1.文中加黑处都使用了_________，其结构为________。 2.加黑处①、③都是_________________语态；加黑处②、④都是________________语态；加黑处⑤是_______________ 语态。 被动语态 be done 一般过去时的被动 一般现在时的被动 现在完成时的被动 第一部分　谓语动词的被动语态 一、被动语态的概念及构成 1.概念：英语中动词有主动语态和被动语态之分。如果主语是动作或状态的发出者，动词就用主动语态；如果主语是动作或状态的承受者，动词就用被动语态。 2.构成：被动语态由“be＋动词的过去分词”构成，被动语态的时态、人称和数的变化主要体现在be的变化上，其变化形式与系动词be完全一样。 In my hometown，there is always a harvest supper for the farmers after all the wheat has been cut. 在我的家乡，所有的小麦收割完毕后，农民们总会有一顿丰收宴。 语法知识精讲 二、 被动语态的使用场合 1.不知道或没有必要说明动作的执行者是谁时。 2.强调动作的承受者，而不强调动作的执行者时。强调动作的执行者时，执行者由介词by 引出。特别注意“be＋过去分词”并不一定都是被动语态，有时是系表结构： (1)当“be＋过去分词”表示动作时为被动语态，be为助动词，be后面的过去分词是主要动词，动作的承受者是主语，动作的执行者可由介词by 引出。 The window was broken by Jim last night. 昨晚窗户被吉姆打破了。 (2)当“be＋过去分词”表示主语所处的状态时为系表结构，be是连系动词，be 后面的过去分词是表语，相当于形容词。 The window is broken.这扇窗户是破的。 三、各种时态的被动语态 1.一般现在时的被动语态：am/is/are＋done The little girl is looked after by Granny every day. 奶奶每天照顾那个小女孩。 2.一般过去时的被动语态：was/were＋done I was brought up by my aunt. 我是由姑姑带大的。 项目 一般时态 进行时态 完成时态 现在 am/is/are done am/is/are being done has/have been done 过去 was/were done was/were being done had been done 将来 shall/will be done / shall/will have been done 3.一般将来时的被动语态：shall/will＋be＋done I will be given a chance to play in this game again. 我将再一次获得参赛的机会。 4.现在进行时的被动语态：am/is/are＋being＋done The bridge to the road is being repaired.通往那条路的大桥正在维修。 5.过去进行时的被动语态：was/were ＋being＋done The last time I went back to my hometown，a big power station was being built there. 上次我回家乡时，那里正在修建一个大电厂。 6.现在完成时的被动语态：have/has＋been＋done I have been told the sports meeting might be put off. 有人告诉我运动会可能会延迟。 7.过去完成时的被动语态：had ＋been＋done When I got to the theatre，I found the tickets had already been sold out. 当我到剧院时，我发现票已经卖完了。 8.将来完成时的被动语态：will/shall＋have＋been＋done By next month，all the necessary documents will have been processed. 到下个月，所有必要的文件将已处理完毕。 四、被动意义表达难点——主动语态表被动意义 1.连系动词(如look，sound，smell，feel，taste，remain，seem，hear，appear，prove 等)后接表语时，一般用主动形式表示被动意义。 The food tastes delicious. 这种食物尝起来美味可口。 What he said at the meeting sounded encouraging. 他在会上说的话听起来很鼓舞人心。 2.当 wash，write，sell，open，close，shut，lock，cook等不及物动词后加副词(easily，well等)时，通常用主动形式表示被动意义。 This kind of cloth washes easily and lasts long. 这种布料很容易洗，并且耐穿。 The pen my father gave me as a birthday gift writes smoothly. 父亲给我的作为生日礼物的钢笔写起来很流畅。 3.need，want，require，deserve等＋doing，用主动形式表示被动意义。 His hair needs cutting. →His hair needs to be cut. 他的头发需要剪了。 4.be worth doing主动形式表示被动意义。 The novel is worth reading again. 这部小说值得再读一次。 五、使用被动语态的注意事项 1.否定词not放在第一个助动词或情态动词之后。 He was extremely disappointed to hear that he would not be given a doctor’s degree. 听到不会获得博士学位，他沮丧到了极点。 2.带双宾语的动词作谓语的主动句转换为被动句时，可将表示物的(直接)宾语变为主语，用for或 to引出表示人的(间接)宾语，或将表示人的(间接)宾语变为主语。 My father is telling me an interesting story now. →An interesting story is being told to me by my father now. →I’m being told an interesting story by my father now. 我爸爸正在给我讲一个有趣的故事。 3.主动句的谓语动词带有复合宾语时，应将宾语变成被动句的主语，而将宾语补足语保留不动(这时的宾语补足语变为主语补足语)。 We saw him sitting there without doing anything. →He was seen sitting there without doing anything.我们看见他坐在那儿，什么也没做。 注意：在主动语态中，make，hear，see等词后接不定式时要省略to，但转换为被动语态时，则不能省略 to。 His words made me throw up. →I was made to throw up by his words. 他的话令我作呕。 4.短语动词在主动结构中是不可分割的，在被动结构中也是如此，不可去掉后面的介词或副词。 The old man was often laughed at. 那位老人经常被嘲笑。 5.情态动词(may，might，can，could，should，ought to，must等)后跟被动语态形式为“be done或have been done ”，其中be和have been表示被动动作的一般式和完成式，没有时态和人称变化。 Nowadays，solar energy can be used to produce electricity in many countries. 现在太阳能在许多国家可以被用来发电。 6.含有 be going to、used to、have to、had better等结构的主动句变被动句时，只需将其后的动词变为被动形式即可。 More expressways had to be built in Sichuan to promote the local economy.四川不得不建设更多的高速公路，以促进当地的经济发展。 7.不及物动词(短语)不用于被动语态，如：appear(vi.出现)、die、disappear、end (vi.结束)、fail、happen、last、lie、remain、sit、spread (vi.扩散)、stand (vi.站立)、break out、come true、fall asleep、keep silent、lose heart、take place等。 An accident happened yesterday. 昨天发生了一起事故。 8.连系动词和部分表示状态的及物动词或者动词短语无被动语态。连系动词如appear、be、become、fall、feel、get、grow、keep、look、remain、seem、smell、sound、stay、taste、turn 等；表示状态的部分及物动词如have、wish、cost；不用被动结构的常见动词短语如agree with、arrive at/in、shake hands with、succeed in、suffer from、happen to、take part in、walk into、belong to 等。 The idea sounds good.这个想法听起来很好。 The book belongs to me.这本书属于我。 1.The task ____________________ (complete)before the manager gave us further instructions yesterday. 2.The final edits ________________ (do)on the document by the editor right now. 3.The reports __________ (do)every Monday by the team before they leave the office. 4.The presentation __________ (do)by the team leader during yesterday’s meeting. 5.The house ____________________ (repair)when we toured it last month. 6.The homework _______________ (do)by the students before the class started this morning. ◎巧学活用1——单句语法填空 had been completed are being done are done was done was being repaired has been done 第二部分　非谓语动词的被动语态 一、形式与功能 非谓语动词的被动形式包括动词不定式、动词-ing形式和动词-ed形式，见下表   一般式被动 完成式被动 动词不定式的被动式 to be done(将要被……；未被……) to have been done(已经被……) 动词-ing形式的被动式 being done(正在被……；被……) having been done(已经被……) 动词-ed形式表示被动意义 只有一种形式，表示被动或者已被完成的状态 Larry persuaded her that the robot wouldn’t harm her or allow her to be harmed.拉里劝说她机器人不会伤害她，也不会让她受到伤害。 With exams being adapted into Braille，a blind senior high school student scored 630 points out of 650 in the College Entrance Examination. 试卷被改写成布拉耶盲文，一名盲人高中生在高考中获得了630分(满分650分)。 二、动词不定式的被动式 1.动词不定式的一般被动式表示其逻辑主语是动作的承受者，具有被动意义，在句中可作主语、表语、宾语、定语、状语、补语等。 The books are not allowed to be taken out of the room.不许将书带出室外。 2.动词不定式的完成被动式表示其动作先于谓语动词所表示的动作发生。 I am glad to have been invited to this party. 我很高兴被邀请参加这场聚会。 三、 动词-ing形式的被动式 1.动词-ing形式一般被动式常作主语、宾语、定语或状语，表示与其逻辑主语之间的被动关系。作定语或者状语时可表示正在被进行的动作，但作主语或宾语时只表示被动含义。 The building being repaired is our library.正在维修的那座楼是我们的图书馆。 2.动词-ing形式的完成被动式表示与其逻辑主语之间为被动关系，也表示其动作发生在谓语动词的动作之前，常作状语。 Having been shown around the library，we were taken to the lab.被带着参观了图书馆后，我们又被带去参观实验室。 四、动词-ed形式表示被动意义 1.动词-ed形式本身表示被动，用作定语、状语、补语等，和其逻辑主语形成被动关系。 The damaged car was towed away by the police. 那辆受损的汽车被警察拖走了。 The painting，created by a famous artist，is worth millions.一位著名艺术家创作的这幅画价值数百万。 2.动词-ed形式有时也可以不表示被动关系，仅表示完成的状态。 The experienced teacher handled the situation calmly.这位经验丰富的老师冷静地处理了这个情况。 She is intelligent and extremely well-read.她很聪明，而且极为博学。 1.The task seems ___________________ (do)properly，with no errors found. 2.The ___________ (complete)form should be submitted by tomorrow. 3.He

B.The rocket-like shape. C.The big bubble. D.The 3D-printed material. √ 细节理解题。根据文章第一段内容可知，工程师发明了新型的微型机器人，这项发明的优势在于尺寸小，未来可将药物送到人体里。故选A项。 2.What can we infer from Lee’s words about the robots in Paragraph 3？ A.They cure bladder diseases. B.They help to give patients pills. C.They are inspired from science fiction. D.They have performed tasks in human bodies. √ 推理判断题。根据文章第三段中的“If that sounds like something copied from science fiction，that’s because it is.”可推知，这个想法是受到科幻小说的激发。故选C项。 3.Which of the following can best replace the underlined word “biodegradable” in Paragraph 4？ A.Efficient. B.Resolvable. C.Recyclable. D.Sensitive. √ 词义猜测题。根据文章第四段中的“For a start，the group wants to make the machines fully biodegradable so that they would eventually disappear in the body，causing no damage at all.”可知，研究者希望这些机器能够消失在体内，画线词与resolvable最为接近，意为“可分解的，可溶解的”。故选B项。 4.What is the purpose of the text？ A.To introduce a healthcare robot. B.To advertise a medical machine. C.To arouse interest in developing robots. D.To raise concern about bladder diseases. √ 写作目的题。根据文章第一段内容以及下文的具体介绍可知，本文的目的是介绍一款医疗机器人。故选A项。 B (2025·辽宁省名校联盟高二下学期3月月考) When the company OpenAI developed its new artificial intelligence (AI) program，ChatGPT，in late 2022，educators began to worry.ChatGPT could create text and it seemed that a human wrote it.How could teachers discover whether students were using language created by an AI chatbot to cheat on a writing task？ As a linguist who studies the effects of technology on how people read，write and think，I believe there are other more pressing concerns besides cheating.These include whether AI，more generally，threatens student writing skills，the value of writing as a process，and the importance of seeing writing as a tool for thinking. As part of my research on the effects of AI on human writing，I surveyed young adults in the U.S.about some issues related to those effects.One participant said that at some point if you depend on predictive text，you’re going to lose your spelling abilities.Enter “Was Rom” into a Google search and you’re given a list of choices like “Was Rome built in a day”.Type “ple” into a text message and you’re offered “please” and “plenty”.These tools complete our sentences automatically，giving us little chance to think about our spelling，and continuously asking us to follow their suggestions. Evan Selinger，a philosopher，worried that predictive texting reduces the power of writing as a form of mental activity and personal expression.“By encouraging us not to think too deeply about our words，predictive technology may change how we deal with each other，” Selinger wrote，“We give others more algorithms (算法) and less of ourselves.Automation can stop us thinking and the resulting text didn’t feel like mine anymore.” I asked ChatGPT whether it was a threat to humans’ motivation to write.The bot responded：“There will always be a demand for creative，original content that requires the unique viewpoint of a human writer.” It continued：“Writing serves many purposes beyond just the creation of content，such as self-expression，communication and personal growth，which can continue to encourage people to write even if certain types of writing can be automated.” I was glad to find the program had seemingly admitted its limitations. 　　语篇解读　本文是一篇议论文。文章主要探讨了ChatGPT对学生写作的影响及其潜在问题。 5.What’s the author’s main concern about ChatGPT？ A.Whether it will lead to students’ cheating. B.Whether it will write articles like humans. C.How students will make use of it at school. D.What effects it will have on students’ writing. √ 细节理解题。根据第二段内容可知，作者更关注它对学生写作会产生什么影响。故选D。 6.What will predictive technology do to us according to Evan Selinger？ A.Give us more creative ideas. B.Make us write like a machine. C.Encourage us to think more deeply. D.Make us tend to ignore grammatical mistakes. √ 细节理解题。根据第四段内容可知，Evan Selinger认为预测性文本输入技术让表达出的自我更少，自动化会阻止我们思考，生成的文本也不再像自己写的，所以预测性技术会让我们像机器一样写作。故选B。 7.What can we learn from ChatGPT’s response？ A.Writing will become completely automated. B.Robots will work with humans in writing. C.Robot writing will become more creative. D.Human writing will still matter a lot. √ 推理判断题。根据第五段中“The bot responded：‘There will always be a demand...even if certain types of writing can be automated.’”可知，虽然未来有些写作会实现自动化，但是那些原创、个性化的写作永远是需要的。由此推知，人类完成的写作很重要，机器无法取而代之。故 选D。 8.What may the author think of the bot’s reply to his question？ A.Satisfactory. B.One-sided. C.Ambiguous. D.Unacceptable. √ 推理判断题。根据最后一段内容可知，作者对ChatGPT的回答是满意的。故选A。 Ⅱ.语法填空(每小题1.5分，共15分) (2025·辽宁省抚顺市高二下) Of the countless inventions from ancient to modern times，umbrellas are the few that 1._______________ (maintain) their shape，function and beauty so far.2.______________________ (enjoy) a history of nearly two thousand years，China’s oil-paper umbrellas number among the world’s oldest umbrellas.According to historical 3._______ (record)，the first oil-paper umbrellas in China began appearing during Eastern Han Dynasty.They soon became very popular，4.__________ (especial) among literati (文人学士) who loved to write and draw on the umbrella surfaces before applying waterproofing (防水的) oil 5.______________ (demonstrate) their artistic skill and literary tastes.6.______ wide range of elements from traditional Chinese ink painting，such as birds，flowers and landscapes，could also be found on oil-paper umbrellas as popular decorative patterns. have maintained Enjoying/Having enjoyed records especially to demonstrate A In order to spread traditional Chinese crafts，more and more young people are now getting into this industry.For example，Zhou Le from Xiangtan，Hunan Province，7.______ father instilled (逐渐灌输) in him the significance of the traditional culture of oil-paper umbrella from a young age，is breathing new life into the traditional oil-paper umbrella craft.8.__________ (motivate) by a passion for oil-paper umbrellas，he uses the power of social media and technology to spread knowledge about decorative handicrafts to the world. whose Motivated With a 9.__________ (combine) of tradition and modernity，Zhou has given many of his umbrellas poetic names and incorporated new elements such as cartoons，which young people like，into the patterns on the umbrellas，appealing 10.______ young people around the world. 　　语篇解读　本文是一篇说明文。文章介绍了中国油纸伞的历史、起源、装饰图案以及现代的发展。 combination to 1.答案：have maintained 考查动词的时态和主谓一致。空处应为谓语动词，根据时间状语so far可知，此处应使用现在完成时，主语that指代先行词the few，为复数，所以助动词用have。故填have maintained。 2.答案：Enjoying/Having enjoyed 考查非谓语动词。此处应为状语，且所给动词enjoy与主语China’s oil-paper umbrellas之间为主动关系，应用动词-ing形式，enjoy这一动作发生在谓语动词之前，所以此处也可使用动词-ing形式的完成式作状语，位于句首单词首字母需大写。故填Enjoying或Having enjoyed。 3.答案：records 考查名词复数。此处应为名词，record为可数名词，且根据上下文可知，此处应使用复数形式表示泛指意义。故填records。 4.答案： especially 考查副词。空处应为副词作状语，修饰后面整个句子。故填especially。 5.答案：to demonstrate 考查非谓语动词。根据句意可知，此处应作状语，用动词不定式形式表目的。故填to demonstrate。 6.答案： A 考查冠词。此处为短语a range of，意为“一系列的”。位于句首首字母需大写。故填A。 7.答案：whose 考查定语从句。空处引导非限制性定语从句，先行词为Zhou Le，与空后的名词father之间为所属关系，应用关系代词whose。故填whose。 8.答案： Motivated 考查非谓语动词。分析句子结构可知，动词motivate与主语he之间为被动关系，应用过去分词作状语，句首单词首字母大写。故填Motivated。 9.答案：combination 考查名词。空处位于冠词a之后，应为单数名词，动词combine的名词形式为combination。故填combination。 10.答案： to 考查介词。此处为固定短语appeal to，意为“吸引”。故填to。 返回 谢 谢 观 看 UNIT 1　SCIENCE FICTION 返回 $
