need要有三大类五大用法。
一、作名词:
1.(be) in need / demand of 急需要某东西
2. meet the need / demand / requirement
3 There is no need for sb to do sth.
二、作行为动词(f否定是:don't /doesn't / didn't do )
1. sb need sth 跟名词,及物动词用法
2. sb need(s/ed) to do sth 跟不定式,不及物动词用法
3. sth/ sb need doing=sth/ sb need to be done 主动形式表示被动用法
三、作情态动词用(只用于否定和疑问句)
1. sb / sth needn't do sth
2. Need sb/sth do sth?
