Be 动词的用法口诀
我⑴用am你(you)用are ,
is 连着他(he)、她(she)、它(it)。
单数名词用is ，复数名词全用are。
变疑问，往前提，句末问号莫丢弃。
变否定，更容易，be 后not 莫忘记。
疑问否定任你变，句首大写莫迟疑。
1.我⑴ 用am,你(you)用are,is 连着他(he),她(she),它(it);
这些是固定用法：

(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.) The book is over there.（一本书）
The books are over there. 多本书）
They/We/You are students.
3．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?
They are students. 变为：Are they students?
I am a student. 变为: Are you a student?（第一、第二人称要互换，be 动词也相应变化。

It is a book. 变为: It is not a book.（否定句）
They are students. 变为：They are not students.
I am a student. 变为: I am not a stuent.
5．疑问否定任你变, 句首大写莫迟疑. 如：
