have的第三人称单数用在肯定句中是has:
例句:
He has a new car and a boat.
他有一辆新车和一条船。
have的第三人称单数用在否定句是have:
例句:
He does't have that much money on him.
他身上没带那么多钱。
have的第三人称单数用在疑问句是have:
例句:
Does he have a client named Peters?
他有一位名叫彼得斯的客户吗?
What does he have in his pocket?
他口袋里有什么东西?
第一人称单数,第二人称单数,第三人称单数依次为:I have a good friend.You have a good friend.She has a good friend.
补充:
否定第一人称单数为:I don't have a good friend. (这里因为have是动词,所以要找助动词do帮忙,因为是第一人称单数,所以要用do而不用does,因为是否定句,所以在助动词后加not.
补充:
否定第三人称单数为:She doesn't have a good friend. (这里因为have是动词,所以要找助动词does帮忙,因为she是第三人称单数,所以要用does而不用do,因为是否定句,所以在助动词后加not.
补充:
疑问句第一人称单数和第二人称单数都为Do you have a good friend? 第三人称为:Does she have a good friend?(在改疑问句时直接在肯定句中的前加上助动词,然后把动词变为原形即可.
补充:
一般改疑问句都是在肯定句的基础上改的,所以肯定句疑问的统一规则是:[助动词提前+人称变换(第一人称时变时换为第二人称)+动词原形]
你好。
have用于否定句,一般前面会有助动词,助动词do not(don‘t)遇第三人称单数变does not(doesn’t),have不变。
have用于疑问句,前面也一般有助动词,所以助动词do not(don‘t)遇第三人称单数变does not(doesn’t),have不变。
谢谢,希望能帮助到你,望采纳。
Thanks!!!
否定句:第三人称 hasn't 就是has not的缩写。
疑问句:Has 开头,例如Has she waked up yet?
在否定句和简单疑问句中
均有助动词do 如果是第三人称即为does
如 Why does he strongly object the decision of spending more time on extra curriculum?
或 He does not want to make decisions by himself.
