You are required to write at least 150 words but no more than 200 words.Part II Listening Comprehension (30 minutes)说明：201
2、7年6月大学英语六级考试全国共考了两套听力。本套的听力内容与第二套相同，因此本套听力部分不再重复给出。Part 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 the passage t
3、hrough 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.Questions 26 to 35 are based on the
4、following passage.Half of your brain stays 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
5、” than the network in the right side of the brain. 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 ears.It was (28)_ observed that the left side of the brain was more active during deep sleep
6、. When the researchers repeated the laboratory experiment 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 s
7、o that humans can defend themselves against any (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 exa
8、mple, dolphins, as well as other (33)_ animals, shut 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 suggests, another
9、 reason for dolphins keeping their eyes open during sleep is that they can look out for (35)_ while asleep. It also keeps their physiological processes working.A) ClassifiedB) ConsciouslyC) DramaticallyD) ExoticE) IdentifiedF) InherentG) MarineH) NovelI) PotentialJ) PredatorsK) ReferredL) SpeciesM)

Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph
11、more than once. Each paragraph is marked with 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
12、U.S. win at the International Math Olympiad (IMO)-the first for an American team in more than two decades-the 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 s
13、ocial and cultural factors play roles in determining 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
14、eventually begin to shift and become less exclusive.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 a
15、nd if “you realize thats how theyre growing, you 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, an
16、d university-based “math circles,” to prepare for the competitions.E One of the largest feeders for high school math competitions一including those that eventually lead to the IMOis a middle school program called MathCounts. About 100,000 students around the country participate in the programs competi
17、tion series, which culminates in a national game-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 2
18、24 students who make it to the national competition get an all- expenses-paid trip.F Nearly all members of last years winning U.S. IMO team took part in MathCounts as middle school students, as did Loh, the coach. “Middle school is an important age because students have enough math capability to sol
19、ve advanced problems, but they havent really decided 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. Stud
20、ents use forums to chat, play games, and solve problems 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 cour
21、ses on the site. Parents of advanced-math students and MathCounts 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 priceya three-week intensive program can cost $4,500 or moreb
22、ut most offer scholarships. The Math Olympiad 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 wr
23、itten tests and at the USA Math Olympiad.I Students 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 advan
24、ced mathematics for several hours after school 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 hav
25、e to know about them,” said Rusczyk. “Most people 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
26、 Mark Saul, the director of competitions for the Mathematical Association of America, not a single African-American or Hispanic studentand only a handful of girlshas ever made it to the Math Olympiad team in its 50 years of existence.Many schools simply dont prioritize academic competitions. “Do you
27、 know who we have to beat?” asked Saul.“The football team, the basketball teamthats 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
28、know about advanced-math opportunities like MathCountsand 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
29、runs a residential summer program aimed at getting 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 he
30、lps the students get into other elite summer 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,
31、 there are programs that are serving them, but theyre 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 t
32、o create that pathway.” Students apply to the 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, MathCounts added two new middle school programs to try to diversify its participant pool一the National Math Clu
33、b and the Math Video Challenge. Schools or teachers who sign up for the National Math Club receive a kit fall 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 m
34、ake a video illustrating a math problem and its real-world application. After the high-pressure Countdown round at this years national MathCounts 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 st
35、age to show their videos. The demographics of that group looked quite different from those in the competition roundof 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 desig
36、n. It also adds the element of artistic creativity 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 intere
37、st throughout the United States.38. Math circles 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 under served stu
38、dents learn advanced math.41. Winners of local 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-
39、off families.44. Some math training programs primarily focus on raising students math scores.41. 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
40、 statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.We live today indebted to McCa
41、rdell, Cashin, Hawes, Wilkins, and Maxwell, 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 play suits and other
42、 active wear outfits suffice for casual clothing, 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. Implicit
43、ly or explicitly, American fashion addressed 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 sportswea
44、r was not modeled on that of Europe, as “modem 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 ingen
45、uity and realistic lifestyle applications. Ease 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 h
46、er. American designers prized resourcefulness 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
47、 or no experience in justifying（月艮装）on 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 c
48、rude version of this relationship. The 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 trivial relationship to the fine arts. What the designers of American sportswear proved was that fashion is a genuine design art, answering to the demanding needs of service. Of course these practical
