The AlphaGo program's victory is an example of how smart computers have become.But can artificial intelligence（AI）machines act ethically，meaning can they be honest and fair？ One example of AI is driverless cars.They are already on California roads，so it is not too soon to ask whether we can program a machine to act ethically.As driverless cars improve，they will save lives.They will make fewer mistakes than human drivers do.Sometimes，however，they will face a choice between lives.Should the cars be programmed to avoid hitting a child running across the road，even if that will put their passengers at risk？What about making a sudden turn to avoid a dog？What if the only risk is damage to the car itself，not to the passengers？ Perhaps there will be lessons to learn from driverless cars，but they are not super-intelligent beings.Teaching ethics to a machine even more intelligent than we are will be the bigger challenge. About the same time as AlphaGo's triumph，Microsoft's 'chatbot' took a bad turn.The software，named Taylor，was designed to answer messages from people aged 18-24.Taylor was supposed to be able to learn from the messages she received.She was designed to slowly improve her ability to handle conversations，but some people were teaching Taylor racist（种族主义的）ideas.When she started saying nice things about Hitler，Microsoft turned her off and deleted（删除）her ugliest messages. AlphaGo's victory and Taylor's defeat happened at about the same time.This should be a warning to us.It is one thing to use AI within a game with clear rules and clear goals.It is something very different to use AI in the real world.The unpredictability of the real world may bring to the surface a troubling software problem. Eric Schmidt is one of the bosses of Google，which owns AlphaGo.He thinks AI will be positive for humans.He said people will be the winner，whatever the outcome.Advances in AI will make human beings smarter，abler and "just better human beings."（1）What does the author want to show with the example of AlphaGo's victory？ ____ A.Computers will defeat human beings.B.Computers can become highly intelligent.C.omputers have unmatched potential.D.Computers are man's potential rivals.（2）What does the author mean by AI machines acting ethically？ ____ A.They are capable of predicting possible risks.B.They weigh the gains and losses before reaching a decision.C.They sacrifice everything to save human lives.D.They make right decisions when facing moral dilemmas.（3）What is said to be the bigger challenge facing humans in the AI age？ ____ A.How to ensure that super-intelligent AI machines act ethically.B.How to make super-intelligent AI machines share human feelings.C.How to prevent AI machines doing harm to humans.D.How to avoid being over-dependent on AI machines.（4）What do we learn about Microsoft's "chatbot" Taylor？ ____ A.She could turn herself off when necessary.B.She was not made to handle novel situations.C.She could not distinguish good from bad.D.She was good at performing routine tasks.（5）What does Eric Schmidt think of artificial intelligence？ ____ A.It will be far superior to human beings.B.It will keep improving as time goes by.C.It will be here to stay whatever the outcome.D.It will prove to be of value to human beings.
Only two countries in the advanced world provide no guarantee for paid leave from work to care for a newborn child． Last spring one of the two， Australia， gave up the dubious distinction by establishing paid family leave starting in 2011． I wasn't surprised when this didn't make the news here in the United States-we're now the only wealthy country without such a policy． The United States does have one explicit family policy， the Family and Medical Leave Act， passed in 1993． It entitles workers to as much as 12 weeks' unpaid leave for care of a newborn or dealing with a family medical problem． Despite the modesty of the benefit， the Chamber of Commerce and other business groups fought it bitterly， describing it as "government-run personnel management" and a "dangerous precedent"． In fact， every step of the way， as （usually） Democratic leaders have tried to introduce work-family balance measures into the law， business groups have been strongly opposed． As Yale law professor Anne Alstott argues， justifying parental support depends on defining the family as a social good that， in some sense， society must pay for． In her book No Exit： What Parents Owe Their Children and What Society Owes Parents， she argues that parents are burdened in many ways in their lives： there is "no exit" when it comes to children． "Society expects-and needs-parents to provide their children with continuity of care， meaning the intensive， intimate care that human beings need to develop their intellectual， emotional and moral capabilities． And society expects-and needs-parents to persist in their roles for 18years， or longer if needed．" While most parents do this out of love， there are public penalties for not providing care． What parents do， in other words， is of deep concern to the state， for the obvious reason that caring for children is not only morally urgent but essential for the future of society． The state recognizes this in the large body of family laws that govern children' welfare， yet parents receive little help in meeting the life-changing obligations society imposes． To classify parenting as a personal choice for which there is no collective responsibility is not merely to ignore the social benefits of good parenting； really， it is to steal those benefits because they accrue （不断积累） to the whole of society as today's children become tomorrow's productive citizenry （公民）． In fact， by some estimates， the value of parental investments in children， investments of time and money （including lost wages）， is equal to 20-30% of gross domestic product． If these investments generate huge social benefits-as they clearly do-the benefits of providing more social support for the family should be that much clearer． 65． What do we learn about paid family leave from the first paragraph？ A． America is now the only developed country without the policy． B． It has now become a hot topic in the United States． C． It came as a surprise when Australia adopted the policy． D． Its meaning was clarified when it was established in Australia． 66． What has prevented the passing of work-family balance laws in the United States？ A． The incompetence of the Democrats． B． The existing Family and Medical Leave Act． C． The lack of a precedent in American history． D． The opposition from business circles． 67． What is Professor Anne Alstott's argument for parental support？ A． The cost of raising children in the U． S． has been growing． B． Good parenting benefits society． C． The U． S． should keep up with other developed countries． D． Children need continuous care． 68． Which of the following is closest in meaning to the underlined word "dubious" in paragraph one？ A． Special B． Significant C． Alleged D． Thorough 69． What does the author think of America's large body of family laws governing children's welfare？ A． They fail to ensure children's healthy growth B． The fail to provide enough support for parents C． They emphasize parents' legal responsibilities． D． They impose the care of children on parents． 70． Why does the author object to classifying parenting as a personal choice？ A． It is regarded as a legal obligation． B． It relies largely on social support． C． It generates huge social benefits． D． It is basically a social undertaking．
Passage Two Questions 51 to 55 are based on the following passage. If there's one rule that most parents cling to in the confusing, fast-changing world of kids and media, it's “No screens before age 2.” As of today, that rule has been thrown out the window. The American Academy of Pediatrics (AAP), which first issued that recommendation back in 1999, has extensively updated and revised its guidelines for children and adolescents to reflect new research and new habits. The new guidelines, especially for very young children, shift the focus from WHAT is on the screen to WHO else is in the room. And in doing so, they raise some intriguing points about the future of learning from media. For babies younger than 18 months, AAP still says no screens at all are the best idea—with one notable exception: Live video chat. Surveys indicate that families already popularly believe that “Face time doesn't count”, or at least that the benefit of virtual visits with grandparents or other relatives outweighs the potential cost of exposing babies to the laptop or smartphone. The AAP doesn't cite positive evidence that infants actually get something out of this kind of “conversation”, the way that they clearly do from live social interaction. But there's some observational research that infants as young as six months old are emotionally engaged by playing live peekaboo (躲猫猫) with Grandma online. For infants and toddlers (学步儿童), ages 15 months to 2 years old, there's limited evidence from a couple of very small studies that they can learn new words from educational media, if and only if parents are watching alongside them, repeating what the video says and/or drawing attention to what is on the screen. In other words, treating a video or an app like a picture book is the best bet. The flip side of this is that many studies have actually shown poorer language skills correlated with earlier solo viewing of “educational” videos. There's also research that shows language delays in children who watch more TV and start watching earlier. In both cases, the problem seems to be media replacing interaction with people. Forth is reason, the new AAP guideline has changed from “avoid all screens under age 2 “to “avoid solo media use in this age group.” For preschoolers ages 2 to 5, there's more evidence that they have the ability to transfer knowledge from screens to the real world, including early literacy and math. For this age group, AAP recommends no more than an hour a day of screen use. And, just as with younger children, they want care-givers to take part in screen time: “Co-view with your children, help children understand what they are seeing, and help them apply what they learn to the world around them.” 51. What do we learn about the "No screens under 2" rule?A) It has met more and more resistance from parents.B) It has proved helpful to children's healthy growth.C) It confuses parents with regard to kids' education.D) It has been discarded in line with recent research. 52. What do the new AAP guidelines advocate?A) Young children should be accompanied by parents during screen time.B) Parents should be emotionally involved in their children's upbringing.C) Young children should watch videos carefully selected by parents.D) Parents should protect their children from too much media exposure. 53. What do families think of live video chat according to surveys?A) It should not be regarded as screen time.B) It helps babies to develop their verbal skills.C) It is not as harmful as playing games on laptops.D) It is a good substitute for video viewing. 54. What do researches find about kids solo viewing educational videos?A) It arouses their interest in language learning.B) It works no better than reading picture books.C) It hampers their development of language skills.D) It helps them acquire independent learning skills. 55. What does the author say about preschoolers ages 2 to 5?A) They can understand pretty well what they see on the screen.B) They can learn on their own without much parental guidance.C) They can make use of educational videos to develop digital literacy.D) They can relate what they learn on the screen to real life situations.

Here are nine fail-proof (奏效的) ways to ensure your family’’s financial well-being. What to Do Today "Your dad’’s in a bad way. You’’d better come home immediately." In the days and months after Catherine Fredman got the phone call from her father’’s neighbor, the self-employed writer and her sister, a college professor, agonized (感到苦恼) over their father’’s medical condition and treatment choices. But they never had to worry about compromising his care because of the cost. "Thank goodness my father had bought long-term-care insurance," Fredman says. "He was in hospitals and rehab facilities (康复中心)for eight months recovering from Lyme disease. The long-term-care insurance paid more than 20,000 that would not have been covered by Medicare and his supplemental health insurance." It’’s never too early to protect your family’’s financial well-being. Yet because most of us are so busy juggling work and family commitments, we tend to neglect the things that don’’t require immediate attention. Some day, we think, we’’ll take care of the three essentials―retirement savings, insurance coverage and estate planning. Unfortunately, emergencies can strike and then it’’s too late. "Failure to plan is a huge mistake," Barbara Raasch, managing director at Wealth and Tax Advisory Services, Inc. , told me. How can you avoid the "should have, could have, would have" scenario By putting these three items at the top of your "to do" list―protect your future, protect your family and protect your legacy. Protect Your Future The national savings rate averaged around 0.4% for the first half of 2005, according to the U.S. Department of Commerce, meaning Americans spent a whopping 99.6% of their after-tax earnings. Even more frightening, in July the savings rate dropped below zero. We all know we should save more. But with so many goals to save for―a house, the kids’’ college tuition, your retirement, occasional vacations and a small emergency fund―it’’s easy to feel there’’s just not enough money to do it all. 1. Budget. The first step is to create a budget. Once you know what you’’re spending your money on, you can figure out what you don’’t need to spend it on―and sock those savings away. "Every month you have to pay yourself first," says Joe Moglia, CEO of Ameritrade. "Take a little out of your paycheck. " It doesn’’t have to be much―it could be foregoing that extra latte or getting the DVD free at the library. 2. Retirement. Just about every survey of American investors these days shows that retirement is a main reason for saving. Yet an astounding number of people ignore the opportunities offered by employment-based retirement plans. According to a recent survey by Aon Consulting, more than 20% of those eligible for a 401k plan do not participate at all, while another 53% do not save at a rate high enough to take full advantage of their employers’’ matching contribution―the closest thing to free money in the retirement savings universe. Consider it money that grows without being taxed. 3. Emergency reserves. Many financial planners recommend that you have enough money in a savings or money-market account for at least six to nine months of essential expenses, including your mortgage or rent, insurance premiums, credit card payments, utility and grocery bills and other fixed expenses, such as car payments or student loans. And it’’s always a good idea to have cash on hand. During the blackout of 2003, the ATMs in my neighborhood were out, but we had about 500 in the house, enough to cover our immediate needs for a week or so. Protect Your Family A major illness, an extended disability or the loss of a job could wipe out your financial reserves and any prospect of being able to save enough to achieve your other life goals. Here’’s what you need to protect your savings: 4. Health insurance. A recent study of court records and direct interviews indicated that about half of personal bankruptcies in the U.S. are caused in part by medical debts. A relative of mine is about to have her hip replaced and because she’’s over 65. Medicare is paying for it. But people under that age face enormous bills―when a child needs an appendectomy, for instance―and many of them lack insurance. A doctor in New York told me he recently performed heart bypass surgery on a 30-year-old man. His total bill, including surgery and the 10-day stay, came to 100,000. Luckily his insurance covered it. If your company provides medical benefits, you have the most cost-efficient (节省成本的) coverage available. Sign up. If you’’re responsible for your own medical insurance, you may want to look into Health Savings accounts (HSAs), a combination of a high deductible health plan and a tax-deductible savings account allocated to health care expenses. The funds in the account grow tax-free and can be withdrawn tax-free to pay for any qualified medical expenses, including over-the-counter medications, dental care, eyeglasses and other costs not usually covered by conventional health insurance plans. 5. Disability insurance. Over 80% of Americans don’’t have adequate disability coverage, according to a survey by the Consumer Federation of America and the American Council of Life Insurers. You may already have disability insurance through your employee benefits plan, either as paid sick leave or actual disability payments if you’’re unable to work for an extended period of time. But these programs tend to pay far less than your weekly salary. For the self-employed, having a financial safety net is even more crucial. 6. Life insurance. If you die prematurely, a life-insurance policy will provide immediate funds for funeral expenses, and may help replace your lost income. "Life insurance isn’’t a priority if you are single, but if you have a spouse or dependents, you want to make sure they’’re taken care of," says Barbara Raasch. Employers frequently offer coverage as part of their benefits package. Protect Your Legacy One of the most thoughtful legacies that anyone can leave is peace of mind. No one wants to mar the memory of a loved one with "I think this is what Mom wanted but she never said doubts". You can prevent that with the right advance directives and documents: 7. A will (遗嘱). Over half of the adult population in this country dies without a will. This is not just senseless; it’’s downright irresponsible. If you die intestate, or without a will, says Karin Barkhom, an estate planning attorney at Bryan Cave LLP, "the state determines how your assets are dispersed. " What’’s more, the government could end up collecting a lot more tax than necessary. 8. A living will. Also known as a health care directive, a living will specifies what medical measures should be used to keep you alive if you are incapacitated. Quiet a few agonizing cases have showed how the absence of a living will can rip a family apart. Health care providers are generally required to comply with the wishes you describe in your living will. 9. Durable power of attorney. This document authorizes a loved one to make Financial decisions on your behalf should you become unable. It allows someone to renew your CD at the bank, pay bills, sell stock or even sell your home or business, based on the agent’’s determination of what is best for you. " If you are in the hospital and cannot pay your bills or sign a check, someone will have to do it," says Raasch. "If any of your assets are held in your name only, your spouse can’’t touch that money unless the court appoints him guardian. The emotional turmoil of your loved ones having to go to court will only add to your misery. " Although it’’s best to have these documents prepared by a family-law attorney, you can cover the basics on your own with certain computer software programs. Retirement savings. Insurance coverage. Estate planning. These are the foundations of a financial well-being plan. Take care of your family and yourself today.Health Savings Accounts offer you the most cost-efficient medical coverage.

Time spent in a bookshop can be most enjoyable, whether you are a book lover or you are merely there to buy a book as a present. You may even have entered the shop just to find shelter from a sudden shower. Whatever the reason, you can soon become totally unaware of your surroundings. The desire to pick up a book with an attractive dust jacket (书的护封)is irresistible, although you might end up with a rather dull book. This opportunity to escape the realities of everyday life is, I think, the main attraction of a bookshop. You can wander round such places to your heart's content. If it is a good shop, no assistant will approach you with the greeting—"Can I help you, sir?" You needn't buy anything you don't want. In a bookshop, an assistant should remain in the background until you have finished browsing (浏览). You may want to find out where a particular section is. Then, and only then, are his/her services necessary. But when he/she has led you there, the assistant should leave politely and look as if he/she is not interested in selling a single book. It is very easy to enter the shop looking for a book on ancient coins and come out carrying a copy of the latest best-selling novel. Apart from running up a huge account, you can waste a great deal of time wandering from section to section. According to the author, a bookshop is popular mainly because _______. A people can shelter from the rain B most people are book lovers C people might have the opportunity to escape the realities of everyday life D people can choose a book as a gift

The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. [共5题](1)What kind of manager is needed in present international business and foreign investment? [本题2分]A. The man who represents a large multi-million-dollar corporation. B. The man with knowledge of foreign languages and skills in cross-cultural communication. C. The man who is wealthy and impersonal. D. The man who can negotiate with his foreign counterparts.

If the father says he hates fat meat or the mother refuses vegetables in the child’s hearing he is (54) to copy this procedure. Take it (55) granted that he likes everything and he probably will. Nothing healthful should be omitted from the meal because of a (56) dislike. At meal times it is a good idea to give a child a small portion and let him (57) back for a second helping rather than give him as much as he is likely to eat all at once.

Americans experience more food recalls (召回) today than they did five years ago, especially when it comes to meat and poultry (家禽). Meat and poultry recalls increased by two-thirds from 2013 to 2018, while food recalls overall went up 10%, according to the report recently published by the U.S. Public Interest Research Group.Meanwhile, the U.S. Centers for Disease Control and Prevention estimates (估计) 48 million people get sick, 128,000 are hospitalized and 3,000 die from food-borne disease each year in the U.S. "We are looking for the farm-to-fork preventative solutions," said Adam Garber, the research group's consumer watchdog. "By doing that, we can protect people's health."Over the five-year period, poultry posted the most recalls (168), followed by beef (137) and pork (128). The report shows the most serious meat recalls are on the rise. Among meat and poultry, the number of Class I recalls has increased by 83%, nearly doubling. Class I, the most serious of the recalls, is issued when there is a reasonable probability that the food will cause health problems or death.53. When would Class I recalls be issued?A. When the food is likely to cause health problems or death.B. When there are too many complaints from customers.C. When the food problem lasts for five years.D. When the product quality is below standard.

The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers.
