病理生理学简答题(考博)

1 .简述各种原因使血管内皮细胞损伤引起DIC 的机制。

缺氧、酸中毒、抗原一抗体复合物、严重感染、内毒素等原因,可损伤血管内皮细胞,内皮细胞受损可产生如下作用:(1)促凝作用增强,主要是因为:①损伤的血管内皮细胞可释放TF ,启动凝血系统,促凝作用增强;②带负电荷的胶原暴露后可通过F Ⅻa 激活内源性凝血系统。

(2)血管内皮细胞的抗凝作用降低。

主要表现在:①TM /PC 和HS /AT Ⅲ系统功能降低;②产生的TFPI 减少。

(3) 血管内皮细胞的纤溶活性降低,表现为:血管内皮细胞产生tPA 减少,而PAI-1 产生增多。

(4) 血管内皮损伤使NO 、PGI 2 、ADP 酶等产生减少,抑制血小板粘附、聚集的功能降低,促进血小板粘附、聚集。

(5) 胶原的暴露可使F Ⅻ激活,可进一步激活激肽系统、补体系统等。

激肽和补体产物(C 3a 、C 5a ) 也可促进DIC 的发生2 .简述严重感染导致DIC 的机制。

①内毒素及严重感染时产生的TNFα、IL-l 等细胞因子作用于内皮细胞可使TF 表达增加;而同时又可使内皮细胞上的TM、HS的表达明显减少,这样一来,血管内皮细胞表面的原抗凝状态变为促凝状态;②内毒素可损伤血管内皮细胞,暴露胶原,使血小板粘附、活化、聚集并释放ADP、TXA 2 等,进一步促进血小板的活化、聚集,促进微血栓的形成。

此外,内毒素也可通过激活PAF,促进血小板的活化、聚集;③严重感染时释放的细胞因子可激活白细胞,激活的白细胞可释放蛋白酶和活性氧等炎症介质,损伤血管内皮细胞,并使其抗凝功能降低;④产生的细胞因子可使血管内皮细胞产生tPA 减少,而PAI-1 产生增多。

使生成血栓的溶解障碍,也与微血栓的形成有关。

总之,严重感染时,由于机体凝血功能增强,抗凝及纤溶功能不足,血小板、白细胞激活等,使凝血与抗凝功能平衡紊乱,促进微血栓的形成,导致DIC的发生、发展。

4 .简述引起APC 抵抗的原因及其机制。

Their study was 54 by the NIH and the university.In the study, CAD was applied to 32 low-dose CT scanning with a total of 50 lung nodules, 38 of which were biopsy-confirmed lung cancer that were not found during initial clinical exam. 55 the 38 missed cancers,15 were the result of interpretation error (identifying an image but 56 it as non cancerous) and 23 57 observational error(not identifying the cancerous image).CAD found 32 of the 38 previously missed cancers (84% sensitivity), with false-positive 58 of 1.6 per section.Although CAD improved detection of lung ca ncer, it won’t replace radiologists, said Sgmuel G Armato, PhD, lead author of the study.” The computer is not perfect,”Armato said.” It will miss some cancers and call some things cancer that 59 .

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 OneWhen Tony Wagner, the Harvard education specialist, describes his job today, he says he’s“a translator between two hostile tribes”—the education world and the business world, the people who teach our kids and the people who give them jobs. Wagner’s ar gument in his book “Creating Innovations: The Making of Young People Who Wil l Change the World” is that our K-12 and college tracks are not consistently “adding the value and teaching the skills that matter most in themarketplace.”This is dangerous at a time when there is increasingly to such things as a high-wage, middle-skilled job—the thing that sustained the middle class in the last generation. Now, there is only a high-wage, high-skilled job. Every middle-class job today is being pulled up, out or down faster than ever. That is, it either requires more skill or can be done by more people around the world or is being buried made obsolete faster than ever. Which is why the goal of education today, argues Wagner, should not be to make every child “college ready” but “innovation ready”—ready to add value to whatever they do.That is a tall task. I tracked Wagner down and asked him to elaborate. “Today,” he said via e-mail,” because knowledge is available on every Internet-connected device, what you know matters far less than what you can do with what you know. The capacity to innovate—the ability to solve problems creatively or bring new possibilities to life and skills like critical thinking,communication and collaboration are far more important than acade mic knowledge. As one executive told me, “We can teach new hires the content. And we will have to because it continues to change, but we can’t teach them how to think—to ask the right questions—and to take initiative.”My generation had it easy. We got to “find” a job. But, more than ever, our kids will have to “invent” a job. Sure, the lucky ones will find their first job, but, given the pace of change today, even they will have to reinvent, re-engineer and reimagine that job much often than their parents if they want to advance in it.“Finland is one of the most innovative economics in the world,”Wagner said,” and it is the only country where students leave high school ‘innovation-ready.’ They lea rn concepts and creativity more than facts, and have a choice of many elective—all with a shorter school day, little homework, and almost no testing. There are a growing number of “reinvented”colleges like the Olin College of Engineering, the M.I.T. Media L ab and the “D-school” Stanford where students learn to innovate.”61.In his book, Wagner argues that _____.A.the education world is hostile to our kidsB.the business world is hostile to those seeking jobsC.the business world is too demanding on the education worldD.the education world should teach what the marketplace demands62. What does the “tall task” refer to in the third paragraph?A. Sustaining the middle class.B. Saving high-wage, middle-skilled jobs.C. Shifting from “college ready” in “innovation ready.”D. Preventing middle-class jobs from becoming obsolete fast.63. What is mainly expressed in Wagner’s e-mail?A. New hires should be taught the content rather than the ways of thinking.B. Knowledge is more readily available on Internet-connected devices.C. Academic knowledge is still the most important to teach.D. Creativity and skills matter more than knowledge.64. What is implied in the fourth paragraph?A. Jobs favor the lucky ones in every generation.B. Jobs changed slowly in the autho r’s generation.C. The author’s generation led an easier life than their kids.D. It was easy for the author’s generation to find their first job.65. What is the purpose of the last paragraph?A. to orient future educationB. to exemplify the necessary shift in educationC. to draw a conclusion about the shift in educationD. to criticize some colleges for their practices in educationPassage 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 economic activity in Canada’s North are important to the country’s future, says Kent Moore, and 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 has already found that thinning sea ice and changes in wind patterns are causing an important change in the marine food chain: phytoplankton(浮游植物)is blooming two 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. “Animal behavio r can evolve over a long time, but these climate changes are happening in the space of a decade, rather than hundreds of years,” 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 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 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 change.C. involves so many countries for different investigationsD. is intended to deal with various aspects in research68. When he says, “Animals can’t change their behavior that quickly,” what does Moore mean bythat quick?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 before.B. is likely to build a novel economy in the region.C. will surely lower the average world temperature.D. needs the research-based supporting information.70. With the drones deployed, as Moore predicts, the researchers will_____.A. involve more collaborating countries than they do now.B. get more data to be required for their research.C. use more novel technologies in research.D. conduct their research at a regular basis.Passage ThreeSkilled clinical history-taking and physical examination remain essential as the basis of the disease diagnosis and management, aided by investigations such as radiological or biochemical tests. Technological advances over the past few decades mean that such investigations now can be refined, or even replaced in some cases, by the measurement of genetic or genomic biomarkers. The molecular characteristics of a disorder or the genetic make-up of an individual can fine tune a diagnosis and inform its management. These new capabilities, often termed “stratified(分层的)” or “personalized” medicine, are likely to have profound effect on the practice of medicine and service delivery.Genetic medicine, which uses genetic or genomic biomarkers in this way, has, until recently, been the province of a small minority of specialized physicians who have used it to diagnose or assess risk of inherited disease. Recognition that most disease has a genetic component, the development and application of new genetic tests to identify important disease subsets and the availability of cost-effective interventions mean that genetic medicine must be integrated more widely across healthcare services. In order to optimize benefit equitably across the population, physicians and services need to be ready to change and adapt to new ways of working.Perhaps the greatest challenge is to ensure the readiness of physicians to use these genomic technologies for maximum effect, so that genetic medicine is incorporated into mainstream specialties. For some clinicians, particularly those involved in clinical research, these advances are already a reality.However, a sizable majority do not yet recognize the relevance of genetics for their clinical practice, perceiving genetic conditions to be rare and untreatable. Maximizing genomic opportunities also means being aware of their limitations, media portrayals that indicate that genetic information gives clear-cut answers are often unrealistic. Indeed, knowing one’s entire genomic seq uence is no the crystal ball of our future that many hope it to be,and physicians will need to be more familiar with what is hype(鼓吹)and what is reality for the integration of genetics into mainstream medicine to be successful.Finally, both professional and public should have a realistic view of what is possible. Although the discovery of genetic risk factors in common diseases such as heart disease and cancer has led to important insights about disease mechanisms, the predictive power of individual genetic variants is often very low. Developments in bioinformatics will need to evolve considerably before the identification of a particular combination of genetic variants in an individual will have clinical utility for them.71.Which of the following statements does the author most probably agree with?A.Personalized medicine will greatly change the practice of medicine.B.Genetic biomarkers have been largely refined over the past.C.Physical examination remains essential in tine tuning a diagnosis.D.Clinical history-taking is no longer important in the genetic era.72.What, according to the second paragraph, can be said of genetic medicine?A. It can offer solutions to all inherited diseases.B. It has been widely recognized among the physicians.C. It necessitates adaptation of the healthcare community.D. It is monopolized by a small minority of specialized physicians.73. The future of the genomic technologies, for the most part, lies in_____.A. the greater potential of treating rare diseasesB. the greater efforts in the relevant clinical researchC. the greater preparedness of the physicians to employ themD. the greater publicity of their benefits in the media portrayals74. In the last paragraph, the author cautions against_____.A. underestimation of the importance of the genetic risk factorsB. unrealistic expectation of the genetic predicative powerC. abuse of genetic medicine in treating common diseasesD. unexpected evolution of the bioinformatics.75. Which of the following can best summarize the main idea of the passage?A. Genetic medicine should be the mainstream option for physicians.B. Genetic medicine poses great challenges to medical practice.C. Genetic medicine will exert great influence on medicine.D. Genetic medicine is defined as “stratified” medicine.Passage FourMisconduct is a word that is always on professors’ minds. Incidents in the news tend to describe the most serious violations of scientific standards, such as plagiarism for fabricating data. But these high-profile infractions(违法)occur relatively rarely. Much more frequent are forms of misconduct that occur as part of the intimate relationship between a faculty member and a student.Faculty members don’t need to commit egregious acts such as sexual harass ment or appropriation of students’work to fail in their responsibility to their charges. Being generally negligent as teachers and mentors should also be seen as falling down on the job.What we found most interesting was how respondents had less vehement(强烈的)reactions to a host of questionable behaviors. In particular, they said that faculty members should avoid neglectful teaching and mentoring. These included routinely being late for classes, frequently skipping appointments with advisees, showing favoritism to some students, ignoring those whose interests diverged from their own, belittling colleagues in front of students, providing little or no feedback on students’ theses or dissertations, and take on more graduate advisees than they could handle.The vast majority of US faculty members have simply not been taught how to teach. And these responses suggest that they are subjecting young scientists-in-training to the same neglect.To address this systemic issue, we must do a better job of exposing the current and next generations of scientists to the rules of proper mentoring through seminars. For instance, on online modules. The societies of academic disciplines, institutions and individual departments can play a big part here, by developing codes of conduct and clear mechanisms for students report violations.The most serious behaviors are relatively easy to spot and address, but “inadequate teaching”can be subjective. Still, if universities establish specific rules for academics to follow, real patterns of abuse will be easier to find. For instance, these rules could stipulate that professors must return substantive feedback on drafts within 15 days, provide more than just negative feedback during a student’s oral defense of their thesis, or be availa ble regularly to answer questions.To deal with faculty members who consistently fall short, universities should establish teaching-integrity committees, similar to the research-integrity committees that handle issues of scientific misconduct. These could receive reports from students and decide what action to take, either by following a due process laid out in the faculty manual, or simply by adopting the same process as that of other committees, such as for tenure applications.76.What is implied in the first two paragraphs?A. The misconducts are widely exposed in the news.。

7. 描述缺氧对细胞代谢的影响。

8. 解释什么是细胞信号转导异常,以及它在疾病中的作用。

答案:6. 病理性钙化是指在非骨骼组织中异常沉积的钙盐,其特点包括钙化部位的非特异性、钙化过程的病理性以及可能伴随的组织损伤。

对机体的影响包括影响组织功能、引起疼痛和功能障碍等。

7. 缺氧时,细胞内ATP生成减少,导致细胞代谢活动受限。

细胞可能通过糖酵解途径产生能量,但效率较低。

长期缺氧可导致细胞损伤甚至死亡。

8. 细胞信号转导异常是指细胞内信号传递过程中的某个环节出现问题,导致细胞功能失调。

这可能涉及到信号分子的异常表达、受体功能的改变或信号传导途径的障碍等。

在疾病中,信号转导异常可能导致细胞增殖失控、细胞凋亡受阻等病理变化。

三、论述题(每题25分,共50分)9. 论述细胞凋亡与坏死的区别及其在疾病中的意义。

10. 阐述肿瘤微环境对肿瘤发展的影响。

答案:9. 细胞凋亡是一种有序的、程序化的细胞死亡过程,通常不引起炎症反应,而坏死是一种非程序化的、由外界因素引起的细胞死亡,常伴随炎症反应。

For eachblank, there are four choices marked A, B, C, and D on the right side.Choose the best answer and mark the letter of your choice on the ANSWERSHEET .For years, scientists have been warning us that the radiation from mobile phones is detrimental to our health, without actually having any evidence to back these __51__ up.However, research now suggests that mobile phone radiation has at least one positive side effect: it can help prevent Alzheimer ’s, __52__ in the mice that acted as test subjects.It’s been suspected, though never proven, that heavy use of mobile phones is bad foryour health.It ’s thought that walking around with a cellphone permanently attached to the side of your head is almost sure to be __53__ your brain. And that may well be true, but I ’d rather wait until it ’s proven before giving up that part of my daily life.But what has now been proven, in a very perfunctory manner, is that mobile phone radiation can have an effect on your brain. __54__ in this case it was a positive ratherthan negative effect.According to BBC news, the Florida Alzheimer ’s Disease Research Center conducted a study on 96 mice to see if the radiation given off by mobile phones could affect the onset of Alzheimer ’s.Some of the mice were “genetically altered to develop beta-amyloid plaques in their brains” __55__ they aged. These are a marker of Alzheimer ’s. all 96 mice were then“exposed to the electro-magnetic __56__ generated by a standard phone for two one-hourperiods each day for seven to nine months. ” The lucky things.__57__ the experiment showed that the mice altered to be predisposed to dementia were protected from the disease if exposed before the onset of the illness. Their cognitiveabilities were so unimpaired as to be virtually __58__ to the mice not genetically altered in any way.Unfortunately, although the results are positive, the scientists don ’t actually know why exposure to mobile phone radiation has this effect. But it ’s hoped that further study and testing could result in a non-invasive __59__ for preventing and treating Alzheimer ’s disease.Autopsies carried out on the mice also concluded no ill-effects of their exposure to the radiation.However, the fact that the radiation prevented Alzheimer ’s means mobile phones __60__ our brainsand bodies in ways not yet explored. And it ’s sure there are negative as well as this one positive.51. A. devicesB.risksC.phenomenaD.claims52. A. at leastB.at mostC.as ifD.as well53. A. blockingB.cookingC.exhaustingD.cooling54. A.

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 onthe ANSWER SHEET .Passage oneI have just returned from Mexico, where I visited a factory making medical masks.Faced with fierce competition, the owner has cut his costs by outsourcing some of his production. Scores of people work for him in their homes, threading elastic into masks by hand. They are paid below the minimum wage, with no job security and no healthcare provision.Users of medical masks and other laboratory gear probably give little thought to where their equipment comes from. That needs to change. A significant proportion of these products are made in the developing world by low-paid people with inadequate labor rights.This leads to human misery on a tremendous scale.Take lab coats. Many are made in India, where most cotton farmers are paid an unfair price for their crops and factory employees work illegal hours for poor pay.One-fifth of the world ’s surgical instruments are made in northern Pakistan. WhenI visited the area a couple of years ago I found most workers toiling 12 hours a day,seven days a week, for less than a dollar a day, exposed to noise, metal dust and toxic chemicals. Thousands of children, some as young as 7, work in the industry.To win international contracts, factory owners must offer rock-bottom prices, and consequently drive down wages and labor conditions as far as they can. We laboratory scientists in the developed world may unwittingly be encouraging this: we ask how much our equipment will cost, but which of us asks who made it and how much they were paid?This is no small matter. Science is supposed to benefit humanity, but because of the conditions under which their tools are made, may scientists may actually be causing harm.What can be done? A knee-jerk boycott of unethical goods is not the answer; it would just make things worse for workers in those manufacturing zones. What we need is to start asking suppliers to be transparent about where and how their products are manufactured and urge them to improve their manufacturing practices.It can be done. Many universities are committed to fair trade in the form of ethically sourced tea, coffee or bananas. That model should be extended to laboratory goods.There are signs that things are moving. Over the past few years I have worked with health services in the UK and in Sweden. Both have recently instituted ethical procurement practices. If science is truly going to help humanity, it needs to follow suit.61.From the medical masks to lab coats, the author is trying to tell us .A.the practice of occupational protection in the developing worldB.the developing countries plagued by poverty and disease.C.the cheapest labor in the developing countries.D.the human misery behind them.62.The concerning phenomenon the author has observed, according to the passage,A.is nothing but the repetition of the miserable history.B.could have been even exaggerated.C.is unfamiliar to the wealthy west.D.is prevailing across the world.63.The author argues that when researchers in the wealthy west buy the tools of theirtrade, they should _______________ .A.have the same concern with the developing countries.B.be blind to their sources for the sake of humanityC.pursue good bargains in the international market.D.spare a thought for how they were made.64. A proper course of action suggested by the author is ______ .A.to refuse to import the unethical goods from the developing world.B.to ask scientists to tell the truth as the prime value of their work.C.to urge the manufacturers to address the immoral issues.D.to improve the transparency of international contracts.65.By saying at the end of the passage that if science is truly going to help humanity, it needs to follow suit, the author means that .A.the scientific community should stand up for all humanityB.the prime value of scientists’ work is to tell the truth.boratory goods also need to be ethically sourced.D.because of science, there is hope for humanity.Passage twoA little information is a dangerous thing. A lot of information, if it ’sinaccurate orconfusing, even more so. This is a problem for anyone trying to spend or invest in anenvironmentally sustainable way. Investors are barraged with indexes purporting to describe companie’s eco-credentials, some of dubious quality. Green labels on consumer products are ubiquitous, but their claims are hard to verify.The confusion is evident form New Scientist’ s analysis of whether public perceptions of companies’ green credentials reflect reality. It shows that many companies considered“ green” have done little to earn that reputation, while others do not get sufficient credit for their efforts to reduce their environmental impact. Obtaining better information is crucial, because decisions by consumers and big investors will help propel us towards a green economy.At present, it is too easy to make unverified claims. Take disclosure of greenhouse gas emissions, for example. There are voluntary schemes such as the Carbon Disclosure Project, but little scrutiny of the figures companies submit, which means investors may be misled.Measurements can be difficult to interpret, too, like those for water sue. In this case, context is crucial: a little from rain-soaked Ireland is not the same as a little drawn from the Arizona desert.Similar problems bedevil “green” labels attached to individual products. Here, the computer equipment rating system developed by the Green Electronics Council shows the way forward. Its criteria come from the IEEE, the world ’s leading professional association for technology/Other schemes, such as the “sustainability index” planned by US retail giant Walmart, are broader. Developing rigorous standards for a large number of different types of product will be tough, placing a huge burden on the academic-led consortium that is doing the underlying scientific work.Our investigation also reveals that many companies choose not to disclose data. Some will want to keep it that way. This is why we need legal requirements for full disclosure of environmental information, with the clear message that the polluter will eventually be required to pay. Then market forces will drive companies to clean up their acts.Let ’s hope we can rise to this challenge. Before we can have a green economy we need a green information economy — and it s the quality of information, as well as its quantity, that will count.66.T“he confusion ” at the beginning of the 2 nd paragraph refers to .A.where to spend or invest in a sustainable wayB.an array of consumer products to chooseC.a fog of unreliable green informationD.little information on eco-credibility67.From the New Scientist’ s analysis it can be inferred that in many casesA.eco-credibility is abusedB.a green economy is crucialC.an environmental impact is lessenedD.green credentials promote green economy68.From unverified claims to difficult measurements and then to individual products, the author argues that ______ .A.eco-credibility is a game between scientists and manufacturesB.neither scientists nor manufactures are honestC.it is vital to build a green economyD.better information is critical69.To address the issue, the author is crying for _.A.transparent corporate managementB.establishing sustainability indexesC.tough academic-led surveillanceD.strict legal weapons70.Which of the following can be the best inference from the last paragraph?A.The toughest challenge is the best opportunity.B.It is time for another green revolution.rmation should be free for all.D.No quantity, no quality.Passage ThreePeople are extraordinarily skilled at spotting cheats — much better than they are detecting rule-breaking that does not involve cheating. A study showing just how good we are at this adds weight to the theory that our exceptional brainpower arose through evolutionary pressures to acquire specific cognitive skills.The still-controversial idea that humans have specialized decision-making systems in addition to generalized reasoning has been around for decades.Its advocatespoint out that the ability to identify untrustworthy people should be favored evolutionarily, since cheats risk undermining the social interactions in which people trade goods or services for mutual benefit.The test whether we have a special ability to reason about cheating, Leda Cosmides, an evolutionary psychologist at the University of California, Santa Barbara, and her colleagues used a standard psychological test called the Wason selection task, which tests volunteers’ ability to reason about “if/then” statements.The researchers set up scenarios in which they asked undergraduate volunteers to imagine they were supervising workers sorting appliances for admission to two schools; a good one in a district where school taxes are high, and a poor one in an equally wealthy, but lightly taxed district. The hypothetical workers were supposed to follow a rule that specified “if a student is admitted to the good school ”, they must live in the highly taxed district.Half the time, the test subjects were told that the workers had children of their own applying to the schools, thus having a motive to cheat; the rest of the time they were told the workers were merely absent-minded and sometimes made innocent errors. Then the test subjects were asked how they would verify that the workers were not breaking the rule.Cosmides found that when the “supervisors” thought they were checking for innocent errors, just 9 of 33, or 27 percent, got the right answer - looking for a student admitted to the good school who did not live in the highly taxed district. In contrast, when the supervisors thought they were watching for cheats, they did much better, with 23 of 34, or 68 percent, getting the right answer.This suggests that people are, indeed, more adept at spotting cheat than at detecting mere rule-breaking, Cosmides said.“Any cues that it ’s just an innocent mistake actually inactivate the detection mechanism”.Other psychologists remain skeptical of this conclusion. “If you want to conclude that therefore there’ s a module in the mind for detecting cheaters, I see zero evidence for that, ” says Steven Sloman, a cognitive scientists at Brown University in Province, Rhode Island. “It’s certainly possible that it’s something we learned through experience.There’ s no evident that it’s anything innate.”71.The findings of the study were in favor of ______ .A.the highly developed skills of cheating at schoolB.the relation between intelligence and evolutionC.the phenomenon of cheating at schoolD.the human innate ability to cheat72.The test “supervisors” appeared to be more adept at __ .A.spotting cheats than detecting mere rule-breakingB.detecting mere rule-breaking than spotting cheatsC.spotting their own children cheating than others doing itD.detecting cheats in the highly taxed district than in the lightly taxed one73.When she says that …that can't be the only thing going on in the mind, Cosmides most probably implies that ________________ .A.cheating is highly motivated in the social interactionsB.our specific cognitive skills can serve an evolutionary purposeC.there is no such a mental thing as a specialized decision-making systemD.the ability to identify untrustworthy people should be favored evolutionary74.In response to Cosmides’ claim, Sloman would say that ___ .A.it was of great possibilityB.it could be misleadingC.it was unbelievableD.it ’s acquired75.Which of the following can be the best title for the passage?A.Cheating at SchoolB.Cheating as the Human NatureC.Imaginary Intelligence and CheatingD.Intelligence Evolved to Root Out CheatsPassage FourFor many environmentalists, all human influence on the planet is bad. Many natural scientists implicitly share this outlook. This is not unscientific, but it can create the impression that greens and environmental scientists are authoritarian tree-huggers who value nature above people. That doesn’ t play well with mainstream society, as the apparent backlash against climate science reveals.Environmentalists need to find a new story to tell. Like it or not, we now live in the anthropocene 人类世)-an age in which humans are perturbing many of the planet s natural systems, from the water cycle to the acidity of the oceans. We cannot wish that away; we must recognize it and manage our impacts.Johan Rockstrom, head of the Stockholm Environment Institute in Sweden, and colleagues have distilled recent research on how Earth systems work into a list of nine “planetary boundaries” that we must stay within to live sustainably. It ispreliminary work, and many will disagree with where the boundaries are set. But the point is to offer a new way of thinking about our relationship with the environment —a science-based picture that accepts a certain level of human impact and even allows us some room to expand. The result is a breath of fresh air: though we are already well past three of the boundaries, we haven’ t trashed the place yet.It is in the same spirit that we also probe the basis for key claims in the Intergovernmental Panel on Climate Change’ s 2007 report on climate impacts. Thisreport has been much discussed since our revelations about its unsubstantiated statement on melting Himalayan glaciers. Why return to the topic? Because there is a sense thatthe IPCC shares the same anti-human agenda and, as a result, is too credulous of unverified numbers. While the majority of the report is assuredly rigorous, there is no escaping the fact that parts of it make claims that go beyond the science.For example, the chapter on Africa exaggerates a claim about crashes in farm yields, and also highlights projections of increased water stress in some regions while ignoring projections in the same study that point to reduced water stress in other regions. There errors are not trifling. They are among the repor’ ts headline conclusions.Above all, we need a dispassionate view of the state of the planet and our likely future impact on it. There ’s no room for complacency: Rockstrom ’s analysis shows us that we face real dangers, but exaggerating our problems is not the way to solve them.76.As the first paragraph implies, there is between environmentalists and mainstream society _________________________ .A. a misunderstandingB.a confrontationC. a collaborationD.a consensus77.Within the planetary boundaries, as Rockstrom implies, ______.A.we humans have gone far beyond the limitationsB.our human activities are actually moderate in degreeC. a certain level of human impact is naturally acceptableD.it is urgent to modify our relationship with the environment78.The point, based on Rockstrom ’s investigation, is simply that __ .A.they made the first classification of Earth systemsB.it is not to deny but to manage impacts on the planetC.we are approaching the anthropocene faster than expectedD.human beings are rational and responsible creatures on earth79.Critical of the IPCC ’s 2007 report, the author argues that they .A.missed the most serious problems thereB.were poorly assembled for the missionC.cannot be called scientists at allD.value nature above people80.It can be concluded from the passage that if we are to manage the anthropocene successfully, we ______________________________ .A.must redefine our relationship with the environmentB.should not take it seriously but to take it easyC.need a new way of thinking about natureD.need cooler heads and clearer statisticsPassage Five。
