Fo
11、r each question four answers are given. Read the passages carefully and choose the best answer to each question.The history of responds to the work of the artist Sandro Botticelli (1444-1510) suggests that widespread appreciation by critics is a relatively recent phenomenon. Writing in 1550, Vasari
12、expressed an unease with Botticellis work, admitting that the artist fitted awkwardly into his evolutionary scheme of the history of art. Over the next two centuries, academic art historians defamed Botticelli in favor of his fellows Florentine, Michelangelo. Even when anti-academic art historians o
13、f the early nineteenth century rejected many of the standards of evaluation adopted by their predecessors, Botticellis work remained outside of accepted taste, pleasing neither amateur observers nor connoisseurs. (Many of his best paintings, however, remained hidden away in obscure churches and priv
14、ate homes.)The primary reason for Botticellis unpopularity is not difficult to understand: most observers, up until the mid-nineteenth century, did not consider him to be noteworthy, because his work, for the most part, did not seem to these observers to exhibit the traditional characteristics of fi
15、fteenth-century Florentine art. For example, Botticelli rarely employed the technique of strict perspective and, unlike Michelangelo, never used chiaroscuro.Another reason for Botticellis unpopularity may have been that his attitude toward the style of classical art was very different from that of h
16、is contemporaries. Although he was thoroughly exposed to classical art, he showed little interest in borrowing from the classical style. Indeed, it is paradoxical that a painter of large-scale classical subjects adopted a style that was only slightly similar to that of classical art.In any case, whe
17、n viewers began to examine more closely the relationship of Botticellis work to the tradition of fifteenth-century Florentine art, his reputation began to grow. Analyses and assessments of Botticelli made between 1850 and 1870 by the artists of the Pre-Raphaelite movement, as well as by the writer P
18、ater (although he, unfortunately, based his assessment on an incorrect analysis of Botticellis personality), inspired a new appreciation of Botticelli throughout the English-speaking world. Yet Botticellis work, especially the Sistine frescoes, did not generate worldwide attention until it was final
19、ly subjected to a comprehensive and scrupulous analysis by Home in 1908. Home rightly demonstrated that the frescoes shared important features with paintings by other fifteenth-century Florentines-features such as skillful representation of anatomical proportions, and of the human figure in motion.
20、However, Home argued that Botticelli did not treat these qualities as ends in themselves-rather, that he emphasized clear depletion of a story, a unique achievement and one that made the traditional Florentine qualities less central. Because of Homes emphasis crucial to any study of art, the twentie
21、th century has come to appreciate Botticellis achievements.（分数：4.00）(1).Which of the following would be the best title for the text?（分数：1.00）填空项 1:_(2).We can learn from the text that art critics have a history of _（分数：1.00）填空项 1:_(3).The views of Vasari and Home on Botticellis products are _ A. ide
22、ntical.（分数：1.00）填空项 1:_(4).The word “connoisseurs“ (Paragraph 1) most probably means _（分数：1.00）填空项 1:_In the next century well be able to alter our DNA radically, encoding our visions and vanities while concocting new life-forms. When Dr. Frankenstein made his monster, he wrestled with the moral iss
23、ue of whether he should allow it to reproduce, “Had I the right, for my oval benefit, to inflict the curse upon everlasting generations?“ Will such questions require us to develop new moral philosophies?Probably not. Instead, well reach again for a time-tested moral concept, one sometimes called the
24、 Golden Rule and which Kant, the millenniums most prudent moralist, conjured up into a categorical imperative: Do unto others as you would have them do unto you; treat each person as an individual rather than as a means to some end.Under this moral precept we should recoil at human cloning, because
25、it inevitably entails using humans as means to other humans ends and valuing them as copies of others we loved or as collections of body parts, not as individuals in their own right. We should also draw a line, however fuzzy, that would permit using genetic engineering to cure diseases and disabilit
26、ies but not to change the personal attributes that make someone an individual (IQ, physical appearance, gender and sexuality).The biotech age will also give us more reason to guard our personal privacy. Aldous Huxley in Brave New World, got it wrong: rather than centralizing power in the hands of th
27、e state, DNA technology has empowered individuals and families. But the state will have an important role, making sure that no one, including insurance companies, can look at our genetic data without our permission or use it to discriminate against us.Then we can get ready for the breakthroughs that
28、 could come at the end of the next century and the tech nology is comparable to mapping our genes: plotting the 10 billion or more neurons of our brain. With that information we might someday be able to create artificial intelligences that think and experience consciousness in ways that are indistin
29、guishable from a human brain. Eventually we might be able to replicate our own minds in a “dry-ware“ machine, so that we could live on without the “wet-ware“ of a biological brain and body. The 20th centurys revolution in infotechnology will thereby merge with the 21st centurys revolution in biotech
30、nology. But this is science fiction. Lets turn the page now and get back to real science.（分数：3.00）(1).Dr. Frankensteins remarks are mentioned in the text _（分数：1.00）填空项 1:_(2).It can be concluded from the text that the technology of human cloning should be employed _ A. excessively and extravagantly.
31、（分数：1.00）填空项 1:_(3).From the text, we learn that Aldous Huxley is of the opinion that _（分数：1.00）填空项 1:_Before a big exam, a sound nights sleep will do you more good than poring over textbooks. That, at least, is the folk wisdom. And science, in the form of behavioral psychology, supports that wisdom
32、. But such behavioral studies cannot distinguish between two competing theories of why sleep is good for the memory. one says that sleep is when permanent memories form. The other says that they are actually formed during the day, but then “edited“ at night, to flush away what is superfluous.To tell
33、 the difference, it is necessary to look into the brain of a sleeping person, and that is hard. But after a decade of painstaking work, a team led by Pierre Maquet at Liege University in Belgium has managed to do it. The particular stage of sleep in which the Belgian group is interested in is rapid
34、eye movement (REM) sleep, when brain and body are active, heart rate and blood pressure increase, the eyes move back and forth behind the eyelids as if watching a movie, and brainwave traces resemble those of wakefulness. It is during this period of deep that people are most likely to relive events
35、of the previous day in dreams.Dr. Maquet used an electronic device called PET to study the brains of people as they practiced a task during the day, and as they slept during the following night. The task required them to press a button as fast as possible, in response to a light coming on in one of
36、six positions. As they learnt how to do this, their response times got faster. What they did not know was that the appearance of the lights sometimes followed a pattern-what is referred to as “artificial grammar“. Yet the reductions in response time showed that they learnt faster when the pattern wa
37、s present than when there was not.What is more, those with more to learn (i. e. , the “grammar“, as well as the mechanical task of pushing the button) have more active brains. The “editing“ theory would not predict that, since the number of irrelevant stimuli would be the same in each case. And to e
38、liminate any doubts that the experimental subjects were learning as opposed to unlearning, their response times when they woke up were even quicker than when they went to sleep.The team, therefore, concluded that the nerve connections involved in memory are reinforced through reactivation during REM
39、 sleep, particularly if the brain detects an inherent structure in the material being learnt. So now, on the eve of that crucial test, maths students can sleep soundly in the knowledge that what they will remember the next day are the basic rules of algebra and not the incoherent talk from the radio
40、 next door.（分数：3.00）(1).Researchers in behavioral psychology are divided with regard to _（分数：1.00）填空项 1:_(2).As manifested in the experimental study, rapid eye movement is characterized by _（分数：1.00）填空项 1:_(3).By referring to the artificial grammar, the author intends to show _ A. its significance i
41、n the study.（分数：1.00）填空项 1:_B./B Read the following passage carefully and then explain in your own English the exact meaning of the numbered and underlined parts.Medical consumerism-like all sorts of consumerism, only more menacingly-is designed to be satisfying. (51)U The prolongation of life and t
42、he search for perfect health(beauty, youth, happiness) are inherently self-defeating./U The law of diminishing returns necessarily applies. You can make higher percentages of people survive into their eighties and nineties. But, as any geriatric ward shows, that is not the same as to confer enduring
43、 mobility, awareness and autonomy. (52)UExtending life grows medically feasible, but it is often a life deprived of everything, and one exposed to degrading neglect as resources grow over-stretched and politics turn mean./UWhat an ignominious destiny for medicine if its future turned into one of bes
44、towing meager increments of unenjoyed life! It would mirror the fate of athletics, in which disproportionate energies and resources not least medical ones, like illegal steroids-are now invested to shave records by milliseconds. And, it goes without saying; the logical extension of longevism-the “ab
45、olition“ of death-would not be a solution but only an exacerbation. (53)UTo air these predicaments is not antimedical spleen/U-a churlish reprisal against medicine for its victories-but simply to face the growing reality of medical power not exactly without responsibility but with dissolving goals.(
46、54) UHence medicines finest hour becomes the dawn of its dilemmas./U For centuries, medicine as impotent and hence unproblematic. From the Greeks to the Great War, its job was simple: to struggle with lethal diseases and gross disabilities, to ensure live births, and to manage pain. It performed the
47、se uncontroversial tasks by and large with meager success. Today, with mission accomplished, medicines triumphs are dissolving in disorientation. (55) UMedicine has led to vastly inflated expectations, which the public has eagerly swallowed./U Yet as these expectations grow unlimited, they become un
48、fulfillable. The task facing medicine in the twenty-first century will be to redefine its limits even as it extends its capacities.（分数：5.00）(1).（分数：1.00）填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_三、BPart Four Cloze(总题数：1，分数：10.00)Fill in each numbered blank in the following passage with ONE suitable word to complete the passage.For most kinds of activities, a large group of people can accomplish mo
