医学考博英语翻译习题

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.

2012四川大学考博英语真题及答案详解

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)

哈工大考博英语真题及答案

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

2015中国科技大学考博英语真题阅读理解精练

2015中国科技大学考博英语真题阅读理解精练Is it possible to persuade mankind to live without war?War is an ancient institution,which has existed for at least six thousand years. It was always bad and usually foolish,but in the past human race managed to live with it.Modern ingenuity has changed this.Either man will abolish war,or war will abolish man.For the present,it is nuclear weapons that cause the most serious danger,but bacteriological or chemical weapons may,before long,offer an even greater threat.If we succeed in abolishing nuclear weapons,our work will not be done.It will never be done until we have succeeded in abolishing war.To do this,we need to persuade mankind to look upon international questions in a new way,not as contests of force,in which the victory goes to the side which is most skillful in killing people,but by arbitration in accordance with agreed principles of law.It is not easy to change very old mental habits,but this is what must be attempted. There are those who say that the adoption of this or that ideology would prevent war.I believe this to be a big error.All ideologies are based upon dogmatic statements that are,at best,doubtful,and at worst,totally false.Their adherents believe in them so fanatically that they are willing to go to war in support of them. The movement of world opinion during the past few years has been very largely such as we can welcome.It has become a commonplace that nuclear war must be avoided.Of course very difficult problems remain
