Be 动词专项练习

be动词的一般现在时有三种形式，即：am, is, are（翻译为“是”）

1. 如果主语是第一人称I（我）时，be动词用am。

如：I am a student. 我是一名学生。

I am 还可缩写成I'm。如：I'm David. 我是大卫。

am 与 not 不能缩写。如：I am not a bad boy.

2. 如果主语是you （你，你们）, they （他们，它们，她们）或名词复数 （两个以上的人或物）时，be动词必须用are。

如：Are you twelve? 你是十二岁吗？

Tom and Lily are good friends. 汤姆和莉莉是好朋友。

They are at school. 他们在学校。

are与主语还可缩写。如： We are= We're， They are =They're, You are = You're。而are与 not可缩写成aren't。如：They aren't students. 他们不是学生。

3. 如果主语是单数名词、不可数名词或单数第三人称代词（he, she, it）时，be动词用is。

如:My mother is a teacher. 我的妈妈是一名老师。

He is a student. 他是一名学生。

is也可与主语缩写,如: He is = He's, My mother is = My mother's等。但是This is不可缩写。而is与not可缩写成 isn't。如:This isn't a book. 这不是一本书。
