be動(dòng)詞的用法總結(jié)及練習(xí)題
學(xué)習(xí)英語的時(shí)候,很多人都是比較苦惱語法的學(xué)習(xí),就如be動(dòng)詞的用法就很多,下面是學(xué)習(xí)啦小編整理的一些關(guān)于be動(dòng)詞的用法總結(jié), 希望讓大家更好地認(rèn)識be動(dòng)詞,提高英語水平。
be動(dòng)詞的用法篇一
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。
be動(dòng)詞的用法篇二
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,對于不同人稱代詞以及單數(shù)名詞和復(fù)數(shù)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、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:
