2、結(jié)果。 主語與謂語動(dòng)詞之間為被動(dòng)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(dòng)作的承受者。如： The Great Wall has been rebuilt. 長(zhǎng)城已經(jīng)過重建。 2. 說話時(shí)已經(jīng)完成的動(dòng)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(dòng)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(huì)有人告訴他） 4. 用在時(shí)間和條件狀語從句中，表示將來某時(shí)已 完成的動(dòng)作。如： Well start as soon as the work has been finished. 工作一完成我們就立即動(dòng)身。,3. 現(xiàn)在完成時(shí)被動(dòng)語態(tài)的用法 (1) 用于不知道動(dòng)作執(zhí)行者是誰時(shí)。 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(dòng)作執(zhí)行者是泛指或不言自明

4、時(shí). 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(dòng)作執(zhí)行者, 但動(dòng)作承受者是談 話中心或特別需要強(qiáng)調(diào)時(shí)。 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(shí)。 Enough has been said here on this question. 關(guān)于這個(gè)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(dòng) 詞be的被動(dòng)語態(tài)。 Road Blocked. 道路已被堵塞。 (新聞報(bào)道, 省略了助動(dòng)詞has been。) (6)用于動(dòng)作的執(zhí)行者不是人時(shí)。 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(shí)。 Your letter has been received. 來信已收到。,4. 現(xiàn)在完成時(shí)被動(dòng)語態(tài)的各種句型變換 從現(xiàn)在完成時(shí)被動(dòng)語態(tài)結(jié)構(gòu)hashave been done 可以看出hashave為助動(dòng)詞, 因此現(xiàn)在完成時(shí)被動(dòng) 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(shí)直接在hashave后面加not, 構(gòu)成一 般疑問句時(shí)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
