have, has 都是“有”,
它们的用法有讲究, 表示“某人有某物”，have, has请记住。 he, she, it “有”用has， I, we , they , you 都用 have。 主人单数用 has , 主人复数用 have。
have 就是能力强，疑问 （ ？）否定 （don’t / do not）都用它。
表示某人或某动物 有 ： has / have (I have a dog. The dog has a short tail.) 表示某地方 有： there is / are (There is a book in the bag. )
some用于肯定句中，any用于否定句和疑问句中。
如：I have some books. I don’t have any books. Do you have any books ?
一般来讲，元音字母（即a, e , i, o , u ）开头的单词用an
如： an apple an ear an American girl an Australian stamp an old man
意思： 表示某地方有某人或某物 原则：就近原则 （There be 句型中的be 动词用is 还是用are 由最靠近它的第一个名词是单数还是复数决定。）
如： There is a book and some pens on the desk. There are some pens and a book on the desk.
juice chalk tissue （不可数名词没有复数形式）
There is some chalk. There is some juice. There is some tissue.
表示：某人或某动物的
the girl’s name 那个女孩的名字 the teacher’s desk 讲台
the headmaster’s office 校长的办公室 the children’s toys 儿孩子们的玩具
the teachers’ room 教师办公室 (当名词的复数形式是以“s”结尾时，直接加 ’)
is are am （ 表示“是” ）
I 用am ， you 用are ， is 连着he，she ，it 。单数名词用is ，复数名词全用are 。 如： I am …. You are… . We are… . They are…. . He is….. She is….. It is…. The girl is …. The boys are…. Ben is…. Janet and Ben are…
