15、的宾语补足语就是被动态句子中的主语补足语。先了解宾语补足语，则很容易了解主语补足语。宾语补足语: 在英语中，某些及物动词不仅需要宾语，而且还要求某个词或词组来补充说明宾语，即表示宾语代表的人或物所发出的动作或所处的状态，这个词或短语称为宾语补足语。有些语法书把宾语和补足语称为复合宾语。句型：及物动词+宾语（n./pron.）+ 宾语补足语（n./ adj./ adv./ to do/ -ing/ -ed/ 介词短语7种表示法）该句型若变成被动语态，即将宾语提到句首作主语，原主动语态中的宾语补足语此时在被动语态中起到补充说明主语的作用，所以改称主语补足语。例如：A cook will be im
16、mediately fired if he is found smoking in the kitchen. （03全国卷）此句中smoking 是主语 he的补足语，所以称为主语补足语。A cook will be immediately fired if someone finds him smoking in the kitchen.此句中smoking 是宾语 him的补足语，所以称为宾语补足语。二、何时用现在分词、何时用过去分词作主语（宾语）补足语分词作主语（宾语）补足语时，若主语（宾语）与分词之间是主动关系，则用现在分词表示主动；如果主语（宾语）与分词之间是被动关系，则用过去分词表
17、示被动。例如：He was heard singing in the next room. He was singing. 主语he与补足语“唱歌”之间是主动关系, 故用现在分词singing。One of the glasses was found broken. One of the glasses was broken. 主语 one of the glasses与补足语“打破”之间是被动关系, 故用过去分词broken。Dont leave the water running while you brush your teeth. （04天津）The water is running.
18、 宾语the water与补足语“淌”之间是主动关系，故用现在分词running。 三、可以用分词作主语或宾语补足语的动词 要会使用分词作补足语，必须记住哪些动词可以接分词充当补足语。1. 感官动词 feel, hear, listen to, see, watch, notice, observe, look at (一感二听五看) 及find 等既可以接现在分词又可以接过去分词充当补足语。如： If you wave your book in front of your face, you can feel the air moving against your face. The air
19、 can be felt moving against your face, if you wave your book in front of your face.The next morning she found the man lying in bed, dead. The next morning the man was found lying in bed, dead.2表示 致使 动词 get, have，leave等既可以接现在分词又可以接过去分词充当补足语。-Good morning. Can I help you? -Id like to have the package
20、weighed, madam. （MET89）3. 表示“意欲；命令”的动词如 like, want, wish, order等常接过去分词充当补足语。 如： You must tell us exactly what you would like done. 你必须准确地告诉我们该做什么。The father wants his daughter taught the piano. 这位父亲想让女儿学钢琴。I wish it done quickly. 我希望很快将此事做完。注意： set, start, catch常跟现在分词作宾语补足语，make常跟过去分词作宾语补足语。如：set sb
21、 thinking start sb coughingHe looked around and caught a man putting his hand into the pocket of a passenger.（04北京春季）The speaker raised his voice but still couldnt make himself heard. （NMET91）典例精析：1. 1 smell something _ in the kitchen. Can I call you back in a minute? （2007全国I）A. burning B. burnt C.
22、 being burnt D. to be burnt答案：A。解析：smell something burning“闻着什么东西在燃烧而发出糊味”强调这个动作正在进行。burning 作宾语补足语。something burnt “烧焦了的东西”表示一种状态。所以选A。2. After a knock at the door, the child heard his mothers voice _ him. (2007上海) A. calling B. called C. being called D. to call答案：A。解析：hear sb. doing sth. 意为“听到某人在做
23、某事”。动词+ing表示主动，the child heard his mothers voice calling him表示“孩子听见他母亲喊他”。hear sth. done 表示“听见某事被做了”。所以选A。3. Jenny hopes that Mr. Smith will suggest a good way to have her written English_ in a short period. （2007福建）A. improved B. improving C. to improve D. improve答案：A。解析：have sth. done 表示“使某事被做”，ha
24、ve her written English improved“使她的书面英语得到提高”。动词+ed形式作宾语补足语表示被动。have sb. doing sth. 意为“使某人一直在做某事”表主动。have sb. do sth. 意为“使某人做某事”表主动，do前必须省略to。所以选A。4. - Did Peter fix the computer himself?- He _, because he doesnt know much about computers. (2007安徽) A. has it fixed B. had fixed it C. had it fixed D. f
25、ixed it答案：C。解析：have sth. done 表示“使某事被做或请别人做某事”，动词+ed形式作宾语补足语表示被动。由because he doesnt know much about computers可判断出，他找别人维修了电脑。所以选C。分词作状语难点形成原因:1. 对在句中作时间、条件、原因还是别的状语不是很清楚。2分不清何时用现在分词、何时用过去分词。解决办法：1理解分词作状语时可以转换成相应的状语从句。2分清何时用现在分词、何时用过去分词。用法讲解：1. 分词或分词短语作状语时，可以表示时间、原因、让步、条件，方式或伴随状况。通常可转换成相应的状语从句；表示方式或伴随
26、状况时可以转换成并列句或非限制性定语从句。例如：Put into use in April 2000 (=When it was put into use in April 2000), the hotline was meant for residents reporting water and heating supply breakdowns. (2005上海) 分词短语作时间状语Blamed for the breakdown of the school computer network (=Because she was blamed for the breakdown of the
27、 school computer network), Alice was in low spirits. (2006福建) 分词短语作原因状语Given time (=If he is given time), hell make a fist-class tennis player. （03北京）分词短语作条件状语We often provide our children with toys, footballs or basketballs, thinking that all children like these things. (= and think that all childr
28、en like these things.) (2006全国3) 分词短语作伴随状语2. 有时为了强调，分词前可带when, while, if, though, as if, unless等连词一起作状语，以便使句子的意思更清楚、更连贯。例如：When comparing different cultures, we often pay attention only to the differences without noticing the many similarities. （2006浙江）Though tired, he still continued reading.3. 现在分
29、词和过去分词作状语时的用法比较。 不管是现在分词还是过去分词单独作状语，其逻辑主语必须与主句的主语一致。分词作状语通常可转换成一个相应的状语从句或并列句，如果状语分句或并列句中的谓语动词为被动结构，就用过去分词；如果状语分句或并列句中的谓语动词为主动结构，就用现在分词。例如：When compared with the size of the whole earth , the biggest ocean does not seem big at all. （04湖北）分词部分相当于When the biggest ocean is compared with the size of the
30、whole earth, 主语与分词是被动关系，所以用过去分词。When comparing it with the size of the whole earth, we find that the biggest ocean does not seem big at all.When we compare it with the size of the whole earth. 主语与分词是主动关系, 所以用现在分词。Faced with a bill for10,000(=Because he is faced with a bill for10,000), John has taken
31、 an extra job. (2006全国2)Whenever he was asked why he was late for class, he would answer carelessly, always saying the same thing (= and he would say the same thing). （2006江苏）注意：1. 现在分词有两种时态：一般式doing和完成式having done。一般式通常表示与主句的谓语动词所表示的动作同时发生或无先后；完成式则强调分词所表示的动作先于谓语动词所表示的动作。 如：While walking in the stre
32、et, we met some friends of ours.（同时发生）Having waited in the queue for half an hour, Tom suddenly realized that he had left his wallet at home. （04北京） （“等待”先于谓语动词“意识到”） 2. 分词的否定式的构成: not +分词。 Not having received a reply, he decided to write again.难点形成原因：. 分不清什么是独立主格结构。. 分不清何时用现在分词、何时用过去分词。. 遇到时容易和其他知识
33、点混杂。. 练得不多、用得不熟。解决办法：. 要先下功夫学会分词作状语现象，然后再引申出分词与句子主语既无主动又无被动关系现象，从而导出分词的独立主格结构。. 典型例句进行精讲精炼。用法讲解： 独立主格结构与主语之间没有句法上的联系，但是与句子的意义是紧密联系在一起的。它只能属于短语，而不可以单独成为一个句子，是一个独立于句子之外，但是又能表达一个句子意思的独特的结构。它的位置比较灵活，可以置于句首、句中、句尾，通常与句子之间用逗号隔开。 其结构是：名词/代词+动词不定式/现在分词/过去分词/形容词/副词/介词短语/名词，起到逻辑主语作用的代词要用主格形式，不可以用宾格。“with+复合宾语”
34、实际上也是独立主格结构的一种，但是此结构中的代词用宾格形式，即“with+宾语+宾语补足语”。 独立主格结构在句中主要用来作状语，可以表示原因、方式、时间、伴随等，with+复合宾语结构除了可以作状语外，还可以用来作定语。以下分六种情况分别介绍：1. 名词/代词+动词不定式 表示动作发生在主句动词动作之后或者还没有发生，构成形式是：n/ pron.+ to do sth., 如果不定式与其逻辑主语之间是动宾关系，就用动词不定式的被动形式。如：The examination to be held tomorrow morning, I couldnt go to surf the Interne
35、t tonight.明早就要考试了，今晚我不能上网了。2. 名词/代词+现在分词 表示动作与主句动词动作同时发生，构成形式是：n/ pron.+ doing,如果强调分词的事件发生在主句动作时间之前，通常用现在分词完成式形式来表示。如：It being a fine day, we decided to go swimming.因为天气不错，我们决定去游泳。（表示原因）The students having done all the exercises, the teacher went on to explain the text.学生做完所有练习之后，老师继续讲解课文。（表示时间）3. 名
36、词/代词+过去分词 如果所用的分词与主格名词或代词之间是动宾关系，由于独立主格中的名词或代词就是短语的逻辑主语，因此要用过去分词，表示过去分词与逻辑主语之间的被动关系。如：The prisoner stood there, his hands raised.（表示伴随状况）4. 名词/代词+非动词（名词、形容词、副词、介词短语）该结构主要用来表示对句子的细节进行补充说明，主要是用来表示方式、伴随、原因、时间等。如：I heard that she got injured in the accident, my heart full of worry.我听说她在这场事故中受伤了，心中充满担忧。（
37、形容词，表伴随）We went many guests, most of them Americans.我们会见了许多客人，他们当中大部分是美国人。（名词，表补充说明）The murderer got into the house, a sword in his hand.凶手闯进房间，手里拿着一把剑。（介词短语，表伴随）提示：在跟介词短语时，要考虑到介词两边的名词的对等关系，即如果是“名词+介词+名词”结构，当两边的名词都是可数名词单数形式时要注意：要么两边的名词都用限定词，要么都不用限定词，例如：The murderer got into the house, a sword in his
38、 hand.=The murderer got into the house, sword in hand. =The murderer got into the house , with a sword in his hand. 5. with+宾语+宾语补足语“with+名词（代词）+现在分词”表正在进行 I couldnt do my homework with all that noise going on. (05北京)“with+名词（代词）+过去分词”表被动It was a pity that the great writer died with his works unfini
39、shed.( NMET2004福建)“with+名词（代词）+动词不定式”表将来 I send you 100 dollars today, the rest to follow in a year. （05湖南）With all this work to do, I dont know if Ill have time to go out. 有这么多工作要做，我不知道是否有时间出去。“with+名词（代词）+形容词/副词/名词/介词短语”表宾语的性质或状态She used to sleep with the windows open. With Mr Smith away, weve got
40、 more room. With production up by 60%, the company has had another excellent year.(NMET2000) He left home, with his wife a hopeless soul. 他走了，妻子十分伤心。6. there be 句型的独立主格结构there be句型比较特殊，虽然它是一个倒装句，主语是be动词之后的名词形式，但是在独立主格结构中there却占据主格的位置，即there being., 如：There being no bus, we had to go back home on foo
41、t.因为没有公共汽车，我们不得不步行回家。There being no one in the classroom, Mr. Wang wondered what was happening.教室里一个同学都没有，王老师不知道发生了什么事。典例精析：1.The country has already sent up three unmanned spacecraft, the most recent _ at the end of last March. （2007山东）A. has been launched B. having been launchedC. being launched D
42、. to be launched答案：B。解析：根据题干中提供的时间判断，最近的spacecraft已经被发射，所以选择B。 being launched表示“正在被发射”； to be launched表示“将要被发射”。 若选has been launched，则成了两句话There being 的用法难点形成原因：1. 不清楚此概念。2. 搞不懂何时使用。3. 没有经常总结归纳。解决办法：记住何种情况下使用there being。用法讲解：there be句式的非谓语形式There be 的非谓语形式有两种，即there to be 和there being。需要掌握以下几个情况： 1.
43、 作主语 当作主语时，一般是There being结构，当句式中有for时，一般用there to be。如： There being a shop here is a great advantage. 这儿有个商店，真是方便极了。 It is impossible for there to be any more. 不可能再有了。 2. 作宾语 作动词宾语时，一般用there to be 结构。常见动词有：expect, mean, intend want, prefer等： We expect there to be no argument. 我们希望不会出现争吵。 People dont
44、 want there to be another war. 人们不希望再有战争。 作介词的宾语一般用There being句式，但当在for后时一般用there to be句式。 This depended on there being a sudden change. 这需要有一个突然的改变。 The teacher was waiting for there to be complete silence.老师在等着大家都安静下来。 3. 作状语 用作状语的there be的形式通常用there being结构。 There being no buses, we had to walk h
45、ome. 由于没有公共汽车，我们不得不走着回家。 There being no nobody in the room, we realized that there was no use crying. 屋里没人，我们意识到哭喊是没有用的。 注意：如果句中出现for时应用there to be。 It was too late for there to be any buses. 太晚了，没有公共汽车了。 典例精析：1. Owing to _no shipping space up to the moment, we have to require delayed shipment. A. t
46、here is B. there be C. there was D. there being答案：D。解析：owing to 后面应该加名词, 作介词的宾语一般用there being句式，故选D。2. _ nothing else to do, we went home happily. A. There to be B. There be C. There was D. There being答案：D。解析：本题句意为：由于没事可做，我们快乐地回家了。所选部分应该在句中作状语。用作状语的there be的形式通常用there being结构。故选D。3.Idontwant_anymisu
47、nderstandingbetweenus.A. there to be B. there be C. there is D. there being答案：A。解析: 本题句意为：我不希望我们之间有什么误会。所选部分在句中作动词的复合宾语。作动词宾语时，一般用there to be 结构，故选A。4. _ a house with a garden is of great value. A. There to be B. There be C. There was D. There being答案：D。解析: 本题句意为：拥有花园的房子是很有价值的。 所选部分应该在句中作主语,当作主语时，一般
48、是there being结构, 故选D。过去完成进行时与将来完成时难点形成原因：1.不清楚用法。2.未注意与它搭配的时间状语。解决办法：1彻底理解过去完成进行时与将来完成时基本用法。2注意与它搭配的时间状语。用法讲解：一、 过去完成进行时（一）构成：过去完成进行时是由had been +现在分词构成。She had been suffering from a bad cold when she took the exam. 她在考试之前一直患重感Had they been expecting the news for some time? 他们期待这个消息有一段时间了吧？（二）用法:1. 表示
49、过去某一时间之前一直进行的动作。 过去完成进行时表示动作在过去某一时间之前开始，一直延续到这一过去时间。和过去完成时一样，过去完成进行时也必须以一过去时间为前提。过去完成进行时也是一个相对的时态, 上下文中须有明示或暗示的作为参照的过去的时间。I had been looking for it for days before I found it. 这东西我找了好多天才找着。They had only been waiting for the bus a few minutes when it came. 他们只等了几分钟车就来了。2. 表示反复的动作。He had been mentioni
50、ng your name to me. 他过去多次向我提到过你的名字。 3. 过去完成进行时还常用于间接引语中。The doctor asked what he had been eating. 医生问他吃了什么。I asked where they had been staying all those days. 我问他们那些天呆在哪儿。 4. 过去完成进行时之后也可接具有突然之意的when分句。I had only been reading a few minutes when he came in. 我刚看了几分钟他就进来了。Shed only been reviewing her le
51、ssons for a short while when her little sister interrupted her.她温习功课才一会儿，她妹妹就打断她了。（三）过去完成进行时和过去完成时的比较:She had cleaned the office, so it was very tidy.她已经打扫过办公室了，所以很整洁。 (强调结果)She had been cleaning the office, so we had to wait outside.她一直在打扫办公室，所以我们不得不在外面等着。 (强调动作一直在进行)二、将来完成时（一）构成：will/shall have +过
52、去分词 We hope it will have stopped raining before we set off for the picnic. 我们希望在出发去野餐以前雨就已经停了。Ill have done all the work by the time you are back this evening. 你们今晚回来的时候我就将做完所有的工作了。（二）用法：1. 表示在将来某一时刻将完成或在另一个未来的动作发生之前已经完成的动作。注意：常与将来完成时连用的时间状语有： by (the time / the end of ) + 表示将来时间的短语和句子； before (the
53、end of ) + 表示将来时间的词语或句子； when, after等加上表示将来动作的句子等。 例如：By the year 2050, scientists probably will have discovered a cure for cancer.到2050年，科学家们可能已经找到治愈癌症的方法了。By the time you arrive in London, we will have been staying in Europe for two weeks.等你到达伦敦的时候，我们将已经在欧洲呆了两星期了。2. 在时间从句和条件从句中，现在完成时可以代替将来完成时，表示将来
54、某时业已完成的动作。例如：Youll get to like the subject after you have studied it for some time.在学习这个学科一段时间之后，你就会喜欢它的。Ill go and see the exhibition as soon as I have finished my work.我一做完作业就去看展览。3. 将来完成时还可以表示可能性，或设想。例如：Its five oclock；they will have arrived home by now. 已经五点钟了，他们现在应该已经到家了。（三）将来完成时与一般将来时的比较：有具体的时
55、间状语要用一般将来时。如：Mr Smith will return home on the first Sunday next month. 史密斯先生将于下月的第一个星期日回家。将来完成时的时间状语一般用介词by引入，如：Mr Smith will have returned home by next month. 到下个月史密斯先生将已回到家了。典例精析：1.
