情态动词should
should为情态动词，意为“应该；应当”，不能单独作谓语，后面接动词原形，没有人称和数的变化。否定形式是在其后加not，可缩写为shouldn’t。谓语中含有情态动词should的肯定句变为一般疑问句时，把should提到主语之前。其基本用法如下：

You should go home and get some rest. 你应该回家休息一下。

1. 用于提出请求或要求
“Could you please … ”意为“请你……好吗？”，用于提出请求或要求。常用回答如下：

— Sure. / Of course. / Certainly, I could. 当然可以。
注意：同意他人请求的答语，一般只用can，而不用could。

He said he couldn’t follow me. 他说他跟不上我。
