(40 points)Text 1King Juan Carlos of Spain once insisted “kings dont abdicate, they dare in their sleep.” But

11、embarrassing scandals and the popularity of the republican 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 magni

12、ficent uniforms and majestic lifestyle?The Spanish case provides arguments both for and against monarchy. When public opinion is particularly polarised, as it was following the end of the Franco regime, monarchs can rise above “mere” politics and “embody” a spirit of national unity.It is this appare

13、nt transcendence of politics that explains monarchs continuing popularity polarized. And also, the Middle East excepted, 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, m

14、ost 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. Symbolic of national unity as they claim to be, their very historyand sometimes the way they behave toda

15、y embodies outdated and indefensible privileges and inequalities. At a time when Thomas Piketty and other economists are warning 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

16、 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 di

17、fficult 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-heele

18、d) 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 to understand that monarchies have largely survived because they provide a service as non-controversial and non-political heads of state. Charle

19、s 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 Paragraphs, King Juan Carlos of SpainA used turn enjoy high public supportB was unpopular among European royalsC cased his relationship with his rivalsDende

20、d his reign in embarrassment22. Monarchs are kept as heads of state in Europe mostlyA owing to their undoubted and respectable statusB to achieve a balance between tradition and realityC to give voter more public figures to look up toDdue to their everlasting political embodiment23. Which of the fol

21、lowing is shown to be odd, according to Paragraph 4?A Aristocrats excessive reliance on inherited wealthB The role of the nobility in modern democraciesC The simple lifestyle of the aristocratic familiesDThe nobilitys adherence to their privileges24. The British royals “have most to fear” because Ch

22、arlesA takes a rough line on political issuesB fails to change his lifestyle as advisedC takes republicans as his potential alliesD fails to adapt himself to his future role25. Which of the following is the best title of the text?A Carlos, Glory and Disgrace CombinedB Charles, Anxious to Succeed to

23、the ThroneC Carlos, a Lesson for All European MonarchsDCharles, Slow to React to the Coming ThreatsText 2Just how much does the Constitution protect your digital data? The Supreme Court will now consider whether police can search the contents of a mobile phone without a warrant if the phone is on or

24、 around a person during an arrest.California has asked the justices to refrain from a sweeping ruling particularly one that upsets the old assumption that authorities may search through the possessions of suspects at the time of their arrest. It is hard, the state argues, for judges to assess the im

25、plications of new and rapidly changing technologies.The court would be recklessly modest if it followed Californias advice. Enough of the implications are discernable, even obvious, so that the justices can and should provide updated guidelines to police, lawyers and defendants.They should start by

26、discarding Californias lame argument that exploring the contents of a smart phone a vast storehouse of digital information is similar to, say, rifling through a suspects purse. The court has ruled that police dont violate the Fourth Amendment when they sift through the wallet or pocketbook of an arr

27、estee without a warrant. But exploring ones smart phone is more like entering his or her home. A smart phone may contain an arrestees reading history, financial history, medical history and comprehensive records of recent correspondence. The development of “cloud computing,” meanwhile, has made that

28、 exploration so much the easier.Americans should take steps to protect their digital privacy. But keeping sensitive information on these devices is increasingly a requirement of normal life. Citizens still have a right to expect private documents to remain private and protected by the Constitutions

29、prohibition on unreasonable searches.As so often is the case, stating that principle doesnt ease the challenge of line-drawing. In many cases, it would not be overly onerous for authorities to obtain a warrant to search through phone contents. They could still invalidate Fourth Amendment protections

30、 when facing severe, urgent circumstances, and they could take reasonable measures to ensure that phone data are not erased or altered while a warrant is pending. The court, though, may want to allow room for police to cite situations where they are entitled to more freedom.But the justices should n

31、ot swallow Californias argument whole. New, disruptive technology sometimes demands novel applications of the Constitutions protections. Orin Kerr, a law professor, compares the explosion and accessibility of digital information in the 21st century with the establishment of automobile use as a virtu

32、al necessity of life in the 20th: The justices had to specify novel rules for the new personal domain of the passenger car then; they must sort out how the Fourth Amendment applies to digital information now.26. The Supreme Court will work out whether, during an arrest, it is legitimate toA prevent

33、suspects from deleting their phone contents.B search for suspects mobile phones without a warrant.C check suspects phone contents without being authorized.Dprohibit suspects from using their mobile phones.27. The authors attitude toward Californias argument is one ofA disapproval.B indifference.C to

34、lerance.Dcautiousness.28. The author believes that exploring ones phone contents is comparable toA getting into ones residence.B handling ones historical records.C scanning ones correspondences.D going through ones wallet.29. In Paragraph 5 and 6, the author shows his concern thatA principles are ha

35、rd to be clearly expressed.B the court is giving police less room for action.C citizens privacy is not effectively protected.D phones are used to store sensitive information.30. Orin Kerrs comparison is quoted to indicate thatA the Constitution should be implemented flexibly.B new technology require

36、s reinterpretation of the Constitution.CCalifornias argument violates principles of the Constitution.Dprinciples of the Constitution should never be alteredText 3The journal Science is adding an extra round of statistical checks to its peer-review process, editor-in-chief Marcia McNutt announced tod

37、ay. The policy follows similar efforts from other journals, after widespread concern that basic mistakes in data analysis are contributing to the irreproducibility of many published research findings.“Readers must have confidence in the conclusions published in our journal,” writes McNutt in an edit

38、orial. Working with the American Statistical Association, the journal has appointed seven experts to a statistics board of reviewing editors(SBoRE). Manuscript will be flagged up for additional scrutiny by the journals internal editors, or by its existing Board of Reviewing Editors or by outside pee

39、r reviewers. The SBoRE panel will then find external statisticians to review these manuscripts.Asked whether any particular papers had impelled the change, McNutt said: “The creation of the statistics board was motivated by concerns broadly with the application of statistics and data analysis in sci

40、entific research and is part of Sciences overall drive to increase reproducibility in the research we publish.”Giovanni Parmigiani, a biostatistician at the Harvard School of Public Health, a member of the SBoRE group. He says he expects the board to “play primarily an advisory role.” He agreed to j

41、oin because he “found the foresight behind the establishment of the SBoRE to be novel, unique and likely to have a lasting impact. This impact will not only be through the publications in Science itself, but hopefully through a larger group of publishing places that may want to model their approach

42、after Science.”John Ioannidis, a physician who studies research methodology, says that the policy is “a most welcome step forward” and “long overdue.” “Most journals are weak in statistical review, and this damages the quality of what they publish. I think that, for the majority of scientific papers

43、 nowadays, statistical review is more essential than expert review,” he says. But he noted that biomedical journals such as Annals of Internal Medicine, the Journal of the American Medical Association and The Lancet pay strong attention to statistical review.Professional scientists are expected to k

44、now how to analyze data, but statistical errors are alarmingly common in published research, according to David Vaux, a cell biologist. Researchers should improve their standards, he wrote in 2012, but journals should also take a tougher line, “engaging reviewers who are statistically literate and e

45、ditors who can verify the process”. Vaux says that Sciences idea to pass some papers to statisticians “has some merit, but a weakness is that it relies on the board of reviewing editors to identify the papers that need scrutiny in the first place”.31. It can be learned from Paragraph 1 thatA Science

46、 intends to simplify their peer-review process.B journals are strengthening their statistical checks.C few journals are blamed for mistakes in data analysis.D lack of data analysis is common in research projects.32. The phrase “flagged up” (Para. 2) is the closest in meaning toA found.B marked.C rev

47、ised.D stored.33. Giovanni Parmigiani believes that the establishment of the SBoRE mayA pose a threat to all its peers.B meet with strong opposition.C increase Sciences circulation.Dset an example for other journals.34. David Vaux holds that what Science is doing nowA adds to researchers workload.B diminishes the role of reviewers.C has room for further improvemen
