6、動語態(tài)的基本時態(tài)變化 被動語態(tài)由“be及物動詞的過去分詞”構成，be隨時態(tài)的變化而變化。以do為例，各種時態(tài)的被動語態(tài)形式為：1) am/is/are +done (過去分詞) 一般現(xiàn)在時Visitors are requested not to touch the exhibits. 2)was/were done 一般過去時I was given ten minutes to decide whether I should reject the offer.完成時的被動語態(tài)加been 3) has /have been done 現(xiàn)在完成時All the preparations for

7、the task have been completed, and were ready to start.4) had been done 過去完成時By the end of last year, another new gymnasium had been completed in Beijing. 將來時的被動語態(tài)加be5) shall/will be done 一般將來時Hundreds of jobs will be lost if the factory closes.4、應用到各種時態(tài)和句型如下： 一般式（一般現(xiàn)在，一般過去，一般將來）：am, is, are, was, we

8、re, is going to be , will be+done.ie.I will mend the machine.相當于The machine will be mended 進行時（現(xiàn)在進行、過去進行）：be+being+P.P. ie.The classroom is being cleaned. 完成時（現(xiàn)在完成、過去完成）：have/has been + P.P.My homework has been finished. 其他時態(tài)依詞類推，可得到結果。 情態(tài)動詞的被動語態(tài)：主語 + 情態(tài)動詞 + be動詞 + 動詞過去分詞，例如Your teeth must be brushe

11、圖示法讓學生學習掌握各種時態(tài)被動語態(tài)用法，然后再結合練習進行口頭操練，鞏固練習，進一步促進學生對語言結構的綜合運用。但這堂課上下來也反映出很多的問題，由于課堂容量大，語法結構多，學生訓練較少，造成學生對被動語態(tài)運用較差。所以在今后的教學中還要進一步加強對語法的運用。一、 復習被動態(tài)時態(tài)及用法英語中及物動詞有兩種語態(tài)，即主動語態(tài)和被動語態(tài)。主動語態(tài)表示主語是動作的執(zhí)行者被動語態(tài)表示主語是動作的承受者。被動語態(tài)由“助動詞be+及物動詞的過去分詞”構成。助動詞be有人稱、時態(tài)和數(shù)的變化。 1.一般現(xiàn)在時被動語態(tài)構成：is / am / are + 及物動詞過去分詞 Our classroom is

12、cleaned everyday. I am asked to study hard. Knives are used for cutting things. 2.一般過去時被動語態(tài)構成：was / were + 及物動詞的過去分詞 A new shop was built last year. Dinosaur eggs were laid long long ago. 3.現(xiàn)在完成時的被動語態(tài)構成：has / have + been + 及物動詞的過去分詞 This book has been translated into many languages. 4.一般將來時的被動語態(tài)構成：w

13、ill+ be + 及物動詞的過去分詞A new hospital will be built in our city.Many more trees will be planted next year. 5.含有情態(tài)動詞的被動語態(tài)構成：情態(tài)動詞+ be + 及物動詞的過去分詞 Young trees must be watered often. Your mistakes should be corrected right now. The door may be locked inside. Your homework can be handed in tomorrow.二、怎樣把主動語態(tài)

14、改成被動語態(tài)?(新課講授) 把主動語態(tài)改為被動語態(tài)非常簡單，可以遵循以下幾個步驟： 1.先找出謂語動詞； 2.再找出謂語動詞后的賓語； 3.把賓語用作被動語態(tài)中的主語； 4.注意人稱、時態(tài)和數(shù)的變化。 例：1.Bruce writes a letter every week. A letter is written by Bruce every week. 2.Li Lei mended the broken bike this morning.The broken bike was mended by Li Lei this morning. 3.He has written two nov

15、els so far.Two novels have been written by him so far. 4.They will plant ten trees tomorrow.Ten trees will be planted by them tomorrow. 5.Lucy is writing a letter now.A letter is being written by Lucy now. 6.You must lock the door when you leave.the door must be locked when you leave.三、使用被動語態(tài)應注意的幾個問

16、題： 1.不及物動詞無被動語態(tài)。 What will happen in 100 years. The dinosaurs disappeared about 65 million years ago.2.有些動詞用主動形式表示被動意義。 This pen writes well. This new book sells well. 3.感官動詞或使役動詞使用省略to的動詞不定式，主動語態(tài)中不帶to ，但變?yōu)楸粍诱Z態(tài)時，須加上to 。 例：make somebody do somethingsomebody+ be +made to do something see somebody do s

17、omethingsomebody +be +seen to do something A girl saw my wallet drop when she passed by.My wallet was seen to drop by a girl when she passed by. The boss made the little boy do heavy work.The little boy was made to do heavy work by the boss. 4.如果是接雙賓語的動詞改為被動語態(tài)時，直接賓語(物)作主語，那么動詞后要用介詞，這個介詞是由與其搭配的動詞決定。

18、He gave me a book.A book was given to me by him.He showed me a ticket.A ticket was shown to me by him. My father bought me a new bike. A new bike was bought for me by my father. 5.一些動詞短語用于被動語態(tài)時，動詞短語應當看作一個整體，而不能丟掉其中的介詞或副詞。 We cant laugh him. He cant be laugh by us. He listens to the radio every day. The radio is listened to by him every day.The nurse is taking care of the sick man. The sick man is being taken care of by the nurse. 四、Exercises鞏固訓練(略)( ) 1 The Peo
