吗？
肯定回答：Yes, you can. But don't stay up too late.可以，但别熬太晚。
否定回答：No, you can't. You have to get up early tomorrow.不行，你明天得早起。
