need的用法 老师讲过,需要做...用need to do sth,而need可以看作是情态动词也可以看作是动词,所以needn't后面必须是do sth.可是我看电视时发现有一句和老师讲的不一样,Need not to know(无需知道).那need究竟有怎样的用法呢?可以帮我分析一下needn't do sth和needn't to do sth这两者的区别吗?
1. 你老师讲得没错.
情态动词: need (not) do sth
行为动词: need sth/sb
need to do sth
need sb to do sth
sth need doing=sth need to be done
名词: there be no need for/of sth
there be no need (for sb) to do sth
in need (of...)
2. 否定形式应该是 needn't do sth
而need not to do sth也是有的(但不能缩写成needn't to do sth)
因为to do sth这个不定式本身也有否定式,不定式的否定全部是在to前加上not/never等否定词
3. 但是两者在翻译差别很大啊,要记住.
needn't do sth 没有必要做某事
need not to do sth 不做某事有必要
如: You needn't ask him.
You need not to smoke as a student.
情态动词: need (not) do sth
行为动词: need sth/sb
need to do sth
need sb to do sth
sth need doing=sth need to be done
名词: there be no need for/of sth
there be no need (for sb) to do sth
in need (of...)
2. 否定形式应该是 needn't do sth
而need not to do sth也是有的(但不能缩写成needn't to do sth)
因为to do sth这个不定式本身也有否定式,不定式的否定全部是在to前加上not/never等否定词
3. 但是两者在翻译差别很大啊,要记住.
needn't do sth 没有必要做某事
need not to do sth 不做某事有必要
如: You needn't ask him.
You need not to smoke as a student.
need的用法 老师讲过,需要做...用need to do sth,而need可以看作是情态动词也可以看作是动词,所以
need do sth ,有这种用法吗,此时need 不是情态动词吗,我觉得可以有这种用法
Need to do的need是情态动词还是行为动词
need是情态动词 need do结构 为什么还有need to do
情态动词NEED的用法
need用法什么时候是情态动词什么时候加to
need to do 、need do我知道前者是实意动词,后者是情态动词,可是在用法上有什么明显的区别呢,
need做情态动词
need是情态动词吗
need的具体用法我们老师和我们说don't need to do sth.,但我还是搞不清楚,求具体的need做情态动
英语动词结构用法求英语的单词用法比如:want to do sth想要做某事need to do sth需要做某事多发点
