Grammar Focus 1. 用于请求别人做某事（提出请求） 句型与回答 常用句型 Can/ Could you ( please ) do sth.? 肯定答语 OK./Certainly./Of course./With pleasure./ No problem./Yes, sure.等 否定答语 Sorry, I can’t. I have to…/I’m afraid not./ I’m afraid I can’t. I am going to…等 Grammar Focus 2. 用于请求别人允许自己做某事（请求允许） 常用句型 Can/ Could I do sth.? 肯定答语 Yes, you can./Certainly./Yes, please.等 否定答语 Sorry, you can’t./I’m afraid you can’t.等 Grammar Focus 注意 回答时：在回答用 could 提出的请求时，通常不用 could而用 can。 例如： — Could I have a look at your book? — Yes, you can. (不能用Yes, you could.) — Sorry, you can’t. (不能用Sorry, you couldn’t.) Grammar Focus 注意 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? 肯定回答：Yes, you can. But don't stay up too late. 否定回答：No, you can't. You have to get up early tomorrow. Grammar Focus 情态动词 can / could 情态动词 can 和 could 都可用于表示能力、请求允许和给予许可，以及提出请求和建议。 1. 表示能力 例如：Can you speak English? 你会说英语吗？ When I was five, I could swim like a fish. 我五岁时游泳游得像条鱼一样好。（could是can的过去式） 补充内容 Grammar Focus 2. 提出建议 对平级或晚辈可用 can，快速给出建议； 对上级、长辈或需要体现礼貌时用 could，避免显得生硬。 We can eat in a restaurant this evening. 今晚我们可以在餐馆吃饭。 用 can 提出直接建议（常用于口语，语气较随意） Grammar Focus Maybe I could give you a lift to the supermarket. 也许我可以让你搭我的车去超市。 You could try reading the instructions before starting. 你可以试着在开始前先读一下说明书。 用 could 提出委婉建议（语气更礼貌、含蓄，适合正式或陌生场景） Grammar Focus 1.
