口诀：现在状态主系表，系词be要用好，我用 am, you用are,
单数is，复数are。be若提前变疑问，be后not变否定。
解读：描述主语现在状态的句子，就用主系表结构。
陈述句语序：主语+ 系动词（be）+ 表语。表语是用来说明主语是什么、怎么样的，说明主语的身份、特征或状态
Tom is an English boy.
My hobby is reading .
Five plus two is seven .
This flower is beautiful.
I am fine .
We are here .
He is not at home .

其他的系动词 如feel ,look ,sound ,taste ,smell ，grow , get，turn，
become 在用法上与实义动词一样，在变成否定句和疑问句时要接助动词。
此处不讲 ,放在实义动词部分讲。
新知讲解
含有be的一般现在时的句型变换
含有be的一般现在时的肯定句在变成否定句及疑问句时可遵从以下规则：be若提前变疑问，be后not变否定。（含有some的肯定句在变成否定句的同时把some变成 any；同时注意第一人称与第二人称的互变）。

肯定回答：Yes,I am. 否定回答: No,I’m not.
②He is a student.
否定句： He isn’t a student. 疑问句： Is he a student
肯定回答：Yes,he is. 否定回答：No,heisn’t.
