"does,do"和"is"在一般疑问句的时候是怎么用的,是什么时候分别用什么?意思是什么

Answer 1

一般疑问句：
谓语动词为be的疑问句,只要将be (am,is,are)提到主语前即可.
I am fine.--->疑问句:Are you fine?
You are fine.--->疑问句:Are you fine?
He/She/It is fine.--->疑问句:Is he/she/it fine?
We/You/They are fine.--->疑问句:Are you/you/they fine?
谓语动词为实义动词的疑问句,一般在句首加助动词Do/Does(主语是第三人称单数加Does）,
谓语动词用原形：
例:I work.---> Do you work?（肯定回答：Yes,I do.否定回答：No,I don't.)
You work.（同上）
He/She/It works.--->Does she work?
(肯定回答：Yes,she doesn't.
否定回答：No,she doesn't.)
