英语need doing和need to do有什么区别

前者有主动意思后者有被动意思

need doing 中的 doing 被视为一个 动名词相当于 sth
此时 need 相当于 want
need to do 表示 需要做·····
比如：
the flowers need watering（watering 是动名词）=
the lfowers need to be watered.

need doing=need to be done，主动表被动。类似用法还有want, require等。
例：The flowers need watering. = The flowers need to be watered.花要浇水了。
need to do 需要做某事
延伸：need do 需要做某事，这里need 是情态动词，没有人称变化，后边的动词前没有to。need to do也是需要做某事，但need 是行为动词，有人称变化，后面的动词要用不定式。
例：He need water the flowers. = He needs to water the flowers. 他要给花浇水了。

need doing 有需要被做的含义，need to do 一般是说主动去做

简单初级的讲：
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 done
I need to mend my bike.My bike needs mending.
具体的说：
need to do sth实义动词
need doing sth,表示被动
人＋need ＋to do
物＋need ＋doing
物＋need ＋to be done
请看下面的例子：
1．We need to collect the parcel before we leave for England．去英国之前,我们需要收拾好行李.
2．We need to tell him the truth．我们需要告诉他真相.
3．My car needs repairing．我的汽车需要修理.

need doing 表示正在做这件事
need to do 表示你需要去做这件事
