单选题 Etymology, the study of words and word roots, may sound like the kind of thing done by boring librarians in small, dusty rooms. Yet etymologists actually have a uniquely interesting job. They are in many ways just like archaeologists digging up the physical history of people and events. The special aspect of etymology is that it digs up history, so to speak, through the words and phrases that are left behind. The English language, in particular, is a great arena in which to explore history through words. As a language, English has an extraordinary number of words. This is in part due to its ability to adapt foreign words so readily. For example, "English" words such as kindergarten (from Germany), croissant (from French), and cheetah(from Hindi) have become part of the language with little or no change from their original sounds and spellings. So English-language etymologists have a vast world of words to explore. Another enjoyable element of etymology for most word experts is solving word mysteries. No, etymologists do not go around solving murders, cloaked in intrigue like the great fictional detective Sherlock Holmes. What these word experts solve are mysteries surrounding the origins of some of our most common words. One of the biggest questions English language experts have pursued is how English came to have the phrase OK. Though it is one of the most commonly used slang expressions, its exact beginning is a puzzle even to this day. Even its spelling is not entirely consistent—unless you spell it okay, it's hard even to call it a word. Etymologists have been able to narrow OK's origin down to a likely, although not certain, source. It became widely used around the time of Matin Van Buren's run for president in 1840. His nickname was Old Kinderhook. What troubles word experts about this explanation is that the phrase appeared in some newspapers before Van Buren became well-known. As a result, it's unlikely that Van Buren could be called its primary source. Like bloodhounds following a faint scent, etymologists will doubtless keep searching for the initial source. However, it is clear that OK's popularity and fame have exceeded those of the American president to whom it has been most clearly linked.

单选题 Some economists believe that the United States can be utilized as a "land bridge" for the shipment of containerized cargo between Europe and the Far East. Under the land- bridge concept, containerized freight traveling between Europe Line and the Far East would be shipped by ocean carrier to the United States East Coast, unloaded and placed on special railway flatc, rs, and shipped via railroad to a West Coast port. At this port, the containers would then be loaded on ships bound to a Far East port of entry. This procedure would be reversed for material traveling in the opposite direction. Thus, a land transportation system would be substituted for marine transportation during part of the movement of goods between Europe and the Far East. If a land-bridge system of shipment were deemed feasible and competitive with alternative methods, it would open a completely new market for both United States steamship lines and railroads. At present, foreign lines carry all Far East-Europe freight. American carriers get none of this trade, and the all-water route excludes the railroads. The system established by a land bridge could also serve to handle goods now being shipped between the United States West Coast and Europe, or goods shipped between the Far East and the United States Gulf and East Coast. Currently, there are 20 foreign lines carrying West Coast freight to Europe via the Panama Canal, but not one United States line. Thus, in addition to the land bridge getting this new business for the railroads, it also gives the United States East Coast ships an opportunity to compete for this trade. While this method of shipment will probably not add to the labor requirements at East and West Coast piers, it does have the potential of absorbing some of the jobs that the containerization of current cargo has eliminated or could eliminate. Thus, the possibility of creating new jobs for longshoremen is not an expected benefit of such a system, but it will most certainly create other labor requirements. The land-bridge concept has the potential of offering new job openings for United States railway workers and seamen. In addition, there would be expansion of labor requirements for people in the shipbuilding and container manufacturing business. By making United States rail transportation an export service, the land-bridge system would have a favorable effect on our balance of payments. Such a system also has the potential of relieving the United States government of part of the burden it now bears in the form of subsidies to the shipping industry. The federal government subsidizes the construction and operation of scheduled vessels. Some 52 percent of the income from their operation comes from the government in that these ships are used for all our military and other government-related export shipments. The land-bridge requirement for scheduled sailings could effect a shift from the use of these scheduled lines for shipment of government goods to commercial cargo of the land bridge. This would then open some of the lucrative government business to the unscheduled, unsubsidized lines.

单选题Even plants can run a fever, especially when they're under attack by insects or disease. But unlike humans, plants can have their temperature taken from 3,000 feet away-- straight up. A decade ago, adapting the infrared scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide (杀虫剂) spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest (害虫) problems. Even better, Paley's Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running "fevers". Farmers could then spot-spray, using 40 to 70 percent less pesticide than they otherwise would. The bad news is that Paley's company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of agricultural land in the United States," says George Oerther of Texas A&M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.

单选题On an average of six times a day, a doctor in Holland practices "active" euthanasia: intentionally administering a lethal (致死的) drug to a terminally ill patient who has asked to be relieved of suffering. Twenty times a day, life-prolonging treatment is withheld or withdrawn when there is no hope that it can effect an ultimate cure. "Active" euthanasia remains a crime on the Dutch statute books, punishable by 12 years in prison. But a series of court cases over the past 15 years has made it clear that a competent physician who carries it out will not be prosecuted. Euthanasia, often called "mercy killing" is a crime everywhere in Western Europe. But more and more doctors and nurses readily admit to practicing it, most often in the "passive" form of withholding or withdrawing treatment. The long simmering euthanasia issue has lately boiled over into a, sometimes, fierce public debate, with both sides claiming the mantle of ultimate righteousness. Those opposed to the practice see themselves upholding sacred principles of respect for life, while those in favor raise the banner of humane treatment. After years on the defensive, the advocates now seem to be gaining ground. Recent polls in Britain show that 72 percent of British subjects favor euthanasia in some circumstances. An astonishing 76 percent of respondents to a poll taken last year in France said they would like the law changed to decriminalize mercy killings. Euthanasia has been a topic of controversy in Europe since at least 1936, when a bill was introduced in the House of Lords that would have legalized mercy killing under very tightly supervised conditions. That bill failed, as have three others introduced in the House of Lords since then. Reasons for the latest surge of interest in euthanasia are not hard to find. Europeans, like Americans, are now living longer. Therefore, lingering chronic diseases have replaced critical illnesses as the primary cause of death. And the euthanasists argue that every human being should have the right to "die with dignity," by which they usually mean the right to escape the horrors of a painful or degrading hospitalization (住院治疗). Most experts believe that euthanasia will continue to be practiced no matter what the law says.
