威廉希尔app 为方便考生备考，特意整理了2014黑龙江七台河中考英语复习内容，愿天下备考人均能如意，而我，只愿面朝屏幕，继续码字……

1. Be动词的形式：

be现在过去

单数is/amwas

复数arewere

分词beingbeen

另外：我们还会碰到Be动词的动词不定式：to be，接下来我们来练练手吧 (光说不练假把式嘛)：

I am sorry for my ______ late today. I haven’t ______ late for a long time.

You must ______ here on time next time. I expect you ______ a punctual person.

答案：I am sorry for my being late today. I haven’t been late for a long time.

(原句意思是“很抱歉我今天迟到了。我很长时间没迟到了。” 所以这句话可别随便和你的老师说喔，不然老师一定会抽死你的。阴笑ing…)

You must be here on time next time. I expect you to be a punctual person.

2. Be动词的简写形式和否定形式：

简写形式：be动词的否定形式：be动词否定形式的简写：

I am => I’mI am not…I am… => I’m not…

You are => You’reYou are not…You are not… => You're not… => you aren't…

She is => She’sShe is not…She is not… => She's not… => she isn't…

注：如果be动词前有别的助动词的时候，要在be动词前面进行否定。换句话说当be动词是be, to be, being, been的形式时，否定都是在前面加not。

例如：It will not be that easy.

It couldn’t be better.

3. Be动词的进阶：

(1) 时态：进行时

be doing => am is are / was were doing

例句：She is writing a letter now.

I was sleeping at that time.

(2) 语态

be done (可以和各种时态结合)

例句：I am badly paid.

He was killed in an accident.

He is appointed as the manager of this department.

(3) 词缀be-

形容词：beloved adj. 敬爱的,受到爱戴的

belated a. 迟来的

benighted adj 愚昧无知的，落后的

动词：belittle vt. 轻视，使渺小

bemoan vt. 惋惜;为…叹息

4. 涉及的句型：

(1) 祈使句：

肯定：Be quiet, please.

Be carefull.

否定：Don’t be nervous.

Don’t be late.

Don't be too serious.

(2) There be 结构：

There are two books and a pen on the desk.

5. 句子赏析

Be yourself.

I'll always be there for you.

Leave her be, she obviously doesn’t want to talk about it.

To be or not to be，that’s the question.

【总结】虽然be动词很短小，但却很强悍，在英语各大语法重点中都有它的身影，如时态，语态，虚拟语气，反义疑问句，强调句，定语从句，倒装等语法现象，所以大家要好好掌握它的用法。
