See sb. do和

　　See sb. doing

　　到底区别在哪里？

　　来听今天的讲解：

　　See sb. do

　　情景是Tom got into his car and drove away. You saw this.

　　可以说：I saw Tom get into his car and drive away.

　　如果是被动语态要+to

　　He was seen to get in the car.

　　See sb. doing

　　情景是Yesterday you saw Kate. She was waiting for a bus.

　　可以说I saw Kate waiting for a bus.

　　我们来区分一下两种结构在意思上的差别：

　　1.I saw him do something=he did something and I saw this.

　　我见到了动作的全过程，说话时，动作已经完成

　　He fell off the wall. I saw this. =I saw him fall off the wall.

　　The accident happened. Did you see it? =Did you see the accident happen?

　　2.I saw him doing something=he was doing sth. and I saw this

　　他正在做某事，事情正在进行中，还未完成，我只看到了过程中的一部分

　　He was walking along the street. I saw this when I drove past in my car.

　　=I saw him walking along the street.

　　有时可以互换：

　　I’ve never seen her dance. 或者I’ve never seen her dancing.

　　除了see外，还有一些动词也可以这么使用：

　　I didn’t hear you come in. 你已经进来了，我没听见

　　Lily suddenly felt somebody touch her on the shoulder.

　　Did you notice anyone go out?

　　I could hear it raining.正在下雨
