2、英语六级真题全国共考了两套听力。本套即第三套的听力材料及第一套完全一样，只是选项的顺序不同而已，故本套不再重复给出。Part III Reading Comprehension (40 minutes)Section ADirections: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read th
3、e passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.Half of your brain stays
4、alert and prepared for danger when you sleep in a new place, a study has revealed. This phenomenon is often _26_ to as the “first-night-effect. Researchers from Brown University found that a network in the left hemisphere of the brain “remained more active than the network in the right side of the b
5、rain. Playing sounds into the right ears (stimulating the left hemisphere) of _27_ was more likely to wake them up than if the noises were played into their left ear.It was _28_ observed that the left side of the brain was more active during deep sleep. When the researchers repeated the laboratory e
6、xperiment on the second and third nights they found the left hemisphere could not be stimulated in the same way during deep sleep. The researchers explained that the study demonstrated when we are in a _29_ environment the brain partly remains alert so that humans can defend themselves against any _
7、30_ danger.The researchers believe this is the first time that the “first-night-effect of different brain states has been _31_ in humans. It isnt, however, the first time it has ever been seen. Some animal _32_ also display this phenomenon. For example, dolphins, as well as other _33_ animals, shut
8、down one hemisphere of the brain when they go to sleep. A previous study noted that dolphins always _34_ control their breathing. Without keeping the brain active while sleeping, they would probably drown. But, as the human study suggest, another reason for dolphins keeping their eyes open during sl

Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked wi
11、th a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Elite Math Competitions Struggle to Diversify Their Talent PoolA Interest in elite high school math competitions has grown in recent years, and in light of last summers U.S. win at the International Math Olympiad
12、 (IMO)-the first for an American team in more than two decadesthe trend is likely to continue.B But will such contests, which are overwhelmingly dominated by Asian and white students from middle-class and affluent families, become any more diverse? Many social and cultural factors play roles in dete
13、rmining which promising students get on the path toward international math recognition. But efforts are in place to expose more black, Hispanic, and low-income students to advanced math, in the hope that the demographic pool of high-level contenders will eventually begin to shift and become less exc
14、lusive.C “The challenge is if certain types of people are doing something, its difficult for other people to break into it, said Po-Shen Loh, the head coach of last years winning U.S. Math Olympiad team. Participation grows through friends and networks and if “you realize thats how theyre growing, y
15、ou can start to take action and bring in other students, he said.D Most of the training for advanced-math competitions happens outside the confines of the normal school day. Students attend after-school clubs, summer camps, online forums and classes, and university-based “math circles, to prepare fo
16、r the competitions.E One of the largest feeders for high school math competitionsincluding those that eventually lead to the IMOis a middle school program called Math Counts. About 100,000 students around the country participate in the programs competition series, which culminates in a national game
17、-show-style contest held each May. The most recent one took place last week in Washington, D.C. Students join a team through their schools, which provide a volunteer coach and pay a nominal fee to send students to regional and state competitions. The 224 students who make it to the national competit
18、ion get an all-expenses- paid trip.F Nearly all members of last years winning U.S. IMO team took part in Math Counts as middle school students, as did Loh, the coach. “Middle school is an important age because students have enough math capability to solve advanced problems, but they havent really de
19、cided what they want to do with their lives, said Loh. “They often get hooked then.G Another influential feeder for advanced-math students is an online school called Art of Problem Solving, which began about 13 years ago and now has 15,000 users. Students use forums to chat, play games, and solve pr
20、oblems together at no cost, or they can pay a few hundred dollars to take courses with trained teachers. According to Richard Rusczyk, the company founder, the six U.S. team members who competed at the IMO last year collectively took more than 40 courses on the site. Parents of advanced- math studen
21、ts and Math Counts coaches say the children are on the website constantly.H There are also dozens of summer campsmany attached to universitiesthat aim to prepare elite math students. Some are pricey-a three-week intensive program can cost $4,500 or morebut most offer scholarships. The Math Olympiad
22、Summer Training Program is a three-week math camp held by the Mathematical Association of America that leads straight to the international championship and is free for those who make it. Only about 50 students are invited based on their performance on written tests and at the USA Math Olympiad.I Stu
23、dents in university towns may also have access to another lever for involvement in accelerated math: math circles. In these groups, which came out of an Eastern European tradition of developing young talent, professors teach promising K-12 students advanced mathematics for several hours after school
24、 or on weekends. The Los Angeles Math Circle, held at the University of California, Los Angeles, began in 2007 with 20 students and now has more than 250. “These math circles cost nothing, or theyre very cheap for students to get involved in, but you have to know about them, said Rusczyk. “Most peop
25、le would love to get students from more underserved populations, but they just cant get them in the door. Part of it is communication; part of it is transportation.J Its no secret in the advanced-math community that diversity is a problem. According to Mark Saul, the director of competitions for the
26、 Mathematical Association of America, not a single African-American or Hispanic student-and only a handful of girls-has ever made it to the Math Olympiad team in its 50 years of existence. Many schools simply dont prioritize academic competitions. “Do you know who we have to beat? asked Saul. “The f
27、ootball team, the basketball team-thats our competition for resources, student time, attention, school dollars, parent efforts, school enthusiasm.K Teachers in low-income urban and rural areas with no history of participating in math competitions may not know about advanced-math opportunities like M
28、ath Countsand those who do may not have support or feel trained to lead them.L But there are initiatives in place to try to get more underrepresented students involved in accelerated math. A New York City-based nonprofit called Bridge to Enter Mathematics runs a residential summer program aimed at g
29、etting underserved students，mostly black and Hispanic, working toward math and science careers. The summer after 7th grade, students spend three weeks on a college campus studying advanced math for seven hours a day. Over the next five years, the group helps the students get into other elite summer
30、math programs, high-performing high schools, and eventually college. About 250 students so far have gone through the program, which receives funding from the Jack Kent Cooke Foundation.M “If you look at a lot of low-income communities in the United States, there are programs that are serving them, b
31、ut they re primarily centered around Lets get these kids grades up, and not around Lets get these kids access to the same kinds of opportunities as more-affluent kids, said Daniel Zaharopol, the founder and executive director of the program. “Were trying to create that pathway. Students apply to the
32、 program directly through their schools. “We want to reach parents who are not plugged into the system, said Zaharopol.N In the past few years, Math Counts added two new middle school programs to try to diversify its participant pool-the National Math Club and the Math Video Challenge. Schools or te
33、achers who sign up for the National Math Club receive a kit full of activities and resources, but theres no special teacher training and no competition attached.O The Math Video Challenge is a competition, but a collaborative one. Teams of four students make a video illustrating a math problem and i
34、ts real-world application. After the high-pressure Countdown round at this years national Math Counts competition, in which the top 12 students went head to head solving complex problems in rapid fire, the finalists for the Math Video Challenge took the stage to show their videos. The demographics o
35、f that group looked quite different from those in the competition round-of the 16 video finalists, 13 were girls and eight were African-American students. The video challenge does not put individual students on the hot seat-so its less intimidating by design. It also adds the element of artistic cre
36、ativity to attract a new pool of students who may not see themselves as “math people.36. Middle school is a crucial period when students may become keenly interested in advanced mathematics.37. Elite high school math competitions are attracting more interest throughout the United States.38. Math cir
37、cles provide students with access to advanced-math training by university professors.39. Students may take advantage of online resources to learn to solve math problems.40. The summer program run by a nonprofit organization has helped many underserved students learn advanced math.41. Winners of loca
38、l contests will participate in the national math competition for free.42. Many schools dont place academic competitions at the top of their priority list.43. Contestants of elite high school math competitions are mostly Asian and white students from well-off families.44. Some math training programs
39、primarily focus on raising students math scores.45. Some intensive summer programs are very expensive but most of them provide scholarships.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four
40、choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.We live today indebted to McCardell, Cashin, Hawes, Wilkins, and Maxwell,
41、and other women who liberated American fashion from the confines of Parisian design. Independence came in tying, wrapping, storing, harmonizing, and rationalizing that wardrobe. These designers established the modem dress code, letting playsuits and other active wear outfits suffice for casual cloth
42、ing, allowing pants to enter the wardrobe, and prizing rationalism and versatility in dress, in contradiction to dressing for an occasion or allotment of the day. Fashion in America was logical and answerable to the will of the women who wore it. Implicitly or explicitly, American fashion addressed
43、a democracy, whereas traditional Paris-based fashion was prescriptive and imposed on women, willing or not.In an earlier time, American fashion had also followed the dictates of Paris, or even copied and pirated specific French designs. Designer sportswear was not modeled on that of Europe, as “mode
44、m art would later be; it was genuinely invented and developed in America. Its designers were not high-end with supplementary lines. The design objective and the business commitment were to sportswear, and the distinctive traits were problem-solving ingenuity and realistic lifestyle applications. Eas
45、e of care was most important: summer dresses and outfits, in particular, were chiefly cotton, readily capable of being washed and pressed at home. Closings were simple, practical, and accessible, as the modem woman depended on no personal maid to dress her. American designers prized resourcefulness
46、and the freedom of women who wore the clothing.Many have argued that the women designers of this time were able to project their own clothing values into a new style. Of course, much of this argument in the 1930s-40s was advanced because there was little or no experience in justifying apparel(服装) on
47、 the basis of utility. If Paris was cast aside, the tradition of beauty was also to some degree slighted. Designer sportswear would have to be verified by a standard other than that of pure beauty; the emulation of a designers life in designer sportswear was a crude version of this relationship. The
48、 consumer was ultimately to be mentioned as well, especially by the likes of Dorothy Shaver, who could point to the sales figures at Lord & Taylor.Could utility alone justify the new ideas of the American designers? Fashion is often regarded as a pursuit of beauty, and some cherished fashions trivia
49、l relationship to the fine arts. What the designers of the American sportswear proved was that fashion is a genuine design art, answering to the demanding needs of service. Of course these practical, insightful designers have determined the course of late twentieth-century fashion. They were the pioneers of gender equity, in their useful,
