need有2种词性
1，情态动词 就是你说的need do
2, 实意动词 就是need to do

这两个都可以用，都是正确的，所以在肯定句中看不出区别
一般做题是从否定句中看出来的
1， needn't do
2, doesn't/don't need to do
这两种都是正确的

以下是一些干扰选项，都是错误的
needn't to do
doesn't/don't need do
因为它们混淆了情态动词与实意动词
needn't 是把need 看作情态动词，后面就不能再用to了
而dosen't/don't则把need看作实意动词，而后面加do， 又相互矛盾。

need既可以做实意动词,也可以做情态动词.
当need做实意动词时，用need
to
do
sth
如
you
need
to
drink
more
water
当need做情态动词时，用need
do
sth,就像must
do
sth一样的结构
如
you
need
wash
your
own
clothes
两种用法在意义上完全无区别，不过need做实意动词更常用，一般不将它作为情态动词来用
明白了吗？

1 need做情态动词
need+动词
（跟can一样的用法）
否定 needn't
1 need做实意动词
need to do
need sb to do
(与want类似）
否定为 do/does not need...
