be動(dòng)詞的用法總結(jié)及練習(xí)題1
英語的be動(dòng)詞是個(gè)用法比較復(fù)雜的動(dòng)詞。復(fù)雜的原因有兩點(diǎn)：
1、除了原形的be之外，對(duì)于不同人稱代詞以及單數(shù)名詞和復(fù)數(shù)名詞，be會(huì)有各種變化形式和縮寫形式。概括一下有七種形式：be, am, is, are, was, were, been, being。它們與人稱代詞和名詞單、復(fù)數(shù)的搭配關(guān)系是：
現(xiàn)在時(shí)I am, you are, he/she/it/ is, we/you/they are;名詞單數(shù)、不可數(shù)名詞用is，復(fù)數(shù)用are。
縮略式I'm, you're, he's, we're, you're, they're
否定縮略式I'm not, isn't, aren't
過去時(shí)I was, you were, he/she/it/ was, we/you/they were;名詞單數(shù)、不可數(shù)名詞用was，復(fù)數(shù)用were。
否定縮略式wasn't, weren't
過去分詞been
現(xiàn)在分詞being
2、在句子中，be有兩種主要作用：一是作為系動(dòng)詞(The Linking Verb)，本身可以作用謂語動(dòng)詞;二是做為助動(dòng)詞(The Auxiliary Verb)，與謂語動(dòng)詞一起構(gòu)成各種時(shí)態(tài)和被動(dòng)語態(tài)等。
下面做個(gè)簡(jiǎn)要的講解。
be動(dòng)詞的用法：做系動(dòng)詞
1、系動(dòng)詞+表語”的結(jié)構(gòu)
當(dāng)be動(dòng)詞做系動(dòng)詞使用時(shí)，主要構(gòu)成“系動(dòng)詞+表語”的結(jié)構(gòu)，在句子中做謂語。表語可以是名詞、形容詞、副詞、介詞短語等。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動(dòng)詞的一般疑問句，方法是把be移到主語前面，也可說成是移到句首。
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動(dòng)詞用在特殊疑問句
在特殊疑問句里，be動(dòng)詞仍然移到主語前面，但特殊疑問句是以特殊疑問詞開頭的，所以be動(dòng)詞只能說是移到主語前面，或者說是在特殊疑問詞的后面。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動(dòng)詞的否定句
be動(dòng)詞做謂語時(shí)，它的`否定形式是在be后加not，并且可以縮寫。例如：
It is not sunny today.
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動(dòng)詞的祈使句
be動(dòng)詞的祈使句有肯定和否定兩種形式�？隙ㄐ问绞且詁e動(dòng)詞開頭，而否定形式或強(qiáng)調(diào)句形，要加don't或do。例如：
Be careful!
Be a good boy!
Don't be silly!
Don't be a fool!
Do be obedient!
Do be careful.
be動(dòng)詞的用法：做助動(dòng)詞
助動(dòng)詞be有兩個(gè)基本用法，一是與謂語動(dòng)詞一起構(gòu)成各種時(shí)態(tài)，二是構(gòu)成被動(dòng)語態(tài)。
1、“be +現(xiàn)在分詞組”成各種進(jìn)行式時(shí)態(tài)。例如：

The children are playing in the field.
Samuel was eating when I came in.

be動(dòng)詞的用法：注意事項(xiàng)
英語句子中，為了表達(dá)時(shí)態(tài)或被動(dòng)語態(tài)的需要，常常會(huì)出現(xiàn)幾個(gè)助動(dòng)詞連在一塊兒使用。也就是說，助動(dòng)詞be會(huì)和其它助動(dòng)詞一起使用。這時(shí)候，整個(gè)句子的一般疑問句和否定句，就不一定是對(duì)be進(jìn)行變化了，而是以第一個(gè)助動(dòng)詞為主進(jìn)行變化。即哪個(gè)助動(dòng)詞在先，就以它為主進(jìn)行變化。例如：
[肯定句] All the wonderful birds can be found in our Bird Park. (助動(dòng)詞有兩個(gè)：can be )
[疑問句] Can all the wonderful birds be found in our Bird Park? (移第一個(gè)can)
[否定句] All the wonderful birds can not be found in our Bird Park. (在第一個(gè)can后加not)
[肯定句] I have been there before. (兩個(gè)助動(dòng)詞：have, been )
[疑問句] Have you been there before?
[否定句] I have not been there before.
[肯定句] I shall be having my supper at six tomorrow evening. (兩個(gè)助動(dòng)詞：shall, be )
[疑問句] Will you be having my supper at six tomorrow evening?
[否定句] I shall not be having my supper at six tomorrow evening.

be動(dòng)詞的用法總結(jié)及練習(xí)題2
1. Be動(dòng)詞有三個(gè)，am,is還有are.我用am,你用are, is跟著他她它，復(fù)數(shù)全部都用are.
如果遇到過去時(shí)，was來把a(bǔ)m,is替，were來把換掉動(dòng)詞are
2. do和be動(dòng)詞的用法區(qū)別
Be動(dòng)詞就是(am，are,is)..句子中如果沒有實(shí)意動(dòng)詞(例如:write，buy)之類的動(dòng)詞，就直接在主語后面加Be動(dòng)詞。而如果是句子中有實(shí)意動(dòng)詞，那么如果你要改為一般疑問句，就要借助DO(do也稱為助動(dòng)詞)，例如:I study.
改為一般疑問句:Do you study ?
順口溜：be氏三朵花, am, is還有are,
我(I)戀am,你(you)戀are,
is跟了他(he)她(she)它(it),
單娶is,復(fù)娶are。
