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1.被动语态是由助动词be加动词的过去分词构成的，如果要强调动作的执行者，动作执行者可以用介词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。in the near future，more advances in the robot technology will be made by scientists.在不久的将来，科学家在机器人技术方面将取得更多的进步。this coastal area was named a national wildlife reserve by the government last year.这个沿海地区去年被政府确定为国家野生动物保护区。2.被动语态的形式。一般现在时的被动语态is/am/are done一般过去时的被动语态was/were done一般将来时的被动语态will/shall be done过去将来时的被动语态would be done现在进行时的被动语态is/am/are being done过去进行时的被动语态was/were being done现在完成时的被动语态have/has been done过去完成时的被动语态had been done将来完成时的被动语态will have been done过去将来完成时的被动语态would have been done含情态动词的被动语态情态动词be donetraditional folk arts of tianjin like paper cutting are being exhibited at the culture show.像剪纸这样的天津传统民间艺术正在文化展示区展出。all visitors to this village are treated with kindness.所有到这个村的游客都受到了善意的对待。after getting lost in a storm，a member of the navy team was rescued four days later.迷失在暴风雨中四天后，一名海军成员被救起。experiments of this kind had been conducted in both the u.s.and europe well before the second world war.早在第二次世界大战之前这种实验在欧洲和美国就进行过。how many expressways will have been completed by the end of next year?到明年年底将建成多少条高速公路？二、被动语态的用法1.不知道谁是动作的执行者或没有必要说出谁是执行者。scientists say that work is done whenever a force moves.科学家们说，力移动时就做了功。2.需要强调或突出动作的承受者。a new hope school will be opened in our village.我们村将开办一所新的希望学校。(强调a new hope school)books and newspapers in the reading room mustnt be taken away.阅览室里的书和报纸禁止被拿走。(强调books and newspapers)3.为了使语气委婉，避免提及自己或对方而使用被动语态，或由于修饰的需要，使用被动语态，使句子得到更好的安排。the construction of the new lab must be completed by the end of next month.新实验室的建设必须在下个月月底前完成。youve been told many times not to make the same mistake.你已经被多次告知不要犯同样的错误。 三、主动语态与被动语态互换1.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.the plan will be discussed at the meeting by them.他们将在会议上讨论这个计划。2.主语谓语间接宾语直接宾语。在这个句型中，谓语动词后跟两个宾语。变成被动语态时，一般将通常指人的间接宾语转化成主语，但有时也可将指物的直接宾语转化成主语。his father bought him a computer last week.he was bought a computer by his father last week.上周他父亲给他买了一台电脑。3.主动语态变为被动语态的几种特殊情况。(1)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足语时，在主动结构中不定式to要省略，但变为被动语态时，要加to。my grandfather was made to work for 10 hours a day.我的爷爷一天要工作十个小时。(2)含有宾语从句的主动语态变为被动语态时，通常用it作为被动结构的形式主语，从句放在句子后面，这类动词有：know，say，believe，find，think，report等。it is said that part of the aircraft wing found on reunion island is from the missing mh370 plane.据说在留尼汪岛被找到的部分机翼是来自失联的mh370的。its well-known that sichuan province provides a perfect natural habitat for pandas.众所周知，四川省是熊猫最佳的天然栖息地。(3)有些动词虽为及物动词，但宾语并非动作承受者，不能转换，这些动词有have，hold(容纳)，suit，fit，lack，contain，cost，last，mean等。the hall can hold 500 people.这个大厅能容纳500人。the book contains six chapters.这本书包含六章。四、主动形式表被动意义的情况1.一些表示感官意义的连系动词，如taste(品尝起来)，sound(听起来)，feel(摸起来)，smell(闻起来)，prove，turn，grow，fall，keep等，后接形容词或名词构成系表结构。the flower smells sweet.这朵花闻起来香。good medicine tastes bitter.良药苦口。2.一些不及物动词，如open，close，shut，lock，move，read，write，wash，sell，clean，cook，burn，draw，cut，wear，begin，start，finish，end，keep等，表示主语的某种属性、特征或所处状态(常与easily，quickly，well等副词连用)，而非强调动作本身时，通常用主动形式表示被动意义。the table cant move.这桌子移不动。the door locks easily.这门容易锁上。3.在“be形容词to do”结构中，不定式在作表语的形容词后充当状语，同时，主语是不定式结构的逻辑宾语，此时习惯上以主动形式表示被动意义。这些形容词通常有difficult，hard，cheap，expensive，enough，sure，fit，nice，dangerous，comfortable，exciting，good，important等。the text is easy to understand.这篇课文容易理解。4.在need(want，require，deserve，etc.)doing句型中，动名词doing相当于动词不定式的被动式to be done，在意思上没有多大差别。our classroom wants/needs/requires cleaning.our classroom wants/needs/requires to be cleaned.我们的教室需要打扫。五、被动结构和系表结构的区别1.被动语态中的过去分词是动词，多强调动作；系表结构中的过去分词相当于形容词，多强调状态。前者通常可用by人或by抽象名词表动作的执行者，而后者则一般不用。the tree was blown down by the strong winds.那棵树被强风吹倒了。(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)2.系表结构一般只用于一般现在时、一般过去时等几种时态，而被动语态可用于多种时态。the composition is well written.这篇作文写得很好。(系表结构)the composition is being written.这篇作文正在被写。(被动语态)学法点拨巧记被动语态被动语态强调“宾”，用be加上“过去分”。“be”要随着主语变，人称时态要弄准。“行为对象”作主语，逻辑主语“by”来引。原句若有双宾语，一变“主”来一保“宾”。“间宾”要把主语变，原来“直宾”还是“宾”。“直宾”要把主语变，“间宾”前加“to”最称心。原句“宾补”变“主补”，位置不必挪寸分。情态动词变“被动”，情态加be加过分。“短语动词”变“被动”，相当“及物”莫疑心。不过其后“介”或“副”，变后还是要承认。.用所给词的适当形式填空1.its said that the long bridge will_be_built(build)in two months.2.where to have the meeting is_being_discussed(discuss)now.3.which language is the most widely spoken(speak)in the world?4.the lost boy

parents every year.3.the children will sing an english song.(改为被动语态)an english song will be sung by the children.4.you neednt do it now.(改为被动语态)it neednt be done by you now.5.people use metal for making machines.(改为被动语态)metal is used for making machines.6.he made me do that for him.(改为被动语态)i was made to do that for him.7.they are watching the football match.(改为被动语态)the football match is being

b.will be madec.are being made d.have been made答案b解析句意：正如报道的那样，要加快供给侧结构性改革，今后几年要付出更多的努力。根据时间状语in the years ahead可知，此处要用一般将来时，再结合主语more efforts与动词make之间为被动关系可知答案为b。2.the students have been working hard on their lessons and their efforts _ with success in the end.a.rewarded b.were rewardedc.will reward d.will be rewarded答案d解析句意：学生们一直努力学习功课，他们的付出最终会获得成功的。由句意可知，reward这一动作发生在have been working之后，故用将来时态；reward和efforts之间为被动关系，所以用一般将来时的被动语态。故选d。3.to my delight，i _ from hundreds of applicants to attend the opening ceremony.a.was chosen b.was being chosenc.would choose d.had chosen答案a解析句意：令我高兴的是，在几百个申请者中我被选中参加开幕式了。首先，句子主语i和choose是被动关系，所以要用被动语态；其次，本句是对过去所发生事情的客观描述，所以用一般过去时。4.my washing machine _ this week，so i have to wash my clothes by hand.a.was repaired b.is repairedc.is being repaired d.has been repaired答案c解析句意：我的洗衣机这周正在被修理，因此我不得不手洗我的衣物。由时间状语this week可知要表达的动作和现在有关，排除a。且洗衣机是被修理的，因此用现在进行时的被动语态，据此排除b、d。5.a rescue worker risked his life saving two tourists who _ in the mountains for two days.a.are trapping b.have been trappedc.were trapping d.had been trapped答案d解析句意：一位救援人员冒着生命危险挽救了两个被困在山上两天的游客。游客被困发生在被救之前，表示过去的过去，因此要用过去完成时态。6.unless some extra money _，the theatre will close.a.was found b.findsc.is found d.found答案c解析句意：除非找到额外的资金，要不然，这家剧院就得关门了。由句意可知，此处是unless引导的条件状语从句，主句用一般将来时，从句用一般现在时表将来，排除a、d两项。题中从句的主语some extra money与动词find之间为被动关系，因此要用被动语态，故排除b项，选c。.词形变换1.its ok to leave an electrical (electricity) appliance on so long as you are using itif not，turn it off.2.the president is the most powerful(power) man in america.3.it was the most amazing (amaze) experience of my life.4.money doesnt always bring happiness (happy).5.i had not enough confidence (confident) to go ahead.单项填空1.instead of praising your kids for their intelligence，you should _ your praise on the effort they put into succeeding at tasks，experts say.a.conduct b.circulatec.concentrate d.allocate答案c解析句意：专家们说，你应该注重表扬孩子们成功完成任务所作出的努力，而不应该夸奖孩子聪明。根据句意可知，这里表示把表扬集中在孩子的努力上，故用concentrate on 表示“把集中在上”。conduct实施，安排；circulate(使)循环；allocate分配，配给。2.the room is empty except for a bookshelf_in one corner.a.standing b.to stand c.stands d.stood 答案a解析bookshelf 和后面动词stand是主动关系，且stand这一动作正在发生，故选a。3.give me a chance，_ ill give you a wonderful surprise.a.if b.or c.and d.while答案c解析“祈使句and陈述句”结构中，and为并列连词，表顺承关系，相当于“if you give me a chance，ill give you a wonderful surprise.”。4.you are not allowed to go into the meeting room.a secret plan_there.a.is being discussed

carried outc.is being carried out d.has been carried out答案a解析句意：上个月，我被派往这个村子，去看看过去两年中，发展计划执行得怎样了。carry out发生在i was sent之前，所以要用过去完成时。7.john was so sleepy that he could hardly keep his eyes _.a.open b.to be openedc.to open d.opening答案a解析考查“keep宾语宾补”结构，形容词 open 作宾补。8.have you moved into the new house?not yet，the rooms_.a.are being painted b.are paintingc.are painted d.are being painting答案a解析the rooms 与paint之间是被动关系，由语境可知应使用现在进行时的被动语态。9.joining the firm as a clerk，he got rapid promotion，and _ as a manager.a.ended up b.dropped outc.came back d.started off答案a解析句意：作为一名公司职员，他迅速得到提升，最后成为一名经理。end up

sounded答案a解析句意：你觉得他的讲话怎么样？哦，很棒，他讲的话听起来像诗歌。did，was，said用了过去时，决定sound要用过去时，sound是系动词，不能用于被动语态。一般来说，不及物动词、表静态的及物动词不能用于被动语态。.阅读理解awith 3d technology，the images(影像)on screen create a more realistic experience.but now researchers are developing new technology which will provide you with an even more immersive(使人身临其境的)experience.this new technology has been named“9d tv”and it aims to stimulate(刺激)all your five senses.9d tv is actually the most advanced technology up to now.after finding that the depth and distance offered by 3d was not enough for a fully immersive experience，researchers from england started on a project to create a 9d television.9d tv will perfectly use your senses of touch，taste and smell in order to produce the proper emotional response(感情的反应)to whatever you are seeing.this means that tv programmes will no longer rely only on the content of the actors performances in order to touch peoples hearts.the technology behind 9d tv is based on the idea that different regions of our hands are connected to different emotions.a device(设备)being developed will touch your hands in a way that a range of emotion from happiness and sadness to excitement and fear can be conveyed(传达).though it is unlikely that 9d tv will be ready to hit the market soon，one thing is clearthe technology is available.if researchers manage to combine the five senses，they are going to be able to create a unique chance to enjoy a fully immersive viewing experience.【语篇解读】本文向我们介绍了未来的9d电视会是什么样子。1. what does 9d tv aim to
