2、tep 3. Introduce Passive Voice 語語法：被動(dòng)語態(tài) 一、 主動(dòng)語態(tài)與被動(dòng)語態(tài)的概念： 英語動(dòng)詞的語態(tài)有兩種：⑴主動(dòng)語態(tài)：表示主語是動(dòng)作的執(zhí)行者 ⑵被動(dòng)語態(tài)：表示主語是動(dòng)作的承受者(常常沒在有必要指出動(dòng)作的執(zhí)行者情況下使用) 例：They speak English. （主動(dòng)語態(tài)） 主 謂 賓 English is spoken by them. （被動(dòng)語態(tài)） 主 謂 介詞短語 注：☆及物動(dòng)詞有被動(dòng)語態(tài)，不及物動(dòng)詞必須帶有介詞才可以有被動(dòng)語態(tài)。 例：⑴We l

3、isten to the teacher carefully in class. 主 謂 賓 →The teacher is listened to by us carefully in class. 主　 謂　 介詞短語 ⑵Ｗe laughed at him . → He was laughed at by us. 二、 被動(dòng)語態(tài)的結(jié)構(gòu)與用法： ㈠結(jié)構(gòu)：be +done (過去分詞) 被動(dòng)語態(tài)中的be為助動(dòng)詞，無意義。be可能是am , is , are也可能是was ,were或

4、原形be。 　注：☆被動(dòng)語態(tài)的時(shí)態(tài)是由be的時(shí)態(tài)決定的，be是什么時(shí)態(tài)，全句就是什么時(shí)態(tài)，be后面的過去分詞不變。 ㈡用法： 　例：①Ｈistory is made by the people. (一般現(xiàn)在時(shí)) ②Ｔhe cars were made in Tianjing in 1995. (一般過去時(shí)) ③The tree will be cut down next year.(一般將來時(shí)) ④Ｔhe room must be kept clean.?。ê星閼B(tài)動(dòng)詞的被動(dòng)語態(tài)） ⑤The door is being opened

5、.?。ìF(xiàn)在進(jìn)行時(shí)） ⑥The film has been seen by me.?。ìF(xiàn)在完成時(shí)）　 三、 被動(dòng)語態(tài)的各種句型： １、 Ｔhe song is liked by young people. (肯定句) ２、 Ｔhe song isn’t liked by young people　?。ǚ穸ň洌? ３、 Is the song liked by young people ?　　?。ㄒ话阋蓡柧洌? ４、 Who is the song liked by ?=By whom is the song liked?　（特殊疑問句） 四、 主動(dòng)語態(tài)改被動(dòng)語態(tài)的方法：

6、方法分為三步：⑴把原句中的賓語改成主語 ⑵動(dòng)詞改為變動(dòng)形式be done(同時(shí)注意時(shí)態(tài)) ⑶原來的主語如果需要的話放在介詞by后面，以指明做的 人或物，如果沒有必要?jiǎng)t省去 例：The man killed a tiger. → A tiger was killed by the man .(改的過程中要注意時(shí)態(tài)和語態(tài)兩個(gè)方面) 五、 特殊句型的被動(dòng)語態(tài)： ⑴含有使役動(dòng)詞（make /let /have）或感官動(dòng)詞（hear ,see, listen to ,look at ,find ,watch, feel等）的句子，

7、在主動(dòng)語態(tài)中這些詞后常跟不帶to的動(dòng)詞不定式，但是在改成被動(dòng)語態(tài)時(shí)，則一定要把省去的to再加上去，另外help這一個(gè)詞在主動(dòng)語態(tài)中后面的動(dòng)詞不定式可以帶to,也可不帶to, 但在被動(dòng)語態(tài)中也必須把to加上去。 例：①M(fèi)other often makes me do some housework. →I am often made to do some housework by mother. ②We saw him run into the classroom. →He was seen to run into the classroom by us. ⑵te

8、ach ,give ,pass ,show ,buy, tell等動(dòng)詞常常帶有兩個(gè)賓語（雙賓語：直接賓語和間接賓語），改為被動(dòng)語態(tài)時(shí)，兩個(gè)賓語可以選其中任一個(gè)作主語。如果直接賓語被提前作主語，那么間接賓語（一般是人）前要加相應(yīng)的介詞to/for。 例：①Ｓhe gave me a pen.= She gave a pen to me. →I was given a pen by her. →A pen was given to me by her. ②My father bought me a new bike.= My father bought a new b

9、ike for me. →I was bought a new bike by my father. →A new bike was bought for me by my father. ⑶由不及物動(dòng)詞（vi）+介詞/副詞＋賓語的句子改成被動(dòng)語態(tài)時(shí)，介詞或副詞不能丟掉。(前面已舉過兩例) 　例：①Ｗe should speak to old people politely. →Old people should be spoken to politely ( by us). ②He took away the box..

10、 →The box was taken away by him. ⑷含有賓語補(bǔ)足語的句子改為變動(dòng)語態(tài)。（賓補(bǔ)放在原來位置不變） 　例：①We call him Xiao Ma. 主 謂　 賓 賓補(bǔ) 　　　→Ｈe is called Xiao Ma by us. ②He found the book very interesting. →The book was found very interesting by him. 六、 沒有被動(dòng)語態(tài)的動(dòng)詞： 　1. 沒有被動(dòng)語態(tài)的詞， 表示狀態(tài)或特征的及物

11、動(dòng)詞如 cost, fit, have, suit等沒有被動(dòng)形式，另外，諸如happen = take place, break out(爆發(fā))，break down(壞了) 等不及物動(dòng)詞或短語以及諸如result from(緣于)，belong to, consist of等只用主動(dòng)語態(tài)，而不用被動(dòng)語態(tài) ２不及物動(dòng)詞或動(dòng)詞短語無被動(dòng)語態(tài): appear,　die ,disappear, end (vi. 結(jié)束), fail, last, lie, remain, sit, spread（傳播）, stand, e true, fall asleep, ... ３.大多數(shù)系動(dòng)詞：be ,

12、feel (摸起來)，sound(聽起來)，look(看起來)， smell(聞起來) taste（嘗起來）等詞無被動(dòng)語態(tài)，它們的主動(dòng)形式表示被動(dòng)意義。 例：①Ｔhe skirt feels very soft. 這件裙子摸起來很柔軟。 　　②Many changes have happened in our hometown. ③The film lasted for 3 hours.
