一、提出礼貌的请求
culd表示委婉地请求，其句型结构主要有：
1. Culd yu +动词原形+
2. Culd yu please+动词原形+
意为＂请你做……好吗? ＂句型2比句型1语气更加委婉。肯定回答：Yes, sure. / Sure. / Of curse. / N prblem. 否定回答：Srry. / Srry, I can’t.
☞ Li Lei, culd yu please help me? 李雷，请你帮我个忙好吗？
☞ —Culd yu cme here sn? 你尽快过来，行吗？
—Sure. 当然可以。
☞ —Culd yu please clse the windw? 请你关上窗户好吗？
—I’m afraid nt. 恐怕不行。
【注意】其否定结构为：Culd yu（please）nt
【知识拓展】
二、表示请求许可
1. culd表示请求允许，其句型结构为：
Culd I/we +动词原形+ 意为＂请问我（们）能做……吗? ＂
肯定回答：Sure. / Of curse. / N prblem.
否定回答：I’m srry / Srry, yu can’t. 若关系比较亲近，也可以直接说N, yu can’t.
【温馨提示】在以上句子结构中情态动词culd不是can的过去式，而是用来表示委婉语气的，后跟动词原形。
☞ Culd I cme in? 我可以进来吗？
2. 另外，用Culd I ...？时，表示请求对方准许，对方回答时不能用culd，而要用can。

—Yes, yu can. 是的，可以。
3. 对于这种请求的肯定和否定回答的常用语
肯定回答常用语：Certainly. / Of curse. / With pleasure. / N prblem. / Sure. / Yes, yu can.
否定回答常用语：I’m afraid nt. / N, I’m afraid I can’t. / N, yu can’t.
三、culd与can的区别
culd与can都是情态动词，culd是can的过去式。二者都可用于表示请求，但是用法稍有不同：
1. can表示一般性的请求，语气随便，常用于熟人之间或长辈对晚辈、上级对下级的场合。
☞ Can yu tell us yur stry, Tny? 你能给我们讲讲你的故事吗，托尼？
2. culd表示有礼貌地请求，语气委婉，常用于非熟人之间或晚辈对长辈、下级对上级的场合。
