▲▲▲主语表示单数时用has,主语表示复数时用have,如以下常用搭配:
(1)He has an apple. (2)She has an apple.
(3)It has a long nose.(he/she/it是第三人称单数) (4)The cat has small ears.(the cat 是单数) (5)The cats have small ears.(the cats 是复数)

(9)The man has a blue bag. (10)That woman has a good friend.(that woman 是单数) (11)Mike has an apple.(Mike是单个人名,作单数)
(12)Miss Li has a red bag.(Miss Li 是称呼,是第三人称单数) (13)They have two new students.(they他们,是复数) (14)We have a new teacher.(we意思是我们,是复数,谓语动词用原形。)
总结:主语是第三人称单数时,谓语动词要用第三人称形式。have是动词原形,has就是have的第三人称单数形式。 问:什么是第三人称单数?
①人称代词he/she/it是第三人称单数。He is a student. ②单个人名(如Mike/Amy等)、地名(如Beijing等)、称呼(如Uncle Wang/Miss Li等)作主语,是第三人称单数。 Mike is a student. Beijing is in China. Uncle Li is a teacher.
③单数可数名词或“this/that/the+单数可数名词”作主语时,是第三人称单数。如:(this man/that woman/this boy/that girl/the man/the student/the book/the cat) This man is my father. That boy is my friend. The book is red. The cat is so fat.
④数字或字母作主语时,看作第三人称单数。 “I”is a letter(字母)。

The bread is so small.(the bread、the cake 是不可数名词) 7.对新朋友表示欢迎:Welcome! Unit2

3. A: 当你要鼓励你的朋友一起和你玩时,英语怎么说: B: Come on!
4. A: Let’s watch TV. B:OK!/Great! Let’s =Let us(let后跟人称代词宾格)
