85、关系。英语有两种语态：主动语态(active voice)和被动语态(passive voice)。主动语态表示主语是谓语动作的执行者，而被动语态则表示主语是谓语动作的承受者。一、被动语态的构成被动语态是由助动词be加及物动词的过去分词构成，如果有必要强调动作的执行者，动作执行者可以由介词by引出的短语表示。助动词be随主语的人称、数、时态和语气的不同而变化。A.十种常见时态的被动语态1.一般现在时主动语态：do被动语态：amisare doneWe clean the classroom every day.我们每天打扫教室。The classroom is cleaned by us ev

102、He was much flattered by her asking him to dinner.她邀请他吃晚饭，他受宠若惊了。（by表示原因）The snow was piled high by the gate.门口雪堆积得很高。（by表示地点）二、被动语态的用法英语中，大多数情况下用主动语态比较简练、有力。但是，被动语态也有其特殊的用途，它也是表达思想、描述事物的需要。人们通常在下列情况下使用被动语态：A.不知道或不必说出动作的执行者How is this word pronounced这个单词怎么发音？Scientists say that work is done whenever

108、n this city.他出生在这个城市。The school is situated in the suburbs.这所学校位于郊外。注意：被动语态中的by短语通常可以省去。但如果by短语是句子的重点所在，或者没有by短语全句的意思不完整时，则要保留by短语。The vegetables didnt taste very good.They had been cooked too long.蔬菜的味道不好，烧的时间太长了。（不需要动作的执行者）He arrived at the airport,where he was met by his friend.他到达了机场并受到朋友的迎接。（没有

110、也各不相同。A.主语+谓语+宾语“主语+谓语+宾语”结构中只有一个宾语，变为被动语态时，将宾语变为主语：They will discuss the plan at the meeting.他们将在会议上讨论这个问题。-The plan will be discussed at the meeting.这个问题将在会议上讨论。In the past the king possessed great wealth.过去国王拥有巨大的财富。n In the past great wealth was possessed by the king.过去，巨大的财富为国王所拥有。B.主语+谓语+间接宾语+

128、s on the oil painting.他注视着这幅油画。-His eyes were fixed on the oil painting.他的两眼注视着这幅油画。当宾语起状语作用，表示数量、重量、大小或程度时，不能用被动语态。This kind of dictionary costs ten dollars.这种字典价值十美元。The case weighs twenty kilos.这箱子重二十公斤。当宾语是同源宾语时，通常不能转换成被动语态。He laughed a hearty laugh.他由衷地笑了笑。She dreamt a sweet dream.她做了一个美梦。如果宾语是

132、人或by+抽象名词表动作的执行者，而后者则一般不用。The gate to the garden was locked by the girl.花园门被那个女孩锁上了。（被动结构）The gate to the garden was locked.花园门锁了。（系表结构）The tree was blown down by the high winds.那棵树被大风吹倒了。（被动结构）The tree was blown down when we saw it.我们看到那棵树时，它已经被吹倒了。（系表结构）注意：少数“连系动词be+用作表语的动词-ed形式”也带by短语。The old man
133、 was surrounded by small children.老人被孩子们团团围住。（被动语态）Guilin is surrounded by hills and mountains.桂林周围都是山。（系表结构）We were held up by fog.我们因雾受阻。（被动语态）The tree is known by its fruit.看到果子就知道是什么树。（系表结构）B.系表结构一般只用于一般现在时、一般过去时等少数几种时态；而被动语态可用多种时态。The composition is well written.这篇作文写得很好。（系表结构）The composition i

135、he moon is risen.月亮升起来了。She is grown up.她长大了。The leaves are fallen.树叶落了。We are prepared for the worst.我们已准备好应付最坏的情况。E.表示“充满”意思的“be+过去分词+with”结构多为系表结构。The mountain is covered with snow all the year round.这座山终年被积雪覆盖。The classroom was crowded with pupils.教室里挤满了学生。The lake is dotted with fishing boats.湖
136、里渔帆点点。The floor was piled with old books.地板上堆满了旧书。F.remain,feel,lie,stand以及become,grow等词+过去分词结构多为系表结构。The matter remained unsettled.这件事悬而未决。She felt disappointed.她感到失望。The road became crowded.道路拥挤了。G.句中有时间状语和地点状语时，一般为被动语态，反之为系表结构。The bank is closed.银行现在关门了。（系表结构）The bank is usually closed at six.银行通
137、常六点关门。（被动语态）He is married.他结婚了。（系表结构）五、主动形式表示被动意义英语中有些结构形式上是主动的，而表达的意义却是被动的。A某些不及物动词的被动意义英语中一般只有及物动词才用于被动语态，不及物动词不用于这种结构。但有些时候，某些不及物动词，其主动形式含有被动的意义。When did the accident occur事故是什么时候发生的？Ice-cream always goes well in hot weather.冰淇淋在暑天销路好。Does life exist on the moon月球上存在着生命吗？B一些表示“开始”、“结束”意思的动词Class
138、begins at eight.八点钟开始上课。The meeting ended up with warm applause.会议在热烈的掌声中结束了。C一些表示“运转”意义的动词The machine runs well.机器运转良好。His voice records well.他的音录下来很好。D当read,write,translate等动词与表示行为方式的状语连用时动词read,write,translate,act,add,wash,wear,cook,lock,sell,tear,cut,keep,feel,burn,strike,last等常和表示行为方式的状语连用，表示被动
139、意义。这些动词既是及物动词又是不及物动词。当主语是人时，是及物动词；当主语是物时，是不及物动词，即用主动形式表示被动意义。The book sells well.这书的销路很好。My pen writes smoothly.我的笔很好写。The play reads more easily than acts.这剧本易读不易演。提示：这些动词常和情态动词（多半是否定式）连用，表示被动。His car cant move.他的车不能开了。E表示状态特征的连系动词的被动意义有些表示状态特征的连系动词，如look,smell,taste,sound,prove,appear,turn out等主动形
140、式表示被动意义。Good medicine tastes bitter.良药苦口。What he said proved to be correct.他的话证明是正确的。The flowers smell sweet.这些花闻起来很香。Your sentence doesnt sound right.你这话听起来不大对头。F一些动词的进行时态可以表示一个被动的动作The meat is cooking.肉正在烧。The book is printing.这本书正在印刷之中。G有些作表语的不定式，在结构上是主动的，但在意义上却是被动的She is to blame.她应该受到责备。The hou
141、se is to let.此房出租。六、被动形式表示主动意义英语的被动形式表示主动的意义，主要见于状态被动语态句中。一般说来有以下几种情况。A反身动词的被动形式表示主动意义反身动词（及物动词+反身代词）作谓语时，其宾语反身代词，表示动作返回到执行者本身，主语既是动作的执行者，又是动作的承受者。由于反身动词具有这一特点，在被动结构中动作的承受者，也就是动作的执行者，在句中表现出主动的意义。He seats himself at the back of the classroom.他坐在教室的后面。-He is seated at the back of the classroom.他坐在教室的后
142、面。He lost himself in the forest.-He was lost in the forest.他在森林中迷了路。He dressed himself in a dark blue suit.-He was dressed in a dark blue suit.他穿着一套深蓝色的衣服。注意：有些介词短语作定语或表语时，也有被动的含义。The tall building under repair is an office building.正在修建的那座高楼是一座办公楼。The result is nnow under consideration.结果现在正在考虑中。个别
143、介词短语用冠词时表示被动的意义，不用冠词表示主动意义。The children are in the charge of this nurse.孩子们由这位护士照管。This nurse is in charge og the children.这位护士负责照看孩子们。B“引起感情”等动词的被动形式表主动意义The teacher is satisfied with what he said.老师对他所说的感到满意。We are opposed to unjust wars.我们反对非正义的战争。We are prepared to accept his proposal.我们准备采纳他的建议
144、。He was tired with playing all day.玩了一整天他感到很疲倦了。C某些表示定位、移位的动词The earth is tilted a little.地球有点儿倾斜。Hundreds of soldiers were stationed around the prison.数百个士兵驻扎在监狱周围。The village is located at the foot of a hill.这个村庄坐落在山脚下。D不及物动词的-ed形式与be连用表示主动意义Spring is come.春天来了。The moon was set and it was very dar
145、k.月亮落了，天很黑。He is advanced in years.他年纪很大了。E表示终止动词的-ed形式He is done with it.他做完了这件事。My fever is gone,but I still have a cough.我的烧已经退了，但还有点儿咳嗽。F一些习惯用法He was graduated from Beijing University.他毕业于北大。You are mistaken.你弄错了。He is retired.他退休了。G被动的祈使句Do be seated.请坐！Be prepared,please.请准备好。Get washed.洗吧。Be
146、concerned more about the well-being of the masses.多关心群众的生活。He was married in Beijing.他是在北京结婚的。（被动语态）虚拟语气第三章虚拟语气虚拟语气（the subjunctive mood），又称假设语气，是谓语动词的一种形式，表示说话人叙述的内容与事实相反，在现实中并不存在，或实现的可能性很小。一、动词的语气语气用来区别讲话人对某一行为或事情的看法和态度。英语中的语气(mood)有三种，分别是陈述语气、祈使语气和虚拟语气。1.陈述语气陈述语气一般用来叙述事实或就事实提出询问，主要用于陈述句、疑问句和某些感叹句
147、。Where there is a will,theres a way.有志者事竟成。Can you help me carry the box upstairs你能帮我把箱子搬到楼上吗？How I missed the life in the countryside!我多么想念乡村的生活啊！2.祈使语气祈使语气表示说话人向对方提出请求或下达命令。Come this way,please!请这边走。Dont make any noise,will you别吵，行吗？Do be careful when crossing the street.过马路时一定要小心。3.虚拟语气虚拟语气表示动作或状
148、态不是客观存在的事实，而是说话人的主观愿望、假设或推测等。If I were a bird,I could fly in the air.如果我是一只小鸟，我就能在空中飞行。I wish it were spring all the year round.但愿四季如春。May good luck be yours!祝你好运！二、条件句中的虚拟语气英语中条件从句有两类，一类是真实条件句，另一类是非真实条件句。如果假设的情况可能发生，是真实条件句；如果假设的情况是不存在的或不大可能发生的，则是虚拟条件句。A真实条件句真实条件句表示的假设是可能发生或实现的，主句和从句的谓语动词都要用陈述语气。If
149、he doesnt come at 8,we wont wait for him.如果他八点不来，我们就不等他了。If a flood happened in the past,there was usually a great loss of life and property.过去发生洪水的话，常有很大的生命和财产损失。We shall go there unless it rains tomorrow.如果明天不下雨，我们将去那里。Ill let you use my bike on condition that you keep it clean.如果你能保持车子干净，我就让你用我的自
150、行车。B非真实条件句在含有非真实条件句的复合句中，主句和从句的谓语动词都要用虚拟语气，其构成有三种形式：与现在事实相反if条件句的谓语：were did主句的谓：would(couldshouldmight)+do与过去事实相反if条件句的谓语：had done主句的谓：would(couldshouldmight)+have done与将来事实相反if条件句的谓语：didwere主句的谓：should do would(couldshouldmight)+do were to do1表示与现在事实相反的条件条件从句用动词的过去式（be动词用were），主句用should（第一人称）或woul
151、d（全部人称）+动词原形。可用情态动词could,might代替should,would表示情态。If it were Sunday tomorrow,I would go and see my friends.明天要是星期天的话，我就去看望我的朋友。If I were you,I should go and try.我要是你，我就去试试。If wishes were horses,beggars might ride.如果幻想能成为马匹，叫花子都有了坐骑would go if they treated me like a slave.要是他们把我当奴隶对待，我就走。2表示与过去事实相反的条件
152、条件从句用动词的过去完成时，主句用should（第一人称）或would（全部人称）+have done，也可用could,might代替should,would。If I had known your telephone number yesterday,I would have telephoned you.如果昨天我知道你的电话号码，我就给你打电话了。If it had not rained this morning,I should have gone shopping.今天早上要是没下雨，我就去买东西了。The flood might have caused great damages
153、 to the people if we had not built so many reservoirs.倘若我们没有修建这么多的水库，洪水就会使人民遭受巨大的损失。3表示在将来不太可能实现的条件表示在将来不太可能实现的条件从句有三种形式：weredid条件从句用动词的过去式（be动词用were），主句用should（第一人称）或would（全部人称）+动词原形。也可用could,might代替should,would。If he were here tomorrow,I would speak to him.明天如果他在这里的话，我就和他谈谈。If you dropped the glas
154、s,it would break.你要是把杯子掉下来，会打碎的。If she had time,she could help me.她要是有时间，就会帮我了。should do条件从句中不管什么人称都用should do，可表示有偶然实现的可能性。If it should rain,the crops could be saved.假如下雨，庄稼可能就有救了。We would trust him if he should be honest.如果他真是诚实的，那我们就相信他。were to do条件从句用were+to do。这种形式比较正式，常出现在书面语中，其假设成份很大，实现的可能性很小
155、。If I were to do the work,I should do it in a different way.要是我做这项工作，我就会以不同的方式去做。If the headmaster were to come,what would we say to him假如校长来了，我们对他说什么呢？对比：将来不太可能实现的三种非真实条件句中的虚拟语气对比If it snowed tomorrow,I would stay at home.如果明天下雪的话，我就留在家里。（常用形式）If it should snow tomorrow,I would stay at home.如果明天下雪的
156、话，我就留在家里。（可能性较小）If it were to snow tomorrow,I would stay at home.如果明天要下雪的话，我就留在家里。（可能性最小）C省略if的条件句在书面语中，非真实条件句中有were,had,should时，可以省略if，而把were,had,should放在主语前，用倒装结构。Were it necessary,I might go without delay.如果需要的话，我可以立即去。（=If it were necessary.）Had you taken my advice,you wouldnt have failed in the
157、 exam.你要是听了我的建议，就不会考试不及格了。（=If you had taken my advice.）Should I have time,I would call on her.要是有时间，我就去看她。（=If I should have time.）D错综条件句虚拟条件句中的主句和从句涉及的动作发生的时间不一致，这时主句和从句的谓语形式应按照各自动作发生的实际时间来表达。If you hadnt watched TV yesterday,you wouldnt be so sleepy now.如果你昨天不看电视，你现在也就不会这么困了。（从句yesterday说明过去，主句no
158、w说明现在）If they had left home early this morning,they would arrive in half an hour.如果他们今天一早就离开家的话，再过半小时他们就该到了。（从句说明过去，主句说明将来。）If you hesitated this moment,you might suffer in the future.如果你此刻犹豫不决，你将来会吃苦头的。（从句说明现在，主句说明将来）注意：在很多情况下，我们也可以用was来代替当主语是第一人称或第三人称单数时的were。If were here tomorrow.也可以说成：If he was
159、here tomorrow.I wish I were a bird.也可以说成：I sish I was a bird.但倒装句型中的were不可被was来替换。Were I in your position,I would not do it.如果我处在你的位置，我是不会干这件事的。E含蓄条件句非真实条件句中的条件从句有时不表达出来，只暗含在上下文中，这种句子叫做含蓄条件句。含蓄条件句大体有三种情况：1条件暗含在短语中He would not get such a result without your help.没有你的帮助，他就不会有今天的成果。(条件暗含在介词短语without yo
160、ur help中)But for you,I could not be recovered so soon.要不是有你，我就不会恢复得这么快。(条件暗含在But for you中)This same thing,happening in the past,would lead to a disaster.同样的事，如发生在过去，就会酿成大祸。(条件暗含在分词短语happening in the past中)He must have been there,or he never could know the place so well.他一定是去过那儿，否则他绝不会对那个地方如此熟悉。(暗含条件
161、是连词or)2条件可根据上下文推理出It would do you no good.这可能会对你没好处。(条件可能是if you should give up the job如果你放弃这项工作的话)They could have won.他们本来是会赢的。(条件可能是if they had been patient如果他们有耐心的话)Such mistakes could have been avoided.这种错误完全能避免。（条件可能是if you had been more careful如果你更加小心一点的话）Why didnt you tell me about it I shoul

164、ding等词表示if）To talk with her,you would know she could not hear well.如果你同她交谈，你就会知道她的听力不好。（动词不定式带有假设的意思，相当于If you should talk with her.）Left to himself,he could not have finished the work.要是放任他的话，他是不可能完成工作的。（动词的-ed形式表示条件If he had been left to himself.）提示：在很多情况下，虚拟式已变成习惯说法，很难找出其暗含的条件。You wouldnt know.你不
165、会知道。I would like to go with you.我愿意和你一起去。三、虚拟语气在各种从句中的用法虚拟语气除主要用于非真实条件句外，还可用在部分主语从句、宾语从句、表语从句、同位语从句、定语从句和状语从句之中。A名词性从句中的虚拟语气主句中的动词、名词、形容词如表示要求、建议、命令或愿望等含义，与其相关的名词性从句（主语从句、宾语从句、表语从句和同位语从句）中的谓语动词要用虚拟语气。1主语从句中的虚拟语气主语从句通常用于“It is+形容词名词动词的-ed形式+that.”结构。主语从句中是否用虚拟语气取决于所用的形容词或动词的-ed形式，其谓语动词常用“should+动词原形”
166、（美国英语常省略should，只用动词原形）。表示建议或命令It is important that we(should)work out a study plan.重要的是我们要制订出一个学习计划。It will be better that we(should)meet some other time.最好我们在另一个时间见面。It is suggested that each student(should)sing a song in English.有人建议每个学生都要唱一首英文歌曲。It is demanded that he should leave at once.要求他立刻离开

168、tial,vital,natural,strange,proper等动词的-ed形式：arranged,suggested,ordered,required,desired,demanded,proposed等It is necessary that the program(should)be loaded into the computer.有必要把程序输入电脑。It is strange that he should have learned so much in such a short time.很奇怪他竟然在如此短的时间内学了那么多的东西。It is desired that we(
169、should)get everything ready by tonight.希望一切在今晚前准备就绪。2宾语从句虚拟语气常用在表示要求、建议、命令或愿望的动词后的宾语从句中。常见的宾语从句中需用“should+动词原形”的动词有：一个坚持：insist两个命令：order,command三个建议：suggest,advise,propose四个要求：demand,require,ask,desire在suggest（建议）,order(命令),propose(建议),insist（坚持要做）,command(命令)，request（要求），advise（建议）等动词后的宾语从句中，谓语动词用

171、气。suggest作“建议”解时，用虚拟语气，作“使想起、暗示”解时，用陈述语气。His silence suggested that he agreed with my decision.他的沉默暗示他赞同我的决定。（暗示）He suggested that I(should)stick to my decision.他建议我坚持自己的决定。（建议）insist作“坚决要求”解时，用虚拟语气，作“坚持认为”解时，用陈述语气。He insists that doing morning exercises does good to peoples health.他坚持认为做早操对健康有益。（强调
172、）He insists that he(should)do morning exercises every day.他坚持每天都要做早操。（要求）在动词wish后的宾语从句中用虚拟语气，表示不可能实现的愿望。一般过去时weredid表示目前不可能实现的愿望I wish I were a bird.但愿我是一只小鸟。I wish I knew the answer.我要是知道答案就好了。过去完成时had done表示过去不可能实现的愿望I wish she had taken my advice.那时她要是接受我的建议就好了。I wish that I had seen her yesterda
173、y.真希望我昨天见过她。过去将来时wouldcould do表示将来没有把握或不可能实现的愿望I wish you would stay an hour longer.我希望你再呆一个小时。I wish it could stop raining.但愿雨能停。提示：由于wish和hope的汉语意思差不多，在使用上往往容易出错。wish一般表示“希望”、“但愿”，表示不可能实现的愿望，后接从句时要用虚拟语气；hope表示“希望”，指可以实现的希望，后接从句时用陈述语气。The students hope that their football team will win the game.学生们
174、希望他们的足球队获胜。（可能实现）I wish I could see him now.我希望现在就能看到他。（不可能实现）3表语从句和同位语从句中的虚拟语气在表示建议、劝告、命令等含义的名词后的表语从句和同位语从句中，谓语动词要用“should+动词原形”结构。My advice is that you(should)practise speaking English as often as possible.我的建议是你尽可能经常地练习说英语。The demand is that the composition(should)be written on one side only.按照要求

386、A动词的-ed形式在句中作状语和表语时，它的逻辑主语一般来说就是句子的主语，-ed形式和主语之间是被动关系。Locked up,he had no way to escape.他被锁了起来，没有办法逃跑了。Lost in thought,he almost ran into the car in front of him.他陷入了沉思，几乎撞到了前面的汽车。She became discouraged at the news.听到这个消息，她泄气了。Though it was 1000 a.m.,the door of the shop remained locked.尽管已经是上午10点了，
387、商店的门仍然锁着。B当动词的-ed形式在句中作定语时，它的逻辑主语是被它修饰的名词，它和名词之间是被动关系。The first textbooks written for teaching English as a foreign language came out in the 16th century.第一批编写出来作为英语教材的课本是16世纪出版的。The computer center,opened last year,is very popular among the students in this school.去年开办的计算机中心深受这所学校的学生喜爱。A lighted ca

389、rned upside down.Thieves obviously had broken in.我们回到家发现整幢房子被翻得乱七八糟,很明显小偷闯进来了。D动词的-ed形式有时可有其独立的逻辑主语，常用作状语（详见“第8章独立主格结构”）。Everything done,we went home.一切事情都做完了，我们就回家了。All our money run out,Henry had to find another job.钱都用完了，亨利不得不再找一份工作。He was lying on the grass,his hands crossed under his head.他躺在草地
390、上，头枕着双手。All things considered,the planned trip will have to be called off.考虑到所有的情况，原来计划好的旅行不得不取消。E动词的-ed形式作独立成分。动词的-ed形式的一些固定词组也可在句中作独立成分，不受逻辑主语的限制。Put frankly,I dont agree with what he said.坦白地说，我不同意他所说的。Given the general state of his health,it may take him a while to recover from the operation.考虑到
391、他一般的身体状况，手术后的恢复可能需要一段时间。D动词的-ed形式作状语独立主格结构第八章独立主格结构非谓语动词作状语时，它的逻辑主语应该是句子的主语。但有时非谓语动词带有自己的主语，从而在结构上与主语不发生关系，我们称之为独立主格结构（Absolute Construction）。其实，所谓“独立主格结构”也并非真正独立，它还是一种从属的结构。一、非谓语动词独立主格结构在独立主格结构中，非谓语动词和它前面的名词或代词存在着逻辑上的主谓关系。Such an able man to help you，you will surely succeed sooner or later.有这么能干的人来
392、帮你,你迟早一定会成功的。（such an able man和to help you之间存在着主谓关系）=Since such an able man will help you,you will surely succeed sooner or later.He seating himself at the desk,his mother began to tell him a story.他在书桌旁坐好后，他母亲开始给他讲故事。（seating himself at the desk拥有了自己的逻辑主语he，注意是“主格”）=When he seated himself at the de
393、sk,his mother began to tell him a story.The key to the bike lost,he had to walk to school.由于丢了自行车钥匙，他只好步行去学校。（lost的逻辑主语是the key，lost也可以用完成式having been lost）=Because the key to the bike had been lost,he had to walk to school.A不定式“独立主格结构”在“逻辑主语+动词不定式”结构中，动词不定式和它前面的名词或代词存在着逻辑上的主谓关系。这种结构也可用一个从句或并列分句来表达。
394、1动词不定式用主动的形式在独立主格结构中，动词不定式和它前面的名词或代词存在着逻辑上的主谓关系。His mother to come tonight，he is busy preparing the dinner.他母亲今晚要来,他正在忙着准备饭菜。（=As his mother is to come tonight,he is busy preparing the dinner.）will you go to the comcert tonight你今晚去听音乐会吗？sorry.So many exerise-books to check,I rially cant afford any t

398、yone wasready)The chairman began the meeting,everyone being seated.每个人坐好后，主席开始开会。（相当于一个时间状语从句after everyone was seated）2表示原因的-ing形式作“独立主格结构”The boy leading the way,we had no trouble finding the strange cave.由那个男孩带路，我们没有困难就找到了那奇怪的洞。（相当于一个原因状语从句Because the boy led the way）Many eyes watching him,he fel
399、t a bit nervous.许多眼睛看着他，他感到有点儿紧张。（相当于一个原因状语从句As many eyes were watching him）必背：含有being的独立主格结构。It being National Day today，the streets are very crowded.今天是国庆节,街上很拥挤。=As it is National Day today,the streets are very crowded.There being no further business to discuss,we all went home.没有别的事可讨论，我们都回家了。=A
400、s there was no further business to discuss,we all went home.3表示条件的-ing形式作“独立主格结构”Time permitting,we will have a picnic next week.时间允许的话，我们下星期将进行一次野炊。（相当于一个条件状语从句If timepermits)My health allowing,I will work far into the night.我的健康许可的话，我愿工作到深夜。（相当于一个条件状语从句If my health allows）4表示方式的-ing形式作“独立主格结构”The
401、students are walking in the school happily,each wearing a card in front of his chest.学生们快乐地在学校里走着，每个人胸前都带着一张卡。（相当于一个并列分句and each wears a card in front of his chest）The boy lay on the grass,his eyes looking at the sky.男孩躺在草地上，眼睛看着天空。（相当于一个并列分句and his eyes were looking at the sky）C-ed形式“独立主格结构”与逻辑主语+动
402、词的-ing形式一样，如果-ed形式的逻辑主语和句子的主语不一致的话，就需要用-ed形式的独立主格结构。The book written in simple English,English beginners were able to read it.该书是用简单英语写的，英语初学者也能看懂。=As the book was written in simple English，English beginners were able to read it.The workers worked still harder,their living conditions greatly improve
403、d.由于工人们的生活条件大大提高，他们工作得更起劲了。=As their living conditions were greatly improved,the workers worked still harder.He was listening attentively in class,his eyes fixed on the blackboard.他上课专心听讲，眼睛紧盯着黑板。=He was listening attentively in class,and his eyes were fixed on the blackboard.The task completed,he h
404、ad two monthsleave.任务完成以后，他休了两个月的假。（=When the task had been completed,he had two monthsleave.）比较：动词不定式表示动作没有发生或即将发生，动词-ed形式表示动作已经结束，动词-ing形式往往表示动作正在进行。The manager looks worried，many things to settle.经理看上去很着急,有这么多的事情要处理。（事情还没有处理，而且是由经理本人来处理，用不定式to settle）The manager looks relaxed,many things settled.
405、许多事情已经处理好了，经理看上去很轻松。（事情已经处理好了，用动词-ed形式settled表示动作已经结束）The food being cooked,the boy was watching TV.小孩一边做饭，一边看电视。（两个动作同时进行）The food cooked,the boy went to bed.饭做好了，小孩去睡了。（两个动作有先后，饭已做好，小孩才去睡觉的）一、动词独立主格结构“逻辑主语+being+其他”是独立主格结构中的“逻辑主语+动词-ing形式”的一种形式。在这种结构中，being往往可以被省去，这种省去being的结构，称之为无动词“独立主格结构”。A逻辑主语
406、+名词Ten students entered for the competition,the youngest a boy of 12.十个学生报名参加了这次竞赛，年纪最小的是个12岁的男孩。（the youngest和a boy of 12之间省去了being）注意：独立主格结构中的being在下列两种情况下一般不能省略，一是在“There being+名词”结构中，二是在逻辑主语是代词的情况下。There being no bus,we had to walk home.由于没有公共汽车，我们只好走回家。It being Sunday,all the offices are closed

418、 more spoken,she left the meeting room.她没再四、独立主格结构的句法功能独立主格结构在句中除了能充当原因状语、时间状语、条件状语和伴随状语外，还能作定语。在形式上，“独立主格结构”可位于句首、句中或句尾，并通常用逗号与主句隔开。A作状语独立主格结构作状语，其功能相当于一个状语从句或并列分句。1表示时间Night coming on,we put ourselves up in a small hotel.夜幕降临，我们在一家小旅馆住了下来。（=When night came on,we put ourselves up in a small hotel.）

428、性从句由一个主句和一个或一个以上的从句构成的句子叫复合句。名词性从句在复合句中起名词的作用，它包括主语从句、宾语从句、表语从句、同位语从句四大类，在句中分别用作主语、宾语、表语和同位语。一、一、引导名词性从句的关联词Athat连词that本身没有意义，在从句中不担任任何句子成分，在宾语从句中有时可省略。I hear(that)he has joined the football club.我听说他已经加入了足球俱乐部。That light travels in straight line is known to all.众所周知，光是以直线传播的。It so happens that I kn
429、ow the man.碰巧我认识那个。Is it certain that they will win他们一定会赢吗Bwhether和if连词whether和if本身有意义（解释是否），在从句中不可省略。1whether可以连接所有的名词性从句，而if只能引导宾语从句。I didnt know whether he would attend the concert.我并不知道他是否参加音乐会。（宾语从句，可用if代替whether）The question is whether it s worth trying.问题是值不值得试一试。（表语从句，不可用if代替whether）Whether

431、had hurt her feelings.瑞恩担心是否伤害了她的感情。3if既可引导语从句，也可引导宾语从句。如果用if会引起歧义，应避免使用if，而用whether。Please let me know if you want to join us.请告诉我你是否想加入我们。（if引导的从句可被看成是宾语从句，if表示是否）Please let me know if you want to join us.如果你想加入我们的话，请告诉我一声。（if引导的从句可被看成是条件状语从句，if表示如果）Please let me know whether you want t join us.请告
432、诉我你是否想加入我们。（为避免引起歧义，可用whether表示是否）Cwho,whom,whose,what,which连接代词who,whom,whose,what,which等在从句中既起连接作用，同时又担当主语、宾语、定语、表语等成分。No one knows who he was waiting for.没人知道他当时在等谁。We are worrying about what we should do next.我们正在为下一步该怎么办而烦恼。Tell me whos house it is.告诉我这是谁的家。Let me know which train you will be a

435、；whomever=anyone whom（whoever的宾格形式）。Whoever comes to the club is welcome.不论谁来参加这个俱乐部都欢迎。Whatever is worth doing at all is worth doing well.凡是值得做的就值得做好。They ate whatever they could find o the deserted island.他们在荒岛找到什么就吃什么。You may do whatever you will.你可做任何你想做的事。Ill take whichever book interests me.我愿
436、买任何让我感兴趣的书。Whosever book is overdue will be fined.不管谁的书过期未还都要被罚款。比较：连接代词whoever在宾语从句中作主语，whomever作宾语从句中宾语。You may offer he book to whoever wants it.你可把这本书给任何想要的人。（此句中不能使用whomever，因为whoever在宾语从句中作wants it的主语）You may offer the book to whomever you like.你可把这本书给任何你喜欢的人。（whomever在宾语从句中作you like的宾语）一、表语从句
