need 和need to区别详细的更好哈
need 和need to区别
详细的更好哈

need 和need to区别详细的更好哈
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.

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...
