Question

have否定疑问是不是还是用have

所有的动词否定，疑问是不是都要回形了？比如He speaks English 的疑问是不是 Doeshe speak english

Answer 1

不一定
如果have表有的意思：
如:
I have got a dog.变为一般疑问句：Have you got a dog?变成否定句：I havn't got a dog.
She has got a ball.变为一般疑问句：Has she got a ball？变成否定句：She hasn't got a ball.
She has got some eggs.变为一般疑问句：Has she got any eggs?变成否定句：She hasn't got any eggs.
注意：some一定要在否定句与疑问句中变为any!
如果have表动词时：
如：吃……
I have dinner every day.变为一般疑问句：Do you have dinner every day?变成否定句：I don't have dinner every day.
He has lunch at half past one.变为一般疑问句：Does he have lunch at half past one?变成否定句：He doesn't have lunch at half past one.
注意：第三人称单数在提问时用does，后面动词用原型！(将谓语动词提前)
He speaks English 的疑问是 Does he speak English？变成否定句：He doesn't speak English.
像问题中列举的都属于一般现代时，详见一般现代时语法。

Answer 2

否定句用have not即havn't.
疑问句：Have somebody done something?
肯定回答：Yes,somebody have(第三人称单数时用has）
否定：No,somebody have not.（第三人称单数用has not)

He speaks English 的疑问是 Does he speak English？
