In 1968, the Congress of the United States passed the Jury Selection and Service Act, ushering in a new era of democratic reforms for the jury. This law abolished special educational requirements for federal jurors and required them to be selected at random from a cross section of the entire community. In the landmark 1975 decision Taylor v. Louisiana, the Supreme Court extended the requirement that juries be representative of all parts of the community to the state level. The Taylor decision also declared sex discrimination in jury selection to be unconstitutional and ordered states to use the same procedures for selecting male and female jurors。

　　36. From the principles of the US jury system, we learn that ______

　　[A]both literate and illiterate people can serve on juries

　　[B]defendants are immune from trial by their peers

　　[C]no age limit should be imposed for jury service

　　[D]judgment should consider the opinion of the public

　　选【D】，因为第一段who meet minimal qualifications of age and literacy，即只要达到基本年龄和文化要求即可，而A选项没有强调最低文化要求，C没有强调最低年龄要求，所以均错。另外，文中只说有权让自己的同伴审讯自己，而B选项说辩护人或被告不会受到同伴的审讯，这个说法于文章不一致，属于无中生有。

　　37. The practice of selecting so—called elite jurors prior to 1968 showed_____

　　[A]the inadequacy of antidiscrimination laws

　　[B]the prevalent discrimination against certain races

　　[C]the conflicting ideals in jury selection procedures

　　[D]the arrogance common among the Supreme Court judges。

　　选【C】，根据第二段段首段尾句，不难看出事与愿违，实际操作与想象不一样，有冲突。B错的原因是偷换了宾语，文章第二段第二句话没有强调当时歧视races(不同种族的人)

　　38. Even in the 1960s, women were seldom on the jury list in some states because_____

　　[A]they were automatically banned by state laws

　　[B]they fell far short of the required qualifications

　　[C]they were supposed to perform domestic duties

　　[D]they tended to evade public engagement

　　选【C】，关键词1960s定位于第三段，A错误的原因不是state law禁止的，BD无中生有。C来自于段尾句the claim that women were needed at home。

　　39. After the Jury Selection and Service Act was passed.___

　　[A]sex discrimination in jury selection was unconstitutional and had to be abolished

　　[B]educational requirements became less rigid in the selection of federal jurors

　　[C]jurors at the state level ought to be representative of the entire community

　　[D]states ought to conform to the federal court in reforming the jury system

　　选【B】，根据第四段第一二两句话，B是正确的。但D错误的原因是，偷换了conform的宾语，应该是根据Jury Selection and Service Act进行改革。AC错误是定位错误，本题于1975年decision Taylor v. Louisiana一事无关。

　　40. In discussing the US jury system, the text centers on_______

　　[A]its nature and problems

　　[B]its characteristics and tradition

　　[C]its problems and their solutions

　　[D]its tradition and development

　　选【C】，从第二段第一句：But as recently as in 1986, jury selection procedures conflicted with these democratic ideals.  第三段第一句：The system also failed to regularly include women on juries until the mid-20th century.  以及第四段第一句In 1968, the Congress of the United States passed the Jury Selection and Service Act, ushering in a new era of democratic reforms for the jury. 不难看出本文从第二段一直到最后，都是在阐述陪审团制度的问题，以及如何解决陪审团制度的问题。

　　原文标题：Copying birds may save aircraft fuel

　　BOTH Boeing and Airbus have trumpeted the efficiency of their newest aircraft, the 787 and A350 respectively. Their clever designs and lightweight composites certainly make a difference. But a group of researchers at Stanford University, led by Ilan Kroo, has suggested that airlines could take a more naturalistic approach to cutting jet-fuel use, and it would not require them to buy new aircraft。

　　第41题：【F】 因为飞机的飞行路线可以改用更具仿生效应的路径来节省燃油，而且并不需要购买新的飞机。

　　The answer, says Dr Kroo, lies with birds. Since 1914, and a seminal paper by a German researcher called Carl Wieselsberger, scientists have known that birds flying in formation—a V-shape, echelon or otherwise—expend less energy. The air flowing over a bird’s wings curls upwards behind the wingtips, a phenomenon known as upwash. Other birds flying in the upwash experience reduced drag, and spend less energy propelling themselves. Peter Lissaman, an aeronautics expert who was formerly at Caltech and the University of Southern California, has suggested that a formation of 25 birds might enjoy a range increase of 71%。

　　第42题：【T】，因为drag有阻力的意思。

　　When applied to aircraft, the principles are not substantially different. Dr Kroo and his team modeled what would happen if three passenger jets departing from Los Angeles, San Francisco and Las Vegas were to rendezvous over Utah, assume an inverted V-formation, occasionally swap places so all could have a turn in the most favorable positions, and proceed to London. They found that the aircraft consumed as much as 15% less fuel (coupled with a reduction in carbon-dioxide output). Nitrogen-oxide emissions during the cruising portions of the flight fell by around a quarter。

　　There are, of course, kinks to be worked out. One consideration is safety, or at least the perception of it. Would passengers feel comfortable traveling in convoy? Dr Kroo points out that the aircraft could be separated by several nautical miles, and would not be in the intimate groupings favored by display teams like the Red Arrows. A passenger peering out of the window might not even see the other planes. Whether the separation distances involved would satisfy air-traffic-control regulations is another matter, although a working group at the International Civil Aviation Organization has included the possibility of formation flying in a blueprint for new operational guidelines。

　　第43题：【T】，根据以上划线部分，即飞机间会相隔几海里，不会像红箭表演队(英国皇家空军特技表演队)那样间距小到令人窒息。乘客往窗外看也许都看不到另外的飞机。可以得出乘客其实不受影响。另外要注意的是，题目中的more在这里不表示比较级。

　　It remains to be seen how weather conditions affect the air flows that make formation flight more efficient. In zones of increased turbulence, the planes’ wakes will decay more quickly and the effect will diminish. Dr Kroo says this is one of the areas his team will investigate further. It might also be hard for airlines to co-ordinate the departure times and destinations of passenger aircraft in a way that would allow them to gain from formation flight. Cargo aircraft, in contrast, might be easier to reschedule, as might routine military flights。

　　第44题：【T】段首句强调“天气情况对气流的影响现在仍需观察”所以本题正确。

　　As it happens, America’s armed forces are on the case already. Earlier this year the country’s Defense Advanced Research Projects Agency announced plans to pay Boeing to investigate formation flight, though the program has yet to begin. There are reports that some military aircraft flew in formation when they were low on fuel during the Second World War, but Dr Lissaman says they are apocryphal. “My father was an RAF pilot and my cousin the skipper of a Lancaster lost over Berlin,” he adds. So he should know。

　　第45题：【F】根据but转折词，即划线部分，但Dr Lissaman称那些都是杜撰的。

　　41. Findings of the Stanford University researchers will promote the sales of new Boeing and Airbus aircraft。

　　42. The upwash experience may save propelling energy as well as reducing resistance。

　　43. Formation flight is more comfortable because passengers can not see the other planes。

　　44. The role that weather plays in formation flight has not yet been clearly defined。

　　45. It has been documented that during World War II, America’s armed forces once tried formation flight to save fuel。
