need to+ do的用法区别？

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.
