Unit 67 — see somebody do and see somebody doing
A. see somebody do
Study this example situation
Tom got into his car and drove off. You saw this.
You can say:
I saw Tom get into his car and drive off.
We say:
I saw him do something
= he did it and I saw this.
In the same way, you can say:
hear / listen to / watch / feel + somebody + do something
or:
hear / listen to / watch / feel + something + happen
Examples:
I didn’t hear you come in. (= you came in – I didn’t hear this)
Lisa suddenly felt somebody touch her on the shoulder.
B. see somebody doing
Study this example situation
Yesterday you saw Kate. She was waiting for a bus.
You can say:
I saw Kate waiting for a bus.
We say:
I saw her doing something
= she was doing it and I saw this.
In the same way, you can say:
hear / listen to / watch / feel / smell / find + somebody + doing something
or:
hear / listen to / watch / feel / smell / find + something + happening
Examples:
I could hear it raining. (= it was raining – I could hear it)
Listen to the birds singing!
Can you smell something burning?
We looked for Paul and finally we found him sitting under a tree eating an apple.
C. see somebody do 和 see somebody doing 的区别
1. I saw him do something
I saw him do something = he did something and I saw this.
表示：
我看到了这个动作的完整过程，从开始到结束。
例如：
He jumped over the wall and ran away. I saw this.
所以：
I saw him jump over the wall and run away.
再例如：
They went out. I heard this.
所以：
I heard them go out.
2. I saw him doing something
I saw him doing something = he was doing something and I saw this.
表示：
我看到的是动作正在进行中的一部分，不一定从头看到尾。
例如：
I saw Tom as I drove past in my car. He was walking along the street.
所以：
I saw Tom walking along the street.
再例如：
I heard them. They were talking.
所以：
I heard them talking.
3. 核心对比
| 结构 | 含义 | 重点 |

例如：
I saw him cross the road. = 我看到他过了马路。
强调：
完整的过马路动作
而：
I saw him crossing the road. = 我看到他正在过马路。
强调：
看到他时，这个动作正在发生
4. do = 完整动作
基本结构：
see / hear / watch / feel + somebody + 动词原形

I heard her sing.
We watched them play.
注意：
这里的动词原形前面不加 to。
错误：
❌ I saw him to leave.
正确：
I saw him leave.
5. doing = 动作正在进行
基本结构：
see / hear / watch / feel + somebody + -ing
例如：
I saw him running.

10. smell + something + doing
smell 常见结构：
smell + something + doing
例如：

强调正在发生的过程。
11. find + somebody + doing
find 也经常使用：

12. 有时候 do 和 doing 都可以
Sometimes the difference is not important and you can use either form:
I’ve never seen her dance.
or:
I’ve never seen her dancing.
两句话都可以表示：
我从来没看过她跳舞。
在这种情况下，是否强调：
完整动作
还是：
动作进行中
并不重要。

14. do 与一般过去时的关系
do 可以理解为：
完整发生的动作
例如：
He jumped over the wall.
↓
I saw him jump over the wall.
再例如：

I heard them go out.
因此可以建立这个思维：

15. doing 与过去进行时的关系
doing 可以理解为：
动作当时正在进行
例如：
Tom was walking along the street.
↓
I saw Tom walking along the street.

16. 最容易犯的错误
错误 1
❌ I saw him to leave.
正确：
I saw him leave.
错误 2
❌ I heard her to sing.
正确：
I heard her sing.
或者：
I heard her singing.
具体使用哪一个取决于你想表达：
完整动作
还是：
正在进行的动作
错误 3
❌ I saw him was running.
正确：
I saw him running.
如果使用完整从句，可以说：
I saw that he was running.
错误 4
❌ I heard them were talking.
正确：
I heard them talking.
或者使用从句：
I heard that they were talking.
17. 普通从句和 somebody doing 的区别
完整从句
I saw that Tom was walking along the street.
结构：
see + that + 主语 + 谓语
这里：
Tom = 主语 was walking = 谓语
somebody doing
I saw Tom walking along the street.
结构：
see + somebody + doing
这里：
Tom = somebody walking = doing
所以不能说：
❌ I saw Tom was walking.
应该说：
I saw Tom walking.
或者：
I saw that Tom was walking.

23. 最终时间轴
do：完整动作
START ───────────────────── FINISH
│ │
└────── 👁 全部看到 ─────────┘
I saw him cross the road.
doing：进行中的动作
START ───────── ACTION ───────── FINISH
↑
👁
看到其中一段
I saw him crossing the road.
24. 一句话记住 Unit 67
I saw him cross the road. = 我看到他过了马路。 = 强调完整动作。
I saw him crossing the road. = 我看到他正在过马路。 = 强调动作进行中。
最核心公式：
see / hear / watch / feel + somebody + do → 完整动作
