篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了need do和need to do如何用？啥时候用need do相关的知识，希望对你有一定的参考价值。
参考技术A 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.
