Choose the best answer and mark the letter of your choice on the ANSWER SHEIET.A mother who is suffering from cancer can pass on the disease to her unborn child in extremely rare cases, 51 a new case report published in PNAS this week.According to researchers in Japan and at the Institute for Cancer Research in Sutton, UK, a Japanese mother had been diagnosed with leukemia a few weeks after giving birth, 52 tumors were dis covered in her daughter’s cheek and lung when she was 11 months old. Genetic analysis showed that the baby’s cancer cells had the same mutation as the cancer cells of the mother. But the cancer cells contained no DNA whatsoever from the father, 53 would be expected if she had inherited the cancer from conception. That suggests the cancer cell made it into the unborn child’s body across the placental barrier.The Guardian claimed this to be the first 54 case of cells crossing the placental barrier. But this is not the case—microchimerism, 55 cells are exchanged between a mother and her unborn child, is thought to be uite common, with some cells thought to pass from fetus to mother in about 50 to 75 per cent of cases and to go the other way about half 56 .As the BBC pointed out, the greater 57 in cancer transmission from mother to fetus had been how cancer cells that have slipped through the placental barrier could survive in the fetus withoutcancer cells, which led to the 58 of the specific features that would have allowed the fetal immune system to detect the cells as foreign. As a result, no attack against the invaders was launched.59 , acco rding to the researchers there is little reason for concern of “cancer danger〞. Only 17 probable cases have been reported worldwide and the combined 60 of cancer cells both passing the placental barrier and having the right mutation to evade the baby’s imm une system is extremely low.51. A. suggests B. suggesting C. having suggested D. suggested52. A. since B. although C. whereas D. when53. A. what B. whom C. who D. as54. A. predicted B. notorious C. proven D. detailed55. A. where B. when C. if D. whatever56. A. as many B. as much C. as well D. as often57. A. threat B. puzzle C. obstacle D. dilemma58. A. detection B. deletion C. amplification D. addition59. A. Therefore B. Furthermore C. Nevertheless D. Conclusively60. A. likelihood B. function C. influence D. flexibilityPart ⅣReading Comprehension (30%)Directions: In this part there are six passages, each of which is followed by five uestions. For each uestion 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 oneThe American Society of Clinical Oncology wrapped its annual conference this week, going through the usual motions of presenting a lot of drugs that offer some added uality or extension of life to those suffering from a variety of as-yet incurable diseases. But buried deep in an AP story are a couple of promising headlines that seems worthy of more thorough review, including one treatment study where 100 percent of patients saw their cancer diminish by half.First of all, it seems pharmaceutical companies are moving away from the main cost-effective one-size-fits-all approach to drag development and embracing the long cancer treatments, engineering drags that only work for a small percentage of patients but work very effectively within that group.Pfizer announced that one such drug it’s pushing into late-stage testing is target for 4% of lung cancer patients. But more than 90% of that tiny cohort responded to the drug initial tests, and 9 out of ten is getting pretty close to the ideal ten out of ten. By gearing toward more boutiue treatments rather than broad umbrella pharmaceuticals that try to fit for everyone it seems cancer researchers are making some headway. But how can we close the gap on that remaining ten percent Ask Takeda Pharmaceutical and Celgene, two drug makers who put aside competitive interests to test a novel combination of their treatments. In a test of 66 patients with the blood diseasesay, a 100 percent response to a cancer drug (or in this case a drug cocktail) is more or less unheard of. Moreover, this combination never would’ve been two competing companies hadn’t sat down and put their heads together.Are there more potentially effective drug combos out there separated by competitive interest and proprietary information Who’s to say, but it seems like with the amount of money and research being pumped into cancer drug development, the outcome pretty good. And if researchers can start pushing more of their response numbers toward 100 percent, we can more easily start talking about oncology’s favorite four-letter word: cure.61.Which of the following can be the best title for the passagepetition and CooperationB.Two Competing Pharmaceutical CompaniesC.The Promising Future of PharmaceuticalsD.Encouraging News: a 100% Response to a Cancer Drug62.In cancer drug development, according to the passage, the pharmaceuticals now .A.are adopting the cost-effective one-size-fits-all approachB.are moving towards individualized and targeted treatmentsC.are investing the lion’s shares of their moneyD.care only about their profits63.From the encouraging advance by the two companies, we can infer that .A.the development can be ascribed to their joint efforts and collaborationB.it was their competition that resulted in the accomplishmentC.other pharmaceuticals will join them in the researchD.the future cancer treatment can be nothing but cocktail therapy64.From the last paragraph it can be inferred that the answer to the uestion .A. is nowhere to be foundB. can drive one crazyC. can be multipleD. is conditional65.The tone of the author of this passage seems to be .A. neutralB. criticalC. negativeD. optimistPassage TwoLiver disease is the 12th leading cause of death in the U.S., chiefly because once it’s determined that a patient needs a new liver it’s very difficult to get one. Even in case where a suitable donor match is found, there’s g uarantee a transplant will be successful. But researchers at Massachusetts General Hospital have taken a huge step toward building functioning livers in the lab, successfully transplanting culture-grown livers into rats.The livers aren’t grown from scratc h, but rather within the infrastructure of a donor liver. The liver cells in the donor organ are washed out with a detergent that gently strips away the liver cells, leaving behind a biological scaffold of proteins and extracellular architecture that is very hard toWith all of that complicated infrastructure already in place, the researchers then seeded the scaffold〔支架〕with liver cells isolated from healthy livers, as well as some special endothelial cells to line the bold vessels. Once repopulated with healthy cells, these livers lived in culture for 10 days.The team also transplanted some two-day-old recellularized livers back into rats, where they continued to thrive for eight hours while connected into the rats’ va scular systems. However, the current method isn’t perfect and cannot seem to repopulate the blood vessels uite densely enough and the transplanted livers can’t keep functioning for more than about 24 hours (hence the eight-hour maximum for the rat transplant).But the initial successes are promising, and the team thinks they can overcome the blood vessel problem and get fully functioning livers into rats within two years. It still might be a decade before the tech hits the clinic, but if nothing goes horribly wrong —and especially if stem-cell research establishes a reliable way to create health liver cells from the every patients who need transplants lab-generated livers that are perfect matches for their recipients could become a reality.66.It can be inferred from the passage that the animal model was mainly intended to .A.investigate the possibility of growing blood vessels in the labB.explore the unknown functions of the human liverC.reduce the incidence of liver disease in the U.S.D.address the source of liver transplants67.What does the author mean when he says that the livers aren’t grown from s cratchA.The making of a biological scaffold of proteins and extracellular a rchitecture.B.A huge step toward building functioning livers in the lab.C.The building of the infrastructure of a donor livenD.Growing liver cells in the donor organ.68.The biological scaffold was not put into the culture in the lab until .A.duplicated syntheticallyB.isolated from the healthy liverC.repopulated with the healthy cellsD.the addition of some man-made blood vessels69.What seems to be the problem in the planted liverA.The rats as wrong recipients.B.The time point of the transplantation.C.The short period of the recellularization.D.The insufficient repopulation of the blood vessels.70.The research team holds high hopes of .A.creating lab-generated livers for patients within two yearsB.the timetable for generating human livers in the labD.building a fully functioning liver into ratsPassage ThreePatients whose eyes have suffered heat or chemical burns typically experience severe damage to the cornea the thin, transparent front of the eye that refracts light and contributes most of the eve’s focusing ability. In a long-term study, Italian researchers use stem cells taken from the limbus, the border between the cornea and the white of the eye, to cultivate a graft of healthy cells in a lab to help restore vision in eyes. During the 10-years study, the researchers implanted the healthy stem cells into the damaged cornea in 113 eyes of 112 patients. The treatment was fully successful in more than 75 percent of the patients, and partially successful in 13 percent. Moreover, the restored vision remained stable over 10 years. Success was defined as an absence of all symptoms and permanent restoration of the cornea.Treatment outcome was initially assessed at one year, with up to 10 years of follow-up evaluations. The procedure was even successful in several patients whose burn injuries had occurred years earlier and who had already undergone surgery.Current treatment for burned eyes involves taking stem cells from a patient’s healthy eye, or from the eyes of another person, and transferring them to the burned eye. The new procedure, however, stimulates the lim bal stem cells from the patient’s own eye to reproduce in a lab culture. Several types of treatments using stem cells have proven successful in restoring blindness, but the long-term effectiveness shown here is significant. The treatment is only for blindness caused by damage to the cornea; it is not effective for repairing damaged retinas or optic nerves.Chemical eye bums often occur in the workplace, but can also happen due to mishaps involving household cleaning products and automobile batteries.The r esults of the study, based at Italy’s University of Modena and Reggio Emilia, were published in the June 23 online issue of the New England Journal of Medicine.71.What is the main idea of this passageA.Stem cells can help restore vision in the eyes blinded by burns.B.The vision in the eyes blinded by bums for 10 years can be restored.C.The restored vision of the burned eyes treated with stem cells can last for 10 years.D.The burned eyes can only be treated with stem cells from other healthy persons.72.The Italian techniue reported in this passage .A.can repair damaged retinasB.is able to treat damaged optic nervesC.is especially effective for burn injuries in the eyes already treated surgicallyD.shows a long-term effectiveness for blindness in vision caused by damage to cornea73.Which of the following is NOT mentioned about eye burnsA.The places in which people work.B.The accidents that involve using household cleaning products.D.The disasters caused by battery explosion at home.74.What is one of the reuirements for the current approachA.The stem cells taken from a healthy eye.B.The patient physically healthy.C.The damaged eye with partial vision.D.The blindness due to damaged optic nerves.75.Which of the following words can best describe the author’s attitude towards the new methodA. Sarcastic.B. Indifferent.C. Critical.D. Positive.Passage FourHere is a charming statistic: divide the US by race, sex and county of residence, and differences in average life expectancy across the various groups can exceed 30 years. The most disadvantaged look like denizens of a poor African country: a boy born on a Native American reservation in Jackson County, South Dakota, for example, will be lucky to reach his 60th birthday.A typical child in Senegal can expect to live longer than that.America is not alone in this respect. While the picture is extreme in other rich nations, health ineualities based on race, sex and class exist in most societies—and are only partly explained by access to healthcare.But fresh insights and solutions may soon be at hand. An innovative project in Chicago to unite sociology and biology is blazing the trai〔l开创〕，after discovering that social isolation and fear of crime can help to explain the alarmingly high death rate from breast cancer among the city’s black women. Living in these conditions seems to make tumors more aggressive by changing gene activity, so that cancer cells can use nutrients more effectively.We are already familiar with the lethal effect of stress on people clinging to the bottom rungs of the societal ladder, thanks to pioneering studies of British civil servants conducted by Michael Marmot of University College London. What’s exciting about the Chicago project is that it both probes the mechanisms involved in a specific disease and suggests precise remedies. There are drugs that may stave tumors of nutrients and community coordinators could be employed to help reduce social isolation. Encouraged by the US National Institutes of Health, similar projects are springing up to study other pockets of poor health, in populations ranging from urban black men to white poor women in rural Appalachia.To realize the full potential of such projects, biologists and sociologists will have to start treating one other with a new respect and learn how to collaborate outside their comfort zones. Too many biomedical researchers still take the arrogant view that sociology is a “soft science〞with little that’s serious to say about health. And too many so ciologists reject any biological angle—fearing that their expertise will be swept aside and that this approach will be used to bolster discredited theories of eugenics, or crude race-based medicine.It’s time to drop these outdated attitudes and work together for the good of society’s mostpublic policy.This endeavor has huge implications, not least in cutting the wide health gaps between blacks and whites, rich and poor.76.As shown in the 1st paragraph, the shaming statistic reflects .A. injustice everywhereB. racial discriminationC. a growing life spanD. health ineualities77.Which of the following can have a negative impact on health according to the Chicago-basedprojectA.Where to live.B.Which race to belong to.C.How to adjust environmentally.D.What medical problem to suffer.78.The Chicago-based project focuses its management on .A.a particular medical problem and its related social issueB.racial discrimination and its related social problemsC.the social ladder and its related medical conditionsD.a specific disease and its medical treatment79.Which of the following can most probably neglected by sociologistsA. The racial perspective.B. The environmental aspect.C. The biological dimension.D. The psychological angel.80.The author is a big fan of .A.the combination of a traditional and new way of thinking in promoting healthB.the integration of biologists and sociologists to reduce health ineualitiesC.the mutual understanding and respect between racesD.public education and health promotionPassage FiveAmerican researchers are working on three antibodies that many mark a new step on the path toward an HIV vaccine, according to a report published online Thursday, July 8, 2022, in the journal Science.One of the antibodies suppresses 91 percent of HIV strains, more than any AIDS antibody ever discovered, according to a report on the findings published in the Wall Street Journal. The antibodies were discovered in the cells of a 60-year-old African-American gay man whose body produced them naturally. One antibody in particular is substantially different from its precursors, the Science study says.The antibodies could be tried as a treatment for people already infected with HIV, the WSJ reports. At the very least, they might boost the efficacy of current antiretroviral drugs. It is welcome news for the 33 million people the United Nations estimated were living with AIDS at the end of 2022.the African-American man, known as Donor 45. First they designed a probe that looks just like a spot on a particular molecule on the cells that HIV infects. They used the probe to attract only the antibodies that efficiently attack that spot. They screened 25 million of Donor 45’s cell to find just 12 cells that produced the antibodies.Scientists have already discovered plenty of antibodies that either don’t work at all or only wo rk on a couple of HIV strains. Last year marked the first time that researchers found “broadly neutralizing antibodies,〞which knock out many HIV strains. But none of those antibodies neutralized more than about 40 percent of them, the WSJ says. The newest antibody, at 91 percent neutralization, is a marked improvement.Still, more work needs to be done to ensure the antibodies would activate the immune system to produce natural defenses against AIDS, the study authors say. They suggest there test methods that blend the three new antibodies together—in raw form to prevent transmission of the virus, such as from mother to child; in a microbicide gel that women or gay men could use before sex to prevent infection; or as a treatment for HIV/AIDS, combined with antiretroviral drug.If the scientists can find the right way to stimulate production of the antibodies, they think most people could produce then, the WSJ says.81.We can learn from the beginning of the passage that .A.a newly discovered antibody defeats 91% of the HIV strainsB.a new antiretroviral drug has just come on the marketC.American researchers have developed a new vaccine for HIVD.the African-American gay man was cured of his HIV infection82.What is the implication of the antibodies discovered in the cells of the African-American gaymanA.They can cure the 33 million AIDS patients in the world.B.They may strengthen the effects of the existing antiretroviral drags.C.They will kill all the HIV viruses.D.They will help make a uick diagnosis of an HIV infection.83.The newest antibody found in Donor 45 reflects a dramatic advance in terms of .A. pathologyB. pharmacologyC. HIV neutralizationD. HIV epidemiology84.According to the study authors,the three test methods are intended to .A.advance the technology in condom production to prevent HIV infectionB.facilitate the natural immune defense against AIDSC.Develop more effective antiretroviral drugsD.Develop more effective antiretroviral drugs85.The passage is mot likely .A.news report。

For each uestion 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 OnePatients can recall what they hear while under general anesthetic even if they don't wake up, concludes a new study.Several studies over the past three decades have reported that people can retain conscious or subconscious memories of things that happened while they were being operated on.But failure by other researchers to confirm such findings has led skeptics to speculate that the patients who remembered these events might briefly have regained consciousness in the course of operations.anesthesia using bispectral analysis,a techniue which measures changes in brainwave patterns in the frontal lobes moment by moment during surgery. Before this study,researchers only took an average measurement over the whole operation, says Lubke.Lubke studied 96 trauma patients undergoing emergency surgery, many of whom were too severely injured to tolerate full anesthesia. During surgery, each patient wore headphones trough which a series of 16 words was repeated for 3 minutes each. At the same time, bispectral analysis recorded the depth of anesthesia.After the operation, Lubke tested the patients by showing therm the fist three letters of a word, such as “lim〞,and asking them to complete it. Patients who had had a word starting with these letters played during surgery—“limit〞for example—chose that word an average of 1I percent more often than patients who had been played a different word list. None of the patients had any conscious memory of hearing the word list.Unconscious priming was strongest for words played when patients were most lightly anaesthetized. But it was statistically significant even when patients were fully anaesthetized when the word was played.This finding, which will be published in the journal Anesthesiology could mean that operating theatre staff should be more discreet. What they say during surgery may distress patients afterwards, says Philip Merikle, a psychologist at the University of Waterloo, Ontario.61.Scientists have found that deep anesthesiaA.is likely to affect hearingB.cannot block surgeons’ wordsC.can cause serious damages to memoryD.helps retain conscious or subconscious memories62.By the new study, the techniue of bispectral analysis helps the scientistsA.acuire an average measurement of brainwave changes over the whole surgeryB.decide whether the patient would retain conscious or subconscious memoriesC.relate their measurements and recordings to the verbal sounds during surgeryD.assure the depth of anesthesia during surgery63.To test the patients,the scientistsA.prepared two lists of wordsed ninety-six headphones for listeningC.conducted the whole experiment for three minutesD.voiced only the first three letters of sixteen words during surgery64.The results from the new study indicate that it was possible for the patientsA.to regain consciousness under the knife.B.to tell one word from another after surgery.C.to recall what had been heard during surgery.65.What we can infer from the findingA.How surgical malpractice can be prevented.B.Why a surgeon cannot be too careful.C.Why surgeons should hold their tongues during surgery.D.How the postoperative patients can retain subconscious memories.Passage TwoScientists used to believe adult brains did not grow any new neurons,but it has emerged that new neurons can sprout in the brains of adult rats,birds and even humans.Understanding the process could be important for finding ways to treat diseases such as Alzheimer's in which neurons are destroyed.Most neurons sprouting in adulthood seem to be in the hippocampus,a structure involved in learning and memory. But they rarely survive more than a few weeks. “We thought they were possibly dying because they were deprived of some sort of input.〞says Elizabeth Gould, a neuroscientist at Princeton. Because of the location, Gould and her colleagues suspect that learning itself might bolster the new neurons’ survival, and that only tasks involving the hippocampus would do the trick.To test this,they injected adult male rats with a substance that labeled newborn neurons so that they could be tracked. Later,they gave some of the rats standard tasks. One involved using visual and spatial cues, such as posters on a wall, to learn to find a platform hidden under murky water. In another, the rats learnt to associate a noise with a tiny shock half a second later. Both these tasks use the hippocampus—if this structure is damaged, rats can’t do them.Meanwhile,the researches gave other rats similar tasks that did not reuire the hippocampus. finding a platform that was easily visible in water, for instance. Other members of the control group simply paddled in a tub of water or listened to noises.The team report in Nature Neuroscience that the animals given the tasks that activate the hippocampus kept twice as many of their new neurons alive as the others. “Learning opport unities increase the number of neurons,〞 says Gould.But Fred Gage and his colleagues at the Salk Institute for Biological Studies in La Jolla,California,dispute this. In the same issue of Nature Neuroscience, they report that similar water maze experiments on mice did not help new neurons survive.Gould thinks the difference arose because the groups labeled new neurons at different times. Her team gave the animals tasks two weeks after the neurons were labeled. When the new cells would normally be dying. She thinks the Salk group put their mice to work too early for new neurons to benefit. “By the time the cells were degenerating, the animals were not learning anything,〞she says.66.Not until recently did scientists find out thatA.new neurons could grow in adult brainsC.neurons were destroyed in Alzheimer's diseaseD.humans could produce new neurons as animals67.Gould’s notion was that the short-lived neuronsA.did survive longer than expectedB.would die much sooner than expected couldC.could actually better learning and memoryD.could be kept alive by stimulating the hippocampus68.Which of the following can clearly tell the two groups of rats from each other in the testA. The water used.B. The noises played.C. The neurons newly born.D. The hippocampus involved.69.Gould theorizes that the Salk group’s failure to report the same results was due t oA. the timing of labeling new neuronsB. the freuency of stimulationC. the wrongly labeled neuronsD. the types of learning tasks70.Which of the following can be the best title for the passageA. Use It or Lose ItB. Learn to SurviveC. To Be or Not to BeD. Stay Mentally HealthyPassage ThreeHere’s yet another reason to lose weight. Heavier people are more lik ely to be killed or seriously injured in car accidents than lighter people.That could mean car designers will have to build in new safety features to compensate for the extra hazards facing overweight passengers. In the U. S., car manufacturers have already had to redesign air bags so they inflate to lower pressures making them less of a danger to smaller women and children. But no one yet knows what it is that puts overweight passengers at extra risk.A study carried out in Seattle, Washington looked at more than 26 000 people who had been involved in car crashes, and found that heavier people at far more risk. People weighing between 100 and 119 kilograms are almost two-and-a-half lines as likely to die in a crash as people weighing less than 60 kilo- grams.And importantly, the same trend held up when the researchers looked at body mass index (BMI)—a measure that takes height as well as weight into account. Someone 1.8 meters tall weighing 126 kilograms would have a BMI of 39, but so would a person 1.5 meters tell weighing 88 kilograms. People are said to be obese if their BMI is 30 or over.The study found that people with a BMI of 35 to 39 are over twice as likely to die in a crash compared with people with BMIs of about 20. It’s not just total weight, but obesity itself that’s dangerous.While they do not yet know why this is the case, the evidence is worth pursuing, says Charles Mack, a surgeon and epidemiologist at the Harborview Injury Prevention and Research Center in Seattle,who led the research team. He thinks one answer maybe for safety authorities to use heavierCrash tests normally use dummies that represent standard-sized males weighing about 78 kilograms. Recently, smaller crash-test dummies have also been used to represent children inside crashing cars. But larger and heavier dummies aren’t used, the U.S.National Highway Traffic Safety Administration in Washington DC told New Scientist.The reasons for the higher injury and death rates are far from clear, Mock speculates that car interiors might not be suitably designed for heavy people. Or obese people, with health problems such as high blood pressure or diabetes, could be finding it tougher to recover from injury.71.When they redesigned air bags to hold less pressure, the American car manufacturers .A.found it hard to set standards without the definition of obesityB.incidentally brought about extra risks to obese passengersC.based their job on the information of car accidentsD.actually neglected smaller women and children72.When they categorized the obese people, the researchers .A.showed a preference for BMI in measurementsB.achieved almost the same results as previouslyC.found the units of kilogram more applicable than BMID.were shocked to know the number of obese people killed in car crashes73.To address the problem, Mock .A.suggested that the safety authorities use heavier crash-test dummiesB.cried for the standardization of crash-test dummiesC.reduced the weights of crash-test dummiesD.encouraged obese people to lose weight74.While exploring the reason for the higher injury and death rates, Mock would most probablysay that .A.cars can be made safer to avoid cashesB.it is wise for obese people not to drive drunkC.it is not just total weight, but obesity itself that is dangerousD.the main reason behind the problem is drinkers’ heavy weight75.Which of the following uestions is closely related to the passageA.Are air bags really necessary to be built in carsB.Are cars certified as safe to driveC.Are crash-test dummies too thinD.Are car accidents preventablePassage FourIt seems intuitive that going to a specialist physician will result in more thorough and up-to-date care for whatever ails you. In fact, many studies support this idea-but health-Care researchers caution that they may not tell the whole story.of disease,but generalist—family physicians and general practitioners—are more likely to treat patients with several coexisting diseases.A second uestion is what counts as the most valuable treatment Specialists are more familiar with standards of care for the diseases they treat regularly,says Harlan M. Krumholz of Yale University. On the oth er hand, a generalist may do a better job of coordinating a patient’s care and keeping an eye on a person’s overall health, says Martin T. Donohoe of the Oregon Health Sciences University in PortlandTo further complicate comparisons, many generalists will consult with specialists on complicated cases, but medical records do not always show that, says Carolyn Clancy of the Agency for Health Care Policy and Research in Rockville, Md.That said, stroke patients treated by neurologists are more likely to survive than stroke patients treated by generalists. Among about 3800sroke sufferers nationwide,16.1 percent of those treated by a neurologist died within 3 months, compared with 25.3 percent of those treated by family physicians.Several studies have shown that people with heart disease fare better when they are treated by cardiologists,says Ira S. Nash of the Mount Sinai Medical Center in New York, but it’s hard to figure out exactly why.“Physician specialty, in addition to being a measure of formal training in the field, is also a proxy for clinical experience,〞 he says. “It’s very difficult to separate out the overlapping concepts: one, that practice makes perfect; two,the effect of the educational and time investments in a clinical problem the physician is simply interested in; and three,the issue of formal training.〞Differences between specialist care and generalist care, however, pale in comparison with the finding that both specialists and generalists often fail to put the latest knowledge into practice, contend both Donohoe and Clancy. A report by the U.S. General Accounting Office documented that heart attack survivors who saw cardiologists regularly were more likely to take cholesterol-lowering drugs and beta blockers—which reduce heart rate and blood pressure—than those who received care from a generalist. Even so, these life-prolonging drugs were not prescribed to many patients who appeared to be eligible for them, implying that both generalists and specialists could do better.“Maybe we are focusing too much energy on the differences between generalist and specialist care,〞 says Donohoe. Perhaps,he adds, “we should focus more intently on improving the uality of communication and cooperation between generalists and specialists and on developing and promoting practice guidelines that might have a much bigger effect on the overall health of Americans.〞76.Which of the following uestions can most probably come out of the two uestions raised in thepassageA. Is specialist care superiorB. What is specialist care all about77.The answers to the two uestions suggest that .A.generalists are more likely to be ignoredB.a specialist can be a generalist, or vice versaC.neither of the two groups is better than the otherD.patients have every reason to go to specialist physicians78.According to the passage,the better treatment of stroke and heart disease on the part ofspecialists .A.cannot simply be ascribed to specialtyB.is hard to be justified on the nationwide scaleC.is enough to prove the superiority of specialist careD.has much to do with the amount of formal education79.Both specialists and generalists, Donohoe and Clancy contend, could do a better job of .A.taking advantage of the otherB.avoiding as much malpractice as possibleC.putting the latest knowledge into practicecating the public to their consciousness of health80.Donohoe is trying to shift our attention to .A.better communication and cooperation between generalists and specialistsB.the real nature of specialist and generalist care, respectivelyC.the similarities between generalist and specialist careD.the declining health of AmericansPassage FiveChildren are spending an increasing amount of time using computers. Computers are now found in most classrooms,and in the majority of homes, almost always with internet accepts. However,many studies of children’s use of computers show that there are possible negative effects. This essay will explain the possible negative effects of computer use on children, focusing on the effects on family and peer relationships and the increased tendency towards violent behavior.Computer use may negatively affect the social relationship between children and their parents. Because children spend so much time on computers, they often know more about advanced computer use than their parents, According to Subrahmanyam and his colleagues(2022) this often leads to a role reversal, where the child becomes a teacher to the parent. In other words, it is often the case that a highly computer literate teenager will teach their parents how to use the more complex functions of computer technology. This can lead to a reduction in parental authority. Moreover, with the anonymity of online communication, computer users do not know if they are talking to a child or an adult, so all users are treated eually (Subrahmanyam et al, 2022). Children may then expect the same euality in real life, further contributing to a breakdown in the parent-children relationship (Subrahmanyam et al, 200l).computers are more likely to be used in isolation by children, they spend little time interacting with their peers (Shields & Behrman, 2022). As a result, children may not develop the social skills they need, or be able to maintain friendships in the real world (Subrahmanyam et al, 2022). With the very extended computer use, this isolation from the real world can lead to loneliness and even depression(Shields & Behrman, 2022).A disturbing possible effect of computer use on children is the link between computer games and violence. Current research has already documented a strong link between violent films and television and aggressive behavior in children, so it is reasonable to believe that a similar link will be found between violent behavior in children and violence in computer games ( Subrahmanyam et al, 200l). However, as Shields Behrman (200l) points out, it is important to note that although the games may affect all children, children who prefer violent games could be most affected.In conclusion, using a computer, particularly for extended periods, may affect the parent-children relationship in families. It could also result in children not learning the social skills they need to interact with peers and maintain friendships. Moreover, it seems likely that playing violent computer games is linked to violence in children. Although the research is not conclusive,it appears tha t extended use of computers could have a negative effect on children’s social development.8l. From the very beginning, the author is trying to draw out attention toA.crimes on rise at schoolB.a decline in family valueC.the negative effects of chil dren’s overuse of computerD.the increasing number of investigations on education82.Which is the best reason for the reduction of parental authority according to the passageA.Children become teachers to their parents.B.Parents are fossilized in new technology.C.Children expect for an eual status with their parents.D.Parents’ roles are being shrunk by the computer.83.What does Shield Behrman imply in the passageA.Children greatly value the friendship with their peers.B.Children are doomed to suffer depression by using computer.C.Children will in no circumstances be affected by violent games.D.Children’s inclination to aggression may derive from violent games.84.Which of the following is NOT mentioned as the negative result of playing computer games inthe passageA. A lack of social communication.B. Increasing violent performance.C. A decline in intelligence.D. A breakdown in family relationship.85.Where the passage might be taken from。

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 theANSWER SHEET.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 for your 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 rather than negative effect.According to BBC news, the Florida Alzheimer’s Disease Research Center conducted a study on96 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-hour periods 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 cognitive abilities 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 brains and 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. identicalB. beneficialC. preferableD. susceptible59. A. effortB. methodC. huntD. account60. A. do affectB. did affectC. is affectingD. could have affectedPart 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 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. When I 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 oftheir trade, 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.C. laboratory 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’s inaccurate orconfusing, even more so. This is a problem for anyone trying to spend or invest in an environmentally sustainable way. Investors are barraged with indexes purporting to describe companies’ 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. “The confusion” at the beginning of the 2nd 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 cases ________.A. 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.C. Information 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 advocates point 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 is preliminary 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 theboundaries, 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. This report 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 that the 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 report’s 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 FiveHumanity has passed a milestone: more people live in cities than in rural areas. The current rate of urbanization is unprecedented in our history. In 1950, only 29% of。

For each blank, there are four choices marked A, B, C and 0 on the right side. Choose the best answer and mark the letter of your choice on the ANSWER SHEET.A mother who is suffering from cancer can pass on the disease to her unborn child in extremely rare cases, 51 a new case report published in PNAS this week.According to researchers in Japan and at the Institute for Cancer Research in Sutton, UK, a Japanese mother had been diagnosed with leukemia a few weeks after giving birth，52 tumors were discovered in her daughter's cheek and lung when she was 11 months old. Genetic analysis showed that the baby's cancer cells had the same mutation as the cancer cells of the mother But the cancer cells contained no DNA whatsoever from the father，53 would be expected if she had inherited the cancer from conception. That suggests the cancer cell made it into the unborn child 's body across the placental barrier.The Guardian claimed this to be the first 54 case of cells crossing the placental barrier But this is not the case -- microchimerism ，55 cells are exchanged between a mother and her unborn child, is thought to be quite common, with some cells thought to pass from fetus to mother in about 50 to 75 percent of cases and to go the other way about half 56 .As the BBC pointed out, the greater 57 in cancer transmission from mother to fetus had been how cancer cells that have slipped through the placental barrier could survive in the fetus without being killed by its immune system. The answer in this case at least, lies in a second mutation of the cancercells, which led to the 58 of the specific features that would have allowed the fetal immune system to detect the cells as foreign. As a result, no attack against the invaders was launched.59 according to the researchers there is little reason for concern of "cancer danger" Only 17 probable cases have been reported worldwide and the combined 60 of cancer cells both passing the placental barrier and having the right mutation to evade the baby's immune system is extremely low51 A. suggests B. suggestingC. having suggestedD. suggested52.

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 SHEETPassage OneThe American Society of Clinical Oncology wrapped its annual conference this week, going through the usual motions of presenting a lot of drugs that offer some added quality or extension of life to those suffering from a variety of as-yet incurable diseases. But buried deep in an AP story are a couple of promising headlines that seems worthy of more thorough review, including one treatment study where 100 percent of patients saw their cancer diminish by half.First of all, it seems pharmaceutical companies are moving away from the main cost-effective one-size-fits-all approach to drug development and embracing the long cancer treatments, engineering drugs that only work for a small percentage of patients but work very effectively within that group.Pfizer announced that one such drug it's pushing into late-stage testing is target for 4% of lung cancer patients. But more than 90% of that tiny cohort responded to the drug initial tests, and 9 out of ten is getting pretty close to the ideal ten out of ten. By gearing toward more boutique treatments rather than broad umbrella pharmaceuticals that try to fit for everyone it seems cancer researchers are making some headway. But how can we close the gap on that remaining ten percent?Ask Takeda Pharmaceutical and Celgene, two drug makers who put aside competitive interests to test a novel combination of their treatments. In a test of 66 patients with the blood disease multiple myeloma, a full 100 percent of the subjects saw their cancer reduced by half. Needless to say, a 100 percent response to a cancer drug (or in this case a drug cocktail) is more or less unheard of. Moreover, this combination never would've been two competing companies hadn't sat down and put their heads togetherAre there more potentially effective drug combos out there separated by competitive interest and proprietary information? Who's to say, but it seems like with the amount of money and research being pumped into cancer drug development, the outcome pretty good. And if researchers can start pushing more of their response numbers toward 100 percent, we can more easily start talking about oncology's favorite four-letter word: cure.61 Which of the following can be the best title for the passage?A. Competition and CooperationB. Two Competing Pharmaceutical CompaniesC. The Promising Future of PharmaceuticalsD. Encouraging News: a 100% Response to a Cancer Drug62. In cancer drug development, according to the passage, the pharmaceuticals nowA. are adopting the cost-effective one-size-fits-all approachB. are moving towards individualized and targeted treatmentsC. are investing the lion's shares of their moneyD. care only about their profits63. From the encouraging advance by the two companies, we can infer thatA. the development can be ascribed to their joint efforts and collaborationB. it was their competition that resulted in the accomplishmentC. other pharmaceuticals will join them in the researchD. the future cancer treatment can be nothing but cocktail therapy64. From the last paragraph it can be inferred that the answer to the question _A. is nowhere to be foundB. can drive one crazyC. can be multipleD. is conditional65. The tone of the author of this passage seems to beA. neutralB. criticalC. negativeD. optimistPassage TwoLiver disease is the 12th -leading cause of death in the U.S., chiefly because once it's determined that a patient needs a new liver it's very difficult to get one. Even in case where a suitable donor match is found, there's guarantee a transplant will be successful. But researchers at Massachusetts General Hospital have taken a huge step toward building functioning livers in the lab, successfully transplanting culture-gown livers into rats.The livers aren't grown from scratch, but rather within the infrastructure of a donor liver. The liver cells in the donor organ are washed out with a detergent that gently strips away the liver cells, leaving behind a biological scaffold of proteins and extracellular architecture that is very hard to duplicate synthetically.With all of that complicated infrastructure already in place, the researchers then seeded the scaffold (支架) with liver cells isolated from healthy livers, as well as some special endothelial cells to line the bold vessels. Once repopulated with healthy cells, these livers lived in culture for 10 days.The team also transplanted some two-day-old recellularized livers back into rats, where they continued to thrive for eight hours while connected into the rats' vascular systems. However the current method isn't perfect and cannot seem to repopulate the blood vessels quite densely enough and the transplanted livers can't keep functioning for more than about 24 hours (hence the eight-hour maximum for the rat transplant)But the initial successes are promising, and the team thinks they can overcome the blood vessel problem and get fully functioning livers into rats within two years. It still might be a decade before the tech hits the clinic, but if nothing goes horribly wrong-and especially if stem-cell research establishes a reliable way to create health liver cells from the every patients who need transplants-lab-generated livers that are perfect matches for their recipients could become a reality.66. It can be inferred from the passage that the animal model was mainly intended toA. investigate the possibility of growing blood vessels in the labB. explore the unknown functions of the human liverC. reduce the incidence of liver disease in the U.S.D. address the source of liver transplants67 What does the author mean when he says that the livers aren't grown from scratch?A. The making of a biological scaffold of proteins and extracellular architecture.B. A huge step toward building functioning livers in the lab.C. The building of the infrastructure of a donor liverD. Growing liver cells in the donor organ68. The biological scaffold was not put into the culture in the lab untilA. duplicated syntheticallyB. isolated from the healthy liverC. repopulated with the healthy cellsD. the addition of some man-made blood vessels69. What seems to be the problem in the planted liver?A. The rats as wrong recipients.B. The time point of the transplantation .C. The short period of the recellularization.D. The insufficient repopulation of the blood vessels.70. The research team holds high hopes ofA. creating lab-generated livers for patients within two yearsB. the timetable for generating human livers in the labC. stem-cell research as the future of medicineD. building a fully functioning liver into ratsPassage ThreePatients whose eyes have suffered heat or chemical burns typically experience severe damage to the cornea--the thin, transparent front of the eye that refracts light and contributes most of the eye's focusing ability. In along-term study, Italian researchers use stem cells taken from the limbus, the border between the cornea and the white of the eye, to cultivate a graft of healthy cells in a lab to help restore vision in eyes. During the 10-years study, the researchers implanted the healthy stem cells into the damaged cornea in 113 eyes of 112 patients. The treatment was fully successful in more than 75 percent of the patients, and partially successful in 13 percent. Moreover, the restored vision remained stable over 10 years. Success was defined as an absence of all symptoms and permanent restoration of the cornea.Treatment outcome was initially assessed at one year, with up to 10 years of follow-up evaluations. The procedure was even successful in several patients whose burn injuries had occurred years earlier and who had already undergone surgery.Current treatment for burned eyes involves taking stem cells from a patient's healthy eye, or from the eyes of another person, and transferring them to the burned eye. The new procedure, however stimulates the limbal stem cells from the patient's own eye to reproduce in a lab culture. Several types of treatments using stem cells have proven successful in restoring blindness, but the long-term effectiveness shown here is significant. The treatment is only for blindness caused by damage to the cornea; it is not effective for repairing damaged retinas or optic nerves.Chemical eye burns often occur in the workplace, but can also happen due to mishaps involving household cleaning products and automobile batteries.The results of the study, based at Italy's University of Modena and Reggio Emilia, were published in the June 23 online issue of the New England Journal of Medicine.71 What is the main idea of this passage?A. Stem cells can help restore vision in the eyes blinded by burns.B. The vision in the eyes blinded by burns for 10 years can be restored.C. The restored vision of the burned eyes treated with stem cells can last for 10 years.D. The burned eyes can only be treated with stem cells from other healthy persons.72. The Italian technique reported in this passageA. can repair damaged retinasB. is able to treat damaged optic nervesC. is especially effective for burn injuries in the eyes already treated surgicallyD. shows a long-term effectiveness for blindness in vision caused by damage to cornea73. Which of the following is NOT mentioned about eye burns?A. The places in which people work.B. The accidents that involve using household cleaning products.C. The mishaps that involved vehicles batteries.D. The disasters caused by battery explosion at home.74. What is one of the requirements for the current approach?A. The stem cells taken from a healthy eye.B. The patient physically healthy.C. The damaged eye with partial vision.D. The blindness due to damaged optic nerves.75. Which of the following words can best describe the author's attitude towards thenew method?A. Sarcastic.B. Indifferent.C. Critical.D. PositivePassage FourHere is a charming statistic: divide the US by race, sex and county of residence, and differences in average life expectancy across the various groups can exceed 30 years. The most disadvantaged look like denizens of a poor African country: a boy born on a Native American reservation in Jackson County, South Dakota, for example, will be lucky to reach his 60th birthday. A typical child in Senegal can expect to live longer than that.America is not alone in this respect. While the picture is extreme in other rich nations, health inequalities based on race, sex and class exist in most societies--and are only partly explained by access to healthcare.But fresh insights and solutions may soon be at hand. An innovative project in Chicago to unite sociology and biology is blazing the trail (开创)，after discovering that social isolation and fear of crime can help to explain the alarmingly high death rate from breast cancer among the city's black women. Living in these conditions seems to make tumors more aggressive by changing gene activity, so that cancer cells can use nutrients more effectively.We are already familiar with the lethal effect of stress on people clinging to the bottom rungs of the societal ladder, thanks to pioneering studies of British civil servants conducted by Michael Marmot of University College London.What's exciting about the Chicago project is that it both probes the mechanisms involved in a specific disease and suggests precise remedies. There are drugs that may stave tumors of nutrients and community coordinators could be employed to help reduce social isolation .Encouraged by the US National Institutes of Health, similar projects are springing up to study other pockets of poor health, in populations ranging from urban black men to white poor women in rural Appalachia.To realize the full potential of such projects, biologists and sociologists will have to start treating one other with a new respect and learn how to collaborate outside their comfort zones. Too many biomedical researchers still take the arrogant view that sociology is a "soft science" with little that's serious to say about health. And too many sociologists reject any biological angle--fearing that their expertise will be swept aside and that this approach will be used to bolster discredited theories of eugenics, or crude race-based medicineIt's time to drop these outdated attitudes and work together for the good of society's most deprived members. More important, it's time to use this fusion of biology and sociology to inform public policy. This endeavor has huge implications, not least in cutting the wide health gaps between blacks and whites, rich and poor76. As shown in the 1st paragraph, the shaming statistic reflects -A. injustice everywhereB. racial discriminationC. a growing life spanD. health inequalities77. Which of the following can have a negative impact on health according to the Chicago-based project?A. Where to live.B. Which race to belong toC. How to adjust environmentally.D. What medical problem to suffer.78. The Chicago-based project focuses its management onA. a particular medical problem and its related social issueB. racial discrimination and its related social problemsC. the social ladder and its related medical conditionsD. a specific disease and its medical treatment78. The Chicago-based project focuses its management onA. a particular medical problem and its related social issueB. racial discrimination and its related social problemsC. the social ladder and its related medical conditionsD. a specific disease and its medical treatment79.

The antibodies were discovered in the cells of a60-year-old African-American gay man whose body produced them naturally. One antibody in particular is substantially different from its precursors, the Science study says.The antibodies could be tried as a treatment for people already infected with HIV, the WSJreports. At the very, least, they might boost the efficacy of current antiretroviral drugs.It is welcome news for the 33 million people the United Nations estimated were living with AIDS at the end of 2008.The WSJ outlines the painstaking method the team used to find the antibody amidthe cells of the African-American man, known as Donor 45. First they designed a probe that looks just like a spot on a particular molecule on the cells that HIV infects. Theyused the probe to attract only the antibodies that efficiently attack that spot. They screened 25 million of Donor 45's cell to find just 12 cells that produced the antibodiesScientists have already discovered plenty of antibodies that either don't work at all or only work on a couple of HIV strains. Last year marked the first time that researchers found "broadly neutralizing antibodies," which knock out many H IV strains. But none of those antibodies neutralized more than about 40 percent of them the WSJ says. The newest antibody, at 91 percent neutralization, is a marked improvement.Still, more work needs to be done to ensure the antibodies would activate the immune system to produce natural defenses against AIDS, the study authors say. They suggest there test methods that blend the three new antibodies together--in raw form to prevent transmission of the virus, such as from mother to child; in a microbicide gel that women or gay men could use before sex to prevent infection; or as a treatment for HIV/AIDS, combined with antiretroviral drug.If the scientists can find the right way to stimulate production of the antibodies, theythink most people could produce then , the WSJ says.81 We can learn from the beginning ofthe passage that_A. a newly discovered antibody defeats 91 % of the H IV strainsB. a new antiretroviral drug has just come on the marketC. American researchers have developed a new vaccine for HIVD. the African-American gay man was cured of his HIV infection82. What is the implication of the antibodies discovered in the cells of the African-American gay man?。

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 SHEETPassage OneThe American Society of Clinical Oncology wrapped its annual conference this week, going through the usual motions of presenting a lot of drugs that offer some added quality or extension of life to those suffering from a variety of as-yet incurable diseases. But buried deep in an AP story are a couple of promising headlines that seems worthy of more thorough review, including one treatment study where 100 percent of patients saw their cancer diminish by half.First of all, it seems pharmaceutical companies are moving away from the main cost-effective one-size-fits-all approach to drug development and embracing the long cancer treatments, engineering drugs that only work for a small percentage of patients but work very effectively within that group.Pfizer announced that one such drug it's pushing into late-stage testing is target for 4% of lung cancer patients. But more than 90% of that tiny cohort responded to the drug initial tests, and 9 out of ten is getting pretty close to the ideal ten out of ten. By gearing toward more boutique treatments rather than broad umbrella pharmaceuticals that try to fit for everyone it seems cancer researchers are making some headway. But how can we close the gap on that remaining ten percentAsk Takeda Pharmaceutical and Celgene, two drug makers who put aside competitive interests to test a novel combination of their treatments. In a test of 66 patients with the blood disease multiple myeloma, a full 100 percent of the subjects saw their cancer reduced by half. Needless to say, a 100 percent response to a cancer drug or in this case a drug cocktail is more or less unheard of. Moreover, this combination never would've been two competing companies hadn't sat down and put their heads togetherAre there more potentially effective drug combos out there separated by competitive interest and proprietary informationWho's to say, but it seems like with the amount of money and research being pumped into cancer drug development, the outcome pretty good. And if researchers can start pushing more of their response numbers toward 100 percent, we can more easily start talking about oncology's favorite four-letter word: cure.61 Which of the following can be the best title for the passageA. Competition and CooperationB. Two Competing Pharmaceutical CompaniesC. The Promising Future of PharmaceuticalsD. Encouraging News: a 100% Response to a Cancer Drug62. In cancer drug development, according to the passage, the pharmaceuticals nowA. are adopting the cost-effective one-size-fits-all approachB. are moving towards individualized and targeted treatmentsC. are investing the lion's shares of their moneyD. care only about their profits63. From the encouraging advance by the two companies, we can infer thatA. the development can be ascribed to their joint efforts and collaborationB. it was their competition that resulted in the accomplishmentC. other pharmaceuticals will join them in the researchD. the future cancer treatment can be nothing but cocktail therapy64. From the last paragraph it can be inferred that the answer to the question_ A. is nowhere to be foundB. can drive one crazyC. can be multipleD. is conditional65. The tone of the author of this passage seems to beA. neutralB. criticalC. negativeD. optimistPassage TwoLiver disease is the 12th -leading cause of death in the ., chiefly because once it's determined that a patient needs a new liver it's very difficult to get one. Even in case where a suitable donor match is found, there's guaranteea transplant will be successful. But researchers at Massachusetts General Hospital have taken a huge step toward building functioning livers in the lab, successfully transplanting culture-gown livers into rats.The livers aren't grown from scratch, but rather within the infrastructureof a donor liver. The liver cells in the donor organ are washed out with a detergent that gently strips away the liver cells, leaving behind a biological scaffold of proteins and extracellular architecture that is very hard to duplicate synthetically.With all of that complicated infrastructure already in place, the researchers then seeded the scaffold 支架 with liver cells isolated from healthy livers, as well as some special endothelial cells to line the bold vessels. Once repopulated with healthy cells, these livers lived in culture for 10 days.The team also transplanted some two-day-old recellularized livers back into rats, where they continued to thrive for eight hours while connected into the rats' vascular systems. However the current method isn't perfect and cannot seem to repopulate the blood vessels quite densely enough and the transplanted livers can't keep functioning for more than about 24 hours hence the eight-hour maximum for the rat transplantBut the initial successes are promising, and the team thinks they can overcome the blood vessel problem and get fully functioning livers into rats within two years. It still might be a decade before the tech hits the clinic,but if nothing goes horribly wrong-and especially if stem-cell research establishes a reliable way to create health liver cells from the every patients who need transplants-lab-generated livers that are perfect matches for their recipients could become a reality.66. It can be inferred from the passage that the animal model was mainly intendedtoA. investigate the possibility of growing blood vessels in the labB. explore the unknown functions of the human liverC. reduce the incidence of liver disease in the .D. address the source of liver transplants67 What does the author mean when he says that the livers aren't grown from scratchA. The making of a biological scaffold of proteins and extracellular architecture.B. A huge step toward building functioning livers in the lab.C. The building of the infrastructure of a donor liverD. Growing liver cells in the donor organ68. The biological scaffold was not put into the culture in the lab untilA. duplicated syntheticallyB. isolated from the healthy liverC. repopulated with the healthy cellsD. the addition of some man-made blood vessels69. What seems to be the problem in the planted liverA. The rats as wrong recipients.B. The time point of the transplantation .C. The short period of the recellularization.D. The insufficient repopulation of the blood vessels.70. The research team holds high hopes ofA. creating lab-generated livers for patients within two yearsB. the timetable for generating human livers in the labC. stem-cell research as the future of medicineD. building a fully functioning liver into ratsPassage ThreePatients whose eyes have suffered heat or chemical burns typically experience severe damage to the cornea--the thin, transparent front of the eye that refracts light and contributes most of the eye's focusing ability. In a long-term study, Italian researchers use stem cells taken from the limbus, the border between the cornea and the white of the eye, to cultivate a graft of healthy cells in a lab to help restore vision in eyes. During the 10-years study,the researchers implanted the healthy stem cells into the damaged cornea in 113 eyes of 112 patients. The treatment was fully successful in more than 75 percent of the patients, and partially successful in 13 percent. Moreover, therestored vision remained stable over 10 years. Success was defined as an absence of all symptoms and permanent restoration of the cornea.Treatment outcome was initially assessed at one year, with up to 10 years of follow-up evaluations. The procedure was even successful in several patients whose burn injuries had occurred years earlier and who had already undergone surgery.Current treatment for burned eyes involves taking stem cells from a patient's healthy eye, or from the eyes of another person, and transferring them to the burned eye. The new procedure, however stimulates the limbal stem cells from the patient's own eye to reproduce in a lab culture. Several types of treatments using stem cells have proven successful in restoring blindness, but the long-term effectiveness shown here is significant. The treatment is only for blindness caused by damage to the cornea; it is not effective for repairing damaged retinas or optic nerves.Chemical eye burns often occur in the workplace, but can also happen due to mishaps involving household cleaning products and automobile batteries.The results of the study, based at Italy's University of Modena and Reggio Emilia, were published in the June 23 online issue of the New England Journal of Medicine.71 What is the main idea of this passageA. Stem cells can help restore vision in the eyes blinded by burns.B. The vision in the eyes blinded by burns for 10 years can be restored.C. The restored vision of the burned eyes treated with stem cells can last for10 years.D. The burned eyes can only be treated with stem cells from other healthy persons.72. The Italian technique reported in this passageA. can repair damaged retinasB. is able to treat damaged optic nervesC. is especially effective for burn injuries in the eyes already treated surgicallyD. shows a long-term effectiveness for blindness in vision caused by damage to cornea73. Which of the following is NOT mentioned about eye burnsA. The places in which people work.B. The accidents that involve using household cleaning products.C. The mishaps that involved vehicles batteries.D. The disasters caused by battery explosion at home.74. What is one of the requirements for the current approachA. The stem cells taken from a healthy eye.B. The patient physically healthy.C. The damaged eye with partial vision.D. The blindness due to damaged optic nerves.75. Which of the following words can best describe the author's attitude towards thenew methodA. Sarcastic.B. Indifferent.C. Critical.D. PositivePassage FourHere is a charming statistic: divide the US by race, sex and county of residence, and differences in average life expectancy across the various groups can exceed 30 years. The most disadvantaged look like denizens of a poor African country: a boy born on a Native American reservation in Jackson County, South Dakota, for example, will be lucky to reach his 60th birthday. A typical child in Senegal can expect to live longer than that.America is not alone in this respect. While the picture is extreme in other rich nations, health inequalities based on race, sex and class exist in most societies--and are only partly explained by access to healthcare.But fresh insights and solutions may soon be at hand. An innovative project in Chicago to unite sociology and biology is blazing the trail 开创, after discovering that social isolation and fear of crime can help to explain the alarmingly high death rate from breast cancer among the city's black women. Living in these conditions seems to make tumors more aggressive by changing gene activity, so that cancer cells can use nutrients more effectively.We are already familiar with the lethal effect of stress on people clinging to the bottom rungs of the societal ladder, thanks to pioneering studies of British civil servants conducted by Michael Marmot of University College London. What's exciting about the Chicago project is that it both probes the mechanisms involved in a specific disease and suggests precise remedies. There are drugs that may stave tumors of nutrients and community coordinators could be employed to help reduce social isolation .Encouraged by the US National Institutes of Health, similar projects are springing up to study other pockets of poor health, in populations ranging from urban black men to white poor women in rural Appalachia.To realize the full potential of such projects, biologists and sociologists will have to start treating one other with a new respect and learn how to collaborate outside their comfort zones. Too many biomedical researchers still take the arrogant view that sociology is a "soft science" with little that's serious to say about health. And too many sociologists reject any biological angle--fearing that their expertise will be swept aside and that this approach will be used to bolster discredited theories of eugenics, or crude race-based medicineIt's time to drop these outdated attitudes and work together for the good of society's most deprived members. More important, it's time to use this fusion of biology and sociology to inform public policy. This endeavor has huge implications, not least in cutting the wide health gaps between blacks and whites, rich and poor76. As shown in the 1st paragraph, the shaming statistic reflects -A. injustice everywhereB. racial discriminationC. a growing life spanD. health inequalities77. Which of the following can have a negative impact on health according to the Chicago-based projectA. Where to live.B. Which race to belong toC. How to adjust environmentally.D. What medical problem to suffer.78. The Chicago-based project focuses its management onA. a particular medical problem and its related social issueB. racial discrimination and its related social problemsC. the social ladder and its related medical conditionsD. a specific disease and its medical treatment78. The Chicago-based project focuses its management onA. a particular medical problem and its related social issueB. racial discrimination and its related social problemsC. the social ladder and its related medical conditionsD. a specific disease and its medical treatment79. Which of the following can most probably neglected by sociologistsA. The racial perspective.B. The environmental aspect.C. The biological dimension.D. The psychological angel.80. The author is a big fan ofA. the combination of a traditional and new way of thinking in promoting healthB. the integration of biologists and sociologists to reduce health inequalitiesC. the mutual understanding and respect between racesD. public education and health promotionPassage FiveAmerican researchers are working on three antibodies that many mark a new step on the path toward an HIV vaccine, according to a report published online Thursday, July 8, 2010, in the journal Science.One of the antibodies suppresses 91 percent of HIV strains, more than any AIDS antibody ever discovered , according to a report on the findings published in the WallStreet Journal. The antibodies were discovered in the cells of a 60-year-old African-American gay man whose body produced them naturally. One antibody in particular is substantially different from its precursors, the Science study says.The antibodies could be tried as a treatment for people already infected with HIV, the WSJreports. At the very, least, they might boost the efficacy of current antiretroviral drugs.It is welcome news for the 33 million people the United Nations estimated were living with AIDS at the end of 2008.The WSJ outlines the painstaking method the team used to find the antibody amidthe cells of the African-American man, known as Donor 45. First they designed a probe that looks just like a spot on a particular molecule on the cells that HIV infects. Theyused the probe to attract only the antibodies that efficiently attack that spot. They screened 25 million of Donor 45's cell to find just 12 cells that produced the antibodies。
