选修8 Unit 3 Inventors and inventions李仕才Ⅰ.阅读理解Two of the saddest words in the English language are “if only”. I live my life with the goal of never having to say those words, because they convey regret, lost opportunities, mistakes, and disappointment.My father is famous in our family for saying, “Take the extra minute to do it right.” I always try to live by the “extra minute” rule. When my children were young and likely to cause accidents, I always thought about what I could do to avoid an “if only ” moment, whether it was something minor like moving a cup full of hot coffee away from the edge of a computer, or something that required a little more work such as taping padding (衬垫) onto the sharp corners of a glass coffee table.I don’t only avoid those“if only” moments when it comes to safety. It’s equally important to avoid “if only” in our personal relationships. We all know people who lost a loved one and regretted that they had foregone an opportunity to say “I love you” or “I forgive you”. When my father announced he was going to the eye doctor across from my office on Good Friday, I told him that it was a holiday for my company and I wouldn’t be there. But then I thought about the fact that he’s 84 years old and I realized that I shouldn’t give up an opportunity to see him. I called him and told him I had decided to go to work on my day off after all.I know there will still be occasions when I have to say “if only” about something, but my life is definitely better because of my policy of doing everything possible to avoid that eventuality(可能发生的事). And even though it takes an extra minute to do something right, or it occasionally takes an hour or two in my busy schedule to make a personal connection, I know that I’m doing the right thing. I’m buying myself peace of mind and that’s the best kind of insurance for my emotional well-being.1.Which of the following is an example of the “extra minute” rule ?A. Start the car the moment everyone is seated.B. Leave the room for a minute with the iron working.C. Wait for an extra minute so that the steak tastes better.D. Move an object out of the way before it trips someone.2.The author decided to go to her office on Good Friday to __________.A. keep her appointment with the eye doctorB. meet her father who was already an old manC. join in the holiday celebration of the companyD. finish her work before the deadline approaching3.The underlined word “foregone” in Paragraph 3 is closed in meaning to “_________”.A. abandonedB. lackedC. avoidedD. wasted4.What is the best title for the passage ?A. The Emotional Well-beingB. The Two Saddest WordsC. The Most Useful RuleD. The Peace of Mind【文章大意】这篇文章主要讲解的是作者对于最悲哀的两个单词if only 的理解及看法。

2019届高考英语(人教版)一轮复习练习：选修8 3 Unit 3 知能演练轻松闯关 Word版含答案

Ⅰ阅读理解A(2018·湖北部分重点中学联考)Jon Hoffman was sitting at a red light when he saw a man run out of a store carrying a plastic donation jar full of cash.Dressed in plain clothes，Jon Hoffman caught the man and pressed him against the hood(引擎盖) of his car. But Hoffman had trouble controlling the thief，and they got into a struggle.“The detective has a military background，and he said he thought the suspect must have a military background，too，because he was able to break away so easily，” a local police spokesperson said.The detective called out for help as a crowd gathered. Among those watching were Harvey and Kirby，two day laborers.Harvey did what has become common these days—he took out his phone to shoot the video. “I hate to say it，but I thought that this policeman was doing something stupid，”Harvey said. “But when he asked for help，I thought，well，there wouldn’t be shooting if I got over there in time.”Harvey jumped into action，while he was still recording the video. So did Kirby.“Harvey caught hold of the suspect’s arms，while Kirby seized his legs，and they were able to get the suspect to the ground to help Detective Hoffman put the handcuffs(手铐) on，”said the police spokesperson. The 27-year-old suspect was charged with resisting arrest and other offenses. The charity jar he stole held less than$50.“I’ve been on the wrong side of the law several times in my life，”Harvey said. “It feels good to be on the right side and do something positive.”After the arrest，the three men got to know each other at a local steak house—Hoffman’s treat，as a thank you.【解题导语】本文是一篇新闻故事，讲述了一位侦探在两位临时工的协助下制服一名嫌疑人的过程.1.What made Hoffman call for help when arresting the suspect?A.He was not on duty.B.He couldn’t control the suspect.C.He needed witnesses to support him.D.He wanted to push the thief into the car.B解析：细节理解题.根据第一段的最后一句可知，Hoffman控制住那个嫌疑人有困难，并且他们扭打在一起.故选项B正确.2.What can be inferred about Harvey?A.He was ready to break the law.B.He was out of work at that time.C.He had a good military background.D.He might have had some illegal deeds.D解析：推理判断题.根据第六段中的“I’ve been on the wrong side of the law severaltimes in my life”可知，Harvey曾经违反过法律，所以选项D “他可能有过一些违法行为”是正确的.3.What is Hoffman’s attitude towards Harvey and Kirby?A.Grateful.B.Prejudiced.C.Skeptical.D.Admirable.A解析：推理判断题.根据最后一段中的“Hoffman’s treat，as a thank you”可知，嫌疑人被捕后，Hoffman请Harvey和Kirby吃饭，作为对他们的感谢.所以选项A正确.B(2018·济南模拟)A European Union program is letting blind peopleexperience famous paintings for the first time. It uses three－dimensional(3－D) printing to recreate famous paintings so they can betouched.One painting printed with the new technology is Gustav Klimt’s“TheKiss”.It is a popular attraction at the Belvedere Museum in Vienna,Austria. The painting shows a man and a woman standing in a field filled with flowers. They are wearing gold robes and have their arms around each other. The man leans down to kiss the woman.Klimt finished the painting in 1908. Until now, people who had trouble seeing could not appreciate the artwork. But thanks to the reproduction they can touch the piece and feel the ridges and depressions. Andreas Reichinger started making 3－D versions of artwork in 2010. He said this reproduction was his most difficult project because the couple’s robes are so detailed.Dominika Raditsch is a blind museum visitor. She touched the reproduction. As she moved her hands around it she said, “Exactly, can you see these? There are so many details.”Raditsch said she could imagine what the original painting looks like when she touched the reproduction. “It’s somehow round. You can feel it. You can feel it. It comes with it. And in many places it’s so smooth. And then I think to myself: it probably shines too！”Raditsch said.The Belvedere is not the only museum to have 3－D versions of its artwork. Some of the pieces at the Prado Museum, in Madrid, Spain have reproductions that can be touched. But the piece in Vienna has one special part: it is made with widely available 3－D printing technology. That means one day, blind art fans anywhere in the world could download the source files and print the reproductions themselves.【解题导语】本文是一篇说明文.文章讲述了欧盟的一个项目使用3D打印技术重现名画，让它们可以被视障人士触摸到.4.What is “The Kiss”？A.A European Union project.B.A popular painting.C.A 3－D technology.D.A famous museum.B解析：细节理解题.根据第二段中的“One painting printed with the new technology is Gustav Klimt’s ‘The Kiss’. It is a popular attraction...”可知，《吻》是一幅深受大家欢迎的画作.故选B项.5.Why did Reichinger say this reproduction was difficult to finish?A.The painting was reproduced detailedly.B.The original artwork was made in 1908.C.Blind art fans can’t download the source.D.The 3－D technology is not available.A解析：细节理解题.根据第三段中的最后一句可知，Andreas Reichinger说《吻》是最难完成的作品，因为那对恋人的长袍细节很多.故选A项.6.How did Raditsch feel when she first touched the reproduction?A.Awkward.B.Puzzled.C.Excited.D.Nervous.C解析：推理判断题.根据第四段中的“You can feel it. You can feel it.”可以推测出Raditsch“激动的”心情.故选C项.7.What is the best title for the text?A.A European Union Program for Museum VisitorsB.3－D Printing Lets the Blind Experience Famous PaintingsC.How to Reproduce the World－famous PaintingsD.A Special Museum for Art Fans in Vienna, AustriaB解析：标题归纳题.根据第一段中的内容可以看出，用3D打印技术让视障人士体验名画是文章的中心，下文是围绕该话题展开介绍的.故选B项.Ⅱ完形填空(2018·西宁检测)Many students often say that they don’t have “eno ugh time” to do all their schoolwork. My __1__is often brief, “You have as much time as the president.”I usually carry on a bit about __2__twenty four hours in the day for everyone, and suggest that “not enough time”is not a(n)__3__explanation of __4__something done.__5__in graduate school, I tried to prove to one of my professors __6__saying that I was working hard. His answer to me was, “That’s irrelevant. __7__is important is the __8__of your work.”Since then I have had time to think carefully about the trick of “__9__”，and I have come to some __10__all relevant to the problem of how much time we have.If you analyze the matter, you can identify two parts of the problem: There is, __11__，the matter of “time”，which we can think of __12__. Then there is the problem of “work” during that time. But, as my professor suggested, it’s not how hard one works __13__the quality of theproduct that’s important.That led me to a new idea: the quality of the work. That __14__is perhaps best explained by a sign I once saw on the wall in someone’s office：“Don’t work harder.__15__.”There is a lot of sense in that idea.If you can’t get more time, and few of us can, the only solution is to improve the quality of the work. That means thinking of ways to get more out of __16__time than we might otherwise get. That should lead us to an analysis of our work habits. Since “work”for students usually means“homework”，the expression “work habits”should be read as “__17__ habits”.Then, as a smart student, you will __18__those skills that you use in study，__19__reading and writing. If you learn to read better and write better, there are big benefits that __20__in all your studies.【解题导语】本文是一篇议论文，主要论述了“工作和学习不要总是强调更勤奋，而应当强调更聪明”这一观点，指出应当提高自己的工作质量和工作效率，而不是一味强调“勤奋”.1.A.question B.ideaC.replyD.keyC解析：根据该句中的“You have as much time as the president.”可知，该处回答了上文的疑问；C项意为“回答”，故C项正确.A项意为“问题”，B项意为“想法”，D项意为“关键，答案”，都与语境不符.2.A.there being B.there areC.there beD.there to beA解析：根据该句中的“twenty four hours in the day for everyone”可知，每个人每天都有24小时，故用“there be”结构，表示“存在，有”，介词about后跟名词、代词、动名词作宾语，故A项正确.3.A.strange B.acceptableC.surprisingD.demandingB解析：根据语境可知，每个人每天都有24小时，所以“没有足够的时间”作为解释是不能接受的；B项意为“可接受的”，故B项正确.A项意为“奇怪的”；C项意为“令人惊讶的”；D项意为“要求高的，费力的”.4.A.no getting B.not gettingC.no lettingD.not lettingB解析：根据语境可知，每个人每天都有24小时，所以“没有足够的时间”不能解释没有完成工作.get something done 为固定搭配，意为“完成某事”，该处表示否定，前面用not，故B项正确.5.A.Since then B.Just nowC.EverD.OnceD解析：根据该句中的“I tried to prove to one of my professors”，结合下文的“His answer to me was”可知，该处叙述的是一件过去发生的事情，D项意为“曾经”，故D项正确.A项意为“从那时起”；B项意为“刚刚，刚才”；C项意为“曾经”.6.A.by B.inC.onD.uponA解析：根据该句中的“saying that I was working hard”可知，“我”试图通过说“我”自己工作勤奋来向“我”的一位教授证明自己；A项表示方式，故A项正确.7.A.That B.WhatC.WhetherD.IfB解析：分析该句结构可知，空处引导主语从句，也作该从句的主语，故用连接代词what；该句意“重要的是你的工作质量”，故B项正确.8.A.quantity B.amountC.numberD.qualityD解析：根据上文中的“I was working hard”，结合该句语境和第三段最后一句中的“quality”可知，教授对“工作勤奋”的回答是“重要的是工作质量”；D项意为“质量”，故D项正确.A项意为“数量”；B项意为“数量”；C项意为“数字”.9.A.hard worker B.honest studentC.busy presidentD.future graduateA解析：根据该段第一句中的“I was working hard”，结合空前一句教授对此的回应可知，从那时起“我”就开始仔细思考“勤奋工作者”的技巧；A项和“working hard”匹配，故A项正确.B项意为“诚实的学生”；C项意为“忙碌的总统”；D项意为“未来的毕业生”.10.A.constructions B.contributionsC.conclusionsD.concentrationsC解析：根据该句中的“I have come to”，结合下文内容可知，就此问题，“我”已经得出结论.C项意为“结论”，故C项正确.A项意为“建筑”；B项意为“贡献”；D项意为“集中”.11.A.of course B.in factC.as a resultD.as a wholeA解析：根据语境并结合常识可知，这一问题中最重要的当然是时间；A项意为“当然”，故A项正确.B项意为“事实上，实际上”；C项意为“结果是……”；D项意为“作为整体”.12.A.if followed B.if fixedC.as followedD.as fixedD解析：根据空后一句“Then there is the problem of ‘work’during that time.”可知，接下来是在此期间的“工作”问题；据此可以判断，该处是说，人们总是认为时间是固定不变的，故D项正确.13.A.so B.butC.norD.andB解析：根据该句中的“it’s not how hard one works ______the quality of the product that’s important”可知，并不是工作多么勤奋，而是产品的质量才是重要的；not...but...为固定搭配，意为“不是……而是……”.14.A.concept B.senseC.explanationD.solutionA解析：根据上文中的“a new idea”可知，该处指这种新观念(concept)，故A项正确.B 项意为“感觉”；C项意为“解释”；D项意为“解决办法”.15.A.Work more smartly B.Work fasterC.Think twiceD.Think aloudA解析：根据上文中的“Don’t work harder.”可知，工作不要更努力；据此可以判断，空处与此对应，意为“工作要更聪明”，故A项正确.B项意为“工作更快”；C项意为“三思而行”；D项意为“自言自语”.16.A.a little B.the moreC.the lessD.the sameD解析：根据语境可知，更聪明地工作意味着在同一时间内想出能得到更多的方法，故D项正确.17.A.living B.studyC.thinkingD.sleepingB解析：根据该句中的“Since ‘work’ for students usually means ‘homework’，the expression ‘work habits’should be read as”可知，对于学生来说，工作即是家庭作业，故“工作习惯”即为“学习习惯”，B项意为“学习”，故B项正确.A项意为“生活”；C 项意为“思考”；D项意为“睡眠”.18.A.seek improving B.seek to improveC.find improvingD.find to improveB解析：根据语境并结合常识可知，作为一个聪明的学生，你要寻求高效学习的技能，故用seek to improve，故B项正确.19.A.chiefly B.brieflyC.actuallyD.occasionallyA解析：根据下文中的“If you learn to read better and write better”并结合常识可知，该处指学生主要在阅读和写作上提高自己；A项意为“主要地”，故A项正确.B项意为“暂时地，简要地”；C项意为“事实上”；D项意为“偶尔，间或”.20.A.are paid B.is paidC.pays offD.pay offD解析：根据语境可知，如果你学会更好地写作和阅读，则你的所有学习将取得巨大的回报.D项意为“成功，奏效”，故D项正确.。

课时规范练38(选修8Unit 3)Ⅰ.阅读理解A(2018·山东平阴第一中学第三次月考)It’s up there right now,flying about 340 miles above the earth.It’s a telescope in the sky.It’s called the Hubble Space Telescope.The telescope itself is not really much to look at.If you could see it right now,you might think it’s just a big bucket with two solar arms.It’s about the size of a school bus and weighs about as much as two elephants.But that silver bucket is pure gold for astronomers.It has made such a big impact that NASA,the space agency that takes amazing pictures,calls Hubble the most important advance in astronomy since Galileo’s telescope.Hubble didn’t win high marks in the beginning.It was launched on April 24,1990,aboard the space shuttle Discovery from Kennedy SpaceCenter,Florida.The next day it was released into space,but scientists soon realized there was a big problem.The telescope’s primary mirror had a flaw (瑕疵).Hubble became a late-night talk show joke.But in December of 1993 shuttle Endeavour astronauts repaired the telescope.The late-night joke stopped.So why is Hubble so special?Because it’s on what NASA calls the ultimate mountaintop.Sitting high above the earth,far away from our light-polluted cities and hovering (盘旋) far away from clouds and storms,Hubble has a good view of the universe.Scientists have used it to make observations about planets,stars,galaxies and to show parts of our universe we didn’t know.The telescope has made more than 1 million observations and astronomers have used Hubble data in more than 12,700 scientific papers,making it one of the most productive scientific instruments ever built.Eventually,Hubble will stop working.NASA hopes to use a space shuttle to bring it home for a museum exhibit.Now,it seems that NASA will have to come up with a plan to help its superstartelescope come back to the earth and fall into the sea.Hubble fans hope that date is far in the future,but NASA already has plans to send up a new space-based instrument,the James Webb Space Telescope,in 2018.1.What does the Hubble Space Telescope look like?A.A school bus.B.A heavy elephant.C.A bucket.D.A long arm.2.Why did the Hubble Space Telescope become a late-night joke?A.It had a flaw in its primary mirror.B.It was launched in Florida.C.It appeared on a talk show.D.It took the amazing pictures.3.What do the scientists think of the Hubble Space Telescope?A.Effective and useful.B.Special and strange.C.Ancient and helpless.D.Interesting and funny.4.Where will the Hubble Space Telescope stay in the end?A.In the sea.B.In a museum.C.In outer space.D.On the mountaintop.〚导学号23280151〛B(2018·福建福州八县一中第二次月考)Three Chilean students got the idea for a plant-powered device to charge their cellphones,while sitting in their school’s outdoor courtyard during a break from exams,with dead mobile phones.Then,one of them had an “aha” moment.“It occurred to Camila to say about plants,” said inventor Evelyn Aravena.“There are so many plants and living things that have the potential to produce energy;why don’t they have a charging outlet?”Their invention —a small biological circuit (生物电路板) called E-Kaia—takes advantage of the energy plants produce during photosynthesis (光合作用).A plant uses only a small amount of that energy—the rest goes into the soil,and that’s where the E-Kaia collects it.The device literally plugs into the ground and then into your phone.“They brought the prototype;the prototype worked—and that’s when it all changed.It’s the most amazing project I’ve ever seen in my life,plain and simple,but it was transformational.And I began to support them,” said Mauricio Cifuent es of Duoc University.The device solved two problems for the engineering students—they needed an idea for a class project and an outlet to plug in their phones.“Looking for a place to charge the mobile phones and the notebook that had no energy,we weren’t able to find anything because all the other students were in the same state of madness trying to find a place to charge their devices,” said Aravena.But plants are everywhere,and the biological circuit uses their excess power.“There is a complete energy cycle of the plant.We decided to incorporate into the cycle,and then we would not affect the plant’s growth.The biological circuit makes an acquisition and that is transformed into energy to later make charges for low consumption,” said inventor Camila Ru pcich.The E-Kaia doesn’t carry much charge,but it’s powerful enough to completely recharge a mobile phone in less than two hours.The student inventors have applied for patent on their technology,and expect the E-Kaia to go on sale in December.5.According to the text,the E-Kaia .A.should be put into a mobile phoneB.may slightly affect the plant’s growthC.collects the energy plants produce from the soilD.consumes several hours to charge a mobile phone6.The underlined word “prototype” in Para.4 can be replaced by “”.A.original modelB.outdoor plantC.mobile phoneD.key concept7.The invention of the plant-powered device shows that.A.good things require timeB.wisdom is better than strengthC.necessity is the mother of inventionD.God helps those who help themselves8.What is the main idea of the text?A.Photosynthesis brings plants energy.B.There are efficient ways to charge phones.C.The energy cycle of the plant is quite powerful.D.Chilean students find a green way to charge phones.〚导学号23280152〛Ⅱ.七选五阅读Secret codes (密码)keep messages private.Banks,companies,and government agencies use secret codes in doing business,especially when information is sent by computer.People have used secret codes for thousands of years.1 Code breaking never lags (落后) far behind code making.The science of creating and reading coded messages is called cryptography.There are three main types of cryptography.2For example,the first letters of “My elephant eats too many eels” spell out the hidden message “Meet me.”3 You might represent each letter with a number,for example.Let’s number the letters of the alphabet,in order,from 1 to 26.If we substitute a number for each letter,the message “Meet me” would read “13 5 5 20 13 5.”A code uses symbols to replace words,phrases,or sentences.To read the message of a real code,you must have a code book.4For example,“bridge” might stand for “meet” and “out” might stand for “me.” The message “Bridge out” would actually mean “Meet me.” 5 However,it is also hard to keep a code book secret for long.So codes must be changed frequently.A.It is very hard to break a code without the code book.B.In any

There are two types of people in the world.Although they have equal degree of health and wealth and other comforts of life,one becomes happy and the other becomes unhappy.This arises from the different ways in which they consider things,persons,events and the resulting effects upon their minds.People who are to be happy fix their attention on the convenience of things: the pleasant parts of conversation,the well prepared dishes,the goodness of the wine and the fine weather.They enjoy all the cheerful things.Those who are to be unhappy think and speak only of the opposite things.Therefore,they are continually dissatisfied.By their remarks,they sour the pleasure of society,offend(hurt) many people,and make themselves disagreeable everywhere.If this turn of mind was founded in nature,such unhappy persons would be the more to be pitied.The intention of criticizing(批评) and being disliked is perhaps taken up by imitation(模仿).It grows into a habit,unknown to its possessors.The habit may be strong,but it may be cured when those who have realized its bad effects on their interests and tastes.I hope this little warning may be of service to them,and help them change this habit.Although in fact it is chiefly an act of the imagination,it has serious results in life since it brings on deep sorrow and bad luck.Those people offend many others; nobody loves them,and no one treats them with more than the most common politeness and respect.This frequently puts them in bad temper and draws them into arguments.If they aim at getting some advantages in social position or fortune,nobody wishes them success.Nor will anyone start a step or speak a word to favor their hopes.If they bring on themselves public objections,no one will defend or excuse them,and many will join to criticize their wrongdoings.These should change this bad habit and be pleased with what is pleasing,without worrying needlessly about themselves and others.If they do not,it will be good for others to avoid any contact(接触) with them.Otherwise,it can be disagreeable and sometimes very inconvenient,especially when one becomes mixed up in their quarrels.1.People who are unhappy_____.A.always consider things differently from othersually are affected by the results of certain thingsually misunderstand what others think or sayD.always discover the unpleasant side of certain things2.The phrase “sour the pleasure of society” means “_____ ”.A.have a good taste with social lifeB.make others unhappyC.tend to scold others openlyD.enjoy the pleasure of life3.In this passage,the writer mainly____.A.describes two types of peopleughs at the unhappy peopleC.suggests the unhappy people should get rid of the habits of unhappinessD.tells people how to be happy in life参考答案：1.D; 2.B; 3.C解析：生活中有些人拥有相同的健康、财富和生活条件,但由于考虑事情、人物、事件的角度不同,一些人感到幸福,而另一些人则感到不幸福。

The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.“It's extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件)，”said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago，his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own，” he said.They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it's connected to.”said Wood. The flight device was built into a set of power，computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers' fields or on the battlefield. “Basically it should be able to take off, land and fly around，” he said.Wood says the design offers a new way to study flight mechanics and control insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications.“You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robotsinstead，” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drive us on a d ay to day basis.”[语篇解读]本文主要讲述哈佛大学从自然界的昆虫那里得到了灵感，设计开发了第一款机器苍蝇。
