单选题The standardized educational or psychological tests that are widely used to aid in selecting, classifying, assigning, or promoting students, employees, and military personnel have been the target of recent attacks in books, magazines, the daily press, and even in Congress. The target is wrong, for in attacking the tests, critics divert attention from the fault that lies with ill-informed or incompetent users. The tests themselves are merely tools, with characteristics that can be measured with reasonable precision under specified condition. Whether the results will be valuable, meaningless, or even misleading depends partly upon the tool itself hut largely upon the user. All informed predictions of future performance are based upon some knowledge of relevant past performance. How well the predictions will be validated by later performance depends upon the amount, reliability, and appropriateness of the information used and on the skill and wisdom with which it is interpreted. Anyone who keeps careful score knows that the information available is always incomplete and that the predictions are always subject to error. Standardized tests should be considered in this context. They provide a quick, objective method of getting some kinds of information about what a person has learned, the skills he has developed, or the kind of person he is. The information so obtained has, qualitatively, the same advantages and short-comings as other kinds of information. Whether to use tests, other kinds of information, or both in a particular situation depends, therefore, upon the empirical evidence concerning comparative validity, and upon such factors as cost and availability. In general, the tests work most effectively when the traits or qualities to he measured can be most precisely defined (for example, ability to do well in a particular course or training program) and least effectively when what is to be measured or predicted cannot be well defined (for example, personality or creativity). Properly used, they provide a rapid means of getting comparable information about many people. Sometimes they identify students whose high potential has not been previously recognized.

单选题{{B}}Passage Two{{/B}} The Pakistani president, Gen. Pervez Musharraf, announced here today that a delegation of Pakistani officials would fly to the Taliban's headquarters in the southern Afghan city of Kandahar Monday to renew demands that the militia surrender Saudi fugitive Osama bin Laden. U. S. officials have named bin Laden, who has been given shelter by the Taliban rulers in Afghanistan, as the prime suspect in Tuesday's terrorist attacks in Washington and New York. "We are aware of the gravity of the situation and know that in the lives of, nations, such situations do arise that require making important decisions," Musharraf said at a meeting with Pakistani newspaper editors. The Taliban's leader, Mohammad Omar, has refused to give up bin Laden, claiming he is not responsible for the U. S. attacks. "The Pakistan government is leaning on the Taliban government to hand over Osama to save this entire region from catastrophe," said Najam Sethi, editor of the weekly newspaper Friday Times, who participated in the meeting with Musharraf. "I am not sure whether there is much chance of that happening, but the pressure is on from the Pakistan government." Pakistan has been a key supporter of the Taliban, which controls more than 90 percent of Afghanistan and has enforced a strict interpretation of Islamic law in the country. Omar, the Taliban leader, today convened an emergency meeting of clerics (圣职人员) in the Afghan capital, Kabul. "As regards the possible attack by America on the sacred soil of Afghanistan, veteran honorable clerics should come to Kabul for a sharia decision," Omar said in a statement broadcast on the Taliban's Radio Shariat today. Sharia is Islamic law. Omar, who reportedly left Ms Kandahar headquarters several days ago in anticipation of a U. S. attack, asked Afghans to pray and read the Koran to meet what he called a "test", according to the statement. He indicated he would not attend the meeting of clerics, though he reportedly met with a small group of senior clerics today. The Pakistan-based Afghan Islamic Press reported today it had received a statement from Bin Laden, dispathed by an aide from an undisclosed location in Afghanistan, in which he denied involvement in last week's attacks on the World Trade Center and the Pentagon. "I am residing in Afghanistan," the statement said. "I have taken an oath of allegiance to Omar, which does not allow me to do such things from Afghanistan. We have been blamed in the past, but we were not involved."

单选题Talk to those people who first saw films when they were silent, and they will tell you the experience was magic. The silent film had extraordinary powers to draw members of an audience into the story, and an equally potent capacity of make their imaginations work. It required the audience to become engaged—to supply voices and sound effects. The audience was the final, creative contributor to the process of making a film. The finest films of the silent era depended on two elements that we can seldom provide today a large and receptive audience and a well-orchestrated score. For the audience, the fusion of picture and live music added up to more than the sum of the respective parts. The one word that sums up the attitude of the silent filmmakers is enthusiasm, conveyed most strongly before formulas took shape and when there was more room for experimentation. This enthusiastic uncertainty often resulted in such accidental discoveries as new camera or editing techniques. Some films experimented with players; the 1915 film Regeneration, for example, by using real gangsters and streetwalkers, provided startling local color. Other films, particularly those of Thomas Ince, provided tragic endings as often as films by other companies supplied happy ones. Unfortunately, the vast majority of silent films survive today in inferior prints that no longer reflect the care that the original technicians put into them. The modern versions of silent films may appear jerky and flickery, but the vast picture palaces did not attract four to six thousand people a night by giving them eyestrain. A silent film depends on its visuals; as soon as you degrade those, you lose elements that go far beyond the image on the surface. The acting in silent was often very subtle and very restrained, despite legends to the contrary.

单选题 Jonathan Swift made a famous Modest Proposal in 1729 that the babies of the Irish poor should be eaten to prevent them growing up to a poverty-stricken life of crime. It was, of course, ironic. But nearly 300 years later I would like to make a modest proposal about babies that is almost as astonishing, yet not at all ironic. I've come reluctantly to think, that perhaps some babies, in the public interest and to prevent them growing up to a life of violence, should be forcibly taken from their mothers and adopted. Freedom and compassion are two of the things I believe in most passionately and this proposal is entirely at odds with both, or so it seems. The image of little children being wrenched from the arms of their deeply upset mothers is one of the worst one can imagine. However, the parents of some of the criminally violent young people of today are not worthy of the name of mother or father. Some of those babies, given the extreme disadvantages of their upbringing, will grow up to torment, hurt and kill. All too often when a shocking murder is reported, it emerges that the killers had a background designed to produce such semi-psychotic violence. We could demand to know where the criminal justice system was in all this or why there are not police on the streets. But we don't often demand an explanation from the parents. Children from orderly homes do not tend to go about the streets looking for a fight. It is the children of the useless-there is no better word for it, I'm sorry to say-who go so tragically wrong. I am not talking about parents or children who suffer from mental illness; they can't be held responsible. I'm talking about parents who are pretty much in their fight minds, when not high on drink and drugs, and who choose to neglect their children, and who, neglecting or abusing those they have already, go on to have more. I mean never-married parents, with no standards, who have a string of partners coming and going, who have babies by different lovers, who are careless if those itinerants (partners) abuse their own children, who are running welfare scams or living by crime. What hope is there for their children? Now there's a challenge to politicians: stop talking about the cycle of deprivation and break it by taking away the babies and giving them to loving adoptive parents. A modest proposal, and a difficult one, but the only realistic one.

单选题{{B}}Passage Three{{/B}} Large, multinational corporations may be the companies whose ups and downs seize headlines. But to a far greater extent than most Americans realize, the economy's vitality depends on the fortunes of tiny shops and restaurants, neighborhood services and factories. Small businesses, defined as those with fewer than 100 workers, now employ nearly 60 percent of the work force and are expected to generate half of all new jobs between now and the year 2000. Some 1.2 million small firm have opened their doors over the past six years of economic growth, and 1989 will see an additional 200, 000 entrepreneurs striking off on their own. Too many of these pioneers, however, will blaze ahead unprepared. Idealists will overestimate the clamor for their products or fall to factor in the competition. Nearly everyone will underestimate, often fatally, the capital that success requires, Mid-career executives, forced by a takeover or a restructuring to quit the corporation and find another way to support themselves, may savor the idea of being their own boss but may forget that entrepreneurs must also, at least for a while, be bookkeeper and receptionist, too. According to Small Business Administration data, 24 of every, 100 businesses starting out today are likely to have disappeared in two years, and 27 more will have shut their doors four years from now. By 1995, more than 60 of those I00 start-ups will have folded. A new study of 3,000 small businesses, sponsored by American Express and the National Federation of Independent Business, suggests slightly better odds: Three years after start-up, 77 percent of the companies surveyed were still alive, Most credited their success in large part to having picked a business they already were comfortable in. Eighty percent had worked with the same product or service in their lest jobs. Thinking through an enterprise before the launch is obviously critical. But many entrepreneurs forget that a firms health in its pulse. In their zeal to expand, small-business owners often ignore early warning signs of a stagnant market or of decaying profitability. They hopefully pour more and more money into tile enterprise, preferring not to acknowledge eroding profit margins that mean the market for their ingenious service or product has evaporated, or that they must cut the payroll or vacate their lavish offices. Only when the financial well runs dry do they see the seriousness of the illness, and by then the patient is usually too far-gone to save. Frequent checks of your firm's vital signs will also guide you to a sensible rate of growth. To snatch opportunity, you must spot the signals that it is time to conquer new markets, add products or perhaps franchise your hot idea.

单选题This month is expected to see that seminal(有创意的)moment when digital cinema will outstrip the 35mm technology that has been the dominant projection format in movie theatres for over 120 years. In 2009, digital accounted for only 15% of global screens. But the movie Avatar changed all that. 3D movies required digital, and Avatar's phenomenal success with 3D pushed cinemas to adopt digital screens. IMS Screen Digest Cinema Intelligence Service estimates that by the end of 2012, digital will account for 63% of screens, and by 2015, 83% . A majority of those screens will be based on Texas Instruments' digital light processing(DLP)technology, a technology that uses millions of tiny mirrors on a tiny chip, each of them capable of moving thousands of times per second to create a digital image. That same technology today is also beginning to be used in cellphones and digital cameras to project images in those devices onto ordinary surfaces. That will be a bigger opportunity, says Kent Novak, Texas Instruments' senior VP for DLP products, who was in Bangalore recently. Cinemas are moving rapidly to digital screens. Why? The first digital movie was premiered(首演)in 1999. Initially it was thought moving to digital would givebetter picture quality and cost savings, but it took many years for a few systems to get deployed. And then Avatar happened. That was really the tipping point. In 2008, 153D movies were released; in 2009, it was close to 50. Theatres were able to get more people and get a higher price for the ticket, so it became a significant revenue generator. We have seen more conversion of film to digital in the last two years than in the previous ten. You are now bringing the technology to smaller devices. We are moving to put these chips into cellphones, digital still cameras, camcorders, laptop accessories, tablets, docking stations, media players. We've been hearing of pico(handheld)projectors for some time now. But we don't really see products in the market. The technology has only recently reached a tipping point in terms of lighting efficiency and total brightness. Three years ago, 1 watt of power could get the brightness measurement of about 5 lumens. Today that 1 watt can give 20 lumens(making the projected image brighter). We designed the chip to be more efficient. Also, the industry driver for efficiency is LED. The amount of investment going into LED is enormous. As technology has improved, volumes have gone up, and cost has come down. Micromax and Spice in India have put projection even in some of their feature phones; Samsung has put projection on some of their phones. Nikon has DLP embedded in some of their digital still cameras; Sony has them in camcorders. What are the use cases that you see? You can use your phone to show video clips, pictures, power point presentations, and make it a shared experience. India has been more progressive in adopting the technology because feature phones are a phone during the day and become the primary entertainment source in the evenings. India also has mobile TV phones with pre-loaded Bollywood movies that can be projected out of the phone.
