need的五种用法
need的五种用法如下：
1、need用作情态动词，后面接动词原形，通常用在否定句和疑问句中。
2、回答need时，肯定回答用must,否定回答用needn’t或don’t have to。
3、need用作实义动词时，有时态、人称和数的变化，后面加to do。
4、need to do和need doing。
need to do中不定式的逻辑主语就是主句的主语;need doing是主动形式表示被动含义，即need前的主语就是need后面的动词所表示的动作的承受者。
注意：want和require作“需要”讲时，和need的用法相同。
5、needn’t have done与didn’t need to do。
needn’t have done表示过去本不必做但实际上却做了某事。
didn’t need to do表示过去不必做而实际上也没做某事。
例句：
1、I need money and power now more than ever.
我现在比以往任何时候都更需要钱和权力。
2、You don't need to change yourself to meet the demands of the era.
你不需要改变自己来迎合时代的要求。
3、We have no special need for the site arrangement of the annual meeting.
我们对年会的现场布置没有什么特别需要。
