There were no injuries. It is not the first time one of Google's famed self-driving cars has been involved in a crash, but it may be the first time it has caused one.On February 14th, the self-driving car, travelling at two miles per hour, pulled out in front of a public bus going fifteen miles per hour.The man in the Google vehicle reported that he assumed the bus would slow down to let the car out, and so he did not switch to the manual mode.In a statement, Google said: "We clearly bear some responsibility, because if our car hadn't moved, there wouldn't have been a crash."“That said, our test driver believed the bus was going to slow or stop to allow us to merge into the traffic, and that there would be sufficient space to do that.”The company's self-driving cars have done well over a million miles across various states in the US, and until now have only reported minor accidents.1. According to Google, what was the cause of the accident?2. How have Google’s self-driving cars performed so far?Questions 3 and 4 are based on the news report you have just heard.Thousands of bees left a town after landing on the back of a car when their queen got stuck in its boot. Tom Moses, who works at a nearby national park, noticed a “brown patch” on the back of the car after the owner parked it to do some shopping. When he looked closer he realized it was a huge group of bees.Moses said: “I have never seen that many bees in one spot. It was very unusual. They were very close together and there was a lot of noise and movement. “It was interesting to see such a strange sight, but there were a lot of people around and I was a bit worried of the bees and the people stopping to look. I thought that someone might do something stupid.”Moses called two local bees specialists who helped remove the bees by attracting them into a box. Moses spent three hours looking after the bees -- and was stung five times.He said: “My stings are a bit painful, but I am pleased that all worked out and I could help. People need to realize that bees are valuable and they should be looked after.3. What do we learn about Tom Moses?4. What do we know about the bees on the back of the car?Questions 5 to 7 are based on the news report you have just heard.A new species of snake has been discovered on a remote island in the Bahamas.Scientists identified 20 of the one meter-long snakes during two trips to the Caribbean islands. The second trip was made in October last year.One of the creatures made a dramatic appearance by moving on to the head of the team leader as he slept.The snake has been named silver boa because it is metallic colored and the first specimen found was climbing a silver palm tree.The team was led by Dr. Graham Reynolds, from Harvard University. The scientist confirmed the snake was a previously unknown species after conducting a genetic analysis of tissue samples.Commenting on the find, snake expert Robert Henderson from the Milwaukee Museum of Natural History, said: “Worldwide new species of frogs are being discovered and described quite regularity. New species of snakes, however, are much rarer.”5. What is the news report mainly about?6. What do we learn about the scientific team leader?7. How did the newly discovered creature get its name?Section BQuestions 8 to 11 are based on the conversation you have just heard.W: Did you enjoy your stay with us, Mr. Brown?M: Yes, very much. I had a wonderful time here. Now I'm going to the airport. My flight leaves in less than two hours, so could you tell me what is the quickest way to get there?W: Well, we can call a taxi for you. We also have a free airport shuttle service.M: That sounds great, but will the shuttle get me to the airport in time?W: Yes, it should. The next shuttle leaves in 15 minutes. And it takes some 25 minutes to get to the airport.M: Fantastic! I'll just wait in the lobby. Will you please let me know when it's leaving?W: Of course, sir.M: Now, I would like to settle my mini-bar bill. How much is that?W: Let's see. It comes to 37 dollars and 50 cents. How would you like to pay for it?M: I'll pay with my credit card. Thanks. But I'll need a receipt, so I can charge it to my company. W: Absolutely! Here you are, sir. If you like, I can leave your bags with the porter. And he can load them onto the shuttle for you when it arrives.M: That would be great. Thank you.W: Would you like to leave a comment on our webpage when you have time?M: Sure.

The other day, he came home from school almost in tears. His teacher said if he went on like that, his face would get stuck when the winds changed.W: And he believed her?M: Yeah, he’s only a little boy. Don’t you remember all those things we used to believe when we were little? I remember my aunt Mary used to say if you swallow a cherry stone, a tree would grow out of your mouth. And I’m still terrified today, sort of subconsciously. You know, if I swallow one by mistake…W: Yeah, I suppose you're right. The one that used to get me was that swans could break your leg when they blow of the wing.M: They can, can’t they? I always thought they could.W: No, they are not that strong. But there’s another one even more terrifying. That is, if you put a post stamp on upside down, you will go to prison.M: No, never heard of that. But my grandmother was a terror for that kind of thing. For example, she would say, you will get a spot on your tongue if you tell a lie. If you eat stale bread, your hair will curl. And here is one more. We went on a campaign trip once in Italy, and my wife spent the whole time worrying about bats getting into her hair. She said her grandmother reckoned you had to shave your head to get it out. My wife was really terrified.W: Silly, isn’t it? But that’s how some parents try to keep their kids from doing the wrong thing or getting into trouble.12. What does the man say about Ben?13. What did aunt Marry used to do when the man was a child?14. What does the woman believe swans could do?15. What did the grandmother of the man’s wife say?Section CQuestions 16 to 18 are based on the passage you have just heard.If I could go back in history and live when I liked, I wouldn't go back very far. In fact, I'd like to relive a period I've already lived -- the 1960s.I was in my twenties, and everything was being renewed. People would come in out of a formal and almost Victorian attitude, and you really felt anything was possible. Meeting people was the thing, and you went to coffee bars where you met friends and spent the evening. The cinema, the theater, all that was every exciting with new things coming out. In fact, we seemed to be out all the time! I don't really remember working --of course, I was a student --or sitting around at home very much. That just wasn't where the scene was, even eating! It was the first time ordinary people started going out to eat. We were beginning to be adventurous about food, but we were more interested in meeting people than in eating or drinking. And dress, yes, that was the revolution. I mean, girls went around in really short skirts, and wore flowers in their hair. And men were in jeans, and could wear their hair long too. It was a wonderful period. It was like living in an age you could never have imagined, and that never has come back. We didn't have much money, but it didn't matter. And there was plenty of opportunity to do whatever you felt like doing.16. Why does the speaker say he would like to relive the 1960s?17. What does the speaker say was the most popular thing to do at that time?18. What do we learn about the speaker?Questions 19 to 21 are based on the passage you have just heard.Dogs, man's best friends, have a clear strategy for dealing with angry owners—they look away. New research shows that dogs limit their eye contact with angry humans. The scientists suggest this may be an attempt to calm humans down. This behavior may have evolved as dogs gradually learn they could benefit from avoiding conflicts with humans.To conduct the tests, the University of Helsinki researchers trained 31 dogs to rest in front of a video screen. Facial photos of dogs and humans were displayed on the screen for 1.5 seconds. They showed threatening, pleasant and neutral expressions. Nearby cameras tracked the dogs' eye movements.Dogs in the study looked most at the eyes of humans and other dogs to sense their emotions. When dogs looked at expressions of angry dogs, their eyes rested more on the mouth, perhaps to interpret the threatening expressions. And when looking at angry humans, they tended to turn away their gaze.Dogs may have learned to detect threat signs from humans and respond by trying to make peace. According to researcher Sanni Somppi, avoiding conflicts may have helped dogs develop better bonds with humans.The researchers also note that dogs scan faces as a whole to sense how people are feeling, instead of focusing on a given feature. They suggest this indicates that dogs aren't sensing emotions from a single feature, but piecing together information from all facial features just as humans do.19. What do dogs do when they are faced with angry humans?20. What does a dog do when it sees the expressions of angry dogs?21. How does a dog sense people's feelings?Questions 22 to 25 are based on the passage you have just heard.Winter in many places is very cold. There is lots of snow around, and the ground freezes, which can make life difficult for animals. People in cold places live in warm houses and have learned to adapt. What do animals do? There are three main ways that animals survive the cold in winter -- sleep, adapt or migrate.Some animals, such as bears, frogs and snakes, sleep all winter. They sleep very deeply and need little or no food. While sleeping, their body temperature drops, and their heartbeat slows down. To prepare for this before winter, these animals eat extra food to become fat, which gives them the energy they need while they sleep.Other animals adapt, for example, by staying active in winter. It is often hard for them to find food. So some animals, such as mice, collect extra food before winter, and hide it. When winter comes, they return to their hiding places to eat the food. Some animals grow thicker fur, or live in tree holes or underground to stay warm.Some birds migrate by flying to a warmer place for the winter, where they can find more food. Some fly very long distances, including one kind of bird that flies from the remote north of the world all the way to the distant south. Some birds fly in groups for safety, while others fly alone.22. What does the speaker say about animals in winter?23. What do we learn about animals that sleep through winter?24. How do animals like mice adapt to the severe winter?25. Why do some birds fly in groups when migrating according to the speaker?2017年6月大学英语四级考试真题听力原文及参考答案（第２套）Part I WritingSelling Second-hand Course BooksSecond-hand course books are being sold now.

Still, 60% drivers would like to get some kind of self-driving feature, such as automatic braking or self-parking the next time they buy a new car. The attitudes are published in a new AAA survey of 1,800 drivers. Advocates of self-driving cars argue they would be safer than in cars driven by humans because they can’t get distracted or drive when tired. But those surveyed by AAA say they trust their own driving skills. Many feel the technology is too new and unproven. John Nielsen, AAA’s managing director of automotive engineering and repair, said tests suggest drivers may be overestimating their own abilities. He also believes they will be more likely to trust self-driving cars as they become more familiar with features such as automatic braking or parking. He estimated that the “comfort level” will increase in five to ten years.1. What is the finding of the AAA survey?2. What does John Nielsen say about self-driving cars?Questions 3 and 4 are based on the news report you have just heard.One dog has been killed and multiple dogs have been injured by a snowmobile driver in what appears to be an intentional attack on competitors in the Iditarod Race in Alaska. Aliy Zirkle was the first to report an attack. A snowmobile driver had “repeatedly attempted to harm her and her team,” and one of Zirkle’s dogs had received a non-life-threatening injury. Zirkle reported the attack when she arrived in Nulato, Alaska, in the early hour of the morning. Then Jeff King, a four-time champion reported a similar attack. His team was hit by a snowmobile driver, injuring several dogs and killing a 3-year-old male dog.Reporter Zachariah Hughe says that neither King nor Zirkle was injured. Although this incident very much alters the race of the two participants competing for a win, both are going to continue on their way toward the finish line.Alaska State Troopers released a statement saying they’ve arrested Arnold Demoski, 26. He faces trial on several charges.3. What is the news report mainly about?4. What do we learn about Jeff King?Questions 5 to 7 are based on the news report you have just heard.A tour boat turned over off the coast of Nicaragua, killing at least 13 people and leaving more passengers missing, officials said.The boat was carrying 32 people -- 25 Costa Ricans, 4 Americans and 3 Nicaraguans. The 13 dead were all Costa Rican, the foreign ministry said. The boat, traveling between Nicaragua’s Big Corn Island and Little Corn Island, turned over Saturday near the larger island.Some passengers remain missing, the Costa Rican foreign ministry said, but did not specify how many. A local radio said an unspecified number of people were rescued, including the tour boat’s owner, Hilario Blandon.Nicaraguan naval authorities had banned sea travel in the area because of bad weather and strong winds, but the tour boat proceeded anyway. Blandon, the boat’s owner, has been arrested by Nicaraguan authorities, the state-run news agency said. Both he and a crew member are being investigated for unintentional murder and exposing people to danger, according to police.5. What happened to the tour boat sailing off the Nicaraguan coast?6. How many people was the boat sailing?7. What do we know about the owner of the boat?Section BQuestions 8 to 11 are based on the conversation you have just heard.M: Hi, Susan, you are looking very smart today.W: I always look smart, James. Actually, I’m on my way to a job interview.M: What job? Oh, you mean for the summer holidays?W: Yeah, there’s only two weeks to go. I’ve got a second interview with that big foreign accountancy firm in the city center. You know the one.M: That’s fantastic!W: The work is just helping out with data input. You know, but the pay isn’t too bad. It might suit you too. I know they have at least two temporary positions available. And I don’t think they have anyone else yet.M: Um, if they take you on, tell them you know a friend who’d be really good too. I really need the money and the experience will look good on my resume. Maybe we’ll be working together --the dream team!W: Ok, we’ll do. If the boss likes me, I’ll mention it. It will be good to have someone around who I know. I’ll phone you afterwards. But perhaps you should put in an application anyway.M: Thanks Susan, that’s great. Listen, do you want a lift to the city? I have my dad’s car today and nothing else to do this morning.W: Sure, thanks James.M: Let’s go then. The car is over there.W: By the way, how is your knowledge of accountancy? The interviewer may ask you about it. M: No problem. I think I can survive. I might just have to review a few accountancy terms. Maybe you can give me a practice interview first.W: Of course, let’s go then. Don’t want to be late.8. Where will Susan probably get a job?9. What will Susan’s future job involve?10.

And when it comes to everyday technology skills, we are dead last when compared to other developed countries. Here’s Gabriel Emanuel of National Public Radio.M: Let’s start with the bad news that Americans are terrible at technology skills -- using email, naming the file on a computer, using the link on a webpage or just texting someone.W: No country scored below the U.S.?M: Only one country. Poland performed as poorly as we did. Who came out the first? Japan did the best, and then Finland. If you look at data about reading and math, you’ll notice something interesting. Young adults who went to college or graduate school were doing pretty well. In literacy, they were actually doing better than their peers in other countries.W: So that’s a bit of good news.M: But when you look at Americans who have a high school diploma, they look a lot like other countries’ high school dropouts. We have a lot of work to do. That is especially true, when it comes to math. You go to the store and there is a sale. Buy one; get the second one half off. You decide to buy two. How much do you pay?W: You mean high school graduates can’t do this task in general?M: You are right. What does that tell us about our education system? Well, it tells us that we need to think about the preparedness of our students, as they are leaving high school.W: Right. And schools, employers, in fact, we all need to do something about it. Thank you, Gabrielle.12. What does the man say about Americans?13. Who performed the best in technology skills according to the man?14. In what aspect did American college students perform well?15.

Like apples, carrots are native to Central Asia. That’s why horses, which also come from Central Asia, like both apples and carrots so much.With wild carrots, the roots are white, small and skinny, so you’d have to pick a lot of wild carrots to get enough to eat. Doctors used carrot seeds and roots as medicine on the theory that foods that taste bad must be good for you.Around 800 AD, people in Central Asia managed to develop a new kind of carrot -- a purple carrot that attracted more interest from international traders. Then in the late 1500s, food scientists in the Netherlands cultivated large, straight, sweet, red carrots like the ones we eat today. But people still mostly fed carrots to horses, donkeys and pigs, and didn’t eat them themselves.In the 1600s, people in China used carrots as medicine, but they also ate carrots boiled in soup. The red color was popular for Chinese New Year celebrations.But carrots got their biggest boost during the two World Wars when food shortages forced people to eat them, and governments told everyone how healthy carrots were. Today, cooler countries grow most of the world’s carrots. Machines do most of the planting and picking, and carrots are easy to store and ship, so they are cheap almost everywhere.16. What do we learn from the talk about wild carrots?17. What does the speaker say about carrots in the late 1500s?18. Why did people turn to carrots for food during the two world wars?Questions 19 to 21 are based on the passage you have just heard.Katherine loved Facebook. With Facebook, she could stay connected with her family no matter how far away they were. She could see their photos and read their status updates. With Facebook, she could keep her relatives up-to-date on what she was doing.Another thing Katherine loved about Facebook was that she didn’t have to think about time zones when updating family. Whenever she called her parents or other relatives, she always had to think about the time difference so that she wouldn’t wake someone up or call when she knew they were in church. Facebook was so convenient.When Catherine joined Facebook, some of her classmates at high school started to add her as a friend. At first, this didn’t bother her. She loved learning about the success of people she knew when she was just a teenager. She loved finding out people were getting married, having babies and travelling.Soon however, Katherine found herself comparing herself with the people she was reading about on Facebook. It began to make her feel bad that some people seem to be doing so much better than she was. She was also spending a lot of time on Facebook. It took a lot of time and energy to keep up with everyone’s status updates.Katherine started to think. She looked at the list of over 500 friends she had on Facebook and realized some of them were not really friends at all.19. What was one particular convenience Katherine loved of Facebook?20. How did Katherine feel when her classmates added her as a Facebook friend?21. What made Katherine feel bad about herself later on?Questions 22 to 25 are based on the passage you have just heard.Do you know where a mule comes from? It is the child of a donkey and a horse.Mules have strong muscles like horses but they eat less, can work longer, and are gentler like donkeys.George Washington was the first person in the United States to own mules. He had heard that mules made good farm animals and he contacted the U.S. ambassador in Spain to ask about them. In 1785, King Charles III of Spain sent Washington a male donkey as a gift. That male donkey became the father of the mule industry in the U.S.Every April, Maury County holds a Mule Day celebration. Held in Columbia, Tennessee, Mule Day had its beginnings as “Breeder’s Day” in the 1840s. Farmers and farm animal breeders would bring their animals to market every April to show, buy and trade. This was an important business before the days of tractors when many families made a living from farming, and mules were used as work animals. Eventually, tractors began to replace mules, making them less in demand.A parade was added to Mule Day in 1934 to attract more people. Over the years, other activities have been added. And today more than 200,000 people show up each year to watch and participate.

The word “yellow” describes the color of the muddy water in the Yellow River. Originating in Qinghai province, it flows through nine provinces and finally flows into the Bohai Sea. Yellow is one of several rivers which Chinese people rely on for existence. The river basin of the Yellow River was both the birthplace of ancient Chinese civilization and the most prosperous region in early Chinese history. However, due to frequent devastating floods, the Yellow once caused a number of disasters. Over the last decades, the government has taken plenty of measures to prevent disasters.。

Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once. The method for making beer has changed over time. Hops (啤酒花），for example, which give many a modern beer its bitter flavor, are a26 recent addition to the beverage. This was f1ISt mentioned in reference to brewing in the ninth century. Now, researchers have found a 27 ingredient in residue (残留物）from 5 , 000-year-old beer brewing equipment. While digging two pits at a site in the central plains of China , scientists discovered fragments from pots and vessels. The different shapes of the containers 28 they were used to brew, filter, and store beer. They may be ancient "beer-making tools," and the earliest29 evidence of beer brewing in China, the researchers reported in the Proceedings of the National Academy of Sciences. To30 that theory, the team examined the yellowish, dried 31 inside the vessels. The majority of the grains, about 80% , were from cereal crops like barley (⼤麦），and about 10% were bits of roots, 32lily, which would have made the beer sweeter, the scientists say. Barley was an unexpected find: the crop was domesticated in Western Eurasia and didn't become a —33 food in central China until about 2,000 years ago, according to the researchers. Based on that timing, they indicate barley may have 34 in the region not as food, but as35 material for beer brewing.

Each statement contains 叫o rmation given in one of the paragraphs. Identify the paragraph from咖ch the information is derived.You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questionsby marking the corresponding letter on Answer Sheet 2.The Blessing and Curse of the People who Never ForgetA handful of people can recall al叩st every day of their lives in enormous detail—and after years of research , neuroscientists are finally beginning to understand how they do it.A)For most of us, memory is a mess of blurred and faded pictures of our lives. As much as we would like to clingon to our past, even the saddest moments can be washed away with time.B)Ask Nima Veiseh what he was doing for any day in the past 15 years, however, and he will give you the detailsof the weather, what he was wearing, or even what side of the train he was sitting on his journey to work. "My memory is like a library of video tapes, walk-throughs of every day of my life from waking to sleeping," he explains.C)V e iseh can even put a date on when those tapes started recording :15 December 2000 ,when he met his fastgirlfriend at his best friend's 16th birthday party. He had always had a good memory, but the thrill of young love seems to have shifted a gear in his mind :from now on, he would start recording his whole life in detail. " I could tell you everything about every day after that. "D)Needless to say, people like Veiseh are of great interest to neuroscientists (神经科学专家）hoping to understandthe way the brain records our lives. A couple of recent papers have finally opened a window on these people's extraordinary minds. And such research might even suggest ways for us all to relive our past with greater clarity.E)"Highly superior autobiographical memory" (or HSAM for short) , first came to light in the early 2000s, with ayoung woman named Jill Price. E-mailing the neuroscientist and memory researcher Jim McGaugh one day, she 迦med that she could recall every day of her life since the age of 12. Could he help explain her experiences?F)McGaugh invited her to his lab, and began to test her: he would give her a date and ask her to tell him about theworld events on that day. True to her word, she was correct almost every time.G)It didn't take long for magazines and documentary film-makers to come to understand her "total recall," andthanks to the subsequent media interest, a few dozen other subjects (including V e iseh) have since come forward and contacted the team at the University of California, Irvine.H)Interestingly, their memories are highly self-centred: although they can remember "autobiographical" life eventsin extraordinary detail, they seem to be no better than average at recalling impersonal information, such as random (任意选取的）lists of words. Nor are they necessarily better at remembering a round of drinks, say.And although their memories are vast, they are still likely to suffer from "false memories. " Clearly, there is no such thing as a "perfect" memory—their extraordinary minds are still using the same flawed tools that the rest of us rely on. The question is, how?I)Lawrence Patihis at the University of Southern Mississippi recently studied around 20 people with HSAM and found that they scored particularly high on two measures: fantasy proneness (倾向）and absorption. Fantasy proneness could be considered a tendency to imagine and daydream, whereas absorption is the tendency to allow your mind to become fully absorbed in an activity—to pay complete attention to the sensations (感受）and the experiences. "I'm extremely sensitive to sounds, smells and visual detail," explains Nicole Donohue, who has taken part in many of these studies. "I definitely feel things more strongly than the average person. "J)The absorption helps them to establish strong foundations for recollection, says Patihis , and the fantasy proneness means that they revisit those memories again and again in the coming weeks and months. Each time this initial memory trace is "replayed, "it becomes even stronger. In some ways, you probably go through that process aftera big event like your wedding day—but the difference is that thanks to their other psychological tendencies, theHSAM subjects are doing it day in, day out, for the whole of their lives.K)Not everyone with a tendency to fantasise will develop HSAM, though, so Patihis suggests that something must have caused them to think so much about their past. "Maybe some experience in their childhood meant that they became obsessed (着迷）with calendars and what happened to them," says Patihis.L)The people with HSAM I've interviewed would certainly agree that it can be a mixed blessing. On the plus side, it allows you to relive the most transformative and enriching experiences. Veiseh, for instance, travelled a lot in his youth. In his spare time ,he visited the local art galleries ,and the paintings are now lodged deep in his autobiographical memories.M)" I magine being able to remember every painting, on every wall, in every gallery space, between nearly 40 countries," he says. "That's a big education in art by itself. " With this comprehensive knowledge of the history of art, he has since become a professional painter.N) Donohue, now a history teacher, agrees that it helped during certain parts of her education: "I can definitely remember what I learned on certain days at school. I could imagine what the teacher was saying or what it looked like in the book. " 0)Not everyone with HSAM has experienced these benefits, however. Viewing the past in high definition can makeit very difficult to get over pain and regret. " It can be very hard to forget embarrassing moments, "says Donohue. "You feel the same emotions—it is just as raw, just as fresh…You can't turn off that stream of memories ,no matter how hard you try. " V eiseh agrees :"It is like having these open wounds—they are just a part of you, "he says.P)This means they often have to make a special effort to lay the past to rest. Bill, for instance, often gets painful " fl ashbacks ,"in which unwanted memories intrude into his consciousness ,but overall he has chosen to see it as the best way of avoiding repeating the same mistakes. "Some people are absorbed in the past but not open to new memories, but that's not the case for me. I look forward to each day and experiencing something new. "36.People with HSAM have the same memory as ordinary people when it comes to impersonal information.37.Fantasy proneness will not necessarily cause people to develop HSAM.38.Veiseh began to remember the details of his everyday experiences after he met his first young love.39.Many more people with HSAM started to contact researchers due to the mass media.40.People with HSAM often have to make efforts to avoid focusing on the past.41.Most people do not have clear memories of past events.42.HSAM can be both a curse and a blessing.43.A young woman sought explanation from a brain scientist when she noticed her unusual memory.44.Some people with HSAM find it very hard to get rid of unpleasant memories.45.A recent study of people with HSAM reveals that they are liable to fantasy and full absorption in an activity. Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice andmark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.The phrase almost completes itself: midlife crisis. It's the stage in the middle of the journey when people feel youth vanishing, their prospects narrowing and death approaching.There's only one problem with the cliche (套话）. It isn't true." I n fact ,there is almost no hard evidence for midlife crisis other than a few small pilot studies conducted decades ago, " Barbara Hagerty writes in her new book, Life Reimagined. The bulk of the research shows that there may be a pause, or a shifting of gears in the 40s or 50s, but this shift "can be exciting, rather than terrifying. "Barbara Hagerty looks at some of the features of people who turn midlife into a rebirth. They break routines , because "autopilot is death. " They choose purpose over happiness—having a clear sense of purpose even reduces the risk of Alzheimer's disease. They give priority to relationships, as careers often recede (逐渐淡化）．Life Reimagined paints a picture of middle age that is far from gloomy. Midlife seems like the second big phase of decision-making. Your identity has been formed; you've built up your resources; and now you have the chance to take the big risks precisely because your foundation is already secure.Karl Barth described midlife precisely this way. At middle age, he wrote, "the sowing is behind; now is the time to reap. The run has been taken; now is the time to leap. Preparation has been made; now is the time for the venture of the work itself. "The middle-aged person, Barth continued, can see death in the distance, but moves with a "measured haste" to get big new things done while there is still time.What Barth wrote decades ago is even truer today. People are healthy and energetic longer. We have presidential candidates running for their frrst term in office at age 68, 69 and 74. A longer lifespan is changing the narrative structure of life itself. What could have been considered the beginning of a descent is now a potential turning point—the turning point you are most equipped to take full advantage of.46.What does the author think of the phrase " m idlife crisis" ?A)It has led to a lot of debate.B)It is widely acknowledged.C)It is no longer fashionable.47.How does Barbara Hagerty view midlife?A)It may be the beginning of a crisis.B)It can be a new phase of one's life.C)It can be terrifying for the unprepared.D)It may see old-age diseases approaching.48.How is midlife pictured in the book Life Reimagined?A)It can be quite rosy.C)It undergoes radical transformation.49.According to Karl Barth, midlife is the time.A)to relaxC)to harvest50.What does the author say about midlife today?A)It is more meaningful than other stages of life.B)It is likely to change the narrative of one's life.C)It is more important to those with a longer lifespan.D)It is likely to be a critical turning point in one's life.D)It misrepresents real life.B)It can be burdensome.D)It makes for the best part of one's life.B)to matureD)to reflectPassage TwoQuestions 51 to 55 are based on the following passage.In spring, chickens start laying again, bringing a welcome source of protein at winter's end. So it's no surprise that cultures around the world celebrate spring by honoring the egg.Some traditions are simple, like the red eggs that get baked into Greek Easter breads. Others elevate the egg into a fancy art, like the heavily jewel-covered "eggs" that were favored by the Russians starting in the 19th century.One ancient form of egg art comes to us from Ukraine. For centuries, U阮inians have been drawing complicated patterns on eggs. Contemporary artists have followed this tradition to create eggs that speak to the anxieties of our age: Life is precious, and delicate. Eggs are, too."There's something about their delicate nature that appeals to me," says New Yorker cartoonist Roz Chast. Several years ago , she became interested in eggs and learned the traditional Ukrainian technique to draw her very modem characters."I've broken eggs at every stage of the process—from the very beginning to the very ,very end."But there's an appeal in that vulnerability. "There's part of this sickening horror of knowing you're walking on the edge with this, that I kind of like, knowing that it could all fall apart at any second. "Chast's designs , such as a worried man alone in a tiny rowboat, reflect that delicateness.Traditional Ukrainian decorated eggs also spoke to those fears. The elaborate patterns were believed to offer protection against evil."There's an ancient legend that as long as these eggs are made, evil will not prevail in the world," says Joan Brander, a Canadian egg-painter who has been painting eggs for over 60 years, having learned the art from her Ukrainian relatives. The tradition, dating back to 300 B. C. ,was later incorporated into the Christian church. The old symbols, however, stillendure. A decorated egg with a bird on it, given to a young married couple, is a wish for children. A decorated egg thrown into the field would be a wish for a good harvest.51. W hy do people in many cultures prize the egg?A)It is a welcome sign of the coming of spring.B)It is their major source of protein in winter.C)It can easily be made into a work of art.D)It can bring wealth and honor to them.52. W hat do we learn about the decorated "eggs" in Russia?A)They are shaped like jewel cases.B)They are cherished by the rich.C)They are heavily painted in red.D)They are favored as a form of art.53. W hy have contemporary artists continued the egg art tradition?A)Eggs serve as an enduring symbol of new life.B)Eggs have an oval shape appealing to artists.C)Eggs reflect the anxieties of people today.D)Eggs provide a unique surface to paint on.54. W hy does Chast enjoy the process of decorating eggs?A)She never knows if the egg will break before the design is completed.B)She can add multiple details to the design to communicate her idea.C)She always derives great pleasure from designing something new.D)She is never sure what the final design will look like until the end.55.What do we learn from the passage about egg-painting?A)It originated in the eastern part of Europe.B)It has a history of over two thousand years.C)It is the most time-honored form of fancy art.D)It is especially favored as a church decoration.Part IV Translation (30 minutes)Directions : 的r this part, you are allowed 30 minutes to translate a passage from Chinese into English. You should write your answer on Answer Sheet 2.珠江是华南⼀⼤河系，流经⼴州市，是中国第三长的河流，仅次于长江和黄河。

2017六月四级真题及参考答案解析大学英语四级考试(CET-4)是检验大学英语教学的重要手段，2017年四级六月考试刚刚结束，不少考生都想知道2017六月四级真题及答案的内容，希望能够帮到您。

2017六月四级真题及答案大学英语四级阅读真题原文Passage OneQuestions 56 to 60 are based on the following passage.Across the rich world, well-educated people increasingly work longer than the less-skilled. Some 65% of American men aged 62-74 with a professional degree are in the workforce, compared with 32% of men with only a high-school certificate. This gap is part of a deepening divide between the well-educated well-off and the unskilled poor. Rapid technological advance has raised the incomes of the highly skilled while squeezing those of the unskilled. The consequences, for individuals and society, are profound.The world is facing an astonishing rise in the number of old people. And they will live longer than ever before. Over the next 20 years the global population of those aged 65 or more will almost double, from 600 million to 1.1 billion. The experience of the 20th century, when greater longevity (长寿) translated into more years in retirement rather than more years at work, has persuaded many observers that this shift will lead to slower economic growth, while the swelling ranks of pensioners will create government budget problems.But the notion of a sharp division between the working young and the idle old misses a new trend, the growing gap between the skilled and the unskilled. Employment rates arefalling among younger unskilled people, whereas older skilled folk are working longer. The divide is most extreme in America, where well-educated baby-boomers (二战后生育高峰期出生的美国人) are putting off retirement while many less-skilled younger people have dropped out of the workforce.Policy is partly responsible. Many European governments have abandoned policies that used to encourage people to retire early. Rising life expectancy(预期寿命), combined with the replacement of generous defined-benefit pension plans with less generous defined-contribution ones, means that even the better-off must work longer to have a comfortable retirement. But the changing nature of work also plays a big role. Pay has risen sharply for the highly educated, and those people continue to reap rich rewards into old age because these days the educated elderly are more productive than the preceding generation. Technological change may well reinforce that shift: the skills that complement computers, from management knowhow to creativity, do not necessarily decline with age.大学英语四级阅读题目注意：此部分试题请在答题卡2上作答。
