动词be(is,am,are)在英语的学习过程当中，离不开它的使用,将它的使用方法编成一个顺口溜，记忆起来更容易。
我(I)用am,,
你you用(are),
is跟着他(he),她(she),他(it).
单数名词用is，
复数名词全用are。
例如:
I am a student
You are a teacher
He is my father.
She is my mother.
It is my dog.
The book is on the desk
There are five people in my family
变否定，更容易，
be后not加上去。
变疑问，往前提，
句末问号莫丢弃。
还有一条须注意，
句首大写别忘记。
例如:
He isn't at home.
We're not robots.
I am not a pupil.
Are you in Beijing now?
Is she your sister?
