6.be动词的用法:
我(I)用am,你(you)用are, is连着他(he),她(she),它(it);
这些是固定用法:
I am a boy. (你不能说 I is a boy)
You are a student.
He is a boy.
She is a girl.
It is a cat.
单数名词用is,复数名词全用are。(主语个数是一个时,谓语用单数is,主语个数为2个或以上,谓语用复数are.)如:
The book is over there.(一本书)
The books are over there.(多本书)
变疑问,往前提,句末问号莫丢弃。(陈述句中谓语为is,are,am时,变疑问句只将其提前)如:
It is a book.变为:Is it a book?
变否定,更容易, be后not莫忘记。如:
It is a book.变为: It is not a book.(否定句)
疑问否定任你变,句首大写莫迟疑。如:
It is a book.变为:Is not it a book?(疑问否定句)
Eg: 用am, is ,are 填空。
