A,B,C and D on the right side.Choose the best answer and mark the letter of your choice on the ANSWER SHEET.It was the kind of research that gave insight into how flu strains could mutate so quickly.The same branch of research concluded in2005that the1918flu started in birds before passing to humans.Parsing this animal-human51could provide clues to52the next potential super flu,whichalready has a name:H5N1,also known as avian flu or bird flu.This potential killer also has a number:59%.According to the WHO,nearly three-fifths of the people who53H5NI since2003died from the virus,which was first reported54humans in Hong Kong in1997before a more serious55occurred in Southeast Asia between2003and2004.(It has since spread to Africa and Europe.)Some researchers argue that those mortality numbers are exaggerated because WHO only56cases in which victims are sick enough to go to the hospitals for treatment.57,compare that to the worldwide mortality rate of the1918pandemic;it may have killed roughly50million people,but that was only10%of the number of people infected,according to a2006estimate.H5NI’s saving grace—and the only reason we’re not running around masked up in public right now—is that the strain doesn’t jump from birds to humans,or from humans to humans,easily. There have been just over600cases(and359deaths)since2003.But58its lethality,and the chance it could turn into something far more transmissible,one might expect H5NI research to be exploding,with labs59the virus’s molecular components to understand how it spreads between animals and60to humans,and hoping to discover a vaccine that could head off a pandemic.51.A.rejection B.interface plement D.contamination52.A.be stopped B.stopping C.being stopped D.having stopped53.A.mutated B.effected C.infected D.contracted54.A.in B.on C.with D.from55.A.trigger unch C.outbreak D.outcome56.A.counts B.amounts to C.accounts for D.accumulates57.A.Thereafter B.Thereby C.Furthermore D.Still58.A.given B.regarding C.in spite of D.speaking of59.A.parses B.parsed C.parsing D.to parse60.A.potently B.absolutely C.potentially D.importantlyPart IV Reading Comprehension(30%)Directions:In this part,there are six passages,each of which is followed by five questions.For each question,there are four possible answers marked A,B,C,and D.Choose the best answer and mark the letter of your choice on the ANSWER SHEET.Passage OneIf you are reading this article,antibiotics have probably saved your life—and not once but several times.A rotten tooth,a knee operation,a brush with pneumonia;any number of minor infections that never turned nasty.You may not remember taking the pills,so unremarkable have these one-time wonder drugs become.Modern medicine relies on antibiotics—not just to cure diseases,but to augment the success of surgery,childbirth and cancer treatments.Yet now health authorities are warning,in uncharacteristically apocalyptic terms,that the era of antibiotics is about to end.In some ways,bacteria are continually evolving to resist the drugs.But in the past we’ve always developed new ones that killed them again.Not this time.Infections that once succumbed to everyday antibiotics now require last-resort drugs with unpleasant side effects.Others have become so difficult to treat that they kill some 25,000Europeans yearly.And some bacteria now resist every known antibiotic.Regular readers will know why:New Scientist has reported warnings about this for years.We have misused antibiotics appallingly,handing them out to humans like medicinal candy and feeding them to livestock by the tonne,mostly not for health reasons but to make meat cheaper.Now antibiotic-resistant bacteria can be found all over the world—not just in medical facilities,but everywhere from muddy puddles in India to the snows of Antarctica(南极洲).How did we reach this point without viable successors to today’s increasingly ineffectual drugs? The answer lies not in evolution but economics.Over the past20years,nearly every major pharmaceutical company has abandoned panies must make money,and there isn’t much in short-term drugs that should be used sparingly.So researchers have discovered promising candidates,but can’t reach into the deep pockets needed to develop them.This can be fixed.As we report this week,regulatory agencies,worried medical bodies and Big Pharma are finally hatching ways to remedy this market failure.Delinking profits from the volume of drug sold(by adjusting patent rights,say,or offering prizes for innovation)has worked for other drugs,and should work for antibiotics—although there may be a worryingly long wait before they reach the market.One day,though,these will all to resistance too.Ultimately,we need,evolution-proof cures for bacterial infection:treatments that stop bacteria from causing disease,but don’t otherwise inconvenience the little blighters.When resisting drugs confers no selective advantage,drugs will stop breeding resistance.Researchers have a couple of candidates for such treatment.But they fear regulators will drag their feet over such radical approaches.That,too,can be fixed.We must not neglect development of the sustainable medicine we need,the way we have neglected simple antibiotic R&D.If we do,one day another top doctor will be telling us that the drugs no longer work—and there really will be no help on the way.61.In the first paragraph,the author is tying to_____.A.warn us against the rampant abuse of antibiotics everywhereB.suggest a course of action to reduce antibiotic resistanceC.tell us a time race between humans and bacteriaD.remind us of the universal benefit of antibiotics62.The warning from health authorities implies that_____.A.the pre-antibiotic era will returnB.the antibiotic crisis is about to repeatC.the wonder drugs are a double-edged swordD.the development of new antibiotics is too slow63.The appalling misuse of antibiotics,according to the passage,_____.A.has developed resistant bacteria worldwideB.has been mainly practiced for health reasonsC.has been seldom reported as a warning in the worldD.has been particularly worsened in the developing countries64.The market failure refers to____.A.the inability to develop more powerful antibioticsB.the existing increasingly ineffectual drugs in the marketC.the poor management of the major pharmaceutical companiesD.the deprived investment in developing new classes of antibiotics65.During the presentation of the two solutions,the author carries a tone of_____.A.doubtB.urgencyC.indifferenceD.helplessness Passage TwoThis issue of Science contains announcements for more than100different Gorgon Research Conferences,on topics that range from atomic physics to developmental biology.The brainchild(某人的主意)of Neil Gordon of Johns Hopkins University,these week-long meetings are designed to promote intimate,informal discussions of frontier science.Often confined to fewer than125 attendees,they have traditionally been held in remote places with minimal distractions.Beginning in the early1960s,I attended the summer Nucleic Acids Gordon Conference in rural New Hampshire,sharing austere(简朴的)dorm facilities in a private boy’s school with randomly assigned roommates.As a beginning scientist,I found the question period after each talk especially fascinating,providing valuable insights into the personalities and ways of thinking of many senior scientists whom I had not encountered previously.Back then,there were no cellphones and no internet,and all of the speakers seemed to stay for the entire week.During the long,session-free afternoons,graduate students mingled freely with professors.Many lifelong friendships were begun, and—as Gordon intended—new scientific collaborations began.Leap forward to today,and every scientist can gain immediate access to a vast store of scientific thought and to millions of other scientists via the Internet.Why,nevertheless,do in-person scientific meetings remain so valuable for a life in science?Part of the answer is that science works best when there is a deep mutual trust and understanding between the collaborators,which is hard to develop from a distance.But most important is the critical role that face-to-face scientific meetings play in stimulating a random collision of ideas and approaches.The best science occurs when someone combines the knowledge gained by other scientists in non-obvious ways to create a new understanding of how the world works.A successful scientist needs to deeply believe,whatever the problem being tackled,that there is always a better way to approach that problem than the path currently being taken.The scientist is then constantly on the alert for new paths to take in his or her work,which is essential for makingbreakthroughs.Thus,as much as possible,scientific meetings should be designed to expose the attendees to ways of thinking and techniques that are different from the ones that they already know.66.Assembled at Gordon Research Conference are those who____.A.are physicists and biologistsB.just start doing their sciencesC.stay in the forefront of scienceD.are accomplished senior scientists67.Speaking of the summer Nucleic Acids Gordon Conference,the author thinks highly of____.A.the personalities of senior scientistsB.the question period after each talkC.the austere facilities aroundD.the week-long duration68.It can be inferred from the author that the value of the in-person scientific conference_____.A.does not change with timesB.can be explored online exclusivelyC.lies in exchanging the advances in lie scienceD.is questioned in establishing a vast store of ideas69.The author believes that the face-to-face scientific conferences can help the attendeesbetter_____.A.understand what making a breakthrough means to themB.expose themselves to novel ideas and new approachesC.foster the passion for doing scienceD.tackle the same problem in science70.What would the author most probably talk about in the following paragraphs?A.How to explore scientific collaborations.B.How to make scientific breakthroughs.C.How to design scientific meetings.D.How to think like a genius.Passage ThreeBack in1896,the Swedish scientist Svante Arrhenius realized that by burning coal we were adding carbon dioxide to the air,and that this would warm the Earth.But he mentioned the issue only in passing(顺便地),for his calculations suggested it would not become a problem for thousands of years.Others thought that the oceans would soak up any extra CO2,so there was nothing much to worry about.That this latter argument has persisted to this day in some quarters highlights our species’propensity(倾向)to underestimate the scale of our impact on the planet.Even the Earth’s vast oceans cannot suck up CO2as quickly as we can produce it,and we now know the stored CO2is acidifying the oceans,a problem in itself.Now a handful of researchers are warning that energy sources we normally think of as innocuous could affect the planet’s climate too.If we start to extract immense amounts of power from the wind,for instance,it will have an impact on how warmth and water move around the planet,and thus on temperatures and rainfall.Just to be clear,no one is suggesting we should stop building wind farms on the basis of this risk.Aside from the huge uncertainties about the climatic effects of extracting power from the wind,our present and near-term usage is far too tiny to make any difference.For the moment,any negative consequences on the climate are massively outweighed by the effects of pumping out even more CO2.That poses by far the greater environmental threat;weaning ourselves off fossil fuels should remain the priority.Even so,now it is the time to start thinking about the long-term effects of the alternative energy sources we are turning to.Those who have already started to look at these issues report weary, indifferent or even hostile reactions to their work.That’s understandable,but disappointing.These effects may be inconsequential,in which case all that will have been wasted is some research time that may well yield interesting insights anyway. Or they may turn out to be sharply negative,in which case the more notice we have,the better.It would be unfortunate to put it mildly,to spend countless trillions replacing fossil-fuel energy infrastructure(基础建设)only to discover that its successor(替代物)is also more damaging than it need be.These climatic effects may even be beneficial.The first,tentative models suggest that extracting large amounts of energy from high-altitude jet streams would cool the planet, counteracting the effects of rising greenhouse gases.It might even be possible to build an energy infrastructure that gives us a degree of control over the weather:turning off wind turbines here, capturing more of the sun’s energy there.We may also need to rethink our long-term research priorities.The sun is ultimately the only source of energy that doesn’t end up altering the planet’s energy balance.So the best bet might be invest heavily in improving solar technology and energy storage—rather than in efforts to harness, say,nuclear fusion.For the moment,all of this remains supposition(推测).But our species has a tendency to myopia.We have nothing to lose,and everything to gain by taking the long view for a change.71.In the first two paragraphs,the author is trying to draw our attention to____.A.the escalating scale of the global warmingB.the division of scientists over the issue of global warmingC.reasons for us to worry about extra CO2for the oceansD.the human tendency to underestimate the harmful effects on the planet72.The author’s illustration of wind-power extraction reflects____.A.the priority of protecting the environmentB.the same human propensity as mentioned previouslyC.the best strategy of reducing the environmental threatD.the definite huge uncertainties about the climatic effects73.The author argues that it would be unfortunate to replace fossil fuels only to find out that____.A.the successors are also damagingB.the countless trillions spent are wastedC.the alternative energy sources don’t workD.the research invites indifferent or even hostile reactions74.According to the author,the best strategy is____.A.to counteract the effects of rising greenhouse gasesB.to develop a degree of control over the weatherC.to extract large amounts of energy from windD.to explore solar energy and its storage75.It can be concluded from the passage that we need to take the long view on____.A.human existence on the planetB.humanity’s energy suppliesC.our environmental threatsD.our tendency to myopiaPassage FourOptical illusions are like magic,thrilling us because of their capacity to reveal the fallibility of our senses But there’s more to them than that,according to Dr.Beau Lotto,who is wowing the scientific world with work that crosses the boundaries of art,neurology,natural history and philosophy.What they reveal,he says,is that the whole world is the creation of our brain.What we see, what we hear,feel and what we think we know is not a photographic reflection of the word,but an instantaneous unthinking calculation as to what is the most useful way of seeing the world.It’s a best guess based on the past experience of the individual,a long evolutionary past that has shaped the structure of our brains.The world is literally shaped by our pasts.Dr.Lotto,40,an American who is a reader in neuroscience at University College London,has set out to prove it in stunning visual illusions,sculptures and installations,which have been included in art-science exhibitions.He explains his complex ideas from the starting point of visual illusions,which far from revealing how fragile our senses are show how remarkably robust they are at providing a picture of the world that serves a purpose to us.For centuries,artists and scientists have noted that a grey dot looks lighter against a dark background than being against a light background.The conventional belief was that it was because of some way the brain and eye is intrinsically wired.But Dr.Lotto believes it’s a learnt response;in other words,we see the world not as it is but as it is useful to us.“Context is everything,because our brains have evolved to constantly re-define normality,”says Dr.Lotto.“What we see is defined by our own experiences of the past,but also by what the human race has experienced through its history.”This is illustrated by the fact that different cultures and communities have different viewpoints of the world,conditioned over generations.For example,Japanese people have a famous inability to distinguish between the“R”and the“L”sound.This arises because in Japanese the sounds are totally interchangeable.“Differentiating between them has never been useful,so the brain has never learnt to do it.It’s not just that Japanese people find it hard to tell the difference.They literally cannot hear the difference.”Dr.Lotto’s experiments are grounding more and more hypotheses in hard science.“Yes,mywork is idea-driven,”he says.“But lots of research,such as MRI brain scanning,is technique-driven.I don’t believe you can understand the brain by taking it out of its natural environment and looking at it in a laboratory.You have to look at what it evolved to do,and look at it in relationship to its ecology.”76.What does the word“them”in the first paragraph refer to?A.Human senses.B.The fallibility of senses.C.Revealing capacity.D.Optical illusions.77.According to the passage,what is known about Dr.Beau Lotto?A.Though he is a neuroscientist,he has shocked the scientific world with his extensiveresearch in art,neurology,natural history and philosophy.B.Dr.Lotto is a professor at University College Landon who is specialized in a number ofdisciplines such as art,neurology,natural history and philosophy.C.Dr.Lotto has been attempting to exhibit his creative productions in art-science exhibitionsin the hope of proving his idea on optical illusions.D.Dr.Lotto has set out to create visual illusions,sculptures and installations which wellcombined the knowledge of art,neurology,natural history and philosophy.78.Which of the following statements can be inferred from Dr.Lotto’s study?A.People should believe their brains rather than their eyes as the world,to a great measure,iscreated and shaped by human brain.B.People should never believe their senses for what they see,hear,feel,and the truth may becontrary to the photographic image of the world.C.People should never believe their eyes for what they see are only accidental and temporaryforms of the world,which varies in accordance with contexts.D.People should be aware that their eyes can play tricks on them as what they see is actuallycreated by their brains which are shaped by their past experiences.79.According to Dr.Lotto,what is the reason for the fact that a grey dot looks lighter against adark background than being against a light background?A.It is a fact that the dot emerged to be lighter against a dark background than being against alight one.B.Human senses are remarkably robust at providing a picture of the world that serves apurpose to us through what they have learnt from past experiences.C.It is because of some way the brain and eye is intrinsically wired.D.Because the context in which the little dot placed has changed to be lighter.80.Which of the following statements is true about the research in neuroscience?A.Investigation on the brain involves scrutinizing a network in which both environment andthe brain itself function together.B.Both idea-driven and technique-driven are popular research methods in research study inneuroscience.C.People cannot carry out research study on brain in laboratory where it is isolated fromhuman body.D.Brain can be investigated in isolation with other faculties and organs as long as the researchis carried out in proper natural context.Passage FiveThe biggest thing in operating rooms these days is a million-dollar,multi-armed robot named da Vinci,used in nearly400,000surgeries nationwide last year—triple the number just four years earlier.But now the high-tech helper is under scrutiny over reports of problems,including several deaths that may be linked with it and the high cost of using the robotic system.There also have been a few disturbing,freak incidents:a robotic hand that wouldn’t let go of tissue grasped during surgery and a robotic arm hit-ting a patient in the face as she lay on the operating table.Is it time to curb the robot enthusiasm?Some doctors say yes,concerned that the“wow”factor and heavy marketing have boosted use. They argue that there is not enough robust research showing that robotic surgery is at least as good or better than conventional surgeries.Many U.S.hospitals promote robotic surgery in patient brochures,online and even on highway billboards.Their aim is partly to attract business that helps pay for the costly robot.The da Vinci is used for operations that include removing prostates,gallbladders and wombs, repairing heart valves,shrinking stomachs and transplanting organs.Its use has increased worldwide, but the system is most popular in the United States.For surgeons,who control the robot while sitting at a computer screen rather than standing over the patient,these operations can be less tiring.Plus robot hands don’t shake.Advocates say patients sometimes have less bleeding and often are sent home sooner than with conventional laparoscopic surgeries and operations involving large incisions.But the Food and Drug Administration is looking into a spike in reported problems during robotic surgeries.Earlier this year,the FDA began a survey of surgeons using the robotic system. The agency conducts such surveys of devices routinely,but FDA spokeswoman Synim Rivers said the reason for it now“is the increase in number of reports received”about da Vinci.Reports filed since early last year include at least five deaths.Whether there truly are more problems recently is uncertain.Rivers said she couldn’t quantify the increase and that it may simply reflect more awareness among doctors and hospitals about the need to report problems.Doctors aren’t required to report such things;device makers and hospitals are.Company spokesman Geoff Curtis said Intuitive Surgical has physician-educators and other trainers who teach surgeons how to use the robot.But they don’t train them how to do specific procedures robotically,he said,and that it’s up to hospitals and surgeons to decide“if and when a surgeon is ready to perform robotic cases.”A2010New England Journal of Medicine essay by a doctor and a health policy analyst said surgeons must do at least150procedures to become adept at using the robotic system.But there is no expert consensus on how much training is needed.New Jersey banker Alexis Grattan did a lot of online research before her gallbladder was removed last month at Hackensack University Medical Center.She said the surgeon’s many years of experience with robotic operations was an important factor.She also had heard that the surgeon was among the first to do the robotic operation with just one small incision in the belly button,instead of four cuts in conventional keyhole surgery.81.Why did FDA begin to scrutinize da Vinci?A.The number used in operation has been tripled.B.It is too expensive.C.It is reported to have frequent mechanical breakdown.wsuits increase with death case reports.82.According to some doctors,which of the following is NOT the reason to curb the enthusiasmfor da Vinci?A.The high cost causes unreasonable marketing.B.It is not as good as traditional surgeries.C.It needs more statistics to prove its value.D.It is necessary for doctors to consider some problems.83.What does FDA spokeswoman Synim Rivers mean?A.Doctors and hospitals should be responsible for those problems.B.It is doctors that think da Vinci robots are problematic.C.There are so many problems reports that FDA has to do an enquiry.D.FDA hasn’t finished the previous enquiry about the surgeons who used robots.84.What is correct about training according to the Geoff Curtis?A.A lack of sufficient training on the part of surgeons.B.A lack of sufficient training an the part of company.C.Doctors and hospitals are not sufficiently trained on specific procedures.D.Doctors and hospitals are not sufficiently trained on how to use robots.85.What is the best title for this passage?A.Four Hands Better than Two?B.Too Good to Be TrueC.Smart RobotsD.Who Is the Killer?Passage SixIn a poor,inland,gang-infested part of Los Angeles,there is a clinic for people with type1 diabetes.As part of the country health care system,it serves persons who have fallen through all other safety-net options,the poorest of the poor.Although type2diabetes is rampant in this part of。

2006-2015年首都医科大学考博生理原题及答案(自整理)名词解释:1、all-or-none (2012)细胞产生动作电位的特点是,当刺激强度小于阈刺激时,细胞不产生动作电位,当刺激强度等于或大于阈强度时,细胞即产生动作电位,且幅度不再加大,此种现象称为“全或无”。
即动作电位的大小不随刺激强度的改变而改变。
2、recurrent inhibition (2012)是指某一中枢的神经元兴奋时,其传出冲动沿轴突外传,同时又经轴突侧支去兴奋另一抑制性中间神经元,该抑制性神经元兴奋后,其活动经轴突反过来作用于同一中枢的神经元,抑制原先发动兴奋的神经元及同一中枢的其他神经元。
3、overdrive suppression (2012)当自律细胞在受到高于其固有频率的刺激时,就按外加刺激的频率发生兴奋,称为超速驱动。
在外来的超速驱动停止后,自律细胞不能呈现其固有的自律性活动,需经一段静止期后才逐渐恢复其自律性,这种现象称为超速驱动压抑。
4、renal threshold for glucose (2012)尿中不出现葡萄糖的最高血糖浓度。
OR:近端小管对葡萄糖的吸收有一定限度。
当血糖浓度达180mg/100ml 时,有一部分肾小管对葡萄糖的吸收已达极限,尿中开始出现葡萄糖,此时的血浆葡萄糖浓度称为肾糖阈。
5、transducer function of receptor (2012)各种感受器在功能上的一个共同特点,是能把作用于它们的各种形式的刺激能量转换为传入神经的动作电位,这种能量转换称为感受器的换能作用。
6、basic electrical rhythm (2011,2010,2006)指胃肠平滑肌细胞在静息电位基础上产生缓慢的节律性的自动去极化波,又称慢波。
7、local potential (2011,2009,2007,2006)阈下刺激作用于细胞,引起膜原有的得到电位发生轻微的改变,称为局部电位。

(One theory behind the 1918 version's sudden demise after wreaking so much devastation was that it mutated to a nonlethal form. ) The same branch of research concluded in 2005 that the 1918 flu started in birds before passing to humans. Parsing this animal-human【C1】______could provide clues to【C2】______the next potential superflu, which already has a name: H5N1, also known as avian flu or bird flu. This potential killer also has a number: 59 percent. According to the World Health Organization, nearly three-fifths of the people who【C3】______H5N1 since 2003 died from the virus, which was first reported【C4】______humans in Hong Kong in 1997 before a more serious 【C5】______occurred in Southeast Asia between 2003 and 2004. (It has since spread to Africa and Europe. ) Some researchers argue that those mortality numbers are exaggerated because WHO only 【C6】______cases in which victims are sick enough to go to the hospital for treatment【C7】______compare that to the worldwide mortality rate of the 1918 pandemic; it may have killed roughly50 million people, but that was only 10 percent of the number of people infected, according toa 2006 estimate. H5N1's saving grace — and the only reason we're not running around masked up in public right now — is that the strain doesn't jump from birds to humans, or from humans to humans, easily. There have been just over 600 cases (and 359 deaths) since 2003. But【C8】______its lethality, and the chance it could turn into something far more transmissible, one might expect H5N1 research to be exploding, with labs【C9】______the virus's molecular components to understand how it spreads between animals and【C10】______to humans, and hoping to discover a vaccine that could head off a pandemic.(分数:20.00)(1).【C1】(分数:2.00)A.interactB.interfaceC.connectionD.contamination(2).【C2】(分数:2.00)A.stoppingB.stoppedC.have stoppedD.stop(3).【C3】(分数:2.00)A.contactedB.contractedC.concentratedD.infected(4).【C4】(分数:2.00)A.onB.inC.ofD.with(5).【C5】(分数:2.00)A.breakoutB.take placeC.happenD.outbreak(6).【C6】(分数:2.00)A.accountsB.numbersC.countsD.takes(7).【C7】(分数:2.00)A.MoreoverB.StillC.FurthermoreD.Thereafter(8).【C8】(分数:2.00)A.givenB.givingC.to giveD.speaking of(9).【C9】(分数:2.00)A.parsingB.parsedC.to parseD.having parsed(10).【C10】(分数:2.00)A.presentlyB.potentiallyC.potentlyD.importantly四、PartⅣ Reading Compre(总题数:6,分数:60.00)If you are reading this article, antibiotics have probably saved your life—and not once but several times. A rotten tooth, a knee operation, a brush with pneumonia; any number of minor infections that never turned nasty. You may not remember taking the pills, so unremarkable havethese one-time wonder drugs become. Modern medicine relies on antibiotics — not just to cure diseases, but to augment the success of surgery, childbirth and cancer treatments. Yet now health authorities are warning, in uncharacteristically apocalyptic terms, that the era of antibiotics is about to end. In some ways, bacteria are continually evolving to resist the drugs. But in the past we've always developed new ones that killed them again. Not this time. Infections that once succumbed to everyday antibiotics now require last-resort drugs with unpleasant side effects. Others have become so difficult to treat that they kill some 25, 000 Europeans yearly. And some bacteria now resist every known antibiotic. Regular readers will know why: New Scientist has reported warnings about this for years. We have misused antibiotics appallingly, handing them out to humans like medicinal candy and feeding them to livestock by the tonne, mostly not for health reasons but to make meat cheaper. Now antibiotic-resistant bacteria can be found all over the world — not just in medical facilities, but everywhere from muddy puddles in India to the snows of Antarctica (南极洲) . How did we reach this point without viable successors to today's increasingly ineffectual drugs? The answer lies not in evolution but economics. Over the past 20 years, nearly every major pharmaceutical company has abandoned antibiotics. Companies must make money, and there isn't much in short-term drugs that should be used sparingly. So researchers have discovered promising candidates, but can't reach into the deep pockets needed to develop them. This can be fixed. As we report this week, regulatory agencies, worried medical bodies and Big Pharma are finally hatching ways to remedy this market failure. Delinking profits from the volume of drug sold (by adjusting patent rights, say, or offering prizes for innovation) has worked for other drugs, and should work for antibiotics — although there may be a worryingly long wait before they reach the market. One day, though, these will fall to resistance too. Ultimately, we need, evolution-proof cures for bacterial infection: treatments that stop bacteria from causing disease, but don't otherwise inconvenience the little blighters. When resisting drugs confers no selective advantage, drugs will stop breeding resistance. Researchers have a couple of candidates for such treatment. But they fear regulators will drag their feet over such radical approaches. That, too, can be fixed. We must not neglect development of the sustainable medicine we need, the way we have neglected simple antibiotic R&D. If we do, one day another top doctor will be telling us that the drugs no longer work—and there really will be no help on the way.(分数:10.00)(1).In the first paragraph, the author is trying to______.(分数:2.00)A.warn us against the rampant abuse of antibiotics everywhereB.suggest a course of action to reduce antibiotic resistanceC.tell us a time race between humans and bacteriaD.remind us of the universal benefit of antibiotics(2).The warning from health authorities implies that______.(分数:2.00)A.the pre-antibiotic era will returnB.the antibiotic crisis is about to repeatC.the wonder drugs are a double-edged swordD.the development of new antibiotics is too slow(3).The appalling misuse of antibiotics, according to the passage, ______.(分数:2.00)A.has developed resistant bacteria worldwideB.has been mainly practiced for health reasonsC.has been seldom reported as a warning in the worldD.has been particularly worsened in the developing countries(4).The market failure refers to______.(分数:2.00)A.the inability to develop more powerful antibioticsB.the existing increasingly ineffectual drugs in the marketC.the poor management of the major pharmaceutical companiesD.the deprived investment in developing new classes of antibiotics(5).During the presentation of the two solutions, the author carries a tone of______.(分数:2.00)A.doubtB.urgencyC.indifferenceD.helplessnessWhere one stage of child development has been left out, or not sufficiently experienced, the child may have to go back and capture the experience of it. A good home makes this possible, for example by providing the opportunity for the child to play with a clockwork car or toy railway train up to any age if he still needs to do so. This principle, in fact, underlies all psychological treatment of children in difficulties with their development, and is the basis of work in child clinics. The beginnings of discipline are in the nursery. Even the youngest baby is taught by gradual stages to wait for food, to sleep and wake at regular intervals and so on. If the child feels the world around him is a warm and friendly one, he slowly accepts its rhythm and accustoms himself to conforming to its demands. Learning to wait for things, particularly for food, is a very important element in upbringing, and is achieved successfully only if too great demands are not made before the child can understand them. Every parent watches eagerly the child's acquisition of each new skill—the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feeling of failure and states of anxiety in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural zest for life and his desire to find out new things for himself. Learning together is a fruit source of relationship between children and parents. By playing together, parents learn more about their children and children learn more from their parents. Toys and games which both parents and children can share are an important means of achieving this co-operation. Building-block toys, jigsaw puzzles and crossword are good examples. Parents vary greatly in their degree of strictness or indulgence towards their children. Some may be especially strict in money matters, others are severe over times of coming home at night, punctuality for meals or personal cleanliness. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child's own happiness and well-being.(分数:10.00)(1).The principle underlying all treatment of developmental difficulties in children______.(分数:2.00)A.is to send them to clinicsB.offers recapture of earlier experiencesC.is in the provision of clockwork toys and trainsD.is to capture them before they are sufficiently experienced(2).The child in the nursery______.(分数:2.00)A.quickly learns to wait for foodB.doesn't initially sleep and wake at regular intervalsC.always accepts the rhythm of the world around themD.always feels the world around him is warm and friendly(3).The encouragement of children to achieve new skills______.(分数:2.00)A.can never be taken too farB.should be left to school teachersC.will always assist their developmentD.should be balanced between two extremes(4).Jigsaw puzzles are______.(分数:2.00)A.too difficult for childrenB.a kind of building-block toyC.not very entertaining for adultsD.suitable exercises for parent-child cooperation(5).Parental controls and discipline______.(分数:2.00)A.serve a dual purposeB.should be avoided as much as possibleC.reflect the values of the communityD.are designed to promote the child's happinessFor 150 years scientists have tried to determine the solar constant, the amount of solar energy that reaches the Earth. Yet, even in the most cloud-free regions of the planet, the solar constant cannot be measured precisely. Gas molecules and dust particles in the atmosphere absorb and scatter sunlight and prevent some wavelengths of the light from ever reaching the ground. With the advent of satellites, however, scientists have finally been able to measure the Sun's output without being impeded by the Earth's atmosphere. Solar Max, a satellite from the National Aeronautics and Space Administration (NASA), has been measuring the Sun's output since February 1980. Although a malfunction in the satellite's control system limited its observation for a few years, the satellite was repaired in orbit by astronauts from the space shuffle in 1984. Max's observations indicate that the solar constant is not really constant after all. The satellite's instruments have detected frequent, small variations in the Sun's energy output, generally amounting to no more than 0. 05 percent of the Sun's mean energy output and lasting from a few days to a few weeks. Scientists believe these fluctuations coincide with the appearance and disappearance of large groups of sunspots on the Sun's disk. Sunspots are relatively dark regions on the Sun's surface that have strong magnetic fields and a temperature about 2, 000 degrees Fahrenheit cooler than the rest of the Sun's surface. Particularly large fluctuations in the solar constant have coincided with sightings of large sunspot groups. In 1980, for example, Solar Max's instruments registered a 0. 3 percent drop in the solar energy reaching the Earth. At that time a sunspot group covered about 0. 6 percent of the solar disk, an area 20 times larger than the Earth's surface. Long-term variations in the solar constant are more difficult to determine. Although Solar Max's data have indicated a slow and steady decline in the Sun's output. Some scientists have thought that the satellite's aging detectors might have become less sensitive over the years, thus falsely indicating a drop in the solar constant. This possibility was dismissed, however, by comparing solar Max's observations with data from a similar instrument operating on NASA's Nimbus 7 weather satellite since 1978.(分数:10.00)(1).According to the passage, scientists believe variations in the solar constant are related to______.(分数:2.00)A.sunspot activityB.unusual weather patternsC.increased levels of dustD.fluctuations in the Earth's temperature(2).Why is it not possible to measure the solar constant accurately without a satellite?(分数:2.00)A.The Earth is too far from the Sun.B.Some areas on Earth receive more solar energy than others.C.There is not enough sunlight during the day.D.The Earth's atmosphere interferes with the sunlight.(3).Why did scientists think that Solar Max might be giving unreliable information?(分数:2.00)A.Solar Max did not work for the first few years.B.Solar Max's instruments were getting old.C.The space shuttle could not fix Solar Max's instruments.D.Nimbus 7 interfered with Solar Max's detectors.(4).The attempt to describe the solar constant can best be described as______.(分数:2.00)A.an ongoing research effortB.a question that can never be answeredC.an issue that has been resolvedD.historically interesting, but irrelevant to contemporary concerns(5).What does this passage mainly discuss?(分数:2.00)A.The components of the Earth's atmosphere,B.The launching of a weather satellite.C.The measurement of variations in the solar constant.D.The interaction of sunlight and air pollution.Optical illusions are like magic, thrilling us because of their capacity to reveal the fallibility of our senses. But there's more to them than that, according to Dr. Beau Lotto, who is wowing the scientific world with work that crosses the boundaries of art, neurology, natural history and philosophy. What they reveal, he says, is that the whole world is the creation of our brain. What we see, what we hear, feel and what we think we know is not a photographic reflection of the world, but an instantaneous unthinking calculation as to what is the most useful way of seeing the world. It's a best guess based on the past experience of the individual, a long evolutionary past that has shaped the structure of our brains. The world is literally shaped by our pasts. Dr. Lotto, 40, an American who is a reader in neuroscience at University College London, has set out to prove it in stunning visual illusions, sculptures and installations, which have been included in art-science exhibitions. He explains his complex ideas from the starting point of visual illusions, which far from revealing how fragile our senses are show how remarkably robust they are at providing a picture of the world that serves a purpose to us. For centuries, artists and scientists have noted that a grey dot looks lighter against a dark background than being against a light background. The conventional belief was that it was because of some way the brain and eye is intrinsically wired. But Dr. Lotto believes it's a learnt response; in other words, we see the world not as it is but as it is useful to us. "Context is everything, because our brains have evolved to constantly re-define normality, " says Dr. Lotto. "What we see is defined by our own experiences of the past, but also by what the human race has experienced through its history, " This is illustrated by the fact that different cultures and communities have different viewpoints of the world, conditioned over generations. For example, Japanese people have a famous inability to distinguish between the "R" and the "L" sound. This arises because in Japanese the sounds are totally interchangeable. "Differentiating between them has never been useful, so the brain has never learnt to do it. It's not just that Japanese people find it hard to tell the difference. They literally cannot hear the difference. " Dr. Lotto's experiments are grounding more and more hypotheses in hard science. "Yes, my work is idea-driven, " he says. "But lots of research, such as MRI brain scanning, is technique-driven. I don't believe you can understand the brain by taking it out of its natural environment and looking at it in a laboratory. You have to look at what it evolved to do, and look at it in relationship to its ecology. "(分数:10.00)(1).What does the word "them" in the first paragraph refer to?(分数:2.00)A.Human senses.B.The fallibility of senses.C.Revealing capacity.D.Optical illusions.(2).According to the passage, what is known about Dr. Beau Lotto?(分数:2.00)A.Though he is a neuroscientist, he has shocked the scientific world with his extensive research in art, neurology, natural history and philosophy.B.Dr. Lotto is a professor at University College London who is specialized in a number of disciplines such as art, neurology, natural history and philosophy.C.Dr. Lotto has been attempting to exhibit his creative productions in art-science exhibitions in the hope of proving his idea on optical illusions.D.Dr. Lotto has set out to create visual illusions, sculptures and installations which well combined the knowledge of art, neurology, natural history and philosophy.(3).Which of the following statements can be inferred from Dr. Lotto's study?(分数:2.00)A.People should believe their brains rather than their eyes as the world, to a great measure, is created and shaped by human brain.B.People should never believe their senses for what they see, hear, feel, and the truth may be contrary to the photographic image of the world.C.People should never believe their eyes for what they see are only accidental and temporary forms of the world, which varies in accordance with contexts.D.People should be aware that their eyes can play tricks on them as what they see is actually created by their brains which are shaped by their past experiences.(4).According to Dr. Lotto, what is the reason for the fact that a grey dot looks lighter againsta dark background than being against a light background?(分数:2.00)A.It is a fact that the dot emerged to be lighter against a dark background than being against a light one.B.Human senses are remarkably robust at providing a picture of the world that serves a purpose to us through what they have learnt from past experiences.C.It is because of some way the brain and eye is intrinsically wired.D.Because the context in which the little dot placed has changed to be lighter.(5).Which of the following statements is true about the research in neuroscience?(分数:2.00)A.Investigation on the brain involves scrutinizing a network in which both environment and the brain itself function together.B.Both idea-driven and technique-driven are popular research methods in research study in neuroscience.C.People cannot carry out research study on brain in laboratory where it is isolated from human body.D.Brain can be investigated in isolation with other faculties and organs as long as the research is carried out in proper natural context.The biggest thing in operating rooms these days is a million-dollar, multi-armed robot named da Vinci, used in nearly 400, 000 surgeries nationwide last year—triple the number just four years earlier. But now the high-tech helper is under scrutiny over reports of problems, including several deaths that may be linked with it and the high cost of using the robotic system. There also have been a few disturbing, freak incidents: a robotic hand that wouldn't let go of tissue grasped during surgery and a robotic arm hitting a patient in the face as she lay on the operating table. Is it time to curb the robot enthusiasm? Some doctors say yes, concerned that the "wow" factor and heavy marketing have boosted use. They argue that there is not enough robust research showing that robotic surgery is at least as good or better than conventional surgeries. Many U. S. hospitals promote robotic surgery in patient brochures, online and even on highway billboards. Their aim is partly to attract business that helps pay for the costly robot. The da Vinci is used for operations that include removing prostates, gallbladders and wombs, repairing heart valves, shrinking stomachs and transplanting organs. Its use has increased worldwide, but the system is most popular in the United States. For surgeons, who control the robot while sitting at a computer screen rather than standing over the patient, these operations can be less tiring. Plus robothands don't shake. Advocates say patients sometimes have less bleeding and often are sent home sooner than with conventional laparoscopic surgeries and operations involving large incisions. But the Food and Drug Administration is looking into a spike in reported problems during robotic surgeries. Earlier this year, the FDA began a survey of surgeons using the robotic system. The agency conducts such surveys of devices routinely, but FDA spokeswoman Synim Rivers said the reason for it now "is the increase in number of reports received" about da Vinci. Reports filed since early last year include at least five deaths. Whether there truly are more problems recently is uncertain. Rivers said she couldn't quantify the increase and that it may simply reflect more awareness among doctors and hospitals about the need to report problems. Doctors aren't required to report such things; device makers and hospitals are. Company spokesman Geoff Curtis said Intuitive Surgical has physician-educators and other trainers who teach surgeons how to use the robot. But they don't train them how to do specific procedures robotically, he said, and that it's up to hospitals and surgeons to decide "if and when a surgeon is ready to perform robotic cases. " A 2010 New England Journal of Medicine essay by a doctor and a health policy analyst said surgeons must do at least 150 procedures to become adept at using the robotic system. But there is no expert consensus on how much training is needed. New Jersey banker Alexis Grattan did a lot of online research before her gallbladder was removed last month at Hackensack University Medical Center. She said the surgeon's many years of experience with robotic operations was an important factor. She also had heard that the surgeon was among the first to do the robotic operation with just one small incision in the belly button, instead of four cuts in conventional keyhole surgery.(分数:10.00)(1).Why did FDA begin to scrutinize da Vinci?(分数:2.00)A.The number used in operation has been tripled.B.It is too expensive.C.It is reported to have frequent mechanical breakdown.wsuits increase with death case reports.(2).According to some doctors, which of the following is NOT the reason to curb the enthusiasm for da Vinci?(分数:2.00)A.The high cost causes unreasonable marketing.B.It is not as good as traditional surgeries.C.It needs more statistics to prove its value.D.It is necessary for doctors to consider some problems.(3).What does FDA spokeswoman Synim Rivers mean?(分数:2.00)A.Doctors and hospitals should be responsible for those problems.B.It is doctors that think da Vinci robots are problematic.C.There are so many problems reports that FDA has to do an enquiry.D.FDA hasn't finished the previous enquiry about the surgeons who used robots.(4).What is correct about training according to the Geoff Curtis?(分数:2.00)A.A lack of sufficient training on the part of surgeons.B.A lack of sufficient training on the part of company.C.Doctors and hospitals are not sufficiently trained on specific procedures.D.Doctors and hospitals are not sufficiently trained on how to used robots.(5).What is the best title for this passage?(分数:2.00)A.Four Hands Better than Two?B.Too Good to Be TrueC.Smart RobotsD.Who Is the Killer?Despite Denmark's manifest virtues, Danes never talk about how proud they are to be Danes. This would sound weird in Danish. When Danes talk to foreigners about Denmark, they always begin by。

This is one of the expected conclusions of an official government report to be published this week. The report is expected to call for the mobile phone industry to refrain from promoting phone use by children, and to start labeling phones with data on the amount of radiation they emit. The Independent Expert Group on Mobile Phones, chaired by former government chief scientist William Stewart, has spent eight months reviewing existing scientific evidence on all aspects of the health effects of using mobile phones. Its report is believed to conclude that because we don’t fully understand the nonthermal effects of radiation on human tissue, the government should adopt a precautionary approach, particularly in relation to children.There is currently no evidence that mobile phones harm users or people living near transmitter masts. But some studies show that cell-phones operating at radiation levels within current safety limits do have some sort of biological effect on the brain.to environmental insults,” he says,“So if phones did prove to be hazardous——which they haven’t yet ——it would be sensible.”In 1998, Tattersall showed that radiation levels similar to those emitted by mobile phones could alter signals from brain cells in slices of rat brain, “What we’ve found is an effect, but we don’t know if it’s hazardous,” he says.Alan Preece of the University of Bristol, who found last year that microwaves increase reaction times in test subjects, agreed that children’s exposure would be greater. “There’s a lot less tissue in the way, and the skill is thinner, so children’s heads are considerably closer,” he says.Stewart’s report is likely to recommend that the current British safety standards on energy emissions from cell-phones should be cut to the level recommended by the International Commission on Non-Ionizing Radiation Protection, which is one-fifth of the current British limit. “The extra safety factor of five is somewhat arbitrary,” s ays Michael Clark of the National Radiological Protection Board. “But we accept that it’s difficult for the UK to have different standards from an international body.”61. Just because it has not been confirmed yet whether mobile phone emissions can harm humantissue, according to the government report, does not mean that .A. the government should prohibit children from using cell-phonesB. we should put down the phone for the sake of safetyC. the industry can have a right to promote phone useD. children are safe using cell-phones62. Tattersall argues that it is wise to refrain mobile phone use by children in termsof .A. their neural developmentB. their ill-designed cell-phonesC. the frequency of their irrational useD. their ignorance of its possible health effects63. On the issue in question, Preece .A. does not agree with TattersallB. tries to remove the obstacles in the wayC. asks for further investigationD. would stand by Stewart64. What is worrisome at present is that the UK .A. is going to turn deaf ears to the voice of Stesart’s planB. finds it difficult to cut the current safety standards on phone useC. maintains different standards on safety limit from the international onesD. does not even impose safety limit on the mobile phones’ energy emissions65.Which of the following can bi the best candidate for the title of the passageA . Brain Wave B. For Adults OnlyC. Catch Them YoungD. The Answer in the AirPassage TwoAdvances in cosmetic dentistry and plastic surgery have made it possible to correct facial birth defects, repair damaged teeth and tissue, and prevent or greatly delay the onset of tooth decay and gum disease. As a result, more people smile more often and more openly today than ever in the past, and we can expect more smiles in the future.middle-class family members in formal portraits and domestic scenes appear to have their mouths firmly closed. Soldiers in battle, children at play, beggars, old people, and especially villains may have their mouths open; but their smiles are seldom attractive, and more often suggest strain or violence than joy.Smiles convey a wide range of meanings in different eras and cultures, says art historian Angus Trumble, currently curator(馆长)of Yale University’s Center for British Art, in his book A Brief History of the Smile. Compare, for instance, the varying impressions made by the shy dimples(酒窝)of Leonardo’s Mona Lisa; the rosy-cheeked, mustachioed Laughing Cavalier of Frans Hals; and the”Smiley Face”logo perfected(though not invented)in 1963 by American graphic artist Harvey .In some non-Western cultures, Trumble notes, even a warm, open smile does not necessarily indicate pleasure or agreement. It can simply be a polite mask to cover emotions considered too rude or shocking to bi openly displayed.Subtle differences in muscle movement can convey enormous differences in emotion, from the tranquility of bronze Buddhas, to the erotic bliss of couples entwined in stone on Hindu temples,to the fierce smirk(假笑)of a guardian demon at the entrance to a Chinese tomb.Trumble expects the impact of Western medicine and mass media to further increase the pressure on people to grin broadly and laugh openly in public.”Faint smiles are increasingly thought of in scientific and psychological circles as something that falls short of the true smile ,”and therefore suggest insincerity or lack of enthusiasm, he says.With tattooing, boby piercing, and permanent cosmetics already well established as fashion trends, one can imagine tomorrow’s beauty shops adding plastic surgeons and dentists to their staffs. These comer-store cosmeticians would offer style makeovers to reshape our lips, teeth, and jawlines to mimic the signature smile of one’s favorite celebrity.What can you say to that except” Have a nice day”66. Had it not been for cosmetic advances, as inferred from the passage, .A . people would not have been as happy as they are todayB. the rate of facial birth defect would not have declinedC . there would not have been many more open smilesD. we would not have seen smiling faces in public67. According to the passage, it seems that whether there is a smile or not in the portraits orpictures is decided by .A. one’s internal sense of the external worldB . one’s identity or social positionC . one’s times of existenceD . All of the above68. Trumble’s study on smiles shows that .A. an open smile can serve as a cover-upB . the famous portraits radiate varying smilesC. even the human muscles can arouse varying emotionsD. smiles can represent misinterpretations of different eras and cultures69. What Trumble expects to see is .A. the increasing tendency of broad grins and open smiles in publicB . further impact of Western medicine upon non-Western culturesC. a wider range of meanings to be conveyed by smilesD. more of sincerity and enthusiasm in public70 . At the end of the passage, the author implicates .C . future changes in life styleD . the future of smilesPassage ThreeAdolf Hitler survived an assassination attempt in 1944 with the lamp of penicillin made by the Allies, a microbiologist in the UK claims. If the Nazi leader had died from bacterial infection ofhis many wounds, the Second World War might have been over a year earlier, saving millions of lives, says Milton Wainwright of the University of Sheffield, a noted historian of microbiology.In a paper to be published soon in Perspectives in Biology and Medicine, Wainwright reveals first-hand evidence that Hitler was treated with penicillin by his personal doctor, Theo Morrell, following an assassination attempt in which a bomb in a suitcase exploded next to Hitler’s desk. Hitler was badly hurt, fleeing the scene with his hair and trousers on fire, a badly bleeding arm and countless wooden splinter wounds from the oak table that probably saved his life.Wainwright found confirmation that Morrell gave Hitler antibiotics as a precaution in a recent translation of Morrell’s own diary. “I happened to be reading it for interest when the word penicillin jumped out at me,” he says. He then set about trying to establish where Morrell might have got the drug.At the time, penicillin was available only to the Allies. German and Czechoslovakian teams had tried without much success to make it, Wainwright says, but the small quantities that weresays Wainwright. available were weak and impure. “It’s generally accepted that it was no good,”He reasons that Morrell would only have risked giving Hitler penicillin to prevent infectionsif he were confident that the antibiotic would cure, not kill the German premier. “My research shows that Morrell, in a very dodgy(危险的) position as Hitler’s doctor, would only have used pure stuff.” And the only reliable penicillin was that made by the Allies. So where did Morrell getitWainwright’s investigations revealed that Allied airmen carried penicillin, so the Germans may have confiscated some from prisoners of war. The other more likely source is from neutral countries such Spain, which received penicillin from Allied countries for humanitarian purposes, perhaps for treating sick children.have proof the Allies were sending it to these countries,” says Wainwright. “I’m saying “Ithis would have got through in diplomatic bags, reaching Hitler’s doctor and the higher echelons(阶层)of the Nazi party. So this was almost certainly pure, Allied penicillin.”“We can never be certain it saved Hitler’s life,” says Wainwright. But he notes that one of Hitler’s henchmen(死党),Reinhard Heydrich, died from blood poisoning after surviving acar-bomb assassination attempt. “Hair from his seat went into his wounds and gave him septicemia,” says Wainwright. Morrell may have been anxious to ensure that Hitler avoided the same fate.71. According to Wainwright, Adolf Hitler .A. might have used biological weapons in the warB. could not have committed suicide as confirmedC. could have died of bacterial infectionD. might have survived a bacterial plague72.

Instead, all you have to do is stand still for 30 seconds while the machine measures your body fat. It could then tell you exactly where you could do with losing afew pounds and even advise you on exercises for your problem areas. If the body fat scanner turns out to be accurate enough, its makers hope it could one day help doctors spot disease.The scanner works by simultaneously building up an accurate 3D image of the body, while measuring the body’s effect on an electromagnetic field. Combining the two measurements allows the researchers to work out the distribution of fat and water within. Neither method is new on itsown, says Henri Tapp, at the Institute of Food Research in Norwich in the UK. “The smart thing is that we’ve put them in one machine.”And it’s not just for gym users. The body fat scanner could be used to study fat deposition as children develop, while patients recover from injury, or during pregnancy. And since it uses radio waves rather than X-rays, Tapp’s device is safe to use repeatedly.Body shape is known to be a risk indicator for heart disease and diabetes. So accurately quantifying fat distribution could help doctors suggest preventive measures to patients before problems arise. At the moment, doctors estimate fat content from knowing body volume and water content. To a good approximation, says Tapp, anything that isn’t fat is water. The amount of water in the body is often measured by giving the subject a drink of water that contains a radioactive tracer. The level of tracer in the patient's urine after three hours reveals the total water volume.To find out a body’s volume, subjects are weighed while totally submerged in water, and thisis subtracted from their normal weight to give the weight of water displaced, and hence the subject’s volume. But it is scarcely practical for seriously ill people.There are other ways to directly measure body fat, such as passing a minuscule current between the wrists and feet. The overall fat content can then be estimated from the body’s resistance. But this method doesn’t take body shape into account ——so a subject with particularly skinny legs might register a higher fat content than the true value. That’s because skinny legs—with a lower cross-sectional area——will present higher resistance to current. So the machine thinks the water content of the body is lower——rating the subject as fatter. Also, the system can only give an overall measurement of fat.Tapp’s method uses similar calculations, but is more sophisticated because it tells you where you are piling on the pounds.76. The new machine is designed .A. to picture the body’s hidden fatB. to identify those at risk for obesityC. to help clinically treat specific casesD. to measure accurately risky obesity-related effects77. The beauty of the device, according to Tapp, is that .A. it performs a dual functionB. it is of great accuracy in measurementC. it has significant implications in clinical practiceD. it contributes to the evolution of human anatomy78.Which of the following, according to the passage, does the machine have the potential tospareA. A minuscule current.B. A radioactive tracer.C. A water tank.D. All of the above.79.In comparison with the techniques mentioned in the passage, the body fat scanner .A. quickens the pace of the patient’s rehabilitationB. is highly appreciated for its safetyC. features its measuring precisionD. is easy to operate in the clinic80.For scanning, all the subject has to do is .A. take up a form of workout in the gymB. turn round the body fat scannerC. lie on the electromagnetic fieldD. sand in the systemPassage FiveThere is currently abroad a new wave of appreciation for breadth of knowledge. Curricula at universalities and colleges and programs in federal agencies extol(赞扬) the virtues of a broad education. For scientists who work in specialized jobs, it is a pleasure to escape in our spare timeto read broadly in fields distant from our own. Some of us have made interdisciplinary study our occupation, which is no surprise, because much of the intellectual action in our society today liesat the interfaces between traditional disciplines. Environmental science is a good example, because it frequently requires us to be conversant in several different sciences and even some unscientific fields.Experiencing this breadth of knowledge is stimulating, but so is delving deeply into a subject. Both are wonderful experiences that are complementary practical and aesthetic(美学的)ways. They are like viewing the marvelous sculpture of knowledge in two different ways. Look at the sculpture from one perspective and you see the piece in its entirety, how its components connect to give it form, balance, and symmetry. From another viewpoint you see its detail, depth, and mass. There is no need to choose between these two perspectives in art. To do so would subtract fromthe totality of the figure.So it is with science. Sometimes we gaze through a subject and are reluctant to stop for too much detail. As chemists, we are fascinated by computer sciences or molecular genetics, but not enough to become an expert. Or we may be interested in an analytical technique but not enough to stay at its cutting edge. At other times, we become immersed in the detail of a subject and see its beauty in an entirely different way than when we browse. It is as if we penetrate the surface of the sculpture and pass through the crystal structure to the molecular level where the code for the entire structure is revealed.Unfortunately, in our zeal for breadth or depth, we often feel that it is necessary to diminishthe value of the other. Specialists are sometimes ridiculed with names such as “nerd”or “technocrats”, generalists are often criticized for being too “soft” or knowing too little about any one thing. Both are ludicrous(可笑的) accusations that deny a part of the reality of。
