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
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：
