be動詞的用法總結及練習題
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,下面是本站小編整理的一些關於be動詞的用法總結, 希望讓大家更好地認識be動詞,提高英語水平。
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:I study.
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/they were;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 Auxiliary Verb),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.

助動詞be 有兩個基本用法,一是與謂語動詞一起構成各種時態,二是構成被動語態。
1、“be + 現在分詞組”成各種進行式時態。例如:
Tony's maid is washing his new car.
The children are playing in the field.
Samuel was eating when I came in.
We have been living here since 1959.
This time next day they will be sitting in the cinema.
be動詞的用法:注意事項英語句子中,爲了表達時態或被動語態的需要,常常會出現幾個助動詞連在一塊兒使用。也就是說,助動詞be會和其它助動詞一起使用。這時候,整個句子的一般疑問句和否定句,就不一定是對be 進行變化了,而是以第一個助動詞爲主進行變化。即哪個助動詞在先,就以它爲主進行變化。例如:
[肯定句] All the wonderful birds can be found in our Bird Park. (助動詞有兩個:can be )
[疑問句] Can all the wonderful birds be found in our Bird Park? (移第一個can)
[否定句] All the wonderful birds can not be found in our Bird Park. (在第一個can 後加not)
[肯定句] I have been there before. (兩個助動詞: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. (兩個助動詞: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.
助動詞be,無詞義,輔助主要動詞一起在句中作謂語動詞。用法如下:
1. be+doing:構成進行時態,有現在和過去兩種進行時態。如:
The girls is reading and copying the new words now.
Young Tom was always asking questions and trying out new ideas.
2. be+going to do,表示"打算或將要做某事",be有現在和過去兩種形式。如:
We are going to plant trees in the park.
I didn’t know if she was going to come here.
3. be+to do,表示"按計劃安排將要做某事"。如:
The new shop is not to be opened till next Monday. One night an angel came to
Mary and told her that she was to have this special boy.
be動詞的用法:there bethere be句式爲:there be+主語部分+狀語部分,表示"某處存在某物",be常用現在時,過去時和將來時等。如:
Oh, cool! And there are many things to see. There is even a deer park in Sanya.
There are about 80 pyramids in Egypt.
Will there be a football match in your school next week?
be動詞的用法:實義be可以將be視爲實義動詞,因爲它具有實際的詞義,如"成爲;做;發生;舉行;逗留;到達"等。如:His daughter wants to be a doctor for animals in her s birthday party
will be at half past six this has been in China for
morethan two years, but he has not yet been to Yichang.
