        少兒英語(yǔ)語(yǔ)法:be動(dòng)詞的用法口訣和詳解

        字號(hào):

        這篇關(guān)于少兒英語(yǔ)語(yǔ)法:be動(dòng)詞的用法口訣和詳解,是特地為大家整理的,希望對(duì)大家有所幫助!
            be 的用法口訣
            我用am,你用are,is連著他,她,它;
            單數(shù)名詞用is,復(fù)數(shù)名詞全用are。
            變疑問(wèn),往前提,句末問(wèn)號(hào)莫丟棄。
            變否定,更容易,be后not莫忘記。
            疑問(wèn)否定任你變,句首大寫(xiě)莫遲疑。
            be動(dòng)詞的用法:be (be/is/are/am/was/were)
            vi
            現(xiàn)在時(shí) I am, you are, he is, we are, you are, they 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(guò)去時(shí) I was, you were, he was, we were, you were, they were (過(guò)去時(shí)否定縮略式 wasn't, weren't), 過(guò)去分詞been, 現(xiàn)在分詞being
            英語(yǔ)的“be”是個(gè)特殊動(dòng)詞;有些語(yǔ)言,如馬來(lái)文等,并沒(méi)有“be”這樣的動(dòng)詞。
            “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(dòng)詞(The Principal Verb)或助動(dòng)詞(The Auxiliary Verb)
            例句對(duì)照
            【當(dāng)主動(dòng)詞時(shí),“be”在性質(zhì)上屬于接系動(dòng)詞(The Linking Verb), 后面要有名詞、形容詞、地方副詞或短語(yǔ)作補(bǔ)足語(yǔ)(The Complement)。例如:
            1. The man is a science teacher.
            這個(gè)男子是一位科學(xué)教師
            2. Mary's new dresses are colourful.
            瑪麗的新衣服色彩鮮艷
            3. I have been there before.
            我以前去過(guò)那里
            4. My mother is watching TV in the room.
            母親現(xiàn)在在客廳看電視 
            【這四個(gè)都是陳述句,可以變成疑問(wèn)句,方法簡(jiǎn)單,把主語(yǔ)和“be”或助動(dòng)詞對(duì)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(dāng)“be”要在祈使句中出現(xiàn)時(shí),它必須借重助動(dòng)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(xiě)法,如下:
            12. He's not...../He isn't....
            13. You're not...../You aren't...
            【但“am + not”的縮寫(xiě)法只有一個(gè):
            14. I'm not.
            有人用“ain't”, 但這并不是標(biāo)準(zhǔn)英語(yǔ)。
            談過(guò)了“be”作主動(dòng)詞的功能,現(xiàn)在看看“be”作助動(dòng)詞時(shí),有些什么用法:
            【1.】“Be + 現(xiàn)在分詞”以組成進(jìn)行式時(shí)態(tài)(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.】“情態(tài)動(dòng)詞+Be + 過(guò)去分詞”以組成被動(dòng)語(yǔ)態(tài)(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.
