问答题John Kenneth Galbraith, the iconoclastic economist, teacher and diplomat, died Saturday at a hospital in Cambridge, Massachusetts. He was 97. Mr. Galbraith was one of the most widely read authors in the history of economics; among his 33 books was "The Affluent Society" (1958), one of those rare works that forces a nation to re-examine its values. He wrote fluidly, even on complex topics, and many of his compelling phrases—among them "the affluent society," "conventional wisdom" and "countervailing power"—became part of the language. An imposing presence, lanky and angular at 6 feet 8 inches tall, Mr. Galbraith was consulted frequently by national leaders, and he gave advice freely, though it may have been ignored as often as it was taken. Mr. Galbraith clearly preferred taking issue with the conventional wisdom he distrusted. Mr. Galbraith, a revered lecturer for generations of Harvard students, nonetheless always commanded attention. From the 1930"s to the 1990"s Mr. Galbraith helped define the terms of the national political debate, influencing both the direction of the Democratic Party and the thinking of its leaders. He tutored Adlai E. Stevenson, the Democratic nominee for president in 1952 and 1956, on Keynesian economics. He advised President John E Kennedy (often over lobster stew at the Locke-Ober restaurant in their beloved Boston) and served as his ambassador to India. Though he eventually broke with President Lyndon B. Johnson over the war in Vietnam, he helped conceive of Mr. Johnson"s Great Society program and wrote a major presidential address that outlined its purposes. In 1968, pursuing his opposition to the war, he helped Senator Eugene J. McCarthy seek the Democratic nomination for president. In the course of his long career, he undertook a number of government assignments, including the organization of price controls in World War II and speechwriting for Presidents Franklin D. Roosevelt, Kennedy and Johnson. He drew on his experiences in government to write three satirical novels. He took on the Harvard economics department with "A Tenured Professor," ridiculing, among others, a certain outspoken character who bore no small resemblance to himself. At his death, Mr. Galbraith was the emeritus professor of economics at Harvard, where he had taught for most of his career. A popular lecturer, he treated economics as an aspect of society and culture rather than as an arcane discipline of numbers.

问答题日前，腾讯老大马化腾坦言“腾讯目前只是在国内有很多用户和较高的知名度，但在国外没有多少人知道”。 事实的确如此。 微信在国内雄霸4亿用户之时，高调推出国际化战略之后的微信海外用户却仅有5000万，其海外战略进展却不如意。 以日本为例，使用WeChat(微信的海外版本)的人大多数是华人。据报道，在日本工作的华人做了调研，结论是“不接地气”：比如日本人非常警惕通过“搜索”找上门来的“朋友”，对于Look Around功能，也就是在国内微信中类似“附近的人”这一功能十分排斥；比如，日本人没有QQ情节，对于WeChat从QQ移植过来的表情感觉非常奇怪：再比如，WeChat没有游戏一说，在游戏产业风靡的日本，只能靠边站了。 韩国有Kakao Talk、日本有LINE，微信发力东南亚市场，劲敌强大。而微信国际化的关键在于能否进入欧美市场尤其是美国市场。 但是，在美国占有一席之地，更难。 美国作为全球互联网科技创新的发源地，WhatsApp、Facebook Messenger都是十分成熟的产品，尤其是面对拥有超过10亿用户的Facebook，微信如何建立先进的产品认知?微信在产品功能上的新鲜价值如何复制到美国市场?还有，微信在国内有QQ的庞大用户群“背书”，但在美国显然没有背后的用户群，人口问题实在紧迫。 不仅如此，此前，中国大型互联网公司几乎没有谁敢进入美国市场，因为面临从语言到数据安全顾虑等一系列挑战。去年奥巴马政府公布的《隐私人权法案》，进一步约束互联网及移动互联网企业需要谨慎处理用户的隐私信息。可以想见，微信要获得美国用户的信赖，并非易事。 互联网的兴盛促成了地球村时代的到来，尽管沟通再无地理上的障碍，但是隔阂仍然存在，包括文化差异、用户沟通交流习惯不同、数据安全等一系列问题。Google败走亚洲：在日本不及雅虎、在韩国输给Naver；Facebook席卷世界，却在巴西惨败给Google旗下几近放弃的社交网站Orkut；盛大在纳斯达克上市8年，最终选择黯然退市……这些都是扩张型互联网企业在全球化视角下的战略困局。 在中国，除了阿里巴巴背靠国际贸易的市场环境走出国门之外，有实力将产品拿到国外市场的，百度算是第二个，微信是第三个。可遗憾的是，中国互联网企业“成功”迈向国际的模式还没有，微信只有“摸着石头过河”了。

问答题{{B}}Passage 2{{/B}} {{B}}A Different Consensus{{/B}} Even as the U.S. Senate debates a vast new tax and spend regime in the name of fighting climate change, a more instructive argument was taking place in Copenhagen, Denmark. Some of the world's leading economists met earlier this month to decide how to do the most good in a world of finite resources. Scarcity is a core economic concept. There isn't an unlimited amount of money to be spent on every problem, so choices have to be made. The question addressed by the Copenhagen Consensus Center is what investments would do the most good for the most people. The center's blue-ribbon panel of economists, including five Nobel laureates, weighed more than 40 proposals to improve the world by spending a total of $75 billion over the next four years. What would do the most good most economically? Supplements of vitamin A and zinc for malnourished children. Number two? A successful outcome to the Doha Round of global flee-trade talks. Global warming mitigation? It ranked 30th, or last, right behind global warming mitigation research and development. On the benefits of freer trade, it was estimated that a successful Doha Round could generate up to $113 trillion in new wealth during the 21st century, at a cost of $420 billion or less from inefficient industries going bust. Meanwhile, providing vitamin A and zinc would help some 112 million children in sub-Saharan Africa and South Asia for merely $60 million a year. The minerals would help prevent blindness and stunted growth—increasing lifetime productivity by an estimated $1 billion. Similar if not quite so bountiful returns apply to investments in iron supplements, salt iodization and deworming, all low-cost measures that the economists in Copenhagen ranked highly.

问答题We mark the passing of 800 years, and that is indeed a remarkable span for any institution. But history is never an even-flowing stream, and the most remarkable thing about modern Cambridge has been its enormous growth over the past half century. Since I came up as an undergraduate in 1961 the student population has more than doubled. More students have meant more teachers, and, even more significantly, more scholars devoted solely to research: every category has more than doubled in numbers. This huge increase has been partly absorbed by an expansion of the colleges: they all have more students and more Fellows than they did 50 years ago; and, since 1954, no fewer than 11 of the 31 colleges are either brand new foundations, or have been conjured up as new creations from existing but quite different bodies. From being a university primarily driven by undergraduate education, Cambridge"s reputation is now overwhelmingly tied to its research achievements, which can be simply represented by the fact that more than three-quarters of its current annual income is devoted to research. This has brought not just new laboratories but new buildings to house whole faculties and departments: in the mid-20th century few faculties had a physical manifestation beyond, perhaps, a library and a couple of administrative offices. Cambridge attracts the best students and academics because they find the University and the colleges stimulating and enjoyable places in which to live and work. The students are thrown in with similarly able minds, learning as much from each other as from their teachers; the good senior academics know better than to be too hierarchical or to cut themselves off from intellectual criticism and debate. One generation dismisses another: not even Erasmus or Newton, Darwin or Keynes stand unscathed by the passage of time; nor can we be but humbled, especially in our day when so much information is so easily accessible, by the vast store of knowledge which we can approach but never really control. Our library and museum collections bring us into contact with many lives lived in the past. They serve as symbols of the continuity of learning, or the diversity of views, of an obligation to wrestle with fact and argument, to come to our own conclusions, and in turn to be accountable for our findings. The real quest is not for knowledge, but for understanding.

问答题意识到我们的文化差异可以帮助我们更有效地相互交流，了解我们不同的交流方式可以丰富我们的文化生活。不同的交流风格体现了我们深层的哲学观及世界观，这些深层的哲学观及世界观正是我们各自的文化基础。明白了这些深层哲学我们就会获得这个世界展示给我们的更加宽广的景象。 从某种意义上说，各国对多极化的认可反映了国际关系中对民主化的追求。在经济全球化的时代，一种深入的相互依赖的关系正在国与国之间形成。在联合国宪章中曾发表过的一种国与国平等的原则正深入人心，越来越多的国家已经清楚地意识到：无论大小、强弱、贫富，所有的国家都是世界大家庭中平等的一员，国际关系的民主化将成为构筑世界新秩序的共同愿望。

问答题If a heavy reliance on fossil fuels makes a country a climate ogre, then Denmark — with its thousands of wind turbines sprinkled on the coastlines and at sea — is living a happy fairy tale. Viewed from the United States or Asia, Denmark is an environmental role model. The country is "what a global warming solution looks like," wrote Frances Beinecke, the president of the Natural Resources Defense Council, in a letter to the group last autumn. About one-fifth of the country's electricity comes from wind, which wind experts say is the highest proportion of any country. But a closer look shows that Denmark is a far cry from a clean-energy paradise. The building of wind turbines has virtually ground to a halt since subsidies were cut back. Meanwhile, compared with others in the European Union, Danes remain above-average emitters of the greenhouse gas carbon dioxide. For all its wind turbines, a large proportion of the rest of Denmark's power is generated by plants that burn imported coal. The Danish experience shows how difficult it can be for countries grown rich on fossil fuels to switch to renewable energy sources like wind power. Among the hurdles are fluctuating political priorities, the high cost of putting new turbines offshore, concern about public acceptance of large wind turbines and the volatility of the wind itself. "Europe has really led the way," said Alex Klein, a senior analyst with Emerging Energy Research, a consulting firm with offices in Cambridge, Massachusetts. Some parts of western Denmark derive 100 percent of their peak needs from wind if the breeze is up. Germany and Spain generate more power in absolute terms, but in those countries wind still accounts for a far smaller proportion of the electricity generated. The average for all 27 European Union countries is 3 percent. But the Germans and the Spanish are catching up as Denmark slows down. Of the thousands of megawatts of wind power added last year around the world, only 8 megawatts were installed in Denmark. If higher subsidies had been maintained, he said, Denmark could now be generating close to one-third — rather than one-fifth — of its electricity from windmills.

问答题This week and next, governments, international agencies and nongovernmental organizations are gathering in Mexico City at the World Water Forum to discuss the legacy of global Mulhollandism in water—and to chart a new course. They could hardly have chosen a better location. Water is being pumped out of the aquifer on which Mexico City stands at twice the rate of replenishment. The result: the city is subsiding at the rate of about half a meter every decade. You can see the consequences in the cracked cathedrals, the tilting Palace of Arts and the broken water and sewerage pipes. Every region of the world has its own variant of the water crisis story. The mining of groundwaters for irrigation has lowered the water table in parts of India and Pakistan by 30 meters in the past three decades. As water goes down, the cost of pumping goes up, undermining the livelihoods of poor farmers. What is driving the global water crisis? Physical availability is part of the problem. Unlike oil or coal, water is an infinitely renewable resource, but it is available in a finite quantity. With water use increasing at twice the rate of population growth, the amount available per person is shrinking—especially in some of the poorest countries. Challenging as physical scarcity may be in some countries, the real problems in water go deeper. The 20th-century model for water management was based on a simple idea: that water is an infinitely available free resource to be exploited, dammed or diverted without reference to scarcity or sustainability. Across the world, water-based ecological systems—rivers, lakes and watersheds—have been taken beyond the frontiers of ecological sustainability by policy makers who have turned a blind eye to the consequences of over-exploitation. We need a new model of water management for the 21st century. What does that mean? For starters, we have to stop using water like there"s no tomorrow—and that means using it more efficiently at levels that do not destroy our environment. The buzz-phrase at the Mexico Water forum is "integrated water resource management." What it means is that governments need to manage the private demand of different users and manage this precious resource in the public interest.

问答题Passage 1 一个正在高速实现工业化和城市化的发展中大国，内部需求特别是消费需求持续不振，显然不是短期政策因素，而是反映了整体的经济和社会结构失衡。步入了工业化进程的廉价农村劳动力——我们称为农民工，创造了巨大的供给，却不能融入城市作为市民去消费，因此产生了巨大供需缺口。中国今后30年的发展，在很大程度上取决于我们能否在过去30年成果的基础上，抓住经济社会发展的主线，逐步废除对进城农民的身份歧视，进行制度创新，从而启动另一个30年的经济高速增长和社会平衡发展。能否做到这一点，关键在于农民工市民制的机制设计和创新，这将同30年前的家庭土地承包制度一样，启动和激发链索式的制度变迁和社会演变，成为推动下一个30年经济社会发展的引擎。

问答题The first outline of The Ascent of Man was written in July 1969 and the last foot of film was shot in December 1972. An undertaking as large as this, though wonderfully exhilarating, is not entered lightly. It demands an unflagging intellectual and physical vigour, a total immersion, which I had to be sure that I could sustain with pleasure; for instance, I had to put off researches that I had already begun; and I ought to explain what moved me to do so. There has been a deep change in the temper of science in the last 20 years: the focus of attention has shifted from the physical to the life sciences. As a result, science is drawn more and more to the study of individuality. But the interested spectator is hardly aware yet how far reaching the effect is in changing the image of man that science moulds. As a mathematician trained in physics, I too would have been unaware, had not a series of lucky chances taken me into the life sciences in middle age. I owe a debt for the good fortune that carried me into two seminal fields of science in one lifetime; and though I do not know to whom the debt is due, I conceived The Ascent of Man in gratitude to repay it. The invitation to me from the British Broadcasting Corporation was to present the development of science in a series of television programmes to match those of Lord Clark on Civilisation. Television is an admirable medium for exposition in several ways: powerful and immediate to the eye, able to take the spectator bodily into the places and processes that are described, and conversational enough to make him conscious that what he witnesses are not events but the actions of people. The last of these merits is to my mind the most cogent, and it weighed most with me in agreeing to cast a personal biography of ideas in the form of television essays. The point is that knowledge in general and science in particular does not consist of abstract but of man-made ideas, all the way from its beginnings to its modem and idiosyncratic models. Therefore the underlying concepts that unlock nature must be shown to arise early and in the simplest cultures of man from his basic and specific faculties. And the development of science which joins them in more and more complex conjunctions must be seen to be equally human: discoveries are made by men, not merely by minds, so that they are alive and charged with individuality. If television is not used to make these thoughts concrete, it is wasted.

问答题Milton Friedman, Free Markets Theorist, Dies at 94. Milton Friedman, the grandmaster of free-market economic theory in the postwar era and a prime force in the movement of nations toward less government and greater reliance on individual responsibility, died today in San Francisco, where he lived. He was 94. Conservative and liberal colleagues alike viewed Mr. Friedman, a Nobel prize laureate, as one of the 20th century"s leading economic scholars, on a par with giants like John Maynard Keynes and Paul Samuelson. Flying the flag of economic conservatism, Mr. Friedman led the postwar challenge to the hallowed theories of Lord Keynes, the British economist who maintained that governments had a duty to help capitalistic economies through periods of recession and to prevent boom times from exploding into high inflation. In Professor Friedman"s view, government had the opposite obligation: to keep its hands off the economy, to let the free market do its work. The only economic lever that Mr. Friedman would allow government to use was the one that controlled the supply of money—a monetarist view that had gone out of favor when he embraced it in the 1950s. He went on to record a signal achievement, predicting the unprecedented combination of rising unemployment and rising inflation that came to be called stagflation. His work earned him the Nobel Memorial Prize in Economic Science in 1976. Rarely, his colleagues said, did anyone have such impact on both his own profession and on government. Though he never served officially in the halls of power, he was always around them, as an adviser and theorist. "Among economic scholars, Milton Friedman had no peer," Ben S. Bernanke, the Federal Reserve chairman, said today. "The direct and indirect influences of his thinking on contemporary monetary economics would be difficult to overstate." Alan Greenspan, the former Federal Reserve chairman, said of Mr. Friedman in an interview on Tuesday. "From a longer-term point of view, it"s his academic achievements which will have lasting import. But I would not dismiss the profound impact he has already had on the American public"s view." Mr. Friedman had a gift for communicating complicated ideas in simple and lucid ways, and it served him well as the author or co-author of more than a dozen books, as a columnist for Newsweek from 1966 to 1983 and even as the star of a public television series.

问答题It's not that we are afraid of seeing him stumble, of scribbling a mustache over his career. Sure, the nice part of us wants Mike to know we appreciate him, that he still reigns, at least in our memory. The truth, though, is that we don't want him to come back because even for Michael Jordan, this would be an act of hubris so monumental as to make his trademark confidence twist into conceit. We don't want him back on the court because no one likes a show-off. The stumbling? That will be fun. But we are nice people, we Americans, with 225 years of optimism at our backs. Days ago when M.J. said he had made a decision about returning to the NBA in September, we got excited. He had said the day before, "I look forward to playing, and hopefully I can get to that point where I can make that decision. It's O.K. to have some doubt, and it's O.K. to have some nervousness." A Time/CNN poll last week has Americans, 2 to 1, saying they would like him on the court ASAR And only 21 percent thought that if he came back and just completely bombed, it would damage his legend. In fact only 28 percent think athletes should retire at their peak. Sources close to him tell Time that when Jordan first talked about a comeback with the Washington Wizards, the team Jordan co-owns and would play for, some of his trusted advisers privately tried to discourage him. "But they say if they try to stop him, it will only firm up his resolve," says an NBA source. The problem with Jordan's return is not only that he can't possibly live up to the storybook ending he gave up in 1998 — earning his sixth ring with a last-second championship-winning shot. The problem is that the motives for coming back — needing the attention, needing to play even when his 38-year-old body does not — violate the very myth of Jordan, the myth of absolute control. Babe Ruth, the 20th century's first star, was a gust of fat bravado and drunken talent, while Jordan ended the century by proving the elegance of resolve; Babe's pointing to the bleachers replaced by the charm of a backpedaling shoulder shrug. Jordan symbolized success by not sullying his brand with his politics, his opinion or superstar personality. To be a Jordan fan was to be a fan of classiness and confidence. To come back when he knows that playing for Wizards won't get him anywhere near the second round of the play-offs, when he knows that he won't be the league scoring leader, that's a loss of control. Jordan does not care what we think. Friends say that he takes articles that tell him not to come back and tacks them all on his refrigerator as inspiration. So why bother writing something telling him not to come back? He is still Michael Jordan.

问答题自20世纪90年代以来，中国政府积极探索借鉴国际反贫困经验，不断扩大与国际组织在扶贫领域的合作，并有了明显进展。 在扶贫领域，世界银行与中国的合作最早，投入规模最大。世界银行与中国目前已经开展的西南、秦巴、西部三期扶贫贷款项目，援助总规模达6.1亿美元，覆盖九个省区；91个贫困县、800多万贫困人口。其中中国西南世界银行贷款项目于1995年 7月开始在云南、贵州、广西三省(区)最贫困的35个国家级贫困县实施。项目总投资42.3亿元，其中利用世行贷款2.475亿美元，国内相应的配套资金为21.8亿元。项目建设主要包括大农业、基础设施建设、第二、三产业开发、劳务输出、教育卫生和贫困监测等方面。项目建成后将使项目区350万贫困人口稳定解决温饱问题。这一项目是中国第一个跨省区、跨行业、综合性的扶贫开发项目，也是迄今为止利用外资规模最大的扶贫项目。目前项目进展顺利，并已进入收尾阶段。

问答题移动电话正在成为2 l世纪一个主要的技术领域。在几年之内，移动电话将会发展成为多功能的通信工具，除了语音之外，还可以传输和接收视频信号、静止图像、数据和文本。个人通信的新纪元即将到来。 在一定程度上多亏了无线网络的发展，电话正在与个人电脑和电视融合起来。不久之后，配有高分辨率显示屏的轻巧手机便可以与卫星连接。人们可以随时随地通话，收发电子邮件或者参加视像电话会议。这种手机也许还会吸收电脑的许多主要功能。移动通信工具有望带来一些互联网所能提供的新服务，如股票交易、购物及预订戏票和飞机票。 电信革命已在全球范围内展开。不久之后，用一台装置就可以收到几乎任何形式的电子通信信号。最有可能的是一部三合一手机。在家里它可以用作无绳电话，在路上用作移动电话，在办公室里用作内部通话装置。有些专家甚至认为移动视像电话将超过电视，成为主要的视频信息来源。

问答题Passage 2 　　Bayer cares about the bees. 　　Or at least that’s what they tell you at the company’s Bee Care Center on its sprawling campus here between Düsseldorf and Cologne. Outside the cozy two-story building that houses the center is a whimsical yellow sculpture of a bee. Inside， the same image is fashioned into paper clips， or printed on napkins and mugs. 　　“Bayer is strictly committed to bee health，” said Gillian Mansfield， an official specializing in strategic messaging at the company’s Bayer CropScience division. She was sitting at the center’s semicircular coffee bar， which has a formidable espresso maker and， if you ask， homegrown Bayer honey. On the surrounding walls， bee fun facts are written in English， like “A bee can fly at roughly 16 miles an hour” or， it takes “nectar from some two million flowers in order to produce a pound of honey.” Next year， Bayer will open another Bee Care Center in Raleigh， N.C.， and has not ruled out more in other parts of the world. 　　There is， of course， a slight caveat to all this buzzy good will. 　　Bayer is one of the major producers of a type of pesticide that the European Union has linked to the large-scale die-offs of honey bee populations in North America and Western Europe. They are known as neonicotinoids， a relatively new nicotine-derived class of pesticide. The pesticide wasbanned this year for use on many flowering crops in Europe that attract honey bees. 　　Bayer and two competitors， Syngenta and BASF， have disagreed vociferously with the ban， and are fighting in the European courts to overturn it. 　　Hans Muilerman， a chemicals expert at Pesticide Action Network Europe， an environmental group， accused Bayer of doing “almost anything that helps their products remaining on the market. Massive lobbying， hiring P.R. firms to frame and spin， inviting commissioners to show their plants and their sustainability.” 　　“Since they learned people care about bees， they are happy to start the type of actions you mention， ‘bee care centers’ and such，” he said. 　　There is a bad guy lurking at the Bee Care Center — a killer of bees， if you will. It’s just not a pesticide. 　　Bayer’s culprit in the mysterious mass deaths of bees can be found around the corner from the coffee bar. Looming next to another sculpture of a bee is a sculpture of a parasite known as a varroa mite， which resembles a gargantuan cooked crab with spiky hair. 　　The varroa， sometimes called the vampire mite， appears to be chasing the bee next to it， which already has a smaller mite stuck to it. And in case the message was not clear， images of the mites， which are actually quite small， flash on a screen at the center. 　　While others point at pesticides， Bayer has funded research that blames mites for the bee die-off. And the center combines resources from two of the company’s divisions， Bayer CropScience and Bayer Animal Health， to further study the mite menace. 　　“The varroa is the biggest threat we have” said Manuel Tritschler， 28， a third-generation beekeeper who works for Bayer. “It’s very easy see to them， the mites， on the bees，” he said， holding a test tube with dead mites suspended in liquid. “They suck the bee blood， from the adults and from the larvae， and in this way they transport a lot of different pathogens， virus， bacteria， fungus to the bees，” he said. 　　Conveniently， Bayer markets products to kill the mites too — one is called CheckMite — and Mr. Tritschler’s work at the center included helping design a “gate” to affix to hives that coats bees with such chemical compounds. 　　There is no disputing that varroa mites are a problem， but Mr. Muilerman said they could not be seen as the only threat. 　　The varroa mite “cannot explain the massive die-off on its own，” he said. “We think the bee die-off is a result of exposure to multiple stressors.”

问答题When foreigners are sometimes asked what seems most strange about American society, somewhere on the top of the list will be the fact the average citizen is allowed to possess guns. Although it is true that many people carry guns legally in the United States, it is also known that many who possess guns carry illegally. Others, who don't have guns, feel that guns can be acquired quite easily. A recent survey indicated that many high school students, especially in the inner cities, can acquire gun with little difficulty. Although most people would never want to own a gun, others have taken up hunting as a sport and enjoy hunting wild game in season. Hunting for deer and duck in fall and winter is very much a part of the American culture. Also, some farmers in rural areas who raise cattle and sheep feel they need to protect their animals against wolves that attack their herds and flocks at night. To defend and support their fights to possess firearms the National Rifle Association (NRA) was founded in 1871. The main importance of this organization has been its efforts to prevent strict gun control legislation. The NRA has great political support in small towns and rural areas, especially in the West and the South, where hunting is especially popular. Those who favor the fight to possess guns insist that the Constitution provides the right of people "to keep and bear arms". They believe that gun control laws will not solve the problem of crime and violence in America. Recent events in America, however, have shown that the question of gun possession is now out of control and strong voices have called for immediate action to be taken. In seemingly peaceful schools students have gone into classrooms and opened fire upon their classmates. America has been shocked by such incidents which seem to occur with greater frequency. The periodic deaths of innocent citizens and even foreign visitors from guns have forced legislators to pass laws to stop these senseless killings. The day may not be far off when America will be transformed from a gun culture to one which controls their use and possession.

问答题{{B}}{{U}}What Is the Force of Gravity?{{/U}}{{/B}} {{U}}If you throw a ball up, it will come down again. What makes it come down? The ball comes down because it is pulled or attracted towards the Earth. The Earth exerts a force of attraction on all objects. Objects that are nearer to the Earth are attracted to it with a greater force than those that are further away. This force of attraction is known as the force of gravity. The gravitational force acting on an object at the Earth's surface is called the weight of the object.{{/U}} {{U}}All the heavenly bodies in space like the moon, the planets and the stars also exert an attractive force on objects. The bigger and heavier a body is, the greater is its force of gravity. Thus, since the moon is a smaller body than the Earth, the force it exerts on an object at its surface is less than that exerted by the Earth on the same object on the Earth's surface. In fact, the moon's gravitational force is only one-sixth that of the Earth. This means that an object weighing 120 kilograms on Earth will only weigh 20 kilograms on the moon. Therefore on the moon you could lift weights which are six times heavier than the heaviest weight that you can lift on Earth.{{/U}} {{U}}The Earth's gravitational force or pull keeps us and everything else on Earth from floating away to space.

Scientists have been working on this for a long time. It is only recently that they have been able to build machines powerful enough to get out of the Earth's gravitational pull. Such machines are called space rockets. Their great speed and power help them to escape from the Earth's gravitational pull and go into space.{{/U}} {{B}}{{U}}Rockets{{/U}}{{/B}} {{U}}The powerful space rocket works along the same lines as a simple firework rocket. The firework rocket has a cylindrical body and a conical head. The body is packed with gunpowder which is the fuel. It is a mixture of chemicals that will bum rapidly to form hot gases.{{/U}} {{U}}At the base or foot of the rocket there is an opening or nozzle. A fuse hangs out like a tail from the nozzle. A long stick attached along the body serves to direct the rocket before the fuse is lighted.{{/U}} {{U}}When the gunpowder bums, hot gases or exhaust gases rush out of the nozzle. The hot gases continue to rush out as long as the gunpowder bums. When these gases shoot downwards through the nozzle the rocket is pushed upwards. This is called jet propulsion. The simple experiment, shown in the picture, will help you to understand jet propulsion.{{/U}}

问答题Offshore supply vessels resembling large, floating flat-backed trucks fill Victoria Dock, unable to find charters in a sign of the downturn in Britain"s oil industry. With UK North Sea oil and gas production 44 percent below its peak, self-styled oil capital of Europe Aberdeen fears the slowdown is not simply cyclical. The oil industry that at one stage sparked talk of Scotland as "the Kuwait of the West" has already outlived most predictions. Tourism, life sciences, and the export of oil services around the world are among Aberdeen"s targeted substitutes for North sea oil and gas—but for many the biggest prize would be to use its offshore oil expertise to build a renewable energy industry as big as oil. The city aims to use its experience to become a leader in offshore wind, tidal power and carbon dioxide capture and storage. Alex Salmond, head of the devolved Scottish government, told a conference in Aberdeen last month the market for wind power could be worth 130 billion pounds, while Scotland could be the "Saudi Arabia of tidal power." "We"re seeing the emergence of an offshore energy market that is comparable in scale to the market we"ve seen in offshore oil and gas in the last 40 years," he said. Another area of focus, tourism, has previously been hindered by the presence of oil. Eager to put Aberdeen on the international tourist map, local business has strongly backed a plan by U.S. real estate tycoon Donald Trump for a luxury housing and golf project 12km (8 miles) north of the city, even though it means building on a nature reserve. The city also hopes to reorientate its vibrant oil services industry toward emerging offshore oil centers such as Brazil. "Just because the production in the North Sea starts to decline doesn"t mean that Aberdeen as a global center also declines," said Robert Collier, Chamber of Commerce Chief Executive. "That expertise can still stay here and be exported around the world."
