如果把have作为现在完成时的标志,规则是:把have 或has提前到句首,其余不变。例证:
1) I have won the football match before I leave school.→Have you won the football match before I leave school?回答:Yes, I have.
2) She has finished her homework.→Has she finished her homework?回答:Yes,she has./No,she hasn't.
如果把have(has)当作实义动词,那么规则是:方法一:将have或者has提前到句首,其余部分不变。
具体举例如下:1) You have a football.→Have you a football?
2) He has classes tomorrow.→Has he a football?
方法二:在句首加Do(当用have时)或does(当用has时),其余部分不变。
举例:1) You have a football.→Do you have a football?
2) He has classes tomorrow.→Does he has classes tomorrow?
其他动词原形的句子把动词当成have来用即可,但是只能用方法二。
否定句一般来说只要在动词前面加don't或doesn't即可。举例:
1) I have a football.→I don't have a football.
2) He loves studying.→He doesn't love studying.
对划线部分提问,划线部分是地点、时间、人物,分别用Where/When/Who代替划线部分,并把它放在句首即可。
例如:
1) She met James in the street(划线)yesterday.→Where did she meet James yesterday?
2)She met James(划线)in the street yesterday.→Who did she meet in the street yesterday?
3) She met James in the street yesterday(划线).→When did she meet James in the street?
主语是第一第二人称(I,you)或者复数(we,they)时,用have
主语是第三人称(he,she,it)时,用has
He has a pen.
一般疑问句: Does he have a pen?
对划线提问(划的应该是a pen): What does he have?
否定句: He does not have a pen.
注意主语是我(I)时的变化:
I have a pen
一般疑问句: Do you have a pen?
对划线提问(划的应该是a pen): What do you have?
否定句:I don't have a pen.
要把原句中的I换成you
有两种变法:1、把has 或have 放在句首,其他成分的位置不变。比如:He has a dog变成一般疑问句就是Has he a dog?
2. 用does/do。上面的句子也可以变成Does he have a dog?
have has 变否定是haven't。一般疑问就是直接have 提前。划线提问看词的成分。
句式一样,不过have用助动词用do,has用助动词does!
祝更上一层楼!
