will/can/could/would/should/shall 等助动词后面加be
其他时候, 第一人称I后面用am
第二人称, 复数, 用are
单数用is...
be动词其实就是am is are was wrer 的总称
有只要以上的5个，其中一个加入主语后面。
这就是一个有be动词的句子。
呵。。。。。。
am,is are 都属于be动词，be是他们的原型
be动词的一般现在时有三种形式，即：am, is, are。
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。
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。但是am与not不能缩写。
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。
根据以上叙述我们可以把动词的用法以口诀的形式表述出来：
我（I）是am,
你（you）是are,
剩下is留给她（she）, 他（he）, 它（it）,
两个以上都用are。
