情态动词could的用法
情态动词could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,它本身不能做谓语,必须和不带to的动词原形一起构成谓语。
一、基本用法
1. could用于第一人称,表示希望得到对方的许可。
句型Could I...?意为“我可以做.…...吗?”,用于请求对方允许自已做某事,此时could 不是can的过去式。
肯定回答:Yes, you can./Yes, please./Yes, sure./Certainly.
否定回答:No, you can’t./Sorry, you can’t./No, I’m afraid you can’t.。
例句: —Could I smoke here, please?请问我能在这里抽烟吗?
一Yes, you can.是的,你能。
—Could I go to the movies with my friend tomorrow, Mum?
妈妈,我明天可以和朋友去看电影吗?
—No, you can’t. You should take your piano lesson. 不,不行。你要上钢琴课。
2.could用于第二人称,表示委婉地提出请求。
句型Could you(please)do...?意为“(请)你做..….好吗?”,用于提出要求或请求,其否定形式为Could you please not...?
肯定回答:Yes, sure/of course.(是的,当然可以)。
No problem.没问题。
With pleasure.乐意帮忙。
Sure/Of course/Certainly, I can.当然可以。
否定回答:Certainly not, 当然不。
Sorry, I can’t. I have to...对不起,我不能。我得...…
Sorry, I’m going to...对不起,我将要...…
I’m afraid I can’t. I have to...我恐怕不能。我得..….
I’m afraid not.恐怕不行。
例句: —Could you come here soon 你尽快过来,行吗?
—Sure. 当然可以。
—Could you please close the window 请你关上窗户好吗?
—I’m afraid not. 恐怕不行。
【注意】其否定结构为:Could you(please)not do...
二、特殊用法
1.表示请求允许,即请求别人允许自己做某事,could和can都可以用,但could语气更委婉。
例句:Could/Can I go?我可以去吗?
2.表示给予允许,即自己允许别人做某事,一般只用can,而不能用could.
例句:—Could I use your dictionary?我可以用你的词典吗?
—Yes, of course you can.当然可以。
三、could与can的区别
could与can都是情态动词,could是can的过去式。二者都可用于表示请求,
但是用法稍有不同:
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。
例句:Can you tell us your story, Tony 你能给我们讲讲你的故事吗,托尼?
could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。
例句:—Could you tell us if it snows in winter in Australia
请告诉我们,澳大利亚冬天下雪吗?
—Sure. 当然可以。
【知识拓展】
Would you mind doing sth 也可表示请求,常用句型: Would you please + do sth Would you + do sth 肯定回答:Sure. / Of course. / No problem. / I’d love to. 否定回答:Sorry. / Sorry, I can’t. / I’d love to, but... —Would you mind cleaning your room 你介意去打扫你的房间吗? —No. I’d like to. 不,我很乐意。
