【语法考点一】be动词的用法
在一般现在时中,be 动词有三种形式:am, is, are。其具体用法如下:
be动词现在有三兄弟:am, is, are
我(I)用am,你(you)用are,is连着他(he)她(she)它(it)。
单数名词用is,复数名词后用are。
变问句,be提前,句尾问号要配全。
Are you good friends?
(肯定句:You are good friends.你们是好朋友。are 放到you前面,变为一般疑问句。)
Is he tall and thin?
(肯定句:He is tall and thin.他又高又瘦。is 放到he前,变为一般疑问句。)
变否定,真容易,be后not为标记。
应用时,多注意,缩略形式要牢记。
I am = I'm You are = You're He is=He's She is =She's
They are =They're What is =What's is not =isn't are not=aren't
注意:this is 不可以缩写。
