One immediate problem is to define thought,which is harder than you might think.The specialists in the field of artificial intelligence complain, with some justification, that anything that their machines do is dismissed as not being thought. For example, computer now plays very, very good chess.<br>They can&39;t beat the greatest players in the world, but they can beat just about anybody else.If a human being played chess at this level, he or she would certainly be considered smart.Why not a machine? The answer is that the machine doesn&39;t do anything clever in playing chess. It uses its blinding speed to do a brute force search of all possible moves for several moves ahead, evaluates the outcomes and picks the best.Human don&39;t play chess that way.They see patterns, while computers don&39;t.<br>This wooden approach to thought characterizes machine intelligence.Computers have no judgment, no common sense.So-called expert systems, one of the hottest areas in artificial intelligence aims to mimic the reasoning processes of human experts in a limited field, such as medical diagnosis or weather forecasting.There may be limited commercial applications for this sort of thing, but there is no way to make a machine that can think about anything under the sun, which a teenager can do.<br>The hallmark of artificial intelligence to date is that if a problem is severely restricted, a machine can achieve limited success.But when the problem is expanded to a realistic one computers fall fiat on their display screens.For example.machines can understand a few words spoken individually by a speaker that they have been trained to hear.They cannot understand continuous speech using an unlimited vocabulary spoken by just any speaker.<br>According to the passage, we know that the writer__________. 查看材料

Our bodies are estimated to be about 60% to 70% water.Blood is mostly water and our muscles, lungs, and brain all contain a lot of water.Water is needed to regulate body temperature and to provide the means for nutrients (滋养物 ) to travel to all our organs.Water also transports oxygen to our cells, removes waste, and protects our joints and organs.<br>2. We lose water through urination (排尿) , respiration (呼吸) , and by sweating.If you are very active,you lose more water than if you do not take much exercise, Symptoms of mild dehydration (脱水 ) include chronic pains in joints and muscles, lower back pain, headaches, and constipation (便秘) . A strong smell to your urine, along with a yellow color indicates that you are not getting enough water. Thirst is all obvious sign of dehydration and in fact, you need water long before you feel thirsty.<br>3.A good rule of thumb (好的做法 ) is to take your body weight in pounds and divide that number in half.That gives you the number of ounces (盎司 ) of water per day that you need.For example, if you weigh 160 pounds, you should drink at least 80 ounces of water per day,If you exercise you should drink another 8 ounces glass of water for every 20 minutes you are active. If you drink coffee or alcohol, you should add at least an equal amount of water.When you are traveling on an airplane, it is good to have 8 ounces of water for every hour you are on board the plane.<br>4. It may be difficult to drink enough water on a busy day. Be sure you have water handy at all times by keeping a bottle for water with you when you are working, traveling, or exercising.If you get bored with plain water, add a bit of lemon for a touch of flavor.There are some brands of flavored water available, but some of them have sugar or artificial sweeteners that you don&39;t need.<br>Paragraph 1__________. 查看材料

Other people always wake up with vivid recollections (记忆 ) of their dreams, though they forget them very quickly. In an average night of eight hours&39;sleep, an average adult will dream for around one hundred minutes, probably having three to five dreams, each lasting from ten to thirty minutes.<br>Scientists can detect when someone is having a dream by using an instrument which measures the electrical waves in the brain. During dreaming, these waves move more quickly. Breathing and pulse rate also increase, and there are rapid eye movements under the lids, just as though the dreamer were really looking at moving objects. These signs of dreaming have been detected in all mammals (哺乳动物) studied, including dogs, monkeys, cats, and elephants, and also some birds and reptiles (爬行动物) .This period of sleep is called the "D" state for around 50% of their sleep; the period reduces to around 25% by the age of 10.<br>Dreams take the form. of stories, but they may be strange and with incidents not connected, which make little sense. Dreams are seldom without people in them and they are usually about people we know. One estimate says that two-thirds of the "cast" of our dream dramas are friends and relations. Vision seems an essential part of dreams, except for people blind from birth. Sound and touch senses are also often aroused, but smell and taste are not frequently involved. In "normal" dreams, the dreamer may be taking part, or be only an observer. But he or she cannot control what happens in the dream.<br>However, the dreamer does have control over one type of dream. This type of dream is called a "lucid"(清醒的) dream. Not everyone is a lucid dreamer. Some people are occasional lucid dreamers. Others can dream lucidly more or less all the time. In a lucid dream, the dreamer knows that he is dreaming.<br>Some people dream but cannot remember their dreams. 查看材料

- 阅读材料,回答题。<br>The Influence of Western Movie<br>Whv does the Western movie especially have such a hold(影响)on our inclination?Chiefly,because it offers serious insights into the problem of violence such as can be found almost nowhere else in our culture.One of the well—known peculiarities of modem civilized opinion is its refusal to acknowledge the value of violence.This refusal is a virtue.but like many virtues it involves a certain deliberate blindness and it encourages hypocrisy(虚伪).We train ourselves to be shocked or bored by cultural images of violence,and our very concept of heroism tends to be a passive one.We are less drawn to the brave young men who kill large numbers of our enemies than to the heroic prisoners who endure torture without surrendering.And in the criticism of popular culture,the presence of images of violence is often assumed to be in itself a sufficient ground for condemnation.<br>These attitudes,however,have not reduced the element of violence in our culture but have helped to free it from moral control by letting it take on the air of“liberation”.The celebration of acts of violence is left more and more to the irresponsible.The gangster(匪徒)movie,with its numerous variations belongs to a cultural“underground”which praises violence aid sets it against all our higher social attitudes.It is a more“modem”style. than the Western movie,perhaps even more profound,because it confronts industrial society on its own ground—the city and because,like much of our advanced art,it gains its effects by a coarse insistence on its own narrow logic.But it is anti-social resting on fantasies of irresponsible freedom.If we are brought finally to concede to the denial of these fantasies,it is only because they have been shown to be dangerous,not because they have given way to higher values of behavior.<br>In war movies,certainly,it is possible to present violence within a framework of responsibility.But there is the disadvantage that modem war is a co-operative enterprise in which violence is largely impersonal and heroism belongs to the group more than to the individual.The hero of a war movie is most often simply a leader supposed to be brave;you are supposed to get the job done and stay alive(this too,of course,is a kind of heroic posture,but a new and“practical”one).At its best,the war movie may represent a more civilized point of view than the Western,and if it were not continually spoiled by ideological sentimentality we might hope to find it developing into a higher form. of drama.But it cannot supply the values we seek in the Western.<br>The author considers gangster movies to be__________. 查看材料
