姓名：____________

单元语法 情态动词could的用法

1. Could 表示有礼貌地提出请求。Could you (please) do...?表示“请你做...好吗？”或“麻烦你做...行吗？”could you (please) do...?的否定结构是在please 后加not。

Could you (please) set the table for supper?

Could you (please) open the window and close the door?

2. Could表示征求许可，希望得到允许。句型Could I do...?表示“我可以做...吗？”

Could I go to the movies?

3. 回答时应注意几个问题：

（1）对这样的句式作答时，与其它的一般疑问句不同，

作肯定回答通常用certainly, sure, of course等。作否定回答时，通常以sorry开头。

（2）回答could引导的问句时要用can或can’t，不能用could。

表示请求、征求许可的其他句型：Will/Would you please do…? 请问你能……吗？
