幾時用has/have ,, 幾時用is/are ??

has/have的意思是1)擁有 例子:i have a book.我有一本書. he has a pen.他有一支筆.
has是用于單人的(第二代名詞),例如:he,she,it,ali......
have是用于多人(第一代名詞),例如:i,you,we,they,the boys......
2)已經 例子:i have ate the breakfast.我已經吃了早餐. he has bought the books.他已經買了書.
has/have 後面一定要是past participle,past participle就是每個動詞的,例如:go>
gone,buy>bought,eat>ate.......這個是要用來背的,沒有方法,通常都是=動詞的past tense,但是有一些就是完全改變的,多數是+ed的,例如:i have opened the door.
但是如果你將has/have+is/are 來用的話,意思又不同了,他的意思會變成做,is/are的past participle是been,例子:i have been a doctor,我已經做了醫生.

is/am/are/was/were的意思都是1)是 例子:i am a girl,我是一個女孩,we are students.我們是學生.was/were是用在過去式(已經過去了的),例子:i was very happy.我很快樂(以前,現在沒有),如果講i am happy的話就是說我至今都很快樂.
am只是用在i而已,只有i am配在一起,永遠沒有you am,we am...沒有
is是用在he,she,it,ali......was也是,但是was是用在過去詞,例子:i was very happy yesterday.我昨天很快樂.
are是用在you,we,they,the boys......were也是,但是were是用在過去詞,例子:we were very happy yesterday.我門昨天很快樂.
2)做著 如果你要用做著這個意思就要把is/am/are/was/were的後面的動詞+ing 例子:she is reading a book.她讀著一本書 we are going to school.我們去著學校.注意:如果你沒有+ing的話,那你的句子就錯了,因為他的意思已經變了,她的意思是 被 例子:we are go to school.我們被走去學校,很好笑對吧,所以你要小心哦!!!

He/She/It就用has,is
I/We/They就用have,are
