be動詞的用法整理
學習英語的時候，很多人都是比較苦惱語法的學習，就如be動詞的用法就很多，下面給大家分享一些關於be動詞的用法整理，希望對大家有所幫助。
be動詞的用法篇一
1. Be動詞有三個，am,is還有are.我用am, 你用are, is跟着他她它，複數全部都用are.
如果遇到過去時，was來把am,is替，were來把換掉動詞are
2. do和be動詞的用法區別
Be動詞就是(am，are,is)..句子中如果沒有實意動詞(例如:write，buy)之類的動詞，就直接在主語後面加Be動詞。而如果是句子中有實意動詞，那麼如果你要改爲一般疑問句，就要藉助DO(do也稱爲助動詞)，例如:Istudy.
改爲一般疑問句: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, 復娶are。
be動詞的用法篇二
英語的be 動詞是個用法比較複雜的動詞。複雜的原因有兩點：
1、 除了原形的 be 之外，對於不同人稱代詞以及單數名詞和複數名詞，be 會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、複數的搭配關係是：
現在時 I am, you are, he/she/it/ is, we/you/they are;名詞單數、不可數名詞用is，複數用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 I was, you were, he/she/it/ was, we/you/theywere;名詞單數、不可數名詞用was，複數用were。
否定縮略式 wasn't, weren't
過去分詞 been
現在分詞 being
2、在句子中，be有兩種主要作用：一是作爲系動詞(The Linking Verb)，本身可以作用謂語動詞;二是做爲助動詞(The AuxiliaryVerb)，與謂語動詞一起構成各種時態和被動語態等。
下面做個簡要的講解。
be動詞的用法：做系動詞
1、系動詞+表語”的結構
當be 動詞做系動詞使用時，主要構成“系動詞+表語”的結構，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 動詞用在特殊疑問句
在特殊疑問句裏，be 動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動詞只能說是移到主語前面，或者說是在特殊疑問詞的後面。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 動詞的否定句
be 動詞做謂語時，它的否定形式是在be 後加not，並且可以縮寫。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 動詞的祈使句
be 動詞的祈使句有肯定和否定兩種形式。肯定形式是以be 動詞開頭，而否定形式或強調句形，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.
