关于need的用法
就是有 need to do ,need doing ,need sth,need sth for sth,need sth for help ,need do.sth need doing,sth need do这么几种用法,分别是在哪几种情况下使用

①need to do ,②need doing ,③need sth,④need sth for sth,⑤ need sth for help ,⑥ need do.⑦sth need doing,⑧sth need do当做实义动词的时候,need可直接加名词或to do所以就有need 主动语态就用①to do 表示被动含义时候就用②need+doing也就是所⑦表示某事需要被做③表示需要某东西④同③,不同的是for表示目的因为某事而需要某事这就有了⑤ 需要、、、来help（帮助）当做情态动词时,用法与must、can等一样都是在情态动词后直接加动词原形所以⑥ need do sth.⑧嘛、也是情态动词.sth need do 主动表被动
