举例说明如何把含有have和has的句子变成一般疑问句,如何作出肯定回答和否定回答

1 have / has 作为实义动词时，变一般疑问句在句子前面加do/ does （第三人称单数用Does )，后面的动词用原形(have ) 。
肯定回答是：Yes, ....do / does
否定回答是：No，……don't/ doesn't.
如
1) He has lunch at home every day .
一般疑问句：Does he have lunch at home every day ?
肯定回答：Yes, he does .
否定回答：No, he doesn't .
2）They have an English lesson every day .
一般疑问句： Do they have an English lesson every day ?
肯定回答：Yes, they do.
否定回答：No , they don't.

2. have / has 在现在完成时态中是助动词，变一般疑问句时，直接把have / has 提到句子前面
肯定回答是：Yes, .... have / has .
否定回答是： No, .... haven't / hasn't.
有时否定也可用简单回答：Not yet .
如
1) He has finished his homework .
一般疑问句：Has he finished his homework ?
肯定回答：Yes, he has .
否定回答：No, he hasn't.
或 Not yet .
2) We have been to Beijing .
一般疑问句：Have you been to Beijing ?
肯定回答：Yes, we have .
否定回答：No, we haven't.

或 Not yet .
3）They have had supper .
一般疑问句：Have they
