感官司动词都有哪些用法

感官动词的用法
1.see,hear,listen to,watch,notice等词,后接宾语,再接省略to的动词不定式或ing形式.前者表全过程,后者表正在进行.句中有频率词时,以上的词也常跟动词原形.
注释:省略to的动词不定式--to do是动词不定式,省略了to,剩下do,其形式和动词原形是一样的,但说法不同.
see sb do sth 看到某人做了某事
see sb doing sth 看到某人在做某事
hear sb do sth 听到某人做了某事
hear sb doing sth 听到某人在做某事
以此类推...
I heardsomeone knocking at the door when I fell asleep.(我入睡时有人正敲门,强调当时正在敲门)
I heard someone knock at the door three times.(听到有人敲门的全过程)
I often watch my classmates play volleyball after school.(此处有频率词often)
（了解）若以上词用于被动语态,须将省略的to还原：
see sb do sth----sb be seen to do sth
hear sb do sth----sb be seen to do sth
以此类推...
We saw himgo into the restaurant.→ He was seen to go into the restaurant.
I hear the boy cry every day.→ The boy is heard to cry every day.
2.感官动词look,sound,smell,taste,feel可当系动词,后接形容词.
He looks angry.
His explanation sounds reasonable.
The cakes smell nice.
The dishes taste delicious.

注意：如果加介词like构成词组,则后不可接形容词,而接名词或代词：
sound like 听起来像...
look like 看起来像...
He looks like his mother.
That sounds like a good idea.
It sounds like great fun.
It smells like a flower.
It tastes like salt.
3.如何判断look是实义动词还是感官动词?
当look理解为"看起来"时,是感官动词,后接形容词.
The naughty boys broke the window.The teacher looked angry.
当look理解为"看"或者与其它词构成词组时,是实义动词,需要用副词修饰.
The teacher looked anrily at the naughty boys.
