请问为什么Be late foe school的否定是Don't be late for school
请问Don't be late for school的语法结构应该如何看啊
为何助动词后可以接be动词呢
be动词的否定不是应该用be not 吗

Don't be late for school这是个祈使句.其实是省略了主语you.
don't是组动词,后面就带动词原形,be动词也是属于动词的一种啊,所以可以用be.再加上late是形容词,所以应该由be动词来连接,late做be的表语.understand?
你加了补充 ,be动词的否定不是应该用be not 吗,那我就解决完这个吧.
Be 动词的否定是be not没错,但是这个是祈使句的否定句,直接用don't就行了,前面否定.
再给你举例说说祈使句的否定用法.
例如 never be late for school...don't watch TV.
Don't be worried about that...
明白了没有?假如不明白的话,再给我留言吧
