2020版高考英语(人教)新探究大一轮复习练习：选修8 Unit 3 课后达标检测 (附答案解析)
(建议用时：30分钟)Ⅰ阅读理解A(2019·辽宁五校协作体联考)In the dead of winter，we don’ttypically think about spending time outdoors，but according to manyphysicians we should．The sun is our greatest source of a vitamin that isessential for good health—Vitamin D.This important vitamin strengthens bones and teeth and is linked to the prevention of heart disease，cancer and many other lifethreatening diseases．The recommended daily requirement is 400－600 International Units (IU). In summer, people with dark brown eyes and darker skin turn sunlight from just 15 minutes outside without sunscreen into adequate amounts of Vitamin D.Even during winter, just a 10minute walk at midday can keep the body’s Vitamin D at healthy levels．During brief winter walks，we receive the greatest benefits when we wear no sunscreen and expose as much skin to the sun as possible.Vitamin D can be also obtained from foods．Salmon is one of the best sources of the Vitamin. Egg yolks(蛋黄)，cheese，mushrooms and some animal organs contain smaller quantities of it.To attract consumers，food companies add Vitamin D to some of their milk products．The practice of putting the Vitamin into milk began in the 1930s．At that time，many children were suffering from rickets，an illness that is caused by a deficiency(缺乏)of Vitamin D．It made the children’s bones soft and weak．Adding Vitamin D to milk helped to solve the problem, and it has been available ever since.For people who still need more Vitamin D, there is another option. Take Vitamin D supplements(补充物)．These products are widely sold in stores．However，anyone considering taking supplements should consult a physician first.【解题导语】本文是一篇科普文。

B(2019·成都重点中学高三段考)Amazing concept images have shown what homes of the future could look like, as preparations are made for the world’s first freeform 3Dprinted property(房产).Experts will build a house called Curve Appeal, which will be 3Dprinted offsite before being put together on-site to create two outside walls, a roof and an inside part．These four main sections will then be joined together.Although 3Dprinted buildings have been made before, this home—to be constructed in Chattanooga, Tennessee, later this year—will be the first of its kind, as it will contain no regular shapes or angles．The house is the creation of the design company WATG, based in London and California．The design for Curve Appeal draws inspiration from the Case Study House program.The architects leading the program were famed for constantly pushing the limits in terms of minimalist(极简抽象派的) materials, and trying to create openplan spaces that focused on enhancing natural light．In a written statement, a spokesman for W ATG said, “Employing many of the same modern design principles, Curve Appeal is the next evolutionary step．It’s important that the architecture and the environment work together harmoniously．The chosen site is steps away from the Tennessee River in a beautiful wooded, sunlit area．”WATG was awarded the first prize in the Freeform Home Design Challenge in 2016 and given prize money of $8, 000 to make its plans a reality．The competition was aimed at architects, designers, engineers and artists．Participants were challenged to design a 600 to 800-sq ft single-family home that rethinks traditional aesthetics(美学), ergonomics, construction, building systems and structure.Over the last year, WATG’s Chicago office has been developing their design with BranchTechnology．This project is currently underway, working towards breaking ground later this year．Once completed, the Curve Appeal home will have open and lightfilled inside living spaces.【解题导语】本文是一篇说明文，主要介绍了3D打印的名为Curve Appeal的极简抽象派房屋的相关情况。

Technology companies and experts from around the world come to the event to see, hear and talk about the latest ideas and inventions. Each year's show has special trends.Ultra HDTVs (超高清电视)One trend at this year's show is the Ultra HDTV. Its picture is much better than that of the regular HDTV. The electronics maker Samsung says it will make more developed Ultra HDTVs. And Sony says all of its televisions will use the Android system.Internet-connected devicesAnother trend at the show is the practice of connecting home devices to the Internet. People can now connect dishwashers, stoves and refrigerators to the Internet. However, developers still want to invent a way for all of the devices to be able to communicate with each other.Wearable devicesOne such device is a special helmet (头盔) that uses light to grow hair on a person's head. Another device helps reduce pain that people may have had for a long time. Developers also showed a ring that can be used to control other devices using hand movements.3-D devicesThere has been a large growth in the number of 3-D printers produced in the past year. Because of this increase, prices are much lower—several models cost less than $1,000. In addition to 3-D printers, there is now a new 3-D pen. It lets users draw 3-D objects.Newly-developed robotsRobots are also shown at this year's show. Some of them help children learn computer programming.【解题导语】本文是一篇应用文。

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。

get in“插话，收割”；get away“离开；走开”；get off“下车”；get through“接通电话，完成，到达，通过”，由此可知该题的答案为D项，意思是“你打通电话了吗？”答案 D2．So far nobody has claimed the money______in the library.A．discovered B．to be discoveredC．discovering D．having discovered解析考查非谓语动词作定语。
句意：迄今为止，没有人认领在图书馆里发现的钱。
因discover与money之间是逻辑上的动宾关系，故用过去分词作定语。
答案 A3．There were many talented actors out there just waiting______.A．to discover B．to be discoveredC．discovered D．being discovered解析考查不定式的被动式作目的状语。
解答这类题时，一定要弄清非谓语动词和主语之间的逻辑关系。
句意：在外面有许多有才华的演员等着被发现。
to be discovered 为不定式短语作目的状语。
discover与其逻辑主语actors之间为动宾关系，且discover 动作是将要发生，故用动词不定式的被动式。
答案 B4．After that，he knew he could______any emergency by doing what he could to the best of his ability.A．get away with B．get on withC．get through D．get across解析考查get动词短语。

阅读提速练Ⅰ阅读理解A(2019·湖北八校第一次联考)Leaders shape history and here is aselection of the most remarkable views into these public figures plusfirst-hand accounts by those with access to them.Margaret Thatcher by Charles Moore (2013)Before Moore published the first volume of his biography, there had already been a mountain of books on Thatcher．Moore’s account is different. He shows that far from being fearless, she could often be fearful without cause．The final volume will include her fall from power.Harold Wilson by Ben Pimlott (1992)Harold Wilson had become a ghostly figure when this book was published in 1992．The absence heightened a sense of mystery．Who was he? How to explain his seemingly contradictory characteristics? Pimlott solves some of the mysteries; the book is detailed until Wilson’s final phase as prime minister in 1974.Churchill by Roy Jenkins (2001)Jenkins writes as a politician as well as a historian, analyzi ng Churchill’s historic moves from the opinions of one who had also spoken in the Commons．Jenkins had resigned from high positions in battles over policy, and as one that changed parties, though not as frequently as Churchill did.Roy Jenkins by John Campbell (2014)Campbell calmly narrates many political and personal dramas, including Jenkins’intense relationship with Anthony Crosland when they were both students at Oxford．Campbell also addresses Jenkins’various affairs with women．Like Jenkins’ political heroes, he led many lives. Campbell is sharp in describing each of them.Diaries, Volumes One to Six by Alastair Campbell (2017)Love or hate him, Campbell remains the master of the inside story, not just because of his unusual ideas on the relationship between Tony Blair and Gordon Brown．This is an incredibly detailed book on what it’s like to live inside No．10: the cruel space of events; and the constant conflict with the media.【解题导语】本文是一篇应用文。

考点规范练38(选修8Unit3)Ⅰ.阅读理解A(2017·全国Ⅰ)A build-it-yourself solar still(蒸馏器) is one of the best ways to obtain drinking water in areas where the liquid is not readily available.Developed by two doctors in the U.S.Department of Agriculture,it’s an excellent water collector.Unfortunately,you must carry the necessary equipment with you,since it’s all but impossible to find natural substitutes.The only components required,though,are a 5'×5' sheet of clear or slightly milky plastic,six feet of plastic tube,and a container—perhaps just a drinking cup—to catch the water.These pieces can be folded into a neat little pack and fastened on your belt.To construct a working still,use a sharp stick or rock to dig a hole four feet across and three feet deep.Try to make the hole in a damp area to increase the water catcher’s productivity.Place your cup in the deepest part of the hole.Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up—and out—the side of the hole.Next,cover the hole with the plastic sheet,securing the edges of the plastic with dirt and weighting the sheet’s center down with a rock.The plastic should now form a cone(圆锥体) with 45-degree-angled sides.The low point of the sheet must be centered directly over,and no more than three inches above,the cup.The solar still works by creating a greenhouse under the plastic.Ground water evaporates (蒸发) and collects on the sheet until small drops of water form,run down the material,and fall off into the cup.When the container is full,you can suck the refreshment out through the tube,and won’t have to break down the still every time you need a drink.1.What do we know about the solar still equipment from the first paragraph?A.It’s delicate.B.It’s expensive.C.It’s complex.D.It’s portable.2.What does the underlined phrase “the water catcher” in paragraph 2 refer to?A.The tube.B.The still.C.The hole.D.The cup.3.What is the last step of constructing a working solar still?A.Dig a hole of a certain size.B.Put the cup in place.C.Weight the sheet’s center down.D.Cover the hole with the plastic sheet.4.When a solar still works,drops of water come into the cup from.A.the plastic tubeB.outside the holeC.the open airD.beneath the sheetBBrooke Martin’s golden retriever(金毛猎犬)Kayla hated being left alone or separated.She would howl,pace,and chew on things.Brooke learned that other people had the same problem with their pets.She wondered:“What if you could talk to your dog if you were gone?”Working with her father in their garage,the 16-year-old came up with several ideas.Finally,she invented a device that allowed pet owners to video chat with their pets!She calls the device iCPooch.“The dog doesn’t have to answer the call,”explains Brooke.“It comes up immediately on the screen on its end.It’s a two-way audio and video—you can see and hear each other.”With a click of a button you can even send the dog a treat!Her invention has earned her a spot competing against nine other finalists in a young scientist competition for middle-school students.These finalists,selected based on their short video presentations,are working with mentors over the summer before heading to the final competition in St.Paul,Minn.After Martin’s video put her among the 10 finalists in the Discovery Education 3M Young Scientist Challenge,she was paired with Delony Langer-Anderson,a product development scientist in 3M’s consumer health care division.“I just lead her down the product development path,”Langer-Anderson told LiveScience.This path includes guidance on how to test the potential product,which combines a video chatdevice that answers immediately on the dog’s end with a dog treat device the owner can remotely activate.“One thing I have thought about a lot is,what happens if while the device is on the floor,what if your dog knocks it over,or scratches the screen?”Martin said.She and Langer-Anderson discussed this,and Martin is now testing materials at a local dog shelter by taping them to the dog house floor to see how well they withstand sharp teeth and claws.The finalists create models they can test,with the guidance from a mentor.Their projects include a fuel cell that transforms cut grass into electricity and an app that rewards drivers for not texting ornger-Anderson tries to help the students work through the scientific method,testing their hypothesis,in a determined way.“So the kids don’t get buried in data,”she said.5.Which of the following would be the best title of the text?A.“iCPooch” wins in a young scientist competitionB.A 16-year-old girl invents a device for dogs’ hungerC.A man-made device lets people chat with their petsD.A kid-invented device calms dogs’ separation anxiety6.“iCPooch” calms pet dogs by .A.allowing video chatB.making dogs sleepC.answering the callD.giving them food7.What is the probable meaning of the underlined word “mentors”?petitors.B.Assistants.C.Instructors.panions.8.What do the inventions of the finalists have in common?A.They are all new inventions dealing with pets.B.They are possible solutions to everyday problems.C.They cope with the problems related to computers.D.They are all accomplished through individual work.Ⅱ.七选五阅读How to Get on a Reality TV ShowThink carefully before you leap!Being on a reality TV show is about being exposed.And that exposure is to everyone,including your family,friends,neighbors,and your former school teachers.Is this something you can handle?1 If you’re not worried about this,then you’re ready!On the other hand,if you value your privacy and reputation intensely,reality TV stardom may not be for you.Give it up before things get difficult if that’s the case!2For a brand-new show,read whatever is already available in the media about the show’s intended themes,content,time slot,and audience.3 This is probably easier if you’ve watched it without fail since it began.Be practical.When you assess your suitability to go any further,some of the things that you should keep in mind include being realistic.It makes little sense to apply to be in a weight loss show whenyou’re already at an ideal weight.4 If you’re applying for a show wanting people with a business background or a college education and you don’t have one,again,it may not be worth your while.Know why you want to do this.The show’s producers will want a strong,well-founded response.5 Telling them “I want to be famous”rarely distinguishes you from every other person wanting the same.Be confident in what you believe you can contribute to the show while focusing on your hoped-for outcome.A.Can you actually sing,dance,act,etc.,as required?B.Learn all that you can about the show before applying.C.Do you mind if people who used to know you talk about you?D.Nor is it wise to try modeling when your height isn’t what they’re looking for.E.Do you have to eat things that are simply awful and that you’d never think of eating in a million years?F.Give an answer that shows your strengths,your interesting points,and a desire to be a good role model.G.For an existing show,it makes good sense to be up-to-date about the entire show from its previous seasons.Ⅲ.短文改错I once took part in a speech contest.Such difficult was the topic that I completely had no idea about it.Even a time for preparation was so limited.I felt hopeful and wanted to give up.And deep in my heart Ididn’t want to be a failure.So I recovered my courage and take the contest seriously.I kept remind myself,“If I try my best,I won’t feel regretful,whichever the result is.”In the following days I struggled my goal.At the end,all my efforts paid off.I won first prize,which was much better than what I had expected it.考点规范练38(选修8Unit3)Ⅰ.【解题导语】美国农业部的两位博士研制出一种蒸馏器。
