系动词之感官动词知识点讲解及练习
1.感官动词用法之一：see, hear, listen to, watch, notice等词，（后接宾语，再接动词原形或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。

）I heard someone knocking at the door when I fell asleep.(我入睡时有人正敲门)I heard someone knock at the door three times.(听的是全过程)
I often watch my classmates play volleyball after school. (此处有频率词often)
若以上词用于被动语态，后面原有动词原形改为带to不定式：
We saw him go into the restaurant.→He was seen to go into the restaurant.
I hear t he boy cry every day.→The boy is heard to cry every day.
2.感官动词用法之二：look, sound, smell, taste, feel可当系动词，后接形容词（此时，他们没有被动语态和进行时态。

）
He looks angry.
It sounds good.
The flowers smell beautiful.
The sweets taste sweet.
The silk feels soft.
I felt tired.
They all looked tired.
这些动词都不用于被动语态和进行时态。

如：
The sweets are tasted sweet.是错误的。

The sweets are tasting sweet.是错误的。

注意：如果加介词like,则后不可接形容词，而接名词或代词：
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.
