need to do和need doing的区别

问题描述:

need to do和need doing的区别

没有区别.注意不能写成need to doing ,有to不能加ing

need to do 是需要做某事,need doing 就不知道了.

need doing是need to be done的简写形式,其实就是need to do 的被动语态

没有什么区别吧

当然有区别啦!
need doing是指sth.需要干什么.例如:My bag needs washing.
need to do 是指某人必须做某事.如:I need to do my homework.
need to do的否定有两种,don't need to do 和needn't do ,但后者只能用于否定.相当于haven't to do.

哪有need doing ?
need做实意动词,need to do sth
need做情态动词,need do sth
没见过doing形式

need to do 需要做某事need doing 是需要被做有被动的意思如;I need to wash my clothes.My clothes need washing.need doing = need to be doneI need to mend my bike.My bike needs mending.

need to do 中的need 是动词,它后边接动词不定式
need doing 中的need是系动词,它和be的用法是相同的 我们老师这么说的,应该是最简单的区分方法了吧~
