26 to 35 are based on the following passage.Half of your brain stays alert and prepared for danger when you sleep in a new place,a study hasrevealed.This phenomenon is often 26 to as the "first-night-effect".Researchers from BrownUniversity found that a network in the left hemisphere of the brain "remained more active"than thenetwork in the right side of the brain.Playing sounds into the right ears stimulating the lefthemisphere)of 27 was more likely to wake them up than if the noises were played into their leftears.It was 28 observed that the left side of the brain was more active during deep sleep.When theresearchers repeated the laboratory experiment on the second and third nights they found the lefthemisphere could not be stimulated in the same way during deep sleep.The researchers explained thatthe study demonstrated when we are in a 29 environment the brain partly remains alert so thathumans can defend themselves against any 30 danger.The researchers believe this is the first time that the "first-night-effect"of different brain states hasbeen 31 in humans.It isn't,however,the first time it has ever been seen.Some animal 32also display this phenomenon.For example,dolphins,as well as other 33 animals,shut down onehemisphere of the brain when they go to sleep.A previous study noted that dolphins always 34control their breathing.Without keeping the brain active while sleeping,they would probably drown.But,as the human study suggests,another reason for dolphins keeping their eyes open during sleep isthat they can look out for 35 while asleep.It also keeps their physiological processes working.A)classifiedI)potentialB)consciouslyJ)predatorsC)dramaticallyK)referredD)exoticL)speciesE)identifiedM)specificallyF)inherentN)varietiesG)marineO)volunteersH)novel2017.6/3(第2套)Section

information is derived.You may choose a paragraph more than once.Each paragraph is marked with a letter.Answer the questions by marking thecorresponding letter on Answer Sheet 2.Elite Math Competitions Struggle to Diversify Their Talent Pool[A]Interest in elite high school math competitions has grown in recent years,and in light of lastsummer's U.S.win at the Intemational Math Olympiad (IMO)-the first for an American team inmore than two decades-the trend is likely to continue.[B]But will such contests,which are overwhelmingly dominated by Asian and white students frommiddle-class and affluent families,become any more diverse?Many social and cultural factors playroles in determining which promising students get on the path toward intemational mathrecognition.But efforts are in place to expose more black,Hispanic,and low-income students toadvanced math,in the hope that the demographic pool of high-level contenders will eventuallybegin to shift and become less exclusive.[C]"The challenge is if certain types of people are doing something,it's difficult for other people tobreak into it,"said Po-Shen Loh,the head coach of last year's winning U.S.Math Olympiadteam.Participation grows through friends and networks and if "you realize that's how they'regrowing,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 normalschool day.Students attend after-school clubs,summer camps,online forums and classes,anduiversity-based "math circles,"to prepare for the competitions.[E]One of the largest feeders for high school math competitions-including those that eventually leadto the IMO-is a middle school program called MathCounts.About 100,000 students around thecountry participate in the program's competition 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 feeto send students to regional and state competitions.The 224 students who make it to the nationalcompetition get an all-expenses-paid trip.[F]Nearly all members of last year's winning U.S.IMO team took part in MathCounts as middleschool students,as did Loh,the coach."Middle school is an important age because students haveenough math capability to solve advanced problems,but they haven't really decided what theywant 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 ProblemSolving,which began about 13 years ago and now has 15,000 users.Students use forums to chat,play games,and solve problems together at no cost,or they can pay a few hundred dollars to takecourses 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 thesite.Parents of advanced-math students and MathCounts coaches say the children are on thewebsite constantly.[H]There are also dozens of summer camps-many attached to universities-that aim to prepare elitemath students.Some are pricey-a three-week intensive program can cost $4,500 or more-butmost offer scholarships.The Math Olympiad Summer Training Program is a three-week math campheld by the Mathematical Association of America that leads straight to the internationalchampionship and is free for those who make it.Only about 50 students are invited based on theirperformance on written tests and at the USA Math Olympiad.[I]Students in university towns may also have access to another lever for involvement in accelerated2017.6/4(第2套)math:math circles.In these groups,which came out of an Eastern European tradition ofdeveloping young talent,professors teach promising K-12 students advanced mathematics forseveral hours after school or on weekends.The Los Angeles Math Circle,held at the University ofCalifornia,Los Angeles,began in 2007 with 20 students and now has more than 250."These mathcircles cost nothing,or they're very cheap for students to get involved in,but you have to knowabout them,"said Rusczyk."Most people would love to get students from more underservedpopulations,but they just can't get them in the door.Part of it is communication;part of it istransportation.”[J]It's no secret in the advanced-math community that diversity is a problem.According to MarkSaul,the director of competitions for the Mathematical Association of America,not a singleAfrican-American or Hispanic student-and only a handful of girls-has ever made it to the MathOlympiad team in its 50 years of existence.Many schools simply don't prioritize academiccompetitions."Do you know who we have to beat?"asked Saul."The football team,thebasketball team-that's 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 competitionsmay not know about advanced-math opportunities like MathCounts-and those who do may nothave support or feel trained to lead them.[L]But there are initiatives in place to try to get more underrepresented students involved inaccelerated math.A New York City-based nonprofit called Bridge to Enter Mathematics runs aresidential summer program aimed at getting underserved students,mostly black and Hispanic,working toward math and science careers.The summer after 7th grade,students spend threeweeks on a college campus studying advanced math for seven hours a day.Over the next fiveyears,the group helps the students get into other elite summer math programs,high-performinghigh 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 areserving them,but they're primarily centered around 'Let's get these kids'grades up,'and notaround Let's 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."We're trying to createthat pathway.Students apply to the program directly through their schools."We want to reachparents 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 itsparticipant pool-the National Math Club and the Math Video Challenge.Schools or teachers whosign up for the National Math Club receive a kit full of activities and resources,but there's nospecial teacher training and no competition attached.[O]The Math Video Challenge is a competition,but a collaborative one.Teams of four students makea video illustrating a math problem and its real-world application.After the high-pressureCountdown round at this year's national MathCounts competition,in which the top 12 studentswent head to head solving complex problems in rapid fire,the finalists for the Math VideoChallenge took the stage to show their videos.The demographics of that group looked quitedifferent from those in the competition round-of the 16 video finalists,13 were girls and eightwere African-American students.The video challenge does not put individual students on the hotseat-so it's less intimidating by design.It also adds the element of artistic creativity to attract anew 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 advancedmathematics.37.Elite high school math competitions are attracting more interest throughout the United States.2017.6/5(第2套)
