虚拟语气高难度（语气MODE）

指出下列句子中陈述作为事实的某个事物的动词，用于提问问题的动词，谈及某个仅仅是想到的东西的动词，以及表达命令的动词：—

1. He knows his lesson today.

2. Are you first in the class?

3. I hope that he succeed.

4. Put away your books.

动词用来呈现想法的方式，称为动词的“语气”。

用来陈述作为事实的某个东西，提问问题或表达一种与事物的实际状态相联系的情况的动词，处于“直陈语气”（indicative mode）；如，He reads well. Does he read well? If he was guilty, his punishment was too light.

用来表达某个仅仅是想到的东西的动词，处于“虚拟语气”（subjunctive mode）；如，I wish that he go. If he were present I would speak to him. Your kingdom come.

注：—假设句（条件句）中的动词，只有当它表达某种仅仅是想到的东西时，才处于虚拟语气。

表达命令或要求的动词处于“祈使语气”（imperative mode）；如，Come into the house. Open your book.
