At least, that is what most men are convinced of. Psychologists view the subject either as a matter of frustration or a joke. Now the biologists have moved into this minefield, and some of them have found that there are real differences between the brains of men and women. But being different, they point out hurriedly, is not the same as being better or worse.There is, however, a definite structural variation between the male and female brain. The difference is in a part of the brain that is used in the most complex intellectual processes —the link between the two halves of the brain.The two halves are linked by a trunk line of between 200 and 300 million nerves, the corpus callosum (胼胝体). Scientists have found quite recently that the corpus callosum in women is always larger and probably richer in nerve fibers than it is in men. This is the first time that a structural difference has been found between the brains of women and men and it must have some significance. The question is "What?", and, if this difference exists, are there others? Research shows that present-day women think differently and behave differently from men. Are some of these differences biological and inborn, a result of evolution? We tend to think that is the influence of society that produces these differences. But could we be wrong?Research showed that these two halves of the brain had different functions, and that the corpus callosum enabled them to work together. For most people, the left half is used for word-handing, analytical and logical activities; the right half works on pictures, patterns and forms. We need both halves working together. And the better the connections, the more harmoniously the two halves work. And, according to research findings, women have the better connections.But it isn"t all that easy to explain the actual differences between skills of men and women on this basis. In schools throughout the world girls tend to be better than boys at "language subjects" and boys better at maths and physics. If these differences correspond with the differences in the hemispheric trunk line, there is an unalterable distinction between the sexes.We shan"t know for a while, partly because we don"t know of any precise relationship between abilities in school subject and the functioning of the two halves of the brain, and we cannot understand how the two halves interact via the corpus callosum. But this striking difference must have some effect and, because the difference is in the parts of the brain involved in intellect, we should be looking for differences in intellectual processing.（分数：5.00）(1).Which of the following statement is CORRECT?（分数：1.00）A.Biologists are conducting research where psychologists have given up.B.rain differences point to superiority of one sex over the other.C.Results of scientific research fail to support popular belief.D.The structural difference in the brain between the sexes has long been known.(2).According to the passage it is commonly believed that brain differences are caused by ______ factors.（分数：1.00）A.biologicalB.psychologicalC.physicalD.social(3)."These differences" in paragraph 5 refer to those in ______.（分数：1.00）A.skills of men and womenB.school subjectsC.the brain structure of men and womenD.activities carried out by the brain(4).At the end of the passage the author proposes more work on ______.（分数：1.00）A.the brain structure as a wholeB.the functioning of part of the brainC.the distinction between the sexesD.the effects of the corpus callosum(5).What is the main purpose of the passage?（分数：1.00）A.To outline the research findings on the brain structure.B.To explain the link between sex and brain structure.C.To discuss the various factors that cause brain differences.D.To suggest new areas in brain research.十三、Passage Two(总题数：1，分数：5.00)Can electricity cause cancer? In a society that literally runs on electric power, the very idea seems preposterous. But for more than a decade, a growing band of scientists and journalists has pointed to studies that seem to link exposure to electromagnetic fields with increased risk of leukemia and other malignancies. The implications are unsettling, to say the least, since everyone comes into contact with such fields, which are generated by everything electrical, from power lines and antennas to personal computers and micro-wave ovens. Because evidence on the subject is inconclusive and often contradictory, it has been hard to decide whether concern about the health effects of electricity is legitimate—or the worst kind of paranoia.Now the alarmists have gained some qualified support from the U.S. Environmental Protection Agency. In the executive summary of a new scientific review, released in draft form late last week, the EPA has put forward what amounts to the most serious government warning to date. The agency tentatively concludes that scientific evidence "suggests a casual link" between extremelylow-frequency electromagnetic fields—those having very longwave-lengths—and leukemia, lymphoma and brain cancer, While the report falls short of classifying ELF fields as probable carcinogens, it does identify the common 60-hertz magnetic field as "a possible, but not proven, cause of cancer in humans".The report is no reason to panic—or even to lost sleep. If there is a cancer risk, it is a small one. The evidence is still so controversial that the draft stirred a great deal of debate within the Bush Administration, and the EPA released it over strong objections from the Pentagon and the White House. But now no one can deny that the issue must be taken seriously and that much more research is needed.At the heart of the debate is a simple and well-understood physical phenomenon: When an electric current passes through a wire, it generates an electromagnetic field that exerts forces onsurrounding objects. For many years, scientists dismissed any suggestion that such forces might be harmful, primarily because they are so extraordinarily weak. The ELF magnetic field generated by a video terminal measures only a few milligauss, or about one-hundredth the strength of the earth"s own magnetic field. The electric fields surrounding a power line can be as high as 10 kilovolts per meter, but the corresponding field induced in human cells will be only about 1 millivolt per meter. This is far less than the electric fields that the cells themselves generate. How could such minuscule forces pose a health danger? The consensus used to be that they could not, and for decades scientists concentrated on more powerful kinds of radiation, like X-rays, that pack sufficient wallop to knock electrons out of the molecules that make up the human body. Such "ionizing" radiations have been clearly linked to increased cancer risks and there are regulations to control emissions.But epidemiological studies, which find statistical associations between sets of data, do not prove cause and effect. Though there is a body of laboratory work showing that exposure to ELF fields can have biological effects on animal tissues, a mechanism by which those effects could lead to cancerous growths has never been found.The Pentagon is far from persuaded. In a blistering 33-page critique of the EPA report, Air Force scientists charge its authors with having "biased the entire document" toward proving a link. "Our reviewers are convinced that there is no suggestion that electromagnetic fields present in the environment induce or promote cancer," the Air Force concludes. "It is astonishing that the EPA would lend its imprimatur on this report." Then Pentagon"s concern is understandable. There is hardly a unit of the modem military that does not depend on the heavy use of some kind of electronic equipment, from huge ground-based radar towers to the defense systems built into every warship and plane.（分数：5.00）(1).The main idea of this passage is ______.（分数：1.00）A.studies on the cause of cancerB.controversial view-points in the cause of cancerC.the relationship between electricity and cancerD.different ideas about the effect of electricity on caner(2).The view-point of the EPA is ______.（分数：1.00）A.there is casual link between electricity and cancerB.electricity really affects cancerC.controversialD.low frequency electromagnetic field is a possible cause of cancer(3).Why did the Pentagon and White House object to the release of the report? Because ______.（分数：1.00）A.it may stir a great deal of debate among the Bush AdministrationB.every unit of the modem military has depended on the heavy use of some kind of electronic equipmentC.the Pentagon"s concern was understandableD.they had different arguments(4).It can be inferred from physical phenomenon ______.（分数：1.00）A.the force of the electromagnetic field is too weak to be harmfulB.the force of the electromagnetic field is weaker than the electric field that the cells generateC.electromagnetic field may affect healthD.only more powerful radiation can knock electron out of human body(5).What do you think ordinary citizens may do after reading the different arguments?（分数：1.00）A.They are indifferent.B.They are worried very much.C.The may exercise prudent avoidance.D.They are shocked.十四、Passage Three(总题数：1，分数：5.00)Here"s a familiar version of the boy-meets-girl situation. A young man has at last plucked up courage to invite a dazzling young lady out to dinner. She has accepted his invitation and he is overjoyed. He is determined to take her to the best restaurant in town, even if it means that he will have to live on memories and hopes during the month to come. When they get to the restaurant, he discovers that this ethereal creature is on a diet. She mustn"t eat this and she mustn"t eat that. Oh, but of course, she doesn"t want to spoil his enjoyment. Let him by all means eat as much fattening food as he wants: it"s the surest way to an early grave. They spend a truly memorable evening together and never see each other again.What a miserable lot dieters are! You can always recognize them from the sour expression on their faces. They spend most of their time turning their noses up at food. They are forever consulting calorie charts; gazing at themselves in mirrors; and leaping on to weighing-machines in the bathroom. They spend a lifetime fighting a losing battle against spreading hips, protruding tummies and double chins. Some wage all-out war on FAT. Mere dieting is not enough. They exhaust themselves doing exercises, sweating in sauna baths, being pummeled and massaged by weird machines. The really wealthy diet-mongers pay vast sums for "health cures". For two weeks they can enter a nature clinic and be starved to death for a hundred guineas a week. Don"t think it"s only the middle-aged who go in for these fads either. Many of these bright young things you see are suffering from chronic malnutrition: they are living on nothing but air, water and the goodwill of God. Dieters undertake to starve themselves of their own free will; so why are they so miserable? Well, for one thing, they"re always hungry. You can"t be hungry and happy at the same time. All the horrible concoctions they eat instead of food leave them permanently dissatisfied. Wonderfood is a complete food, the advertisement says. Just dissolve a teaspoonful in water. A complete food it may be, but not quite as complete as a juicy steak. And, of course, they"re always miserable because they feel so guilty. Hunger just proves too much for them and in the end they lash out and devour five huge guilt-inducing cream cakes at a sitting. And who can blame them? At least three times a day they are exposed to temptation. What utter torture it is always watching others tucking into piles of mouth-watering food while you munch a water biscuit and sip unsweetened lemon juice!What"s all this self-inflicted torture for? Saintly people deprive themselves of food to attain a state of grace. Unsaintly people do so to attain a state of misery. It will be a great day when all the dieters in the world abandon their slimming courses; when they hold out their plates and demand second helpings!（分数：5.00）(1).The best title for this passage is ______.（分数：1.00）A.On FatB.We Should All Grow Fat and Be HappyC.Many Diseases Are Connected with FatD.Diet Deprives People of Normal Life(2).Why do they never see each other again?（分数：1.00）A.Because it is a memorable evening.B.Because she lets him eat as much fattening food as he wants.C.Because she does not eat this and drink that.D.Because eating fattening food is the surest way to an early grave.(3).What"s the meaning of "lot" in the first line of Paragraph 2?（分数：1.00）A.Amount.B.Field.C.Fate.D.Group.(4).Which of the following ways is NOT mentioned for diet?（分数：1.00）A.Doing exercises.B.Not eating sugar.C.Not eating fat.D.Taking sauna baths.(5).What is the author"s attitude toward diet?（分数：1.00）A.Persuasive.B.Critical.C.Indifferent.D.Adversative.十五、Passage Four(总题数：1，分数：5.00)Educators are seriously concerned about the high rate of dropouts among the doctor of philosophy candidates and the consequent loss of talent to a nation in need of PhDs. Some have placed the dropouts loss as high as 50 percent. The extent of the loss was, however, largely a matter of expert guessing. Last week a well-rounded study was published. It was based on 22,000 questionnaires sent to former graduate students who were enrolled in 24 universities and it seemed to show many past fears to be groundless.The dropouts rate was found to be 31 per cent, and in most cases the dropouts, while not completing the Ph.D. requirement, went on to productive work. They are not only doing well financially, but, according to the report, are not far below the income levels of those who went on to complete their doctorates.Discussing the study last week, Dr. Tucker said the project was initiated because of the concern frequently expressed by graduate faculties and administrators that some of the individuals who dropped out of Ph.D. programs were capable of competing the requirement for the degree. Attrition at the Ph.D. level is also thought to be a waste of precious faculty time and a drain on university resources already being used to capacity. Some people expressed the opinion that the shortage of highly trained specialists and college teachers could be reduced by persuading the dropouts to return to graduate schools to complete the Ph.D. "The results of our research," Dr. Tucker concluded, "did not support these opinions."1. Lack of motivation was the principal reason for dropping out.2. Most dropouts went as far in their doctoral program as was consistent with their levels of ability or their specialities.3. Most dropouts are now engaged in work consistent with their education and motivation. Nearly 75 per cent of the dropouts said there was no academic reason for their decision, but those who mentioned academic reason cited failure to pass the qualifying examination, uncompleted research and failure to pass language exams. Among the single most important personal reasons identified by dropouts for non-completion of their Ph.D. program, lack of finances was marked by 19 per cent.As an indication of how well the dropouts were doing, a chart showed 2% in humanities were receiving $20,000 and more annually while none of the Ph. D."s with that background reached this figure. The Ph. D."s shone in the $7,500 to $15,000 bracket with 78% at that level against 50% for the dropouts. This may also be an indication of the fact that top salaries in the academic fields, where Ph. D."s tend to rise to the highest salaries, are still lagging behind other fields. As to the possibility of getting dropouts back on campus, the outlook was glum. The main condition which would have to prevail for at least 25% of the dropouts who might consider returning to graduate school would be to guarantee that they would retain their present level of income and in some cases their present job.（分数：5.00）(1).The author states that many educators feel that ______.（分数：1.00）A.steps should be taken to get the dropouts back to campusB.the dropouts should return to a lower quality school to continue their studyC.the Ph.D. holder is generally a better adjusted person than the dropoutD.the high dropouts rate is largely attributable to the lack of stimulation on the part of faculty members(2).Research has shown that ______.（分数：1.00）A.dropouts are substantially below Ph. D."s in financial attainmentB.the incentive factor is a minor one in regard to pursuing Ph.D. studiesC.the Ph.D. candidate is likely to change his field of specialization if he drops outD.about one-third of those who start Ph.D. work do not complete the work to earn the degree(3).Meeting foreign language requirements for the Ph. D. ______.（分数：1.00）A.is the most frequent reason for dropping outB.is more difficult for the science candidate than for the humanities candidateC.is an essential part of many Ph.D. programsD.does not vary in difficulty among universities(4).After reading the article, one would refrain from concluding that ______.（分数：1.00）A.optimism reigns in regard to getting Ph. D. dropouts to return to their pursuit of the degreeB.a Ph.D. dropout, by and large, does not have what it takes to learn the degreeC.colleges and universities employ a substantial number of Ph. Ｄ. dropoutsD.Ph. Ｄ."s are not earning what they deserve in nonacademic positions(5).It can be inferred that the high rate of dropouts lies in ______.（分数：1.00）A.salary for Ph.D. too lowB.academic requirement too highC.salary for dropouts too highD.1,000 positions十六、Passage Five(总题数：1，分数：5.00)Avian influenza is an infectious disease of birds caused by type A strains of the influenza virus. The disease, which was first identified in Italy more than 100 years ago, occurs worldwide. All birds are thought to be susceptible to infection with avian influenza, though some species are more resistant to infection than others. Infection causes a wide spectrum of symptoms in birds, ranging from mild illness to a highly contagious and rapidly fatal disease resulting in severe epidemics. The latter is known as "highly pathogenic avian influenza". This form is characterized by sudden onset, severe illness, and rapid death, with a mortality that can approach 100%. Fifteen subtypes of influenza virus are known to infect birds, thus providing an extensive reservoir of influenza viruses potentially circulating in bird populations. To date, all outbreaks of the highly pathogenic form have been caused by influenza A viruses of subtypes H5 and H7. Migratory waterfowl—most notably wild ducks—are the natural reservoir of avian influenza viruses, and these birds are also the most resistant to infection. Domestic poultry, including chickens and turkeys, are particularly susceptible to epidemics of rapidly fatal influenza. Direct or indirect contact of domestic flocks with wild migratory waterfowl has been implicated as a frequent cause of epidemics. Live bird markets have also played an important role in the spread of epidemics.Recent research has shown that viruses of low pathogenicity can, after circulation for sometimes short periods in a poultry population, mutate into highly pathogenic viruses. During a 1983-1984 epidemic in the United States of America, the H5N2 virus initially caused low mortality, but within six months became highly pathogenic, with a mortality approaching 90%. Control of the outbreak required destruction of more than 17 million birds at a cost of nearly US$ 65 million. During a 1999-2001 epidemic in Italy, the H7N1 virus, initially of low pathogenicity, mutated within。

(The condition was named by the Greeks from their word for crab, presumably because of its clawing, crablike growth). The incidence of cancer has risen dramatically in recent decades, primarily 1 cigarette smoking, and cancer is probably our most dreaded disease today. As a cause of death in the United States, cancer has climbed from less than 6 percent of all deaths in 1900 to over 20 percent today, 2 recent statistics. It is already the leading killer of women aged thirty to fifty-four. And add a killer of the overall population, it is second only to heart disease, 3 close to 430,000 deaths per year. This figure has risen annually since 1949, and if percent trends continue, cancer may well overtake heart disease as the number one cause of death.Can We Fight Cancer More Effectively Today?Although there is still much to be learned about cancer, our knowledge of the disease has grown steadily in recent years. We have a better understanding of the disease and are finding ways to 4 it. Early recognition of the signs of cancer, prompt diagnosis, and aggressive treatment by the appropriate means have made the word cancer less 5 than it used to be. Even people with forms of cancer that are still difficult to treat know that current techniques may 6 them to outwit the disease until improved treatment becomes available. Many cancer victims have hope where there was once despair.Even more important is the fact that some kinds of cancer are 7 caused by preventable factors —for example, 25 to 30 percent of all cancer deaths are related to cigarette smoking, and most skin cancer is caused by 8 exposure to the sun. Not all forms of cancer have such obvious associations, but where risk factors have been 9 , we can use this knowledge and attempt to reduce the odds of developing those particular forms of disease. You and the people you know can 10 your cancer risk as individuals.（分数：10.00）A.prior toB.due toC.according toD.concerningA.based onB.on the basisC.concerningD.due toA.leading toB.resulting fromD.relating toA.consultB.cope withC.developD.give onA.frightenedB.terrifyingC.identifyingD.circulatingA.adviseB.approveC.enableD.ariseA.in sequenceB.in partC.in turnD.in additionA.extensiveB.intensiveC.massiveD.excessiveA.postponedB.predictedC.presentedD.establishedA.reduceB.destroyC.scratchD.exclude十一、PartⅣ Reading Compre(总题数：0，分数：0.00)十二、Passage One(总题数：1，分数：5.00)When people are struck by lightening, they fall to the ground as though they were struck by a severe blow to the head. After the shock they may remain unconscious, become semiconscious or be conscious but confused and dazed, at least for a time. Flashes of light may continue passing before their eyes, and blindness and deafness may follow. The nervous system may be badly affected, causing paralysis, pain in the limbs and even hemorrhage. There will be burns where the lightening passed through the body, and like all electrical bunts, they are often deep and sever.All persons, especially campers and hunters, should know how to give first aid to someone who has been struck by lightening. Do not be afraid to touch the victim. You won"t get a shock. The lightening has already been grounded. Remember that speed is of the greatest importance in severe cases.The first thing to do is to loosen tight clothing about the throat and waist. Then clear the air passages of mucus (黏液) if present, and apply artificial respiration if necessary. Give mouth-mouth resuscitation if needed, or give oxygen if available. Many victims thought to be dead have been revived after treatment.Send someone for a doctor as soon as possible, but don"t leave the victim alone. If a doctor is not available, take the person to a hospital as soon as the person can be safely moved. Signs of shock are: pale, cold, sticky skin; weak, rapid pulse; shallow, irregular breathing or,in extreme cases, no breathing at all. To treat shock, you must keep the patient lying down with the head lower than the feet and cover him or her with a blanket but watch out for overheating. Giving a stimulating hot tea or coffee will help, but only if the patient is thoroughly conscious. After breathing has been restored and shock is treated, treat the bums. Apply some salve and cover them with a clean cloth or a sterile dressing. If conscious, the patient will be badly frightened, so do all you can to reassure. A little knowledge and a helping hand may save someone"s life.（分数：5.00）(1).The passage mainly talks about ______.（分数：1.00）A.which metals conduct electricity bestB.where to go in a thunderstormC.how to treat someone struck by lighteningD.how to make mouth-to-mouth resuscitation(2).According to the passage, all the following are signs of shock except ______.（分数：1.00）A.abnormal feverB.cold skinC.irregular breathingD.rapid pulse(3).It can be guessed from the passage that ______.（分数：1.00）A.many campers and hunters are struck by lighteningB.cars are convenient for outdoor activitiesC.electric shock does little harm to the human bodyD.only professional nurses and doctors are allowed to give first aid(4).The word "salve" in line 2 of the last paragraph most likely means ______.（分数：1.00）A.spongeB.bandageC.ointmentD.liquid(5).Which of the following must not be done while treating shock?（分数：1.00）A.Giving the patient a cup of hot tea.B.Making the patient lie with the feet lower than the head.C.Covering the bums with a sterile dressing.D.Applying artificial respiration.十三、Passage Two(总题数：1，分数：5.00)Even as Americans have been gaining weight, they have cut their average fat intake from 36 to 34 percent of their total diets in the past 15 years. And indeed, cutting fat to control or lose weight makes sense. Fat has nine calories per gram. Protein and carbohydrates have just four. Moreover, the body uses fewer calories to metabolize fat than it does to metabolize other foods. Compared with protein and carbohydrates—which break down into amino acids and simple sugars, respectively, and can be used to strengthen and energize the body—dietary fat is more easily converted to body fat. Therefore, it"s more likely to stay on buttocks, thighs and bellies. But cutting fat from your diet doesn"t necessarily mean your body won"t store fat. For example, between nonfat and regular cookies, there"s trivial difference in calories because manufacturers make up for the loss of fat by adding sugar. Low-fat crackers, soups and dressings can also be just as high in calories as richer versions. No matter where the calories come from, overeating will still cause weight gain. The calories from fat just do it a little quicker. A Wisconsin computer programmer who decided with a diet coach to eat only 40 grams of fat a day learned the lesson firsthand. He wasn"t losing weight. Then he showed his food diary to his coach and revealed he"d been eating half a pound of jelly beans a day. "They don"t have any fat," he explains. But they had enough sugar to keep him from shedding an ounce.Nonfat foods become add-on foods. When we add them to our diet, we actually increase the number of calories we eat per day and gain weight. That was borne out in a Pennsylvania State University study. For breakfast, Prof. Barbara Rolls gave two groups of women yogurt that contained exactly the same amount of calories. One group"s yogurt label said "high fat"—the other, "low fat." The "low fat" yogurt group ate significantly more calories later in the day than the other group. "People think they"ve saved fat and can indulge themselves later in the day with no adverse consequences," says Richard Mattes, a nutrition researcher at Purdue University. "But when they do that, they don"t compensate very precisely, and they often end up overdoing it."（分数：5.00）(1).Why Americans are still gaining weight?（分数：1.00）A.They eat too much fat.B.They overeat.C.They eat low-fat crackers, soups and dressings.D.They eat sugar.(2).What lesson did the computer programmer learn?（分数：1.00）A.Overeating will cause weight gain.B.He can eat half a pound of jelly beans a day.C.He didn"t eat any fat.D.His coach gave him a lecture.(3).Prof. Barbara"s experiment proved that ______.（分数：1.00）A.Two groups ate the same amount of calories.B.Two groups ate the same amount of yogurt.C.The "low fat" yogurt group ate significantly more calories later in the day than the other group.D.People increase the number of calories they eat per day and gain weight.(4).According to the author, ______ has less calories.（分数：1.00）A.fatB.protein and carbohydratesC.amino acidD.sugar(5).What can you infer from the passage?（分数：1.00）A.To keep from being overweight, people have to eat non-fat food.B.The calories from fat just do it a little quicker than that from protein and carbohydrates.C.People should avoid temptation.D.Americans realize that it is necessary to count calories before eating the food.十四、Passage Three(总题数：1，分数：5.00)The elements other than hydrogen and helium exist in such small quantities that it is accurate to say that the universe is somewhat more than 75 percent hydrogen.Astronomers have measured the abundance of helium throughout our galaxy and in other galaxies as well. Helium has been found in old stars, in relatively young ones, in interstellar gas, and in the distant objects known as quasars. Helium nuclei have also been found to be constituents of cosmic rays that fall on the earth (cosmic "rays" are not really a form of radiation; they consist of rapidly moving particles of numerous different kinds). It doesn"t seem to make very much difference where the helium is found. Its relative abundance never seems to vary much. In some places, there may be slightly more of it; in others, slightly less, but the ratio of helium to hydrogen nuclei always remains about the same.Helium is created in stars. In fact, nuclear reactions that convert hydrogen to helium are responsible for most of the energy that stars produce. However, the amount of helium that could have been produced in this manner can be calculated, and it turns out to be no more than a few percent. The universe has not existed long enough for this figure to be significantly greater.Consequently, if the universe is somewhat more than 25 percent helium now, then it must have been about 25 percent helium at a time near the beginning.However, when the universe was less than one minute old, no helium could have existed. Calculations indicate that before this time temperatures were too high and particles of matter were moving around much too rapidly. It was only after the one-minute point that helium could exist. By this time, the universe had cooled sufficiently that neutrons and protons could stick together. But the nuclear reactions that led to the formation of helium went on for only a relatively short time. By the time the universe was a few minutes old, helium production had effectively ceased.（分数：5.00）(1).What does the passage mainly explain?（分数：1.00）A.How stars produce energy.B.The difference between helium and hydrogen.C.When most of the helium in the universe was formed.D.Why hydrogen is abundant.(2).According to the passage, helium is ______.（分数：1.00）A.the second-most abundant element in the universeB.difficult to detectC.the oldest element in the universeD.the most prevalent element in quasars(3).Why does the author mention "cosmic rays" in Paragraph 2?（分数：1.00）A.As part of a list of things containing helium.B.As an example of an unsolved astronomical puzzle.C.To explain how the universe began.D.To explain the abundance of hydrogen in the universe.(4).The creation of helium within stars ______.（分数：1.00）A.cannot be measuredB.produces energyC.produces helium to be much more abundant in old stars than in young starsD.produces carbon(5).Most of the helium in the universe was formed ______.（分数：1.00）A.in interstellar spaceB.in a very short timeC.during the first minute of the universe"s existenceD.before most of the hydrogen十五、Passage Four(总题数：1，分数：5.00)The bird flu virus is mutating and becoming more dangerous to mammals, according to researchers. The discovery reinforces fears that a human pandemic of the disease could yet occur. Avian flu hit the headlines in 1997 when a strain called H5N1 jumped from chickens to people, killing 6 people in Hong Kong. Within 3 days, the country"s entire chicken population was slaughtered and the outbreak was controlled. Since then new strains of virus have emerged, killing a further 14 people. As yet, no strain has been able to jump routinely from person to person. But if a more virulent strain evolves, the fear is that it could trigger widespread outbreaks, potentially affecting millions of people.Now, genetic and animal studies show that the virus is becoming more menacing to mammals. Immediate action is needed to stem the virus"s transmission, says Hualan Chen from Harbin Veterinary Research Institute, China, who was involved in the research. Chen and colleagues studied 21 H5N1 flu virus samples taken from apparently healthy ducks, which act as a natural reservoir for the disease, in southern China between 1999 and 2002. The researchers inoculated groups of chickens, mice and ducks with virus samples taken from different years and waited to see which animals became ill.Their results are presented this week in the Proceedings of the National Academy of Sciences . As expected, ducks were immune to the virus"s effects and the chickens fell sick. However, the mice also became ill, losing weight and the use of their limbs. Crucially, the severity of their illness was linked with the year from which the virus sample was taken. Viruses isolated in 2001 and 2002 made the animals more ill than those isolated earlier on.The findings hint that some time around 2001, the virus became adept at infecting mammals. Genetic analysis of the same samples reveals that the virus"s DNA changed over that time, suggesting that accumulated mutations may have contributed to the increased virulence.Researchers are concerned that a virus that has acquired the ability to infect mice could also infect humans. "The disease could resurge at any time," warns virologist Marion Koopmans from the National Institute of Public Health and the Environment in Bilthoven, the Netherlands. The findings highlight the need for improved surveillance to ensure that any future outbreaks are curtailed, she says. Although domestic poultry are easily culled, wild animals are more difficult to contain. "It is impossible to eradicate the natural reservoir," says Koopmans, "so we need to learn to live with it."Birds may not be the only villains in this story, however. Chen believes that pigs may also play a part. In Asia, chickens and pigs are often kept in close proximity, so the virus may have shuffled back and forth between the 2 species, picking up mutations and becoming better at infecting mammalian hosts. Humans may then have caught the disease from swine.（分数：5.00）(1).This passage is mainly concerned with ______.（分数：1.00）A.the spread of the bird flu virus to mammalsB.the domestic and wild poultry populationC.H5N1 isolated only from chickenD.a new virus strain jumping routinely from person to person(2).The fact that the H5NI virus was isolated from apparently healthy ducks suggests that ______.（分数：1.00）A.researchers worked real hardB.ducks were inoculated with H5N1 vaccineC.ducks might be a natural host of the virusD.the virus made animals sicker than other viruses(3).We can infer from Paragraph 3 that ______.（分数：1.00）A.the year in which the virus was isolated has nothing to do with the severity of illnessB.ducks are more likely to contract avian fluC.accumulated mutations have occurred in the H5N1 virusD.mice that are immune to the virus become sick(4).The findings show that the accumulated mutations ______.（分数：1.00）A.have been adept at infecting mammalsB.may have contributed to the increased virulence of the virusC.have led to the virus"s DNA changesD.require genetic analysis of the same samples(5).Koopman is convinced that human beings must learn to live with bird flu because ______.（分数：1.00）A.study findings highlight the need for improved surveillanceB.wild animals are easy to cullC.the disease could come back at any timeD.it is impossible to eliminate any natural host of the virus十六、Passage Five(总题数：1，分数：5.00)Neuroscientists now understand at least some of the physiology behind a wide range of unconscious states, from deep sleep to coma, from partially conscious conditions to a persistent vegetativestate, the condition diagnosed in Ms. Schiavo.New research, by laboratories in New York and Europe, has allowed for much clearer distinctions to be made between the uncounted number of people who at some time become comatose, the 10,000 to 15,000 Americans who subsist in vegetative states and the estimated 100,000 or more who exist in states of partial consciousness.This emerging picture should make it easier for doctors to judge which brain-damaged patients have some hope of recovering awareness, experts say, and already it is providing clues to the specific brain processes that sustain conscious awareness."Understanding what these processes are will give us a better sense of how to help the whole range of people living with brain injuries," said Dr. Nicholas Schiff, an assistant professor of neurology and neuroscience at NewYork-Presbyterian/Weill Cornell hospital. "That is where this field is ultimately headed: toward a better understanding of what consciousness is."The most familiar unconscious state is sleep, which in its deepest phases is characterized by little electrical activity in the brain and almost complete unresponsiveness. Coma, the most widely known state of impaired unconsciousness, is in fact a continuum. Doctors rate the extent to which a comatose person shows pain responses and reactions to verbal sounds on a scale from 3, for no response, to 13, for consistent responses.As in sleep, people in comas may move or make sounds and typically have no memory of either. But they almost always emerge from this state in two to three weeks, doctors say, when the eyes open spontaneously. What follows is critical for the person"s recovery.Those who are lucky, or who have less severe injuries, gradually awaken. "The first thing I remember was telling my ex-boyfriend, who was at the foot of the bed, to shut up," said Trisha Meili, who fell into a coma after being beaten and raped in 1990, and wrote about the experience in the book, I Am the Central Park Jogger .In the days after this memory, Ms. Meili said, she slipped in and out of conscious awareness, "as if my body was taking care of the most important things first, and leaving my moment to moment awareness for last."In fact, researchers say, this is precisely what happens. The primitive brain stem, which controls sleep-wake cycles as well as reflexes, asserts itself first, as the eyes open. Ideally, areas of the cerebral cortex, the seat of conscious thought, soon follow, like lights flicking on in the upper rooms of a darkened house.But in some cases—Ms. Schiavo"s was one of them—the cortical areas fail to engage, and the patient"s prognosis becomes dire.Neurologists were all but unanimous in diagnosing the condition of Ms. Schiavo, whose heart stopped temporarily in 1990, depriving her brain of oxygen. Brain cells and neural connections wither and die without oxygen, like marine life in a drained lake, leaving virtually nothing unharmed. People with these kinds of injuries—Nancy Cruzan, whose case reached the Supreme Court in 1990 is an example—almost always remain unresponsive if they have not regained awareness in the first months after the injury.In medical terms, they become persistently vegetative, a diagnosis first described in 1972 by Dr. Fred Plum of Cornell University and Dr. Bryan Jennett, a neurosurgeon at Glasgow University in Scotland. In a sense, the description of the diagnosis began the modem study of disorders of consciousness. "Before 1972 people talked about permanent comas, or irrecoverable comas, but we defined a different state altogether, with the eyes open, some reflex activity, but no sign of meaningful psychological responsiveness," Dr. Jennett, now a professor emeritus, said in an interview.In an exhaustive review of the medical histories of more than 700 persistently vegetative patients, a team of doctors in 1994 reported that about 15 percent of those who suffered brain damage from oxygen deprivation, like Ms. Schiavo, recovered some awareness within three months. After that,。

We also know that adults avoid eye contact when anxious. But researchers have knownfar 52 about eye gazing patterns in children.According to new research by Kalina Michalska, assistant professor of psychologyat the University of California, Riverside, we now, know that anxious children tend toavoid making eye contact, and this has consequences for how they experience fear. The53 and less frequently they look at the eyes of others, the more likely they are to beafraid of them, even when there may be no reason to be. Her study, “Anxiety Sympand Children's Eye Gaze During Fear Leaming”w,as published in the journal TheJournal of Child Psychology and Psychiatry."Looking at someone ’s eyes helps us understand whether a person is feeling sad, angry, fearful, or surprised. As adults, we then make decisions about how to respondand what to do next. But, we know much less about eye patterns in children —so,understanding those patterns can help us learn more about the development of sociallearning, ”Michalska said.Michalska and the team of researchersshowed 82 children, 9 to 13 years old,images of two women ’s faces on a computer screen. The computer was equipped withan eye tracking device that allowed them to measure54 on the screen children werelooking, and for how long. The participants were originally shown each of the twowomen a total of four times. Next, one of the images was55 with a loud scream anda fearful expression, and the other one was not. At the end, children saw both facesagain without any sound or scream.The following three conclusions can be drawn from the study:1. All children spent more time looking at the eyes of a face that was paired withthe loud scream t han the face that was not paired with the scream, 56 they payattention to potential threats even in the absence of outward cues.2. Children who were more anxious avoided eye contact during all three phases of the experiment, for both kinds of faces. This had consequences for how afraid they wereof the faces.3. The more children avoided eye conta；cthe more afraid they were 57 the faces.The conclusions suggest that children spend more time looking at the eyes of aface when previously paired with something frightening suggesting they pay moreattention to potentially threatening information as a way to learn more about thesituation and plan what to do next.However, anxious children tend to avoid making eye contact, which leads togreater 58 experience.

It has been argued that an infant under threewho is cared for outside the home may suffer because of the separation from his parents. But there are also arguments against such a strong conclusion.But traditional societies are so different from modem societies that comparisonsbased on just one factor are hard to interpret. Firstly, anthropologists point out that theinsulated love affair between children and parents found in modem societies does notusually exist in traditional societies. For example, in some tribal societies, such as theNgoni, the father and mother of a child did not rear their infant alone —far from i Certainty, Bowlby ’s analysis raises the possibilities that early day care had delayedeffects. The possibility that such care might lead to, say, more mental illness or crime15 or 20 years later can only explored by the use of statistics. However, statisticalstudies of this kind have not yet been carried out, and even if they were, the resultswould certainly be complicated and controversial. Secondly, common sense tells us that day care would not be so widespread today if parents, care-takers found children hadproblems with it. Thirdly, in the last decade, t here have been a number of careful American studies of children in day care, and they have uniformly reported that care had a neutral or slightly positive effect on children ’s development.Whatever the long-term effects, parents sometimes find the immediate effectsdifficult to deal with. Children under three are likely to protest at leaving their parentsand show unhappiness. At the age of three or three and a half almost all children findthe transition to nursery eas，yand this is undoubtedly why more and more parents make use of child care at this time. The matter, then, is far from clear-cut, though experienceand available evidence indicate early care is reasonable for infants.61. According to the passage, the consequence of parental separation________.A. still needs more statistical studiesB. has been found negative is more seriousC. is obviousD. in modem times62. The author thinks that John Bowlby ’s concern___________.A. is relevant and justifiableB. is too strong to RelieveC. is utterly groundlessD. has something that deserve our attention63. What ’s the result of American studies of children in day care in the last decade?A. The children ’s unhappiness and protest was due to the day care the children received.B. The bad effects of parental separation were hard to deal with.C. The effect of day care was not necessarily negative on children ’s development.D. Early care was reasonable for babies since it ’p sracti c ed by so many peoplenowadays.64. According to the passage, which of the following is probably a reason forparents to send their children under three to day care?A. They don ’t know about day care ’s negative effect.B. They are too busy to care fortheir children.C. They want their children to be independent as early as possible.D. They want to facilitate their children to adapt to nursery at the age of about three.65. What ’s the author ’s attitude to people who have drawn the conclusion fromBowlby’s work that children should not be subjected to day care before the age ofthree?A. He supports most of their belief because Bowlby's proposition is well-grounded.B. He is sympathetic for them, for he thinks they have been misled by Bowlby.C. He doesn't totally agree with them, since the long-term effect of day care still needsfurther study.D. He doesn't quite understand them, as they are contradictory in themselves.Passage TwoBy the end of this century, the average world temperature is expected to increasebetween one and four degrees, with widespread effects on rainfall, sea levels and animalhabitats. But in the Arctic, where the effects of climate change are most intense, the risein temperature could be twice as much.Understanding how Arctic warming will affect the people, animals, plant andmarine life and economic activity in Canada’N sort h are important to the country's future, says Kent Moore, an atmospheric physicist at University of Toronto Mississaugawho is participating in a long-term, international study of the marine ecosystem alongthe Beaufort Sea, from Alaska to the Mackenzie delta.The study will add to our knowledge of everything from the extent of sea ice inthe region to how fish stocks will change to which areas could become targets for oiland gas exploration to the impact on the indigenous people who call this part of thecountry home.Moore, who has worked in the Arctic for more than 20 years, says his research hasalready found that thinning sea ice and changes in wind patterns are causing animportant change in the marine food chain: phytoplankton（淳游植物） is blooming two to three weeks earlier. Manyanimals time their annual migration to the Arctic forwhen food is plentiful, and have not adapted to the earlier bloom. " ' Animals' behaviorcan evolve over a long time, but these climate changes are happening in the space of adecade, r ather than hundreds of years, ”says Moore, " Animals can't change theirbehavior that quickly. ”A warmer Arctic is expected to have important effects on human activity in theregion, as the Northwest Passage becomes navigable during the summer, and resourceextraction becomes more feasible. Information gained from the study will helpgovernment, industry and communities make decisions about resource management,economic development and environmental protection.Moore says the study — which involves Canadian, American and Europeanresearchersand government agencies will also use a novel technology to gatheratmospheric data: remotely piloted drones. "The drones have the capability of a largeresearch aircraft，and they ’re easier to deploy, ” he says, showing the researchers to gather information on a more regular basis than they would be able to with pilotedaircraft.66. By the end of this century, according to the author, global warming will ______.A. start to bring about extreme weather events to humans and animalsB. increase the average world temperature by four degreesC. cause more damages to the whole world than expectedD. affect the Arctic more than any other parts of the earth67. To help understand the destructive mechanism of Arctic warming, as indicatedby the passage, the international study ______.A. is conducted with every single discipline of University of TorontoB. pioneers in pursuing the widespread effects of climate changeC. involves so many countries for different investigationsD. is intended to deal with various aspects in research68. When he ways, “Animals can ’t change their behavior that quickly, ”what doesMoore mean by that quickly?A. The migration of the animals to the Arctic.B. The widespread effects of global warming.C. The rate of the climate change in the Arctic.D. The phytoplankton within the marine ecosystem.69. According to the author, to carry out proper human activities in theArctic______.A. becomes more difficult than ever beforeB. is likely to build a novel economy in the regionC. will surely lower the average world temperatureD. needs the research-based supporting information70. With the drones deployed, as Moore predicts, the researchers will _______.A. involve more collaborating countries than they do nowB. get more data to be required for their researchC. use more novel technologies in researchD. conduct their research at a regular basisPassage ThreeHaving too much caffeine during pregnancy may impair baby ’s liver development and increase the risk of liver disease in adulthood, according to a study published in theJournal of Endocrinology. Pregnant rats given caffeine had offspring with lower birth weights, altered growth and stress hormonelevels and impaired liver development. Thestudy findings indicate that consumption of caffeine equivalent to 2-3 cups of coffee may alter stress and growth hormone levels in a manner that can impair growth and development, and increase the risk of liver disease in adulthood.Previous studies have indicated that prenatal caffeine intake of 300 mg/day ormore in women, which is approximately 2 to 3 cups coffee per day, can result in lower birth weights of their children. Animalstudies have further suggestedthat prenatalcaffeine consumption may have more detrimental long-term effects on liverdevelopment with an increased susceptibility to non-alcoholic fatty liver disease, adebilitating condition normally associated w ith obesity and diabetes. However, theunderlying link between prenatal caffeine exposure and impaired liver developmentremains poorly understood. A better understanding of how caffeine mediates theseeffects could help prevent these health issues in people in the future.In this study, Prof Hui Wang and colleagues at Wuhan University in China,investigated the effects of low (equivalent to 2-3 cups of coffee) and high dose(equivalent of 6-9 cups of coffee) caffeine, given to pregnant rats, on liver function andhormone levels of their offspring. Offspring exposed to prenatal caffeine had lower levels of the liver hormone, insulin likegrowth factor (IGF-1), and higher levels of thestress hormone, corticosteroid at birth. However, liver development after birth showed a compensatory 'catch up' phase, characterised by increased levels of IGF-1, which is important for growth.Dr. Yinxian Wen, study co-author, says, “Our results indicate that prenatal caffeine causes an excess of stress hormone activity in the mother, which inhibits IGF-1 activityfor liver development before birth. However, compensatory mechanisms do occur after birth to accelerate growth and restore normalliver function, as IGF-1 activity increasesand stress hormone signalling decreases. The increased risk of fatty liver disease causedby prenatal caffeine exposure is most likely a consequence of this enhanced,compensatory postnatal IGF-1 activity. ”These findings not only confirm that prenatal caffeine exposure leads to lowerbirth weight and impaired liver development before birth but also expand our currentunderstanding of the hormonal changes underlying these changes and suggest thepotential mechanism for increased risk of liver disease in the future. However, theseanimal findings need to be confirmed in humans.Dr. Wen comments, "Our work suggeststhat prenatal caffeine is not good for babies and although these findingsstill need to be confirmed in people, I wouldrecommend that women avoid caffeine during pregnancy."71. Which of the following is NOT the problem of baby rats of pregnant rats givencaffeine?A. Lower birth weight.B. Smaller stress.C. Liver development problem.D. Growth problem.72. If a pregnant woman takes 3 cups of coffee, what will probably happen?A. Her weight will get lower and lower.B. The weight of her baby will get lower and lower.C. She will suffer from non-alcoholic fatty liver disease in a long run.D. Her baby will be more vulnerable to obesity and diabetes because of liver problem.73. Which of following is not correct according to the passage?A. A better understanding of the relationship between caffeine and effects has beenachieved.B. 4-5 cups of coffee could be categorized as medium-dose intake.C. Liver development problem may be remedied after birth by increased growth factor.D. The study is mainly conducted on the rats instead of human.74. What is the relationship between stress hormone and liver development whentaking in prenatal caffeine?A. Lower stress hormone, lower birth weight before birth.B. Higher stress hormone, lower growth hormone before birth.C. Higher stress hormone, more accelerated growth of weight after birth.D. Lower stress hormone, less accelerated growth of liver after birth.75. What can be the best summary of the last paragraph?A. The research hasn ’t been done on humans so pregnant women can ignore the results.B. The compensatory mechanism for liver growth makes prenatal caffeine intake safe.C. Experts suggest pregnant women should still avoid caffeine.D. We have known enough about the hormone changes underlying the healthPassage FourThe bizarre antics of sleepwalkers have puzzled police, perplexed scientists, and fascinated writers for centuries. There is an endless supply of stories about sleepwalkers.Persons have been said to climb on steep roofs, solve mathematical problems, composemusic, walk through plate-glass windows, and commit murder in their sleepHow many of these stories have a basis in fact, and how many are pure fakery?No one knows, but if some of the most sensational stories should be taken with a barrelof salt, others are a matter of record.In Revere, Massachusetts, a hundred policemen combed a waterfrontneighborhood for a lost boy who left his home in his sleep and woke up five hours lateron a strange sofa in a strange living room, with no idea how he had got there.There is an early medical record of a somnambulist who wrote a novel in his sleep.And the great French writer V oltaire knew a sleepwalker who once got out of bed,dressed himself, made a polite bow, danced a minuet, and then undressed and went backto bed.At the University of Iowa, a student was reported to have the habit of getting upin the middle of the night and walking three-quarters of a mile to the Iowa River. He would take a swim and then go back tohis room to bed.The world's champion sleepwalker was supposed to have been an Indian, PanditRamrakha, who walked sixteen miles along a dangerous road without realizing that hehad left his bed. Second in line for the title is probably either a Vienna housewife or a British farmer. The woman did all her shopping on busy streets in her sleep. The farmer,in his sleep, visited a veterinarian miles away.The leading expert on sleep in America claims that he has never seen a sleepwalker.He is Dr. Nathaniel Kleitman, a physiologist at the University of Chicago. He is said toknow more about sleep than any other living man, and during the last thirty-five yearshad lost a lot of sleep watching people sleep. Says he, "Of course, I know that there are sleepwalkers becauseI have read about them in the newspapers. B ut none of mysleepers ever walked, and if I were to advertise for sleepwalkers for an experiment, Idoubt that I'd get many takers."Sleepwalking, nevertheless, is a scientific reality. Like hypnosis, it is one of thosedramatic, eerie, awe-inspiring phenomena that sometimes border on the fantastic. Itlends itself to controversy and misconceptions, what is certain about sleepwalking isthat it is a symptom of emotional disturbance, and that the only way to cure it is to remove the worries and anxieties that cause it. Doctors say that somnambulism is muchmore common than is generally supposed.Some have estimated that there are fourmillion somnambulists in the United States. Others set the figure even higher. Manysleepwalkers do not seek help and so are never put on record, which means that anaccurate count can never be made.The simplest explanation of sleepwalking is that it is the acting out of a vividdream. The dream usually comes from guilt, worry, nervousness, o r some otheremotional conflict. The classic sleepwalker is Shakespeare ’L asdy Macbeth. Hernightly wanderings were caused by her guilty conscience at having committed murder. Shakespeare said of her, “The eyes are open but their sense is shut. ”The age-old question is: Is the sleepwalker actually awake or asleep. Scientists have decided that he is about half-and-half. Like Lady Macbeth, he has weightyproblems on his mind. Dr. Zeida Teplitz, who made a ten-year study of the subject, says, “Some people stay awake all night worrying about t heir problems. The sleepwalker thrashes them out in his sleep. He is awake in the muscular area, partially asleep in the sensory area." In other words, a person can walk in his sleep, move around, and do other things, but he does not think about what he is doing.76. The second sentence in the second paragraph means that_________.A. no one knows, but certainly all the sleep walking stories have something incredibleB. the sleepwalking stories are like salt adding flavor to people ’s lifeC. sleepwalking stories that are most fantastic should be sorted out from ordinary storiesD. the most fantastic sleepwalking stories may be just fictions, yet there are stilltruthfully recorded stories77. ________was supposed to be the world's champion sleepwalker.A. The student habitually walked to the Iowa River and swam in his sleepB. The man danced a minuet in his sleepC. The man walker sixteen miles along a dangerous roadD. The boy walked five hours in his sleep78. Sleepwalking is the result of ______ according to the passage.A. emotional disorderB. a vivid dreamC. lack of sleep and great anxietyD. insanity79. Dr. Zeida Teplitz seemed to_________.A. agree that sleepwalking sometimes leads to dangerous actsB. conclude that sleepwalkers are awake in their sensory areaC. disagree with the belief that sleep walkers are immune to injuryD. think that sleepwalking can turn into madness80. The writer makes it obvious that_________.A. sleepwalkers are often awakened by dangersB. most sleepwalkers can find ways to avoid self-injuryC. it is important to find out the underlying cause of sleepwalkingD. sleepwalking is actually a kind of hypnosisPassage FiveBeyond the basic animal instincts to seek food and avoid pain, Freud identifiedtwo sources of psychic energy, which he called "drives ”: aggression and libido. The keto his theory is that these were unconscious drives, shaping our behavior without themediation of our waking minds; they surface, heavily disguised, only in our dreams.The work of the past half-century in psychology and neuroscience has been to downplaythe role of unconscious universal drives, focusing instead on rational processesinconscious life. But researchers have found evidence that Freud s drives really do exist,and they have their roots in the limbic system, a primitive part of the brain that operatesmostly below the horizon of consciousness.Now more commonly referred to as emotions, the modem suite of drives comprises five: rage, panic, separation distress,lust and a variation on libido sometimes called seeking.The seeking drive is proving a particularly fruitful subject for researchers.Although like the others it originates in the limbic system, it also involves parts of theforebrain, the seat of higher mental functions. In the 1980s, Jaak Panksepp, aneurobiologist at Bowling Green State University in Ohio, became interested in a placenear the cortex known as the ventraltegmental area, which in humans lies just abovethe hairline. When Panksepp stimulated the corresponding region in a mouse, theanimal would sniff the air and walk around, as though it were looking for something.Was it hungry? No. The mouse would walk right by a plate of food, or for that matterany other object Panksepp could think of. This brain tissue seemed to cause a generaldesire for something new. “What I was seeing, ” he says, “was the urge to do stuff.Panksepp called this seeking.To neuropsychologist Mark Solms of University College in London, that soundsvery much like libido. “Freud needed some sort of general, appetitive desire to seekpleasure in the world of objects, ” says Solms. "Panksepp discovered as a neuroscientist what Freud discovered psychologically. ” Solms studied the same region of the brain forhis work on dreams. Since the 1970s, neurologists have known that dreaming takesplace during a particular form of sleep known as REM — rapid eye movement — whichis associated with a primitive part of the brain known as the pons. Accordingly, they regarded dreaming as a low-level phenomenon of no great psychological interest. WhenSolms looked into it, though, it turned out that the key structure involved in dreaming was actually the ventral tegmental, the same structure that Panksepp had identified as the seat of the “”s e e m k i o n t g i o n. Dreams, it seemed, originate with the libid—o which is just what Freud had believed.Freud's psychological map may have been flawed in many ways, but it alsohappensto be the most coherent and, from the standpoint of individual experience,meaningful theory of the mind. “Freud should be placed in the same category as Darwin,who lived before the discovery of genes, ” says Panksepp. “Freud gave us a vision ofmental apparatus. We need to talk about it, develop it, test it. ” Perhaps it ’sof proving Freud wrong or right, but of finishing the job.。

We also know that adults avoid eye contact when anxious. But researchers have known far 52 about eye gazing patterns in children.According to new research by Kalina Michalska, assistant professor of psychology at the University of California, Riverside, we now, know that anxious children tend to avoid making eye contact, and this has consequences for how they experience fear. The 53 and less frequently they look at the eyes of others, the more likely they are to be afraid of them, even when there may be no reason to be. Her study, “Anxiety Symptoms and Children's Eye Gaze During Fear Leaming”, was published in the journal The Journal of Child Psychology and Psychiatry."Looking at someone’s eyes helps us understand whether a person is feeling sad, angry, fearful, or surprised. As adults, we then make decisions about how to respond and what to do next. But, we know much less about eye patterns in children—so,understanding those patterns can help us learn more about the development of social learning,” Michalska said.Michalska and the team of researchers showed 82 children, 9 to 13 years old, images of two women’s faces on a computer screen. The computer was equipped with an eye tracking device that allowed them to measure 54 on the screen children were looking, and for how long. The participants were originally shown each of the two women a total of four times. Next, one of the images was 55 with a loud scream and a fearful expression, and the other one was not. At the end, children saw both faces again without any sound or scream.The following three conclusions can be drawn from the study:1. All children spent more time looking at the eyes of a face that was paired with the loud scream than the face that was not paired with the scream, 56 they pay attention to potential threats even in the absence of outward cues.2. Children who were more anxious avoided eye contact during all three phases of the experiment, for both kinds of faces. This had consequences for how afraid they were of the faces.3. The more children avoided eye contact；the more afraid they were 57 the faces.The conclusions suggest that children spend more time looking at the eyes of a face when previously paired with something frightening suggesting they pay more attention to potentially threatening information as a way to learn more about the situation and plan what to do next.However, anxious children tend to avoid making eye contact, which leads to greater 58 experience. Even though avoiding eye contact may reduce anxiety 59 , the study finds that—over time—children may be missing out 60_ important social information.

It has been argued that an infant under three who is cared for outside the home may suffer because of the separation from his parents. But there are also arguments against such a strong conclusion.But traditional societies are so different from modem societies that comparisons based on just one factor are hard to interpret. Firstly, anthropologists point out that the insulated love affair between children and parents found in modem societies does not usually exist in traditional societies. For example, in some tribal societies, such as the Ngoni, the father and mother of a child did not rear their infant alone—far from it.Certainty, Bowlby’s analysis raises the possibilities that early day care had delayed effects. The possibility that such care might lead to, say, more mental illness or crime 15 or 20 years later can only explored by the use of statistics. However, statistical studies of this kind have not yet been carried out, and even if they were, the results would certainly be complicated and controversial. Secondly, common sense tells us that day care would not be so widespread today if parents, care-takers found children had problems with it. Thirdly, in the last decade, there have been a number of careful American studies of children in day care, and they have uniformly reported that care had a neutral or slightly positive effect on childre n’s development.Whatever the long-term effects, parents sometimes find the immediate effects difficult to deal with. Children under three are likely to protest at leaving their parents and show unhappiness. At the age of three or three and a half almost all children find the transition to nursery easy，and this is undoubtedly why more and more parents make use of child care at this time. The matter, then, is far from clear-cut, though experience and available evidence indicate early care is reasonable for infants.61. According to the passage, the consequence of parental separation________.A. still needs more statistical studiesB. has been found negative is more seriousC. is obviousD. in modem times62. The author thinks that John Bowlby’s concern___________.A. is relevant and justifiableB. is too strong to RelieveC. is utterly groundlessD. has something that deserve our attention63. What’s the result of American studies of children in day care in the last decade?A. The children’s unhappiness and protest was due to the day car e the children received.B. The bad effects of parental separation were hard to deal with.C. The effect of day care was not necessarily negative on children’s development.D. Early care was reasonable for babies since it’s practiced by so many people nowadays.64. According to the passage, which of the following is probably a reason for parents to send their children under three to day care?A. They don’t know about day care’s negative effect.B. They are too busy to care for their children.C. They want their children to be independent as early as possible.D. They want to facilitate their children to adapt to nursery at the age of about three.65. What’s the author’s attitude to people who have drawn the conclusion from Bowlby’s work that children should not be subjected to day care before the age of three?A. He supports most of their belief because Bowlby's proposition is well-grounded.B. He is sympathetic for them, for he thinks they have been misled by Bowlby.C. He doesn't totally agree with them, since the long-term effect of day care still needs further study.D. He doesn't quite understand them, as they are contradictory in themselves.Passage TwoBy the end of this century, the average world temperature is expected to increase between one and four degrees, with widespread effects on rainfall, sea levels and animal habitats. But in the Arctic, where the effects of climate change are most intense, the rise in temperature could be twice as much.Understanding how Arctic warming will affect the people, animals, plant and marine life and ec onomic activity in Canada’s North are important to the country's future, says Kent Moore, an atmospheric physicist at University of Toronto Mississauga who is participating in a long-term, international study of the marine ecosystem along the Beaufort Sea, from Alaska to the Mackenzie delta.The study will add to our knowledge of everything from the extent of sea ice in the region to how fish stocks will change to which areas could become targets for oil and gas exploration to the impact on the indigenous people who call this part of the country home.Moore, who has worked in the Arctic for more than 20 years, says his research hasalready found that thinning sea ice and changes in wind patterns are causing an important change in the marine food chain: phytoplankton（淳游植物）is bloomingtwo to three weeks earlier. Many animals time their annual migration to the Arctic for when food is plentiful, and have not adapted to the earlier bloom. " ' Animals' behavior can evolve over a long time, but these climate changes are happening in the space of a decade, rather than hundreds of year s, ” says Moore, " Animals can't change their behavior that quickly. ”A warmer Arctic is expected to have important effects on human activity in the region, as the Northwest Passage becomes navigable during the summer, and resource extraction becomes more feasible. Information gained from the study will help government, industry and communities make decisions about resource management, economic development and environmental protection.Moore says the study—which involves Canadian, American and European researchers and government agencies will also use a novel technology to gather atmospheric data: remotely piloted drones. "The drones have the capability of a large research aircraft，and the y’re easier to deploy,” he says, showing the researchers to gather information on a more regular basis than they would be able to with piloted aircraft.66. By the end of this century, according to the author, global warming will ______.A. start to bring about extreme weather events to humans and animalsB. increase the average world temperature by four degreesC. cause more damages to the whole world than expectedD. affect the Arctic more than any other parts of the earth67.To help understand the destructive mechanism of Arctic warming, as indicated by the passage, the international study ______.A. is conducted with every single discipline of University of TorontoB. pioneers in pursuing the widespread effects of climate changeC. involves so many countries for different investigationsD.is intended to deal with various aspects in research68. When he ways, “Animals can’t change their behavior that quickly,” what does Moore mean by that quickly?A. The migration of the animals to the Arctic.B. The widespread effects of global warming.C. The rate of the climate change in the Arctic.D.The phytoplankton within the marine ecosystem.69. According to the author, to carry out proper human activities in the Arctic______.A. becomes more difficult than ever beforeB. is likely to build a novel economy in the regionC. will surely lower the average world temperatureD. needs the research-based supporting information70. With the drones deployed, as Moore predicts, the researchers will _______.A. involve more collaborating countries than they do nowB. get more data to be required for their researchC. use more novel technologies in researchD. conduct their research at a regular basisPassage ThreeHaving too much caffeine during pregnancy may impair baby’s liver development and increase the risk of liver disease in adulthood, according to a study published in the Journal of Endocrinology. Pregnant rats given caffeine had offspring with lower birth weights, altered growth and stress hormone levels and impaired liver development. The study findings indicate that consumption of caffeine equivalent to 2-3 cups of coffee may alter stress and growth hormone levels in a manner that can impair growth and development, and increase the risk of liver disease in adulthood.Previous studies have indicated that prenatal caffeine intake of 300 mg/day or more in women, which is approximately 2 to 3 cups coffee per day, can result in lower birth weights of their children. Animal studies have further suggested that prenatal caffeine consumption may have more detrimental long-term effects on liver development with an increased susceptibility to non-alcoholic fatty liver disease, a debilitating condition normally associated with obesity and diabetes. However, the underlying link between prenatal caffeine exposure and impaired liver development remains poorly understood. A better understanding of how caffeine mediates these effects could help prevent these health issues in people in the future.In this study, Prof Hui Wang and colleagues at Wuhan University in China, investigated the effects of low (equivalent to 2-3 cups of coffee) and high dose (equivalent of 6-9 cups of coffee) caffeine, given to pregnant rats, on liver function and hormone levels of their offspring. Offspring exposed to prenatal caffeine had lower levels of the liver hormone, insulin like growth factor (IGF-1), and higher levels of the stress hormone, corticosteroid at birth. However, liver development after birth showed a compensatory 'catch up' phase, characterised by increased levels of IGF-1, which is important for growth.Dr. Yinxian Wen, study co-author, says, “Our results indicate that prenatal caffeine causes an excess of stress hormone activity in the mother, which inhibits IGF-1 activity for liver development before birth. However, compensatory mechanisms do occur after birth to accelerate growth and restore normal liver function, as IGF-1 activity increases and stress hormone signalling decreases. The increased risk of fatty liver disease caused by prenatal caffeine exposure is most likely a consequence of this enhanced, compensatory postnatal IGF-1 activity. ”These findings not only confirm that prenatal caffeine exposure leads to lower birth weight and impaired liver development before birth but also expand our current understanding of the hormonal changes underlying these changes and suggest the potential mechanism for increased risk of liver disease in the future.However, these animal findings need to be confirmed in humans.Dr. Wen comments, "Our work suggests that prenatal caffeine is not good for babies and although these findings still need to be confirmed in people, I would recommend that women avoid caffeine during pregnancy."71. Which of the following is NOT the problem of baby rats of pregnant rats given caffeine?A. Lower birth weight.B. Smaller stress.C. Liver development problem.D. Growth problem.72. If a pregnant woman takes 3 cups of coffee, what will probably happen?A. Her weight will get lower and lower.B. The weight of her baby will get lower and lower.C. She will suffer from non-alcoholic fatty liver disease in a long run.D. Her baby will be more vulnerable to obesity and diabetes because of liver problem.73. Which of following is not correct according to the passage?A. A better understanding of the relationship between caffeine and effects has been achieved.B. 4-5 cups of coffee could be categorized as medium-dose intake.C. Liver development problem may be remedied after birth by increased growth factor.D. The study is mainly conducted on the rats instead of human.74. What is the relationship between stress hormone and liver development when taking in prenatal caffeine?A. Lower stress hormone, lower birth weight before birth.B. Higher stress hormone, lower growth hormone before birth.C. Higher stress hormone, more accelerated growth of weight after birth.D. Lower stress hormone, less accelerated growth of liver after birth.75. What can be the best summary of the last paragraph?A. The r esearch hasn’t been done on humans so pregnant women can ignore the results.B. The compensatory mechanism for liver growth makes prenatal caffeine intake safe.C. Experts suggest pregnant women should still avoid caffeine.D. We have known enough about the hormone changes underlying the healthPassage FourThe bizarre antics of sleepwalkers have puzzled police, perplexed scientists, and fascinated writers for centuries. There is an endless supply of stories about sleepwalkers. Persons have been said to climb on steep roofs, solve mathematical problems, compose music, walk through plate-glass windows, and commit murder in their sleepHow many of these stories have a basis in fact, and how many are pure fakery? No one knows, but if some of the most sensational stories should be taken with a barrel of salt, others are a matter of record.In Revere, Massachusetts, a hundred policemen combed a waterfront neighborhood for a lost boy who left his home in his sleep and woke up five hours later on a strange sofa in a strange living room, with no idea how he had got there.There is an early medical record of a somnambulist who wrote a novel in his sleep. And the great French writer Voltaire knew a sleepwalker who once got out of bed, dressed himself, made a polite bow, danced a minuet, and then undressed and went back to bed.At the University of Iowa, a student was reported to have the habit of getting up in the middle of the night and walking three-quarters of a mile to the Iowa River. He would take a swim and then go back to his room to bed.The world's champion sleepwalker was supposed to have been an Indian, Pandit Ramrakha, who walked sixteen miles along a dangerous road without realizing that he had left his bed. Second in line for the title is probably either a Vienna housewife or a British farmer. The woman did all her shopping on busy streets in her sleep. The farmer, in his sleep, visited a veterinarian miles away.The leading expert on sleep in America claims that he has never seen a sleepwalker. He is Dr. Nathaniel Kleitman, a physiologist at the University of Chicago. He is said to know more about sleep than any other living man, and during the last thirty-five years had lost a lot of sleep watching people sleep. Says he, "Of course, I know that there are sleepwalkers because I have read about them in the newspapers. But none of my sleepers ever walked, and if I were to advertise for sleepwalkers for an experiment, I doubt that I'd get many takers."Sleepwalking, nevertheless, is a scientific reality. Like hypnosis, it is one of those dramatic, eerie, awe-inspiring phenomena that sometimes border on the fantastic. It lends itself to controversy and misconceptions, what is certain about sleepwalking is that it is a symptom of emotional disturbance, and that the only way to cure it is to remove the worries and anxieties that cause it. Doctors say that somnambulism is much more common than is generally supposed. Some have estimated that there are four million somnambulists in the United States. Others set the figure even higher. Many sleepwalkers do not seek help and so are never put on record, which means that an accurate count can never be made.The simplest explanation of sleepwalking is that it is the acting out of a vivid dream. The dream usually comes from guilt, worry, nervousness, or some other emotional conflict. The classic sleepwalker is Shakespeare’s Lady Macbeth. Her nightly wanderings were caused by her guilty conscience at having committed murder. Shakespeare said of her, “The eyes are open but their sense is shut.”The age-old question is: Is the sleepwalker actually awake or asleep. Scientists have decided that he is about half-and-half. Like Lady Macbeth, he has weighty problems on his mind. Dr. Zeida Teplitz, who made a ten-year study of the subject, says, “So me people stay awake all night worrying about their problems. The sleepwalker thrashes them out in his sleep. He is awake in the muscular area,partially asleep in the sensory area." In other words, a person can walk in his sleep, move around, and do other things, but he does not think about what he is doing.76. The second sentence in the second paragraph means that_________.A. no one knows, but certainly all the sleep walking stories have something incredibleB. the sleepwalking stories are lik e salt adding flavor to people’s lifeC. sleepwalking stories that are most fantastic should be sorted out from ordinary storiesD. the most fantastic sleepwalking stories may be just fictions, yet there are still truthfully recorded stories77. ________was supposed to be the world's champion sleepwalker.A. The student habitually walked to the Iowa River and swam in his sleepB. The man danced a minuet in his sleepC. The man walker sixteen miles along a dangerous roadD. The boy walked five hours in his sleep78. Sleepwalking is the result of ______ according to the passage.A. emotional disorderB. a vivid dreamC. lack of sleep and great anxietyD. insanity79. Dr. Zeida Teplitz seemed to_________.A. agree that sleepwalking sometimes leads to dangerous actsB. conclude that sleepwalkers are awake in their sensory areaC. disagree with the belief that sleep walkers are immune to injuryD. think that sleepwalking can turn into madness80. The writer makes it obvious that_________.A. sleepwalkers are often awakened by dangersB. most sleepwalkers can find ways to avoid self-injuryC. it is important to find out the underlying cause of sleepwalkingD. sleepwalking is actually a kind of hypnosisPassage FiveBeyond the basic animal instincts to seek food and avoid pain, Freud identified two sources of psychic e nergy, which he called "drives”: aggression and libido. The key to his theory is that these were unconscious drives, shaping our behavior without the mediation of our waking minds; they surface, heavily disguised, only in our dreams. The work of the past half-century in psychology and neuroscience has been to downplay the role of unconscious universal drives, focusing instead on rational processes in conscious life. But researchers have found evidence that Freud s drives really do exist, and they have their roots in the limbic system, a primitive part of the brain that operates mostly below the horizon of consciousness. Now more commonly referred to as emotions, the modem suite of drives comprises five: rage, panic, separation distress, lust and a variation on libido sometimes called seeking.The seeking drive is proving a particularly fruitful subject for researchers. Although like the others it originates in the limbic system, it also involves parts of the forebrain, the seat of higher mental functions. In the 1980s, Jaak Panksepp, a neurobiologist at Bowling Green State University in Ohio, became interested in a place near the cortex known as the ventraltegmental area, which in humans lies just above the hairline. When Panksepp stimulated the corresponding region in a mouse, the animal would sniff the air and walk around, as though it were looking for something. Was it hungry? No. The mouse would walk right by a plate of food, or for that matter any other object Panksepp could think of. This brain tissue seemed to cause a general desire for some thing new. “What I was seeing,”he says, “was the urge to do stuff. ” Panksepp called this seeking.To neuropsychologist Mark Solms of University College in London, that sounds very much like libido. “Freud needed some sort of general, appetitive desire to seek pleasure in the world of objects,” says Solms. "Panksep p discovered as a neuroscientist what Freud discovered psychologically.” Solms studied the same region of the brain for his work on dreams. Since the 1970s, neurologists have known that dreaming takes place during a particular form of sleep known as REM—rapid eye movement—which is associated with a primitive part of the brain known as the pons. Accordingly, they regarded dreaming as a low-level phenomenon of no great psychological interest. When Solms looked into it, though, it turned out that the key structure involved in dreaming was actually the ventral tegmental, the same structure that Panksepp had identified as the seat of the “seeking”emotion. Dreams, it seemed, originate with the libido—which is just what Freud had believed.Freud's psychological map may have been flawed in many ways, but it also happens to be the most coherent and, from the standpoint of individual experience, meaningful theory of the mind. “Freud should be placed in the same category as Darwin, who lived before the discovery of genes,” says Panksepp. “Freud gave us a vision of a mental apparatus. We need to talk about it, develop it, test it.” Perhaps it’s not a matter of proving Freud wrong or right, but of finishing the job.81. Freud believed that aggression and libido________A. were the only two sources of psychic energyB. could sometimes surface in our conscious lifeC. affected our behavior unconsciouslyD. could appear clearly on our dreams82. Which of the following terms is equivalent to what Freud called libido?A. Emotion.B. Lust.C. Seeking.D. Urge.83. Jaak Panksepp's study on a mouse proves that the seeking drive________.A. originates in the limbic systemB. involves parts of the forebrainC. controls how we respond to stimulusD. exists in many, other animals。
