Unit 3 八年级英语下册语法知识归纳(人教版)(解析版)
Unit 3 Could you please clean your room?一．情态动词could的用法归纳①could表示过去的能力，是can的过去式。
e.g. I could swim when I was a child.He could speak English frequently when he was six .②could表示推测，既可以表示过去的可能性，又可以表示现在的可能性，比can的语气更弱。
可以用在肯定句，否定句，疑问句中。
e.g. He left 15 minutes ago,he could be at home now.Your father looks so young,he couldn’t be over fifty.③could表示有礼貌地请求及建议情态动词could用于有礼貌地提出请求,常用于疑问句,代替can,但是其语气要比can更加委婉、有礼貌。
其答语没有固定的形式,但必须符合语境。
1、表示礼貌的请求此用法句型结构:1. Could you+动词原形+其他?2. Could you please+动词原形+其他?意为"请你做……好吗?",句型2比句型1语气更加委婉。
肯定回答可用Sure/Certainly/Yes, sure/No problem/With pleasure等。
否定回答可用No，主语+can't/couldn’t.e.g.Could I use your phone?Yes,of course you can.二．can与could的辨析1.can和could均可表示请求许可，但could表示语气更加委婉。
2.当表示允许别人做某事时，用can而不用could。
3.表示推测时，can常用语否定句和疑问句中，could可用于肯定句中，比can的可能性小。
练一练一. 用can,could,can’t,couldn’t填空.1.He______ sing and dance. He is clever.【答案】can【解析】句意：他能唱歌跳舞，他很聪明。
