单选题{{B}}Text 2{{/B}} This book is written expressly for students in an attempt to present the material that is most useful and interesting to them. Previous courses in chemistry are not necessary for the understanding of the material, although those students who have had high school chemistry will find that a review of the inorganic section will better enable them to master the organic and biochemistry sections that follow. The author has felt that in the past there was an improper selection of material from inorganic, organic, and biochemistry in the majority of the textbooks of chemistry for nurse. The tendency has been to develop the inorganic chemistry to such an extent that organic and biochemistry is covered too briefly. The recent advances in biochemistry and their widespread application to the practice of medicine and nursing have considerably altered the situation. Not only is biochemistry more closely allied to the practical chemistry of medicine and nursing but also it is of more interest to the student. In the author's experience the response to biochemistry has always been more favorable than to the other sections. Within the brief period allotted to chemistry, therefore, the sections on inorganic, organic, and biochemistry should be so arranged that a good share of the time is spent in the study of biochemistry. This book presents mainly those fundamentals of inorganic and organic chemistry that are necessary for the understanding of the section on biochemistry. The fundamental points suggested in the Curriculum Guide are included in the book, with some additions in the biochemistry section. The author feels that a study of urine, vitamins, nutrition, and hormones is so obviously a part of biochemistry that at least the fundamentals should be included in this course. The book has been planned in such a way that it may be adapted to various courses in chemistry. The material suggested by the Curriculum Guide is covered in the first nineteen chapters and may be used in accelerated courses or where minimum time is allotted to chemistry. When the time allotted to the course is sixty to ninety hours, the entire contents of the book may be used to advantage. While the book has been written especially to fit the needs of Schools of Nursing, it could readily be applied in instances where students are required to take but one course in chemistry. The apathetic attitude of nonprofessional students toward a course in inorganic chemistry may well be overcome by the proper presentation of material selected from inorganic, organic, and biochemistry.

单选题The term "disruptive technology" is popular, but is widely misused. It refers not simply to a clever new technology, hut to one that undermines an existing technology--and which therefore makes life very difficult for the many businesses which depend on the existing way of doing things. Twenty years ago, the personal computer was a classic example. It swept aside an older mainframe-based style of computing, and eventually brought IBM, one of the world's mightiest firms at the time, to its knees. This week has been a coming-out party of sorts for another disruptive technology, "voice over internet protocol" (VOIP), which promises to be even more disruptive, and of even greater benefit to consumers, than personal computers. VOIP's leading proponent is Skype, a small firm whose software allows people to make free calls to other Skype users over the internet, and very cheap calls to traditional telephones--all of which spells trouble for incumbent telecoms operators. On September 12th, eBay, the leading online auction house, announced that it was buying Skype for ＄2.6 billion, plus an additional ＄1.5 billion if Skype hits certain performance targets in coming years. This seems a vast sum to pay for a company that has only ＄60m in revenues and has yet to turn a profit. Yet eBay was not the only company interested in buying Skype. Microsoft, Yahoo!, News Corporation and Google were all said to have also considered the idea. Perhaps eBay, rather like some over-excited bidder in one of its own auctions, has paid too much. The company says it plans to use Skype's technology to make it easier for buyers and sellers to communicate, and to offer new "click to call" advertisements, but many analysts are sceptical that eBay is the best owner of Skype. Whatever the merits of the deal, however, the fuss over Skype in recent weeks has highlighted the significance of VOIP, and the enormous threat it poses to incumbent telecoms operators. For the rise of Skype and other VOIP services means nothing less than the death of the traditional telephone business, established over a century ago. Skype is merely the most visible manifestation of a dramatic shift in the telecoms industry, as voice Galling becomes just another data service delivered via high-speed internet connections. Skype, which has over 54m users, has received the most attention, but other firms routing calls partially or entirely over the internet have also signed up millions of customers.

单选题{{B}}Text 4{{/B}} As thick-skinned elected officials go, FIFA President Joseph S. Blatter is right up there with Bill Clinton. The chief of the Zurich based group that oversees World Cup soccer hasn't been accused of groping any interns, but that's about all he hasn't been accused of. Vote buying, mismanagement, cronyism—and that's just for starters. Yet the 66-year-old Swiss shows no sign of abandoning his campaign for a second four-year term. Blatter, a geek of dispensing FIFA'S hundreds of million in annual revenue to inspire loyalty, even stands a good chance of reelection. At least he did. Since mid-March, he has seen a credible challenger emerge in Issa Hayatou, president of the African Football Confederation. Hayatou, a 55-year-old from Cameroon, leads a group of FIFA reformers that also includes FIFA Vice-President Lennart Johansson, a Swede who lost the presidential election to Blatter in 1998. These contenders' mission: to end what they call the culture of secrecy and lack of accountability that threatens FIFA with financial disaster. Representatives of the world's 204 national soccer associations meet in Seoul on May 29, and the rebels are given a chance of unseating Blatter. But even they concede that the FIFA honcho won't be easy to dislodge. Blatter's staying power seems incredible, given the array of misdeeds attributed to him and his circle. However, there are signs that FIFA'S troubles are bigger than Blatter is saying. The insurgents have already won one victory: They persuaded the rest of the executive board to order an audit of FIFA finances. But Blatter who claims, through a spokesman, that the accusations are a smear campaign-should not be underestimated. At least publicly, sponsors and member associations remain remarkably silent with the controversy. For example, there is no outward sign of outrage from German sports equipment maker Adidas-Salomon, which is spending much of its ＄625 million marketing budget on the World Cup. "We don't expect current developments within FIFA to have a negative impact on our expectations" for the World Cup, says Michael Riehl, Adidas head of global sports marketing. The conventional wisdom is that fans don't care about FIFA politics. Says Bernd Schiphorst, president of Hertha BSC Berlin, a top ranked German team: "I've no fear that all these discussions are going to touch the event." Still, the Olympic bribery scandals and the {{U}}doping affair in the Tour{{/U}} de France show that sleazy dealings can stain the most venerable athletic spectacle. "For the Good of the Game" is FIFA'S official motto. The next few months should show whether it rings true.

单选题The Scottish countryside will soon be home to creatures which is strange to Britain. This spring, 17 beavers (海狸) will be released into a remote area of rivers and forests. Hunted to extinction throughout Europe, beavers haven't roamed Britain's wilderness for almost 500 years. Ecologists would like to invite back other long-lost species to help restore the natural balance. To save the country's plants from deer, which have doubled to 2 million since the start of this decade, an Oxford University biologist late last year called for reintroducing the lynx (猞猁)—a wildcat that died out in Britain 1,300 years ago. Nature has long been a popular cause in Europe. British people love their countryside of fences and fields, the French their vineyards (葡萄园) and the Germans their hiking forests. But in recent years conservationists have set their sights on the more distant past, when Europe's forests and meadows were full of elephants, hippo-potamuses (河马), rhinoceroses(犀牛) and big cats. Some ambitious conservationists are now advocating a return to norms of wilderness that date back to 11,000 years ago when the biggest mammals were at the top of the food chain. Nobody is advocating allowing elephants and lions to run crazily in this densely populated region. But wilding supporters would give free control to a long list of lesser mammals, including the beaver and the lynx, which some people fear could be destructive. Some landowners withdraw at the thought of beavers cutting down trees with their teeth and flooding their property; the Scottish Parliament rejected several earlier efforts to reintroduce the mammal. Proposals to set loose wolves and bears in Britain have also encountered resistance. Although rhinos and hippos thrived in Europe thousands of years ago, no one is sure what effect they would have on ecosystems now. "The idea of bringing back big mammals is interesting, but when you get down to the nuts and bolts, there's a lot of questions," say some biologists. For example, elephants could destroy what little forest and grassland Europe has left. The beavers of Tierra del Fuego provide a cautionary tale. When a failed commercial fur farm released its few remaining beavers into the wild 60 years ago, the population exploded, and they are still revenging the local people. Is this Britain's future? Supporters say no, the beaver will fit right in. Destroying nature is not a job for the mild.

单选题No blueprint exists for transforming an economy from one with a great deal of government control to one based almost solely on free market principles. Yet the experience of the United Kingdom since 1979 clearly shows one approach that works: privatization, in which under-performing state-owned are sold to private companies. By 1979, the total amount of debt, liabilities, and losses for state-controlled enterprises in the UK topped 3 billion annually. By selling off many of these companies, particularly those in the depressed industrial sector, the government decreased its debt burden and ceased pumping public funds into money losing enterprises. According to government spokesperson Alistair McBride, "Far from past practice of throwing good money after bad, the Queen's government this year expects to take in 34 billion from the proceeds of the sale." That, say some analysts, may only be the beginning. Privatization has not only been credited with rescuing whole industries but the nation's economy to boot. Due to increased tax revenues from the newly privatized companies along with a rebound in the overall economy, economic forecasters predict that Britain will be able to repay nearly 12.5% of the net national debt within two years. That is good news indeed for the economy as a whole at a time when many sectors are desperate for any ray of sunshine. British Airways this week announced a 20% jump in overall ticket sales and profits over this quarter a year ago. British Gas announced its first profitable quarter in nine years. At Associated British Ports, a new labor contract was finalized, the first union contract signed at the port without a work stoppage in twelve years. Closer to home for most Britons, the nation's phone service, British Telecom, no longer puts new subscribers on a waiting list. Prior to privatization, new customers would sometimes have to wait months before phone service could be installed in their home. Now, according to a company press release, British Telecom is promising 24-hour turnaround for all new customers. Part of this improved productivity has to do with new efforts to allow employees to hold a stake in the company's future. Companies now give their employees stock options that allow employees to share in the company's success (and profits). The response has been enthusiastic to say the least. At British Aerospace; 89% of those eligible to buy company shares did so. At British Telecom nearly 92% of eligible employees took part. Finally, at Associated British Ports, long synonymous with union disagreements, walkouts, and labor strife, almost 90% of employees now can call themselves owners of the company. "When people have a personal stake in something," said Henry Dundee of Associated British Ports, "they think about it, they care about, they work to make it prosper." At the National Freight Consortium, itself no stranger to labor problems, the new employee-owners actually voted down an employee pay-increase and, pressured union representatives to relax demands for increased wages and expanded benefits. "Privatization was only the start," says one market analyst, "what we may have here is a new industrial revolution./

单选题When it comes to the slowing economy, Ellen Spero isn"t biting her nails just yet. But the 47-year-old manicurist isn"t cutting, filling or polishing as nails as she"d like to, either. Most of her clients spend $12 to $50 weekly, but last month two longtime customers suddenly stopped showing up. Spero blames the softening economy. "I"m a good economic indicator," she says, "I provide a service that people can do without when they"re concerned about saving some dollars." So Spero is downscaling, shopping at middle-brow Dillard"s department store near her suburban Cleveland home, instead of Neiman Marcus, "I don"t know it other clients are going to abandon me, too." She says. Even before Alan Greenspan"s admission that America"s red-hot economy is cooling, lots of working folks had already seen signs of the slowdown themselves. From car dealer-ships to Gap outlets, sales have been lagging for months as shoppers temper their spending. For retailers, who last year took in 24 percent of their revenue between Thanksgiving and Christmas, the cautious approach is coming at a crucial time. Already, experts say, holiday sales are off 7 percent from last year"s pace. But don"t sound any alarms just yet. Consumers seem only mildly concerned, not panicked, and many say they remain optimistic about the economy"s long-term prospects, even as they do some modest belt-tightening. Consumers say they"re not in despair because, despite the dreadful headlines, their own fortunes still feel pretty good. Home prices are holding steady in most regions. In Manhattan, "there"s a new gold rush happening in the $4 million to $10 million range, predominantly fed by Wall Street bonuses." Says broker Barbara Corcoran. In San Francisco, prices are still rising even as frenzied overbidding quiets. "Instead of 20 to 30 offers, now maybe you only get two or three," says John Tealdi, a Bay Area real-estate broker. And most folks still feel pretty comfortable about their ability to find and keep a job. Many folks see silver linings to this slow-down. Potential home buyers would cheer for lower interest rates. Employers wouldn"t mind a little fewer buddles in the job market. Many consumers seem to have been influenced by stock-market swings, which investors now view as a necessary ingredient to a sustained boom. Diners might see an upside, too. Getting a table at Manhattan"s hot new Alain Ducasse restaurant used to be impossible. Not anymore. For that, Greenspan & Co. may still be worth toasting.
