常言道:良言一句三冬暖,恶语伤人六月寒。什么叫高情商呢?就是会说话、会办事。说起话来让人听起来舒服,做起事来让人感到温暖。你想做一名高情商、会说话办事的人吗?那么就跟我一起学习吧!看看情态动词could到底如何使用。
一、情态动词could的用法
1. can 的过去式;
2. 礼貌地请求;
3. 提出建议;
4. 表推测。
二、提出礼貌的请求
1. Could you +动词原形+...?
2. Could you 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 course. / No problem.
否定回答:Sorry. / Sorry, I can't.
—Could you please close the window? 请你关上窗户好吗?
—I'm afraid not. 恐怕不行。
其否定结构为:Could you (please) not do...?
三、表示请求许可
1. could表示请求允许,其句型结构为:
Could I / we +动词原形+...?意为“请问我(们)能做……吗?”
肯定回答:Sure. / Of course. / No problem.
否定回答:I'm sorry... / Sorry, you can't.
特别提示:在以上句子结构中情态动词could不是can的过去式,而是用来表示委婉语气的,后跟动词原形。
Could I come in? 我可以进来吗?
2. 另外,用Could I...时,表示请求对方准许,对方回答时不能用could,而要用can。
肯定回答:Certainly. / Of course. / With pleasure. / No problem. / Sure. / Yes, you can.
否定回答:I'm afraid not. / No, I'm afraid you can't. / No, you can't.
—Could I use your bicycle? 我可以用你的自行车吗?
—Yes, you can. 是的,可以。
四、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 you tell us your story, Tony? 你能给我们讲讲你的故事吗,托尼?
2. 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。
—Could you tell us if it snows in winter in Australia? 你能告诉我们澳大利亚冬天是否下雪吗?
—Sure. 当然可以。
