②单数概念主语用is, 复数概念主语用are

用Be动词（am, is, are) 填空：
am a student. I____
is Jack. My name____
is my sister. She____
are my friend. You____
is an apple. It____
is yellow. It____
is a nice girl. She_____
They are my parents.
③变否定，也容易， be 后not加上去
I am a teacher.变为否定句： I am not a teacher. You are my friend.变为否定句： You are not my friend. Tom is his brother. 变为否定句： Tom is not his brother. They are my parents. 变为否定句： They are not my parents.
④主系表结构句子要变为一般疑问句， be 前提，句末问号莫丢弃 一般疑问句：用 Yes或No来回答的句子
This is my sister. 变为一般疑问句： Is this your sister?
Yes, she is./ No, she is not. (is not 缩写为isn’t)
These are my parents.变为一般疑问句：
主语是一句话的中心，，其位置一 般放在句首，主语主要由名词、代 词，动名词或起名词作用的短语或 从句来充当。 eg: Li Lei is a Chinese boy .(Li lei 是名词，作主语) eg: He is from England .(He是 代词，作主语)
Be 动词: am, is, are ① 我( I) 用am, 你(you)用are, is 连着他(he)、 她(she)、它(it)
is a boy. He____ are my parents. They_____ are friends. Tom and Peter______ are very happy. My parents____ are in Kunming. We_____

表语： 表语和Be动词一起用来修饰主语，说明主 语的身份、性质、品性、特征和状态的，表 语位于系动词之后。表语一般是名词，形容 词，介词短语,代词等。

It is an apple. It is a pen. It’s an orange.
It is yellow. It is black. It is orange. My friend is in China. This book is mine.
