问答题Read the following passage and then give short answers to the following five questions. Most of us tell one two lies a day, according to scientists who study these things. And we rarely get caught, because the lies we tell are usually little ones: "I got stuck in traffic." "That color looks good no you." "I was just about to call." But even the smallest fib may soon be systematically exposed, at least in the virtual World. Researchers at several universities are developing software that can detect lies in online communications such as instant messages e-mails and chatrooms. The ability to spot "digital deception", as researchers call it, has never been more crucial. Today, much of our business and social life is conducted online, making us increasingly vulnerable. White collar criminals, sexual predators, scammers, identity thieves and even terrorists surf the same Web as the rest of us. Conventional lie detectors look for physiological signs of anxiety--a bead of sweat or a racing pulse--but online systems examine only the liar's words. "When we're looking at Ianguage, we're looking at the tool of the lie," says Jeff Hancock, all assistant professor of communication and a member of the faculty of computing and information science at Cornell University. Hancock, who recently received a $ 680, 000 grant from the National Science Foundation to study digital deception, says there is a growing body of evidence that the language of dishonest messages is different than that of honest ones. For example, one study led by Hancock and due to be published this spring in Discourse Processes found the deceptive e-mail messages contained 28 percent more words on average and used a higher percentage of words associated with negative emotions than did truthful messages. Liars also tend to use fewer first-person references (such as the pronoun "I") and more third-person references (such as "he" and "they"). This may be the liar's subconscious way of distancing himself from his lie. More surprising, Hancock and his colleagues have observed that the targets of liars also exhibit distinctive language patterns. For instance, people who are being deceived often use shorter sentences and ask more questions. Even though they may not be aware that they are being lide to, people seem to exhibit subconscious suspicions. To identify the patterns of deceit, Hancock has developed an instant-messaging system at Cornell that asks users to rate the deceptiveness of each message they send. The system has already collected 10, 000 messages, of which about 6 percent qualify as patently deceptive. Eventually the results will be incorporated into software that analyzes incoming messages. For now, the Cornell researchers are working only with the kinds of lies told be students and faculty. It remains to be seen whether such a system can be scaled up to handle "big" lies, such as messages sent by con artists and terrorists. Fortunately, the research so far suggests that people lie less often in e-mail than face-to-face or on the phone. Perhaps this is because people are reluctant to put their lies in writing, Hancock speculates. "An email generates multiple copies," he says. "It will last longer than something carved in rock." So choose your words carefully. The internet may soon be rid not only deceit but also of lame excuses.

问答题Storytelling isn"t just for old folks and kids. It can help you move forward in your career—both by showing what you"ve accomplished and by persuading employees to trust you. Stories can also aid hiring, says John Berisford, head of human resources at Pepsi Beverages. "I often ask one question, whether I"m interviewing a senior-level executive or a campus person: Tell me your story," said Berisford, who learned storytelling from his grandmother in West Virginia. "It"s the best way to get to know the entire human being." To instantly grasp the impact of a good yarn, think of bestselling books such as Fish! and Who Moved My Cheese? The ones that work are instantly memorable and forge emotional connections, says Katharine Hansen, Ph. D., co-owner of the Quintessential Careers website. But that doesn"t mean storytelling is right for every situation. "It can backfire if the teller is trying to build enthusiasm yet doesn"t feel it", says Simmons. Choosing the right story for your audience is crucial, as is editing it to be clear and concise. It also helps to be accurate; at a time when authenticity is scarce, no one wants to hear a tall tale.

问答题{{B}}Directions:{{/B}}Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written clearly on the ANSWER SHEET. Science fiction has a tendency to become science fact. Something like Hal, the on-board spaceship computer capable of ethical decision making and intelligence in Arthur Clarke's 2001: A space Odyssey, is being discussed seriously in modern artificial-intelligence (AI) laboratories. {{U}}{{U}} 1 {{/U}}{{/U}}{{U}}That is not to say that computers will evolve exactly as Clarke envisioned, any more than propulsion systems developed in the way Jules Verne imagined three-quarters of a century before a rocked sent a spaceship to the moon{{/U}}. {{U}}{{U}} 2 {{/U}}{{/U}}{{U}}However, computer scientists are developing systems that come very close to mimicking parts of human cognition; it seems plausible that something like Hal will be around before you depart from this earth{{/U}}. {{U}}{{U}} 3 {{/U}}{{/U}}{{U}}Computerized cognition, or artificial intelligence (AI), as it is often called, is broadly defined as that branch of computer science that deals with the development of computers (hardware) and computer programs (software) that emulate human cognitive functions{{/U}}. Cognition involves perception, memory, thinking, language processing and many other related functions which are carried out in a more or less exact way. You can, for example, see and recognize your friend' s face; compose a sensible poem set in iambic pentameter; mentally calculate the most direct route from your home to the college, and distinguish sour milk from fresh milk. We do things like this every day with no effort. We also do a lot of foolish things, such as put shampoo on our toothbrush. We are human-and that's a problem for computers, being perfect machines that never make a mistake, "computer errors" notwithstanding. If a computer could simulate human thought and actions precisely, then it would be as good as we are in doing the list of things mentioned earlier, but also be just as fallible as we are. {{U}}{{U}} 4 {{/U}}{{/U}}{{U}}It is important to recognize the distinction between those who want to write programs that will perform human tasks well, such as the program we are presently using that draws a squiggly red line under misspelled words and those who aim to clone human thought{{/U}}. Computers and their impressive programs have become such an indispensible part of our everyday life that we wonder how we got along without them—still, they aren't clever enough to shampoo with toothpaste. When we discuss AI, it is usually intertwined with Cognitive psychology and neuroscience. {{U}}{{U}} 5 {{/U}}{{/U}}{{U}}Ideas from one field, for example, neuroscience, might be incorporated into another, for example, artificial intelligence, and yet other ideas from cognitive psychology might be applied to both other areas{{/U}}.

问答题Directions: Write a summary of the following passage in no less than 80 words. Your summary should contain the main ideas of the original passage and be clearly written down on the AN SWER SHEET. In addition to food and shelter, man has a third basic need. This is clothing. Modern man wears clothing for three purposes: for protection, for decoration, and for modesty. It is thought that prehistoric man wore clothing for a fourth reason, as a kind of magic. For example, he may have worn the skins of animals either to celebrate his victories over them, or perhaps to gain strength and wisdom from the animals he had killed. Until fairly recently it was possible to use only natural materials of various kinds for the making of clothing. Both plants and animals supply these natural materials. From plants we get cotton and linen. From animals we get such materials as wool, silk, leather and furs. Wool was one of the first fibers to be used for cloth, and for a long time it was the most common textile fiber in Europe. The fiber which we call wool comes mainly from sheep, but the hair of a few other animals is also used for cloth. Cotton has been used for over three thousand years, especially in warm countries. Cotton material was not known in Europe until much later. Material made from the cotton plant can be very soft, cool and comfortable. The finest cotton materials were very expensive at one time, and only the rich people could buy them. Two other fibers, linen and silk, have also been used extensively in the making of clothing. In addition to the natural materials from plants and animals, modern man now has cloth which is made synthetically. In the twentieth century, man has learned to create completely synthetic fibers. These are made from coal, glass, petroleum, milk and wood. Nylon, dacron and orlon are the names of a few of these synthetic fibers. Recent synthetic products include disposable paper clothing and artificial leather. In many ways synthetic fibers are much better than natural fibers. It is possible to create specific fibers to be used for specific purposes. Of all the fibers now used by man, a very large percentage is man-made.
