英语概念题，求详解

如何区分什么时候用see sb doing 什么时候用 see sb do

Answer 1

解析过程：
感官动词 see, watch, observe, notice, look at, hear, listen to, smell,
taste, feel + do 表示动作的完整性，真实性；+doing 表示动作的连续性，进行性 。如：
I saw him work in the garden yesterday.
昨天我看见他在花园里干活了。(强调"我看见了"这个事实。)
I saw him working in the garden yesterday.（强调"我见他正干活"这个动作。）
昨天我见他正在花园里干活。
典型例题 ：
1）They knew her very well. They had seen her ___ up from childhood.
A. grow B. grew C. was growing D. to grow
答案：A。因题意为，他们看着她长大，因此强调的是成长的过程，而非正在长的动作，因此用see sb do sth 的句型。
2）The missing boy was last seen ___ near the river.
A. playing B. to be playing C. play D. to play
答案A. 本题强调其动作，正在河边玩，应此用see sb. doing sth句型。
规律方法：
hear sb / sth doing与hear sb / sth do.
hear sb / sth doing 表示听某物（某人）正在做某事，强调动作正在进行。
hear sb / sth do表示听到某物（某人）做某事，强调动作已完成。
如：I hear Lucy singing in her room.
我听见露西正在房间里唱歌。
I usually hear Lucy sing in her room.
我经常听到露西在房间里唱歌。
类似的动词还有 see , notice , look at , listen to等。例：
Do you hear someone knocking at the door? ( 讲时还在敲 )
I heard someone knock at the door three times . ( 讲时敲的动作已结束 )
I often see him dance in the classroom.
我经常看见他在教室里跳舞。
I see him dancing in the classroom.
我看见他正在教室里跳舞。如果还有其他疑问，可以去“状元365”提问。

表示平时常常（或偶尔，有时等）看到某人做某事，用see sb do.
I often see him play basketball with friends after school.

Answer 3

1. see sb doing sth 表示“看见某人正在做某事”，例如：I saw her lying there. 我看见她躺在那儿。（现在分词有进行时的意义。）
2. see sb do sth （注：不定式不必带 to）表示“看见某人/某物做完某事”，例如：I saw her face go pale. 我看见她的脸变得苍白了。
