中考英語語法專項復習：被動語態(tài)

精品文檔中考英語語法專項復習：被動語態(tài)英語動詞有主動和被動兩種語態(tài)。主動語態(tài)表示主語是動作的執(zhí)行者,又叫施動者；被動語態(tài)表示主語是動作的承受者，又叫受動者。區(qū)分主動語態(tài)和被動語態(tài)，主要看主語是執(zhí)行者還是承受者。如：The flowers and grass should be watered .(_語態(tài))We should water the flowers and grass .(_語態(tài))一 構(gòu)成 1.被動語態(tài)是由“助動詞be +過去分詞”構(gòu)成的，助動詞be有時態(tài)、人稱和數(shù)的變化。Tom broke the cup .(主動語態(tài)) The cup was broken by Tom .(被動語態(tài))2.被動語態(tài)有以下8種：一般現(xiàn)在時：be(am / is are) +過去分詞 Trees are planted in spring .一般過去時：be(was / were) +過去分詞 The house was built last year .現(xiàn)在進行時：be(am / is are) + being +過去分詞 The car is being repaired .過去進行時：be(was / were) + being +過去分詞 現(xiàn)在完成時：have / has + been +過去分詞 The light has been turned off .過去完成時：had + been +過去分詞 一般將來時：will be +過去分詞 Lei Feng will be remembered by us forever .含情態(tài)動詞的：情態(tài)動詞+ be +過去分詞 My homework can be finished in two hours .3.被動語態(tài)常用于以下場合：不知道或沒有必要說明動作的執(zhí)行者是誰時。如：My bike was stolen yesterday .我的自行車昨天被偷了。強調(diào)動作的執(zhí)行者時，使用“by +動作的執(zhí)行者”。如：The pen was used by my father .這支鋼筆是我父親用過的。 只有及物動詞才有被動形式，不及物動詞如rise / come / go / take / place / happen等，沒有被動形式。二 主動語態(tài)變被動語態(tài)的步驟通常遵循以下三個步驟：1 把主動語態(tài)的賓語變成被動語態(tài)的主語。2 把主動語態(tài)的謂語動詞變?yōu)榕c其時態(tài)相對應的被動形式，且與被動語態(tài)的主語保持人稱和數(shù)的一致。3 將主動語態(tài)的主語變?yōu)榻樵~by的賓語，置于句末?！癰y +賓語”在句中常省略。主動語態(tài)：Many people speak English . 這里還需要連線！被動語態(tài)：English . is spoken by many people .如：Lu Xun wrote this book . This book was written by Lu Xun .這本書是魯迅寫的。 People are cutting down many trees now . Many trees are being cut down now .現(xiàn)在許多樹正被砍伐。三 主動語態(tài)和被動語態(tài)的轉(zhuǎn)換1.雙賓語的被動形式雙賓語的句子在變?yōu)楸粍诱Z態(tài)時，有兩種變法： 如果把指人的間接賓語變?yōu)橹髡Z，那么指物的直接賓語保留不動。如：His teacher gave him a book .He was given a book by his teacher . He has bought me a present .I have been bought a present . 如果要將指物的直接賓語變?yōu)橹髡Z，那么動詞后要用介詞to / for，這個介詞是由與其搭配的動詞決定的。如：His teacher gave him a book .A book was given to him by his teacher . He has bought me a present .A present has been bought for me . 常見的能接雙賓語的動詞有g(shù)ive / show / bring / lend / send等，這些詞與介詞to搭配；buy / make / draw等，這些詞與介詞for搭配。2.動詞短語的被動語態(tài) 許多不及物動詞加上介詞或副詞后構(gòu)成的短語動詞相當于及物動詞，是一個不可分割的整體，在變?yōu)楸粍诱Z態(tài)時不能把短語動詞分開，也不能漏掉短語動詞中的介詞或副詞。 如： We should speak to old men politely .Old men should be spoken to politely . He always takes care of his sister .His sister is always taken care of (by him). She turned off the radio .The radio was turned off (by her).3. 省略的to動詞不定式用于被動語態(tài) 在主動語態(tài)中，一些表示感官或使役的動詞，如hear / watch / see / feel / notice / listen to / look at / let /make / have和help等后面的賓語補足語是不帶to的動詞不定式，但句子在變?yōu)楸粍诱Z態(tài)后要加to。如： He made the girl stay at home .The girl was made to stay at home . We often hear her sing in the room .She is often heard to sing in the room . The boss made them work for 16 hours a day .They were made to work for 16 hours a day (by the boss).4. 主動形式表被動意義 動詞need，want以及短語be（well）worth等后面常接動名詞，以主動形式表示被動意義。如：The room needs cleaning .這房子需要打掃。 The piece of music is worth listening to .這首曲子值得聽。 某些表示主語質(zhì)地、自身特征的動詞，如write / wash / sell / clean / cook等，常和副詞well或easily連用，用主動形式表示被動意義。如：The cloth washes easily .這種布容易洗。 The pen writes well .這支筆很好用。練習一、用括號內(nèi)所給動詞的適當形式填空1.
