单选题{{B}}Text 3{{/B}} Tom Burke recently tried to print out a boarding pass from home before one of the frequent flights he takes. He couldn't. His name, or one similar to it, is now on one of the Transportation Security Administration's terrorist watch lists. Every day, thousands of people like Burke find themselves unable to do things like print a boarding pass and are pulled aside for extensive screening because their name, or a name that sounds like theirs, is on one of the watch lists. From the TSA's perspective, the screening is just one of the many new layers of increased security that are designed to prevent terrorist activity. The inconvenience is regrettable, but a price that society has to pay for security. And for national security reasons, the FBI and other government agencies responsible for supplying names to the lists will not disclose the criteria they use. They say that would amount to tipping their hands to the terrorists. But civil libertarians are more concerned about the long-term consequence of the current lists. On Sept. 11,2001, the no-fly list contained 16 names. Now, the combined lists are estimated to have as many as 20,000. Internal FBI memos from agents referred to the process as "really confused" and "not comprehensive and not centralized. Burke and others contend that such comments are disturbing, because it was during the first year after the attacks that the watch lists grew exponentially. "The underlying danger is not that Tom Burke can no longer get a boarding pass to get on an airline," says a lawyer. "It's that the Tom Burkes in the world may forever more be associated (with the terrorist watch list)." Burke says they do know that the lists are frequent[y updated and distributed internationally, but they don't know how the old lists are destroyed. They also hope to ensure that sometime in the future a person whose name is on the list, but is not a terrorist, does not run into further trouble if, say, law enforcement in another country that they're visiting comes across their name on one of the old lists. In addition, airlines are concerned that the lists are not updated frequently enough. "We've been encouraging the TSA to work with all of the other federal law-enforcement agencies to get a regular review of the names that they submit to TSA, because there have been reports that these agencies have said that if there was a review, many of the names could be removed," says Diana Cronin of the Air Transport Association.

单选题{{B}}Text 3{{/B}} Even their parents struggle to draw the tiniest hint of emotion or social connection from autistic(患孤独症的) children, so imagine what happens when a stranger sits with the child for hours to get through the standard IQ test. For 10 of the test's 12 sections, the child must listen and respond to spoken questions. Since for many autistics it is torture to try to engage with someone even on this impersonal level, it's no wonder so many wind up with IQ scores just above a carrot's. More precisely, fully three quarters of autistics are classified as having below-normal intelligence, with many deemed mentally retarded. Researchers have tried a different IQ test, one that requires no social interaction. As they report in the journal Psychological Science, autistic children's scores came out starkly different than on the oral, interactive IQ test — suggesting a burning intelligence inside these kids that educators are failing to uncover. For the study, children took two IQ tests. In the more widely used Wechsler, they tried to arrange and complete pictures, do simple arithmetic, demonstrate vocabulary comprehension and answer questions— almost all in response to a stranger's questions. In the Raven's Progressive Matrices test, they got brief instructions, then went off on their own to analyze three-by-three arrays of geometric designs, with one missing, and choose the design that belonged in the empty place. The disparity in scores was striking. Overall, the autistics scored around the 30th percentile on the Wechsler, which corresponds to "low average" IQ. But they averaged in the 56th percentile on the Raven's. not a single autistic child scored in the "high intelligence" range on the Wechsler; on the Raven's, one third did. Healthy children showed no such disparity. That presents a puzzle. If many autistics arc more intelligent than an IQ test shows, why haven't their parents noticed? Partly because many parents welcome a low score, which brings their child more special services from schools and public agencies. But another force is at work. "We often think of intelligence as what you can show, such as by speaking fluently," says a psychologist. "Parents as well as professionals might be biased to look at that" rather than dig for the hidden intellectual spark. The challenge is to coax that spark into the kind of intelligence that manifests itself in practice. That is something autism researchers are far from doing. Many experts dismiss autistics' exceptional reading, artistic or other abilities as side effects of abnormal brain function. They advise parents to steer their child away from what he excels at and obsesses over, and toward what he struggles with. It makes you wonder how many other children, whose intellectual potential we're too blind to see, we've also given up on.

单选题Motorola Inc., the world's second-largest mobile phone maker, will begin selling all of the technology needed to build 'a basic mobile phone to outside manufacturers, in a key change of strategy. The inventor of the cell phone, which has been troubled by missteps compounded by a recent industry slump in sales, is trying to become a neutral provider of mobile technology to rivals, with an eye toward fostering a much larger market than it could create itself. The Chicago area-based company, considered to have the widest range of technologies needed to build a phone, said it planned to make available chips, a design layout for the computer board, software, development tools and testing tools. Motorola has previously supplied mobile phone manufacturers with a couple of its chips, but this is the first time the company will offer its entire line of chips as well as a detailed blueprint. Mobile phones contain a variety of chips and components to control power, sound and amplification. Analysts said they liked the new strategy but were cautious about whether Motorola's mobile phone competitors would want to buy the technology from a rival. The company, long known for its top-notch (等级) engineering culture, is hoping to profit from its mobile phone technology now that the basic technology to build a mobile phone has largely become a commodity. Motorola said it will begin offering the technology based on the next-generation GPRS (Global Packet Radio Service) standard because most mobile phone makers already have technology in place for current digital phones. GPRS offers faster access to data through "always on" network connections, and customers are charged only for the information they retrieve, rather than the length of download. Burgess said the new business will not conflict with Motorola's own mobile phone business because the latter will remain competitive by offering advanced features and designs. Motorola's phones have been criticized as being too complicated and expensive to manufacture, but Burgess said Motorola will simplify the technology in the phones by a third. In addition to basic technology, Burgess said, Motorola would also offer additional features such as Bluetooth, a technology that allows wireless communications at a short distance, and Global Positioning System, which tracks the user's whereabouts, and MP3 audio capability.

Humans are unique in the extent to which they can reflect on themselves and others. Humans are able to {{U}}(21) {{/U}}, to think in abstract terms, to reflect on the future.

单选题Most American politicians say they support marriage, but few do much about it, except perhaps to sound off about the illusory threat to it from gays. The public are divided. Few want to go back to the attitudes or divorce laws of the 1950s. But many at both ends of the political spectrum lament the fragility of American families and would change, at least, the way the tax code penalises many couples who marry. And some politicians want the state to draw attention to benefits of marriage, as it does to the perils of smoking. George Bush is one. Since last year, his administration has been handing out grants to promote healthy marriages. This is a less preachy enterprise than you might expect. Sidonie Squier, the bureaucrat in charge, does not argue that divorce is wrong: "If you"re being abused, you should get out." Nor does she think the government should take a view on whether people should have pre-marital sex. Her budget for boosting marriage is tiny: $100m a year, or about what the Defence Department spends every two hours. Some of it funds research into what makes a relationship work well and whether outsiders can help. Most of the rest goes to groups that try to help couples get along better, some of which are religiously-inspired. The first 124 grants were disbursed only last September, so it is too early to say whether any of this will work. But certain approaches look hopeful. One is "marriage education". The army already does this. About 35,000 soldiers this year will get a 12-hour course on how to communicate better with their partners, and how to resolve disputes without throwing plates. It costs about $300 per family. Given that it costs $50,000 to recruit and train a rifleman, and that marital problems are a big reason why soldiers quit, you don"t have to save many marriages for this to be cost-effective, says Peter Frederich, the chaplain in charge. Several studies have shown that such courses do indeed help couples communicate better and quarrel less bitterly. As to whether they prevent divorce, a meta-analysis by Jason Carroll and William Doherty concluded that the jury was still out. The National Institutes of Health is paying for a five-year study of Mr Frederich"s soldiers to shed further light on the issue. At the end of the day, says Ms Squier, the government"s influence over the culture of marriage will be marginal. Messages from movies, peers and parents matter far more. But she does not see why, for example, the government"s only contact with an unmarried father should be to demand that he pay child support. By not even mentioning marriage, the state is implying that no one expects him to stick around. Is that a helpful message?
