Texas Tech University is even offering a class called Improving Your Sleep Habits. People suffering from sleep loss are at an increased risk from obesity, psychological problems and car crashes. Students who don't get enough sleep have poor attendance and lower grades. On top of all that, (2)a new study published in the journal Learning and Memory finds you are probably better off sleeping than making last-minute preparations for a test. Two hundred college kids were taught to play some unfamiliar video games. Subjects who learned the games in the morning lost some skills when they played again 12 hours later, (1)but they did much better after getting a good night's sleep. So if you really want to do your job well, don't forget to get some sleep.Questions 1 and 2 are based on the news report you have just heard.What is the news report mainly about?解析：主旨大意题。
2017年12月大学英语四级参考答案及听力原文
2017年12月丨四级听力*注：2017年12月全国大学英语四级考试共有两套听力。
听力第一套听力原文：A 9-year-old girl in New Mexico has raised more than $500 for her little brother who needs heart surgery in Houston, Texas this July. Addison Witulski's grandmother Kim Allred, said Addison probably overheard a conversation between family members talking about the funds needed to get her little brother to treatment. "I guess she overheard her grandfather and me talking about how we're worried about how we're going to get to Houston, for my grandson's heart surgery," said Allred. She decided to go outside and have a lemonade stand and make some drawings and pictures and sell them.” That's when Addison and her friends Erika and Emily Borden decided to sell lemonade for 50 cents a cup and sell pictures for 25 cents each.Before Allred knew it, New Mexico State Police Officers were among the many stopping by helping them reach a total of$568. The family turned to social media expressing their gratitude saying, "From the bottom of our hearts, we would like to deeply thank each and every person that stopped by!"1: Who did Addison raise the money for?2: How did Addison raise the money?News Report 2:Last week, France announced that the country will pave 621 miles of road with solar panels over the next five years with the goal of providing cheap, renewable energy to five million people. Called the Ward Way, the roads will be built through joint efforts with the French road building company Colas and the National Institute of Solar Energy. The company spent the last five years developing solar panels that are only about a quarter of inch thick and are strong enough to stand up to heavy highway traffic without breaking or making the roads more slippery. The panels are also designed so that they canbe installed directly on top of the existing roadways, making them relatively cheap and easy to install. France is the first country to kick around the idea of paving its roads with solar panels. In November 2015, the Netherlands completed a229-foot long bike path paved with solar panels as a test for future projects. However, this is the first time a panel has been designed to be laid directly on top existing roads and the first project to install the panels on public highways.3: What was France’s purpose o f constructing theWard Way?4: What is special about the solar panels used in the Ward Way?News Report 3Lions have disappeared from much of Africa, but for the past few years scientists have wondered if the big cats were hanging on in remote parts of Sudan and Ethiopia. Continuousfighting in the region has made surveys difficult. But scientists released a report Monday documenting with hard evidence the discovery of "lost lions." A team with Oxford University’s Wildlife Conservation Research Unit, supported by a charity organization, spent two nights in November camping in a national park in northwest Ethiopia on the Ethiopia-Sudan border. The researchers set out six camera traps, capturing images of lions, and the identified lion tracks. The scientists concluded that lions are also likely to live in a neighboring national park across the border in Sudan. The International Union for Conservation of Nature had previously considered the area a "possible range" for the species, and local people had reported seeing lions in the area, but no one presented convincing evidence.5: What has made it difficult to survey lions in remote parts of Sudan and Ethiopia?6: What was the main purpose of the research?7: What did the researchers find in the national park?Conversation OneM: I beg you’re looking forward to the end of this month. Aren’t you?W: Yes, I am. How did you know?M: David told me you had a special birthday coming up. W: Oh, yes. That’s right. This year would be my golden birthday.M: What does t hat mean? I’ve never heard of a golden birthday.W: I’ve actually just learned of this concept myself. Fortunately, just in time to celebrate. A golden or lucky birthday is when one turns the age of their birth date. So, for example, my sister’s birthday i s December 9th and her golden birthday would have been the year she turns 9 years old. Come to think of it , my parents did throw her a surprise party that year.M: Interesting. Too bad I missed mine. My golden birthday would’ve been four years ago. I assu medly got a big plan then.W: Actually yes. My husband is planning a surprise holiday for the two of us next week. I have no idea what he’s gotten in mind, but I’m excited to find out. Has he mentioned anything to you?M: He might have.W: Anything you’d like to share? I’m dying to know what kind of trip he has planned where we’re going.M: Yeah, nothing at all.W: Not a clue. Hard to imagine, isn’t it! Though I must say, I think it has been even more fun keeping the secret for me the past few weeks.M: I’m sure both of you will have a fantastic time. Happy golden birthday! I can’t wait to hear all about it when you get back.8. What does the woman looking forward to?9. What did the woman’s parents do on her sister’s lucky birthday?10. What is the woman eager to find out about?11. What does the man say at the end of the conversation? Conversation TwoW: Mr. Green, What do you think makes a successful negotiator?M: Well, It does hard to define, but I think successful negotiators have several things in common. They are always polite and rational people, they are firm, but flexible. They can recognize power and know how to use it. They are sensitive to the dynamics in the negotiation, the way it raises and falls, and how may change the direction. They project the image of confidence, and perhaps most importantly, they know when to stop.W: And what about an unsuccessful negotiator?M: Well, this probably all of us when we start out. We are probably immature and over-trusting, too emotional or aggressive. We are unsure of ourselves and want to be liked by everyone. Good negotiators learn fast, pool negotiators remain like that and go on losing negotiations,W: In your opinion, can the skills of negotiation be taught? M: Well, you can teach someone how to prepare for negotiation. There perhaps six stages in every negotiation, get to know the other side, stay your goals, start the process, clarify there is a disagreement or conflict, reassess your position, making acceptable compromise, and finally reach some agreements and principals. These stages can be studied, and strategies to be used in each can be planned before-hand. But I think the really successful negotiator is probably born with the sixth sense that may respond properly to the situation at hand.W: The artistic sense you just described?M: Yes, that’s right12. What’s the man say about good negotiators?13. What does the man say, maybe the most important thing to a successful negotiator?14. How is a good negotiator different from a poor one?15. What’s the first stage of a negation according to the man?Passage OneSome people wonder why countries spend millions of dollars on space projects. They want to know how space research helps people on earth. Actually, space technology helps people on earth every day. This is called spin-off technology. Spin-off technology is space technology that is now used on earth. In early space programs, such as the Apollo missions of the 1960s and 1970s and in the space shuttle missions today, scientists developed objects for the astronauts to use on the moon and in space. We now use some of these objects every day. For example, we have quartz crystal clocks and watches accurate to within one minute a year. We purify the water we drink with the water filter designed for the astronauts to use inspace. The cordless hand held tools we use in our homes, such as vacuum cleaners, flashlights, drills came from the technology of these early space programs. On cold winter days, we can stay warm with battery-operated gloves and socks, especially made coats and jackets. All the clothes are similar to the space suits designs that kept astronauts comfortable in the temperatures of the moon, in our spin offs from space technology. These products are only a few examples of the many ways space technology helps us in our everyday lives. No one knows how new spin off technology from the international space station will help us in the future.16. What do some people want to know about space exploration?17. What did scientist do for the space shuttle missions?18. What does the speaker say about the quartz crystal clocks and watches?Passage TwoWell, if I could get back in history and live, I'd like to get back to the 18th century and perhaps in colonial America in Yankee new England where one of my ancestors lived, because it was the beginning of something. By the 18th century, there was a feeling of community that had grown. My ancestor was the preacher traveling around countryside. People lived in small communities. It was fisherman and farmers who provided fresh food that tasted and looked like food. Unlike today’s supermarkets, and there were small towns and New York wasn't that far away. I'm deeply attached to the puritan tradition not in a religious sense. But they believed in working for something, working for goals. And I like that. They worked hard at whatever they did, but they had a sense of achievement. They believed in goodness, in community, and helping one another. I love the colonial fabrics or the silver works, the furnishings, the combination of elegance simplicity. I'd love it. The printing, the books, I’m very attached to all that kind of thing. That may not all be very entertaining in the modern sense of the world, but I would have enjoyed spending my evenings in that environment, discussing newideas, building a new world, and I can see myself sitting on a small chair by the fire doing needle work.19. Why does the speaker say she would like to go back and live in the 18th century America?20. What does the speaker say about the Puritans?21. What would the speaker like doing if she could go back to the past?Passage threeIf you are lost in the woods, a little knowledge concerned with some people called a hardship into an enjoyable stay away from the troubles of modern society. When you think you're lost,sit down on the log or rock, or lean against the tree, and recite something you are memorized to bring your mind to the point where is under control. Don’t run blindly if you must move, don't follow stream unless you know it, and in that case you're not lost. Streams normally flow through wide land before theyreach a lake or river though there are more eatable plants, there may also be wild animals, poisonous snakes, and other hazards. Many experts feel it is the wisest to walk up hill. At the top of most hills and mountains are trails living back to civilizations. If there are no trails, you're much easier to be seen on top of the hill. And you may even spot the highway or railroad from this point. Nowadays, the first way some of you search for you is by air. In the wide lands or in dense grass, we're very hard to spot. Anytime you are going to the woods, somebody should know where you're going, and when you are expected to return, also when someone comes to looking, you should be able to signal to them.22. What does the speaker advise you to do first if you are lost in the woods?23. What will happen if you follow an unknown stream in the woods?24. What do many experts think is the wisest thing to do if you're lost in the woods?25. What should you do before you go into the woods?参考答案：1. D) Her little brother.2. B) By selling lemonade and pictures.3. B) Providing clean energy to five million people.4. C) They can be laid right on top of existing highways.5. C) Endless fighing in the region.6. D) To find evidence of the lions'disappearance.7. A) Lions'tracks.8. D) Her "lucky brithday".9. A) Threw her a superise party.10. C) The trip her husband has planned.11.B)He is eager to learn how the couple's holiday turns out.12.D)They are sensitive to the dynamics of a negotiation.13.A)They know when to stop.14.B)They learn quickly.15.C)Get to konw the other side.16.A)How space research benefits people on Earth17.C)They developed objects for astronauts to use in outer space.18.B)They are extremely accurate.19.C)It marked the beginning of something new.20.D)They believed in working for goals.21.B)Doing needlework by the fire.22.A)Sit down and try to calm yourself.23.C)You may expose youself to unexpected dangers.24.A)Walk uphill.25.D)Inform somebody of your plan.听力第二套参考答案：1.

英语专业四级考试答案ListeningPART I DICTATIONThink Positively and Feel PositivelyAre you confident or insecure in a difficult situation?Do you react positively or negatively?The answer may depend in part on whom you are around.A study found that negative thinking can be contagious in some cases. For example，the researchers studied 103 college roommates. They measured each roommate’s tendency towards negative thinking. It was found that thinking patterns can be contagious. Students with a negative thinking roommate became more depressed themselves and students with more positive thinking roommates were more likely to become more positive as well.PART II LISTENING COMPREHENSIONSECTION A TALK1. success2. challenging settings3.

Parents claim that by doing so，they can save a lot of money born of busy school holidays. Educational officials strongly oppose this tendency on the ground that it encourages truancy，which in turn damages a child’s education. From my perspective，the merits of banning term-time holidays outweigh its demerits.To begin with，taking tough measures on this kind of truancy is conducive to the normal teaching process，one of the key elements to guarantee kid’s academic performance. As we know，currently，teachers have the discretion to approve a certain time of absence from school for each child，which is supposed to be for illness and is not supposed to be granted for holidays. By definitely abolishing the right of head teachers to “authorize absence” from the classroom，thoseteachers can rarely be pestered by parents who want to take children to go on a holiday just to save money，which severely disrupts teaching process. What ‘s more，without strict penalties imposed on the parents who lead to their kid’s playing truant，those parents can gradually view asking for holiday leave as a right. Once this cultural expectation is formed，the level of truancy will dramatically increase.Accordingly，the growing trend of term-time holidays should be banned with no delay. In this way，teachers can impart knowledge without disturbance and parents will be deterred from saving money at the expense of sacrificing their kid’s education.专四听力原文PART I DICTATIONThink Positively and Feel PositivelyAre you confident or insecure in a difficult situation?Do you react positively or negatively?The answer may depend in part on whom you are around.A study found that negative thinking can be contagious in some cases.

Students with a negative thinking roommate became more depressed themselves and students with more positive thinking roommates were more likely to become more positive as well.PART II LISTENING COMPREHENSIONSECTION A TALKWhat is Grit?Good morning，everyone. Today I would like to talk about my recent research project，concerning the key to success. I would like to start my topic with my own story.When I was 27 years old，I left for a demanding job - teaching seventh graders math in the New York City public schools. And like any teacher，I made quizzes and tests. I gave out homework assignments. When the work came back，I calculated grades.What struck me was that I.Q. was not the only difference between my best and my worst students. Some of my strongest performers did not have super I.Q. scores. Some of my smartest kids weren't doing so well.And I felt interested in knowing the reason why the students’ math performance is not that closely related to their IQ scores. I started studying kids and adults in all kinds of challengingsettings，and in every study my question was，who is successful here and why?My research team and I went to West Point Military Academy. We tried to predict which students would stay in military training and which would drop out. We went to the National Spelling Contest and tried to predict which children would advance furthest in competition. We worked with private companies，asking，which of these sales people is going to keep their jobs?And who's going to earn the most money?We went to many places. And finally，one characteristic emerged as a significant predictor of success. And it wasn't social intelligence. It wasn't good looks，physical health，and it wasn't I.Q. It was grit. What is grit?Well，grit is passion and perseverance for very long-term goals. Grit is sticking with your future，day in，day out，not just for the week，not just for the month，but for years，and working really hard to make future a reality. Grit is living your life like it's a marathon，not a sprint.A few years ago，I started studying grit in the Chicago public schools. I asked thousands of high school juniors to take grit questionnaires，and then waited around more than a year to see who would graduate. It turned out that grittier kids were significantly more likely to graduate，even when I matched them on every characteristic I could measure，things like family income，test scores，and so on. To me，the most shocking thing about grit is how little we know，how little science knows，about building it. Every day，parents and teachers asked me，"How do I build grit in kids?How do I keep them motivated for the long run?" Our data show very clearly that there are many talented individuals who simply do not follow through on their commitment. In fact，in our data，grit is usually unrelated to measures of talent.So far，the best idea I've heard about building grit in kids is something called "growth mindset." Growth mindset is the belief that the ability to learn is not fixed，that it can change with your effort. Kids with grit are much more likely to persevere when they fail，because they don't believe that failure is a permanent condition.So growth mindset is a great idea for building grit. But we need more. And that's where I'm going to end my talk，because that's where we are. That's the work that stands before us. We have to be willing to fail，to be wrong，to start over again with lessons learned.As a conclusion，we need to be gritty about getting our kids grittier. Next time，I would like to share with you my experience in building up students’ grit.Section BConversation OneW：Hello，this is Kate Smith. I’m calling from ABC Company.M：Oh，hello，Kate. Great to hear from you.W：You’ve already been told that you’ve been short-listed for interview.M：Oh，yes.W：W ell we’re very excited about meeting you. Ok，I just want to talk you through the procedure for the day. Someone will meet you when you arrive，and then bring you up to meet myself and Arthur Miller，the CEO.M：Ok sounds good. So will you be the only members of the interview panel there then?W：Yes，it’ll be just me and Arthur who will talk to you. The interview will be in three parts – first of all we’ll ask you some general questions about yourself and your educational andprofessional background，and then we’ll move on to specifics.M：Oh，er，Specifics?Well er，what kind of questions will you be asking?W：Well，it’ll be very similar to the personal statement you submitted with your CV - we’ll be expecting you to to give actual examples of problems you’ve faced and solved，and of what you feel are the major successes in your career so far.M：Ok well yeah，that sounds great –can’t wait！W：Then there’ll be a chance for you to ask us any questions - about the job itself，or ABC Company in general...M：Oh，erm，ok...I’ll think of something!W：After that，we’d like you to give a short presentation on how you see ABC as a company progressing，and how you see yourself taking us there.M：Ok so will I be expected to give like a formal style presentation?W：It can be as formal or informal as you like. There’ll be a computer and a data projector there available. If you need anything else，just let us know.M：Oh，erm ok，a presentation！I’ll think of something. I haven’t done one of those in a while... W：Is that all clear?M：Yes.W：Great，so，Daniel，I’ll see you at 11am，Thursday，next week.M：Ok，great. I look forward to meeting you！Thanks，bye.W：Bye.Questions 1 to 5 are based on Conversation One.Question 1：Why does the woman call the man?Question 2：What kind of questions can the man ask in an interview?Question 3：Which is the last part of the interview?Question 4：What might b e expected from the man’s presentation?Question 5：When is the interview scheduled?Conversation TwoW：It says a growing number of students are making a major hole from the minute they enter the real world，because they are already some of them，more than 100,000 dollars in debt. With usnow is Mark Spencer. He is the senior financial analyst from SBC Bank. Welcome to you.M：Thank you，nice to be with you.W：Now，I guess there are two kinds of debts，good debt and bad debt. Where does this go? M：Well，student loan debt is traditionally considered good debt，but the problem for many students and their families is that the cost of colleges has been going up at 6-8% a year，far faster than the income，far faster than the standard of living. That means debt’s taking on a bigger and bigger role in financing education.W：How much debt is too much debt for-for one student?M：Well，one guideline is that you look at the first-year salary in your field after graduation，and use that as a barometer，but even then…W：Is that right?M：Well，you are talking big payments even in that instance. For example，30,000 dollars’ worth of debt，if you are gonna repay that over 10 years，you are talking more than 300 dollars a month’s debt in payments every month for 10 years.W：But there are surely more than one way to get a loan for college. There are government programs，there are so many kinds of grants. What’s-what’s the best advice for people who are looking for these loans to try to keep themselves from going under?M：I understand that loans are just one way of college finance. Take advantage of the other opportunities，things like a college savings’ plan. Let-let you save on a tax advantage basis，so you can put money away in these accounts and withdraw tax-free to pay for that education. W：So it’s important to start early and that really reduces their reliance on debt later.M：Another thing. Leave no stone unturned，looking at grants，scholarships，even on campus jobs.I mean every dollar you get that way is seen as another dollar you don’t have to borrow later. W：The kinds of jobs that so many students，fresh off students，like to go into，eh——charitystuff，volunteer work. This debt is eliminating a lot of that，isn’t it?M：I think that’s the social cost，really，I mean，you know，when you consider that，you know，people may pass up a rewarding career and charitable work or a non-profit organization，because they have to get a higher salary some places else to pay off that debt.W：Yeah，that’s for sure. Mark Spencer，senior financial analyst from SBC Bank，Mark，good you could be here.M：Thank you.Questions 6 to 10 are based on Conversation TwoQuestion 6：What is the interview mainly about?Question 7：How does the cost of education change every year?Question 8：What is used to measure student loan debt as a guideline?Question 9：What is the advantage of joining a college savings’ plan?Question 10：What is the possible social cost of college loan?。

W: I bet they were frozen. M: What? W: The fish sticks. M: Of course they were frozen. We are hundreds of miles from the Ocean. The cafeteria can't afford to fly in fresh fish. W: I just mentioned it because an anecdote Professor Chambers told me in my American social history class this morning. M: He talked about fish sticks? W: Not exactly. But he did talk about frozen fish. OK, this is back in 1912, right? It's 20 degrees below zero. And this guy Clarence Birdseye's out ice-fishing. M: Where is this, Antarctica? W: No. Massachusetts I think. Anyway he catches a fish and drops it beside him on the ice and it freezes solid. M: So? W: So, {{U}}later at home he thaws out the fish in a bucket of water and it's alive. Of course Birdseye is amazed.{{/U}} But he eventually figures out that the fish froze so fast that no large ice crystals formed. M: What do you mean? W: {{U}}Look, usually when a plant or animal cell freezes, large ice crystals form inside and eventually tear the cell wails. That's what kills the frozen plant or animal. And also what changes the taste of something that's been frozen. But if you freeze something quickly, only very small ice crystals form.{{/U}} So Birdseye invented the process of quick freezing food. M: And that was the beginning of frozen foods? W: Right. [解析] 本题考查原因。
