现在进行时的功能
与英语中的所有时态一样，说话者的态度与行动或事件的时间一样重要。当有人使用现在进行时时，他们想表达的不一定是“某人正在干某事”，而是“某人正在干，但还没干完某事”。
现在进行时有如下几种用法：
- 描述此时正在进行的动作：
You are using the Internet.
You are studying English grammar. - 描述在当前阶段内的活动或正在进行的操作、正在发生的事：
Are you still working for the same company?
More and more people are becoming vegetarian. - 描述已经计划或准备要在将来做的事情:
We’re going on holiday tomorrow.
I’m meeting my boyfriend tonight.
Are they visiting you next winter? - 描述临时事件或情况：
He usually plays football, but he’s playing basketball today.
The weather forecast was good, but it’s raining at the moment. - 和”always, forever, constantly”这几个词一起用, 描述和强调一系列重复的行动：
Harry and Sally are always arguing!
You’re always complaining about your homework! - 带有鲜明的时间状语，如Now，或带有look, listen等暗示动作正在进行，或有表示现在正在进行的上下文语境：
Listen！ Our teacher is sing a English song!
-Where is your father? -Oh, He is cleaning his car.
