need to do sth实义动词
need do sth. 没有这种用法，
有need doing，表被动
“need”作为实义动词时，通常用法是：
人＋need ＋to do
物＋need ＋doing
物＋need ＋to be done

need的基本意思是需要

表示必须的含义，用need to do sth.

表示应该的含义，用need to do sth.时可以省略to，同时，否定形式可以用need not do sth.
如果前面出现助动词，就不能省略to，如do not need to do

need doing前面的主语通常是指物的，在含义上是被动含义：
my clothes needs washing 这个句子是正确的。

need 可以是情态动词 也可以是行为动词

在表示情态动词的时候 need后面不能够加动词不定式
只能直接加动词原形 表示需要做什么事情

在表示行为动词的时候 need后面一定要加动词不定式
同样表示需要做什么事情

但是 在need表示被动的时候 比如
My clothes need washing.此时可以在need后面加动词的ing形态 也可以表示成My clothes need to be washed.
不过这个时候的need不是情态动词 而是行为动词

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.

my clothes needs washing 是不对，因为clothes是复式的，因此need后面不应该带个 s 了，我们第三人称单数形式才用 动词 + s 形式；
