初中英语题
you__get up early
1.needn't 2.need not to
为什么正确答案是1,2那里错了（要理由）

首先要弄清楚need 这个单词有两种用法,
用法一：need 做情态动词用.
做情态动词时,need +动词原型,
否定直接在need后加not.也就是needn't +动词原型
用法二:need 做一般的行为动词
做行为动词时,need to do sth.
否定形式要特别注意,不能在need 后直接加not,因为它是行为动词,一般的行为动词我们要加主动词来表示否定.所以它的否定形式是 do/di/does +not + need to do sth.
再来看我们的题,选项1,need 后加了not 再加上get 是动词原型,很显然是用法一.
选项2,need后加了not,但是后面却跟上了to do sth.这种用法既不用法一也不是用法二,所以不正确

急英语达人们you__get there by bus(needn't don't need to)括号里选哪个啊英语need用法I needn't to go out这里的need是情态动词怎么接不定式了类似的还有Need not have to,must,do not need,needn't的区别 don't need to 和needn't Xiao Li -----stay up late in the evening.need to , needn't 选 can/can`t/must/mustn`t/need/needn`t/have to/到底有什么区别?如题谢谢了为什么用you needn't wake him up,而不用you needn't to wake him up. needn't是等于don't need to还是don't need.为什么?“你不必为他的学习担心”是you nee You need something to drink,don't you?A,Not at all.B,I needn needn't和do not need to do有何分别? needn't to come,don't need come,don't need coming与needn't co needn't 和 don't need to 有什么不同?
