单选题{{B}}Text 1{{/B}} In an interview last month, Frank Church, chairman of the Senate committee that is investigating the CIA, issued an oblique but impassioned warning, that the technology of eavesdropping had become so highly developed that Americans might soon be left with "no place to hide". That day may have arrived. Newsweek has learned that the country's most secret intelligence operation, the National Security Agency, already possesses the computerized equipment to monitor nearly all overseas telephone calls and most domestic and international printed messages. The agency's devices monitor thousands of telephone circuits, cable lines and the microwave transmissons that carry an increasing share of both spoken and written communications. Computers are programed to watch for "trigger" words or phrases indicating that a message might interest intelligence analysis, when the trigger is pulled, entire messages are tape-recorded or printed out. That kind of eavesdropping is, however, relatively simple compared with the breakthroughs that lie ahead in the field of snoopery. Already it is technically feasible to "bug" an electric typewriter by picking up its feeble electronic emissions from a remote location and then translating them into words. And some scientists believe that it may be possible in the future for remote electronic equipment to intercept and "read" human brain waves. Where such capabilities exist, so too does the potential for abuse. It is the old story of technology rushing forward with some new wonder, before the man who supposedly control the machines have figure out how to prevent the machines from controlling them.

单选题In which of the following does the author present the passage?

单选题Advertising sells its products by offering seductive promises of youth, beauty, health, money, ease, romance, better lifestyle, even time. There's no logical connection between a car and a cougar, but the image is powerful and presented with sophistication. We buy it and we may well buy the product. When it comes to advertising, let the buyer beware. There are several less-than-candid techniques which advertisers use to get our attention. A product may be filmed or photographed in such a way to make it appear bigger, better, or more luscious. A product may be presented as being "unique", "one-of-a-kind", or "supreme", when in fact it's identical to other products on the market. A product may claim to be "new" or "improved" when only an insignificant change has been made. Finally, an advertiser may offer distorted truths or even tell outright lies. It takes a while for the government or the competition to catch up with false claims in advertising. Meanwhile, the public has been led to believe that a mouth wash can cure the common cold, or that bee pollen retards aging in human skin. The consumer's best defense is awareness. He can listen to, but not learn, the emotional message broadcast by the ad. He can distinguish between what the ad pretends to offer and what it is really selling. A face cream, for example, can only do so much. It can reduce dryness and provide temporary smoothness and moisture to the skin. But it is made in a factory, not in a magician's study. It cannot turn back the clock.

单选题It is hard to box against a southpaw, as Apollo Creed found out when he fought Rocky Balboa in the first of an interminable series of movies. While "Rocky" is fiction, the strategic advantage of being left-handed in a fight is very real, simply because most right-handed people have little experience of fighting left-handers, but not vice versa. And the same competitive advantage is enjoyed by left-handers in other sports, such as tennis and cricket. The orthodox view of human handedness is that it is connected to the bilateral specialization of the brain that has concentrated language-processing functions on the left side of that organ. Because, long ago in the evolutionary past, an ancestor of humans (and all other vertebrate animals ) underwent a contortion that twisted its head around 180° relative to its body, the left side of the brain controls the right side of the body, and vice versa. In humans, the left brain (and thus the right body ) is usually dominant. And on average, left-handers are smaller and lighter than right-handers. That should put them at an evolutionary disadvantage. Sporting advantage notwithstanding, therefore, the existence of left-handedness poses a problem for biologists. But Charlotte Faurie and Michel Raymond, of the University of Montpellier Ⅱ, in France, think they know the answer. As they report in the Proceedings of the Royal Society, there is a clue in the advantage seen in boxing. As any schoolboy could tell you, winning fights enhances your status. If, in prehistory, this translated into increased reproductive success, it might have been enough to maintain a certain proportion of left-handers in the population, by balancing the costs of being left- handed with the advantages gained in fighting. If that is true, then there will be a higher proportion of left-handers in societies with higher levels of violence, since the advantages of being left-handed will be enhanced in such societies. Dr Faurie and Dr Raymond set out to test this hypothesis. Fighting in modern societies often involves the use of technology, notably firearms, that is unlikely to give any advantage to left-handers. So Dr Faurie and Dr Raymond decided to confine their investigation to the proportion of left-handers and the level of violence (by number of homicides) in traditional societies. By trawling the literature, checking with police departments, and even going out into the field and asking people, the two researchers found that the proportion of left-handers in a traditional society is, indeed, correlated with its homicide rate. One of the highest proportions of left-handers, for example, was found among the Yanomamo of South America. Raiding and warfare are central to Yanomamo culture. The murder rate is 4 per 1000 inhabitants per year (compared with, for example, 0.068 in New York). And, according to Dr Faurie and Dr Raymond, 22.6% of Yanomamo are left-handed. In contrast, Dioula-speaking people of Burkina Faso in West Africa are virtual pacifists. There are only 0.013 murders per 1000 inhabitants among them and only 3.4% of the population is left- handed. While there is no suggestion that left-handed people are more violent than the right- handed, it looks as though they are more successfully violent. Perhaps that helps to explain the double meaning of the word "sinister".

单选题{{B}}Part A{{/B}}{{B}}Text 1{{/B}} Even to his contemporaries, Rochester was a legendary figure One of the youngest and most handsome courtiers of the restored Charles Ⅱ. he was the favorite of a king whose wit, lasciviousness and serious intellectual interests he shared. He was banished from court several times, but Charles's pleasure in his conversation always resulted in his recall. His authentic adventures included the attempted abduction of an heiress (whom he later married), smashing a phallic-shaped sundial in the royal gardens during a drunken celebrity, and a violent quarrel with the watch at Epsom in which one of his companions was killed. Quite apart from his reputation as a poet. he was feted in the writings of his friends, notably in Sir George Etherege's comedy, "The Man of Mode". Just before he died in 1680. at the age of 33. destroyed by alcoholism and syphilis. Rochester's legend took a surprising turn. After a series of conversations with an Anglican rationalist divine. Gilbert Burner, the skeptical libertine made a death- bed conversion which was celebrated in the devotional literature of the succeeding century. Charming as it is. the Rochester legend has always been a distraction It has resulted in many apocryphal stories and uncertain attributions, and it can still divert attention from the poetry. It is Rochester's achievement as a poet which commands our interest and makes him something more than a luridly colorful period, figure. For all the brevity of his career, Rochester is a crucial figure in the development of English verse satire and file Horatian epistle, a student of his elder French contemporary Boileau. and an important exemplar for later poets as different as Alexander Pope and Anne Finch, Countess of Winchilsea. Cephas Goldsworthy's "The Satyr" gives us the legend. Although there are no footnotes to sources, the book shows some acquaintance with modem Rochester scholarship and its rejection of spurious verse from his canon—but only intermittently. Anecdotes concerning Rochester and his crony George Villiers, Duke of Buckingham. are retailed without any indication that they have, in fact. been discredited; poems no longer attributed to Rochester are cited as if they were authentic. Mr. Goldsworthy quotes liberally from the poetry, but repeatedly reads it as straightforward autobiography. For example, we are told that "My dear mistress has a heart" is addressed to. Elizabeth Barry, an actress, which is incautious given the uncertain dating of this song, and indeed of most of Rochester's poems. More generally, while of course some of the satires include references to actual persons, as often as not in 17th-century love poetry the emotion is genuine but the addressee is fictitious. A less simplistic way to relate Rochester's poetry to his life would be to read the former as an exploiation of what it means to live according to libertine values. In his best satires and even some of the lyrics he articulated an anti-rational .{{U}}nihilistic{{/U}} vision scarcely found elsewhere in English verse. Such a task belongs to a critical biography. There is no mistaking Mr. Goldsworthy's enthusiasm for his subject, but his book is essentially biography as entertainment.

单选题Electronics are being recycled in record numbers as more states require it and more companies collect and even pay for discarded items, but the gains come with controversy. Some environmentalists complain that recycling is not keeping pace with electronics sales. Some say e-waste is being dumped in developing countries, where toxic materials such as lead and mercury can leach from landfills into groundwater. "It is a success story, but we'd like to see it get more successful" to keep up with the electronics boom, says Janette Petersen of the Environmental Protection Agency (EPA). The amount of recycled items more than doubled from 1999 to 2007, the most recent year for which the EPA has figures. But as a percentage of all electronics, it increased less, from 15% to 18%. "The demand for electronics recycling has been growing," partly because of the switch last year to digital TV, says Jennifer Berry of Earth911. corn, a private group that keeps a database of recyclers. Last year, she says 31% of inquiries involved electronics, primarily TVs, batteries and computers. Public and private efforts are expanding. Vermont became the 21st state last month to enact a law that requires e-waste recycling. Twenty-six companies--including Dell, Hewlett Packard, ATT and Verizon--have partnered with the EPA on the Plug-In to eCycling program to promote electronics recycling since its launch in 2003. Companies such as Gazelle. corn pay for used gadgets such as iPods, which they resell or recycle. Best Buy and other stores are collecting more e-waste. Target announced last month that it put bins in every store to accept cellphones, MP3 players and ink cartridges. Jim Puckett of Basel Action Network, a Seattle-based non-profit organization that aims to stop toxic exports, worries that some American companies dump e-waste in Africa to save money. "People are trying to look green, but they're not telling you where it (waste) is going," he says. "You can't turn over your TV to just any recycler. " He says it's better to store an old TV than give it to a recycler that may export it to poor countries. The Basel Action Network announced its e-Stewards program last month to ensure safe handling of electronics by using only recyclers certified by accredited organizations. It now lists 45 recyclers in 80 locations. Samsung and other companies have signed on. Environmental groups, including the Sierra Club, back it.
