这个取决于人称和时态
特殊疑问句由特殊疑问词+ 助动词do/ does + have (+状语)构成。
What do they have? 他们有什么?
What does he have? 他有什么?
How many telephones do they have? 他们有几部电话?
What does he do on sunday?
What do you do on sunday?
What did he use to do ?
do作为助动词用法
1、一般疑问句
例句:Do you like English?
2、选择疑问句
例句:Does he go to school by bus or by bike?
3、特殊疑问句
例句:How do you go to school?
4、反义疑问句
例句:You like English， don't you?
5、否定句
例句:I don't like English.
用原型。
因为does提问第三人称单数，它是助动词。只要它在一般疑问句或特殊疑问句出现的时候，就要把动词变原型。
