单数第三人称的时候用has,其它人称都用have.

一般现在时的情况下,主语是第三人称单数用has,主语是第一人称,第二人称,第三人称复数用have

has have had 的用法:

后接过去分词,构成现在和过去完成、完成进行时。例如:
a) He has gone to Beijing. 他已经到北京去了。
b) I have been a teacher since then. 从那时起我就一直当教师。
c) They had left when I got there. 我到那里的时候,他们已经走了。
d) He has been working hard since early morning. 丛一大早他就一直在下劲干活。
注: has have had也可以作为一般动词,意为“拥有”“进行”“吃”“使得”“让”等。如果后接不定式,意为“不得不”。因为它们不是特殊动词,所以不能在它们后面加not构成否定句,不能把它们移到句首构成疑问句。例如:
a) He has a good pen. 他有一支好笔。
b) We have supper at 6:00. 我们六点钟吃晚饭。
c) I had my hair cut yesterday. 我昨天理了发。(我让我的头发被剪了,昨天)
d) I have to leave now. 我得走了。

has和第三人称单数一起用, have用在其他非三人称单数时候:

例如:
He has finished his job!
She has a new teacher today.
It has not rained for a long time.

I have finished my job!
They have a new teacher today.

1.在现在时态中,has用于第三人称单数(如he,she it等),其余人称都用have(如第一、二人称的单复数,第三人称复数)
I have a new pen now(现在).
He has a new pen now(现在).
2.注意:这些也看作第三人称单数(但以下词必须首先是单数,即没有加有S等):
my friend (因为可把它看作he或she ),the book, my cat (因为可把它看作it).
My friend has a new pen.
My cat has two beautiful ears.
3.my friends, the books(因为可把它看作they-它们),故其后应用have.
My friend have new pens.
