英语need? sth啊1有什么区别啊？？？？？？

need既可做情态动词,又可做行为/实义动词,还可以做名词.
1. 做情态动词时,其后加上动词原形(像can/must一样),有need do sth,但它很少用于肯定句,多用于否定句和疑问句.
need (not) do sth (没)有必要做某事
如: Need he finish his work now?
He needn't finish his work now.
2. 做行为/实义动词时,一般有如下结构
1)need sth/sb 需要某人/某事
如: I don't need you. I need your help.
2)need to do sth 需要/有必要去做某事
如: You need to work harder.
3)need sb to do sth 需要某人去做某事
如: I need you to help me.
4)sth/sb need doing=sth/sb need to be done 某人/某事需要被...
如: My watch needs repairing.
=My watch needs to be repaired.
3. 至于做名词的用法因为和你的问题关系不大,不多说了.

你这是什么题目啊？我没看懂。你补充说明下。
