Unit2 Home Sweet Home 核心语法专项练习题情态动词表请求许可

 

## 本单元重点语法：Can / Could 表请求、许可

### 核心学习要点

1. **Can**：现在/日常请求、许可，语气普通；

   句型：Can you do sth?（你能……吗？）/ Can I do sth?（我可以……吗？）

2. **Could**：更委婉礼貌的请求，不分过去时态，日常礼貌首选；

   Could you…? / Could I…? 回答统一用 can / can’t，不用 could

3. 答语区分：

   肯定：Sure / Of course / Yes, you can.

   否定：Sorry, you can’t. / No problem, I can’t.

4. 易混区分：could 表过去能力≠礼貌请求；本单元只考礼貌句式

5. 高频易错：问句用could，答句不能用could；人称对应；情态动词后必用动词原形
