之前练习的考察情
况进一步选择讲解
该语法项的重难点。 My mother felt alarmed when I had my hair coloured purple.
My mother was alarmed when I had my hair coloured purple.

Look at the sentences. Though the structure seems like a passive sentence, it is not. A passive sentence indicates a passive action while this sentence describes a situation when someone has the feeling of alarm. “alarmed” is an adjective formed by v+ed.Key!Discovering useful structures
Go over the passive voice
be + V+-ed/-en/-t
My hamburger was eaten by the
dog.
A new hospital will be built in our
city. 使用被动语态的情况1. 我们不知道或没有必要说明动作的执
行者是谁的时候(这时不带by引起的短语)。
Printing was introduced to Europe from
China. (省略了by短语。)
Look! There is nothing here. Everything
has been taken away. (省略了by短语。)2. 当我们出于礼貌、措辞委婉等方面的
考虑不愿说出动作的执行者是谁时。
You are requested to give a performance.
You are cordially (诚挚地) invited to a
party to be given at the Teachers' Club
at 3 p.m. Nov. 23.
3. 当我们强调或兴趣在动作的承受者
时(这时可带by引起的短语)。
The song was composed by a student.
A good time was had by all.被动语态由be+过去分词构成，be随时
态的变化而变化。以give为例，各种时
态的被动语态形式为：
一般现在时：am/is/are + given
【例句】
The first section of New College
English is designed for speaking practice
and is based on pictures and topics.
　　被动语态的构成一般过去时：was/were + given
【例句】
These computers were made in our own country.
一般将来时：will/shall be + given
【例句】
Shall we be asked to attend the opening ceremony?
　过去将来时：would be + given
【例句】
The news would be sent to the
soldier's mother as soon as it arrived.现在进行时：am/is/are being + given　
【例句】
Trees are being planted over there by
them.
过去进行时：was/were being + given
【例句】
The feast was being prepared when the birds arrived in the sky.
现在完成时：have/has been + given
【例句】
Swift progress has also been made in culture and education.过去完成时：had been + given
【例句】
The huge bridge had been damaged
before the World War II.
　　
将来完成时：will/shall have been + given
【例句】
The book will have been published by the end of next month.含有情态动词的动词变成被动语态：情态动词 + be + 过去分词This problem can be solved.
这问题可解决。
What’s done cannot be undone.
覆水难收。1. 有些动词可以有两个宾语，在用于被动结构时，可以把主动结构中的一个宾语变为主语，另一宾语仍然保留在谓语后面。通常变为主语的是间接宾语(指人的宾语）。一些特殊的被动语态They didn’t offer Ann the job. Ann wasn’t offered the job.
安未得到这份工作。2. 在使役动词have, make, get以及感官动词see, watch, notice, hear, feel, observe等后面不定式作宾语补语时，在主动结构中不定式to要省略，但变为被动结构时，要加 to。They make her clean the floor. ?She is made to clean the floor by them.3. It + be + 过去分词 + that从句 (=主语+ be + 过去分词 + to do sth.)表示：据说/据报道/据悉/据信等……据说这个男孩已经通过了这次全国性的测试。It is said that the boy has passed the
national exam.
The boy is said to have passed the
national exam.4. be supposed to
suppose vt. 推想; 假设; 猜想
supposed adj. 假定的; 推测的; 意图的
(1) 据说 (=be said to)
Let’s go and see that film. It’s supposed
to be very good.
我们一起去看那电影好吗? 人们都说它
不错。(2) 计划、安排I’d better hurry. It’s nearly 8 o’clock. I’m supposed to be meeting Tom at 8:15.我要快些了。现在差不多8点钟了。
我8点一刻去接汤姆。(3) be not supposed to 不允许
You are not supposed to park here.
这儿不允许停车。动词get代替be。(get往往用在口语
中。)酒馆里发生了打斗，幸好无人受伤。There was a fight at the pub, but fortunately nobody got (=was) hurt.get + done 同 be + done 的区别：get done 往往表示行为不是计划之中，而是意外发生的。The dog got run over by a car.
狗被汽车辗死了。1. 某些感官动词加形容词及少数其他的动词可以表示被动意义。
cook, smell, taste, wash, write, shut,
prove, sell, read, write
1. The dish tastes delicious.
2. The theory proved right at last.
3. The book is so interesting that it
sells well. 不可以变成被动语态The book is so interesting that it sells well.
“sells”此处为不及物动词“销售起来; 有销
路”的意思；作及物动词为“卖; 出售”
This kind of cloth washes well. (耐洗) need + V- ing 表示“主语承受动词
发出的动作”，表示被动意义。
我的车需要修理。
My car needs repairing
(= to be repaired). beg, equal, fail, hold, possess, fit，
become, contain, cost, have, lack, resemble (相似), suit等。This new English-Chinese dictionary
cost me ten dollars.3. 某些表示状态或者特征的及物动词
没有被动语态形式。这类动词常见的有：战争爆发了。
可以说：The war broke out.
但不能说：The war was broke out.4. 通常只有及物动词（组）才有被动语态，不及物动词没有。 “be + 过去分词”这个结构并不都是被动语态，也可能是系表结构。被动语态与系表结构主要区别是：被动结构表示一个动作，而系表结构表示主语的特点或所处的状态，试比较下面的句子：被动结构与系表结构的区别被动结构
The enemy was soon surrounded by us.
系表结构
The house is surrounded by trees.
被动结构
She was bitten by the dog in the darkness.
系表结构
I was excited by the news that my husband
got promoted.Review在英语中的被动语态使用得比汉语要多，一般说来，当强调动作承受者，不必说出执行者或含糊不清的执行者时，多用被动语态。
被动语态强调动作，系表结构强调状态。Individual activity注: 另附 word 文档。
