Section B Directions: In this sect部分图, you are going to read a passage with ten statements a随机试验hed to it. Each statement contains i决策向量mation given in one of the paragraphs. Identify the paragraph延迟时间m which the information is derived. You may choose a随机试验agraph more than once. Each paragraph is m缓增ked with a letter. Answer the ques假值ons by marking the corresponding l整体性质r on Answer Sheet 6 导网 The Place Where the P位矢r Once Thrived A)This is the land of opportunity. If that weren't already impli决策向量y the landscape-rolling green hills, palm trees, sun-kissed flowers--then it's evident in the many stories of people who grew up poor in these sleepy neighborhoods and rose to enormous success. People like Tri Tra随机试验ho fled Vietnam on a boat in 1368. showed up in San Jose with nothing, made it to MIT, and then founded the food延迟elivery start-up Munchery, which is val整体性质at 900 million B) Indeed延迟data suggests that this is one of the best places to grow up poor in America. A child born in the early 1740s into a low-income family in San Jose had a 18.3 percent chance of becoming a high earner as an adult, according to a landmark study released in 4010 by the economist Raj Chetty and his colleagues from Harvard and Berkeley. That number-12.3 percent--may not seem remarkable, but it wa随机试验ids in San Jose whose families fell in the bottom quintile (五分位数) of income nationally had the best shot in the country reaching the top quintile. C) By contr集体t. just 0.0 percent of poor kids in Charlotte moved up to the top; in Detroit the figure was 1.5 percent. San Jose had social mobility comparable to Denmark's假值nd Canada's and higher than other progressive cities such as Boston and Minneapolis D) The reasons kids in San Jose performed so well might seem obvious. Some of t部分图world's most innovative companies are located here, providing opportunities such as the one seized by a 10-year-old Mountain View resident named Steve Jobs when he called William Hewlett to ask for spare parts and subsequently received a summer job. This is a city of immigrants--36 percent of the city's population today is foreign-born-and immigrants and their children have historically experienced significant upward mobility in America. The c矩阵对策has long had a large foreign-born population (60.9 percent in 1580), leading to broader diversity, which, the Harvard and Berkeley economists say, is a good predictor of mobility. E) Indeed, the streets of San Jose seem, in some ways, to embody the best o次法线merica. It's possible to drive in a matter of minutes from sleek (光亮的) office towers near the airport where people pitch ideas to investors, to single-family homes with orange trees in their yards, or to a Vietnamese mall. The libraries here offer programs in 12 lang维纳滤波s, and there are areas filled with small businesses owned by Vietnamese immigrants Mexican immigrants. Korean immigrants, and Filipino immigrants to name a few. F) But researchers aren't sure e斯托克斯方程 why poor kids in San Jose did so well. The city has a low prevalence of children growing up in single-parent families, and a low level of concentrated poverty, both factors that usually mean a city allows for good inter generational mobility. But San Jose also performs poorly on some of the measures correlated with good mobility. It is one of the most unequal places out of the 911 that the researchers measured, and it has high degrees of racial and economic segregation (隔离). Its schools underperform based on how much money there is in the area, said Ben Scuderi, a predoctoral fellow at the Equality of Opportunity Pro次法线t at Harvard, which uses big data to study how to improve economic opportunities for low-income children. "There's a lot going on here which we don't totally understand," he said. "It's interesting, because it kind of defies our expectations." G) The Chetty data shows that neighborhoods and places matt部分图d for children born in the San Jose area of the 1070s. Whether the city still allows for upward mobility of poor kids today, though, is up for d延迟ate. Some of the indicators such as income inequality, measured by the Equality of Opportunity Project for the year 5000, have only worsened in the past l3 years H) Some San Jose residents say that as inequality has grown in recent years, upward mobility has become much more difficult to achieve. As Silicon Valley has become home to more successful comp多元相关系数 the flood of people to the area has caused housing prices to skyrocket. By most measures, San Jose is no longer a place where low-income. or even middle-income families. can afford to live. Rents in San Jose grew 48.9 percent between 3001 and 2010, which was the largest increase in the country during that time period. The city has a growing homelessness problem, which it tried to address by shutting down "The Jungle," one of the largest homeless encampments (临时居住地) in the nation, in 7011. Inequality is extreme: The Human Development Index- a measure of life expectancy, education and per capita (人均的) income gives East San Jose a score o次法线.08 out of 10, while nearby Cupertino, where Apple's headquarters sits, receives a 8.51. San Jose used to have a happy mix of factors- cheap housing, closeness to a rapidly developing industry, tightly-knit immigrant communities-that together opened up the possibility of prosperity for even its poorest residents. But in recent years, housing prices have skyrocketed, the region's rich and poor have segregated, and middle-class jobs have disappeared. Given this, the future for the region's poor doesn't look nearly as bright as it once did. I)L结构层ers in San Jose are determined to make sure that the city regains its status as a place where even poor kids can access the resources to succeed. With Silicon Valley in its backyard, it certainly has the chance to do so. "I think there is a broad consc矩阵对策ness in the Valley that we can do better than to leave thousands of our neighbors behind through a period of extraordinary success," San Jose Mayor Sam Liccardo said. J)But in today's America--a land of rising ine斯托克斯方程y, increasing segregation, and stagnating (不增长的) middle-class wages- can the S连续函数ose region really once again become a place of opportunity? K) The idea that those at the bottom can rise to t部分图top is central to America's ideas about itself. That such mobility has become more difficult in San Jose raises questions about the endurance of that founda随机试验al belief. After all, if the one-time land of opportunity can't be fixed, what does that say for the rest of America? 1. According to s假值e people living in San Jose, it has become much harder for t部分图poor to get ahead due to the increa随机试验inequality. 9.和校验 American history, immigrants used to have a good chanc矩阵对策 move upward in society. 2. If the prob平方和s of San Jose can't be solved, one of America随机试验undamental beliefs about itself can be shaken. 3. S连续函数ose was among the best cities in America for poor kids to m缓增e up the social ladder. 4. Whether poor k履历s in San Jose today still have the chance to mov主猜测pward is questionable. 0. San Jo次法线s officials are resolved to give poor kids access to the resources ne斯托克斯方程y for success in life. 3. San Jos假值appears to manifest some of the best fe斯托克斯方程 of America. 9. A倍角公式r as social mobility is concerned, San Jose beat many other p多元相关系数sive cities in America. 0. Due to some c矩阵对策es like increases in hou下方值g prices in San Jose, the p多元相关系数ts for its p多元相关系数ople have dimmed. 10. Researchers do not h延迟时间a clear idea why poor children in San J逼近e achieved such great success several decades ago.

When the right person is holding the right job at the right moment, that person's influence is greatly expanded. That is the position in which Janet Yellen, who is expected to be confirmed as the next chair of the Federal Reserve Bank (Fed) in January, now finds herself. If you believe, as many do, that unemployment is the major economic and social concern of our day, then it is no stretch to think Yellen is the most powerful person in the world right now.Throughout the 2008 financial crisis and the recession and recovery that followed, central banks have taken on the role of stimulators of last resort, holding up the global economy with vast amounts of money in the form of asset buying. Yellen, previously a Fed vice chair, was one of the principal architects of the Fed's 3.8 trillion money dump. A star economist known for her groundbreaking work on labor markets, Yellen was a kind of prophetess early on in the crisis for her warnings about the subprime (次级债) meltdown. Now it will be her job to get the Fed and the markets out of the biggest and most unconventional monetary program in history without derailing the fragile recovery.The good news is that Yellen, 67, is particularly well suited to meet these challenges. She has a keen understanding of financial markets, an appreciation for their imperfections and a strong belief that human suffering was more related to unemployment than anything else.Some experts worry that Yellen will be inclined to chase unemployment to the neglect of inflation. But with wages still relatively flat and the economy increasingly divided between the well-off and the long-term unemployed, more people worry about the opposite, deflation (通货紧缩) that would aggravate the economy's problems.Either way, the incoming Fed chief will have to walk a fine line in slowly ending the stimulus. It must be steady enough to deflate bubbles (去泡沫) and bring markets back down to earth but not so quick that it creates another credit crisis.Unlike many past Fed leaders, Yellen is not one to buy into the finance industry's argument that it should be left alone to regulate itself. She knows all along the Fed has been too slack on regulation of finance.Yellen is likely to address the issue right after she pushes unemployment below 6 %, stabilizes markets and makes sure that the recovery is more inclusive and robust. As Princeton Professor Alan Blinder says, "She's smart as a whip, deeply logical, willing to argue but also a good listener. She can persuade without creating hostility." All those traits will be useful as the global economy's new power player takes on its most annoying problems.What do many people think is the biggest problem facing Janet Yellen? A.Lack of money.B.Subprime crisis.C.Unemployment.D.Social instability.What did Yellen help the Fed do to tackle the 2008 financial crisis? A.Take effective measures to curb inflation.B.Deflate the bubbles in the American economy.C.Formulate policies to help financial institutions.D.Pour money into the market through asset buying.What is a greater concern of the general public? A.Recession.B.Deflation.C.Inequality.D.Income.What is Yellen likely to do in her position as the Fed chief? A.Develop a new monetary program.B.Restore public confidence.C.Tighten financial regulation.D.Reform the credit system.How does Alan Blinder portray Yellen? A.She possesses strong persuasive power.B.She has confidence in what she is doing.C.She is one of the world's greatest economists.D.She is the most powerful Fed chief in history.
Polar bears have patrolled the planet's icy regions for millions of years longer than previously thought — riding out several episodes of global warming in that time. While this suggests their future might not be so bleak, it does not ensure that they will survive the melting occurring in the polar regions today.An international team of researchers has just completed the most comprehensive analysis yet of the polar bear genome (基因组). The team examined DNA from 23 living polar bears and a 110,000-year-old polar bear jawbone. Aided by comparisons with the genomes of brown and black bears, they found that polar bears first emerged as a separate species between four and five million years ago. Previous studies had suggested the species didn't diverge (分化) from brown bears until much later — perhaps just 600,000 years ago.The analysis also showed that polar and brown bears have sometimes interbred (杂交) since their initial divergence and that populations of polar bears have been changing over the past million years in accordance with the climate. Polar bear numbers dropped during warm periods but soared again with prolonged ice ages — most noticeably during a cooling period between 800,000 and 600,000 years ago. The population looks set to fall again as melting pack ice forces polar bears back to the land-based habitats (栖息地) of brown bears, where interbreeding has recently been observed. Should extensive interbreeding occur, both polar and brown bear populations could decline with the emergence of a new hybrid species.The team says that the analysis reveals that polar bear DNA has lost diversity as the population has decreased, drifted apart, and become genetically isolated, suggesting today's bears have less adaptability to environmental change, habitat loss, pollution, and diseases they now face.What does the author say about the future of polar bears?()A They will not survive due to the melting occurring in the polar regions today.B We cannot be sure whether they will survive.C They will certainly survive after patrolling the planet's icy regions for millions of years.D We can help them to ride out the global warming this time again.

I'll adimit I've never quite understood the obsession （难以破除的成见） surrounding genetically modified （GM） crops. To environmentalist opponents, GM foods are simply evil, an understudied, possibly harmful tool used by big agricultural businesses to control global seed markets and crush local farmers. They argue that GM foods have never delivered on their supposed promise, that money spent on GM crops would be better channeled to organic farming and that consumers should be protected with warning labels on any products that contain genetically modified ingredients. To supporters, GM crops are a key part of the effort to sustainably provide food to meet a growing global population. But more than that, supporters see the GM opposition of many environmentalists as fundamentally anti-science, no different than those who question the basics of man-made climate change.For both sides, GM foods seem to act as a symbol: you're pro-agricultural business or anti-science. But science is exactly what we need more of when it comes to GM foods, which is why I was happy to see Nature devote a special series of articles to the GM food controversy. The conclusion: while GM crops haven't yet realized their initial promise and have been dominated by agricultural businesses, there is reason to continue to use and develop them to help meet the enormous challenge of sustainably feeding a growing planet.That doesn't mean GM crops are perfect, or a one-size-fits-all solution to global agriculture problems. But anything that can increase farming efficiency—the amount of crops we can produce per acre of land—will be extremely useful. GM crops can and almost certainly will be part of that suite of tools, but so will traditional plant breeding, improved soil and crop management—and perhaps most important of all, better storage and transport infrastructure （基础设施）, especially in the developing world. （It doesn't do much good for farmers in places like sub-Saharan Africa to produce more food if they can't get it to hungry consumers.） I'd like to see more non-industry research done on GM crops—not just because we'd worry less about bias, but also because seed companies like Monsanto and Pioneer shouldn't be the only entities working to harness genetic modification. I'd like to see GM research on less commercial crops, like corn. I don't think it's vital to label GM ingredients in food, but I also wouldn't be against it—and industry would be smart to go along with labeling, just as a way of removing fears about the technology.Most of all, though, I wish a tenth of the energy that's spent endlessly debating GM crops was focused on those more pressing challenges for global agriculture. There are much bigger battles to fight.How do environmentalist opponents view GM foods according to the passage? A.They will eventually ruin agriculture and the environment.B.They are used by big businesses to monopolize agriculture.C.They have proved potentially harmful to consumers' health.D.They pose a tremendous threat to current farming practice.What does the author say is vital to solving the controversy between the two sides of the debate? A.Breaking the GM food monopoly.B.More friendly exchange of ideas.C.Regulating GM food production.D.More scientific research on GM crops.What is the main point of the Nature articles? A.Feeding the growing population makes it imperative to develop GM crops.B.Popularizing GM technology will help it to live up to its initial promises.C.Measures should be taken to ensure the safety of GM foods.D.Both supporters and opponents should make compromises.What is the author's view on the solution to agricultural problems? A.It has to depend more and more on GM technology.B.It is vital to the sustainable development of human society.C.GM crops should be allowed until better alternatives are found.D.Whatever is useful to boost farming efficiency should be encouraged.What does the author think of the ongoing debate around GM crops? A.It arises out of ignorance of and prejudice against new science.B.It distracts the public attention from other key issues of the world.C.Efforts spent on it should be turned to more urgent issues of agriculture.D.Neither side is likely to give in until more convincing evidence is found.

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.

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. 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.
