2 实义动词(意思为需要时) need to do
3 有些固定用法(表被动)sth needs xxx (need后直接加do)
如 my car needs wash 车需要被洗
my hair need cut
need作情态动词后加do
need作实义动词加to do
need兼有动词/名词两者词性。
1. need作为名词时，初中涉及较少，所以只提供几个常见结构以供参考：
1）in need of... 需要...
如：I'm in need/want of your help.
2）in need 有需要的/困窘的
如：A friend in need is a friend indeed.
3）There be no need of/for sth.
There be no need (for sb) to do sth ......是不需要的/不必...
如：There is no need of/for further discussion.
There is no need for you to help him.
2. need作为动词，有两种理解，一是做情态动词，二是做行为动词。
1）need作为情态动词时，一般不用于肯定句，只用于否定句/疑问句。
其后直接加动词原形，没有时态/人称的变化。
其否定句为在need后面直接加not，或使用缩写needn't.
如：I needn't work hard.
其疑问句必须把情态动词need提前，回答也一般借助于need.
如：Need I help you?
2）need作为行为动词时，可用于各种句子，有过去式needed和三单形式needs.
其否定句必须借助于助动词don't/doesn't/didn't等变化。
如：I don't need to work hard.
其疑问句也必须借助于助动词do/does/did等变化。
如：What do you need me to do?
其结构一般有：
need sb/sth 如：I need you. I need your help.
need to do sth 如：I need to work harder.
need sb to do sth 如：I need you to help me.
need doing = need to be done 如：My watch needs repairing. = My watch needs to be repaired
