2013年6月15日英语四级(CET-4)真题及答案
Part II (15 minutes) 1、回答1-11题: Can Digital Textbook Truly Replace the Print Kind? The shortcomings of traditional print edition textbooks are obvious: Forstarters they're heavy, with the average physics textbook weighing 3.6 pounds.They're also expensive, especially when you factor in the average collegestudent's limited budget, typically costing hundreds of dollars every semester. But the worst part is that print version of textbooks are constantlyundergoing revisions. Many professors require that their students use only thelatest versions in the classroom, essentially rendering older texts unusable.For students, it means they're basically stuck with a four pound paper-weightthat they can't sell back. Which is why digital textbooks, if they live up to their promise, couldhelp ease many of these shortcomings. But till now, they've been something likea mirage (幻影) in the distance,more like a hazy (模糊的) dream thanan actual reality. Imagine the promise: Carrying all your textbooks in a 1.3pound iPad? It sounds almost too good to be true. But there are a few pilot schools already making the transition (过度) over to digital books. Universities like Cornell and Brown havejumped onboard. And one medical program at the University of California,Irvine, gave their entire class iPads with which to download textbooks justlast year. But not all were eager to jump aboard. "People were tired of using the iPad textbook besides using it forreading," says Kalpit Shah, who will be going into his second year atlrvine's medical program this fall. "They weren't using it as a source ofcommunication because they couldn't read or write in it. So a third of thepeople in my program were using the iPad in class to take notes, the otherthird were using laptops and the last third were using paper and pencil." The reason it hasn't caught on yet, he tells me, is that thefunctionality of e-edition textbooks is incredibly limited, and some studentsjust aren't motivated to learn new study behavior. But a new application called Inkling might change all that. The companyjust released an updated version last week, and it'll be utilized in over 50undergraduate and graduate classrooms this coming school year. Digital textbooks are not going to catch on," says Inkling CEO MattMaclnnis as he's giving me a demo (演⽰) over coffee. "What I mean by that is the current perspectiveof the digital textbook is it's an exact copy of the print book. There's CourseSmart, etc., these guys who take any image of the page and put it on a screen.If that's how we're defining digital textbooks, there's no hope of that becominga mainstream product." He calls Inkling a platform for publishers to build rich multimediacontent from the ground up, with a heavy emphasis on real-world functionality.The traditional textbook merely serves as a skeleton. At first glance Inkling is an impressive experience. After swiping (敲击) into the iPad app (软件), which youcan get for free here, he opens up a few different types of textbooks. Up first is a chemistry book. The boot time is pretty fast, and henavigates through (浏览) a fewchapters before swiping into a fully rendered 3D molecule that can be spunaround to view its various building blocks. "Publishers give us all of thesource media, artwork, videos," he says, "We help them think throughhow to actually build something for this platform." Next he pulls up a music composition textbook, complete with playabledemos. It's a learning experience that attacks you from multiple sensorydirections. It's clear why this would be something a music major would love. But the most exciting part about Inkling, to me, is its notation (批注) system. Here's how it works! When you purchase a used print book, it comes with its previous owner'shighlights and notes in the margins. It uses the experience of someone whoalready went through the class to help improve your reading (how much you trusteach notation is obviously up to you). But with lnkling, you can highlight a piece of content and make notes.Here's where things get interesting, though: If a particularly importantpassage is highlighted by multiple lnkling users, that infbrmation is stored onthe cloud and is available for anyone reading the same textbook to come across.Thai means users have access to notes from not only their classmates andFacebook friends, but anyone who purchased the book across the country. Thebest comments are then sorted democratically by a voting system, meaning thatyour social learning experience is shared with the best and brightest thinkers. As a bonus, professors can even chime in (插话) on discussions. They'll be able to answer the questions ofstudents who are in their class directly via the interactive book. Of course, Inkling addresses several of the other shortcomings intraditional print as well. Textbook versions are constanly updated, motivatingpublishers by minimizing production costs (the big ones like McGraw-Hill arealready onboard). Furthermore, students will be able to purchase sections ofthe text instead of buying the whole thing, with individual chapters costing aslittle as $2.99, There are, however, challenges. "It takes efforts to build each book," Maclnnis tells me. Andit's clear why, Each interactive textbook is a media-heavy experience built from theground up, and you can tell that it takes a respectable amount of manpower toput together each one. For now the app is also iPad-exclusive, and though a few of theseeducational institutions are giving the hardware away for free, for otherstudents who don't have such a luxury it's an added layer of cost ---and anexpensive one at that. But this much is clear. The traditional textbook model is and has beenbroken for quite some time. Whether digitally interactive ones like Inklingactually take off or not remains to be seen, and we probably won't have adefinite answer for the next few years. However the solution to any problem begins with a step in a direction.And at least for now, that hazy mirage in the distance? A little more tangible(可触摸的), a little less of a dream.The biggest problem with traditional print textbooks is that A.they are not reused once a new edition comes out B.they cost hundreds of dollars every semester C.they are too heavy to carry around D.they take a longer time to revise Part I Writing(30 minutes) 1、Directions:For this part, you are allowed 30 minutes to write a short essay. You should start your essay with a brief description of the picture and then express your views on the importance of doing small things before undertaking something big. You should write at least 120 words but no more than 180 words.Part II (15 minutes) 2、What does the author say about digital textbooks? A.It's not likely they will replace traditional textbooks. B.They haven't fixed all the shortcomings of print books. C.Very few of them are available in the market. D.Many people still have difficulty using them.

统编版四年级上册读书吧必读书《山海经》真题与自测卷首语2019年秋学期开始,教育部统编教材正式走进义务教育阶段所有年级课堂。
“语文高考最后要实现让15%的人做不完!”“部编本”语文教材总主编温儒敏教授曾甩下这么一句话。
名著阅读已经是必考内容,并有指定书目,小学新教材里也增加大量课外阅读要求。
新教材从一到六年级语文教材,增加了《快乐读书吧》必读必考内容,很多小学读过的必读书内容,全国中考、高考这几年都有涉及。
教育部最新发文规定:中考、高考将适当涉及小学内容。
不知各位有没有关注最近几年全国各地的中高考试卷,很多名著都是我们小学的必读书目!下面以四、五、六年级必读书相关中考真题为例:看到没?《三国演义》《水浒传》《西游记》《老人与海》《海底两万里》《草房子》是我们四、五、六年级的必读书目!事实证明,孩子进入小学中、高年级以后,阅读和不阅读对成绩的影响开始逐渐显现了。
现在的孩子几乎都在外面上数学培训班,很多成绩较好的孩子,校内数学考试根本不相上下。
反而是语文,从低年级甚至幼儿园就能坚持有效阅读的孩子并不多。
得语文者得高考,得阅读者得语文。
对于阅读少、不读书、语言基本功不扎实的孩子而言,此次教改已经不是噩梦而是审判。
教改后考察大量语文的超纲内容、考察全科素质成为标配,不能寄希望于临时抱佛脚。

Choose the one that you think is the best answer.Mark your answers on Answer Sheet Two.TEXT AThe art of public speaking began in ancient Greece over 2,000 years ago. Now, twitter, instant messaging, e-mail, blogs and chat forums offer rival approaches to communication—but none can replace the role of a great speech.The spoken word can handle various vital functions: persuading or inspiring, informing, paying tribute, entertaining, or simply introducing someone or something or accepting something.Over the past year, the human voice has helped guide us over the ups and downs of what was certainly a stormy time.Persuasion is used in dealing with or reconciling different points of view. When the leaders met in Copenhagen in December 2009, persuasive words from activists encouraged them to commit themselves to firmer action.Inspirational speeches confront the emotions. They focus on topics and matters that are close to people's hearts. During wars, generals used inspiring speeches to prepare the troops for battle.A speech that conveys knowledge and enhances understanding can inform us. The information must be clear, accurate, and expressed in a meaningful and interesting way. When the H1N1 pandemic(流行病)was announced, the idea of “swine flu”(猪流感)scared many people. Informative speeches from World Health Organization officials helped people to keep their panic under control so they could take sensible precautions.Sad events are never easy to deal with but a speech that pays tribute to the loss of a loved one and gives praise for their contribution can be comforting. Madonna's speech about Michael Jackson, after his death, highlighted the fact that he will continue to live on through his music.It's not only in world forums where public speaking plays an important role. It can also be surprisingly helpful in the course of our own lives.If you‟re taking part in a debate you need to persuade the listeners of the soundness of your argument. In sports, athletes know the importance of a pep talk(鼓舞士气的讲话)before a match to inspire teammates. You yourself may be asked to do a presentation at college or work to inform the others about an area of vital importance.On a more personal level, a friend may be upset and need comforting. Or you might be asked to introduce a speaker at a family event or to speak at a wedding, where your language will be needed to move people or make them laugh.Great speaking ability is not something we're born with. Even Barack Obama works hard to perfect every speech. For a brilliant speech, there are rules that you can put to good use. To learn those rules you have to practice and learn from some outstanding speeches in the past.81. The author thinks the spoken word is still irreplaceable becauseA. it has always been used to inspire or persuade people.B. it has a big role to play in the entertainment business.C. it plays important roles in human communication.D. it is of great use in everyday-life context.82. Which of the following statements is INCORRECT about the role of public speaking?A. Speeches at world forums can lead to effective solutions to world problems.B. Speeches from medical authorities can calm people down in times of pandemics.C. The morale of soldiers before a battle can be boosted by senior officers' speeches.D. Speeches paying tribute to the dead can comfort the mourners.83. Public speaking can play all the following roles EXCEPTA. to convince people in a debate.B. to inform people at a presentation.C. to advise people at work.D. to entertain people at a wedding.84. According to the passage, which of the following best explains the author's view on“great speaking ability”?A. It comes from observing rules.B. It can be perfected with easy effort.C. It can be acquired from birth.D. It comes from learning and practice.85. What is the main idea of the passage?A. Public speaking in international forums.B. The many uses of public speaking.C. Public speaking in daily life context.D. The rules of public speaking.TEXT BEvery business needs two things, says Skullcandy CEO Rick Alden: inspiration and desperation. In 2001, Alden had both. He'd sold two snowboarding businesses, and he was desperately bored. But he had an idea: He wanted to make a new kind of headphone.“I kept seeing people missing their cell phone calls because they were listening to music,” he explains. Then I'm in a chairlift(索道), I've got my headphones on, and I realize my phone is ringing. As 1 take my gloves off and reach for my phone, I think, “It can't be that tough to make headphones with two plugs, one for music and one for your cell phone.” Alden described what he wanted to a designer, perfected a prototype, and outsourced(外包)manufacturing overseas.Alden then started designing headphones into helmets, backpacks - anywhere that would make it easy to listen to music while snowboarding. “Selling into board and skate shops wasn't a big research effort,” he explains. “Those were the only guys I knew!”Alden didn‟t want to be a manufacturer. And by outsourcing, he'd hoped he could get the business off the ground without debt. But he was wrong. So he asked his wife, “Can I put a mortgage(抵押贷款)on the house? She said, …What is the worst thing that can happen? We lose the house, we sell our cars, and we start all over again.‟ I definitely married the right woman!”For the next two years, Alden juggled mortgage payments and payments to his manufacturers. “Factories won't ship your product till they get paid,” he says. “But it takes four or five months to get a mortgage company so upset that they knock on your door. So we paid the factory first.”Gradually, non-snowboarders began to notice the colorful headphones. In 2006, the company started selling them in 1,400 FYE (For Your Entertainment) stores. “We knew that nine out often people walking into that store would be learning about Skullcandy for the first time. Why would they look at brands they knew and take home a new brand instead? We had agreed to buy back anything we didn‟t sell, but we were dealing with huge numbers. I t‟d killus to take back all the products.”Alden‟s fears faded as Skullcandy became the No. 1 headphone selle r in those stores and tripled its revenue to $120 million in one year. His key insight was that headphones weren‟t gadgets; they were a fashion accessory. “In the beginning,” he says, “that little white wire that said you had an iPod—that was cool. But now wearing the white bud means you‟re just like everyone else. Headphones occupy this critical piece of cranial real estate and are highly visible.”Today, Skullcandy is America's second-largest headphone supplier, after Sony. With 79 employees, the company is bigger than Alden ever imagined.86. Alden came up with the idea of a new kind of headphone because heA. was no longer in snowboarding business.B. had no other business opportunities.C. was very fond of modern music.D. saw an inconvenience among mobile users.87. The new headphone was originally designed forA. snowboarders.B. motorcyclists.C. mountain hikers.D. marathon runners.88. Did Alden solve the money problem?A. He sold his house and his cars.B. Factories could ship products before being paid.C. He borrowed money from a mortgage company.D. He borrowed money from his wife's family.89. What did Alden do to promote sales in FYE stores?A. He spent more money on product advertising.B. He promised to buy back products not sold.C. He agreed to sell products at a discount.D. He improved the colour design of the product.90. Alden sees headphones asA. a sign of self-confidence.B. a symbol of status.C. part of fashion.D. a kind of device.TEXT CI was standing in my kitchen wondering what to have for lunch when my friend Taj called.“Sit down,” she said.I thought she was going to tell me she had just gotten the haircut from hell. I laughed and said, “It can't be that bad.”But it was. Before the phone call, I had 30 years of re tirement saving in a “safe” fund with a brilliant financial guru(金融大亨).When I put down the phone, my savings were gone. I felt as if I had died and, for some unknown reason, was still breathing.Since Bernie Madoff‟s arrest on charges of running a $65 million Ponzi scheme, I‟ve read many articles about how we investors should have known what was going on. I wish I could say I had reservations about Madoff before “the Call”, but I did not.On New Year‟s Eve, three weeks after we lost our savings, six of us M adoff people gathered at Taj's house for dinner. As we were sitting around the table, someone asked, “If you could have your money back right now, but it would mean giving up what you have learned by losing it, would you take the money or would you take what losing the money has given you?”My husband was still in financial shock. He said, “I just want the money back.” I wasn't certain where I stood. I knew that losing our money had cracked me wide open. I‟d been walking around like what the Buddhists call a hungry ghost: always focused on the bite that was yet to come, not the one in my mouth. No matter how much I ate or had or experienced, it didn‟t satisfy me, because I wasn‟t really taking it in, wasn't absorbing it. Now I was forced to pay attention.Still, I couldn't honestly say that if someone had offered me the money back, I would turn it down.But the other four all said that what they were seeing about themselves was incalculable, and they didn‟t think it would have become apparent without the gro und of financial stability being ripped out from underneath them.。

(共15小题,每小题2分,共30分)ALang Lang was born in Shenyang. His father Lang Guoren is also a famous musician who specializes in the erhu, a Chinese instrument. At the age of two, Lang Lang watched Tom and Jerry cartoon on television when he first heard Western classical music. According to Lang Lang, this first contact with Western music is what motivated him to learn piano. He began lessons with Professor Zhu Yafen at three. At the age of five, he won first place at the Shenyang Piano Competition.When he was nine years old, Lang Lang attended his audition (试音) for Beijing’s Central Conservatory of Music, and, having difficulties with his lessons, he was forced to leave his piano tutor’s studio for lack of talent. His music teacher at his state school noticed Lang Lang’s sadness, and decided to comfort him by playing a record of Mozart’s Piano sonata (奏鸣曲); she asked him to play along with the second movement (乐章). This reminded Lang Lang of his love of the instrument. “Playing the sonata brought me hope again,” said Lang Lang.Lang Lang was later admitted into the conservatory under the study of Professor Zhao Pingguo. In 1993, Lang Lang won the Xinghai Cup Piano Competition in Beijing and was awarded first prize for outstanding artistic performance at the fourth International Competition for Young Pianists in Ettlingen, Germany, the next year. In 1995, at thirteen, he played the Op. 10 and Op. 25 études (练习曲) by Chopin at the Beijing Concert Hall and, in the same year, won first place at the International Tchaikovsky Competition for Young Musicians in Japan. At thirteen he was a featured soloist at the China National Symphony’s inaugural (开幕的) concert, which was broadcast by China Central Television and attended by President Jiang Zemin.21. What can we infer from the first paragraph?A. Lang Lang’s father played the erhu well.B. Lang Lang didn’t like cartoons when young.C. Lang Lang’s family forced him to learn piano.D. Lang Lang began his piano lessons at five.22. Which of the following orders can correctly describe Lang Lang’s process of growth?①Lang Lang began his piano lessons with Professor Zhu Yafen.②Lang Lang won first place at the International Tchaikovsky Competition for Young Musicians.③Lang Lang was later admitted into the Central Conservatory of Music.④Lang Lang was awarded first prize at the fourth International Competition for Young Pianists.⑤Playing Mozart’s Piano sonata brought Lang Lang hope again.A. ①③④②⑤B. ①⑤②③④C. ①⑤③②④D. ①⑤③④②23. When was Lang Lang born according to the text?A. In 1982.B. In 1985.C. In 1993.D. In 1995.BHalf the world’s population could face a shortage of food by 2100 due to climate change, a new report by US scientists warns. Rapid global warming is likely to reduce crop production in the tropics and subtropics (热带和亚热带地区), according to Professor David Battisti of the University of Washington.The most extreme summers of the last century will become common, he says. We must immediately create crops that can bear heat and drought if we are to adapt in time, he writes in Science journal.“The stresses on global food production from temperature alone are going to be huge,” said Mr. Battisti. “And that doesn’t take into account water supplies stressed by the higher temperatures.”He worked with Professor Rosamond Naylor on Food Security and the Environment, to examine the influence of climate change on the world’s food supplies. They predict there is a greater than 90% probability that by 2100, the average growing season temperatures in the tropics and subtropics will be higher than any temperatures recorded there to date.“We are taking the worst of what we’ve seen historically and saying that in the future it is going to be a lot worse unless there is some kind of adaptation,” said Professor Naylor. “This is a powerful reason for us to invest (投资) in adaptation, because it is clear that this is the direction we are going in terms of temperature and it will take decades to develop new food crop varieties that can better bear a warmer climate.”In the tropics, the higher temperatures could be expected to cut production of the primary food crops by 20-40%, the researchers said. Rising temperatures are also likely to reduce soil moisture (湿度), cutting production even further.Three billion people live in the tropics and subtropics now, and their number is expected nearly to double by the end of the century.“You are talking about hundreds of millions of additional people looking for food because they won’t be able to find it where they find it now,” said Professor Battisti.Crop failures would not be limited to the tropics, the scientists concluded.24. According to Professor David Battisti, what should be done to deal with crops reduction caused byglobal warming?A. To plant more crops.B. To develop new crops.C. To control population growth.D. To improve farming technology.25. What does the underlined word “this” in Paragraph 5 refer to?A. To reduce the temperature.B. New food crop variety.C. To invest in adaptation.D. Some kind of adaptation.26. We can know from the text that _____.A. the number of people living in the tropics is reducingB. temperatures will rise most in the tropicsC. crop failures will be a global problemD. new food crop varieties will be developed soon27. The text intends to tell us that _____.A. our world is becoming warmer and warmerB. high temperatures may cause food shortagesC. the consequences of global warmingD. the ways to adapt to high temperaturesCMost people consider skydiving (高空跳伞) a product of the 20th century, but its history actually goes further back than that. The Chinese attempted to parachute (跳伞) in the 10th century, a thousand years before we did. The Chinese did what we would today call base diving; that is, they jumped off a place that would allow them to float from a height to the ground.The first person to attempt to parachute was a Frenchman named Jacques Garnerin. He jumped from his hot-air balloon at the end of the 18th century and did tricks on the way down and stupefied the crowds by landing safely on the ground. At the end of the 19th century, Kathie Paulus, a brave German woman, became famous for her skydiving skills.Once the airplane was invented, skydiving took on a whole new form. The airplane made it possible to dive from greater heights at greater speeds, allowing for more range in the movements in the air. A woman named Tiny Broadwick became the first woman to jump from a plane in 1913 and dive free fall in 1914.Skydiving was not called skydiving until the middle of the 1950s, when Ronald Young invented the word. It had been called parachuting before this and was mainly used by the military to land troops in inland locations, or for pilots to jump out of their planes when necessary. Once World War Iwas over, parachuting became a sport, which we now call skydiving.After World War II, this activity became more a hobby than a military action. Soldiers were trained in parachuting and enjoyed the thrill so much that they continued on for fun. From this, teams and competitions were formed. Skydiving schools appeared in the late 1950s and now it is a recognized extreme sport enjoyed by many.28. The underlined word “stupefied” in Paragraph 2 probably means “______”.A. disappointedB. encouragedC. surprisedD. attacked29. Who was the first woman to jump from a plane?A. Jacques Garnerin.B. Kathie Paulus.C. Tiny Broadwick.D. Ronald Young.30. Which of the following is TRUE?A. The Chinese attempted different skydiving skills in the 10th century.B. Skydiving became popular after the airplane was invented.C. The word skydiving was first used in a military action.D. There were no skydiving schools until the late 1950s.31. What would be the best title for this text?A. The history of skydivingB. The popularity of skydivingC. What is skydiving?D. Why is skydiving an extreme sport?DIn this article you will discover several techniques you can use to improve your interpersonal relations with friends, family, coworkers, and employees. In fact, you can use these techniques to influence others to have a positive attitude toward you in just about any type of relationship.1. Don’t crit icize or complain about people.There’s no faster way to create resentment (忿恨) toward you than to criticize or complain about a person. Instead of telling people they’re doing something wrong, consider asking them questions to try to find out why they do what they do. Offer them an alternative in a way that comes across as (给人以……的印象) trying to help. Show them how doing things the way you would like them done can benefit them or lead to reward.2. Appreciate people.I’ll let you know a secret that can vastly improve your interpersonal relations very quickly: whenever you see someone, imagine them wearing a flashing sign on their chest that says APPRECIATE ME, PLEASE! Then, give them what they want.3. Be genuinely interested in others.You’ll make a lot of friends by being interested in others. Not everyone will admit it, but t hetruth is, most people’s favorite subject is themselves. Use this to your advantage. Become genuinely interested in other people. Ask them questions. Talk to them about things they’re interested in. Put the focus on them. You’ll quickly gain their friend ship.4. Be a good listener.This goes back to the principle of focusing on the other person. Listen more than you speak and encourage others to talk about themselves and you’ll quickly develop good interpersonal relations with them.5. Make others feel important.If someone is important to you in any way, tell them so! This goes for any type of interpersonal relationship! People like to feel important. Give them what they want and they will love you for it.32. When your friends do something wrong, you are advised to ______.A. point out their mistakesB. correct their mistakesC. put forward a new planD. solve the problem for them33. What’s the purpose of an imagined flashing sign on people’s chest?A. To attract others’ attenti on.B. To remind people to talk to them.C. To remind people to praise them.D. To help people to remember them.34. What should we do if we want to improve interpersonal relations according to the text?A. Listen more than we speak.B. Try to argue when we are right.C. Get people to be interested in us.D. Talk more about things we’re interested in.35. Which of the following is true?A. You can tell people directly when they are doing something wrong.B. You’ll make a lot of friends only by being interested in others.C. The fastest way to create resentment towards you is to criticize or complain about a person.D.
