A mother who is suffering from cancer can pass on the disease to her unborn child in extremely rare cases,51a 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 was11months 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 first54case of cells crossing the placental barrier. But this is not the case--microchimerism,55cells 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 about50to75per cent of cases and to go the other way about half56_.
As the BBC pointed out,the greater57in 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 cancer cells,which led to the58of 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". Only17probable cases have been reported worldwide and the combined60of cancer cells both passing the placental barrier and having the right mutation to evade the baby's immune system is extremely low.
51. A.suggests B.suggesting C.having suggested D.suggested
52. A.since B.although C.whereas D.when
53. A.what B.whom C.who D.as
54. A.predicted B.notorious C.proven D.detailed
55. A.where B.when C.if D.whatever
56. A.as many B.as much C.as well D.as often
57. A.threat B.puzzle C.obstacle D.dilemma

Part IV Reading Comprehension(30%)
Directions:In this part there are six passages,each of which is followed by five questions. For each question there are four possible answers marked A,B,C,and D.Choose the best answer and mark the letter of your choice on the ANSWER SHEET.
Passage One
The 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 where100percent 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 for4%of lung cancer patients.But more than90%of that tiny cohort responded to the drug initial tests, and9out 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 of66patients with the blood disease multiple myeloma,a full100percent of the subjects saw their cancer reduced by half. Needless to say,a100percent 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 toward100percent,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?
https://www.doczj.com/doc/9b8404388.html,petition and Cooperation
B.Two Competing Pharmaceutical Companies

A.the development can be ascribed to their joint efforts and collaboration
B.it was their competition that resulted in the accomplishment
C.other pharmaceuticals will join them in the research
D.the future cancer treatment can be nothing but cocktail therapy
64.From the last paragraph it can be inferred that the answer to the question______.
A.is nowhere to be found
B.can drive one crazy
C.can be multiple
D.is conditional
65.The tone of the author of this passage seems to be_______.
A.neutral
B.critical
C.negative
D.optimist
Passage Two
Liver disease is the12th-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-grown 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 for10days.
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 about24 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 lab
B.explore the unknown functions of the human liver
C.reduce the incidence of liver disease in the U.S.
D.address the source of liver transplants
67.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 liven
D.Growing liver cells in the donor organ.
68.The biological scaffold was not put into the culture in the lab until______.
A.duplicated synthetically
B.isolated from the healthy liver
C.repopulated with the healthy cells
D.the addition of some man-made blood vessels
69.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 of_______.
A.creating lab-generated livers for patients within two years
B.the timetable for generating human livers in the lab
C.stem-cell research as the future of medicine
D.building a fully functioning liver into rats
Passage Three
Patients whose eyes have suffered heat or chemical bums 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 the10-years study,the researchers implanted the healthy stem cells into the damaged cornea in113eyes of112patients.The treatment was fully successful in more than75percent of the patients,and partially successful in13percent.Moreover,the restored vision remained stable over10years.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 to10years of follow-up evaluations.The procedure was even successful n several patients whose bum 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 bums 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 June23online 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 bums.
B.The vision in the eyes blinded by bums for10years can be restored.
C.The restored vision of the burned eyes treated with stem cells can last for10years.
D.The burned eyes can only be treated with stem cells from other healthy persons.
72.The Italian technique reported in this passage______.
A.can repair damaged retinas
B.is able to treat damaged optic nerves
C.is especially effective for bum injuries in the eyes already treated surgically
D.shows a long-term effectiveness for blindness in vision caused by damage to cornea
73.Which of the following is NOT mentioned about eye bums?
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 the new method?
A.Sarcastic.
B.Indifferent.
C.Critical.
D.Positive.
Passage Four
Here 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 exceed30years.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 his60th 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 that it both probes the mechanisms invlilved 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 medicine.
It'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 poor.
76.As shown in the1st paragraph,the shaming statistic reflects________.
A.injustice everywhere
B.racial discrimination
C.a growing life span
D.health inequalities
77.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 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 issue
B.racial discrimination and its related social problems
C.the social ladder and its related medical conditions
D.a specific disease and its medical treatment
78.The Chicago-based project focuses its management on_______.
A.a particular medical problem and its related social issue
B.racial discrimination and its related social problems
C.the social ladder and its related medical conditions
D.a specific disease and its medical treatment
79.Which of the following can most probably neglected by sociologists?

C.The biological dimension.
D.The psychological angel.
80.The author is a big fan of________.

B.the integration of biologists and sociologists to reduce health inequalities
C.the mutual understanding and respect between races
D.public education and health promotion
Passage Five
American 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,July8,2010,in the journal Science.
One of the antibodies suppresses91percent 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 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 WSJ reports.At the very least,they might boost the efficacy of current antiretroviral drugs.
It is welcome news for the33million people the United Nations estimated were living with AIDS at the end of2008.
The WSJ outlines the painstaking method the team used to find the antibody amid the cells of the African-American man,known as Donor45.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 screened25million of Donor 45's cell to find just12cells that produced the antibodies.
Scientists have already discovered plenty of antibodies that either don't work at all or only work on a couple of HIV https://www.doczj.com/doc/9b8404388.html,st 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 about40percent of them,the WSJ says.The newest antibody, at91percent 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 defeats91%of the HIV strains
B.a new antiretroviral drug has just come on the market
C.American researchers have developed a new vaccine for HIV
D.the African-American gay man was cured of his HIV infection
82.What is the implication of the antibodies discovered in the cells of the African-American gay man?
A.They can cure the33million 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 quick diagnosis of an HIV infection.
83.The newest antibody found in Donor45reflects a dramatic advance in terms of_______.
A.pathology
B.pharmacology
C.HIV neutralization
D.HIV epidemiology
84.According to the study authors,the three test methods are intended to______.
A.advance the technology in condom production to prevent HIV infection
B.facilitate the natural immune defense against AIDS
C.Develop more effective antiretroviral drugs
D.Develop more effective antiretroviral drugs
85.The passage is most likely______.
A.a news report
B.a paper in Science
C.an excerpt from an Immunology Textbook
D.an episode in a science fiction novel
Passage Six
Whitening the world's roofs would offset the emissions of the world's cars for20years, according to a new study from Lawrence Berkeley National Laboratory.Overall,installing lighter-colored roofs and pavement can cancel the heat effect of two years of global carbon dioxide emissions,Berkeley Lab says.It's the first roof-cooling study to use a global model to examine the issue.
Lightening up roofs and pavement can offset57billion metric tons of carbon dioxide, about double the amount the world emitted in2006,the study found.It was published in the journal Environmental Research Letters.
Researchers used a conservative estimate of increased albedo,or solar reflection, suggesting that purely white roofs would be even better.They increased the albedo of all roof by0.25and pavement by0.15.That means a black roof,which has an albedo of zero,would only need to be replaced by a roof of a cooler color--which might be more feasible to implement than a snowy white roof.Berkeley Lab says.
The researchers extrapolated a roof's CO2offset over its average lifespan.If all roofs were converted to white or cool colors,they would offset about24gigatons(24billion metric tons)of CO2,but only once.But assuming roofs last about20years,the researchers came up with1.2gigatons per year.That equates to offsetting the emissions of roughly300million cars, all the in the world,for20years.
Pavement and roofs cover50to65percent of urban areas and cause a heat-island effect because they absorb so much heat.That's why cities are significantly warmer than surrounding rural areas.This effect makes it harder and therefore more expensive--to keep buildings cool in the summer.Winds also move the heat into the atmosphere,causing a regional warming effect.
Energy secretary Steven Chu,a Nobel laurete in physics(and former Berkeley Lab director),has advocated white roofs for years.He put his words into actions by directing all Energy Department offices to install white roofs.All newly installed roofs will be white,and black roofs might be replaced when it is cost-effective over the lifetime of the roof.
"Cool roofs are one of the quickest and lowest-cost ways we can reduce our global carbon emissions and begin the hard work of slowing climate change."He said in a statement.
86.Which of the following can be the best title for the passage?

D.are supposed to be placed by snowy white ones
88.If they are converted to white or cooler colors,all roofs in the world in their lifetime __________.
A.can absorb1.2gigatons of CO2a year
B.could serve as300million cars in terms of emission
C.would offset the emissions from300million cars
D.would offset about24gigatons of CO2as emitted from the cars
89.According to the passage,it is hard and expensive to keep the urban buildings cool because of______.
A.the heat-island effect
B.the lack of seasonal winds
C.the local unique weather
D.the fast urban shrinkage
90.Energy Secretary Steven Chu implies that_______.
A.nothing could be more effective in cooling global warming than method he has advocated
B.the method in question still needs to be justified in the future

医学考博英语翻译习题 An AIDS Mystery Solved (1) About 15 years ago， a well-meaning man donated blood to the Red Cross in Sydney，Australia，not knowing he has been exposed to HIV-1，the virus that causes AIDS. Much later，public-health officials learned that some of the people who got transfusions? containing his blood had become infected with the same virus; presumably they were almost sure to die. But as six years stretched to 10，then to 14，the anxiety of health officials gave way to astonishment. Although two of the recipients have died from other causes，not one of the seven people known to have received transfusions of the man’s contaminated blood has come down with AIDS. More telling still，the donor，a sexually active homosexual，is also healthy. In fact his immune system remains as robust as if he had never tangled with HIV at all. What could explain such unexpected good fortune? (2) A team of Australian scientists has finally solved the mystery. The virus that the donor contracted and then passed on，the team reported last week in the journal Science. contains flaws in its genetic script that appear to have rendered it innocuous?. “Not only have the recipients and the donor not progressed to disease for 15 years，”marvels molecular biologist Nicholas Deacon of Australia’s Macfarlane Burnet Centre for Medical Re-search，“but the prediction is that they never will.”Deacon speculates that this “impotent”HIV may even be a natural inoculant? that protects its carriers against more virulent strains? of the virus，much as infection with cowpox warded off smallpox in 18th-century milkmaids. (3) If this ______ proves right，it will mark a milestone in the battle to contain the late-20th century’s most terrible epidemic. For in addition to explaining why this small group of people infected with HIV has not become sick，the discovery of a viral strain that works like a vaccine would have far-reaching implications. “What these results suggest，”says Dr. Barney Graham of Tennessee’s Vanderbilt University，“is that HIV is vulnerable and that it is possible to stimulate effective immunity against it.” (4) The strain of HIV that popped up? in Sydney intrigues scientists because it contains striking abnormalities in a gene that is believed to stimulate viral duplication. In fact，the virus is missing so much of this particular gene —known as nef，for negative factor —that it is hard to imagine how the gene could perform any useful function. And sure enough，while the Sydney virus retains the ability to infect T cells —white blood cells that are critical to the immune system’s ability to ward off infection —it makes so few copies of itself that the most powerful molecular tools can barely detect its presence. Some of the infected Australians，for example，were found to carry as few as one or two copies of the virus for every 100000 T cells. People with AIDS，by contrast，are burdened with viral loads thousands of times higher. (5) At the very least，the nef gene offers an attractive target for drug developers. If its activity can be blocked，suggests Deacon，researchers might be able to hold the progression of disease at bay，even in people who have developed full-blown AIDS. The need for better AIDS-fighting drugs was underscored last week by the actions of a U.S. Food and Drug Administration advisory panel，which recommended speedy approval of two new AIDS drugs，including the first of a new class of compounds called protease? inhibitors?. Although FDA commissioner David Kessler was quick to praise the new drugs，neither medication can prevent or cure AIDS once it has taken hold.

四川大学2012考博英语真题及答案详解 阅读 1）Sign has become a scientific hot button. Only in the past 20 years have specialists in language study realized that signed languages are unique—a speech of the hand. They offer a new way to probe how the brain generates and understands language, and throw new light on an old scientific controversy: whether language, complete with grammar, is something that we are born With, or whether it is a learned behavior. The current interest in sign language has roots in the pioneering work of one rebel teacher at Gallaudet University in Washington, D. C., the world’s only liberal arts university for deaf people. When Bill Stokoe went to Gallaudet to teach English, the school enrolled him in a course in signing. But Stokoe noticed something odd: among themselves, students signed differently from his classroom teacher. Stokoe had been taught a sort of gestural code, each movement of the hands representing a word in English. At the time, American Sign Language (ASL) was thought to be no more than a form of pidgin English (混杂英语). But Stokoe believed the “hand talk” his students used looked richer. He wondered: Might deaf people actually: have a genuine language? And could that language be unlike any other on Earth? I t was 1955, when even deaf people dismissed their signing a s “substandard”. Stokoe’s idea was academic heresy (异端邪说). It is 37 years later. Stokoe—now devoting his time to writing and editing books and journals and to producing video materials on ASL and the deaf culture—is having lunch at a cafe near the Gallaudet campus and explaining how he started a revolution. For decades educators fought his idea that signed languages are natural languages like English, French and Japanese. They assumed language must be based on speech, the modulation (调节) of sound. But sign language is based on the movement of hands, the modulation of space. “What I said,” Stokoe explains, “is that language is not mouth stuff—it’s brain stuff.” 21. The study of sign language is thought to be _____C___. A) a new way to look at the learning of language B) a challenge to tradi t ional, views on the nature of language C) an approach: to simplifying the grammatical structure of a language D) an attempt to clarify misunderstanding about the origin of language（C） 22. The, present growing interest in sign language was stimulated by ___C_____. A) a famous scholar in the study of the human brain B) a leading specialist in the study of liberal arts C) an English teacher in a university for the deaf D) some senior experts in American Sign Language（C） 23. According to Stokoe, sign language is _____B___. A) a Substandard language B) a genuine language C) an artificial language D) an international language（B）

General English Admission Test For Non-English Major Ph.D. program (Harbin Institute of Technology) Passage One Questions 1-7 are based on the following passage: According to a recent theory, Archean-age gold-quartz vein systems were formed over two billion years ago from magmatic fluids that originated from molten granitelike bodies deep beneath the surface of the Earth. This theory is contrary to the widely held view that the systems were deposited from metamorphic fluids, that is, from fluids that formed during the dehydration of wet sedimentary rocks. The recently developed theory has considerable practical importance. Most of the gold deposits discovered during the original gold rushes were exposed at the Earth’s surface and were found because the y had shed trails of alluvial gold that were easily traced by simple prospecting methods. Although these same methods still leas to an occasional discovery, most deposits not yet discovered have gone undetected because they are buried and have no surface expression. The challenge in exploration is therefore to unravel the subsurface geology of an area and pinpoint the position of buried minerals. Methods widely used today include analysis of aerial images that yield a broad geological overview, geophysical techniques that provide data on the magnetic, electrical, and mineralogical properties of the rocks being investigated, and sensitive chemical tests that are able to detect : the subtle chemical halos that often envelop mineralization. However, none of these high-technology methods are of any value if the sites to which they are applied have never mineralized, and to maximize the chances of discovery the explorer must therefore pay particular attention to selecting the ground formations most likely to be mineralized. Such ground selection relies to varying degrees on conceptual models, which take into account theoretical studies of relevant factors. These models are constructed primarily from empirical observations of known mineral deposits and from theories of ore-forming processes. The explorer uses the models to identify those geological features that are critical to the formation of the mineralization being modeled, and then tries to select areas for exploration that exhibit as many of the critical features as possible. 1. The author is primarily concerned with . A. advocating a return to an older methodology. B. explaining the importance of a recent theory. C. enumerating differences between two widely used methods D. describing events leading to a discovery 2. According to passage, the widely held view of Archean-age gold-quartz vein
