Amid all the job losses, there’s one category of worker that the economic disruption has been good for: nonhumans. From self-service checkout lines at the supermarket to industrial robots armed with saws and taught to carve up animal bodies in slaughter-houses, these ever-more-intelligent machines are now not just assisting workers but actually kicking them out of their jobs. Automation isn’t just affecting factory workers, either. Some law firms now use artificial intelligence software to scan and read mountains of legal documents, work that previously was performed by highly-paid human lawyers. “Robots continue to have an impact on blue-collar jobs, and white-collar jobs are under attack by mirs,” says economics professor Edward Leamer. The recession permanently wiped out 2.5 million jobs. U.S. gross domestic product has climbed back to pre-recession levels, meaning we’re producing as much as before, only with 6% fewer workers. To be sure, robotics are not the only job killers out there, with outsourcing (外包) stealing far more jobs than automation. Jeff Burnstein, president of the Robotics Industry Association, argues that robots actually save U.S. jobs. His logic: companies that embrace automation might use fewer workers, but that’s still better than firing everyone and moving the work overseas. It’s not that robots are cheaper than humans, though often they are. It’s that they’re better. “In some cases the quality requirements are so exacting that even if you wanted to have a human do the job, you couldn’t,” Bumstein says. Same goes for surgeons, who’re using robotic systems to perform an ever-growing list of operations—not because the machines save money but because, thanks to the greater precision of robots, the patients recover in less time and have fewer complications, says Dr. Myriam Curet. Surgeons may survive the robot invasion, but others at the hospital might not be so lucky, as iRobot, maker of the Roomba, a robot vacuum cleaner, has been showing off Ava, which could be used as a messenger in a hospital. And once you’re home, recovering, Ava could let you talk to your doctor, so there’s no need to send someone to your house. That “mobile telepresence” could be useful at the office. If you’re away on a trip, you can still attend a meeting. Just connect via videoconferencing software, so your face appears on Ava’s screen. Is any job safe? I was hoping to say “journalist,” but researchers are already developing software that can gather facts and write a news story. Which means that a few years from now, a robot could be writing this column. And who will read it?

The boy had managed to persuade his parents that the summer camp was worth _____ in.（ ）A. to participateB. participateC. participatedD. participating
The chairman has also given his ____ （approve）for an investigation into the case.
Earlier this year a series of papers in The Lancet reported that 85 percent of the 265 billion spent each year on medical research is wasted because too often absolutely nothing happens after initial results of a study are published. No follow-up investigations to replicate（复制）or expand on a discovery. No one uses the findings to build new technologies.The problem is not just what happens after publication—scientists often have trouble choosing the right questions and properly designing studies to answer them. Too many studies test too few subjects to arrive at firm conclusions. Researchers publish reports on hundreds of treatments for diseases that work in animal models but not in humans. Drug companies find themselves unable to reproduce promising drug targets published by the best academic institutions. The growing recognition that something has gone wrong in the laboratory has led to calls for, as one might guess, more research on research—attempts to find rules to ensure that peer-reviewed studies are, in fact, valid.It will take a concerted effort by scientists and other stakeholders to fix this problem. We can do so by exploring ways to make scientific investigation more reliable and efficient. These may include collaborative team science, study registration, stronger study designs and statistical tools, and better peer review, along with making scientific data widely available so that others can replicate experiments, therefore building trust in the conclusions of those studies.Reproducing other scientists' analysesor replicating their results has too often in the past been looked down on with a kind of "me-too" derision（嘲笑）that would waste resources—but often they may help avoid false leads that would have been even more wasteful. Perhaps the biggest obstacle to replication is the inaccessibility of data and results necessary to rerun the analyses that went into the original experiments. Searching for such information can be extremely difficult. Investigators die, move and change jobs; computers crash; online links malfunction. Data are sometimes lost—even, as one researcher claimed when confronted about spurious（伪造的）results, eaten by termites（白蚁）.There has definitely been some recent progress. An increasing number of journals, including Nature and Science, have adopted measures such as checklists for study design and reporting while improving statistical review and encouraging access to data. Several funding agencies, meanwhile, have asked that researchers outline their plans for sharing data before they can receive a government grant.But it will take much more to achieve a lasting culture change. Investigators should be rewarded for performing good science rather than just getting statistically significant（positive）but non-replicable results. Revising the present incentive（激励）structure may require changes on the part of journals, funders, universities and other research institutions.1What is the problem reported in those papers in The Lancet?A. Great achievements in medical research failed to get published.B. Money was wasted on follow-up investigations in medical research.C. Too many new research findings are not put into use after publication.D. Few scientists are devoted to building new technologies for mankind.2Which of the following situation is most similar to the problem described in paragraph2?A. high school decides to cut its art programs due to the lack of fund.B. patient gets sicker because he does not follow the doctor's advice.C. marketing firm tests a website with participants that are not target population.D. drug company fails to produce the new drug due to no access to the latest data.3Which of the following can be inferred from the passage? A. Measures are taken to ensure publication of tested results only.B. Scientific experiments must be replicable to be considered valid.C. Experiment replication is unoriginal and not worthwhile.D. Rewards should be given only to those non replicable findings.4The purpose of this article is to _{} .A. argue that scientific research lacks efficiencyB. explain the result of a recent scientific studyC. introduce some recent progress in medical researchD. highlight the possible problems of research studies.

The crazy cyclist was 40 kilometres into his Sunday ride when he stopped by the side of the road to text his family saying hed be home in about 30 minutes. Moments later, he was lying in the ditch, unconscious.Larissa Arthur was driving back to Calgary from a hike in Field, B.C. with a friend. It was a warm and sunny day, and the two were chatting when a flash of yellow caught Arthurs eyes. She immediately pulled off the road.As Arthur approached the figure, she feared the worst: Estepa was covered in ants and exhibited no signs of life. There was no pulse, and he wasn't breathing. says Arthur. A passer-by called 911 and Arthur, a registered nurse, started chest compressions. She and two other drivers took turns carrying out CPR for the next 15 minutes before medical teams arrived and carried Estepa away.Two days later, when Estepa woke up in the hospital, he was shocked to learn he had gone into cardiac arrest (心脏停搏). How did this happen and why was he lucky enough to have survived? He was full of gratitude and needed to speak with the woman who had saved him, whom he named his angel.It was emotional. says Arthur of her meeting with Estepa a few weeks later. Saving his life had extra importance for her: the hike she was returning from that day was one of 100 shes planned to honour her father, who died in 2017 after he fell during a hike that Arthur was meant to be on. I couldnt save my father's life, Arthur says, but this was a chance for me to save someone.24. Why did Mike Estepa stop while riding?A. He lost consciousness.B. He wanted to send a message.C.

An Angel on the Roadside4.(8分)CAn extraordinary new restaurant in Semarang, Indonesia is on a mission(使命)to support locals trapped in poverty, many of whom are earning less than 25 a month, by providing them with an alternative way to pay for their food.The Methane Gas Canteen, run by husband and wife team Sarimin and Suyatmi, is located in an unexpected place for an eatery Jatibarang Landfill. The landfill is a mountain of purifying waste, where poor locals spend their days collecting plastic and glass to sell. Meanwhile, the couple, who spent 40 years collecting waste before opening the restaurant, is busy cooking.What makes the restaurant unusual, apart from its location, is that no cash is required to pay for meals. Poor people have the option to pay for their food with recyclable waste instead of cash. Sarimin weighs the plastic customers bring in, calculates its worth, and then deduct that value from the cost of the meal, giving any extra value back to the customer. The scheme is part of the communitys solution to reduce waste in the landfill and recycle non-degradable plastics.I think we recycle 1 ton of plastic waste a day, which is a lot. This way, the plastic waste doesnt pile up, drift down the river and cause flooding, said Sarimin in an interview with Channel News Asia. It benefits everyone.The restaurant seats about 30 people and serves meals that cost between 0.40 and 0.80 each. Since opening the canteen, Sarimin and Suyatmi have seen their daily income more than double to 15 a day.Im happy to see our customers enjoying their meals, Sarimin told NHK World. The poor must also have the right to enjoy healthy eating. I want to give them that chance as much as possible.28. What do we know about Jatibarang Landfill?A. An unusual restaurant for people to eat free meals.B. A mountain where the locals live on selling waste.C. A place where poor locals collect waste to sell.D. A plant where waste is recycled.29. Why did Sarimin and Suyatmi open their restaurant?A. To double their daily income and profit.B. To prove waste is a valuable thing.C. To provide food for locals trying to survive.D. To help settle the issues of poverty and trash.30. What does the underlined word deduct in paragraph 3 mean?A. Remove B. Replace C. Increase D. Equal31. What is the text mainly about?A. An unusual way to pay for meals.B. A local mission to help get rid of poverty.C. A different scheme to reduce waste.D. A new restaurant getting double income.5.(8分)DA device called a TreeTalker is providing information about trees to people who oversee forests and woodlands. The device aims to measure the growth and general health of trees.Scientists say forests are important because they absorb, or take in, carbon dioxide, one of the gases released by burning oil and other fossil fuels. It is a heat-trapping gas and has been linked to a general warming in the Earth's atmosphere.The world is at a historic period for climate change because the scientific world is on guard. Many scientists say Be careful, the ecosystem of the forests is not able anymore, as it was before, to absorb all this carbon dioxide. Rising temperatures are placing forests under increased stress. Harmful insects and diseases are becoming more of a threat to trees. This is bad for the environment.The TreeTalker devices serve as an early warning system for people overseeing forests. TreeTalker turns eco-physiological signals, such as growth, absorption of carbon dioxide, liquid flow from roots to leaves, into scientific information. This can help show if a tree is under attack from insects or other organisms. The TreeTalker sends its information to forest managers.The TreeTalker device transmits data via radio and it can transmit data actually a very long distance, up to one kilometer. The information lets forestry officials take action immediately to control threats. The TreeTalker is able to measure the width of the bottom of a tree. Timber industry workers can use this information to know how much wood they are growing compared to how much they are harvesting. Another goal is to give scientists the information they need to understand how climate affects forests and the part trees play in a healthy environment.About 300 TreeTalker devices are being tested in Italy and other countries, such as China and Russia. Another 1,700 devices are expected to be tested worldwide this year.32. What was the TreeTalker device used for?A. Absorbing carbon dioxide.B. Providing information of forests change.C. Controlling threats from nature.D. Helping the growth and health of trees.33. Which of the following threats to forests is the most severe?A. Harmful insects and diseases. B. Forest managers.C. Carbon dioxide. D. Timber industry workers.34. What does the underlined word This in paragraph 4 refer to?A. The information of an early warning system.B. The information on the absorption of carbon dioxide.C. The information of eco-physiological signals.D. The information to the forest managers.35. Whats the authors attitude towards the TreeTalker device?A. Understanding B. Alarming.C. Doubting. D. Promising.

question or statement.Hot pot is a traditional dish in China. It is believed to date back more than 1,000 years to the time of the Jin Dynasty. Hot pot's origins can be found in the dining practices of Mongolian horsemen who rode across the steppe and into northern China. Legend has it that the Mongols used their helmets as pots to simmer (炖) broth (汤底) over open fires, and cooked chunks of meat in the broth.Hot pot cooking seems to have spread to northern China during the Tang Dynasty. In the regional variations developed with different ingredients such as seafood. In the centuries that witnessed the growth of the Song Dynasty, hot pot moved — and changed — further south, with each successive region adapting it to their local ingredients and tastes.The ingredients in a hot pot vary a lot from region to region. Perhaps the most famous hot pot is the Chongqing or Sichuan hot pot. It features a dark red broth chock-full (塞满了的) of spices, chili peppers, and the uniquely mouth-numbing Sichuan peppers. In Beijing and elsewhere in the north, hot pot broth tends to be mild and, compared to its racy southern "cousins", a little light. In the northeast of China, a kind of local sauerkraut (酸菜) is used to add some tang (强烈的味道), making the broth a bit sour. People can choose a version of hot pot according to their taste.1 Hot pot is believed to date back more than 1,000 years to the time of _______.A. the Jin Dynasty B. the Tang DynastyC. the Song Dynasty D. the Yuan Dynasty

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.

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. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.
