情态动词 can 和 culd 的用法
情态动词can和culd可用于向对方提出请求，也可用于请求对方允许自己做某事。它本身不能作谓语，必须和动词原形一起构成谓语。
情态动词 can & culd
1. 用于提出要求或请求 Can/Culd yu （重点）
2. 用于请求许可 Can/Culd （重点）
3. 用于表示能力 can表示现在的能力，culd表示过去的能力
情态动词culd的用法
情态动词culd构成的句型用于向对方委婉地提出请求或征求对方的许可。用于疑问句中，可代替can，在时间上与can没有区别，但语气要比can委婉、有礼貌。
1. 委婉地请求别人做某事（提出请求）(1)句型：Culd yu d…? / Culd yu please d…? 你能……吗? / 请问你能……吗?(2)肯定回答： Certainly./Of curse./With pleasure./N prblem./Yes, sure. 否定回答： N, I can’t./Certainly nt./N, I’m afraid I can’t.
1.用于提出要求或请求
Can/Culd yu please..? “请你···好吗？”/“你能/可以···吗？”，用于提出要求或请求。
e.g. —Can yu please lend me yur bike? 请把你的自行车借给我好吗？ —Sure/Of curse/Certainly. 当然可以。 —Culd yu please g hiking with me tmrrw? 请你明天和我一起去远足好吗? —Srry, I can't. I have t prepare fr a cmpetitin. 对不起，我不能。我得准备一个比赛。
练习：—Can yu g ut with us tnight? —I'd lve t, but I ______. I have t finish my wrk. A. can't B. mustn't C. needn't D. shuldn't
Can/Culd I...,? “我能···吗？”，用于请求对方允许自己做某事。常用的答语有：
Can/Culd I...,? “我能···吗？”，用于请求对方允许自己做某事。

练习：—Sam, ______ I jin yu in the cmmunity service? —Of curse yu can. A. culd B. must C. shuld D. need
特别提醒: 表示提出请求或请求许可（即请求别人允许自己做某事）时， culd和can都可以用，但culd语气更委婉。 e.g. Culd/Can I cme in? 我可以进来吗？ 但回应许可时，只能用can, 而不用culd(此时的culd只表示委婉语气，不表示过去式，故用can回答。当表示过去的能力时，才可用culd回答)。 e.g. —Culd I use yur pen? 我可以用你的钢笔吗？ —Of curse yu can. 当然可以。(此处不能用culd)
练习：—Simn, culd yu g t Huating Lake with me tmrrw? —Srry, I ________. I have t take care f my sick brther at hme. A. wn’t B. mustn’t C. can’t D. culdn’t
表示现在的能力用can, 表示过去的能力用culd。此时culd是can的过去式。 e.g. My sister can swim. 我妹妹会游泳。 He culdn't answer the questin at that time. 他当时不能回答那个问题。
