Mark your answers on ANSWER SHEET. (40 points) Text 1 King Juan Carlos of Spain once insisted “kings dont
11、abdicate, they dare in their sleep.” But 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
12、for all European royals, with their magnificent 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
13、spirit of national unity. It is this apparent 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 abso
14、lutist 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. Symbolic of national unity as they claim to be, their very h
15、istoryand sometimes the way they behave today embodies outdated and indefensible privileges and inequalities.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 stil
16、l 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
17、 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 rep
18、utation 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 to understand that monarchies have largely survived because they provide a service as non-controv
19、ersial 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 Paragraphs, King Juan Carlos of Spain A used turn enjoy high public support B was unpopular among European r
20、oyals C cased his relationship with his rivals Dended his reign in embarrassment 22. Monarchs are kept as heads of state in Europe mostly A owing to their undoubted and respectable status B to achieve a balance between tradition and reality C to give voter more public figures to look up to Ddue to t
21、heir everlasting political embodiment 23. Which of the following is shown to be odd, according to Paragraph 4? A Aristocrats excessive reliance on inherited wealth B The role of the nobility in modern democracies C The simple lifestyle of the aristocratic families DThe nobilitys adherence to their p
22、rivileges 24. The British royals “have most to fear” because Charles A takes a rough 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. Which of the following is the best title of the text? A
23、 Carlos, Glory and Disgrace Combined B Charles, Anxious to Succeed to the Throne C Carlos, a Lesson for All European Monarchs DCharles, Slow to React to the Coming Threats Text 2 Just how much does the Constitution protect your digital data? The Supreme Court will now consider whether police can sea
24、rch the contents of a mobile phone without a warrant if the phone is on or 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
25、 of their arrest. It is hard, the state argues, for judges to assess the implications 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 provid
26、e updated guidelines to police, lawyers and defendants. They should start by 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 t
27、he Fourth Amendment when they sift through the wallet or pocketbook of an arrestee 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 c
28、orrespondence. The development of “cloud computing,” meanwhile, has made that 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
29、expect private documents to remain private and protected by the Constitutions 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 t
30、hrough phone contents. They could still invalidate Fourth Amendment protections 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 ci
31、te situations where they are entitled to more freedom. But the justices should not 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 inf
32、ormation in the 21st century with the establishment of automobile use as a virtual 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 Sup
33、reme Court will work out whether, during an arrest, it is legitimate to A prevent 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 a
34、uthors attitude toward Californias argument is one of A disapproval. B indifference. C tolerance. Dcautiousness. 28. The author believes that exploring ones phone contents is comparable to A getting into ones residence. B handling ones historical records. C scanning ones correspondences. D going thr
35、ough ones wallet. 29. In Paragraph 5 and 6, the author shows his concern that A principles are hard 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
36、 is quoted to indicate that A the Constitution should be implemented flexibly. B new technology requires reinterpretation of the Constitution. CCalifornias argument violates principles of the Constitution. Dprinciples of the Constitution should never be altered Text 3 The journal Science is adding a
37、n extra round of statistical checks to its peer-review process, editor-in-chief Marcia McNutt announced today. 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 fi
38、ndings. “Readers must have confidence in the conclusions published in our journal,” writes McNutt in an editorial. 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 additiona
39、l scrutiny by the journals internal editors, or by its existing Board of Reviewing Editors or by outside peer 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 s
40、tatistics board was motivated by concerns broadly with the application of statistics and data analysis in scientific 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,
41、a member of the SBoRE group. He says he expects the board to “play primarily an advisory role.” He agreed to join 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 Sc
42、ience itself, but hopefully through a larger group of publishing places that may want to model their approach 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
43、 review, and this damages the quality of what they publish. I think that, for the majority of scientific papers 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
44、Association and The Lancet pay strong attention to statistical review. Professional scientists are expected to know 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
45、 in 2020, but journals should also take a tougher line, “engaging reviewers who are statistically literate and editors 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
46、 identify the papers that need scrutiny in the first place”. 31. It can be learned from Paragraph 1 that A Science 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
47、 common in research projects. 32. The phrase “flagged up” (Para. 2) is the closest in meaning to A found. B marked. C revised. D stored. 33. Giovanni Parmigiani believes that the establishment of the SBoRE may A pose a threat to all its peers. B meet with strong opposition. C increase Sciences circu
48、lation. Dset an example for other journals. 34. David Vaux holds that what Science is doing now A adds to researchers workload. B diminishes the role of reviewers. C has room for further improvement. Dis to fail in the foreseeable future 35. Which of the following is the best title of the text? A Science Joins Pu
