20、n Reading Co(总题数：0，分数：0.00)七、Part A(总题数：0，分数：0.00)八、Passage 1(总题数：1，分数：5.00)When an invention is made, the inventor has three possible courses of action open to him. he can give the invention to the world by publishing it, keep the idea secret, or patent it.A granted patent is the result of a bargai

21、n struck between an inventor and the state, by which the inventor gets a limited period of monopoly and publishes full details of his invention to the public after that period terminates.Only in the most exceptional circumstances is the lifespan of a patent extended to alter this normal process of e

22、vents.The longest extension ever granted was to Georges Valensi; his 1939 patent for color TV receiver circuitry was extended until 1971 because for most of the patents normal life there was no colour TV to receive and thus no hope of reward for the invention.Because a patent remains permanently pub

23、lic after it has terminated, the shelves of the library attached to the patent office contain details of literally millions of ideas that are free for anyone to use and, if older than half a century, sometimes even repatent. Indeed, patent experts often advise anyone wishing to avoid the high cost o

24、f conducting a search through live patents that the one sure way of avoiding violation of any other inventors right is to plagiarize a dead patent. Likewise, because publication of an idea in any other form permanently invalidates further patents on that idea, it is traditionally safe to take ideas

25、from other areas of print. Much modern technological advance is based on these presumptions of legal security.Anyone closely involved in patents and inventions soon learns that most “new“ ideas are, in fact, as old as the hills. It is their reduction to commercial practice, either through necessity

26、or dedication, or through the availability of new technology, that makes news and money. The basic patent for the theory of magnetic recording dates back to 1886. Many of the original ideas behind television originate from the late 19th and early 20th century. Even the Volkswagen rear engine car was

27、 anticipated by a 1904 patent for a cart with the horse at the rear.（分数：5.00）(1).The passage is mainly about _.A. an approach to patentsB. the application for patentsC. the use of patents D. the access to patents（分数：1.00）A.B.C.D.(2).Which of the following is TRUE according to the passage?A. When a p

28、atent becomes out of effect, it can be repatented or extended if necessary.B. It is necessary for an inventor to apply for a patent before he makes his invention public.C. A patent holder must publicize the details of his invention when its legal period is over.D. One can get all the details of a pa

29、tented invention from a library attached to the patent office.（分数：1.00）A.B.C.D.(3).George Valensis patent lasted until 1971 because _.A. nobody would offer any reward for his patent prior to that timeB. his patent could not be put to use for an unusually long timeC. there were not enough TV stations

30、 to provide colour programmesD. the colour TV receiver was not available until that time（分数：1.00）A.B.C.D.(4).The word “plagiarize“ in the fifth paragraph most probably means “ _ . “A. steal and useB. give reward toC. make publicD. take and change（分数：1.00）A.B.C.D.(5).From the passage we learn that _.

31、A. an invention will not benefit the inventor unless it is reduced to commercial practiceB. products are actually inventions which were made a long time agoC. it is much cheaper to buy an old patent than a new oneD. patent experts often recommend patents to others by conducting a search through dead

32、 patents（分数：1.00）A.B.C.D.九、Passage 2(总题数：1，分数：5.00)Americans today dont place a very high value on intellect. Our heroes are athletes, entertainers, and entrepreneurs, not scholars. Even our schools are where we send our children to get a practical education-not to pursue knowledge for the sake of k

33、nowledge. Symptoms of pervasive anti-intellectualism in our schools arent difficult to find.“Schools have always been in a society where practical is more important than intellectual,“ says education writer Diane Ravitch. “Schools could be a counterbalance. “Ravitchs latest book, Left Back: A Centur

34、y of Failed School Reforms, traces the roots of anti-intellectualism in our schools, concluding they are anything but a counterbalance to the American distaste for intellectual pursuits.But they could and should be. Encouraging kids to reject the life of the mind leaves them vulnerable to exploitati

35、on and control. Without the ability to think critically, to defend their ideas and understand the ideas of others, they cannot fully participate in our democracy. Continuing along this path, says writer Earl Shorris, “We will become a second rate country. We will have a less civil society.“Intellect

36、 is resented as a form of power or privilege,“ writes historian and professor Richard Hofstadter in Anti-Intellectualism in American Life, a Pulizer Prize winning book on the roots of anti-intellectualism in US politics, religion, and education. From the beginning of our history, says Hofstadter, ou

37、r democratic and populist urges have driven us to reject anything that smells of elitism. Practicality, common sense, and native intelligence have been considered more noble qualities than anything you could learn from a book.Ralph Waldo Emerson and other Transcendentalist philosophers thought schoo

38、ling and rigorous book learning put unnatural restraints on children: “We are shut up in schools and college recitation rooms for 10 or 15 years and come out at last with a bellyful of words and do not know a thing. “Mark Twains Huckleberry Finn exemplified American anti-intellectualism. Its hero av

39、oids being civilized - going to school and learning to read - so he can preserve his innate goodness.Intellect, according to Hofstadter, is different from native intelligence, a quality we reluctantly admire. Intellect is the critical, creative, and contemplative side of the mind. Intelligence seeks

40、 to grasp, manipulate, reorder, and adjust, while intellect examines, ponders, wonders, theorizes, criticizes, and imagines.School remains a place where intellect is mistrusted. Hofstadter says our countrys educational system is in the grips of people who “joyfully and militantly proclaim their host

41、ility to intellect and their eagerness to identify with children who show the least intellectual promise./（分数：5.00）(1).What do American parents expect their children to acquire in school?A. The habit of thinking independently.B. Profound knowledge of the world.C. Practical abilities for future caree

42、r.D. The confidence in intellectual pursuits.（分数：1.00）A.B.C.D.(2).We can learn from the text that Americans have a history of_.A. undervaluing intellect B. favoring intellectualismC. supporting school reform D. suppressing native intelligence（分数：1.00）A.B.C.D.(3).The views of Ravitch and Emerson on s

43、chooling are_.A. identical B. similarC. complementary D. opposite（分数：1.00）A.B.C.D.(4).Emerson, according to the text, is probably_.A. a pioneer of education reform B. an opponent of intellectualismC. a scholar in favor of intellect D. an advocate of regular schooling（分数：1.00）A.B.C.D.(5).What does th

44、e author think of intellect?A. It is second to intelligence. B. It evolves from common sense.C. It is to be pursued. D. It underlies power.（分数：1.00）A.B.C.D.十、Passage 3(总题数：1，分数：5.00)When it comes to the slowing economy, Ellen Spero isnt biting her nails just yet. But the 47- year-old manicurist isnt

45、 cutting, filing or polishing as many nails as shed like to, either. Most of her clients spend $12 to $50 weekly, but last month two longtime customers suddenly stopped showing up. Spero blames the softening economy. “Im a good economic indicator,“ she says. “I provide a service that people can do w

46、ithout when theyre concerned about saving some dollars.“ So Spero is downscaling, shopping at middle-brow Dillards department store near her suburban Cleveland home, instead of Neiman Marcus. “I dont know if other clients are going to abandon me, too,“ she says.Even before Alan Greenspans admission

47、that Americas red-hot economy is cooling, lots of working folks had already seen signs of the slowdown themselves. From car dealerships to Gap outlets, sales have been lagging for months as shoppers temper their spending. For retailers, who last year took in 24% of their revenue between Thanksgiving

48、 and Christmas, the cautious approach is coming at a crucial time. Already, experts say, holiday sales are off 7% from last years pace. But dont sound any alarms just yet. Consumers seem only mildly concerned, not panicked, and many say they remain optimistic about the economys long-term prospects,

49、even as they do some modest belt-tightening.Consumers say theyre not in despair because, despite the dreadful headlines, their own fortunes still feel pretty good. Home prices are holding steady in most regions. In Manhattan, “theres a new gold rush happening in the $4 million to $10 million range, predominantly
