9、gerous, boring, burdensome, or just plain nasty. That compulsion has resulted in robotics-the science of conferring various human capabilities on machines. And if scientists have yet to create the mechanical version of science fiction, they have begun to come close. As a result, the modem world is i
10、ncreasingly populated by intelligent gizmos whose presence we barely notice but whose universal existence has removed much human labor. Our factories hum to the rhythm of robot assembly arms. Our banking is done at automated teller terminals that thank us with mechanical politeness for the transacti
11、on. Our subway trains are controlled by tireless robot drivers. And thanks to the continual miniaturization of electronics and micromechanics, there are already robot systems that can perform some kinds of brain and bone surgery with submillimeter accuracy-far greater precision than highly skilled p
12、hysicians can achieve with their hands alone. But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at least a few decisions for themselves-goals that pose a real challenge. “While we know how to tell a robot to ha
13、ndle a specific error,“ says Dave Lavery, manager of a robotics program at NASA, “we can“t yet give a robot enough “common sense“ to reliably interact with a dynamic world.“ Indeed the quest for true artificial intelligence has produced very mixed results. Despite a spell of initial optimism in the
14、1960s and 1970s when it appeared that transistor circuits and microprocessors might be able to copy the action of the human brain by the year 2010, researchers lately have begun to extend that forecast by decades if not centuries. What they found, in attempting to model thought, is that the human br
15、ain“s roughly one hundred billion nerve cells are much more talented-and human perception far more complicated-than previously imagined. They have built robots that can recognize the error of a machine panel by a fraction of a millimeter in a controlled factory environment. But the human mind can gl
16、impse a rapidly changing scene and immediately disregard the 98 percent that is irrelevant, instantaneously focusing on the monkey at the side of a winding forest road or the single suspicious face in a big crowd. The most advanced computer systems on Earth can“t approach that kind of ability, and n

21、assage 2(总题数：1，分数：20.00)As video game images become increasingly more realistic and graphic, policy makers are debating if there is a link between the violence depicted in those games and violence in real life. A 20-year-old gunman“s shooting spree at a school in the northeastern America this month
22、has reinvigorated discussions about violence, prompting lawmakers to call for greater examination of brutality in video games. “But evidence does not suggest violence in games causes violence in life,“ says James Ivory, a professor in the university“s department of communication who researches the e
23、ffects of video games. “The agreement is pretty well universal among social scientists that there is not a clearly established link between actual violent crime and violent media usage,“ says Ivory. He adds that it is possible, though debated, that exposure to violent video games could make a person
24、 think or respond more aggressively in a short term, in Ivory“s words, “might even make you potentially more of a jerk to somebody.“ But he emphasizes, temporary aggression and violent crime are worlds apart. Wayne LaPierre, head of the National Rifle Association, disagrees. He maintains that there
25、exists in this country sadly a callous, corrupt and corrupting shadow industry that sells and sows violence against its own people, through vicious, violent video games. He named the popular game “Grand Theft Auto“ as an example. One of the creators of “Grand Theft Auto“, Navid Khonsari, says he gre
26、w up playing video games in Iran, Canada and the U.S. , where video games were enjoyed by people of all ages. “The discerning factor among the countries,“ says Khonsari, “is that while video games have been readily available, what has been limited is the accessibility to weapons. The focus on virtua
27、l violence might be limiting substantive discussions about firearm regulations and mental health treatment. “When we talk about violent video games and actual violent crime, we“re chasing something that hasn“t really been observed and we“re not talking about other things that have been observed,“ sa
28、ys Ivory. Despite the renewed focus on video game violence, investigators of the most recent U.S. school shooting have not said whether the young gunman was a player of violent video games. Interest in video games continues to grow around the globe. Analysts estimate people spent about 70 billion wo
29、rldwide on video games and components in 2012. North America, Western Europe and East Asia remain key markets, while gaming is on the rise in India, Brazil, Russia and Southeast Asia.（分数：20.00）(1).What“s the feature of the present day video games?（分数：4.00）A.They contain too much violence.B.They seem

34、总题数：1，分数：5.00)Many doctors suspect that there may be some relationship between emotions and illness. How ever, they can not find a proof. It is until two decades ago when Louise Hay brings her books You Can Heal Your Body and You Can Heal Your Life to us, things get clear in our mind. In her book, o
35、ver three hundred people were assessed in terms of their emotions for a two-week period. They were assessed for positive emotions they might be feeling, such as vigor, well-being, and calmness, as well as for negative emotions such as depression, anxiety, and hostility. Then they were each given a s
36、quirt in the nose of the virus that causes common cold. People with more positive emotional states were less likely to suffer from symptoms of the cold than people with negative emotional states and they restored to health in a short time. So there really does seem to be a link between emotional sta
37、te and illness. According to her research, our emotions are fundamentally connected with all aspects of health. This belief is widely accepted by numerous medical workers. Some physical problems are linked to emotional well-being. Our body and emotion are dependent on each other for us to be healthy
38、. Chinese traditional medical theories also hold the same idea that excitement does harm to the heart, anger to the liver, depression to the lung, and fears to the kidney. The immune system forms a solid protection to us. Whether or not we are likely to get disease depends on the work of our immune
39、system. A person often feeling distressed may feel dizzy and develop heart disease, and the person feeling fearful is likely to get insomnia. Back pain has been attributed to a feeling of not being emotionally supported. Headache can be caused by a kind of strain from life and work. However, many of
40、 us must have experienced the miracle that the euphoria of a good day makes our ache go away. A positive person is more immune to the attack of diseases. Studies show that the system is in connection with our emotions. Therefore, emotions can be influential to one“s mental and physical health. A hap
41、py patient with cancer may live longer than a depressed and disappointed patient. This is why many doctors help patients to release emotional strain besides the physical treatment. One should keep happy all the time. Only by this way, one can make his life better and healthier.（分数：5.00）(1).From the
42、first paragraph we leant that（分数：1.00）A.the connection of emotions and illness is first found among doctors.B.the doctors are not sure whether emotions influence illness.C.Louise Hay is an extraordinary doctor and she is widely accepted.D.Louise Hay solves many medical problems, so she is popular am
43、ong doctors.(2).How many examples are cited in this passage to illustrate that the emotions are associated with illness?（分数：1.00）A.4B.5C.6D.7(3).The text implies that（分数：1.00）A.a man who is feeling high pressure is likely to get headache.B.a man often with a low spirit is likely to be indigestible.C
44、.hysteria does harm to the lung.D.the best way to treat a patient is keep him happy all the time.(4).The fact that “the euphoria of a good day makes our ache go away“ can illustrate that（分数：1.00）A.Louise Hay“s book has a visible affect on diseases.B.positive attitude helps us to be immune to illness

46、ssage 4(总题数：1，分数：5.00)Recent research had claimed that an excess of positive ions (离子) in the air can have an illeffect on people“s physical or psychological health. What are positive ions? Well, the air is full of ions, electrically charged particles, and generally there is a rough balance between
47、the positive and the negative charges. But sometimes this balance becomes disturbed and a larger proportion of positive ions are found. This happens naturally before thunderstorms, earthquakes or when winds are blowing in certain countries. Or it can be caused by a build-up of static electricity ind
48、oors from carpets or clothing made of man-made fibers, or from TV sets, duplicators or computer display screens. When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches, fatigue, irritability, and some particularly sensitive people suff
49、er nausea (恶心) or even mental disturbance. Animals are also found to be affected, particularly before earthquakes; snakes have been observed to come out of hibernation (冬眠), rats to flee from their burrows, dogs howl and cats jump about unaccountably. This has led the U.S. Geographical Survey to fund a network of volunteers to watch animals in all effort to foresee such disasters before they hit vulnerable areas such as California. Conversely, when large numbers of negative ions are present, then people have a feeling of well-being. Natural conditions that produce these large am
