初中英语Be动词定义及用法:
1、系动词+表语”的结构
当be 动词做系动词使用时，主要构成“系动词+表语”的结构，在句子中做谓语。表语可以是名词、形容词、副词、介词短语等。例如:
The man is a science teacher.
Mary's new dresses are colourful.
Mother is in the kitchen now.
I have been there before.
They shall be here at 10:00 tommorow.
That can't be true.
You are not being very polite.
Your brother is being very annoying this evening
2、be 动词的一般疑问句，方法是把be 移到主语前面，也可说成是移到句首。
Is the man a science teacher? Yes, he is. / No, he isn't.
Are Mary's new dresses colourful? Yes, they are. / No, they aren't.
Was mother in the kitchen then? Yes, she was. / No, she wasn't.
Were you at home the day before yesterday? Yes, I was. / No, I wasn't.
Was she late this morning? Yes, she was. / No, she wasn't.
3、be 动词用在特殊疑问句
在特殊疑问句里，be 动词仍然移到主语前面，但特殊疑问句是以特殊疑问词开头的，所以be 动词只能说是移到主语前面，或者说是在特殊疑问词的后面。例如:
Whose bike is broken? Xiao Ming's bike is.
Who was singing in the room? Mr. Zhang was.
Where are you from? I am from Wuhu.
What class were you in? We were in Class 2.
How old is Tom? He is ten.
4、be 动词的否定句
be 动词做谓语时，它的否定形式是在be 后加not，并且可以缩写。例如:

Tom and his friends are not in the park.
You were not nine years old when I went to the university.
He was not often late for his class when he was a student.
I wasn't here yesterday.
My parents weren't at home last Sunday.
5、be 动词的祈使句
be 动词的祈使句有肯定和否定两种形式。肯定形式是以be 动词开头，而否定形式或强调句形，要加don't 或do。例如:

Don't be silly!
Don't be a fool!
Do be obedient!
Do be careful.

初一英语动词用法的顺口溜:
一、be动词的用法:
我用am，你用are，is连着他，她，它;
单数名词用is，复数名词全用are。
遇上一般过去时; are变were不用怕。
am，is变was. be是原形老妈妈。
not靠后变否定; be跑句首去问它。
二、人称代词的用法
人称代词主宾格，作用不同莫用错。
主格动词前做主，动词介词后宾语。
You和it主宾同，其他主宾需分清。
人称代词并列现，尊重他人礼当先。
单数人称二三一，复数人称一二三。
若把错误责任当，第一人称我靠前。
三、情态动词的用法
情态动词要记牢;动词原形来跟梢。
不管人称单复数;现在过去乐逍遥。
can表能力和许可;也许可能may来表;
必须一定must;should应该来报到。
回答不须needn’t;mustn’t为不必要。
否定只要接not;疑问赶紧往前跑。
四、助动词的用法
助动词，用法怪;只当佐料不当菜。
句型变换显身手;常与时态谈恋爱。
have完成be进行;will将来三大块。
加上各自过去式;总共构成六时态。
否定疑问靠它们;用法如同be相待。
一般现在和过去;没有助动也无碍。
否定疑问照常变;过去did， do现在。
第三人单用does;遵守be法和情态。
