托福阅读真题第318篇ClassStructuresinPostwarEurope(答案文章最后)lass Structures in Postwar EuropeRapid economic growth went a long way toward creating a new society in Europe after the Second World War. European society became more mobile and more democratic. Old class barriers relaxed, and class distinctions became fuzzier.hanges in the structure of the middle class were particularly influential in the general drift toward a less rigid class structure. In the nineteenth and early twentieth centuries, the model for the middle class had been the independent, self-employed individual who owned a business or practiced a liberal profession such as law or medicine. Ownership of property- -very often inherited property- -and strong family ties had often been the keys to wealth and standing within the middle class. fter 1945 this pattern declined drastically in Western Europe. new breed of managers and experts replaced traditional property owners as the leaders of the middle class. bility to serve the needs of a big organization largely replaced inherited property and family connections in determining an individual's social position in the middle and upper-middle classes. t the same time, the middle class grew massively and became harder to define.There were several reasons for these developments. Rapid industrial and technological expansion created a powerful demand for technologists and managers in large corporations and government agencies. Moreover, the old propertied middle class lost control of many family-owned businesses, and many small businesses simply went out of existence as their former owners joined the ranks of salaried employees. Top managersand ranking civil servants therefore represented the model for a new middle class of salaried specialists. Well paid and highly trained, often with backgrounds in engineering or accounting, these experts increasingly came from all social classes, even the working class. Pragmatic and realistic, they were primarily concerned with efficiency and practical solutions to concrete problems. Managers and technocrats, of whom a small but growing number were women, could pass on the opportunity for all-important advanced education to their children, but only in rare instances could they pass on the positions they had attained. Thus the new middle class, which was based largely on specialized skills and high levels of education, was more open, democratic, and insecure than the old propertied middle class.The structure of the lower classes also became more flexible and open. There was a mass exodus from farms and the countryside, as one of the most traditional and least mobile groups in European society drastically declined. Meanwhile, the industrial working class ceased to expand, and job opportunities for white-collar and service employees grew rapidly. Such employees bore a greater resemblance to the new middle class of salaried specialists than to industrial workers, who were also better educated and more specialized.European governments were reducing class tensions with a series of social security reforms. Many of these reforms-such as increased unemployment benefits and more extensive retirement pensions- simply strengthened social security measures first pioneered in Germany before the First World War. Other programs were new, such as comprehensive national health systems directed by the state. Most countries also introduced family allowances- direct government grants toparents to help them raise their children. These allowances helped many low-income families make ends meet. Most European governments also gave maternity grants and built inexpensive public housing for low-income families and individuals. These and other social reforms provided a humane level of well-being. Reforms also promoted greater equality because they were paid for in part by higher taxes on the rich.The rising standard of living and the spread of standardized consumer goods also worked to level European society, as the percent of income spent on food and drink declined substantially. For example, the European automotive industry expanded phenomenally after lagging far behind the United States since the 1920s. In 1948 there were only 5 million cars in Western Europe, but in 1965 there were 44 million. ar ownership was democratized and came within the range of better-paid workers. Europeans took great pleasure in the products of the gadget revolution as well. Like mericans, Europeans filled their houses and apartments with washing machines, vacuum cleaners, refrigerators, dishwashers, radios, televisions, and stereos. The purchase of consumer goods was greatly facilitated by installment purchasing, which allowed people to buy on credit. With the expansion of social security safeguards, reducing the need to accumulate savings for hard times, ordinary people were increasingly willing to take on debt.1.►Rapid economic growth went a long way toward creating a new society in Europe after the Second World War.

Answer the questions below each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1. (40 points)Text 1In the 2006 film version of The Devil Wears Prada ,Miranda Priestly, played by Meryl Streep, scolds her unattractive assistant for imagining that high fashion doesn’t affect her, Priestly explains how the deep blue color of the assistant’s sweater descended over the years from fashion shows to departments stores and to the bargain bin in which the poor girl doubtless found her garment.This top-down conception of the fashion business couldn`t be more out of date or at odds with the feverish would described in Overdressed, Elizabeth Cline`s three-year indictment of “fast fashion”. In the last decade or so, advances in technology have allowed mass-market labels such as Zara, H&M, and Uniqlo to react to trends more quickly and anticipate demand more precisely. Quicker turnarounds mean less wasted inventory, more frequent release, and more profit. These labels encourage style-conscious consumers to see clothes as disposable-meant to last only a wash or two, although they don’t advertise that –and to renew their wardrobe every few weeks. By offering on-trend items at dirt-cheap prices, Cline argues, these brands have hijacked fashion cycles, shaking an industry long accustomed to a seasonal pace.The victims of this revolution, of course, are not limited to designers. For H&M to offer a $5.95 knit miniskirt in all its 2,300-pius stores around the world, it must rely on low-wage overseas labor, order in volumes that strain natural resources, and use massive amounts of harmful chemicals.Overdressed is the fashion world`s answer to consumer-activist bestsellers like Michael Pollan`s. The Omnivore`s Dilemma. “Mass-produced clothing ,like fast food, fills a hunger and need, yet is non-durable and wasteful,”Cline argues. Americans, she finds, buy roughly 20 billion garments a year – about 64 items per person – and no matter how much they give away, this excess leads to waste.Towards the end of Overdressed, Cline introduced her ideal, a Brooklyn woman named Sarah Kate Beaumont, who since 2008 has made all of her own clothes –and beautifully. But as Cline is the first to note, it took Beaumont decades to perfect her craft; he r example can’t be knocked off.Though several fast-fashion companies have made efforts to curb their impact on labor and the environment –including H&M, with its green Conscious Collection line –Cline believes lasting change can only be effected by the customer. She exhibits the idealism common to many advocates of sustainability, be it in food or in energy. Vanity is a constant; people will only start shopping more sustainably when they can’t afford not to.21. Priestly criticizes her assistant for her[A] poor bargaining skill.[B] insensitivity to fashion.[C] obsession with high fashion.[D] lack of imagination.22. According to Cline, mass-market labels urge consumers to[A] combat unnecessary waste.[B] shut out the feverish fashion world.[C] resist the influence of advertisements.[D] shop for their garments more frequently.23. The word “indictment”(Line 3, Para.2) is closest in meaning to[A] accusation.[B] enthusiasm.[C] indifference.[D] tolerance.24. Which of the following can be inferred from the last paragraph?[A] Vanity has more often been found in idealists.[B] The fast-fashion industry ignores sustainability.[C] People are more interested in unaffordable garments.[D] Pricing is vital to environment-friendly purchasing.25. What is the subject of the text?[A] Satire on an extravagant lifestyle.[B] Challenge to a high-fashion myth.[C] Criticism of the fast-fashion industry.[D] Exposure of a mass-market secret.Text 2An old saying has it that half of all advertising budgets are wasted-the trouble is, no one knows which half. In the internet age, at least in theory, this fraction can be much reduced. By watching what people search for, click on and say online, compani es can aim “behavioral” ads at those most likely to buy.In the past couple of weeks a quarrel has illustrated the value to advertisers of such fine-grained information: Should advertisers assume that people are happy to be tracked and sent behavioral ads? Or should they have explicit permission?In December 2010 America's Federal Trade Commission (FTC) proposed adding a "do not track "(DNT) option to internet browsers ,so that users could tell advertisers that they did not want to be followed .Microsoft's Internet Explorer and Apple's Safari both offer DNT ;Google's Chrome is due to do so this year. In February the FTC and Digital Advertising Alliance (DAA) agreed that the industry would get cracking on responding to DNT requests.On May 31st Microsoft Set off the row: It said that Internet Explorer 10, the version due to appear windows 8, would have DNT as a default.It is not yet clear how advertisers will respond. Getting a DNT signal does not oblige anyone to stop tracking, although some companies have promised to do so. Unable to tell whether someone really objects to behavioral ads or whether they are sticking w ith Microsoft’s default, some may ignore a DNT signal and press on anyway.Also unclear is why Microsoft has gone it alone. After all, it has an ad business too, which it says will comply with DNT requests, though it is still working out how. If it is trying to upset Google, which relies almost wholly on default will become the norm. DNT does not seem an obviously huge selling point for windows 8-though the firm has compared some of its other products favorably with Google's on that count before. Brendon Lynch, MMicrosoft's chief privacy officer, blogged: "we believe consumers should have more control." Could it really be that simple?26. It is suggested in paragraph 1 that “behavioral”ads help advertisers to:[A] ease competition among themselves[B] lower their operational costs[C] avoid complaints from consumers[D] provide better online services27. “The industry”(Line 6,Para.3) refers to:[A] online advertisers[B] e-commerce conductors[C] digital information analysis[D] internet browser developers28. Bob Liodice holds that setting DNT as a default[A] many cut the number of junk ads[B] fails to affect the ad industry[C] will not benefit consumers[D] goes against human nature29. which of the following is true according to Paragraph.6?[A] DNT may not serve its intended purpose[B] Advertisers are willing to implement DNT[C] DNT is losing its popularity among consumers[D] Advertisers are obliged to offer behavioral ads30. The author's attitude towards what Brendon Lynch said in his blog is one of:[A] indulgence[B] understanding[C] appreciation[D] skepticismText 3Up until a few decades ago, our visions of the future were largely - though by no means uniformly - glowingly positive. Science and technology would cure all the ills of humanity, leading tolives of fulfillment and opportunity for all.Now utopia has grown unfashionable, as we have gained a deeper appreciation of the range of threats facing us, from asteroid strike to epidemic flu and to climate change. You might even be tempted to assume that humanity has little future to look forward to.But such gloominess is misplaced. The fossil record shows that many species have endured for millions of years - so why shouldn't we? Take a broader look at our species' place in the universe, and it becomes clear that we have an excellent chance of surviving for tens, if not hundreds, of thousands of years . Look up Homo sapiens in the "Red List" of threatened species of the International Union for the Conversation of Nature (IUCN) ,and you will read: "Listed as Least Concern as the species is very widely distributed, adaptable, currently increasing, and there are no major threats resulting in an overall population decline."So what does our deep future hold? A growing number of researchers and organizations are now thinking seriously about that question. For example, the Long Now Foundation has its flagship project a medical clock that is designed to still be marking time thousands of years hence.Perhaps willfully, it may be easier to think about such lengthy timescales than about the more immediate future. The potential evolution of today's technology, and its social consequences, is dazzlingly complicated, and it's perhaps best left to science fiction writers and futurologists to explore the many possibilities we can envisage. That's one reason why we have launched Arc, a new publication dedicated to the near future.But take a longer view and there is a surprising amount that we can say with considerable assurance. As so often, the past holds the key to the future: we have now identified enough of the long-term patterns shaping the history of the planet, and our species, to make evidence-based forecasts about the situations in which our descendants will find themselves.This long perspective makes the pessimistic view of our prospects seem more likely to be a passing fad. To be sure, the future is not all rosy. But we are now knowledgeable enough to reduce many of the risks that threatened the existence of earlier humans, and to improve the lot of those to come.31. Our vision of the future used to be inspired by[A] our desire for lives of fulfillment[B] our faith in science and technology[C] our awareness of potential risks[D] our belief in equal opportunity32. The IUCN`s “Red List”suggest that human being are[A] a sustained species[B] a threaten to the environment[C] the world`s dominant power[D] a misplaced race33. Which of the following is true according to Paragraph 5?[A] Arc helps limit the scope of futurological studies.[B] Technology offers solutions to social problem.[C] The interest in science fiction is on the rise.[D] Our Immediate future is hard to conceive.34. To ensure the future of mankind, it is crucial to[A] explore our planet`s abundant resources[B] adopt an optimistic view of the world[C] draw on our experience from the past[D] curb our ambition to reshape history35. Which of the following would be the best title for the text?[A] Uncertainty about Our Future[B] Evolution of the Human Species[C] The Ever-bright Prospects of Mankind[D] Science, Technology and HumanityText 4On a five to three vote, the Supreme Court knocked out much of Arizona's immigration law Monday-a modest policy victory for the Obama Administration. But on the more important matter of the Constitution, the decision was an 8-0 defeat for the federal government and the states.In Arizona, United States, the majority overturned three of the four contested provisions of Arizona's controversial plan to have state and local police enforce federal immigrations law. The Constitutional principles that Washington alone has the power to "establish a uniform Rule of naturalization" and that federal laws precede state laws are noncontroversial. Arizona had attempted to fashion state police that ran to the existing federal ones.Justice Anthony Kennedy, joined by Chief Justice John Roberts and the Court's liberals, ruled that the state flew too close to the federal sun. On the overturned provisions the majority held the congress had deliberately "occupied the field" and Arizona had thus intruded on the federal's privileged powersHowever, the Justices said that Arizona police would be allowed to verify the legal status of people who come in contact with law enforcement. That`s because Congress has always envisioned joint federal-state immigration enforcement and explicitly encourages state officers to share information and cooperate with federal colleagues.Two of the three objecting Justice-Samuel Alito and Clarence Thomas-agreed with this Constitutional logic but disagreed about which Arizona rules conflicted with the federal statute. The only major objection came from Justice Antonin Scalia, who offered an even more robust defense of state privileges going back to the alien and Sedition Acts.The 8-0 objection to President Obama turns on what Justice Samuel Alito describes in his objection as “a shocking assertion of federal executive power”. The White House argued the Arizona`s laws conflicted with its enforcement priorities, even if state laws complied with federal statutes to the letter. In effect, the White House claimed that it could invalidate any otherwise legitimate state law that it disagrees with.Some powers do belong exclusively to the federal government, and control of citizenship and the borders is among them. But if Congress wanted to prevent states from using their own resources to check immigration status. It never did so. The administration was in essence asserting that because it didn't want to carry out Congress's immigration wishes, no state should be allowed to do so either. Every Justice rightly rejected this remarkable claim.36. Three provisions of Arizona`s plan were overturned because they[A] deprived the federal police of Constitutional powers.[B] disturbed the power balance between different states.[C] overstepped the authority of federal immigration law.[D] contradicted both the federal and state policies.37. On which of the following did the Justices agree, according to Paragraph4?[A] Federal officers` duty to withhold immigrants` information.[B] States` independence from federal immigration law.[C] States` legitimate role in immigration enforcement.[D] Congress`s intervention in immigration enforcement.38. It can be inferred from Paragraph 5 that the Alien and Sedition Acts[A] violated the Constitution.[B] undermined the states` interests.[C] supported the federal statute.[D] stood in favor of the states.39. The White House claims that its power of enforcement[A] Outweighs that held by the states.[B] is dependent on the states` support.[C] is established by federal statutes.[D] rarely goes against state laws.40. What can be learned from the last paragraph?[A] Immigration issues are usually decided by Congress.[B] Justices intended to check the power of the Administration.[C] Justices wanted to strengthen its coordination with Congress.[D] The Administration is dominant over immigration issues.Part BDirections:In the following text, some sentences have been removed.

Mark your answers on ANSWER SHEET1.(10 points)The social sciences are flourishing. As of 2005, there were almost half a million professional socialscientists from all fields in the world, working both inside and outside academia. According to the World Social Science Report 2010, the number of social-science students worldwide has swollen by about 11% every year since 2000.Yet this enormous resource in not contributing enough to today`s global challenges including climate change, security, sustainable development and health.(41)______Humanity has the necessary agro-technological tools to eradicate hunger , from genetically engineered crops to artificial fertilizers . Here, too, the problems are social: the organization and distribution of food, wealth and prosperity.(42)____This is a shame—the community should be grasping the opportunity to raise its influence in the real world. To paraphrase the great social scientist Joseph Schumpeter: there is no radical innovation without creative destruction.Today, the social sciences are largely focused on disciplinary problems and internal scholarly debates, rather than on topics with external impact.Analyses reveal that the number of papers including the keywords “environmental changed”or “climate change”have increased rapidly since 2004,(43)____When social scientists do tackle practical issues, their scope is often local: Belgium is interested mainly in the effects of poverty on Belgium for example .And whether the community’s work contributes much to an overall accumulation of knowledge is doubtful.The problem is not necessarily the amount of available funding (44)____this is an adequate amount so long as it is aimed in the right direction. Social scientists who complain about a lack of funding should not expect more in today`s economic climate.The trick is to direct these funds better. The European Union Framework funding programs have long had a category specifically targeted at social scientists. This year, it was proposed that system bechanged: Horizon 2020, a new program to be enacted in 2014, would not have such a category. This has resulted in protests from social scientists. But the intention is not to neglect social science; rather, the complete opposite. (45)____That should create more collaborative endeavors and help to develop projects aimed directly at solving global problems.[A] It could be that we are evolving two communities of social scientists: one that is discipline-oriented and publishing in highly specialized journals, and one that is problem-oriented and publishing elsewhere, such as policy briefs.[B] However, the numbers are still small: in 2010, about 1,600 of the100,000 social-sciences papers published globally included one of these keywords.[C] The idea is to force social to integrate their work with other categories, including health and demographic change food security, marine research and the bio-economy, clear, efficient energy; and inclusive, innovative and secure societies.[D] The solution is to change the mindset of the academic community, and what it considers to be its main goal. Global challenges and social innovation ought to receive much more attention from scientists, especially the young ones.[E] These issues all have root causes in human behavior. All require behavioral change and social innovations, as well as technological development. Stemming climate change, for example, is as much about changing consumption patterns and promoting tax acceptance as it is about developing clean energy.[F] Despite these factors, many social scientists seem reluctant to tackle such problems. And in Europe, some are up in arms over a proposal to drop a specific funding category for social-science research and to integrate it within cross-cutting topics of sustainable development.[G] During the late 1990s , national spending on social sciences and the humanities as apercentage of all research and development funds-including government, higher education, non-profit and corporate -varied from around 4% to 25%; in most European nations , it is about 15%. Part CDirections: Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written clearly on ANSWER SHEET 2. (10 points) It is speculated that gardens arise from a basic need in the individuals who made them: the need for creative expression. There is no doubt that gardens evidence an impossible urge to create, express, fashion, and beautify and that self-expression is a basic human urge; (46) Yet when one looks at the photographs of the garden created by the homeless, it strikes one that, for all their diversity of styles, these gardens speak of various other fundamental urges, beyond that of decoration and creative expression.One of these urges had to do with creating a state of peace in the midst of turbulence, a “still point of the turning world,”to borrow a phrase from T. S. Eliot. (47)A sacred place of peace, however crude it may be, is a distinctly human need, as opposed to shelter, which is a distinctly animal need. This distinction is so much so that where the latter is lacking, as it is for these unlikely gardens, the former becomes all the more urgent. Composure is a state of mind made possible by the structuring of one’s relation to one’s environment. (48) The gardens of the homeless which are in effect homeless gardens introduce from into an urban environment where it either didn’t exist or was not discernible as such. In so doing they give composure to a segment of the inarticulate environment in which they take their stand.Another urge or need that these gardens appear to respond to, or to arise from is so intrinsic that we are barely ever conscious of its abiding claims on us. When we are deprived of green, of plants, of trees, (49) most of us give into a demoralization of spirit which we usually blame on some。

All rights reserved.1.IntroductionMagnetic core–shell Fe 3O 4@SiO 2nanoparticles as specially immobilizing carrier of biomolecules have aroused great interest in current researches.The inner iron oxide core with outer shell of silica not only stabilizes the nanoparticles in solution but also provides sites for surface modification with various biomedical ligands in biomedical applications.The coating of silica on the mag-netic nanoparticles facilitated the dispersion of nanoparticles [1,2].Due to their unique physical,chemical,and mechanical proper-ties,superparamagnetic composite nanoparticles (NPs)hold much promise for biosensor applications [3–5].Superparamagnetic iron oxide core of individual NPs becomes more efficient at dephasing the spins of surrounding water protons,enhancing spin–spin relax-ation times (T 2relaxation times)so that the NPs act as magnetic relaxation switches (MRS)[6].Carbon nanotubes (CNTs)are one ofthe most studied nanomaterials for application in biosensor tech-nologies,by immobilizing bioactive molecules on their surfacesthrough covalent or non-covalent bonds.The nanodimensions ofCNTs guarantee a very large active surface area and are especially∗Corresponding author.Tel.:+914422574862;fax:+914422570509.E-mail address:ramp@iitm.ac.in (S.Ramaprabhu).suited for the conception of miniaturized sensors.In addition tothis,high porosity and reactivity makes them ideal candidates forthe storage of neutral species as well as electron donors when used as electrodes in electrochemical reactions [7–9].Compared with the corresponding CNTs-free biosensor,theCNTs-doped counterpart exhibited enhanced stability and sensitiv-ity.Surface functionalization aids CNTs to become biocompatible,improving their solubility in physiological solutions and selectivebinding to Ts functionalization with biomolecules may occur by adsorption,but covalent tethering provides betterstability,accessibility,selectivity and reduced leaching,and usually occurs by an amidation reaction [10].CNTs are also used for dra-matically amplifying enzyme-based bioaffinity electrical sensing ofproteins and DNA [11].Compared with single walled nanotubes(SWNTs),much cheaper multiwalled nanotubes (MWNTs)pro-duced by chemical vapour deposition have more structural defects and thus provide more sites for biomolecule immobilization [8].Non-covalently functionalized CNTs may also immobilize glucose and small molecules [12].Nanocomposite materials may play an important role for improving functionalized electrodes envisaging commercial appli-cations.Nanoparticles,especially metal nanoparticles,are an emerging issue in biosensor design,and they have been combined with CNTs to modify a glassy carbon electrode,thus improving the 0039-9140/$–see front matter © 2009 Elsevier B.V.

applications, due to their superior stability and complete recovery in biochemical redox processes.However,other groups showed that immobiliza-tion of the Au nanoparticles(or other metal nanoparticles)on the electrode surface would also cause similar catalytic effect on the electrochemical responses.Amperometric detection of glucose was developed using Au nanoparticles and CNT-multilayer membranes [14].An electrochemical study with cyclic voltammetry and impedance analysis confirmed that glucose oxidase molecules suffer minimal structure changes after being immobilized on the surface of CNTs,retaining the ability to interact with small biomolecules(e.g.,ethidium bromide)[7].In this present study, MWNTs functionalized with nitric acid,in order to introduce carboxylic acid groups,have been used for the preparation of Fe3O4@SiO2/MWNTs-based electrodes.Prior to immobiliza-tion,glucose oxidase(GOD)was physically adsorbed on these modified electrodes.Here,we show a good performance,fast response,nice stability and reproducibility,and a low detec-tion limit of Fe3O4@SiO2/MWNTs nanocomposite based on the reduction of H2O2by immobilizing glucose oxidase on the composite.2.Experimental2.1.MaterialsGlucose oxidase(GOD,from Aspergillus niger),tetraethoxysi-lane(TEOS)were purchased from Sigma.0.1M phosphate buffer solution(PBS,pH7)prepared using potassium phosphate diba-sic anhydrous and potassium dihydrogen orthophosphate.Ferric chloride(FeCl3·6H2O),ferrous sulphate(FeSO4·7H2O),ethanol and ammonium hydroxide(25%)were of analytical grade and deionised (dI)water was used throughout.2.2.Sample preparationCarbon nanotubes were synthesized by catalytic chemical vapour deposition over an alloy hydride catalyst.Rare earth based AB3alloy hydride was made by arc melting followed by sev-eral cycle of hydrogen absorption/desorption process.The catalyst was kept inside a furnace and acetylene(carbon precursor)was allowed at a temperature range650–750◦C,in an inert atmo-sphere.Pyrolysis of acetylene was taken place at that temperature and MWNTs start growing.The as-grown MWNTs were puri-fied before using for any applications.The amorphous carbon can be removed by heating the as-grown sample in oxygen atmo-sphere.Refluxing in concentric acids has been shown to beanFig. 2.X-ray diffractograms of(a)pure MWNTs,(b)Fe3O4/MWNTs and(c)

func-tionalized MWNTs dissolved in 50ml of water,were added rapidly and sequentially.The mixture was stirred at 90◦C for 30min and then cooled to room temperature.The black precipitate was col-lected by filtrating and washed to neutral with water.The obtained black precipitate was Fe 3O 4/MWNT nanoparticles and was ready for use.Core–shell Fe 3O 4@SiO 2/MWNT nanoparticles were prepared by growing silica layers onto the surface of the Fe 3O 4/MWNTs as described by Lu et al.[16].Twenty-five milliliters of ethanol,1ml water,1ml ammonium hydroxide and 150l of TEOS were added in a 250ml three neck flask in a 40◦C water bath.Add Fe 3O 4/MWNTs to the above solution under mechanical stirring.Aliquots of the mixture were takes out after 12h by centrifugation and washed with dI water and vacuum-dried at 50◦C overnight.Fig.4.VSM study of Fe 3O 4/MWNTs (red line)and Fe 3O 4@SiO 2/MWNTs (black line).(For interpretation of the references to color in this figure legend,the reader is referred to the web version of the article.)2.3.Fabrication of the amperometric immunosensorThe GCE (3-mm diameter)was first polished on chamois leather with 0.05-m alumina slurry and then washed ultrasonically in doubly distilled water,anhydrous ethanol,and doubly distilled water,respectively.The cleaned GCE was allowed to dry at room temperature.Fe 3O 4@SiO 2/MWNTs was sonicated in 0.5%Nafion solution to give a concentration of ∼1mg/ml.For example,four micro-liters of the Fe 3O 4@SiO 2/MWNTs suspension was film-cast onto the surface of the GC electrode and allowed to dry slowly.Films formed from Nafion-solubilized MWNTs are more uni-form and stable than those cast from organic solvents.Nafion assists the dispersion of Fe 3O 4@SiO 2/MWNTs,whereby the Fe 3O 4@SiO 2/MWNTs remains well dispersed on prolonged stand-ing.16l of 100U GOD solution was film-cast onto the surface of the Fe 3O 4@SiO 2/MWNTs/GC electrode and allowed to dry slowly at 4◦C.The obtained Fe 3O 4@SiO 2/MWNTs/GC electrode was washed carefully with DI water and dried at less than 4◦C.Fig.1shows the schematic of fabrication of Fe 3O 4@SiO 2/MWNTs/GC electrode.These Fe 3O 4@SiO 2/MWNTs/GC electrodes were coated with an extra 2.5l layer of 0.5%Nafion.The electrodes were rinsed with pH 7phosphate buffer solution (PBS)and stored in the buffer at 4◦C prior to use.2.4.Characterization methodsThe electrochemical measurements were performed with CH Instruments CHI 608C Electrochemical Analyzer/Workstation.A platinum wire counter electrode,Ag/AgCl (3M KCl)reference elec-trode and glassy carbon electrode (GCE,diameter 3mm)were inserted into a modified 5–10ml glass cell for the measurement.All potentials are referred to the Ag/AgCl reference electrode.The samples were characterized using different techniques.Powder X-ray diffraction studies were carried out using a X’Pert PRO,PAN-alytical diffractometer with nickel-filtered Cu K ␣radiation as the X-ray source.The sample was scanned in steps of 0.016◦in the 2Ârange 10–90◦.Identification and characterization of functional groups were carried out using PerkinElmer FT-IR spectrometer in the range 300–4000cm −1.The surface morphology of the sam-ple was done by using scanning tunneling microscope (SEM)(FEI;QUANTA scanning electron microscope)with EDX system.The EDX system attached with the SEM enables the elemental analysis of the samples.The TEM images were obtained on a transmission electron microscope (TEM,JEOL JEM-2010F).UV absorption spectra of the samples in deionized water were recorded on JASCO Corp.,V-570spectrophotometer.Magnetic study of the samples had been done by vibrating sample magnetometer (VSM).3.Results and discussion3.1.XRD and FT-IR studies of the samplesThe XRD pattern in Fig.2indicates that the crystal structure of magnetic nanocomposites comprises MWNTs,two phases of cubic Fe 3O 4/MWNTs and Fe 3O 4@SiO 2/MWNTs.Well-resolved diffraction peaks reveal the good crystallinity of the Fe 3O 4specimens,which are located at 2Âof 30.28◦,35.56◦,43.3◦,53.68◦,57.36◦and 62.72◦,respectively.These data matched well with the peer Ref.[17].The peaks in the Fe 3O 4@SiO 2/MWNTs reveal that even after the SiO 2coating the sample retains its crystallinity [18].The absence of SiO 2peak in the XRD pattern in the composite is due to its amorphous structure coated on the Fe 3O 4nanoparticles.The diffraction peak at 2Â=26.4◦is the typical Bragg peak of pristine MWNTs and can be indexed to the (002)reflection of graphite.Judging from the pat-T.T.Baby,S.Ramaprabhu

described by D =0.9 ˇcos(Â)(1)is wave length of X-ray used,ˇis FWHM of diffraction peak and Âangle corresponding to the peak.The calculated average grain sizes using 35.56◦diffraction peak were ∼25nm.Moreover,the diffrac-tive peaks of Fe 3O 4are broadened,implying that the crystalline size of Fe 3O 4particles is quite small.Selectivity of MWNTs-based biosensors may be introduced by anchoring on the MWNTs surface,specific functional groups that selectively bind specific target molecules.All types of MWNTs show peaks between 1300and 1100cm −1,which are ascribed to the phenyl-carbonyl C–C stretch bonds (Fig.3(a)).The peak between 3300–3500cm −1is normally due to stretching vibration mode of OH and NH group.The peak at 3457cm −1in curve (a)and curve (b)is due to OH group (due to oxidation with HNO 3)and in curve (c)it is due to both OH and –NH (from ammonia solution).One can see a small broadening of this peak in the case of curve (c).As seen from Fig.3(b),the peak at 568cm −1is the stretching vibration due to the interactions of Fe–O–Fe in Fe 3O 4and the peaks at 1383,2850and 2928cm −1are attributed to the in-plane bending vibra-tion of methyl (–CH 3)and the symmetric and asymmetric vibration of methylene (–CH 2–).Compared with the two spectra (b and c),the existence of the characteristic Si–O–Si peak at 1080cm −1in Fig.3(c)is direct evidence to verify the formation of the silica shell.From Fig.3(b)and (c),we can also see that the characteristic Fe–O–Fe peak of Fe 3O 4/MWNTs at 568cm −1shift to 580cm −1in the spec-trum of SiO 2coated magnetic nanoparticles.It is inferred that the silica shell is linked to the surface of the magnetic nanoparticles by a Fe–O–Si chemical bond [19].It is generally accepted that the inter-pretation of surface groups can only be qualitative,as they cannot be expected to behave as isolated functional groups [20].Fig.6.TEM image of (A)pure MWNTs,(B)Fe 3O 4@SiO 2/MWNTs,(C)SEM image of pure MWNTs and (D)EDX for Fe 3O 4@SiO 2/MWNTs.2020T.T.Baby,S.Ramaprabhu /Talanta80 (2010) 2016–2022Fig.7.(A)Fe 3O 4@SiO 2/MWNTs modified electrode at different scan rates in PBS (0.1M,pH 7)and (B)the plot of peak anodic peak current vs.v 1/2.3.2.Magnetic and optical studies of samplesFig.4exhibits the hysteresis loop of the as-prepared sample at room temperature.It can be seen that the saturation magneti-zation of Fe 3O 4@SiO 2/MWNTs (∼44emu/g)is almost comparable to that of Fe 3O 4/MWNTs (∼46emu/g),which indicates that Fe 3O 4nanoparticles covered by a silica network can preserve their super-paramagnetic properties.The UV–vis absorption spectrum of different samples in deion-ized water is illustrated in Fig.5.A very broad absorption peak appeared at about 267nm,which originated from the C C struc-ture of MWNTs [21].The optical properties of all the magnetic nanoparticles used (with or without silica coating)are dominated by a broad featureless absorption tail characteristic of indirect band gap semiconductors.In the wavelength of >330nm region,a broad featureless adsorption could be observed in the curves with SiO 2and without SiO 2originates primarily from the absorption and scat-tering of light by magnetic particles,which is in accordance with the previous literatures [22],and is the characteristic of indirect band gap semiconductors [23].3.3.SEM and TEM analysis of the samplesThe morphology of the purified MWNTs is clearly visible from the SEM image shown in Fig.6(C).Fig.6(A and B)illus-trates the TEM images of the synthesized MWNTs and prepared Fe 3O 4@SiO 2/MWNTs core–shell nanoparticles.The open end of the MWNTs are clearly visible from the TEM image.The diame-ter of the MWNTs is ∼25nm.With the help of references [24,25]and the TEM and EDX shown in Fig.6(B and D)we can see that the sample is nearly in core–shell structures,with black color shows Fe 3O 4and ash color is the SiO 2shell.This indicates the successful coating on the surface of the magnetic particles with silica.The EDX shown in Fig.6(D)confirms the presence of iron and silicon in the sample.Inorganic compound func-tionalized iron oxide NPs can greatly enhance the antioxidation properties for naked iron oxide NPs,and its corresponding scope of application has been greatly extended.Moreover,inorganic compounds functionalized iron oxide NPs are very promis-ing for application in catalysis,biolabeling,and bioseparation [26].Fig.8.(A)displays the CV of the Fe 3O 4@SiO 2/MWNTs modified electrode (a)in PBS (b)with 0.3mM H 2O 2and (c)15mM glucose solution and (B)study of interference due to ascorbic acid and uric acid with and without a selective Nafion film on the GOD/Fe 3O 4@SiO 2/MWNTs modified electrode.T.T.Baby,S.Ramaprabhu/Talanta80 (2010) 2016–202220213.4.Cyclic voltammetry and electrocatalytic properties of theGOD/Fe3O4@SiO2/MWNTs modified electrode toward hydrogen peroxideCyclic voltammetry peak currents of the GOD/ Fe3O4@SiO2/MWNTs modified electrode increased with scan rate and the peak separation( E p)was nearly independent of the scan rate(Fig.7(A)).The anodic peak currents increased linearly with the increase of the square root of scan rate,suggesting that the electrochemical reaction is a diffusion-controlled process (Fig.7(B)).Fig.8(A)shows the cyclic voltammograms of the GOD/ Fe3O4@SiO2/MWNTs/GC electrode in the absence(curve a),in the presence of0.3mM H2O2(curve b)and in15mM glucose solution(curve c).The GOD/Fe3O4@SiO2/MWNTs/GC electrode exhibits significant electrocatalysis to the oxidation and reduc-tion of H2O2starting around0.1V,which is even lower than that obtained with the GOD/MWNTs electrode by covalent binding immobilization(0.2V)[27].The good performance of the fabricated GOD/Fe3O4@SiO2/MWNTs/GC electrode toward the oxidation of H2O2makes it attractive for glucose sensing applications.When MWNTs were treated with the acid solution,the carboxylic acid functional groups introduced at the end points and surface of MWNTs allow them to adsorb the enzyme of GOD.Since this adsorption was fulfilled through a covalent bond,the link between MWNTs and GOD was more close and stable.Moreover,because the MWNTs have large surface area,they could enhance a large amount of GOD to be immobilized within the nanotubes.The more quan-tity of GOD made the biosensor possible to engender high response current and expand the detectable range when in a glucose solution.3.5.Effect of electroactive interferentsThe interference of some electroactive compounds to the glu-cose response was examined.To study this we added0.2mM of ascorbic acid(AA)and uric acid(UA)to the solution and checked the GOD/Fe3O4@SiO2/MWNTs/GC electrode with Nafion coating and without Nafion coating.The upper curve in Fig.8(B)which had been done without Nafion shows the presence of AA and UA.The lower curve in Fig.8(A)shows the interference study with Nafion coated GOD/Fe3O4@SiO2/ MWNTs/GC electrode.There is not much change in the current due to AA and UA.Which clearly shows that2.5l of0.5wt%Nafion on the surface of GOD/Fe3O4@SiO2/MWNTs/GC electrode prevent the interference.3.6.Study of amperometric i–t and calibration curveThe amperometric responses at the GOD/Fe3O4@SiO2/ MWNTs/GC electrode for successive addition of different concentration of glucose are presented in Fig.9(inset).Well-defined current responses for glucose were obtained at the GOD/Fe3O4@SiO2/MWNTs/GC electrode.The reaction occurring at the biosensor is very fast in reaching a dynamic equilib-rium upon each addition of the sample solution,generating a steady-state current signal within3–ing the optimum conditions established in the above studies,the calibration of the GOD/Fe3O4@SiO2/MWNTs/GC electrode is depicted in Fig.9. The steady-state currents gradually increased with increasing concentration of glucose,and exhibited a linear relationship with the concentration of glucose in the range from1M to 30mM with a detection limit of800nM(estimated at S/N=3) with a correlation coefficient of0.9994.The performance of GOD/Fe3O4@SiO2/MWNTs/GC electrode is superior than the reported value of GOD/Fe3O4@SiO2/GC electrode which ishaving Fig.9.The calibration curve of the fabricated GOD/Fe3O4@SiO2/MWNTs/GC elec-trode.Amperometric i–t curve with addition of different concentration of glucose solution(inset).a linear range1.0×10−5to4.0×10−3M with a detection limit of3.2M[28].From Fig.9,it was observed that the biosensor response gradu-ally deviates from the linear feature as the glucose concentration up to30mM.This is the characteristic of a typical Michaelis–Menten kinetics.The apparent Michaelis–Menten constant K app m,which depicts the enzyme–substrate kinetics of biosensor,can be calcu-lated from the Line weaver–Burk equation:1I ss=K app mI max1C+1I max(2) where C is the concentration of substrate,I ss is the steady-state current and I max is the maximum current measured under sub-strate saturation[29].Therefore the values of the K app m and I max in this work can be calculated to be13mM and25A,respec-tively.The lower K app m means the higher enzymatic activity of immobilized GOD thus the above result further indicates that the Fe3O4@SiO2/MWNTs modified biosensor possesses a high affinity to glucose[30].Since MWNTs have excellent electrical conductivity,MWNTs as well as iron oxide dispersed MWNTs attached to the protein shell of enzyme could improve the transfer of electrons between the active redox center of the enzyme.This effect could accelerate the regen-eration of GOD and increase the relative activity of the enzyme finally.It is thought to be the mean reason of why the current response of MWNTs and iron oxide dispersed MWNTs modified glucose biosensor was higher than that of the other biosensors.4.ConclusionFe3O4nanoparticles can be successfully stabilized by SiO2 and Fe3O4@SiO2/MWNTs can be deposited on GCE.GOD can be effectively immobilized on Fe3O4@SiO2/MWNTs/GC electrode to produce a fast direct electron transfer.The immobilized GOD main-tains its bioactivity and native structure.Its reduced form can be oxidized by dissolved oxygen to cause an electrocatalytic reaction, which is restrained by glucose due to the reaction between the oxidized form of GOD and glucose.Based on the decrease of electro-catalytic response,a novel glucose sensor has been developed and the resulting sensor displays a high sensitivity(58.9A/mM cm2) and a linear range from1M to30mM for glucose determination, and can efficiently exclude the interference of commonly coexisted uric and ascorbic acid.Because of its convenient preparation and2022T.T.Baby,S.Ramaprabhu/Talanta80 (2010) 2016–2022good properties,this biosensor can be used for glucose determina-tion in food industries.AcknowledgementsThe authors acknowledge the funding AOARD,USA and Indian Institute of Technology

英语六级历年阅读题及答案
2010年6月阅读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 and mark the corresponding letter on Answer Sheet2 with a single line through the centre.Passage OneQuestions 51 to 56 are based on the following passage.Only two countries in the advanced world provide no guarantee for paid leave from work to care for a newborn child. Last spring one of the two, Australia, gave up the dubious distinction by establishing paid family leave starting in 2011. I wasn't surprised when this didn't make the news here in the United States—we're now the only wealthy country without such a policy.The United States does have one explicit family policy, the Family and Medical Leave Act, passed in 1993. It entitles workers to as much as 12 weeks' unpaid leave for care of a newborn or dealing with a family medical problem. Despite the modesty of the benefit, the Chamber of Commerce and other business groups fought it bitterly, describing it as "government-run personnel management" and a "dangerous precedent". In fact, every step of the way, as (usually) Democratic leaders have triedto introduce work-family balance measures into the law, business groups have been strongly opposed.As Yale law professor Anne Alstott argues, justifying parental support depends on defining the family as a social good that, in some sense, society must pay for. In her book No Exit: What Parents Owe Their Children and What Society Owes Parents, she argues that parents are burdened in many ways in their lives: there is "no exit" when it comes to children. "Society expects—and needs—parents to provide their children with continuity of care, meaning the intensive, intimate care that human beings need to develop their intellectual, emotional and moral capabilities. And society expects—and needs—parents to persist in their roles for 18 years, or longer if needed."While most parents do this out of love, there are public penalties for not providing care. What parents do, in other words, is of deep concern to the state, for the obvious reason that caring for children is not only morally urgent but essential for the future of society. The state recognizes this in the large body of family laws that govern children' welfare, yet parents receive little help in meeting the life-changing obligations society imposes. To classify parenting as a personal choice for which there is no collective responsibility is not merely to ignore the social benefits of good parenting; really, it is to steal those benefits because they accrue (不断积累) to the whole of society as today's children become tomorrow'sproductive citizenry (公民). In fact, by some estimates, the value of parental investments in children, investments of time and money (including lost wages), is equal to 20-30% of gross domestic product. If these investments generate huge social benefits—as they clearly do—the benefits of providing more social support for the family should be that much clearer.注意:此部分试题请在答题卡2上作答。

Then head north. Will Steger is going to take all of us there. Steger, 64, the first person to make a dogsled trip to the Noah Pole, is a very famous and admired polar explorer. He's at home in frozen parts of the world where few humans ever step on. Steger is also a devoted environmentalist who was early to ring the alarm bell on global warming. He saw its effects firsthand in frequent polar expeditions to the Arctic and Antarctica.Steger is about to lead a team of six young adventurers on a 1,400-mile,60-day-long dogsled trip across Ellesmere Island, in the Canadian Arctic. The sea ice in that region should still be frozen. "We want to take our audience to the front lines of global warming, "says Steget. The team will be uploading videos, stories and photos to the website global-warming, com as they march along, allowing armchair adventurer's and kids in classrooms to follow their progress day to day. "We can actually bring the audience up there," Steger says.Steger's team will include some already-famous young explorers. Sam Branson, the 22- year-old son of British airline tycoon(大亨)Richard Branson, is an experienced Arctic traveler. Also on the journey will be 27-year-old Norwegian Sigrid Ekran. Last year, Ekran became only the second woman in history to win Rookie(新秀)of the Year for the Iditarod Sled Dog Race. What they will see may be surprising. Even Steger doesn't know exactly what to expect. Climate change has already reshaped the geography of the Arctic, "Within a decade or less, it's goingto be impossible to reach the North Pole by dog team, without flotation (漂流),"says Steger. Climate change is happening, but people can change too. Their willingness to change will determine the shape of Earth's future. Steger is about to organize the adventure to the Arctic in order to→ ←.A. let more people enjoy its natural beautyB. collect evidence for his scientific researchC. let people realize the bad effects of global warmingD. develop the young people's adventurous and brave spirit3.(单项选择题)(每题 2.00 分) Which of the following sets of English sounds differs only in one distinctive feature?→ ←A.

Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual——the sort of environment in which he is brought up. if an individual is handicappedenvironmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.The importance of environment in determining an individual’s intelligence can be demonstrated by the ease history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster homes. Peter was raised by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to me asure their intelligence. Mark’s I.Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level. The case history of the twins appears to support the conclusion that→ ←A. individuals with identical brains seldom test at the same levelB. an individual’s intelligence is determined only by his environmentC. lack of opportunity blocks the growth of intelligenceD. changes of environment produce changes in the structure of the brain6.(单项选择题)(每题 2.00 分) Passage TwoRespect is not included in the marriage vows. No illustrated books show how to achieve it. And yet it is central to a lasting, satisfying marriage.What is this thing called respect? It is not the same as admiration. "When you fall in love, you admire the other, "says Dr. Alexandra Symonds, associate clinical professor of psychiatry at the New York University, School of Medicine.” You look up to someone-much the way a child idealizes a parent.”Such romantic admiration thrives and even depends on the illusion that he or she is "perfect for you.95 Thafs why it doesnt last. "You come to see that the person you married isnt exactly what you expected.", says Francine Klagsbrun. "There are differences of personality, of approaches to life, different ways of doing things. ”You can try to change your mate back into your fantasy. But for the marriage to last and grow its better to →agree to disagree←, to learn to let each other be. Only by taking this path can you begin to develop real respect toward each other.“I have one patient whose husband loves sports,especially tennis,”says Dr. Symonds.” She would prefer to go to the theatre, or to stay at home and read. She could simply say, ‘We have different tastes.’ Instead, she says, How can he waste his time and money that way? She puts him down."The put-down is the chief symptom and weapon of lack of respect or contempt. "Contempt is the w orst kind of emotion.” says Symonds. "You feel the other person has no worth.’ We’ve all seen marriages in which one or both partners attack the other quite savagely in the guise of Its for your own good. Any "good" is→ undone ←by the hostile tone. A wife nags her husband to be more ambitious and makes him feel like a failure because he prefers craftsman- ship or community projects to the competitive business world. Or a husband accuses his wife of wasting time whenever she gets together with a friend. "Why isnt she doing something productive?"In good marriage partners nurture each others self-esteem. They may express humorous incomprehension of one anothers preferences, but they never make the other person feel like an idiot. "Martyrs idea of a vacation is to go down to the basement on a sunny day and spend time woodworking, "says Dr. Alexandra Symonds of her husband, psychiatrist and surgeon Martin Symond.But theres fondness in the gibes and firm support for the others right to be himself. Respect is expressed in words like. ul dont want to go to the concert, but you have a great And occasionally, "Sure, III come with you. Just dont him angry if I fall asleep. " Respect, then is appreciation of the separateness of the other person, of the ways in which he or she is unique. These things take time to discover and accept.Thats the paradox of a good marriage: only by respecting each other as you are do you open the door to change. The root meaning of the word respect is "to look at". Respect is a clear yet loving eye. It sees what is really there, but it also sees what is potentially there and helps bring it to fruition. Respect is the art of love by which married couples honorwhat is unique and best in each other.The underlined phrase "→agree to disagree”←in Paragraph 4 means that____.A. one should realize that no two people are the sameB. one should be keen to find out his or her partners meritsC. one should face the reality that his or her partner is not a perfect personD. one should realize that he or she should appreciate differences on the part of his or her partner7.(单项选择题)(每题 2.00 分) Which of the following activities can be used to check students’ understanding of difficult sentences in the text?

Today, unexpected numbers of young adults are living with their parents, "there is a major shift in the middle class," declares sociologist Allan Schnaibergof Northwestern University, whose son, 19, moved back in after an absence of eight months.Analysts cite a variety of reasons for this return to the nest. The marriage age is rising,a condition that makes home and its pleasantness particularly attractive to young people.A high divorce rate and a declining remarriage rate are sending economically pressed and emotionally hurt survivors back to parental shelters. For some, the expense of anaway-from-home college education has become so excessively great that many students now attend local schools. Even after graduation, young people find their wings clipped by skyrocketing housing costs.Living at home, says Knighton, a school teacher, continues to give her security and moral support. Her mother agreed, "Its ridiculous for the kids to pay all that money for rent.It makes sense for kids to stay at home. " But sharing the family home requires adjustmentsfor all. There are the hassles over bathrooms, telephones and privacy. Some families, however, manage the delicate balancing act. But for others, it proves too difficult. Michelle Del Turco,24, has been home three times and left three times. "What I considered a social drink,my dad considered an alcohol problem," she explains. "He never liked anyone I dated, so I either had to hide away or meet them at friends house.Just how long should adult children live with their parents before moving on? Mostpsychologists feel lengthy home comings are a mistake. Children, struggling to establish separate identities, can end up with "a sense of inadequacy, defeat and failure."

What gives unity to the whole Scholastic movement, the academic practice in Europe from the 9th to the 17th centuries, are the common aims, attitudes, and methods, generally accepted by all its members. The chief concern of the Scholastics was not to discover new facts but to integrate the knowledge already acquired separately by Greek reasoning and Christian revelation. This concern is one of the most characteristic differences between Scholasticism and modem thought since the Renaissance. The basic aim of the Scholastics determined certain common attitudes, the most important of which was their conviction of the fundamental harmony between reason and revelation. The Scholastics maintained that because the same God was the source of both types of knowledge and truth was one of his chief attributes, he could not contradict himself in these two ways of speaking. Any apparent opposition between revelation and reason could be traced either to an incorrect use of reason or to an inaccurate interpretation of the words of revelation. Because the Scholastics believed that revelation was the direct teaching of God, it possessed for them a higher degree of truth and certainty than did natural reason. In apparent conflicts between religious faith and philosophic reasoning, faith was thus always the supreme arbiter; the theologian’s decision overruled that of the philosopher. After the early 13th century, Scholastic thought emphasized more the independence of philosophy within its own domain. Nonetheless, throughout the Scholastic period, philosophy was called the servant of theology, not only because the truth of philosophy was subordinated to that of theology, but also because the theologian used philosophy to understand and explain revelation.This attitude of Scholasticism stands in sharp contrast to the so-called double-truth theory of the Spanish-Arab philosopher and physician Averroes. His theory assumed that truth was accsssible to both philosophy and Islamic theology but that only philosophy could attain it perfectly. The so-called truths of theology served, hence, as imperfect imaginative expressions for the common people of the authentic truth accessible only to philosophy. Averroes maintained that philosophic truth could even contradict, at least verbally,the teachings of Islamic theology.As a result of their belief in the harmony between faith and reason, the scholastics attempted to determine the precise scope and competence of each of these faculties. Many early Scholastics,such as the Italian ecclesiastic and philosopher Stanselm, did not clearly distinguish the two and were overconfident that reason could prove certain doctrines of revelation. Later, at the height of the mature period of Scholasticism, the Italian theologian and philosopher St. Thomas Aquinas worked out a balance between reason and revelation. It can be inferred from Paragraph 2 of the text that→ ←.A. the position of philosophy as a humble servant was acceptedB. religion had turned into a hamper to the functioning of philosophyC. philosophers often quoted revelation to support themselvesD. philosophers were sometimes referred to in religious practice27.(单项选择题)(每题 2.00 分) Language is a tool of communication.

Heres one startling fact: By 2030 the projected costs of Social Security and Medicare could easily consume via higher taxes-a third of workers future wage and salary increases. Were mortgaging workers future pay gains for baby boomers retirement benefits.This matters because Social Security and Medicare are pay-as-you-go programs. Current taxpayers pay current benefits. Future taxpayers will pay future benefits. Baby boomers retirement benefits will come mostly from their children and grandchildren, who will be tomorrow’s workers. Consequently, baby boomers children and grandchildren face massive tax increases. Social Security and Medicare spending now equals 14 percent of wage and salary income, reports Elizabeth Bell, a research assistant to Eugene Steuerle of the Urban Institute, Washington, D. C. By 2030, using the trustees various projections, that jumps to 26 percent. Of course, payroll taxes dont cover all the costs of Social Security and Medicare. Still, these figures provide a crude indicator of the economic burden, because costs are imposed heavily on workers via some tax, government borrowing and cuts in other government programs.It can be argued that the costs are bearable. The wage gains in the trustees reports could prove too pessimistic. Like all forecasts, theyre subject to errors. Even if they come true, they assume that tomorrow’s wages will be higher than today’s. Productivity increases; wages rise. In 2030, under the trustees "intermediate" assumptions, workers before tax incomes would be about a third higher than now, says Tom Saving of Texas A&M University. Whats the complaint if workers lost through steeper taxes-some of that? Why shouldnt they generously support parents and grandparents? Well, maybe they will. But there are at least two possible flaws in this logic.The first is that, on a year-to-year basis, wage gains would be tiny-less than 1 percent. When theyve gotten that low before, people have complained that theyre "on a treadmill" and that the American dream has been withdrawn. Even these gains might be diluted by further tax increases to trim today’s already swollen budget deficits. The second and more serious threat is that higher taxes would harm the economy. They might dull economic vitality by reducing investment and the rewards for work and risk-taking. Productivity and wage gains might be smaller than predicted. Then we’d flirt with that death spiral: Wed need still higher taxes to pay benefits, but those taxes might depress economic growth more.One way or another, workers may get fed up with paying so much of their paychecks to supportretirees, many of whom were living quite comfortably. So we ought to redefine the generational compact to lighten the burden of an aging population on workers. The needed steps are clear:to acknowledge longer life expectancies by slowly raising eligibility ages for Social Security and Medicare; to limit future spending by curbing retirement benefits for thebetter-off; to keep people in the productive economy longer by encouraging jobs that mix "work” and "retirement".The main tax base for Social Security and Medicare is→←.A. retirement benefitsB. the wage and salaryC. governments budgetD. trustee fund29.(单项选择题)(每题 2.00 分) When a teacher teaches young learners English pronunciation,he should→ ←.A.

How can we find Love?The past ages of man have all been carefully labeled by anthropologists. Descriptions like "Paleolithic Man", "Neolithic Man", etc., neatly sum up the whole periods. When the timecomes for anthropologists to turn their attention to the twentieth century, they will surely choose the label "Legless Man". Histories of the time will go something like this. "In the twentieth century, people forgot how to use their legs. Men and women moved about in cars, buses and trains from a very early age. There were lifts and escalators in all large buildings to prevent people from walking. This situation was forced upon earth dwellers of that time because of miles each day. But the surprising thing is that they didn't use their legs even when they went on holiday. They built cable railways, ski lifts and roads to the top of every huge mountain. All the beauty spots on earth were marred by the presence of large car parks." The future history books might also record that we were deprived of the use of our eyes. In our hurry to get from one place to another,we failed to see anything on the way. Air travel gives you a bird's eye view of the world-or even less if the wing of the aircraft happens to get in your way. When you travel by car or train a blurred image of the countryside constantly smears the windows. Car drivers, in particular, are forever obsessed with the urge to go on and on: they never want to stop. Is it the lure of the great motorways, or what? And as for sea travel, it hardly deserves mention. It is perfectly summed up in the words of the old song: "I joined the navy to see the world, and what did I see? I saw the sea". The typical twentieth century traveler is the man who always says, "I've been there. " You mention the remotest, most evocative place names in the world like E1 Dorado, Kabul, Irkutsk and someone is bound to say, "I've been there meaning" I drove through it at 100 miles an hour on the way to somewhere else ".When you travel at high speed, the present means nothing; you live mainly in the future because you spend most of your time looking forward to arriving at some other place. But actual arrival, when it is achieved, is meaningless. You want to move on again. By traveling like this, you suspend all experience; the present ceases to be a reality: you might just as well be dead. The traveler on foot, on the other hand, lives constantly in the present. For him traveling and arriving is one and the same thing: he arrives somewhere with every step be makes. He experiences the present moment with his eyes, his ears and the whole of his body. At the end of his journey he feels a delicious physical weariness. He knows that sound satisfying sleep will be just the reward of all true travelers. Traveling at high speed means→←.A. people's focus on the futureB. a pleasureC. satisfying drivers' great thrillD. a necessity of life35.(单项选择题)(每题 2.00 分) Passage TwoThere was a time in my life when beauty meant something special to .me. I guess that would have been when I was about six or seven years old,just several weeks or maybe a month before the orphanage (孤儿院)turned me into an old man.I would get up every morning at the orphanage, make my bed just like the little soldier that I had become and then I would get into one of the two straight lines and march to breakfast with the other twenty or thirty boys who also lived inmy dormitory.After breakfast one Saturday morning I returned to the dormitory and saw the house parent chasing the beautiful monarch butterflies who lived by the hundreds in the bushes scattered around the orphanage.I carefully watched as he caught these beautiful creatures, one after another, and then took them from the net and then stuck straight pins through their head and wings, pinning them onto a heavy cardboard sheet.How cruel it was to kill something of such beauty. I had walked many times out into the bushes, all by myself, just so the butterflies could land on my head, face and hands so I could look at them up close.When the telephone rang the house parent laid the large cardboard paper down on the back cement (水泥) step and went inside to answer the phone. I walked up to the cardboard and looked at the one butterfly who he had just pinned to the large paper. It was still moving about so I reached down and touched it on the wing causing one of the pins to fall out. It started flying around and around trying to get away but it was still pinned by the one wing with the other straight pin. Finally its wing broke off and the butterfly fell to the ground and just trembled.I picked up the tom wing and the butterfly and I spat on its wing and tried to get it to stick back on so it could fly away and be free before the house parent came back. But it would not stay on him. The author set the living butterfly free because______ .A. he liked it very muchB. he had sympathy for the beautiful butterflyC. he couldn't bear a butterfly dying in his favorite bushesD. its wing broke off36.(单项选择题)(每题 2.00 分) The machine looked like a large,old-fashioned→←typewriter.A. forcefulB. clumsyC. intenseD. tricky37.(单项选择题)(每题 2.00 分) → ←is the home of golf.A.

Seven others were so badly damaged that their owners had to leave them, and fifteen others had broken windows or broken roofs. One person was killed, several were badly hurt and taken to hospital, and a number of other people received smaller hurt. Altogether over two hundred people were homeless after the storm.A farmer, Mr.Tan, said that the storm began early in the morning and lasted for over an hour. "I was eating with my wife and children, "he said, "When we heard a loud noise. A few minutes later our house fell down on top of US. We tried our best to climb out but then I saw that one of my children was missing. I went back inside and found him. safe but very frightened."Mr s. Woo Mei Fong said that her husband had just left for work when she felt that her house was moving. She ran outside at once with her children ."There was no time to take anything,"she said, "A few minutes later, the roof came down."Soldiers helped to take people out of the flooded area and the welfare department brought them food, clothes and shelter.Which of the following may be the best title for this passage?→←。

Q. Liu et al.
Jacobian. Let X / S and E / S be the minimal regular models of X K and E K , respectively. Let m denote the order of the element of H 1 ( K , E K ) corresponding to the torsor X K . If T denotes the type of E k , then X k is of type mT . The most difficult part of this theorem is the case of additive reduction. As a corollary to Theorem 6.6 and of results of B´ egueri [5] and Bertapelle [6] on the structure of H 1 ( K , E K ) when K is complete, we prove in 6.7 the existence of torsors X K having reduction of type mT , for any additive type T and integer m = pn and, in case the type T is semi-stable, for any integer m > 0. To prove Theorem 6.6, we first show in 3.8 that there exists a canonical map of O K -modules H 1 ( X , O X ) → H 1 ( E , O E ) which extends the natural isomorphism H 1 ( X K , O X K ) → H 1 ( E K , O E K ). The existence of this map is the main link between X and E , and is proved in the following general theorem on N´ eron models of Jacobians. Theorem 3.1 (Raynaud, unpublished [47]). Assume that k is algebraically closed. Let f : X → S be a proper flat curve, with X regular and with f ∗ O X = O S . Let J/ S denote the N´ eron model of the Jacobian of X K / K , and let Lie ( J ) denote its Lie algebra. Then the canonical morphism of O K -modules H 1 ( X , O X ) → Lie ( J ), which induces the canonical isomorphism H 1 ( X K , O X K ) → Lie ( JK ), has a kernel and cokernel of same length. This theorem is a key ingredient in the proof of Theorem 6.6, and we provide here a complete proof. The statement and proof of Theorem 6.6 in the function field case was also known to Raynaud at the time he wrote [47]. Independently, Cossec and Dolgachev provided a proof of a slightly weaker version of Theorem 6.6 in the function field case in [11], Theorem 5.3.1, also using [47] as one of the main ingredient in their proof. The statement of 6.6 in the function field case is mentioned without proof in the second paragraph of [23]. The proof of Theorem 3.1 relies on Raynaud’s results on Picard functors in [48], and on a theorem on morphisms of group schemes of finite type that is of independent interest: Let u : G → G be a morphism of smooth group schemes of finite type over a complete discrete valuation ring O K with algebraically closed residue field k. Assume that u K : G K → G K is surjective with smooth kernel. Then the length of the cokernel of Lie (u ) : Lie (G ) → Lie (G ) is expressed in 2.1 in terms of two other invariants, the first one obtained using the group smoothening of Ker (u ), and the second one defined as the dimension of a smooth group scheme D/k constructed so that D(k) = Coker (G ( S ) → G ( S )).

a r X i v :q u a n t -p h /0607097v 3 4 J u l 2008A new type of solution of the Schr¨o dinger equation on a self-similar fractal potentialN L Chuprikov and O V SpiridonovaTomsk State Pedagogical University,634041,Tomsk,RussiaAbstract.Scattering a quantum particle by a self-similar fractal potential on a Cantor set is investigated.We present a new type of solution of the functional equation for the transfer matrix of this potential,which was derived earlier from the Schr¨o dinger equation.PACS numbers:03.65.Ca,03.65.XpIn this Letter we address the model[1,2]of scattering a quantum particle by aself-similar fractal potential(SSFP)given on a Cantor set.This scattering problem is,perhaps,the most simple one to allow studying the influence of the scale invariance ofideal deterministic fractals on physical processes in continuous media to involve suchfractal structures.Note that the sharp attenuations,found in[1],in the spectrum of probability wavestransmitted through this ideal fractal potential have also been observed experimentally(see[3])in the transmission spectrum of electromagnetic waves propagating through areal fractal medium(a numerical modelling for the corresponding pre-fractals see in[4]).However,the problem is that the model[1,2]remans incomplete in some respects.Inthis Letter we present a new type of solution to the Schr¨o dinger equation on the SSFP,in addition to two types presented in[1,2].So,let V(x)be a SSFP on the generalized Cantor set in the interval[0,L];eachlevel of the SSFP consists of N(N≥2)SSFPs of the next level whose width isαtimes smaller than that of the former(see[2]).Let also W be a power of the SSFP,that is,its total area:W= ∞−∞V(x)dx.In line with[1,2],for a particle with a given energy E(E=¯h2k2/2m),the transfer matrix Z(φ)(φ=kL)of the SSFP must obeythe functional equationZ(φ)=Z(αφ)[D(γφ)Z(αφ)]N−1;(1)Z(φ)= q(φ)p(φ)p∗(φ)q∗(φ) ,D(φ)= e iφ00e−iφ ;q(φ)=1T(φ)exp[−iJ(φ)],p(φ)= T(φ)exp i πα(N−1);R=1−T;T(φ),J(φ)and F(φ)are,respectively,the transmissioncoefficient and phase characteristics of the SSFP;here F=0for the SSFP-barriers and F=πfor the SSFP-wells(see[2]).As it has turned out,Eq.(1)not uniquely determines the transfer matrix of the SSFP.Two different types of solutions of this equation have been presented in[1,2]. Remind that thefirst type was obtained for any values of W,αand N to characterize the SSFP.In this case,for small values ofφ, 2−J.The second type of solutions exists only for the SSFP-barriers,if W=3N¯h2T(φ)∼y(φ)∼φfor small values ofφ.In this Letter we present a new(third)type of solutions(found by Chuprikov),with a cardinally different behavior of the tunneling parameters in the asymptotic region. Namely,in this case,for small values ofφwe haveT(φ)= 1+cosh2[ω(ln(φ))]sinh2(cφ−s) −1,J(φ)=arctan{sinh[ω(ln(φ))]tanh(cφ−s)},(2)where c is a nonzero constant;ωis a nonzero real-valued function to obey the condition,ω[ln(φ)]=ω[ln(φ)+ln(α)].To extend this solution onto the whole ln(φ)-axis,one has to use the recurrence relations(18)and(19)presented in[2].As in[1,2],we display here ln(R/T)versus ln(φ).Figures(1)-(6)show this function for three values ofω-1,10and15-and three values of c-0.001,0.01and0.1.As is seen,there are three regions on the ln(φ)-axis, with a qualitatively different dependence of ln(R/T):in the left regionln ln(R/T)∼ln(2|c|)−s ln(φ);in the right oneln( R/T¨ˆ)∼−2s ln(φ),where R/T is the envelop of R(φ)/T(φ).As regards the middle region,two qualitatively different types of changing this function are possible here.Forω=1and all three values of c(seefigures(1)and(2)) ln(R/T)∼−2s ln(φ).Such behavior also occurs forω=10and c=0.001(seefigures(3)and(4)).At the same time,forω=15and all three values of c(seefigures(5)and(6)),as well as for ω=10and c=0.1(seefigures(3)and(4))we haveln(R/T)∼−2ln(φ).Note that the right region appears for all three types of solutions(see[2]).As regards the left one to follow from(2),such a behavior is a distinctive feature of the third type of solutions.It is also important to note here that for the solutions of thefirst and third types the phase path of the wave inside the out-of-barrier regions(i.e.,in the regions where the potentials are equal to zero)is infinitesimally small in comparison with the wave path in the barrier regions.This feature distinguishes these types of solutions from the second one.A simple analysis shows that the tunneling parameters are non-differentiable functions at the pointφ=0,whenωdepends onφ.Figure7shows the function R(φ)/T(φ)for this case.So,there are at least three types of the transfer matrices of the SSFP.As is seen, though all of them are nonzero only on the Cantor set,i.e.,the set of zero measure, we deal with different potentials.The Cantor set is a non-countable one,and,thus,it yet provides a much enough room for setting potentials with such different scattering properties.Of course,in this case,it is of great importance is tofind the sequences of pre-fractals to lead to the SSFPs,when the generation number of pre-fractals tends to infinity.Additionally,another open question regarding the model is that the parameters to enter the third type of solutions remain to be connected to the SSFP parameters.References[1]Chuprikov N L2000J.Phys.A:Math.Gen.334293[2]Chuprikov N L and D N Zhabin2000J.Phys.A:Math.Gen.334309[3]Takeda M W,Kirihara S,Miyamoto Y,Sakoda K and Honda K2004Phys.Rev.Lett.92093902[4]Honda K and Otobe Y2006J.Phys.A:Math.Gen.39L315Figure captions\Figure{\label{fig1}The$\ln(\phi)$-dependence of$\ln(R/T)$for$s=0.5$,$c=0.001$ and$\omega=1$;bold full curve-$N=2$,thin full curve-$N=4$;points show the asymptote$13-2s\ln(\phi)$.\Figure{\label{fig2}The$\ln(\phi)$-dependence of$\ln(R/T)$for$N=3$,$\alpha=13$ and$\omega=1$;broken curve-$c=0.1$;thin full curve-$c=0.01$;bold full curve-$c=0.001$;circles show the asymptote$10-2s\ln(\phi)$.\Figure{\label{fig3}The$\ln(\phi)$-dependence of$\ln(R/T)$for$s=0.5$,$c=0.001$ and$\omega=10$;bold full curve-$N=2$,thin full curve-$N=4$;points show the asymptote$3-2s\ln(\phi)$.\Figure{\label{fig4}The$\ln(\phi)$-dependence of$\ln(R/T)$for$N=3$,$\alpha=13$ and$\omega=10$;broken curve-$c=0.1$;thin full curve-$c=0.01$;bold full curve-$c=0.001$;points show the asymptote$8-2\ln(\phi)$;circles show the asymptote$4-2s\ln(\phi)$.\Figure{\label{fig5}The$\ln(\phi)$-dependence of$\ln(R/T)$for$s=0.5$,$c=0.001$ and$\omega=15$;bold full curve-$N=2$,thin full curve-$N=4$;points show the asymptote$5-2\ln(\phi)$.\Figure{\label{fig6}The$\ln(\phi)$-dependence of$\ln(R/T)$for$N=3$,$\alpha=13$ and$\omega=15$;broken curve-$c=0.1$;thin full curve-$c=0.01$;bold full curve-$c=0.001$;points show the asymptote$8-2\ln(\phi)$;circles show the asymptote$4-2s\ln(\phi)$.\Figure{\label{fig7}The$\ln(\phi)$-dependence of$\ln(R/T)$for$s=0.5$,$c=0.001$ and$\omega=15\left[\sin\left(2\pi\frac{\ln(\phi)}{\ln(\alpha)}\right)+1.001\right]$; bold full curve-$N=2$,thin full curve-$N=4$;points show the asymptotes$5-2\ln(\phi)$and$14-2s\ln(\phi)$.。
