It has been known for over 200 years, ever since a zoologist-illustrator named George Edwards decided to watch the behavior of pet marmosets in a London garden, that among certain species of New World monkeys males contributed direct care for infants that equaled or exceeded that given by females. Mothers among marmosets and tamarins typically give birth to twins, as often as twice a year, and to ease the female in her staggering reproductive burden the male carries the infant at all times except when the mother is actually suckling it. It was assumed by Kleiman that monogamy and male confidence of paternity were essential to the evolution of such care, and at the same time, it was assumed by Symons and others that monogamy among primates must be fairly rare.Recent findings, however, make it necessary to reverse this picture. First of all, monogamy among primates turns out to be rather more frequent than previously believed (either obligate or facultive monogamy can be documented for some 17-20 percent of extant primates) and second, male care turns out to be far more extensive than previously thought and notnecessarily confined to monogamous species, according to Hrdy. Whereas previously, it was assumed that monogamy and male certainty of paternity facilitated the evolution of male care, it now seems appropriate to consider the alternative possibility, whether the extraordinary capacity of male primates to look out for the fates of infants did not in some way pre-adapt members of this order for the sort of close, long-term relationships between males and females that, under some ecological circumstances, leads to monogamy! Either scenario could be true. The point is that on the basis of present knowledge there is no reason to view male care as a restricted or specialized phenomenon. In sum, though it remains true that mothers among virtually all primates devote more time and/or energy to rearing infants than do males, males nonetheless play a more varied and critical role in infant survival than is generally realized.1. The author of the passage mentions the work of Hrdy primarily toA. present an instance of an untenable assumptionB. illustrate a consensus by citing a representative claimC. provide evidence that challenges a beliefD. highlight a corollary of a widespread viewE. offer data that help resolve a debate2. According to the passage, the evolutionary relationship between male care and monogamy isA. incontestableB. immutableC. uncommonD. immaterialE. uncertain3. The author of the passage suggests that it is “appropriateto consider the alternative possibility” because the previous viewA. results in a contradictionB. depends on problematic dataC. appears less definite given certain factsD. conflates two distinct phenomenaE. overlooks a causal relationship between correlated phenomena4. Which of the following statements, if true, would pose the grea test challenge to “the alternative possibility”?A. The number of primate species in which male care of infants is exhibited is greater than the number of primate species that practice monogamy.B. Male care of infants among primates can be seen earlier in the evolutionary record than can monogamy among primates.C. Monogamous relationships among primates can be found in species living in a variety of physical environments.D. Most primate species that practice monogamy do not show any evidence of male care of infants.E. Male care of infants can be observed in some primate species that lack male confidence of paternity.答案：CECAGRE阅读容易被你所忽视的三类词汇perspective 透视画法;观点，方法;前景，远景prospect 前景，景色;前途;勘探，寻找appreciate 理解，认识，意识到;欣赏;感激elaborate v.&adj. 精心制作，详细描述;精心制作的address v.从事，忙于;n. 演讲appropriate v. 拨给(资金)，盗用/ adj.合适的strain n. 血统，品系，菌株;紧张，张力;v.扭伤，拉紧article n. 物品，商品intrigue v.&n 激发兴趣;密谋;阴谋intriguing adj. 激发兴趣的assume v. 承担，担任;假装;假设bark n. 树皮;犬吠bill n.议案，法案;鸟嘴;账单champion vt. 支持，拥护;n.冠军aging n.老化，陈酿complex n. 综合体 adj.复杂的concern n. 公司(垄断组织“康采恩”就是它的音译)attribute v.&n 归因于;特征，属性default n.&v. 不履行;违约;拖欠;默认(值)drill vt. 钻(孔);训练，操练exploit v. 开发，利用n. 功绩fair n. 集市，交易会;adj.公平的，美丽的 adv.公平地，直接地fairly adv. 相当地，公平地game n. 猎物，野味fashion vt. 形成，塑造 n.时尚，方式inviting adj. 引人注目的，吸引人的alternate v.&adj. 交替，轮流; 交替的alternating adj.交互的，交替的alternative n.&adj. 可供选择的方案(option);选择性的(optional) GRE阅读如何把握作者写作态度有利于解题1.社会现象.作者反对将社会现象拔高到阶级、政治、意识形态或超人性的高度，反对各种左派思想、革命主张和马克思主义。

In a 1984 book, Claire C.Robertson argued that,before colonialism, age was Line a more important indicator (5) of status and authority thangender in Ghana and inAfrica generally. Britishcolonialism imposedEuropean-style male-(10) dominant notions uponmore egalitarian localsituations to the detrimentof women generally, andgender became a defining (15) characteristic that weak-ened women’s power andauthority.Subsequent research inKenya convinced Robertson (20) that she had overgeneralized about Africa. Before colo-nialism, gender was moresalient in central Kenya thanit was in Ghana, although age (25) was still crucial in determin-ing authority. In contrast withGhana, where women hadtraded for hundreds of yearsand achieved legal majority (30) (not unrelated phenomena),the evidence regardingcentral Kenya indicated thatwomen were legal minorsand were sometimes treated (35) as male property, as wereEuropean women at thattime. Factors like strongpatrilinearity and patrilocality, as well as women’s inferior (40) land rights and lesserinvolvement in trade, madewomen more dependent onmen than was generally thecase in Ghana. However,(45) since age apparentlyremained the overridingprinciple of social organiza-tion in central Kenya, somesenior women had much(50) authority. Thus, Robertsonrevised her hypothesissomewhat, arguing thatin determining authority inprecolonial Africa age was a(55) primary principle that super-seded gender to varyingdegrees depending on thesituation.--------------------------------------------------------------------------------Q3:The primary purpose of the passage is to1.present evidence undermining a certain hypothesis2.describe a particular position and its subsequent modification3.discuss two contrasting viewpoints regarding a particular issue4.describe how a social phenomenon varied by region5.evaluate an assumption widely held by scholarsActing on the recommen-dation of a British governmentcommittee investigating theLine high incidence in white lead(5) factories of illness amongemployees, most of whomwere women, the Home Sec-retary proposed in 1895 thatParliament enact legislation(10) that would prohibit women fromholding most jobs in white leadfactories. Although theWomen’s Industrial DefenceCommittee (WIDC), formed(15) in 1892 in response to earlierlegislative attempts to restrictwomen’s labor, did not dis-count the white lead trade’spotential health dangers, it(20) opposed the proposal, view-ing it as yet another instanceof limiting women’s workopportunities. Also opposingthe proposal was the Society(25) for Promoting the Employmentof Women (SPEW), whichattempted to challenge it byinvestigating the causes of ill-ness in white lead factories.(30)SPEW contended, and WIDCconcurred, that controllableconditions in such factorieswere responsible for the devel-opment of lead poisoning.(35) SPEW provided convincingevidence that lead poisoningcould be avoided if workerswere careful and clean andif already extant workplace(40) safety regulations werestringently enforced. How-ever, the Women’s TradeUnion League (WTUL), whichhad ceased in the late 1880’s(45) to oppose restrictions onwomen’s labor, supported theeventually enacted proposal,in part because safety regu-lations were generally not(50) being enforced in white leadfactories, where there were nounions (and little prospect ofany) to pressure employers tocomply with safety regulations.--------------------------------------------------------------------------------Q20:The passage is primarily concerned with1.presenting various groups’ views of the motives of those proposing certain legislation2.contrasting the reasoning of various groups concerning their positions on certainproposed legislation3.tracing the process whereby certain proposed legislation was eventually enacted4.assessing the success of tactics adopted by various groups with respect to certainproposed legislation5.evaluating the arguments of various groups concerning certain proposedlegislationManufacturing site location is an important consideration in determining the optimal deployment of a firm’sproduction resources, but one that is usually given only limit ed attention.Most pre-1990 literature on businesses’ use of information technology (IT)—defined as any form of computer-based information system—focused on spectacular ITsuccesses and reflected a general optimism concerning IT’s potential as a resource for creating competitive advantage. But toward the end of the 1980’s, some economists spoke of a “productivity paradox”: despite huge IT investments, most notably in the service sectors, productivity stagnated.The idea that equipping homes with electrical appliancesand other “modern”household technologies would eliminate drudgery, save labor time, and increase leisure for women who were full-time home workersremained largely unchallenged until the women’s movement of the 1970’s spawned the groundbreaking andinfluential works of sociologist Joann Vanek and historian Ruth Cowan.In recent years, Western business managers have been heeding the exhortations of business journalists and academics to move their companies toward long-term,collaborative “st rategic partnerships” with their external business partners (e.g.,suppliers).Until recently, zoologists believed thatall species of phocids (true seals), a pin-niped family, use a different maternalLine strategy than do otariids (fur seals and(5) sea lions), another pinniped family. Motherotariids use a foraging strategy. Theyacquire moderate energy stores in theform of blubber before arriving at breedingsites and then fast for 5 to 11 days after(10) birth. Throughout the rest of the lactation(milk production) period, which lasts from4 months to 3 years depending on thespecies, mother otariids alternately for-age at sea, where they replenish their fat(15) stores, and nurse their young at breed-ing sites. Zoologists had assumed thatfemales of all phocid species, by contrast,use a fasting strategy in which motherphocids, having accumulated large energy(20) stores before they arrive at breeding sites,fast throughout the entire lactation period,which lasts from 4 to 50 days depending onthe species. However, recent studies onharbor seals, a phocid species, found that(25) lactating females commenced foragingapproximately 6 days after giving birth andon average made 7 foraging trips duringthe remain der of their 24-day lactationperiod.(30) The maternal strategy evolved byharbor seals may have to do with theirsmall size and the large proportion of theirfat stores depleted in lactation. Harborseals are small compared with other phocid(35) species such as grey seals, northern ele-phant seals, and hooded seals, all of whichare known to fast for the entire lactationperiod. Studies show that mother seals ofthese species use respectively 84 percent,(40) 58 percent, and 33 percent of their fatstores during lactation. By comparison,harbor seals use 80 percent of their fatstores in just the first 19 days of lactation,even though they occasionally feed during(45) this period. Since such a large proportionof their fat stores is exhausted despitefeeding, mother harbor seals clearly cannotsupport all of lactation using only energystored before giving birth. Though smaller(50)than many other phocids, harbor seals aresimilar in size to most otariids. In addition,there is already some evidence suggestingthat the ringed seal, a phocid species thatis similar in size to the harbor seal, mayalso use a maternal foraging strategy.Q34:The primary purpose of the passage is to1.present evidence that several phocid species use the maternal fasting strategy2.explain why the maternal strategy typically used by phocids is different from thematernal strategy used by otariids3.argue that zoologists’ current understanding of harbor seals’ maternal strategy isincorrect4.describe an unexpected behavior observed in harbor seals and propose anexplanation that may account for that behavior5.describe evidence concerning the maternal strategy of the harbor seal and suggest thatthe harbor seal belongs to the otariid rather than to the phocid familyRecent feminist scholarship con-cerning the United States in the 1920’schallenges earlier interpretations thatLine assessed the twenties in terms of the(5)unkept “promises” of the women’ssuffrage movement. This new scholar-ship disputes the long-held view thatbecause a women’s voting bloc did notmaterialize after women gained the right(10) to vote in 1920, suffrage failed toproduce long-term political gains forwomen. These feminist scholars alsochallenge the old view that pronouncedsuffrage a failure for not delivering on(15)the promise that the women’s votewould bring about moral, corruption-free governance. Asked whetherwomen’s suffrage was a failure, thesescholars cite the words of turn-of-the-(20) century social reformer Jane Addams,“Why don’t you ask if suffrage ingeneral is failing?”In some ways, however, thesescholars still present the 1920’s as a(25) period of decline. After suffrage, theyargue, the feminist movement lost itscohesiveness, and gender conscious-ness waned. After the mid-1920’s, fewsuccesses could be claimed by fem-(30) inist reformers: little could be seen inthe way of legislative victories.During this decade, however, therewas intense activism aimed at achiev-ing increased autonomy for women,(35) broadening the spheres within whichthey lived their daily lives. Women’sorganizations worked to establishopportunities for women: they strove tosecure for women the full entitlements(40) of citizenship, including the right to holdoffice and the right to serve on juries.--------------------------------------------------------------------------------Q2:The passage is primarily concerned with1.providing evidence indicating that feminist reformers of the 1920’s failed to reachsome of their goals2.presenting sc holarship that contrasts suffragist “promises” with the historical realitiesof the 1920’s3.discussing recent scholarship concerning the achievements of women’s suffrageduring the 1920’s and presenting an alternative view of those achievements4.outlining recent findings concerning events leading to suffrage for women in the1920’s and presenting a challenge to those findingsE． providing support for a traditional view of the success of feminist attempts toincrease gender consciousness among women during the 1920Some historians contend that con-ditions in the United States during theSecond World War gave rise to aLine dynamic wartime alliance between(5) trade unions and the African Americancommunity, an alliance that advancedthe cause of civil rights. They con-clude that the postwar demise of thisvital alliance constituted a lost oppor-(10) tunity for the civil rights movement thatfollowed the war. Other scholars,however, have portrayed organizedlabor as defending all along the rela-tively privileged position of White(15) workers relative to African Americanworkers. Clearly, these two perspec-tives are not easily reconcilable, butthe historical reality is not reducibleto one or the other.(20)Unions faced a choice betweeneither maintaining the prewar statusquo or promoting a more inclusiveapproach that sought for all membersthe right to participate in the internal(25) affairs of unions, access to skilledand high-paying positions within theoccupational hierarchy, and protec-tion against management’s arbitraryauthority in the workplace. While(30) union representatives often voicedthis inclusive ideal, in practice unionsfar more often favored entrenchedinterests. The accelerating develop-ment of the civil rights movement(35) following the Second World Warexacerbated the unions’ dilemma,forcing trade unionists to confrontcontradictions in their own practices.--------------------------------------------------------------------------------Q6:The passage is primarily concerned with1.providing a context within which to evaluate opposing viewpoints about ahistorical phenomenon2.identifying a flawed assumption underlying one interpretation of a historicalphenomenon3.assessing the merits and weaknesses of a controversial theory about a historicalphenomenon4.discussing the historical importance of the development of a wartime alliance5.evaluating evidence used to support a particular interpretation of a historicalphenomenonA small number of the forestspecies of lepidoptera (moths andbutterflies, which exist as caterpillarsLine during most of their life cycle) exhibit(5) regularly recurring patterns of popu-lation growth and decline—suchfluctuations in population are knownas population cycles. Although manydifferent variables influence popula-(10) tion levels, a regular pattern such asa population cycle seems to imply adominant, driving force. Identificationof that driving force, however, hasproved surprisingly elusive despite(15) considerable research. The com-mon approach of studying causes ofpopulation cycles by measuring themortality caused by different agents,such as predatory birds or parasites,(20) has been unproductive in the case oflepidoptera. Moreover, populationecologists’ attempts to alter cyclesby changing the caterpillars’ habitatand by reducing caterpillar popula-(25) tions have not succeeded. In short,the evidence implies that these insectpopulations, if not self-regulating, mayat least be regulated by an agent moreintimately connected with the insect than (30) are predatory birds or parasites.Recent work suggests that thisagent may be a virus. For manyyears, viral disease had beenreported in declining populations (35) of caterpillars, but population ecolo-gists had usually considered viraldisease to have contributed to thedecline once it was underway ratherthan to have initiated it. The recent (40) work has been made possible bynew techniques of molecular biologythat allow viral DNA to be detectedat low concentrations in the environ-ment. Nuclear polyhedrosis viruses (45) are hypothesized to be the drivingforce behind population cycles inlepidoptera in part because theviruses themselves follow an infec-tious cycle in which, if protected from (50) direct sun light, they may remainvirulent for many years in the envi-ronment, embedded in durablecrystals of polyhedrin protein.Once ingested by a caterpillar,(55) the crystals dissolve, releasingthe virus to infect the insect’s cells.Late in the course of the infection,millions of new virus particles areformed and enclosed in polyhedrin (60) crystals. These crystals reenter theenvironment after the insect dies anddecomposes, thus becoming avail-able to infect other caterpillars.One of the attractions of this(65) hypothesis is its broad applicability.Remarkably, despite significant differ-ences in habitat and behavior, manyspecies of lepidoptera have populationcycles of similar length, between eight(70) and eleven years. Nuclear polyhe-drosis viral infection is one factor thesedisparate species share.Q36:The primary purpose of the passage is toA. describe the development of new techniques that may help to determine thedriving force behind population cycles in lepidopteraB. present evidence that refutes a particular theory about the driving forcebehind population cycles in lepidopteraC.present a hypothesis about the driving force behind population cycles inlepidopteraD.describe the fluctuating patterns of population cycles in lepidopteraE.question the idea that a single driving force is behind population cycles inlepidopteraScattered around the globe are more than 100 small regions of isolated volcanic activity known to geologists as hot spots. Unlike most of the world's volcanoes, they are not always found at the boundaries of the great drifting plates that make up the earth's surface; on the contrary, many of them lie deep in the interior of a plate. Most of the hot spots move only slowly, and in some cases the movement of the plates past them has left trails of dead volcanoes. The hot spots and their volcanic trails are milestones that mark the passage of the plates.That the plates are moving is not beyond dispute. Africa and South America, for example, are moving away from each other as new material is injected into the sea floor between them. The complementary coastlines and certain geological features that seem to span the ocean are reminders of where the two continents were once joined. The relative motion of the plates carrying these continents has been constructed in detail, but the motion of one plate with respect to another cannot readily be translated into motion with respect to the earth's interior. It is not possible to determine whether both continents are moving in opposite directions or whether one continent is stationary and the other is drifting away from it. Hot spots, anchored in the deeper layers of the earth, provide the measuring instruments needed to resolve the question. From an analysis of the hot spot population it appears that the African plate is stationary and that it has not moved during the past 30 million years.The significance of hot spots is not confined to their role as a frame of reference. It now appears that they also have an important influence on the geophysical processes that propel the plates across the globe. When a continental plate come to rest over a hot spot, the material rising from deeper layer creates a broad dome. As the dome grows, it develops seed fissures(cracks); in at least a few cases the continent may break entirely along some of these fissures, so that the hotspot initiates the formation of a new ocean. Thus just as earlier theories have explained the mobility of the continents, so hot spots may explain their mutability(inconstance).67.The author believes that _____ .A)the motion of the plates corresponds to that of the earth's interiorB)the geological theory about drifting plates has been proved to be trueC)the hot spots and the plates move slowly in opposite directionsD)the movement of hot spots proves the continents are moving apartEthnohistoric documents from sixteenth-century Mexico suggesting that weaving andcooking were the most common productive activities for Aztec women may leadmodern historians to underestimate the value of women's contributions to Aztecsociety. Since weaving and cooking occurred mostly (but not entirely) in a domesticsetting, modern historians are likely to apply to the Aztec culture the modern Western distinction between "private" and "public" production. Thus, the ethnohistoric recordconspires with Western culture to foster the view that women's production was notcentral to the demographic, economic, and political structures in sixteenth-centuryMexico.A closer examination of Aztec culture indicates that treating Aztec women's productionin Mexico in such a manner would be a mistake. Even if the products of women's labor did not circulate beyond the household, such products were essential to populationgrowth. Researchers document a tenfold increase in the population of the valley ofMexico during the previous four centuries, an increase that was crucial to thedeveloping Aztec political economy. Population growth--which could not haveoccurred in the absence of successful household economy, in which women's work was essential--made possible the large-scale development of labor-intensive chinampa(ridged-field) agriculture in the southern valley of Mexico which, in turn, supportedurbanization and political centralization in the Aztec capital.But the products of women's labor did in fact circulate beyond the household. Aztecwomen wove cloth, and cloth circulated through the market system, the tribute system, and the redistributive economy of the palaces. Cotton mantles served as a unit ofcurrency in the regional market system. Quantities of woven mantles, loincloths,blouses, and skirts were paid as tribute to local lords and to imperial tax stewards and were distributed to ritual and administrative personnel, craft specialists, warriors, and other faithful servants of the state. In addition, woven articles of clothing served asmarkers of social status and clothing fulfilled a symbolic function in politicalnegotiation. The cloth that was the product of women's work thus was crucial as aprimary means of organizing the flow of goods and services that sustained the Aztecstate.26The passage is primarily concerned with(A) using modern understanding of cultural bias to challenge ethnohistoric documents(B) evaluating competing descriptions of women's roles in Aztec society(C) comparing the influence of gender on women's roles in Aztec society and in modern society(D) remedying a potential misconception about the significance of women's roles in Aztec society(E) applying new evidence in a reevaluation of ethnohistoric documents。

But embarrassing scandals and the popularity of the republicans left in the recent Euro-elections have forced him to eat his words and stand down. So, does the Spanish crisis suggest that monarchy is seeing its last days? Does that mean the writing is on the wall for all European royals, with their magnificent uniforms and majestic lifestyles?The Spanish case provides arguments both for and against monarchy. When public opinion is particularly polarized, as it was following the end of the France regime, monarchs can rise above mere polities and embody a spirit of national unity.It is this apparent transcendence of polities that explains monarchys continuing popularity as heads of state. And so, the Middle East expected, Europe is the most monarch-infested region in the world, with 10 kingdoms (not counting Vatican City and Andorra). But unlike their absolutist counterparts in the Gulf and Asia, most royal families have survived because they allow voters to avoid the difficult search for a non-controversial but respected public figure.Even so, kings and queens undoubtedly have a downside. Symbolicof national unity as they claim to be, their very history-and sometimes the way they behave today-embodies outdated and indefensible privileges and inequalities. At a time when Thomas Piketty and other economists are warming of rising inequality and the increasing power of inherited wealth, it is bizarre that wealthy aristocratic families should still be the symbolic heart of modern democratic states.The most successful monarchies strive to abandon or hide their old aristocratic ways. Princes and princesses have day-jobs and ride bicycles, not horses (or helicopters). Even so, these are wealthy families who party with the international 1%, and media intrusiveness makes it increasingly difficult to maintain the right image.While Europes monarchies will no doubt be smart enough to survive for some time to come, it is the British royals who have most to fear from the Spanish example.It is only the Queen who has preserved the monarchys reputation with her rather ordinary (if well-heeled) granny style. The danger will come with Charles, who has both an expensive taste of lifestyle and a pretty hierarchical view of the world. He has failed tounderstand that monarchies have largely survived because they provide a service-as non-controversial and non-political heads of state. Charles ought to know that as English history shows, it is kings, not republicans, who are the monarchys worst enemies.21. According to the first two graphs, King Juan Carlos of Spain[A]eased his relationship with his rivals.[B]used to enjoy high public support.[C]was unpopular among European royals.[D]ended his reign in embarrassment.22. Monarchs are kept as head of state in Europe mostly[A]to give voters more public figures to look up to.[B]to achieve a balance between tradition and reality.[C]owing to their undoubted and respectable status.[D]due to their everlasting political embodiment.23. Which of the following is shown to be odd, according to graph 4?[A] The role of the nobility in modern democracies.[B] Aristocrats excessive reliance on inherited wealth.[C] The simple lifestyle of the aristocratic families.[D] The nobilitys adherence to their privileges.24. The British royals have most to fear because Charles[A]takes a tough line on political issues.[B]fails to change his lifestyle as advised.[C]takes republicans as his potential allies.[D]fails to adapt himself to his future role.25.

Mark your answers on the ANSWER SHEET.(40 points)Text 1France,which prides itself as the global innovator of fashion, has decided its fashion industry has lost an absolute right to define physical beauty for women. Its lawmakers gave preliminary approval last week to a law that would make it a crime to employ ultra-thin models on runways.The parliament also agreed to ban websites that “incite excessive thinness” by promoting extreme dieting.Such measures have a couple of uplifting motives. They suggest beauty should not be defined by looks that end up impinging on health. Thats a start. And the ban on ultra-thin models seems to go beyondprotecting models from starving themselves to deathas some have done. It tells the fashion industry that it must take responsibility for the signal it sends women, especially teenage girls, about the social tape-measure they must use to determine their individual worth.The bans, if fully enforced, would suggest to women (and many men) that they should not let others be arbiters of their beauty. And perhaps faintly, they hint that people should look to intangible qualities like character and intellect rather than dieting their way to size zero or wasp-waist physiques.The French measures, however, rely too much on severe punishment to change a culture that still regards beauty as skin-deepand bone-showing. Under the law, using a fashion model that does not meet a government-defined index of body mass could result in a $85,000 fine and six months in prison.The fashion industry knows it has an inherent problem in focusing on material adornment and idealized body types. In Denmark, the United States, and a few other countries, it is trying to set voluntary standards for models and fashion images that rely more on peer pressure for enforcement.In contrast to Frances actions, Denmarks fashion industry agreed last month on rules and sanctions regarding the age, health, and other characteristics of models. The newly revised Danish Fashion Ethical Charter clearly states: “We are aware of and take responsibility for the impact the fashion industry has on body ideals, especially on young people.” The charters main tool of enforcement is to deny access for designers and modeling agencies to Copenhagen Fashion Week, which is run by the Danish Fashion Institute. But in general it relies on a name-and-shame method of compliance.Relying on ethical persuasion rather than law to address the misuse of body ideals may be the best step. Even better would be to help elevate notions of beauty beyond the material standards ofa particular industry.21.According to the first paragraph, what would happen in France?[A] Physical beauty would be redefined.[B] New runways would be constructed.[C] Websites about dieting would thrive.[D] The fashion industry would decline.22.The phrase “impinging on” (Line 2,Para 2) is closest in meaning to[A] heightening the value of.[B] indicating the state of.[C] losing faith in.[D] doing harm to.23.Which of the following is true of the fashion industry?[A] The French measures have already failed.[B] New standards are being set in Denmark.[C] Model are no longer under peer pressure.[D] Its inherent problems are getting worse.24. A designer is most likely to be rejected by CFW for[A] setting a high age threshold for models.[B] caring too much about models character.[C] showing little concern for health factors.[D] pursuing perfect physical conditions.25.Which of the following may be the best title of the text?[A] The Great Threats to the Fashion Industry.[B] Just Another Round of Struggle for Beauty.[C] A Dilemma for the Starving Models in France.[D] A Challenge to the Fashion Industrys Body Ideals.。

She’s also cemented her foray into directing and now returns with YOLO. It’s her second major screen production, following a massive success in her directorial debut film Hi Mom in 2021.Jia Ling’s latest film has finally hit the big screen as part of the Spring Festival movies in 2024. But it’s not just the movie itself that’s causing a stir—it’s the 41-year-old actress’s stunning physical transformation. In the early teasers for YOLO, which follows a complete homebody who takes up boxing, audiences caught glimpses of Jia Ling’s dedication to her role as a boxer. She had shed an impressive 50kg (60 to be exact) in a span of six months. However, it wasn’t until the movie’s release that viewers truly got to witness the extent of her transformation.In the new poster for YOLO, viewers finally see a clear glimpse of Jia Ling’s fruits of labor. She reveals a toned figure after adopting a high-intensity fitness regimen that not only slimmed her down but also sculpted her physique. Jia Ling’s abs actually trended number one on the Weibo hot search. Despite having a slim figure in thepast, the actress-director gained prominence in the comedy scene, known to carry extra weight for years, making her recent transformation all the more remarkable.It’s not uncommon to see transformations for the sake of the storyline. Actors can wear prosthetics or others go the extra mile with extreme weight transformations. Jia Ling’s journey to shed weight was not just about slimming down; it was about building muscle and strength and she’s remained steadfast in her commitment. However, Jia Ling has been adamant that YOLO is not a film about weight loss. Instead, it’s a story about empowerment and self-discovery—a message that resonates deeply with audiences of all ages.【原创·阅读理解】1. What is the main focus of Jia Ling's latest film "YOLO"?A.

Half of the genomic data are from participants of non-European genetic ancestry.The unexplored cache of variants provides researchers with new pathways to better understand the genetic influences on health and disease, especially in communities who have been left out of research in the past, said the NIH.Nearly 4 million of the newly identified variants are in areas that may be tied to disease risk."As a physician, I've seen the impact the lack of diversity in genomic research has had in deepening health disparities and limiting care for patients," said Josh Denny, chief executive officer of the All of Us Research Program and an author of the study."The All of Us dataset has already led researchers to findings that expand what we know about health – many that may not have been possible without our participants' contributions of DNA and other health information. Their participation is setting a course for a future where scientific discovery is more inclusive, with broader benefits for all," Denny said.The mission of the All of Us Research Program is to accelerate health research and medical breakthroughs, enabling individualized prevention, treatment, and care for all, according to NIH.The program will partner with one million or more people across the United States to build the most diverse biomedical data resource of its kind, to help researchers gain better insights into the biological, environmental, and behavioral factors that influence health.【原创·阅读理解】1.

The Federal Communications Commission declared this month calls made with AI-generated voices are illegal.The task force report will include "guiding principles, forward-looking recommendations and bipartisan policy proposals developed in consultation with committees" in Congress.Jeffries said "the rise of artificial intelligence also presents a unique set of challenges and certain guardrails must be put in place to protect the American people."In October, Biden signed an executive order that aims to reduce the risks of AI. In January, the Commerce Department said it was proposing to require U.S. cloud companies to determine whether foreign entities are accessing U.S. data centers to train AI models.Representative Jay Obernolte, the Republican chair of the 24-member task force, said the report will detail "the regulatory standards and Congressional actions needed to both protect consumers and foster continued investment and innovation in AI."Democratic co-chair Ted Lieu Force said "the question is how to ensure AI benefits society instead of harming us."Earlier this month, Commerce Secretary Gina Raimondo said leading AI companies were among more than 200 entities joining a new U.S. consortium to support safe AI deployment including OpenAI, Alphabet's Google, Anthropic, Microsoft, Meta Platforms, Apple, and Nvidia.参考译文：美国众议院组建AI特别工作组美国众议院领导人周二表示，他们正在组建一个跨党派工作组，探讨解决人工智能（AI）问题的潜在立法。

大学英语四级（阅读）练习试卷8(题后含答案及解析) 题型有： 4. Reading Comprehension (Reading in Depth)Part IV Reading Comprehension (Reading in Depth) (25 minutes)Section BDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.The predictability of our mortality rates is something that has long puzzled social scientists. After all, there is no natural reason why 2,500 people should accidentally shoot themselves each year or why 7,000 should drown or 55,000 die in their cars. No one establishes a quota(配额) for each type of death. It just happens that they follow a consistent pattern year after year. A few years ago a Canadian psychologist named Gerald Wilde became interested in this phenomenon. He noticed that mortality rates for violent and accidental deaths throughout the Western world have remained oddly static throughout the whole of the century, despite all the technological advances and increases in safety standards that have happened in that time. Wilde developed an interesting theory called “risk homeostasis(自我平衡)”. According to this theory, people instinctively live with a certain level of risk. When something is made safer, people will get around the measure in some way to reassert the original level of danger. If, for instance, they are required to wear seat belts, they will feel safer and thus will drive a little faster and a little more recklessly, thereby statistically canceling out the benefits that the seat belt confers. Other studies have shown that where an intersection is made safer. the accident rate invariably falls there but rises to a compensating level elsewhere along the same stretch of road. it appears, then, that we have an innate need for danger. In all events, it is becoming clearer and clearer to scientists that the factors influencing our lifespan are far more subtle and complex than had been previously thought. It now appears that if you wish to live a long life, it isn’t simply a matter of adhering to certain precautions: eating the right foods, not smoking, driving with care. You must also have the fight attitude. Scientists at the Duke University Medical Center made a 15-year study of 500 persons’personalities and found, somewhat to their surprise, that people with a suspicious or mistrustful nature die prematurely far more often than people with a sunny disposition. Looking on the bright side, it seems, can add years to your life span.1．What social scientists have long felt puzzled about is ______.A．why a quota for each type of death has not come into beingB．why the mortality rate can not be predictedC．why the death toll remains stable year after yearD．why people lose their lives every year for this or that mason正确答案：C解析：细节题。
