[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%。
