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. I had a really good stay here, and I'd like to recommend your hotel to my friends and colleagues.W: That’s very kind of you. Thank you again for staying at Sheraton Hotel.8.

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.

The nine largest cities in the Pearl River Delta have a total population of over 57 million. Since the reform and opening up in the late 1970s, the Pearl River Delta has become one of the major economic regions and manufacturing centers in China and around the world.Part II Listening Comprehension听力原文Section AQuestions 1 and 2 are based on the news report you have just heard.Automakers and tech companies are working hard to offer the first true self-driving car, but 75% of drivers say they wouldn’t feel safe in such a vehicle. 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. Why does James want the job in that company?11. What does James say he would have to do to prepare for the interview?Questions 12 to 15 are based on the conversation you have just heard.W: There is new data out today that confirms that many Americans are not good at Math. 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. What do we learn from the conversation about American high school education?Section CQuestions 16 to 18 are based on the passage you have just heard.Wild carrots probably evolved with the other flowering plants about 360 million years ago. 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. If you visit during Mule Day celebrations, you might see mule-driving contests, square dances, horn shows, or even tree-cutting competitions.22. What does the speaker say about mules?23. What do we learn about the donkey which is said to be the father of the US mule industry?24. What did farmers usually do on Mule day in the 1840s?25. What made mules less in demand in America?2017年6月大学英语四级考试真题听力原文及参考答案（第３套）Part I WritingComputer for SaleAs I am about to graduate and leave the campus, I am going to sell my personal laptop at a low price.It is a Lenovo ThinkPad that I bought in June, 2015.

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.

Passage OneIf 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 periodI’ve already lived—the 1960s.I was in my twentiesand everything was being renewed.People were coming out ofa formal and almost Victorian attitude,and you really felt anything was possible.Meeting people was the thing,and you went to coffee barswhere you met friends and spent the evening.The cinema, the theater...all that was very excitingwith 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 timeordinary people started going out to eat.We were beginning to be adventurous about food, but we were more interested in meeting peoplethan in eating or drinking.And dress, yes,that was the revolution.I mean girls went around in really short skirtsand 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 ageyou 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.Questions 16 to 18 are based on the passageyou have just heard.16. Why does the speaker sayhe would like to relive the 1960s?17. What does the speaker saywas the most popular thing to do at that time?18. What do we learn about the speaker?Passage TwoDogs, man’s best friends,have a clear strategy for dealing with angry owners—they look away.New research showsthat dogs limit their eye contact with angry humans. The scientists suggestthis may be an attempt to calm humans down.This behavior may have evolvedas dogs gradually learned they could benefitfrom 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 humanswere 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 mostat the eyes of humansand other dogs to sense their emotions.When dogs looked at the 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 signsfrom 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 facesas a whole to sense how people are feeling,instead of focusing on a given feature.They suggest this indicates thatdogs aren’t sensing emotions from a single feature, but piecing together informationfrom all facial features just as humans do. Questions 19 to 21 are based on the passageyou have just heard.19. What do dogs dowhen they are faced with angry humans?20. What does a dog dowhen it sees the expressions of angry dogs?21. How does a dog sense people’s feelings? Passage ThreeWinter 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 housesand have learned to adapt.What do animals do?There are three main waysthat 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 dropsand their heart beat slows down.To prepare for this before winter,these animals eat extra food to become fatwhich gives them the energy they needwhile 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 the 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 wayto the distant south.Some birds fly in groups for safety,while others fly alone.Questions 22 to 25 are based on the passageyou have just heard.22. What does the speaker sayabout animals in winter?23. What do we learnabout animals that sleep through winter?24. How do animals like miceadapt to the severe winter?25. Why do some birds fly in groups for migrating according to the speaker?This is the end of listening comprehension.。

DCBAC听力原文News Report OneAutomakers and tech companies are working hard to offer the first true self-driving car, but 75% of drivers say they wouldn’t feel safe in such a vehicle. Still, 60% of 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 (Triple A) survey of 1,800 drivers.Advocates of self-driving cars argue they would be safer than cars driven by humans because they wouldn’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 considerably in five to ten years.1.What is the finding of the AAA survey?2.What does John Nielsen say about self-driving cars?News Report TwoOne 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 hours 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 Hughes 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 finishingline.Alaska State Troopers released a statement saying they’ve arrested Arnold Demoski, 26. He faces a trial on several charges.3.What is the news report mainly about?4.What do we learn about Jeff King?News Report ThreeA 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, four Americans and three 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. 7Both 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 carrying?7. What do we know about the owner of the boat?Section BConversation OneM: Hi, Susan! You’re 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 is 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 the data input, you know, but the pay isn’t too bad. It might suit you too. I know they hav e released 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. 11I might just have to review a few accountancy terms. Maybe you can give me a practicing 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. Why did James want the job in that company?11. What did James say he’ll have to do to prepare for the interview?Conversation TwoW: There is new data out today the confirms that many Americans are not good at math. And when it comes to everyday technology skills, we are did last compared to other developed countries. Here is Gabriele Emannuel of National Public Radio.M: Let’s start with the bad news that Americans are terr ible at technology skills, using email, naming a file on the computer, using the link on a webpage or just texting someone.W: No country scored below the US.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 the peers in any 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’s 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 you pay?W: You mean high school graduates cannot 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, Gabriele.12. What does the man say about Americans?13. Who performs the best in technology skills according to the man?14. In what aspect did American college students perform well?15. What do we learn from the conversation about American high school education?Section CPassage OneWild carrots probably evolved with the other flowering plants, about 360 million years ago. 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 we 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—thatattracted 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 1600, 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 force people to eat them, and governments told everyone how healthy carrots were. Today, cooler countries grow most of the world’s carrots. Mac hines 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?Passage TwoKatherine 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 Katherine 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 traveling. 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 seemed 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.

How did Katherine feel when her classmates added her as a Facebook friend?21. What made Katherine feel bad about herself later on?Passage ThreeDo 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 US 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 US.Every April, Maury County holds a Mule Day celebration. Held in Columbia, Tennessee, Mule Day had its beginning as “Breeders’ 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 beenadded, and today more than 200,000 people show up each year to watch and participate. If you visit the Mule Day celebrations, you might see mule-driving contests, square dances or shows, or even a lumberjack competitions.22. What does the speaker say about mules?23. What do we learn about the donkey which is said to be the father of the US mule industry?24. What did farmers usually do on Mule Day in the 1840s?25. What made mules less in demand in America?【参考译文】The Pearl River, an extensive river system in southern China, flows through Guangzhou City.

Fear not, however, for coffee can stimulate them again. During 26 exercise, our muscles tire as they run out of fuel and build up waste products. Muscle performance can also be affected by a 27 called “central fatigue,” in which an imbalance in the body's chemical messengers prevents the central nervous system from directing muscle movements 28 . It was not known, however, whether central fatigue might also affect motor systems not directly 29 in the exercise itself, such as those that move the eyes. To find out, researchers gave 11 volunteer cyclists a carbohydrate (碳水化合物的) 30 either with a moderate dose of caffeine (咖啡因), which is known to stimulate the central nervous system, or as a placebo (安慰剂) without, during 3 hours of 31 . After exercising, the scientists tested the cyclists with eye-tracking cameras to see how well their brains could still 32 their visual system. The team found that exercise reduced the speed of rapid eye movements by about 8%, 33 their ability to capture new visual information. The caffeine, the equivalent of two strong cups of coffee, was 34 to reverse this effect, with some cyclists even displaying 35 eye movement speeds. So it might be a good idea to get someone else to drive you home after that marathon.A) cautiouslyB) commitC) controlD) cyclingE) effectivelyF) increasedG) involvedH) limited I) phenomenon J) preventing K) sensitive L) slowing M) solution N) sufficient O) vigorousSection BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Team spiritA) Teams have become the basic building blocks of organisations. Recruitment advertisements routinely call for “team players”. Business schools grade their students in part on their performance in group projects. Office managers knock down walls to encourage team building.Teams are as old as civilisation, of course: even Jesus had 12 co-workers. But a new report by Deloitte, “Global Human Capital Trends”, based on a survey of more than 7,000 executives in over 130 countries, suggests that the fashion for teamwork has reached a new high. Almost half of those surveyed said their companies were either in the middle of restructuring or about to embark on (开始) it; and for the most part, restructuring meant putting more emphasis on teams.B) Companies are abandoning conventional functional departments and organising employees into cross-disciplinary teams that focus on particular products, problems or customers. These teams are gaining more power to run their own affairs. They are also spending more time working with each other rather than reporting upwards. Deloitte argues that a new organisational form is on the rise: a network of teams is replacing the conventional hierarchy (等级体制).C) The fashion for teams is driven by a sense that the old way of organising people is too rigid for both the modern marketplace and the expectations of employees. Technological innovation places greater value on agility (灵活性). John Chambers, chairman of Cisco Systems Inc., a worldwide leader in electronics products, says that “we compete against market transitions (过渡), not competitors. Product transitions used to take five or seven years; now they take one or two.” Digital technology also makes it easier for people to co-ordinate their activities without resorting to hierarchy. The “millennials” (千禧一代) who will soon make up half the workforce in rich countries were raised from nursery school onwards to work in groups.D) The fashion for teams is also spreading from the usual corporate suspects (such as GE and IBM) to some more unusual ones. The Cleveland Clinic, a hospital operator, has reorganised its medical staff into teams to focus on particular treatment areas; consultants, nurses and others collaborate closely instead of being separated by speciality (专业) and rank. The US Army has gone the same way. In his book, Team of Teams, General Stanley McChrystal describes how the army's hierarchical structure hindered its operations during the early stages of the Iraq war. His solution was to learn something from the rebels it was fighting: decentralising authority to self-organising teams.E) A good rule of thumb is that as soon as generals and hospital administrators jump on a management bandwagon (追随一种管理潮流), it is time to ask questions. Leigh Thompson of Kellogg School of Management in Illinois warns that, “Teams are not always the answer – teams may provide insight, creativity and knowledge in a way that a person working independently cannot; but teamwork may also lead to confusion, delay and poor decision-making.” The late Richard Hackman of Harvard University once argued, “I have no question that when you have a team, the possibility exists that it will generate magic, producing something extraordinary...But don't count on it.”F) Hackman (who died in 2013) noted that teams are hindered by problems of co-ordination and motivation that chip away at the benefits of collaboration. High-flyers (能干的人) who are forced to work in teams may be undervalued and free-riders empowered. Group-think may be unavoidable. In a study of 120 teams of senior executives, he discovered that less than 10% of their supposed members agreed on who exactly was on the team. If it is hard enough to define a team's membership, agreeing on its purpose is harder still.G) Profound changes in the workforce are making teams trickier to manage. Teams work best if their members have a strong common culture. This is hard to achieve when, as is now the case in many big firms, a large proportion of staff are temporary contractors. Teamwork improves with time: America's National Transportation Safety Board found that 73% of the incidents in itscivil-aviation database occurred on a crew's first day of flying together. However, as Amy Edmondson of Harvard points out, organisations increasingly use “team” as a verb rather than a noun: they form teams for specific purposes and then quickly disband them.H) The least that can be concluded from this research is that companies need to think harder about managing teams. They need to rid their minds of sentimentalism (感情用事): the most successful teams have leaders who are able to set an overall direction and take immediate action. They need to keep teams small and focused: giving in to pressure to be more “inclusive” is a gua rantee of dysfunction. Jeff Bezos, Amazon's boss, says that “If I see more than two pizzas for lunch, the team is too big.” They need to immunise teams against group-think: Hackman argued that the best ones contain “deviants” (离经叛道者) who are willing to do something that may be upsetting to others.I) A new study of 12,000 workers in 17 countries by Steelcase, a furniture-maker which also does consulting, finds that the best way to ensure employees are “engaged” is to give them more control over where and how they do their work – which may mean liberating them from having to do everything in collaboration with others.J) However, organisations need to learn something bigger than how to manage teams better: they need to be in the habit of asking themselves whether teams are the best tools for the job.Team-building skills are in short supply: Deloitte reports that only 12% of the executives they contacted feel they understand the way people work together in networks and only 21% feel confident in their ability to build cross-functional teams. Loosely managed teams can become hotbeds of distraction – employees routinely complain that they can't get their work done because they are forced to spend too much time in meetings or compelled to work in noisy offices. Even in the age of open-plan offices and social networks some work is best left to the individual.36. Successful team leaders know exactly where the team should go and are able to take prompt action.37. Decentralisation of authority was also found to be more effective in military operations.38. In many companies, the conventional form of organisation is giving way to a network of teams.39. Members of poorly managed teams are easily distracted from their work.40. Teamwork is most effective when team members share the same culture.41. According to a report by Deloitte, teamwork is becoming increasingly popular among companies.42. Some team members find it hard to agree on questions like membership and the team's purpose.43. Some scholars think teamwork may not always be reliable, despite its potential to work wonders.44. To ensure employees' commitment, it is advisable to give them more flexibility as to where and how they work.45. Product transitions take much less time now than in the past.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 and mark 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.Shoppers in the UK are spending less money on toilet paper to save money, research has shown.Penny-pinching UK consumers choose cheaper products from discounters such as Aldi and Lidl rather than luxury alternatives.This has wiped 6% off the value of the soft tissue paper market in the UK. It has shrunk from £1.19 billion in 2011 to £1.12 billion in 2015, according to a new report from market research company Mintel. Furthermore, the future of the market looks far from rosy, with sales expected to fall further to £1.11 billion in 2016.In the last year alone, despite an increase in the UK population and a subsequent rise in the number of households, sales of toilet paper fell by 2%, with the average household reducing their toilet roll spending from £43 in 2014 to £41 in 2015.Overall, almost three in five people say they try to limit their usage of paper – including facial tissue and kitchen roll –to save money. “Strength, softness and thickness remain the leading indicators of toilet paper quality, with just a small proportion of consumers preferring more luxurious alternatives, such as those with flower patterns or perfume,” s aid Mintel analyst Jack Duckett. “These extra features are deemed unnecessary by the majority of shoppers, which probably reflects how these types of products are typically more expensive than regular toilet paper, even when on special offer.”While consumers are spending less on toilet paper, they remain fussy – in theory at least –when it comes to paper quality. Top of Britons' toilet paper wish list is softness (57%) followed by strength (45%) and thickness (36%).One in 10 buyers rank toilet rolls made from recycled paper among their top considerations, highlighting how overall the environment is much less of a consideration for shoppers than product quality. In a challenge for manufacturers, 81% of paper product users said they would consider buying recycled toilet tissue if it were comparable in quality to standard paper.46. The market sales of toilet paper have decreased because ______.A) Britons have cut their spending on itB) its prices have gone up over the yearsC) its quality has seen marked improvementD) Britons have developed the habit of saving47. What does the author think of the future of the tissue paper market in the UK?A) It will expand in time.B) It will remain gloomy.C) It will experience ups and downs.D) It will recover as population grows.48. What does Jack Duckett say about toilet paper?A) Special offers would promote its sales.B) Consumers are loyal to certain brands.C) Luxurious features add much to the price.D) Consumers have a variety to choose from.49. What do we learn about Britons concerning toilet paper?A) They are particular about the quality of toilet paper.B) They emphasize the strength of toilet paper the most.C) They prefer cheap toilet paper to recycled toilet paper.D) They reject using toilet paper with unnecessary features.50. What can we infer from the last paragraph?A) More and more Britons buy recycled toilet paper to protect the environment.B) Toilet paper manufacturers are facing a great challenge in promoting its sales.C) Toilet paper manufacturers compete with one another to improve product quality.D) Environmental protection is not much of a concern when Britons buy toilet paper.Passage TwoQuestions 51 to 55 are based on the following passage.“One of the reasons I find this topic ve ry interesting is because my mom was a smoker when I was younger,” says Lindson-Hawley, who studies tobacco and health at the University of Oxford.By studying about 700 adult smokers, she found out that her mom quit the right way – by stopping abruptly and completely.In her study, participants were randomly (随机地) assigned to two groups. One had to quit abruptly on a given day, going from about a pack a day to zero. The other cut down gradually over the course of two weeks. People in both groups used nicotine (尼古丁) patches before they quit, in addition to a second form of nicotine replacement, like gum or spray. They also had talk therapy with a nurse before and after quit day.Six months out, more people who had quit abruptly had stuck with it – more than one-fifth of them, compared to about one-seventh in the other group. Although these numbers appear low, it is much higher than if people try without support.And the quit rates were particularly convincing given that before the study started, most oft he people had said they'd rather cut down gradually before quitting. “If you're training for a marathon, you wouldn't expect to turn up and just be able to run it. And I think people see that for smoking as well. They think, ‘Well, if I gradually reduce, it's like practice,’” says Lindson-Hawley. But that wasn't the case. Instead of giving people practice, the gradual reduction likely gave them cravings (瘾) and withdrawal symptoms before they even reached quit day, which could be why fewer people in that gr oup actually made it to that point. “Regardless of your stated preference, if you're ready to quit, quitting abruptly is more effective,” says Dr. Gabriela Ferreira. “When you can quote a specific number like a fifth of the patients were able to quit, that's compelling. It gives them the encouragement, I think, to really go for it,” Ferreira says.People rarely manage to quit the first time they try. But at least, she says, they can maximize the odds of success.51. What does Lindson-Hawley say about her mother?A) She quit smoking with her daughter's help.B) She succeeded in quitting smoking abruptly.C) She was also a researcher of tobacco and health.D) She studied the smoking patterns of adult smokers.52. What kind of support did smokers receive to quit smoking in Lindson-Hawley's study?A) They were given physical training.B) They were looked after by physicians.C) They were encouraged by psychologists.D) They were offered nicotine replacements.53. How does Dr. Gabriela Ferreira view the result of Lindson-Hawley's experiment?A) It is idealized.B) It is unexpected.C) It is encouraging.D) It is misleading.54. The idea of “a marathon” (Line 2, Para.5) illustrates the popular belief that quitting smoking ______.A) is something few can accomplishB) needs some practice firstC) requires a lot of patienceD) is a challenge at the beginning55. What happens when people try to quit smoking gradually?A) They find it even more difficult.B) They are simply unable to make it.C) They show fewer withdrawal symptoms.D) They feel much less pain in the process.Part IV TranslationDirections: For this part, you are allowed 30 minutes to translate a passage from Chinese into English. You should write your answer on Answer Sheet 2.长江是亚洲最长、世界上第三长的河流。

Passage OneIf 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 periodI’ve already lived—the 1960s.I was in my twentiesand everything was being renewed.People were coming out ofa formal and almost Victorian attitude,and you really felt anything was possible.Meeting people was the thing,and you went to coffee barswhere you met friends and spent the evening.The cinema, the theater...all that was very excitingwith 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 timeordinary people started going out to eat.We were beginning to be adventurous about food, but we were more interested in meeting peoplethan in eating or drinking.And dress, yes,that was the revolution.I mean girls went around in really short skirtsand 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 ageyou 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.Questions 16 to 18 are based on the passageyou have just heard.16.

Dogs in the study looked mostat the eyes of humansand other dogs to sense their emotions.When dogs looked at the 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 signsfrom 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 facesas a whole to sense how people are feeling,instead of focusing on a given feature.They suggest this indicates thatdogs aren’t sensing emotions from a single feature, but piecing together informationfrom all facial features just as humans do. Questions 19 to 21 are based on the passageyou have just heard.19. What do dogs dowhen they are faced with angry humans?20. What does a dog dowhen it sees the expressions of angry dogs?21.

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 wayto the distant south.Some birds fly in groups for safety,while others fly alone.Questions 22 to 25 are based on the passageyou have just heard.22. What does the speaker sayabout animals in winter?23. What do we learnabout animals that sleep through winter?24. How do animals like miceadapt to the severe winter?25.

2017年6月大学英语四级考试真题第一套听力2017年6月大学英语四级真题答案(第一套) 翻译：黄河是亚洲第三、世界第六长的河流。

“黄”这个字描述的是其河水浑浊的颜色。

黄河发源于青海，流经九个省份，最后注入渤海。

黄河是中国赖以生存的几条河流之一。

黄河流域(river basin)是中国古代文明的诞生地，也是中国早期历史上最繁荣的地区。

然而，由于极具破坏力的洪水频发，黄河曾造成多次灾害。

在过去几十年里，政府采取了各种措施防止灾害发生。

The Yellow River ranks the third longest in Asia and the sixth longest in the world. The word “yellow”describes the muddy water of the river. The Yellow River，one of several rivers for China to live on，originates from Qinghai，flows through nine provinces, and finally pours into the Bohai Sea. The river basin is not only the birthplace of ancient Chinese civilization，but also the most prosperous region in the early history of China. However,due to the frequent devastating floods, it has caused many disasters. In the past few decades,the government has taken various measures to prevent disasters. 听力：SectionA News 1 B The test driver madea wrong judgement 2 D They have generally done quite well.3 A He works at a national park.4 B They were making a lot of noise.5 A The discovery of a new species of snake.6 C A snake crawled onto his head in his sleep.7 D From its colour.

SectionC Passage Passage1 16 C Everything seemed to be changing. 17 A Meeting people.18 D He was a young student in the 1960s. Passage2 19 B They avoid looking at them. 20 C It focuses its eyes on their mouths. 21 B By taking in their facial expressions as a whole. Passage3 22 D They resort to different means to survive the bitter cold. 23 C They consume the energy stored before the long sleep.24 A By storing enough food beforehand 25 C To stay safe 选词填空部分：26.O vigorous 27.I phenomenon 28.E effectively 29.G involved 30.M solution 31.D cycling 32.C control 33. J preventing 34. N sufficient 35. F increased 【原文】As if you needed another reason to hate the gym, it now turns out that exercise can exhaust not only your muscles, but also your eyes. Fear not, however, for coffee can perk them right up again. During vigorous exercise, our muscles tire as they run out of fuel and build up waste products. Muscle performance can also be affected by a phenomenon called “central fatigue,” in which animbalance in the body’s chemical messengers prevents the central nervous system from directing muscle movements effectively. It was not known, however, whether central fatigue might also affect motor systems not directly involved in the exercise itself—such as those that move the eyes. To find out, researchers gave 11 volunteers a carbohydrate solution either with a moderate dose of caffeine—which is known to stimulate the central nervous system—or as a placebo without, during 3 hours of cycling. After exercising, the scientists tested the cyclists with eye-tracking cameras to see how well their brains could still control their visual system. The team found that exercise reduced the speed of rapid eye movements by about 8%, preventing their ability to capture new visual information. The caffeine—the equivalent of two strong cups of coffee—was sufficient to counteract this effect, with some cyclists even displaying increased eye movement speeds, the team reports today in Scientific Reports. So it might be a good idea to get someone else to drive you home after that marathon. 段落信息匹配：36 [H] 题干：Successful team leaders know exactly where the team should go and are able to take promptaction. 37 [D] 题干：Decentralisation of authority was also found to be more effective in military operations. 38 [B] 题干：In many companies,the conventional form of organisation is giving way to a network of teams.39 [J] 题干：Members of poorly managed teams are easily distractedfrom their work. 40 [G] 题干：Teamwork is most effective when team members share the same culture. 41 [A] 题干：According to a report by Deloitte,teamwork is becoming increasingly popular among companies. 42 [F] 题干：Some team members find it hard to agree on questions like membership and the team's purpose. 43 [E] 题干：Some scholars think teamwork may not always be reliable,despite its potential to work wonders. 44 [I] 题干：To ensure employee's commitment,it is advisable to give them more flexibility as to where and how they work. 45 [C] 题干：Product transitions take much less time now than in the past. 仔细阅读1：46 D Britons have developed the habit of saving. 47 B It will remain gloomy. 48 C Luxurious features add much to the price.49 A They are particular about the quality of toilet paper. 50 D Environmental protection is not much of a concern when Britons buy toilet paper. 仔细阅读2：51 B She succeeded in quitting smoking abruptly. 52 D They were offered nicotine replacements.53 C It is encouraging. 54 B needs some practice first. 55 A They find it even more difficult. 写作：Directions：For this part, you are allowed 30 minutes to write an advertisement on your campus website to sell a computer you used at college.

Here consumers can buy almost everything they need. People don't have to waste a lot of their energy and precious time to go from one shop to another to choose the commodities they like. This is especially desirable to the old, the sick and the busy people who cannot go to the shops in person. All they need to do is to sit in front of their computers and click the mousses. The commodities they order will be delivered to them promptly. 资料来源于网络。
