哈工大博士英语考试冲刺试题三 Passage 1 The realm of product liability is one that has always put legal scholars and practitioners at odds. Viewed by some as genuine efforts to protect the public from dangerous goods and others as an excuse for dirty lawyers to sue rich companies, the matter has yet to be resolved. Product liability, and its implications for disgruntled consumers wishing to sue the makers of what they buy, continues to be debated. Those who argue that current product liability laws are positive assert that without such laws, manufacturers would be free to do as they please without regard for the safety of the consumers who buy their products. As a result, they argue, shoddy merchandise would emerge, with every possible corner cut in order to lower costs, at the expense of quality. Not only would the shoddy merchandise be a rip-off, however, but the products could likely be harmful as well. Proponents of this point of view hail the new wave of warning labels and increased quality assurance that has resulted from recent product liability legislation, confident in their conviction that it has made the American marketplace a safer place to shop. Opponents of the current status-quo, however, cite the overwhelming amount of litigation that has taken place as a result of stricter product liability. A moderate approach id advised by this group, between the necessary safeguards that would prevent abuse of the system by the companies and the excessive consumer-protection laws that allow producers to be sued at the drop of a hat. These people argue that greed and the alluring possibility of easy money lead unscrupulous buyers to look for any excuse to bring minor grievances to court, hoping for a million-dollar outcome. As the situation stands now, the former camp is getting its way, reflecting society's priority of safety over economics. Recent lobbying by producers have begun to shift the tide, however, as abuse of product liability laws continues and grows, courts are beginning to note the trend and take appropriate measures, casting a keener eye on such cases so as to distinguish between frivolous cases and more serious claims. In regard to the future of product liability legislation and its relation to our ever increasingly litigious society, only time will tell. 1.It is stated that consumers who bring product liability problems to litigation ____ A.Are primarily motivated by the possibility of quick money through a lawsuit B.Suffer injures from faulty merchandise and deserve appropriate compensation C.Will find their options limited in the future as product liability laws will move toward a more moderate position D.Bring their issues to litigation based on both legitimate and profit-seeking groups 2.Manufacturers in the text tend to ____ A.Invariable produce dangerous products that require legislation to ensure safety B.Hold profit and cost-cutting in higher regard than consumer safety C.Be the victims of a legal institution that unfairly targets them D.Be bound by the current system, causing them to take caution in producing their products 3.Those who favor less strict product liability laws believe that ____ A.Such laws curb producers' ability to create shoddy merchandise to attain greater profit B.The laws need to be modified to better serve the needs both consumers and producers

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

哈工大博士英语考试冲刺试题二 Passage 1 We have come a long way since 1896, and the clock cannot be turned back. Indeed, not only are women increasingly taking their rightful place on the Olympics athletics track, but there are also growing signs that the myth of their inevitable sporting inferiority may be about to be shattered for good. Women certainly are catching up fast. But although all the evidence points to a relentless closing of the gap between the athletics performances of men and women, there is still one last obstacle the women have to overcome: blind male prejudice. “Women can out-perform men in endurance events, and at extremes of heat and cold,” says Dr Graig Sharp, of Birmingham University’s Department of Physical Education. “But in speed events, for a number of physiological reasons, the gender gap will level out at about 10 percent.” Other experts, however, see no reason why women won’t continue to narrow the gap even beyond that margin. “We cannot rely on physiology to assert that sex differences are fixed and inevitable. Women have always had fewer chances to train or participate to the same extent in most sports,” says Dr Kenneth Dyer of Adelaide University. In Britain sportswomen still face discrimination, even after the 1975 Sex Discrimination Act outlawed most forms of discrimination on
