助动词后一定要加动词吗?还有在【Why are you always late for school?】中why为什么不能用do代替呢?
又及：【Why are you always late for school?】中的are不是现在进行时吗?
望懂得的前辈做个解答.

因为late为形容词,用be动词修饰
be + 形容词,也可以be + 动词ing表进行时.助动词（do,did） + 动词原形
如：He is late for school.be + 形容词
He is going to school.be + 动词ing
What do you want to do?助动词do + 动词原型
Why,What,How,When,Which,Where,How often,How long等这些疑问词构成的疑问句为特殊疑问句,Do构成的疑问句为一般疑问句
如：What is your job?特殊疑问句
Do you like meat?一般疑问句
再问：还想麻烦您一下，在一个有助动词的句子中，助动词后一定要加动词吗？
再答：是的，如 He doesn't like English. doesn't 为否定助动词，like为动词原型 Do you speak Chinese？ Do 为助动词，speak为动词原型 Would you like some bread？ would 为情态助动词，like 为动词原型

助动词后一定要加动词吗?还有在【Why are you always late for school?】中why为什么不 you are always late for school,can you ______ why 是Tell me why you are late for school还是Tell me why are you la Jack is always late for school.谓语动词是is非谓语动词为什么不加s --why are you late? Can you tell me?Why are you late for school today?合并改为含有宾语从句 "why are you late for school ,Tom?"Miss wang asks.改成间接引语 He asked me,”Why are you late for school?”改为间接引语. Teacher:Why are you late for school every morning?怎么读? ''Why are you late for school again?'' the the teacher asked My father said me,"Why are you late for school"改为间接引语英语翻译1.[[why are you late]]teacher:why are you late for schoo
