1、第七單元語法知識及練習(xí)題,現(xiàn)在完成時的被動語態(tài),1.掌握現(xiàn)在完成時被動語態(tài)的構(gòu)成 現(xiàn)在完成時被動語態(tài)的結(jié)構(gòu)為hashave been done, 使用has been done時主語為單數(shù), 使用have been done時主語為復(fù)數(shù)。 This book has been translated into many l languages. 這本書已被譯成多國語言。 His bikes have been sold out. 他的自行車已都賣完了。,2. 理解現(xiàn)在完成時被動語態(tài)的概念 現(xiàn)在完成時被動語態(tài)強(qiáng)調(diào)一個發(fā)生在過去的被動 性動作, 它有兩層意思: 動作已經(jīng)完成, 強(qiáng)調(diào)對現(xiàn)在造成的影響或

2、結(jié)果。 主語與謂語動詞之間為被動關(guān)系。 Our classroom has been cleaned, you neednt clean it now. 我們的教室已被打掃過, 你現(xiàn)在沒必要再打掃了。 These flowers have been watered, you can go home. 這些花已被澆水了, 你可以回家了。,特點(diǎn)： 1. 主語是行為動作的承受者。如： The Great Wall has been rebuilt. 長城已經(jīng)過重建。 2. 說話時已經(jīng)完成的動作或出現(xiàn)的結(jié)果。如: The door has been locked. 門已經(jīng)被鎖上了。 （我或別人現(xiàn)在進(jìn)不

3、去）,3. 動作或狀態(tài)始于過去, 持續(xù)到現(xiàn)在, 并可能持續(xù)下去。如： He has been told about it for many times. 有人告訴他這事很多次了。（可能還會有人告訴他） 4. 用在時間和條件狀語從句中，表示將來某時已 完成的動作。如： Well start as soon as the work has been finished. 工作一完成我們就立即動身。,3. 現(xiàn)在完成時被動語態(tài)的用法 (1) 用于不知道動作執(zhí)行者是誰時。 His bikes have been stolen. 他的自行車被人偷了。 (不清楚是誰偷的) (2)用于動作執(zhí)行者是泛指或不言自明

4、時. Not a book in the library has been taken away. 圖書館里的書沒有一本被人拿走。 (沒人拿書, 泛指),(3)用于可以說出動作執(zhí)行者, 但動作承受者是談 話中心或特別需要強(qiáng)調(diào)時。 My watch has been repaired. 我的表修好了。 (表修好了是談話的主旨, 是誰修好無關(guān)緊要, 不 必提及) (4)用于出于委婉禮貌而避免提及自己或?qū)Ψ?時。 Enough has been said here on this question. 關(guān)于這個問題, 這里已經(jīng)談得不少了。 (意思是: 大家不要再說了),(5)用于文章標(biāo)題、廣告、新聞等

5、, 常用省略助動 詞be的被動語態(tài)。 Road Blocked. 道路已被堵塞。 (新聞報道, 省略了助動詞has been。) (6)用于動作的執(zhí)行者不是人時。 The house has been washed away by the storm. 那幢房子已被暴風(fēng)雨沖走了。 (7)用于商務(wù)書信中起草人是以公司名義時。 Your letter has been received. 來信已收到。,4. 現(xiàn)在完成時被動語態(tài)的各種句型變換 從現(xiàn)在完成時被動語態(tài)結(jié)構(gòu)hashave been done 可以看出hashave為助動詞, 因此現(xiàn)在完成時被動 語態(tài)的各種句型變換均應(yīng)借助hashave來完

6、成。 構(gòu)成否定句時直接在hashave后面加not, 構(gòu)成一 般疑問句時將hashave提前。 Has this bridge been finished? 這座橋竣工了嗎? His homework hasnt been finished 他的家庭作業(yè)還沒有寫完。 The black board has been cleaned, hasnt it? 黑板已擦過了, 是嗎?,注意點(diǎn) 1. 副詞的位置 often, usually, always, never, hardly, seldom 等頻度副詞置于have/has和been中間。如： 誤 Such a man has been har
