考点 01
情态动词 can 引导礼貌请求问句 Can you...please?
原文:
Mike: Excuse me, Baobao, can you help me, please?
迈克:打扰一下,宝宝,请问你能帮帮我吗?
Baobao: Sure, Mike. What can I do for you?
宝宝:当然可以,迈克。我能为你做些什么?
Mike: I can’t find my ping-pong bat. May I use your bat?
迈克:我找不到我的乒乓球拍了。我可以用一下你的球拍吗?
Baobao: Sure. Here you are.
宝宝:没问题,给你。
1. 基本含义
情态动词 can 本身含义 “能够”,在本单元用于向别人提出请求、寻求帮助。
Can you ..., please? 是日常基础礼貌请求句型,please 放在句末尾,加强礼貌语气。
2. 句式结构
✅ 问句:Can you + 动词原形 + 其他,please?
含义:请问你可以…… 吗?
✅ 肯定应答:Sure. / Sure, no problem. / Here you are.
✅ 否定应答:Sorry, I can’t.
3. 拓展区分
Can you...? 向对方提出请求(你能否做……)
May I...? 向对方征求许可(我能否做……)
两者后面都必须接动词原形。
例:May I use your bat? 我可以使用你的球拍吗?
4. 语法注意点
can 属于情态动词,没有人称和数的变化,后面永远搭配动词原形;变问句直接把 can 提前。
