2017年12月英语六级考试真题答案（第二套）Part I Writing范文"Seek to understand others,and you will be understood"The enlightenment of this saying is not lost in our era but unwilling to understand others seems prevalent. The implication of this message is that people can understand each other as long as they try to do this first;there are,in fact,many who get understood by others because they manage to understand others first.There are several factors to be taken into account when we agree on“seek to understand others,and will be understood”:One reason is that trying to understand others can show your kindness to others.Other people would be thankful,so it is easier for them to accept your ideas.On the other hand,it will let you think what other people think so that you can get to know them better.Therefore,your ideas would have a greater chance to be understood.When we seek to understand others,we elevate the goodwill and team-work spirit.There is a stimulative effect that kicks in when people share this spirit.By seeking to understand others,we boost opportunity for fulfilling understanding between each other.Part II Listening ComprehensionSection ALong Conversation11.【答案】C.They

It’s not that bad, is itM: No, I don’t mind, really. But I can never forget the first speech of thanks I did.W: Why What happenedM: Well, I was in my early twenties. I joined the local history society.W: YesM: Anyway, I went along to a lecture by a Miss Bligh.W: Oh. Do go on.M: She was going to talk with slides about our town in the mid-18th century. She had just published a book on the subject which was reckoned to be quite good. So I went along. When I arrived, the secretary asked me if I could give the speech of thanks. Rather stupidly, I said yes.W: We’ve all done it.M: Anyway, from that point on, I was scared. What should I say I decided to makenotes during the lecture and refer to interesting parts and thank her on behalf of the society. In fact, by the time Miss Bligh stood up to talk, I was feeling much better. But she was so nervous that she kept forgetting what to say, and she spoke almost in a whisper. People at the back kept calling out “We can’t hear.” It was embarrassing.W: I can imagine it.M: At least the slides were good, that is, until the bulb in the projector blew. And she had to finish her talk with no illustrations.W: So what did you say in your speech of thanksM: What can you say You have be polite. I mentioned the interesting facts, referred to the excellent slides, and the finished by saying “We’d all like to thank Miss Bligh for blowing out her slides.”W: Oh, no.M: I felt terrible. I tried to apologize, not very successfully.W: And the speech of thanks this eveningM: I’ll write down exactly what I’m going to say and read it carefully.1.

Well, they are hardly a threat.W: I know they are smaller than us, but we can’t afford to ignore them.M: Yes, you are right, Laurie. But I don’t like extended credit. It ties up cash we could put to better use elsewhere. But, I’ll look into it on Monday.W: Yes. And there is something else.M: Don’t tell me! The letter from the tax revenue officeW: Right. How did you knowM: Tara told me. What’s the problemW: Well.

What is the man think of doingPassage 1A report on sleep and nutrition released this month found that people who consistently went to bed earlier than 11 . took in fewer calories and ate more healthy food. In contrast, “night owls” who go to bed between 11 . and 3 . tend to consume more coffee, alcohol, refined sugars and processed meats than early risers. This report corresponds with the existing scientific literature on bedtime and wellness. The relationship between geeing more sleep and making better food choices is well-documented. A study published last year in The American Journal of Clinical Nutrition found that people who sleep more tend to eat less unhealthy food than their peers who don’t get much rest. And a 2015 study from the University of California, Berkeley, found that teens who go to bed late are more likely to gain weight over a five-year period. As a group, “night owls” types tend to eat less healthy food and take in more calories overall than early risers. The later one goes to bed, the more calories one records the next day. As yet a challenge to explain the cause-and-effect relationship between sleep and nutrition, there may be a third factor that impacts both of them. Or the relationship could be reversed, that is, people who eat less fall asleep earlier.Still, if late sleepers want to lose a few pounds, they can go to bed earlier than they usually do, thereby, reducing their chance of taking snacks before bedtime.do we learn about the report released this month10. What does the study from the University of California, Berkeley, find about teens who go to bed late11. Wha t should “night owls” do to reduce their consumption of unhealthy food Passage 2Researchers have found not just a diversity problem in Hollywood but actually an inclusion crisis. With less than a week before an Oscars ceremony that has already been criticized for an all-whit list of acting nominees, a study shows the film industry does worse than television. Just percent of film directors were female, and only 7 percent of films has cast whose balance of race and ethnicity reflected the country’s div ersity. When researches looked at all TV shows, they also found that women of color over 40 were regarded as “largely invisible” and just 22 percent of TV series creators were female. Overall, the study found half the films and TV shows had no Asian speaking characters and more than one-fifth of them had no black characters with dialogue. The film industry still functions as a straight, whit, boy’s club. When looking at how women are depicted, the study found female characters were four times more likely to be shown in sexy clothing and nearly four times as likely to be referred to as physically attractive. But their results also indicated films and TV shows withwomen or people of color in the important jobs behind the scenes—director, producer or writer—tended to have better diversity numbers. Across TV and film, the underrepresentation of non-white characters falls mostly on Hispanics. Among more than 10,000 characters, proportions of white, black and Asian characters came close to . population figures. But Hispanics were just percent of characters, despite being about 17 percent of the . population.12. Why has the Oscars ceremony been criticized13. What do we learn from the research14. Who are regarded as “largely invisible” on TV shows15. What does the speaker say about HispanicLecture 1When purchasing life insurance, there are many important factors to consider. One should buy the policies that give the most protection at the least cost, ensure the right family members, and consider the family’s financial needs. It is important to buy the insurance from companies that are financially sound and that are represented by honest, well-trained agents. At various stages in a person’s life, different kinds of life insurance are needed for particular situations. Jerry is single and has no dependents. Probable the only life insurance he needs is enough to cover his debts and burial expenses. Insurance can be purchased at a lower rate during the young years, but by buying while young, the premiums are paid in for a longer period of time. In the end, the amount paid for premium isabout the same. A person shouldn’t buy insurance protection that really isn’t necessary. Suppose that Jerry marries Jeannette, who is a college graduate and is working. Perhaps enough insurance would be needed to cover their debts and burial expenses. Now, Jeanette has quit work and their first child is on the way. They have purchased a home with a small down payment and a 30-year mortgage. The situation regarding life insurance takes on a different look. There are dependents who need financial protection. How much insurance is needed As the family increase in size, it is essential to add more insurance on the breadwinner to protect the dependents. When the children are young and depend upon the family for financial need, families with modest incomes have difficulty providing enough life insurance to protect the mother and the children. Families with modest incomes should insure the breadwinner or breadwinners first. When considering the amount of insurance for the mother with dependent children, substitute child care is a need that should be planned for until the children can care for themselves. The death of a small child would have no effect upon the income of the family. Perhaps a policy to meet funeral expenses would sufficient for the young child, although most people do not take out insurance on their young children. As the children become financially independent of the family, the emphasis on family financial security will shift from protection to saving for the retirement years. Every family situation is different, but it is important that each family give adequate thought to planning its financial future.16. What life insurance should a singe person buy, according to the speaker17. What should people do as their family increases in size18. When should one change their life insuranceLecture 2“Stereotype” may sound like a bad word, but there’s nothing bad about it. For one thing, stereotypes are often accurate. When you ask people about their concept of stereotypes, they get it pretty much right. Also, stereotypes are often positive, particularly of groups that we ourselves belong to. Some of the statistical generalizations may be positive as some groups have reputations for being smart, for being loyal, for being brave, for all sorts of things that are not at all negative. And so there’s nothing inherently wrong abut stereotypes.But there are problems with stereotypes. For one thing, they’re reliable insofar as they’re based on unbiased samples. But a lot of the information we get about human groups is through biased sources like how they’re represented in the media. And if these sources don’t give you an accurate depiction, your stereotype won’t be accurate.For e xample, many Jews have been troubled by Shakespeare’s depiction of Shylock. If the only Jew you know is Shakespeare’s Shylock, it’s going to be a very bad impression. So one problem with stereotypes is while we are good at drawing conclusions from them, of ten our information isn’t reliable.A second problem is that stereotypes, regardless of whether or not they’re accurate, can have a negative effect on the people that they apply to. And this is what psychologist, Claude Steele, described as stereotype threat. He has a vivid example of this. Here’s how to make African-Americans do worse on a math test. You have the test and you put on the test that they have to identify theirrace. The very act of acknowledging that they are African-Americans when given a test ignites in them thoughts of their own stereotype which is negative regarding academics and that makes them do worse. Want to know how to make a woman do worse on a math test Same thing, get her to write down her sex.One recent study found a sort of clever twist on this. When Asian-American women are given a test and they’re asked to mark down their race, they do better than they would otherwise do. They’re reminded of a positive stereotype that boosts their morale. You ask them, on the other hand, to mark down their sex, they do worse because they are reminded of a negative stereotype. That’s an example of how stereotypes have a potentially damaging effect on people.19. What does the speaker say about stereotype20. What lead to the bias of stereotype21. What does the speaker say is a problem with stereotypes22. What did one recent study find about stereotypeLecture 3Sometimes when you take a common drug, you may have a side effect. That is, the drug may cause some effect other than its intended one. When these side effects occur, they are called adverse reactions. Whenever you have an adverse reaction, you should stop taking the drug right away. Ask your pharmacist whether he can suggest a drug that will relieve the symptoms but that will not cause the adverse reaction. If an adverse reaction to a drug is serious, consult your doctor for advice at once.Drugs that are safe in the dosage stated on the label may be very dangerous in large dose. For example, aspirin is seldom thought of as dangerous, but there are many reports of accidental poisoning of young children who take too many aspirin pills as well as the possible development of Reye syndrome in children with flu. In adults, excessive used of some pain-killing drugs may cause serve kidney damage. Some drugs for relief of stomach upsets, when taken in excess, can perhaps cause serious digestive problems. You should never use any over-the-counter drug on a regular, continued basis, or in large quantities, except on your doctor’s advice. Y ou could be suffering from a serious illness that needs a doctor’s care.Each drug you take not only acts on the body but may also alter the effect of any other drug you are taking. Sometimes, this can cause dangerous or even fatal reactions. For example, aspirin increases the blood-thinning effects of drugs given to patients with heart disease. Therefore, a patient who has been taking such a drug may risk bleeding if her or she uses aspirin for a headache. Before using several drugs together you should ask your doctor and follow his advice. Your pharmacist can tell you whether certain drugs can safely be taken together.Alcohol may increase the effect of a drug—sleeping pills combine with alcohol to produce a sleepy feeling. When taking any drug, you should ask your doctor whether drinking alcohol could be dangerous in combination with the medicine. Experts believe there is a relationship between adult abuse of legitimate medicines and the drug culture has swept our country. You can do your shar to reduce the chances that your children will become part of the drug culture bytreating all medicines with respect. Always let your children know that medicines and drugs should not be used carelessly.23. What does the speaker say you should do when you have an adverse reaction24. What does the speaker say about alcohol drinking25. What does the speaker call on parents to do at the end of the talk。

2016年12月大学英语六级考试真题听力原文及参考答案(第2套)

2016年12月大学英语六级考试真题（第2套）参考答案Part IV TranslationThe number of Chinese language learners undergoes a dramatic rise as China’s economy surges, which has turned Chinese into one of the most popular language among language learners across the world. In recent years, Chinese universities are moving up significantly in the world university rankings. Owing to the great advances in its educational system, China now ranks unsurprisingly as one of the most favored destinations for overseas students. In 2015, there were around 400,000 overseas students flocking to China to pursue their studies. They no longer restrict their interest to Chinese language and culture, instead, branching out into other subjects including science and engineering. Although the United States and the United Kingdom are still dominant in the global education market, China is catching up at a fast pace with them.Part II Listening Comprehension听力原文Section AQuestions 1 to 4 are based on the conversation you have just heard.M: Guess what? The worst food I ever had was in France.W: Really? That's odd. I thought the French were all good cooks.M: Yes, that's right. I suppose it's really like anywhere else, though. You know, some places are good, some bad. But it's really all our own fault.W: What do you mean?M: Well, it was the first time I'd been to France. This was years ago when I was at school. I went there with my parents' friends, from my father's school. They’d hired a coach to take them to Switzerland.W: A school trip?M: Right. Most of them had never been abroad before. We'd crossed the English Channel at night and we set off through France and breakfast time arrived, and the coach driver had arranged for us to stop at this little café. There we all were tired and hungry and then we made a great discovery. W: What was that?M: Bacon and eggs.W: Fantastic! The real English breakfast.M: Yes, anyway we didn't know any better--- so we had it, and ugh...!W: What was it like? Disgusting?M: Ah, it was incredible. They just got a bowl and put some fat in it. And then they put some bacon in the fat, broke an egg over the top and put the whole lot in the oven for about ten minutes. W: In the oven? You're joking. You can't cook bacon and eggs in the oven!M: Well, they must have done it that way. It was hot, but it wasn't cooked. There was just this egg floating about in gallons of fat and raw bacon.W: Did you actually eat it?M: No, nobody did. They all wanted to turn round and go home. You know, back to teabags and fish and chips. You can't blame them really. Anyway, the next night we were all given another foreign specialty.W: What was that?M: Snails--that really finished them off. Lovely holiday that was!1. What did the woman think of the French?2. Who did the man travel with on his first trip to Switzerland?3. What does the man say about the breakfast at the little French café?4. What did the man think of his holiday in France?Questions 5 to 8 are based on the conversation you have just heard.M: You say your shop has been doing well. Could you give me some idea of what “doing well” means in facts and figures?W: Well, “doing well” means averaging 1,200 pounds or more a week for about 7 years, making almost a quarter of a million pounds. And “doing well” means your earnings are rising. Last year we did slightly over 50,000 and this year we hope to do more than 60,000. So that's good if we continue to rise.M: Now that's growth on earnings, I assume. What about your expenses?W: Yes, that's growth. The expenses of course go up steadily. And since we've moved to this new shop, the expenses have increased greatly because it's a much bigger shop. So I couldn't say exactly what our expenses are. There's something in the region of 6 or 7 thousand pounds a year, which is not high---commercially speaking, it's very low. And we try to keep our expenses as low as we can.M: And your prices are much lower than the same goods in shops round about. How do the local shopkeepers feel about having a shop doing so well in their midst?W: Perhaps a lot of them don't realize how well we're doing because we don't make a point of publicizing. That was a lesson we learned very early on. We were very friendly with all local shopkeepers and we have been to mention to a local shopkeeper how much we have made that week. He was very unhappy and never as friendly again. So we make a point of never publicizing the amount of the money we make. But we're on very good terms with all the shops; none of them have ever complained that we're putting them out of business or anything like that. I think it's a nice funny relationship. Maybe if they did know what we made, perhaps they wouldn't be so friendly.5. What are the speakers mainly talking about?6. What does the woman say her shop tries to do?7. What do we learn about goods sold at the woman's shop?8. Why doesn't the woman want to make known their earnings anymore?Section BQuestions 9 to 12 are based on the passage you have just heard.Birds are famous for carrying things around. Some, like homing pigeons, can be trained to deliver messages and packages. Other birds unknowingly carry seeds that cling to them for the ride. Canadian scientists have found a worrisome, new example of the power that birds have to spread stuff around. Way up north in the Canadian Arctic, seabirds are picking up dangerous chemicals in the ocean and delivering them to ponds near where the birds live.Some 10,000 pairs of the birds, called fulmars, a kind of Arctic seabird, make their nests on Devon Island, north of the Arctic Circle. The fulmars travel some 400 kilometers over the sea to find food. When they return home, their droppings end up all around their nesting sites, including in nearby ponds.Previously, scientists noticed pollutants arriving in the Arctic with the wind. Salmon also carry dangerous chemicals, as the fish migrate between rivers and the sea. The bodies of fish and other meat-eaters can build up high levels of the chemicals.To test the polluting power of fulmars, researchers collected samples of deposits from 11 ponds on Devon Island. In ponds closest to the colony, the results showed that there were far more pollutants than in ponds less affected by the birds. The pollutants in the ponds appear to come from fish that fulmars eat when they're out on the ocean. People who live, hunt, or fish near bird colonies need to be careful, the researchers say. The birds don't mean to cause harm, but the chemicals they carry can cause major problems.9. What have Canadian scientists found about some seabirds?10. What does the speaker say about the seabirds called fulmars?11. What did scientists previously notice about pollutants in the Arctic?12. What does the speaker warn about at the end of the talk?Questions 13 to 15 are based on the passage you have just heard.In recent years, the death rate among American centenarians -- people who have lived to age 100 or older--has decreased, dropping 14 percent for women and 20 percent for men from 2008 to 2014. The leading causes of death in this age group are also changing. In 2000, the top five causes of death for centenarians were heart disease, stroke, flu, cancer and Alzheimer's disease. But by 2014, the death rate from Alzheimer's disease for this age group had more than doubled--increasing from 3.8 percent to 8.5 percent --making the progressive brain disease the second leading cause of death for centenarians. One reason for the rise in deaths from Alzheimer's disease in this group may be that developing this condition remains possible even after people beat the odds of dying from other diseases such as cancer.People physically fit enough to survive over 100 years ultimately give in to diseases such as Alzheimer's which effects the mind and cognitive function. In other words, it appears their minds give out before their bodies do. On the other hand, the death rate from flu dropped from 7.4 percent in 2000 to 4.1 percent in 2014. That pushed flu from the third leading cause of death to the fifth.Overall, the total number of centenarians is going up. In 2014, there were 72,197 centenarians, compared to 50,281 in 2000. But because this population is getting larger, the number of deaths in this group is also increasing --18,434 centenarians died in 2000, whereas 25,914 died in 2014.13. What does the speaker say about the risk of dying for American centenarians in recent years?14. What does the speaker say about Alzheimer's disease?15. What is characteristic of people who live up to 100 years and beyond?Section CQuestions 16 to 18 are based on the recording you have just heard.Okay. So let's get started. And to start things off I think what we need to do is consider a definition. I'm going to define what love is but then most of the experiments I'm going to talk about are really focused more on attraction than love. And I'm going to pick a definition from a former colleague, Robert Sternberg, who is now the dean at Tufts University but was here on our faculty at Yale for nearly thirty years. And he has a theory of love that argues that it's made up of three components: intimacy, passion, and commitment, or what is sometimes called decision commitment. And these are relatively straightforward. He argued that you don't have love if you don't have all three of these elements.Intimacy is the feeling of closeness, of connectedness with someone, of bonding. Operationally, you could think of intimacy as you share secrets, you share information with this person that you don't share with anybody else. Okay. That's really what intimacy is, the bond that comes from sharing information that isn't shared with other people. The second element is passion. Passion is the drive that leads to romance. You can think of it as physical attraction. And Sternberg argues that this is a required component of a love relationship. The third element of love in Sternberg's theory is what he calls decision commitment, the decision that one is in a love relationship, the willingness to label it as such, and a commitment to maintain that relationship at least for some period of time. Sternberg would argue it's not love if you don't call it love and if you don't have some desire to maintain the relationship. So if you have all three of these, intimacy, passion and commitment, in Sternberg's theory you have love. Now what's interesting about the theory is what do you have if you only have one out of three or two out of three? What do you have and how is it different if you have a different two out of three? What's interesting about this kind of theorizing is it gives rise to many different combinations that can be quite interesting when you break them down and start to look at them carefully. So what I've done is I've taken Sternberg's three elements of love, intimacy, passion and commitment, and I've listed out the different kinds of relationships you would have if you had zero, one, two or three out of the three elements.16. What does the speaker say about most of the experiments mentioned in his talk?17. What does Robert Sternberg argue about love?18. What question does the speaker think is interesting about Sternberg's three elements of love?Questions 19 to 22 are based on the recording you have just heard.Hi, I'm Elizabeth Hoffler, Master of Social Work. I'm a social worker, a lobbyist and a special assistant to the Executive Director at the National Association of Social Workers. Today we are going to be talking about becoming a social worker. Social work is the helping profession. Its primary mission is to enhance human well-being and help meet the basic needs of all people, with a particular focus on those who are vulnerable, oppressed, and living in poverty. We often deal with complex human needs. Social work is different from other professions, because we focus on the person and environment. We deal with the external factors that impact a person's situation and outlook. And we create opportunity for assessment and intervention to help clients and communities cope effectively with their reality and change that reality when necessary.In thousands of ways social workers help other people --people from every age, every background, across the country. Wherever needed, social workers come to help. The most well-known aspect of the profession is that of a social safety net. We help guide people to critical resources and counsel them on life-changing decisions. There are more than six hundred thousand professional social workers in the country, and we all either have a bachelor's degree, a master's degree, or a PhD in social work. There are more clinically-trained social workers than clinically-trained psychiatrists, psychologists and psychiatric nurses combined.Throughout this series, you will learn more about the profession, the necessary steps to get a social work degree, the rich history of social work and many ways that social workers help others.Later in this series, you'll hear from Stacy Collins and Mel Wilson, fellow social workers at the National Association of Social Workers. Stacy is going to walk you through the step-by-step process of becoming a social worker, and Mel will tell you about the range of options you have once you get your social work degree, as well as the high standards of responsibility that social workers must adhere to.The National Association of Social Workers represents nearly 145,000 social workers across the country. Our mission is to promote, protect and advance the social work profession. We hope you enjoy this series about how you can make a difference by becoming a social worker. Next, we are going to talk about choosing social work.19. What does the speaker mainly talk about?20. What do social workers mainly do?21. What do professional social workers have in common according to the speaker?22. What is Mell Wilson going to talk about in the series?Questions 23 to 25 are based on the recording you have just heard.Today, I'd like to talk about what happens when celebrity role models get behind healthy habits but at the same time promote junk food? Currently, there is mounting criticism of Michelle Obama's “Let's Move!” campaign, which fights childhood obesity by encouraging youngsters to become more physically active, and has signed on singer Beyoncé, and basketball player Shaquille O'Neal, both of whom also endorse sodas, which are a major contributor to the obesity epidemic. Now there's a lot more evidence of how powerful a celebrity -- especially a professional athlete --can be in influencing children's behavior.In a report published by the Rudd Center for Food Policy and Obesity at Yale University, researchers studied 100 professional athletes and their endorsement contracts. The team focused on athletes since they are theoretically the best role models for active, healthy lifestyles for children. After sorting the deals by category, they determined that among the 512 brands associated with the athletes, most involved sporting goods, followed closely by food and beverage brands.Sports drinks, which are often high in sugar and calories, made up most of the food and drink deals, with soft drinks and fast food filling out the remainder. Of the 46 beverages endorsed by professional athletes, 93% relied exclusively on sugar for all of their calories.It's no surprise that high profile athletes can influence children's eating behaviors, but the scientists were able to quantify how prevalent these endorsements are in the children's environment. Advertisements featuring professional athletes and their endorsed products tend to get impressive exposure, on TV, radio, in print and online. And in 2010, the researchers reported that children ages 12 to 17 saw more athlete-endorsed food and beverage brand commercials than adults.One reason any campaign wants a popular celebrity spokesperson is because kids are attracted to them no matter what they are doing. We can't expect kids to turn off that admiration when the same person is selling sugar. At best, kids might be confused. At worst, they'll think themessages about soda are the same as the messages about water. But those two beverages aren't the same.If children are turning to athletes as role models, it's in their best interest if their idols are consistent. Consistent messaging of positive behaviors will show healthier lifestyles for kids to follow.23. What is the aim of Michelle Obama's campaign?24. What does research find about advertisements featuring professional athletes?25. What does the speaker think kids' idols should do?This is the end of Listening Comprehension.。

What is the man think of doing?Passage 1A report on sleep and nutrition released this month found that people who consistently went to bed earlier than 11 p.m.took in fewer calories and ate more healthy food. In contrast, “night owls” who go to bed between 11 p.m to consume more coffee, alcohol, refined sugars and processed meats than early risers. This report corresponds with theexisting scientific literature on bedtime and wellness. The relationship between geeing more sleep and making better foodchoices is well-documented. A study published last year in The American Journal of Clinical Nutrition found that peoplewho sleep more tend to eat less unhealthy food than their peers who don’t get much rest. And a 2015 study from the University of California, Berkeley, found that teens who go to bed late are more likely to gain weight over a five-year period.neAs a group, “night owls” types tend to eat less healthy food and take in more calories overall than early risers. The later o goes to bed, the more calories one records the next day. As yet a challenge to explain the cause-and-effect relationship between sleep and nutrition, there may be a third factor that impacts both of them. Or the relationship could be reversed,that is, people who eat less fall asleep earlier. Still, if late sleepers want to lose a few pounds, they can go to bed earlier thanthey usually do, thereby, reducing their chance of taking snacks before bedtime.9.What do we learn about the report released this month?10. What does the study from the University of California, Berkeley, find about teens who go to bed late?11. What should “night owls” do to reduce their consumption of unhealthy food?Passage 2Researchers have found not just a diversity problem in Hollywood but actually an inclusion crisis. With less than aweek before an Oscars ceremony that has already been criticized for an all-whit list of acting nominees, a study shows thefilm industry does worse than television. Just 3.4 percent of film directors were female, and only 7 percent of films has castwhose balance of race and ethnicity reflected the country’s diversity. When researches looked at all TV shows, they a found that women of color over 40 were regarded as “largely invisible”　and just 22 percent of TV series creators were female. Overall, the study found half the films and TV shows had no Asian speaking characters and more than one-fifth ofthem had no black characters with dialogue. The film industry still functions as a straight, whit, boy thow women are depicted, the study found female characters were four times more likely to be shown in sexy clothing andnearly four times as likely to be referred to as physically attractive. But their results also indicated films and TV shows withwomen or people of color in the important jobs behind the scenes—director, producer or writer—tended to have better diversity numbers. Across TV and film, the underrepresentation of non-white characters falls mostly on Hispanics. Amongmore than 10,000 characters, proportions of white, black and Asian characters came close to U.S. population figures. ButHispanics were just 5.8 percent of characters, despite being about 17 percent of the U.S. population.12. Why has the Oscars ceremony been criticized?13. What do we learn from the research?14. Who are regarded as “largely invisible” on TV shows?15. What does the speaker say about Hispanic?Lecture 1When purchasing life insurance, there are many important factors to consider. One should buy the policies that give themost protection at the least cost, e nsure the right family members, and consider the family’s financial needs. It is to buy the insurance from companies that are financially sound and that are represented by honest, well-trained agents. Atnt kinds of life insurance are needed for particular situations. Jerry is single and hasvarious stages in a person’s life, differeno dependents. Probable the only life insurance he needs is enough to cover his debts and burial expenses. Insurance can be purchased at a lower rate during the young years, but by buying while young, the premiums are paid in for a longer periodof time. In the end, the amount paid for premium is about the same. A person shouldn’t buy insurance pr, who is a college graduate and is working. Perhaps enough insuranceisn’t necessary. Suppose that Jerry marries Jeannettewould be needed to cover their debts and burial expenses. Now, Jeanette has quit work and their first child is on the way.They have purchased a home with a small down payment and a 30-year mortgage. The situation regarding life insurancetakes on a different look. There are dependents who need financial protection. How much insurance is needed? As thefamily increase in size, it is essential to add more insurance on the breadwinner to protect the dependents. When the children are young and depend upon the family for financial need, families with modest incomes have difficulty providingenough life insurance to protect the mother and the children. Families with modest incomes should insure the breadwinneror breadwinners first. When considering the amount of insurance for the mother with dependent children, substitute childcare is a need that should be planned for until the children can care for themselves. The death of a small child would haveno effect upon the income of the family. Perhaps a policy to meet funeral expenses would sufficient for the young child,although most people do not take out insurance on their young children. As the children become financially independent ofthe family, the emphasis on family financial security will shift from protection to saving for the retirement years. Everyfamily situation is different, but it is important that each family give adequate thought to planning its financial future.16. What life insurance should a singe person buy, according to the speaker?17. What should people do as their family increases in size?18. When should one change their life insurance?Lecture 2“Stereotype” may sound like a bad word, but there’s nothing bad about it.For one thing, stereotypes are often accurate.When you ask people about their concept of stereotypes, they get it pretty much right. Also, stereotypes are often positive,particularly of groups that we ourselves belong to. Some of the statistical generalizations may be positive as some groupshave reputations for being smart, for being loyal, for being brave, for all sorts of things that are not at all negative. And sothere’s nothing inherently wrong abut stereotypes.But there are problems with stereoty pes. For one thing, they’re reliable insofar as they’re based on unbia But a lot of the information we get about human groups is through biased sources like how they’re re And if these sources don’t give you an accurate depiction, your stereotype won’t be accurate.For example, many Jews have been troubled by Shakespeare’sdepiction of Shylock. If the only Jew you know ise we are good at Shakespeare’s Shylock, it’s going to be a very bad impression. So one problem with stereotypes is whildrawing conclusions from them, often our information isn’t reliable.A second problem is that stereotypes, regardless of whether or not they’re accurate, can have a negati people that they apply to. And this is what psychologist, Claude Steele, described as stereotype threat. He has a vivid-Americans do worse on a math test. You have the test and you put on the testexample of this. Here’s how to make Africanthat they have to identify their race. The very act of acknowledging that they are African-Americans when given a testignites in them thoughts of their own stereotype which is negative regarding academics and that makes them do worse. Wantto know how to make a woman do worse on a math test? Same thing, get her to write down her sex.One recent study found a sort of clever twist on this. When Asian-American women are given a test and they’re as to mark down their race, they do better than they would otherwise do. They’re reminded of a positive stereo their morale. You ask them, on the other hand, to mark down their sex, they do worse because they are reminded of a negative stereotype. That’s an example of how stereotypes have a potentially damaging effect on people.19. What does the speaker say about stereotype?20. What lead to the bias of stereotype?21. What does the speaker say is a problem with stereotypes?22. What did one recent study find about stereotype?Lecture 3Sometimes when you take a common drug, you may have a side effect. That is, the drug may cause some effect otherthan its intended one. When these side effects occur, they are called adverse reactions. Whenever you have an adverse reaction, you should stop taking the drug right away. Ask your pharmacist whether he can suggest a drug that will relievethe symptoms but that will not cause the adverse reaction. If an adverse reaction to a drug is serious, consult your doctor for advice at once.Drugs that are safe in the dosage stated on the label may be very dangerous in large dose. For example, aspirin is seldom thought of as dangerous, but there are many reports of accidental poisoning of young children who take too manyaspirin pills as well as the possible development of Reye syndrome in children with flu. In adults, excessive used of somepain-killing drugs may cause serve kidney damage. Some drugs for relief of stomach upsets, when taken in excess, can perhaps cause serious digestive problems. You should never use any over-the-counter drug on a regular, continued basis, orin large q uantities, except on your doctor’s advice. You could be suffering from a serious illness that needs a doctor Each drug you take not only acts on the body but may also alter the effect of any other drug you are taking. Sometimes,this can cause dangerous or even fatal reactions. For example, aspirin increases the blood-thinning effects of drugs given to patients with heart disease. Therefore, a patient who has been taking such a drug may risk bleeding if her or she uses aspirinfor a headache. Before using several drugs together you should ask your doctor and follow his advice. Your pharmacist cantell you whether certain drugs can safely be taken together.Alcohol may increase the effect of a drug—sleeping pills combine with alcohol to produce a sleepy feeling. When taking any drug, you should ask your doctor whether drinking alcohol could be dangerous in combination with the medicine.Experts believe there is a relationship between adult abuse of legitimate medicines and the drug culture has swept our country. You can do your shar to reduce the chances that your children will become part of the drug culture by treating all medicines with respect. Always let your children know that medicines and drugs should not be used carelessly.23. What does the speaker say you should do when you have an adverse reaction?24. What does the speaker say about alcohol drinking?25. What does the speaker call on parents to do at the end of the talk?。

2017年12月六级仔细阅读真题及解析(卷二)

Passage OneQuestions 46 to 50 are based on the following passage.You may have heard that Coca-Cola once contained an ingredient capable of sparking particular devotion in consumers: cocaine. The“coca” in the name referred to the extracts of coca leaf that the drinks originator, chemist John Pemberton, mixed with his sugary syrup(姜汁). At the time, coca leaf extract mixed with wine was a common tonic(滋补品), and Pemberton’s sweet brew was a way to get around local laws prohibiting the sale of alcohol. But the other half of the name represents another ingredient，less infamous(名声不好的), perhaps, but also strangely potent: the kola nut.In West Africa, people have long chewed kola nuts as stimulants, because they contain caffeine that also occurs naturally in tea, coffee, and chocolate. They also have heart stimulants.Historian Paul Lovejoy relates that the cultivation of kola nuts in West Africa is hundreds of years old. The leafy, spreading trees were planted on graves and as part of traditional rituals. Even though the nuts, which need to stay moist, can be somewhat delicate to transport, traders carried them hundreds of miles throughout the forests and grasslands.Europeans did not know of them until the 1500s, when Portuguese ships arrived on the coast of what is now Sierra Leone. And while the Portuguese took part in the trade, ferrying nuts down the coast along with other goods, by 1620, when English explorer Richard Jobson made his way up the Gambia, the nuts were still peculiar to his eyes.By the late 19th century, kola nuts were being shipped by the tonne to Europe and the US. Many made their way into medicines, intended as a kind of energy boost. One such popular medicinal drink was Vin Mariani, a French product consisting of coca extract mixed with red wine. It was created by a French chemist, Angelo Mariani, in 1863. So when Pemberton created his drink,it represented an ongoing trend. When cocaine eventually fell from grace as a beverage ingredient, kola-extract colas became popular.The first year it was available, Coca-Cola averaged nine servings a day across all the Atlanta soda fountains where it was sold. As it grew more popular, the company sold rights to bottle the soda, so it could travel easily. Today about 1.9 billion Cokes are purchased daily. It’s become so iconic that attempts to change its taste in 1985 —sweetening it in a move projected to boost sales —proved disastrous, withwidespread anger from consumers. “Coca-Cola Classic”，returned to store shelves just three months after the “New Coke” was released.These days, the Coca-Cola recipe is a closely guarded secret. But it’s said to no longer contain kola nut extract, relying instead on artificial imitations to achieve the flavour.你可能听说可口可乐曾经含有一种能够使消费者“死忠”的成分：可卡因。

Everybody has a scary story about someone getting scooped(被抢先),” says new York university astronomer david hogg. those fears may be a factor in a lingering hesitation to share data even when publishing in journals that mandate it.[H] researchers at small labs or at institutions focused on teaching arguably have the most to lose when sharing hard-won data. ""with my institution and teaching load, i don't have postdocs and grad students", says terry mcglynn, a tropical biologist at california state university,Dominguez hills. "the stakes are higher to share data because it's a bigger fraction of hats happening in my lab.[I] researchers also point to the time sink that is involved in preparing data for others toview.Once the data and associated materials appear in a repository(存储库), answering questions and handling complaints can take many hours.[J] the time investment can present other problems. in some cases, says data scientist karthik Ram, it may be difficult for junior researchers to embrace openness when senior colleagues manyof whom head selection and promotion teesht ridicule what they may view as misplaced energies. "i've heard this recently -that embracing the idea of open datad code makes traditional academics uncomfortable, "says ram. "the concem seems to be that open advocates don't spend their time being as productive as possible."[ K]an open-science stance can also add complexity to a collaboration. kate ratliff, who studies social attitudes at the university of florida, gainesville, says that it can seem as if there are two camps in a field-those who care about open science and those who don't . " there a new area to navigate-'are you cool with the fact that i'll want to make the data open?'-when talking with somebody about an interesting research idea, "she says.[L] despite complications and concerns, the upsides of sharing can be significant. for example,when information is uploaded to a repository, a digital object identifier(DOI)is assigned.Scientists can use a DOT to publish each step of the research life cycle, not just the final paper. In so doing, they can potentially get three citations- one each for the data and software.in addition to the paper itself. and although some say that citations for software or data have little currency in academia,they can have other benefits.[M] many advocates think that transparent data procedures with a date and time stamp will protect scientists from being scooped. "this is the sweet spot between sharing and getting credit for it. while discouraging plagiarism(剽窃). " says ivo grigorov, a project coordinator at the naional institute of aquatic resotResearch secreta - in charlottenlund, denmark. hogg says that scooping is less of a problem than many think. "the two cases i'm familiar with didn't involve open data or code, "he says.[N] Open science also offers junior researchers the chance to level the palying field by gaining better access to crucial date. ross mounce, a postdoc studying evolutionary biology at the university of cambrige,UK, is a vocal champion of open science, partly because his fossil others' data. he says that more openness in science could help to discourage what some perceive as a commom practice of shutting out early-career scientists' requests for data.[O] communication also helps for those who worry about jeopardizing a collaboration, hesays,Concems about open should be discussed at the outset of a study. "whenever you start a project with someone, you have to establish a clear understanding of expectations for who owns the data, at what point they go public and who can do what with them, he says.[p] in the end, sharing data, software and materials with colleagues can help an early -career researcher to gain recognition--a crucial component of success. "the thing you are searching for reputation" says titus brown,a genomics(基因组学) researcher at the university of Califomia, davis,."to get grants and jobs you have to be relevant and achieve some level of public recognition. anything you do that advances your presence- especially in a largerphere, outside the communities you know- is a net win."36. astronomer david hogg doesn't think scooping is as serious a problem as generally thought.37. some researchers are hesitant to make their data public for fear that others might publish something similar before them38. some psychology joumals have offered incentives to encourage authors to share their data.39. there is a growing demand in the science community that research data be open to the public.40. sharing data offers early-career researchers the chance to build a certain level of reputation41. data sharing enables scientists to publish each step of their research work, thus leading to more citations42. scientists hold different opinions about the extent and timing of data sharing43. potential problems related to data sharing should be made known to and discussed by all participants at the beginning of a joint research project44. sharing data and handling data-related issues can be time-consuming45. junior researehers may have no say when it comes to sharing data.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.In the beginning of the movie, robot, a robot has to decide whom to save after two cars plunge into the water-del spooner or a child. even though spooner screams"save her save her! "the robot rescues him because it calculates that he has a 45 percent chance of survival compared to sarah's 11 percent. the robot's decision and its calculated approach raise an important question:would humans make the same choice? and which choice would we want our robotic counterparts to make?Isaac asimov evaded the whole notion of morality in devising his three laws of robotics, which hold that 1. robots cannot harm humans or allow humans to come to harm; 2. robots must obey humans, except where the order would conflict with law i; and 3. robots must act inself-preservation, unless doing so conflicts with laws i or 2. these laws are programmed intoasimov's robots-they don' t have to think, judge, or value. they don't have to like humans or believe that wrong or bad. they simply don't do it.The robot who rescues spooner s life in / robot follows asimov's zeroth law: robots cannot harm humanity(as opposed to individual humansor allow humanity to come to harm--an expansion of the first law that allows robots to determine what's in the greater good. under the first law,a robot could not harm a dangerous gunman, but under the zeroth law, a robot could kill the gunman to save others.Whether it's possible to program a robot with safeguards such as asimov's laws is debatable a word such as"harm"is vague (what about emotional harm is replacing a human employ harm), and abstract concepts present coding problems. the robots in asimov's fiction expose complications and loopholes in the three laws, and even when the laws work, robots still have to assess situation.Assessing situations can be complicated. a robot has to identify the players, conditions, and possibe outcomes for various scenarios,Its doubtful that a computer program can do that-aleast, not without some undesirable results. a roboticist at the bristol robotics laboratory programmed a robot to save huroxies(5) called""from danger. when one h-boheaded for danger, the robot successfully pushed it out of the way. but when two h-bots became percent of the time, unable to decide which to save and letting them both"die. "the experiment highlights the importance of morality without it, how can a robotdecide whom to save or what's best for humanity, especially if it can't calculate survival odds?46. what question does the example in the movie raise?a) whether robots can reach better decisionsb) whether robots follow asimov's zero"d) how robots should be programmed.47. what does the author think of asimovs three laws of robotics?a) they are apparently divorced from reality.b)they did not follow the coding system of robotics.c)they laid a solid foundation for robotics.d) they did not take moral issues into consideration.48. what does the author say about asimov's robots?a they know what is good or bad for human beingsb)they are programmed not to hurt human begingsc)they perform duties in their owners'best interest.d)they stop working when a moral issue is involved.49. what does the author want to say by mentioning the word"harm"in asimov's laws?a)abstract concepts are hard to program.b) it is hard for robots to make decisionsc) robots may do harm in certain situationsd) asimov's laws use too many vague terms50. what has the roboticist at the bristol robotics laboratory found in his experiment.a）robots can be made as intelligent as human begings some dayb) robots can have moral issues encoded into their programc)robots can have trouble making decisions in complex scenarion.d)robots can be programmed to perceive potential perils.PassageTwoQuestions 5i to 55 are based on the following passage.Our world now moves so fast that we seldom stop to see just how fast we seldom stop to see just how far wu have come in just a few year.The latest iPone 6s,for example,has a dual-core proccssor and fite nicely into your pocket. by comparison, you would expect to find a technological specification like this on your tandard laptop in an office anywhere in the world.its no wonder shat new applications for the internet of things are moving ahcad fast when almost every new decice we buy has a plup on the eng of it or a wireless connection to the internet. Soon, our current smartphone lifestyle wilate our own smart home lifestyle too.All researches agree that close to 25 billion devices,things and sensors will be connected by 2020 which incidentally is also the moment that millennials(千禧一代) are expected to make up of ouroverall workforce, and the fully connected home . become a reality for large umbers of people worldwide.However this is just the tip of the proverbial iceberg as smart buildings and even cities increasingly become the norm as leaders and business owners begin to wake up to the massive savings that technology can deliver through connected sensors and new forms of automation coupled with ligent energy and facilities managemen.Online security cameras, intelligent lighting and a wealth of sensors that control both temperature and air quality are offering an unprecedented level of control, efficiency, and improvements to hat were once classed necessary costs when running a business or managing a large building.We can expect that the ever-growing list of devices, systems and environments remain connected,always online and talking to each other. the big benefit will not only be in the housing of this enormous and rapidly growing amount of data, but will also be in the ability to run real time data analytics to extract actionable and ongoing knowledge.The biggest and most exciting challenge of this technology is how to creatively leverage this ever-growing amount of data to deliver cost savings, improvements and tangible benefits to both businesses and citizens of these smart citiesThe good news is that most of this technology is already invented. let's face it, it wasn't too long ago that the idea of working from anywhere and at anytime was some form of a distant utopim(乌托邦式的) dream, and yet now we can perform almost any office-based task from any location in the world as long as we have access to the internet.it's time to wake up to the fact that making smart buildings, cities and homes will dramatically improve our quality of life in the years ahead.51.What does the example of iphone 6s serve to show?a)the huge capacity of the smartphones people now useb)the widespread use of smartphones all over the worldc)the huge impact of new technology on people's everyday life.d)the rapid technological progress in a very short period of time52. what can we expect to see by the year 2020?a)apps for the internet of thingsc)the emergence of millennialsb) the popularization of smart homes.d)total globalization of the world53. what will business owners do when they become aware of the benefits of the internet of things?a）employ fewer workers in their operationsb)gain automatic control of their businessec) invest in more smart buildings and citiesd)embrace whatever new technology there is54. what is the most exciting challenge when we possess more and more data?a) how to turn it to profitable usec)how to link the actionable systemsb)how to do real time data analysisd)how to devise new ways to store it.55. what does the author think about working from anywhere and at anytime?a)it is feasible with a connection to the internetb) it will thrive in smart buildings, cities and homesc) it is still a distant utopian dream for ordinary workersd)it will deliver tangible benefits to both boss and workerPart IVTranslation (30 minutes)Directions: for this part, you are allowed 30 minutes to translate a passage from chinese into English. you should write your answer on answer sheet 2.洞庭湖位于湖南省东北部，面积很大，但湖水很浅。
