[单项选择]Passage Five
This is supposed to be an enlightened age, but you wouldn’t think so if you could hear what the average men think of the average women. Women won their independence years ago. After a long, biter struggle, they now enjoy the same educational opportunities as men in most parts of the world. They have proved repeatedly that they are equal and often superior to men in almost every field. The hard-fought battle for recognition has been won, but it is by no means over. It is men, not women who still carry on the sex war because their attitude remains basically hostile. Even in the most progressive societies, women continue to be regarded as second-rate citizens. Hearing some men talk, you’d think that women belong to a different species. On the surface, the comments made by men about women’s abilities seem light-heartiness does not conc

[单项选择]

The picnics, speeches, and parades of today’ s Labor Day were all part of the celebration, held in New York City in 1882. Its promoter was an Irish-American labor leader named Peter J. McGuire. A carpenter by trade, McGuire had worked since the age of eleven, and in 1882 was president of the United Brotherhood of Carpenters and Joiners (UBCJ). Approaching the City’ s Central Labor Union that summer, he proposed a holiday that would applaud (赞许) "the industrial spirit—the great vital force of every nation. "On September 5 his suggestion bore fruit, as the estimated 10,000 workers, many of them ignoring their bosses’ warnings, left work to march from Union Square up Fifth Avenue to 42rid Street. The event gained national attention, and by 1893 thirty states had made Labor Day an annual holiday.
The quick adoption of the scheme may have indicated less about the state lawmakers’ respect for working people than about a fear of risking th

[单项选择]

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.
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 for
A. energy cost reduced in a formation of V-shape and echelon or otherwise
B. 25 birds might enjoy 71% less energy consuming
C. a naturalistic airline works well than clever designs and lightweight composites
D. Kroo and his group are opposites who think that buying new aircraft is wasteful
