【Be動詞例句】
be動詞的一般現在時有三種形式,即:am,is,are.1.如果主語是第一人稱I(我)時,be動詞用am.如:I am a student.我是一名學生.I am 還可縮寫成I'm.如:I'm David.我是大衛.2.如果主語是you (你,你們),they (他們,它們,她們)或名詞復數 (兩個以上的人或物)時,be動詞必須用are.如:Are you twelve?你是十二歲嗎?Tom and Lily are good friends.湯姆和莉莉是好朋友.They are at school.他們在學校.are與主語還可縮寫.如:We are= We're,They are =They're,You are = You're.而are與 not可縮寫成aren't.如:They aren't students.他們不是學生.但是am與not不能縮寫.3.如果主語是單數名詞、不可數名詞或單數第三人稱代詞(he,she,it)時,be動詞用is.如:My mother is a teacher.我的媽媽是一名老師.He is a student.他是一名學生.is也可與主語縮寫,如:He is = He's,My mother is = My mother's等.但是This is不可縮寫.而is與not可縮寫成 isn't.如:This isn't a book.這不是一本書.根據以上敘述我們可以把動詞的用法以口訣的形式表述出來:我(I)是am,你(you)是are,剩下is留給她(she),他(he),它(it),兩個以上都用are.[思路分析]be作助動詞用的形式如下:①am,is,are,was,were②助動詞+be:shall be,will be,can be,etc.③have/has/had + been(完成時)④am,is,…being(進行時) [解題過程](1)表達進行時態句型 be + V-ing…(進行時態)例:What are you reading?(你正在閱讀什么?)I am reading a magazine.(我正在閱讀雜志.)例:He will be taking a walk in the park at this time tomorrow morning.(明天早晨此時他將會正在公園散步.)例:She has been teaching English in our school for years.(她已在我們學校教英語許多年了.)解說 第一例句是表達現在進行時,第二例句是將來進行時,第三例句是現在完成進行時.(2)表達被動語態句型 be +p.p.…(被動語態)例:English is spoken in both Canada and the United States.(加拿大和美國都講英語.)例:Those keys were found in your drawer.(那些鑰匙是在你的抽屜里找到的.)例:It can be done much faster in this way.(這件工作用這個方法可以更加快速地做好.)。
be動詞用法與例句
be是一個連系動詞,它有自己不同的形式 現在時:be 進行時:being 過去時:was/were 過去分詞:been 它的后面必須跟形容詞或名詞作表語,與之構成系表結構,充當句子的謂語。
i am a student主語:i 謂語:am a student(系表結構) being是它的現在進行時態,一般不單獨用,而是用于現在進行時的被動語態。(being+動詞過去分詞) the bike is being repaired.單車正在被修理中。
it is being finished by him這正在被他完成中。 been是它的過去分詞,也不一般單獨使用,而是用于現在完成時、過去完成時以及需要它的句子。
i have been here for a long time.我已經到這里有一段時間了。 至于你的問題,這與你想表達的意思有關。
你的工作是什么? what do you do? what is your job? 那么這里選用do和is有什么根據呢? 第一句里面,第二個do是指你做什么,也就是你的工作,就是一個實義動詞。按中文說,what you do已經足夠了。
可是英語里面就不行,必須跟一個助動詞,也就是do. 這里就有了一個結論:當句子中有動詞時,我們就用助動詞do或是does.如果沒有動詞時,我們就選用is或是are,也就是b“Be”除了原形的“be”之外,還有另外七種形式:am, is, are, been, being, was, were. 在句子中,“be”可以是主動詞(The Principal Verb)或助動詞(The Auxiliary Verb). 當主動詞時,“be”在性質上屬于接系動詞(The Linking Verb), 后面要有名詞、形容詞、地方副詞或短語作補足語(The Complement)。例如: 1. The man is a science teacher. 2. Mary's new dresses are colourful. 3. I have been there before. 4. Mother is in the kitchen now. 這四個都是陳述句,可以變成疑問句,方法簡單,把主語和“be”或助動詞對換位置即可: 5. Is the man a science teacher? 6. Are Mary's new dresses colourful? 7. Have I been there before? 8. Is mother in the kitchen now? 當“be”要在祈使句中出現時,它必須借重助動詞“do”或“don't”之助,如: 9. Don't be silly! 10. Do be obedient! 11. Don't be a fool! “Be”有兩種縮寫法,如下: 12. He's not。
../He isn't。. 13. You're not。
../You aren't。 但“am + not”的縮寫法只有一個: 14. I'm not. 有人用“ain't”, 但這并不是標準英語。
談過了“be”作主動詞的功能,現在看看“be”作助動詞時,有些什么用法: 1.“Be + 現在分詞”以組成進行式時態(Continuous Tenses),如: 15. Tony's maid is washing his new car. 16. The children are playing in the field. 17. Samuel was eating when I came in. 18. We have been living here since 1959. 2.“Be + 過去分詞”以組成被動語態(The Passive Voice),如: 19. Her money in the drawer was stolen. 20. A number of good jobs are taken up byforeigners. 21. David studied in Taiwan but has been trained as a language lecturer in America. 22. Can all the wonderful birds be found in our Bird Park? 23. The disobedient boy was told to stand out- side the classroom. 24. Steps are being taken to reduce traffic con- gestion during peak hours. 25. Dishonest students will be immediately dealt with.。

英語造句如何用BE動詞和助動詞
What you have said does not relate to what we are concerned with now. (注:原題的標點符號有誤)
英語中,改否定句或疑問句時,應該注意用好be動詞、情態動詞、助動詞。規律是:先找be、情、助,無則“都打的(do, does, did)”。
即:1、如果原句中有be動詞、情態動詞或者助動詞,就以相應的be、情、助為準。例如:
(1)He is at home. (有be動詞)
He isn't at home.
Is he at home?
(2)I can work it out.(有情態動詞)
I can't work it out.
Can you work it out?
(3)He has been there three times.(有助動詞)
He hasn't been there three times.
Has he been there three times?
2.如果原句只有行為動詞,那就要借助于助動詞do,did或者did。例如:
(1)My grandpa lives in a villige.(注意動詞還原)
My grandpa doesn't live in a villige.
Does your grandpa live in a villige.
(2)They had a good time there.(注意動詞還原)
They didn't have a good time there.
Did they have a good time there?
(3) We work six hours a day.
We don't work six hours a day.
Do you work six hours a day?
您的這個句子的主語是What you have said ,即一個主語從句,從句子中我們知道謂語部分要用一般現在時態,故謂語動詞要用現單三形式。
不知這樣解釋可否?

There is nothing to see (=to be seen).看不見有什么。 There is nothing to do.(=to be done) 無事可做。
