1、学习必备欢迎下载一、被动语态的构成形式1. 被动语态的基本时态变化被动语态通常为十种时态的被动形式, 被动语态由 be 过去分词构成， be 随时态的变化而变化。以do 为例，各种时态的被动语态形式为： 1) am/is/are +done (过去分词 ) 一般现在时例： Visitors are requested not to touch the exhibits. 2） has /have been done 现在完成时例： All the preparations for the task have been completed, and were ready to start. 3）
2、 am/is /are being done 现在进行时例： A new cinema is being built here4） was/were done 一般过去时例： I was given ten minutes to decide whether I should reject the offer. 5） had been done 过去完成时例： By the end of last year, another new gymnasium had been completed in Beijing. 6） was/were being done 过去进行时例： A meeting
3、 was being held when I was there. 7） shall/will be done/ be going to be done/ be about to be done/ be to be to done一般将来时例： Hundreds of jobs will be lost if the factory closes. 8） should/would be done; was/ were going to be done; was/ were about to be done; was/ were to be to done一般将来时例： The news wou
4、ld be sent to the soldiers mother as soon as it arrived. 9） shall/will have been done 将来完成时（少用）例： The project will have been completed before July. 10） should/would have been done 过去将来完成时（少用）例： He told me that his new clothes would have been made very soon. 2. 被动语态的特殊结构形式1)带情态动词的被动结构。其形式为：情态动词be 过去分
5、词。例： The baby should be taken good care of by the baby-sitter. 2) 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. 例： His mother gave him a present for his birthday. 可改为He was given a present by his mother for his birthday.3) 当“ 动词+ 宾语+ 宾语补足语 ” 结构变为被动语态时，将宾语变为被动结构中的主语，其余不动。例： Someo
6、ne caught the boy smoking a cigarette. 可改为The boy was caught smoking a cigarette.4） 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，但为为被动结构时，要加to 。例： Someone saw a stranger walk into the building. 可改为A stranger was seen to walk into the building.精选学习资料

8、 that+从句及其他类似句型一些表示“ 据说” 或“ 相信” 的动词如 believe, consider, expect, report, say, suppose, think等可以用于句型 “ It be 过去分词 that 从句” 或“ 主语 be过去分词 to do sth.”。有： It is said that 据说,It is reported that据报道，It is believed that大家相信，It is hoped that 大家希望，It is well known that 众所周知， It is thought that大家认为， It is sugge
9、sted that 据建议。例： It is said that the boy has passed the national exam. （The boy is said to have passed the national exam. ）三、谓语动词的主动形式表示被动意义1.英语中有很多动词如break ，catch ，clean ，drive ，lock ，open ，sell ，read ，write ，wash 等，当它们被用作不及物动词来描述主语特征时，常用其主动形式表达被动意义 ,主语通常是物。例： This kind of cloth washes well. 注意：主动语
10、态表被动强调的是主语的特征，而被动语态则强调外界作用造成的影响。试比较：The door wont lock （指门本身有毛病）The door wont be locked （指不会有人来锁门 , 指“ 门没有锁 ” 是人的原因）2. 表示“ 发生、进行” 的不及物动词和短语， 如： happen, last, take place, break out, come out, come about, come true, run out, give out, turn out 等以主动形式表示被动意义。例： How do the newspapers come out? 这些报纸是如何引出来
11、的呢？3. 系动词没有被动形式 , 但有些表示感受、感官的连系动词feel, sound, taste, book, feel等在主系表结构中常以主动形式表示被动意义。例： Your reason sounds reasonable. 四、非谓语动词的主动形式表被动意义在某些句型中可用动名词和不定式的主动形式表被动意义。1 在 need ，want ，require, bear等词的后面，动名词用主动形式表示被动意义，其含义相当于动词不定式的被动形式。例： The house needs repairing（to be repaired）这房子需要修理。2 形容词 worth后面跟动名词的主动
12、形式表示被动含义，但不能跟动词不定式；而 worthy后面跟动词不定式的被动形式。例：The picture-book is well worth reading（The picture-book is very worthy to be read）3. 动词不定式在名词后面作定语，不定式和名词之间有动宾关系时，又和句中另一名词或代词构成主谓关系, 不定式的主动形式表示被动含义。例： I have a lot of things to do this afternoon (to do与 things是动宾精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -
13、第 2 页，共 7 页学习必备欢迎下载关系，与 I 是主谓关系。 )试比较：I ll go to the post office. Do you have a letter to be posted? ( 此处用不定式的被动语态作定语表明you 不是 post 动作的执行者。 )4. 在某些 “ 形容词不定式 ” 做表语或宾语补足语的结构中，句子的主语或宾语又是动词不定式的逻辑宾语时，这时常用不定式的主动形式表达被动意义。这些形容词有 nice ，easy ，fit ，hard ，difficult，important，impossible，pleasant ，interesting等。例：
14、This problem is difficult to work out .（可看作 to work out省略了 for me ）.5在 too to 结构中，不定式前面可加逻辑主语，所以应用主动形式表示被动意义。例： This book is too expensive (for me) to buy. 6. 在 there be 句型中，当动词不定式修饰名词作定语时，不定式用主动式作定语，重点在人，用被动形式作定语，重点在物。例： There is no time to lose（to be lost）（用 to lose可看成 for us to lose ；用 to be lost
15、，谁 lost time不明确。）7. 在 be to do结构中的一些不定式通常应用主动表主动, 被动表被动。 然而,由于古英语的影响 ,下列动词 rent,blame,let等仍用不定式的主动形式表示被动意义。例： Who is to blame for starting the fire? 五、介词in, on, under等+ 名词构成介词短语表被动意义表示方位的介词与含动作意义的名词合用，含被动之义，其意义相当于该名词相应动词的被动形式，名词前一般不用冠词。1. “under +名词” 结构，表示 “ 某事在进行中 ” 。常见的有： under control（受控制）, under
16、 treatment（在治疗中）, under repair（在修理中）, under discussion（在讨论中） , under construction（在施工中）。例： The building is under construction( is being constructed). 2“beyond+ 名词” 结构， “ 出乎 胜过 、范围、限度 ” 。常见的有：beyond belief (令人难以置信 )， beyond one s reach （鞭长莫及） ，beyond one s control（无法控制）， beyond our hope 我们的成功始料不及。例：
17、The rumor is beyond belief（=cant be believed）3. “above+名词 ” 结构, 表示“( 品质、行为、能力等 ) 超过 、高于”。例： His honest character is above all praise=His honest character cannot be praised enough4“for+名词” 结构，表示 “ 适于 、 为着” 。如：for sale(出售), for rent （出租）等。例： That house is for sale. (= That house is to be sold). 5“in+名
18、词” 结构 ，表示“ 在 过程中或范围内 ” 常见的有： in print （在印刷中）， in sight(在视野范围内 ) ，等。例： The book is not yet in print(=is not yet printed)6“on+名词” 结构, 表示“ 在从事 中” 。常见的有：on sale( 出售)，on show （展出） , on trial（受审）。例： Today some treasures are on show in the museum (= are being showed). 7 “out of+ 名词” 结构 ； 表示 “ 超出 之外“ ， 常见的有
19、：out of control 精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 3 页，共 7 页学习必备欢迎下载(控制不了 )， out of sight （超出视线之外） ， out of one s reach(够不着 ), out of fashion(不流行 ) 等。例： The plane was out of control (can t be controlled) 。8“within+ 名词” 结构， “ 在 内、不超过 ”。例： He took two days off within the teachers permissio
20、n六、被动语态与系表结构的区别当“be+过去分词 ” 作被动语态时表示主语承受的动作； 作系表结构时表示主语的特点或所处的状态时，be 后面的过去分词是表语，相当于形容词。其区分办法如下：1如果强调动作或句中有介词by 引导出动作的执行者，该句一般为被动语态，否则为系表结构。例： The glass is broken （系表结构）The glass was broken by the boy （被动语态）2如果句中有地点、频率或时间状语时，一般为被动语态。例： The door is locked （系表结构）The door has already/just been locked（被动语
21、态）3被动语态除用于一般时态和完成时态外，还可以用于其他各种时态，而系表结构中的系动词be 只有一般时态和完成时态。例： The machine is being repaired七、被动语态与高考试题赏析1高考对谓语动词语态的考查例析1). In some parts of the world, tea _ with milk and sugar. (NMET1993)A. is servingB. is served C. Serves D. served 解析： B 因为serve 是及物动词，其动作承受者tea 作主语，表示经常发生的情况，故用一般现在时的被动语态。2). This i
22、s Teds phone. We miss him a lot. He _ trying to save a child in the earthquake.(NMET2002)A. killed B. is killed C. was killed D. was killing 解析： C Ted是 kill 的承受者，用被动语态，且Ted 救人发生在过去，所以用一般过去时的被动语态。3). - Have you moved into the new house?- Not yet, the rooms _. (NMET1991) A. are being painted B. are pa
23、inting C. are paintedD. are being painting 解析： A “house”和“paint ”应该是被动的关系，排除B，D。后者未搬进新居的原因是房子正在油漆， 所以要用现在进行时的被动语态。不能用一般现在时表示习惯性动作，排除C。4). When and where to go for the on-salary holiday _ yet. （上海春 2003 ）A. are not decided B. have not been decided C. is not being decided D. has not been decided 解析： D
24、 decide是及物动词，动作的发出者通常是人，句中的主语是动作的承受者，所以 decide要用被动语态。从题干的语境和关键词yet ，可判断用现精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 4 页，共 7 页学习必备欢迎下载在完成时，不定式做主语用单数，故用现在完成时的被动语态。5). The manager entered the office and was happy to learn that four-fifths of the tickets _.（上海春 2001 ）A. was booked B. had been booked
25、 C. were booked D. have been booked 解析： B 句中 tickets是 book( 订票)的承受者，主谓为被动关系，又因票已被订出应发生在entered the office这个过去动作之前，所以要用过去完成时的被动语态。2高考对非谓语动词语态的考查当非谓语动词的逻辑主语为动作的承受者时, 须用被动式。弄清非谓语动词与其逻辑主语之间的执行与承受关系是掌握非谓语动词语态的关键。1). Having a trip abroad is certainly good for the old couple, but it remains _ whether they
26、will enjoy it. (NMET2002)A. to seeB. to be seen C. seeing D. seen 解析： B 根据题意，那对老夫妇是否到国外旅行是将来的动作，应使用不定式，故排除掉 C、D 两项；又因 remains的逻辑主语 it 是动词 see 说表示动作的承受者，即 “ 到国外旅行 ” 这件事，这件事有待于 “ 被决定 ” ，应使用动词不定式的被动形式。2). While shopping, people sometimes cant help _ into buying something they don t really need. （上海 199
27、6 ）A. to persuaded B. persuading C. being persuaded D. be persuaded 解析： C cant help doing “禁不住做某事 ” ，排除 A 和 D；顾客应是 “ 被劝说 ”购物的，要用动名词的被动语态。3）. I feel it is your husband who _ for the spoiled child. （上海 2002 ）A. is to blame B. is going to blame C. is to be blamedD. should blame 解析：A feel的宾语从句为强调句型，在be
28、to do结构中，在某些场合可用不定式的主动语态表示被动语态，如to blame，to let等。强调句型讲解“ 强调 ” 就是使句子的某一部分比一般情况下显得更加重要。英语表达中， 要强调句子的某一成分， 一般可用强调句型“It is (was) +that (who) +句子的其余部分” 。It 在句中无意义，只起引出被强调部分的作用。被强调的部分指人时，除可用that外，还可换用who （强调宾语指人时也可用whom ）。使用强调句型时，应注意以下事项：一、去掉强调结构It is (was) that(who)后，剩下的词仍能组成一个完整的句子。这是判断是不是强调句型的关键。试比较：1.
29、 It is strange that he didn t come yesterday.2. It is you and Tom that didn t come yesterday.显然，句 1 去掉 It is that 后， 句子结构不完整， 是主语从句； 句 2 去掉 It is that 后，句子变为you and Tom didn t come yesterday. 仍是一个表意完整的句子，这是一个强调句。再如：精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 5 页，共 7 页学习必备欢迎下载1. It is what you do
30、rather than what you say _matters. （ 05 天津） A.that B. what C.which D. this 答案 A。这是一个强调主语的强调句型，去掉强调结构， 剩下的是What you do rather than what you say matters. 表意完整。2. That was really as plan did evening. It s years _I enjoyed myself so much. A.when B. that C.before D.since （05 安徽）答案 D。由强调句型的判断方法可知，该句不是强调句型
31、。It 指时间，句意为：好几年我没有这么高兴了。since 的意思是 “ 自从那个时候起” 。二、如果强调时间、地点、原因或方式状语时，不可用when, where, why或 how ，而仍用 that 。试比较： It was because of the accident why he was late. (误), It was because of the accident that he was late. (正) 。再如：1. It was not until midnight they reached the camp site. （08 重庆）A. that B.when C.
32、while D. as 答案 A。该题强干扰项是B，考生容易因强调时间状语until midnight而误选。2. It was after he got what he had desired _he realized it was not so important. （06 辽宁） A.that B.when C.since D. as 答案 A。该句强调时间状语从句after he got what he had desired，题干意思是“ 得到他所梦寐以求的东西后他才意识到一切都不那么重要” 。不要误选B。3. It was in New Zea land _ Elizabeth f
33、irst met Mr. Smith. （08 全国 II ）A. that B.how C.which D. when 答案 A。强调地点状语in New Zea land. 三、注意强调句型的否定句和疑问句形式，在这方面很容易因弄不清句子结构而错选。如: 1. I just wonder _that makes him so excited. （06 山东）A. why it does B. what he does C. how it is D. what it is 答案 D。正常语序的强调句型容易看出，但要注意它的变体。如果把该题变换一下语序：it is what that make
34、s him so excited,不难看出这是强调句型的特殊疑问句形式，强调了疑问代词what ，因为 wonder后宾语从句，故用了陈述语序。2. It was not until she got home _Jennifer realized she had lost her keys. A. when B. that C.where D.before （06 全国卷二）答案 B。 如果去掉强调结构，该句是一个 “ not until”句型：Jennifer didn t realize she had lost her keys until she got home. 要强调时间状语un
35、til she got home，这时要把主句中的否定词not 放在 was 之后。四、强调主语时，that 或 who后面的谓语动词的形式仍然取决于原句中的主语；be 的变化只有is 和 was 两种形式，如果要表示现在时将来时的其它各种形式时，就用 It is, 表达过去时的各种形式时，用It was . 一般要与谓语动词的时态一致。如：1. It is I who/ that am an English teacher. 2. It is the boy who/ that speaks English best in the class. 3. It was on Sunday tha
36、t he gave George this ticket. 4. It is the little girl who/ that has broken the glass. 五、在复习中有可能把It is/ was that句式都误认为是强调句型的几种情况：1、把具有实际意义的指示代词it 后面接 is/was that误认为是强调句式。精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 6 页，共 7 页学习必备欢迎下载- Where did you get to know her? （ 07 山东）- It was on the farm _ we
37、 worked. Athat Bthere Cwhich D where 答案 D。该句易误作强调句型，所以A 是强干扰项。这里where we worked 是定语从句，修饰 the farm。It 指 “ 与她相识 ” 这件事。该题很容易受思维定势的影响而拒绝选D，因为平日教学老师一再强调，用强调句型时即使强调地点状语，也不能用 where而用 that 。该句如果要用it was that强调句型的话，可改写为“It was on the farm where we worked that I got to know her.”2、把 it 指时间、天气、距离、环境等后接be 的情形误以
38、为是强调句型。It was twenty miles from our city to the village _the accident happened. A. that B.when C. then D.where 答案 D。本题貌似It was that强调句型，其实不然。句中It 表示距离， where 引导地点状语从句。3、把 It is/ was that结构的主语从句误认为是强调句型。The Foreign Minister said, “ _our hope that the two sides will work towards peace.” （04 北京）A. This
39、 is B. There is C. That is D. It is 答案 D。如果选 A 和 C，指示代词This 和 That 在句中找不出指代的内容，选B 意义不通。故选 D 。虽然选It is后题干中出现了It is that 结构，但这不是强调句型。很明显，题干中的 that从句应是主语从句，所缺的是形式主语。4、_ is our belief that improvements in health care will lead to a stronger, more prosperous economy A. As B. That C. This D.It （06 浙江）答案 D
40、。如果去掉It is that, 中间的 our belief就无法处理，因此该句不是强调句型，而是一个复合句，It 是形式主语， that引导真正主语。强调句型It is/ was that/ who主要用来强调句子的主语、宾语、状语或表语。如果要强调谓语动词,应该用代动词do 及其变形 does 或 did ， 这三种形式常用在谓语动词之前，以加强语气。它一般只能强调现在时与过去时。如：I do wish I could. 我真希望我能。He does look well. 他的确看起来气色很好。You did give me a fright. 你真把我给吓了一跳。精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 7 页，共 7 页
