如题所述

Answer 1

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

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。

Answer 2

see sb doing sth 看见某人做某事（其中一部分过程）如：
When I passed her room,I saw her cleaning her room.(看到一部分）
see sb do sth 看见某人做某事（全部过程或全过程持续时间很短）如：
I saw him pick an apple.(pick an apple持续时间很短）
I saw him go into the room(强调全部过程）
see sb do sth 改成被动为：sb be seen to do sth.
see sb to do sth是不符合英语的表达的.本回答被提问者和网友采纳
