What is the missing element that our theories don't yet {{U}}(51) {{/U}} for? The answer is simple: People read newspaper stories {{U}}(52) {{/U}} a reason to learn more about what they are interested in. Computers, on the other hand, don't. In fact, computers don't {{U}}(53) {{/U}} have interests; there is nothing in particular that they are trying to find out when they read. If a computer {{U}}(54) {{/U}} is to be a model of story understanding, it should also read for a "purpose". Of course, people have several goals that do not make {{U}}(55) {{/U}} to attribute to computers. One might read a restaurant guide in order to satisfy hunger or entertainment goals, or to {{U}}(56) {{/U}} a good place to go for a business lunch. Computers do not {{U}}(57) {{/U}}, and computers do not have business lunches. However, these physiological and social goals give {{U}}(58) {{/U}} to several intellectual or cognitive(认知的) goals. A goal to satisfy hunger gives rise to goals to find {{U}}(59) {{/U}} about the name of a restaurant which serves the desired type of food, how expensive the restaurant is, the {{U}}(60) {{/U}} of the restaurant, etc. These are goals to {{U}}(61) {{/U}} information or knowledge, what we are calling {{U}}(62) {{/U}} goals. These goals can be held by computers too a computer might "want" to find out the location of a restaurant, and read a guide in order to do so {{U}}(63) {{/U}} the same way as a person might. While such a goal would not {{U}}(64) {{/U}} out of hunger in the case of the com puter, it might {{U}}(65) {{/U}} rise out of the "goal" to learn more about restaurants.

单选题We can infer from the passage that

单选题Life in the Universe Many scientists today are convinced that life exists elsewhere in the universe-life probably much like that on our own planet. They reason in the following way. As far as astronomers can determine, the entire universe is built of the same matter. They have no reason to doubt that matter obeys the same laws in every part of the universe. Therefore, it is reasonable to guess that other stars, with their own planets, were born in the same way as our own solar system. What we know of life on earth suggests that life will arise wherever the proper conditions exist. Life requires the right amount and kind of atmosphere. This eliminates all those planets in the universe that are not about the same size and weight as the earth. A smaller planet would lose its atmosphere; a larger one would hold too much of it. Life also requires a steady supply of heat and light. This eliminates double stars, or stars that flare up suddenly. Only single stars that are steady sources of heat and light like our sun would qualify. Finally, life could evolve only if the planet is just the right distance from its sun. With a weaker sun than our own, the planet would have to be closer to it. With a stronger sun, it would have to be farther away. If we suppose that every star in the universe has a family of planets, then how many planets might support life? First, eliminate those stars that are not like our sun. Next eliminate most of their planets; they are either too far from or too close to their suns. Then eliminate all those planets which are not the same size and weight as the earth. Finally, remember that the proper conditions do not necessarily mean that life actually does exist on a planet. It may not have begun yet, or it may have already died out. This process of elimination seems to leave very few planets on which earthlike life might be found. However, even if life could exist on only one planet in a million, there are so many billions of planets that this would still leave a vast number on which life could exist.

单选题 Happy Marriage, Happy Heart Happily married people have lower blood pressure {{U}} {{U}} 1 {{/U}} {{/U}}unhappily married people or singles, a Brigham Young University study says. On the other hand, even having a supportive social network did not translate into a blood pressure benefit for singles or unhappily {{U}} {{U}} 2 {{/U}} {{/U}}people, according to the study. "There seem to be some unique health benefits from marriage. It's not just being married {{U}} {{U}} 3 {{/U}} {{/U}}benefits health—what's really the most protective of health is having a happy {{U}} {{U}} 4 {{/U}} {{/U}}." study author Julianne Holt-Lunstad, a psychologist who specializes in relationships and health, said in a prepared statement. The study included 204 married and 99 {{U}} {{U}} 5 {{/U}} {{/U}}adults who wore portable blood-pressure monitors for 24 hours. The {{U}} {{U}} 6 {{/U}} {{/U}}recorded blood pressure at random intervals and provided a total of about 72 readings. "We wanted to capture participants' blood pressure doing whatever they normally {{U}} {{U}} 7 {{/U}} {{/U}}in everyday life. Getting one or two readings in a clinic is not really {{U}} {{U}} 8 {{/U}} {{/U}}of the fluctuations that occur throughout the day," Holt-Lunstad said. Overall, happily married people scored four points {{U}} {{U}} 9 {{/U}} {{/U}}on the blood pressure readings than single adults. The study also found that blood {{U}} {{U}} 10 {{/U}} {{/U}}among married people—especially those in happy marriages {{U}} {{U}} 11 {{/U}} {{/U}}more during sleep than in single people. "Research has shown that people whose blood pressure remains high throughout the night are at {{U}} {{U}} 12 {{/U}} {{/U}}greater risk of heart disease than people whose blood pressure drops," Holt-Lunstad said. The study was published in the March 20 {{U}} {{U}} 13 {{/U}} {{/U}}of the journal Annals of Behavioral Medicine. The study also found that unhappily married adults have higher blood pressure than {{U}} {{U}} 14 {{/U}} {{/U}}happily married and single adults. Holt-Lunstad noted that married couples can encourage healthy habits in one {{U}} {{U}} 15 {{/U}} {{/U}}such as eating a healthy diet and having regular doctor visits. People in happy marriages also have a source of emotional support, she said.

单选题Electronic Teaching The potential of closed-circuit television and other new electronic leaching tools is so great that it is fascinating to visualize "the school of tomorrow". Televised lessons will originate from a central building having perhaps four or five master studios. The lessons will be carried into classrooms all over a city, or even an entire country. After a televised lesson has been given, the classroom teacher will take over for tire all-important "follow-up" period. The students will ask any troublesome questions, and difficult points will be cleared up through discussion. The teacher in the classroom will have additional electronic tools. On the teacher's desk, the traditional chalk and erasers will have been replaced by a multiple-control panel and magnetic tape players. The tape machines will run pre-recorded lessons which pupils will follow by headphones. The lessons will be specifically geared to the students' levels of ability. For instance, while the class as a whole studies history, each student will receive an individual history lesson, directed to his particular level of ability. Should question arise, the students will be able to talk directly to the teacher on individual intercoms without disturbing the rest of the class. In this way, the teacher will he able to conduct as many as three classes at the same time. With the rapid development of computer science, students will be aided with specially prepared multi-media software to study their subjects better. Homework will possibly be assigned and handed in via electronic mail system. Students can even take examinations on their computer linked with the teachers and get the score instantly. They will get certificates or diplomas if they pass all the required examinations. Experts believe that this type of education will be very popular in the years ahead.

单选题 下面有3篇短文，每篇短文后有5道题。请根据短文内容，为每题确定1个最佳选项。{{B}}第一篇{{/B}} {{B}}Happy Therapy (诊疗){{/B}} Norman Cousins was a businessman from the United States who often traveled around the world on business. He enjoyed his work and traveling. Then, after returning to the United States from a busy and tiring trip to Russia, Mr. Cousins got sick. Because he had pushed his body to the limit of its strength on the trip, a chemical change began to take place inside him. The material between his bones became weak. In less than one week after his return, he could not stand. Every move that he made was painful. He was not able to sleep at night. The doctors told Mr. Cousins that they did not know how to cure his problems and he might never get over the illness. Mr. Cousins, however, refused to give up hope. Mr. Cousins thought that unhappy thoughts were causing bad chemical changes in his body. He did not want to take medicine to cure himself. Instead, he felt that happy thoughts or laughter might cure his illness. He began to experiment on himself while still in the hospital by watching funny shows on television. Mr. Cousins quickly found that ten minutes of real laughter during the day gave him two hours of pain-free sleep at night. Deciding that the doctors could not help him, Mr. Cousins left the hospital and checked into a hotel room where he could continue his experiments with laughter. For eight days, Mr. Cousins rested in the hotel room watching funny shows on television, reading funny books, and sleeping whenever he felt tired. Within three weeks, he felt well enough to take a vacation to Puerto Rico where he began running on the beach for exercise. After a few months, Mr. Cousins returned to work. He had laughed himself back to health.

单选题The Anti- Alcohol Campaign Tries in Russia Last week Russian President Dmitry Medvedev kicked off a new anti - alcohol campaign aimed at cutting the nation's per capita consumption of alcohol by nearly a quarter by 2012. Russians currently drink about 18 liters (19 quarts) a year, more than double the 8 liters (8.4 quarts) deemed safe by the World Health Organization (WHO). With each additional liter, adds the WHO, men can subtract 11 months from their average life expectancy. The latest move consists of three parts: a media campaign, restrictions on beer consumption, and strict penalties for selling to minors. Russian officials plan to set up more than 500 health centers by the end of the year, complete with Soviet - era tactics like drawings of cimlosis (肝硬化) - stricken livers on their walls. Even with such aggressive measures, it' s hardly the most ambitious campaign Russians has ever launched against drinking. Former leader Mikhail Gorbachev got alcohol sales to decline by 60 percent. Three years ago, a group of young Russians organized a sort of Vigilante (治安维持会成员)vice squad to single out and shame merchants who sold alcohol to minors. Supported by the Moscow city administration, the Solar Circle movement, as they called themselves, held rallies, and slapped leaflets on the shop doors of guilty establishments. They piqued (激起，激发) media interest at first, but the momentum soon fizzled (渐停，夭折). Some critics say that, while admirable: it hardly addresses the biggest culprit of all: vodka. "The main problem is the availability of hard liquor," says Aleksandr Nemtsov, a top Russian expert on alcohol policy. Some 70 percent of alcohol consumption in Russia is of the hard stuff, primarily vodka. One attempt, tried in the mid - 1990s, substituted beer as a less intoxicating non - liquor alternative. Instead, "beer has become a gateway opening the way to alcoholism for teenagers," says Oleg Zykov, a member of the Public Chamber. The earlier people start down that route, the more likely they are to end up grappling with (尽力解决) alcoholism problems later. Still, for now, Russians seem to support the government' s new approach. As the National Center for the Study of Public Opinion reported last week, 65 percent of the population say they are in favor of the new measures - especially those that restrict alcohol sales to those under 21. (Right now, the drinking age is 18. )
