need后动词是什么形式急.
初中一般只考:need to do sth.
还有need doing一般不考
The garden needs watering.
花园该浇水了.
I don't think you need to worry about this.
我认为你不必为这事担心.
need是情态动词时后跟动词原形

need to do sth
sth need doing
sth need to be done

原型

作情态动词时,后接动词原形,
作实义动词时,主语是人,后接动词不定式(to do ),主语是物时,接动词ing形式或to be done ,如
You needn't do it again.
It is cold, you need to wear warm clothes.
Your shoes need mending.

do或者是doing!

need当作行为动词要用need to do sth, We need to study hard
主语是物也可以need doing ,The bike needs repairing=The bike needs to be repaired
作为情态动词则跟动词原形 (need 作为情态动词只用于肯定句和否定句中)You needn't get up early
