Though not biologically related, friends are as "related" as fourth cousins, sharing about 1% of genes. That is 1 a study,published from the University of California and Yale University in the Proceedings of the National Academy of Sciences, has 2 .
The study is a genome-wide analysis conducted 3 1932 unique subjects
which 4 pairs of unrelated friends and unrelated strangers. The same people were used in both 5 .
While 1% may seem 6 , it is not so to a geneticist. As co-author of the study James Fowler, professor of medical genetics at UC San Diego, says, "Most people do not even 7 their fourth cousins but somehow manage to select as friends the people who 8 our kin."
The study 9 found that the genes for smell were something shared in friends but not genes for immunity. Why this similarity exists in smell genes is difficult to explain, for now. 10 , as the team suggests, it draws us to similar environments but there is more 11 it. There could be many mechanisms working
together that 12 us in choosing genetically similar friends 13 "functional kinship" of being friends with 14 !
One of the remarkable findings of the study was that the similar genes seem to be evolving 15 than other genes. Studying this could help 16 why human evolution picked pace in the last 30,000 years, with social environment being a
major 17 factor.
The findings do not simply explain people's 18 to befriend those of
similar 19 backgrounds, say the researchers. Though all the subjects were drawn from a population of European extraction, care was taken to 20 that all subjects, friends and strangers were taken from the same population.
1. [A] when [B] why [C] how [D] what
【答案】[D] what
【解析】该题考查的是语法知识。根据句子结构和选项的特点，可以判断出空格处应填从属连词引导从句;再根据句子的内容，可以看出该从句是一项研究的相关内容(what)，不是指研究的时间(when)，原因(why)和方式(how)，因此，该题的答案为what。
2. [A] defended [B] concluded [C] withdrawn [D] advised
【答案】[B] concluded
【解析】从此题所在的句子的前后内容可以判断出，that is_______ 中的that是指第一句话的内容(朋友与我们基因上的相关性)，很显然是研究得出的结论。因此，答案为concluded。
3. [A] for [B] with [C] on [D] by
【答案】[C] on
【解析】根据空格所在句子的内容(研究对1932分独特的受试者进行分析)判断出进行分析的对象是1932 unique subjects。conduct analysis on…是固定表达。
4. [A] compared [B] sought [C] separated [D] connected
【答案】[A] compared
【解析】该空格所在的句子是which 引导的定语从句修饰study,意思是：对几对基因不相关的朋友和陌生人进行_______。因为“研究”的内容是关于朋友间基因上的相关性问题，所以完整的意思应该是：对几对基因不相关的朋友和陌生人进行比较。所以最佳答案为compared。
5. [A] tests [B] objects [C]samples [D] examples
【答案】[C] samples
【解析】根据空格的前后内容判断，到第五个空为止，文章都在讲实验过程，和实验对象，第五个空格所在句子的内容是：相同的人们都用于实验中的这两类______。所以根据上下文语境和内容，应该选与实验对象相对应的samples(样例).因此，答案是samples。
6. [A] insignificant [B] unexpected [C]unbelievable [D] incredible
【答案】[A] insignificant
【解析】空的语境为：尽管这1%看起来似乎____，但是遗传学家可不这么认为。空前后形成对比转折的逻辑关系，而从后文列举的例子中可知遗传学家James Fowler对这1%基因的态度是肯定的，故答案为A。
7. [A] visit [B] miss [C] seek [D] know
【答案】[D] know
【解析】空的语境为：大多数人甚至不____他们隔三代的表亲，但却设法选择那些____我们亲戚的人作为朋友。填入的词必须满足前后句之间的转折逻辑关系，四个选项带入，只有D 选项符合上下文语义。
8. [A] resemble [B] influence [C] favor [D] surpass
【答案】[A] resemble
【解析】空的语境为：大多数人甚至不认识他们隔三代的表亲，但却设法选择那些____我们亲戚的人作为朋友。根据全文中心：基因上的相似性，可知本题选择A。
9. [A] again [B] also [C] instead [D] thus
【答案】[B] also
【解析】空所在的句子开头用“The study…”,显然这是对上文话题的继续阐述，前文指出研究发现朋友与我们有1%的基因关系，而空所在句“the genes for smell were something shared in friends”在进一步详细讨论该话题，前后之间是顺接关系，故答案为B。
10. [A] Meanwhile [B] Furthermore [C] Likewise [D] Perhaps
【答案】[D] Perhaps
【解析】从选项和文字中句子结构可以判断，空格处要求填入一个能够体现前后两个句子逻辑关系的副词，空前的句子谈到“为什么在嗅觉基因方面存在相似性还很难解释”，空后却紧接着对此得出一个相关结论，很明显是矛盾的，所以此结论只能是一种不确定的推测，故答案为D。
11. [A] about [B] to [C]from [D]like
【答案】[B] to
【解析】该题为介词选择题。后半句出现比较级，可见是和前文形成比较关系，因此和上半句介词保持一致，用介词to。该句翻译：它(这种相似性)吸引我们到相同的环境，并且使我们更为相似。因此答案为to。
12. [A] drive [B] observe [C] confuse [D]limit
【答案】[A] drive
【解析】该句意思为：很多机制共同作用，从而_____我们选择基因相似的朋友，_____和_____交朋友的“功能关系”。根据上下文可知，此处所填入动词需符合结构_____sb. in doing sth，B选项observe(观察，遵守)和C选项confuse(困惑)均无此用法。符合该结构只有A选项drive(驱使)和D选项limit(限制)。根据上下文可得知：这些机制驱使我们选择基因相似的朋友，符合文章主题。如果选限制则为反向干扰。因此答案为drive。
13. [A] according to [B] rather than [C] regardless of [D] along with
【答案】[B] rather than
【解析】所填词为逻辑关系短语，空前说选择基因相似的朋友，空后说具有“实用关系”的朋友，可知前后为对立关系，并且根据文章主题，可知肯定前者而否定后者，可锁定B选项rather than。A选项according to(根据)没有体现出对立及取舍关系，因此排除;C选项regardless of(不管)表让步关系，干扰性较强，但文章更强调取前舍后，因此排除;D选项along with(伴随)表顺接，故排除。故答案为rather than。
14. [A] chances [B]responses [C]missions [D]benefits
【答案】[D] benefits
【解析】根据前文functional kinship(实用关系)可得出D选项benefits(利益)，前后形成呼应。A选项chances(机会)、B选项responses(反应)、C选项missions(使命)均不符合题意。故答案为benefits。
15. [A] later [B]slower [C] faster [D] earlier
【答案】[C] faster
【解析】该句为：evolving ______ than other genes(比其他基因进化得______). 根据同词复现，我们找到该段第二句话中：human evolution picked pace in the last 30,000 years(人类进化在过去30000年间提速)。C 选项faster与下文picked pace(加速)形成呼应，故答案为faster。
16. [A]forecast [B]remember [C]understand [D]express
【答案】[C] understand
【解析】此题考查动词。根据语意。空格后面是一个why引导的宾语从句，意为“人类进化在过去三万年间得以加速的原因”，表示这一研究的结果和意义。能与这一宾语从句构成搭配的只有C选项understand。A选项forecast“预测”与“过去三万年”相矛盾，B选项remember“记住”和D选项“express”均不符合文意。
17. [A] unpredictable [B]contributory [C] controllable [D] disruptive
【答案】[B] contributory
【解析】此空需要填入一个形容词，表达社会环境对人类进步所起到的作用。help，pick pace 这两个词表达的都是积极的含义，因此此处需要填入一个带有褒义的感情色彩的词，因此排除A选项“不可预测的”和D选项“破坏性的”; B 而C选项“可控的”,与语意无关;因此正确答案为B选项contributory“促进的”。
18. [A] endeavor [B]decision [C]arrangement [D] tendency
【答案】[D] tendency
【解析】此处进一步陈述这一研究的结论。A选项endeavor“努力”，B选项“决定”，C 选项“安排”，D选项“倾向”。本文的主旨重在解释人们在交朋友的不自觉的一种倾向，而非通过人为的有意识的举动来选择朋友。因此正确答案为D。
19. [A] political [B] religious [C] ethnic [D] economic
【答案】[C] ethnic
【解析】结合文意，人们普遍希望和有相似基因背景的人。C选项ethnic意为“种族的，民族的”，是对上文中多次重复出现的genes,以及下文的the same population的同义复
现。因此正确答案为C。 A选项political“政治的”， B选项“宗教的”，D选项“经济的”均不符合原文文意。
20. [A] see [B] show [C] prove [D] tell
【答案】[A] see
【解析】此处考察动词，动词势必要看前后搭配。see that 构成固定词组，意为“务必使……”，符合文意，即：即使所有的受访者都拥有欧洲血统，(研究者们)仍然悉心确保所有的受访者、朋友和陌生人都来自于同一群种。选项B“展示”,选项C“证明”，选项D“辨别”均无此含义，且不符合文意。
Section II Reading Comprehension
Part A
Directions:
Read the following four texts. Answer the questions below each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET. (40 points)
Text 1
King Juan Carlos of Spain once insisted “kings don’t 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 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 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 absolutist counterparts in the Gulf and Asia, most royal families have survived because they allow voters to avoid the difficult search for a non-controversial but respected public figure.
Even so, kings and queens undoubtedly have a downside. Symbolic of national unity as they claim to be, their very history—and sometimes the way they behave today – embodies outdated and indefensible privileges and inequalities. At a time when Thomas Piketty and other economists are 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 states.
The most successful monarchies strive to abandon or hide their old aristocratic ways. Princes and princesses have day-jobs and ride bicycles, not horses (or helicopters). Even so, these are wealthy families who party with the international 1%, and media intrusiveness makes it increasingly difficult to maintain the right image.
While Europe’s 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 monarchy’s reputation with her rather ordinary (if well-heeled) granny style. The danger will come with Charles, who has both an expensive taste of lifestyle and a pretty hierarchical view of the world. He has failed to understand that monarchies have largely survived because they provide a service – as non-controversial and non-political heads of state. Charles ought to know that as English history shows, it is kings, not republicans, who are the monarchy’s 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 royals
[C] cased his relationship with his rivals
[D]ended his reign in embarrassment
【答案】[D] ended his reign in embarrassment
【解析】事实细节题。根据题干要求，定位到文章前两段。而文章第一段的第二句话提到“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.”(在最近的欧洲选
“stand 举中，令人尴尬的丑闻和受欢迎的共和党，均迫使Carlos收回前言并退位)。D选项中，
down”是“end reign”的同义置换，且“embarrassment”与导致Carlos卸任的原因“embarrassing scandals”是相呼应的。故D是正确答案。A、B、C均属于无中生有。
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
[D]due to their everlasting political embodiment
【答案】[A] owing to their undoubted and respectable status
【解析】事实细节题。根据题干关键词“monarchs”和“heads of state”，定位到第三段的最后一句话“...most royal families have survived because they allow voters to avoid the difficult search for a non-controversial but respected public figure.”(大多数的王室幸存下来是由于他们让选民可以避免去寻找一个不受争议且受尊敬的公众人物的困难)其中“non-controversial but respected public figure”正是A选项中“undoubted and respectable status”的同义置换。故A是正确答案。
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
[D]The nobility’s adherence to their privileges
【答案】[B] The role of the nobility in modern democracies
【解析】事实细节题。定位在第四段的最后一句话“...it is bizarre that wealthy aristocratic families should still be the symbolic heart of modern democratic states.”(离奇的是，富有的贵族竟然仍是现代民主国家的象征核心)其中，the symbolic heart of modern democratic states是题干the role of the nobility in modern democracies的同义置换。
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
【答案】[D] fails to adapt himself to his future role
【解析】事实细节题。该题考查：英国皇家贵族们非常害怕是因为查尔斯……。根据题干专有名词Charles可定位到文章第七段“the danger will come with Charles...worst enemies”。本段指出“危险源自于查尔斯，他生活奢靡，等级观念显著;并且他没有意识到君王的幸存很大程度上取决于君王提供了公共服务，同时，查尔斯并不知道，国王才是君主制度最大的敌人，而非共和党人。”选项A意为：对待政治问题态度强硬，文章并无提及;选项B意为，对待建议的生活方式改变失败，文章中提到生活方式，但并未提到改变生活方
式;选项C意为：视共和党人为潜在盟友，文章中提到，共和党人并非最大的敌人，并未指明把共和党人视为盟友，属于偷换概念，选项D意为：适应未来身份失败，文章指出查尔斯的生活方式，世界观以及他对于君王制度的错误理解均为身份特殊的他的不正确言行，与选项D表述吻合，故为正确答案。
25. Which of the following is the best title of the text?
[A] Carlos, Glory and Disgrace Combined
[B] Charles, Anxious to Succeed to the Throne
[C] Carlos, a Lesson for All European Monarchs
[D]Charles, Slow to React to the Coming Threats
【答案】[C] Carlos, a Lesson for All European Monarchs
【解析】主旨大意题。该题考察四个选项中哪个可作为文章最佳标题。文章从西班牙国王Carlos退位事件切入，主要讨论当下欧洲君王制度所存在的问题，并非讨论查尔斯的事件，即可排除选项B“查尔斯—继位焦虑”和D“查尔斯—应对威胁缓慢”，而选项A“卡洛斯—荣辱并存”和C“卡洛斯—欧洲君王们的前车之鉴”中，选项A属于细节信息，不能概括文章大意，选项C可概括，故为正确答案。另外，文章主题词Monarch只有在选项C中出现，也可作为迅速解题的依据。

Just 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 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 implications of new and rapidly changing technologies. The court would be recklessly modest if it followed California’s 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 discarding California’s lame argument that exploring the contents of a smart phone — a vast storehouse of digital information — is similar to, say, rifling through a suspect’s purse. The court has ruled that police don’t violate the Fourth Amendment when they sift through the wallet or pocketbook of an arrestee without a warrant. But exploring one’s smart phone is more like entering his or her home. A smart phone may contain an arrestee’s reading history, financial history, medical history and comprehensive records of recent correspondence. 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 expect private documents to remain private and protected by the Constitution’s prohibition on unreasonable searches.
As so often is the case, stating that principle doesn’t 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 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 not swallow California’s argument whole. New, disruptive technology sometimes demands novel applications of the Constitution’s 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 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 Supreme 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.
[D]prohibit suspects from using their mobile phones.
【答案】[C] check suspects’ phone contents without being authorized
【解析】这是一道事实细节题，根据题干关键词The Supreme Court回文定位到第一段的第二句话，“The Supreme Court will now consider whether police can search for the contents of a mobile phone without a warrant if the phone is on or around a person during an arrest”,一一比对选项，原文中的“police can search for the contents of a mobile phone without a warrant”与选项C “check suspects’ phone contents without being authorized”是同义替换，其他选项均是无关选项。
27. The author’s attitude toward California’s argument is one of
[A] disapproval.
[B] indifference.
[C] tolerance.
[D]cautiousness.
【答案】[A] disapproval
【解析】本题是观点态度题，考察作者的态度。根据题干关键词“California’s argument”，可以定位到文章第四段第一句“They should start by discarding California’s lame argument…”。由第四段第一句话中的“discard(抛弃)”和“lame(没有说服力的)”可以看出作者对于California’s argument 是不支持的态度，因此选A。
28. The author believes that exploring one’s phone contents is comparable to
[A] getting into one’s residence.
[B] handling one’s historical records.
[C] scanning one’s correspondences.
[D] going through one’s wallet.
【答案】[A] getting into one’s residence
【解析】根据题干关键词the author believes和“exploring one’s phone contents is comparable to”可回文定位到文章第四段第三句“But exploring one’s smartphone is more like entering his or her home”，选项A语义与之一致，其中，getting into与entering 对应，one’s residence与his or her home对应，故A选项为正确答案。
29. The author believes that exploring one’s phone contents is comparable to
[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.
【答案】[C] citizens’ privacy is not effectively protected
【解析】根据题干信息In paragraphs 5and 6定位第5段第一句话“Americans should take steps to protect their digital privacy.及第6段最后一句话，...and they could take reasonable measures to.....，可推知作者的顾虑，因此答案为C.
30. Orin Kerr’s comparison is quoted to indicate that
[A] the Constitution should be implemented flexibly.
[B] new technology requires reinterpretation of the Constitution.
[C]California’s argument violates principles of the Constitution.
[D]principles of the Constitution should never be altered
【答案】[A] the Constitution should be implemented flexibly
【解析】这是一道例证题，根据题干关键词Orin Kerr可以回文定位到文章最后一段。作者引用Orin Kerr这个人的比较是为了说明相关的论点。分析最后一段结构可知，最后一段的第三句和第四句都是在阐述该例子本身，所以相关论点应该往前面找，即是第二句话，“New，disruptive technology sometimes demands novel applications of the Constitution’s protection”,选项A与之同义替换，其中，be implemented和applications对应，novel 和flexibly对应。

The journal Science is adding an 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 findings.
“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 additional scrutiny by the journal’s 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 ‘statistics board’ was motivated by concerns broadly with the application of statistics and data analysis in scientific research and is part of Science’s 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 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 Science 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 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 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 in 2012, but journals should also take a tougher line, “engaging reviewers who are statistically literate and editors who can verify the process”. Vaux says that Science’s 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 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 common in research projects.
【答案】[B] journals are strengthening their statistical checks
【解析】推理题。根据题干直接定位到第一段。解题关键在于第二句The policy follows similar efforts from other journals(该政策得到其他期刊类似的努力)the policy指第一句The journal Science is adding an extra round of statistical checks to its
