1.首先need
to
do
是需要做........,need
为实义动词。
don't
need
to
就是上面的否定形式。不需要做......这里面need
还是实义动词
2.needn't为情态动词。后面接实义动词原型。即needn't
do
....意思是“不需要做....”
3.need
to
be
done
:
某物需要被做。。。
例:The
car
need
to
be
repaired.
汽车需要(被)修理(汽车和动作修理之间是被动关系不是主动关系)
4.need
doing主动表被动的用法
=need
to
be
done.
即
The
car
need
repairing.=The
car
need
to
be
repaired.
