1||F1F2|=c2=,故c=1.从而|DF1|=,由DF1⊥F1F2,得=+=,因此|DF2|=,所以2a=|DF1|+|DF2|=2,故a=,b2=a2﹣c2=1,因此,所求椭圆的标准方程为+y2=1;(Ⅱ)设圆心在y轴上的圆C与椭圆+y2=1相交,P1(x1,y1),P2(x2,y2)是两个交点,y1>0,y2>0,F1P1,F2P2是圆C的切线,且F1P1⊥F2P2,由圆和椭圆的对称性,易知x2=﹣x1,y1=y2,|P1P2|=2|x1|,由(Ⅰ)知F1(﹣1,0),F2(1,0),所以=(x1+1,y1),=(﹣x1﹣1,y1),再由F1P1⊥F2P2,得﹣+=0,由椭圆方程得1﹣=,即3+4x1=0,解得x1=﹣或x1=0.当x1=0时,P1,P2重合,此时题设要求的圆不存在;当x1=﹣时,过P1,P2,分别与F1P1,F2P2垂直的直线的交点即为圆心C,设C(0,y0)由F1P1,F2P2是圆C的切线,知CP1⊥F1P1,得•=﹣1,而|y1|=|x1+1|=,故y0=,故圆C的半径|CP1|==.综上,存在满足题设条件的圆,其方程为x2+=.点评:本题考查直线与圆锥曲线的综合问题,考查化归思想、方程思想分类讨论思想的综合应用,考查综合分析与运算能力,属于难题.21.已知函数f(x)=e x﹣1﹣ax(a∈R).(1)求函数f(x)的单调区间;(2)当x∈(0,2]时,讨论函数F(x)=f(x)﹣xlnx零点的个数;(3)若g(x)=ln(e x﹣1)﹣lnx,当0<a≤1时,求证:f[g(x)]<f(x).考点:导数在最大值、最小值问题中的应用;根的存在性及根的个数判断;利用导数研究函数的单调性.专题:计算题;证明题;分类讨论;函数的性质及应用;导数的综合应用.分析:(1)求函数f(x)的导数,对a讨论,分当a≤0时,当a>0时,令导数大于0,得增区间,令导数小于0,得减区间;(2)对F(x)=f(x)﹣xlnx进行化简,构造函数h(x)=﹣xlnx(x>0),研究函数h(x)的单调性和最值,即可确定F(x)=f(x)﹣xlnx在定义域内是否存在零点;(3)由(1)知,当0<a≤1时,f(x)在(0,+∞)上单调递增,要证明f(g(x))<f (x),只要证明g(x)<x即可.解答:解:(1)函数的定义域为(﹣∞,+∞),f′(x)=(e x﹣ax﹣1)′=e x﹣a.当a≤0时,f′(x)>0恒成立,即有f(x)在R上递增;当a>0时,由f′(x)<0,得e x﹣a<0,e x<a,∴x<lna,由f′(x)>0,得e x﹣a>0,e x>a,∴x>lna,所以函数的单调减区间为(﹣∞,lna),单调增区间是(lna,+∞).(2)函数F(x)=f(x)﹣xlnx的定义域为(0,+∞),由F(x)=0,得a=﹣lnx(x>0),令h(x)=﹣lnx(x>0),则h′(x)=,由于x>0,e x﹣1>0,可知当x>1,h′(x)>0;当0<x<1时,h′(x)<0,故函数h(x)在(0,1)上单调递减,在(1,2]上单调递增,故h(x)≥h(1)=e﹣1.又h(2)=当a=1时,对∀x>0,有f(x)>f(lna)=0,即e x﹣1>x,即>1,当e﹣1<a<<e﹣1时,函数F(x)有两个不同的零点;当a=e﹣1或a=时,函数F(x)有且仅有一个零点;当a<e﹣1或a时,函数F(x)没有零点;(3)由(1)知,当0<a≤1时f(x)在(0,+∞)上单调递增,且f(0)=0;∴对x>0时,有f(x)>0,则e x﹣1>ax;故对任意x>0,ln(e x﹣1)﹣ln(ax)>g(x)=ln(e x﹣1)﹣lnx>0;所以,要证f[g(x)]<f(x),只需证:∀x>0,g(x)<x;只需证:∀x>0,ln(e x﹣1)﹣lnx<x;即证:ln(e x﹣1)<lnx+lne x;即证:∀x>0,xe x>e x﹣1;所以,只要证:∀x>0,xe x﹣e x+1>0,令H(x)=xe x﹣e x+1,则H′(x)=xe x>0,故函数H(x)在(0,+∞)上单调递增.∴H(x)>H(0)=0;∴对∀x>0,xe x﹣e x+1>0成立,即g(x)<x,∴f[g(x)]<f(x).点评:本题以函数为载体,主要考查导数的几何意义,考查导数在研究函数的单调性和最值中的应用,考查恒成立问题的解决方法,属于中档题.。

It’s an instinct (本能) which can be woken up in times of emergency or need. When we feel that something is happening or about to happen by instinct, we’re using resources within the unconscious mind. When the resources of two persons’ unconscious minds link together intothe same frequency, we call it Telepathy.We can either send or receive Telepathy. If you know who is calling before you answer the ringing phone, you are probably a good receiver. If you think of a person and he/she calls you, you are most likely to be better at sending.You can easily put your abilities to the test. Think of somebody and will him or her to contact you. Be patient. The other person may not be a good receiver, but they should contact you much earlier than would normally be expected. Or whenever the phones rings, but try “feeling” who is contacting you. Don’t guess, but try to feel it with your mind. However, if neither of these work for you, that doesn’t mean that you have no ability of telepathy. As mentioned earlier, telepathy is most likely to turn up in case of emergency.Telepathy dreams often contain telepathic messages. Two people may both dream of the other and find that their dreams had a clear connection. These people are probably linking to each other’s unconscious mind.Telepathy & Relationships. The more people spend time together, the more likely they are to be able to link up to the other’s mind, specially when separated. There are two reasons for this. One is that they understand the other’s mind through time spent together; the other is that there is usually a strong desire to communicate. A mother will often sense that her child is in danger. This is due to the child’s eagerly wanting his or her mother, knowing that this person who would always want to be there for them, and the mother’s deep desire to protect her child from harm.56. Telepathy turns up when we ____.A. sense a close friend in dangerB. use the five senses togetherC. recall things from our memoryD. think of a stranger57. You’re better at sending than receiving Telepathy if you ____.A. can feel your mom is in dangerB. receive a friend’s call as you wishC. can tell who knocks at your doorD. dream of a friend dreaming of you58. Which is not the way to help people gain Telepathy?A. Help them have a strong desire to communicate.B. Separate them all the time.C. Help them link up their unconscious minds.D. Let them spend much time together.B59. What does Passage①tell us about the boy?A. He was injured in the head when he was 14.B. He has waited for the payout for a long time.C. He has lived the same place since the accident.D. He was run over by a taxi when riding on the pavement.60. What can we learn about Lee and Collier counties from Passage②?A. They both became safe places.B. They won the same place in a race.C. They had the same number of accidents.D. They joined hands in reducing accidents.61. Which passage would give more information on the prevention of road accidents?A. ①B. ②C. ③D. ④CIn only two decades Asian Americans have become the fastest growing U. S. minority. As their children began moving up through the nation schools, it became clear that a new class of academic achievers was emerging. Their achievements are reflected in the nation’s best universities, where mathematics, science and engineering departments have taken on a decidedlyAsian character. This special liking for mathematics and science is partly explained by the fact that Asian-American students who began their education abroad arrived in the U. S. with a solid grounding in mathematics but little or no knowledge of English. They are also influenced by the promise of a good job after college. Asians feel there will be less unfair treatment in areas like mathematics and science because they will be judged more objectively. And the return on the investment in education is more immediate in something like engineering than with an arts degree.Most Asian-American students owe their success to the influence of parents who are determined that their children take full advantage of what the American educational system has to offer. An effective measure of parental attention is homework. Asian parents spend more time with their children than American parents do, and it helps. Many researchers also believe there is something in Asian culture that breeds success, such as ideals that stress family values and emphasize education.Both explanations for academic success worry Asian Americans because of fears that they feed a typical racial image. Many can remember when Chinese, Japanese and Filipino immigrants were the victims of social isolation. Indeed, it was not until 1952 that laws were laid down giving all Asian immigrants the right to citizenship.62. While making tremendous achievements at college, Asian-American students .A. feel they are mistreated because of limited knowledge of EnglishB. are afraid that their academic successes bear a strong Asian characterC. till worry about unfair treatment in societyD. generally feel it a shame to have to depend on their parents63. What are the major factors that determine the success of Asian Americans?A. A solid foundation in basic mathematics and Asian culture.B. Hard work and intelligence.C. Parents’ help and a limited knowledge of English.D. Asian culture and the American educational system.64. Few Asian American students major in human sciences mainly because .A. their English is not good enoughB. they are afraid they might meet with unfair judgment in these areasC. there is a wide difference between Asian and Western culturesD. hey know little about American culture and society65. Why do “both explanations” (Para. 3) worry Asian Americans?A. They are afraid that they will again be isolated from American society in general.B. People will think that Asian students rely on their parents for success.C. Asian Americans will be a threat to other minorities.D. American academic achievements have taken on too strong an Asian character.DHow to eat healthfully can be especially complex for working women who often have neither the desire nor the time to cook for themselves (or for anyone else). Registered dietitian(营养专家) Barhara Morrissey suggests that a few simple rules can help.“Go for nutrient dense foods,” she suggests, “foods that contain a multiple of nutrients. For example, select whole wheat bread as a breakfast food, rather than coffee cake. Or drink orange juice rather than orange drink, which contains only a small percentage of real juice-the rest is largely colored sugar water. You just can’t compare the value of these foods, the nutrient dense ones are so superior, ”she emphasizes.Morrissey believes that variety is not only the spice of life—it’s the foundation of a healthful diet. Diets which are based on one or two foods are not only virtually impossible to keep up the strength, they can be very harmful, she says, because nutrients aren’t supplied in sufficient amounts or balance.According to Morrissey, trying to find a diet that can cure your illnesses, or make you superwoman is a fruitless search. As women, many of us are too concerned with staying thin, she says, and we believe that vitamins are some kind of magic cure to replace food.“We need carbohydrates, protein and fat—they are like the wood in the fireplace. The vitamins and minerals are like the match, the spark, for the fuel,” she explains. “We need them all, but in a very different proportions. And if the fuel isn’t there, the spark is useless.”66. From the paragraph we know that working women.A.think cooking is especially complicatedB.do not share the same views with registered dietitiansC.are busy and not interested in cookingD. are likely to eat healthfully67. Orange juice is different from orange drink in that .A. it contains only a small percentage of real juiceB. it is natural, nutritious and prepared from real orangesC. it is largely orange-colored sugar waterD. it produces nothing but calories68. In Paragraph 4, “a fruitless search” means .A. an effort with no resultsB. a search for a diet without fruitsC. a research on fruitless dietD. a diet serving as medicine69. Many women take it for granted, according to passage that .A. a balanced diet can result in being fatB. staying thin and healthy are both possibleC. lack of variety in diets leads to staying thinD. vitamins are some kind of substitutions for food70. By “if the fuel isn’t there, the spark is useless”, the author means .A. carbohydrates, protein and fat are enough to support a human lifeB. vitamins and minerals are virtually of no valueC. carbohydrates, protein and fat are as important as vitamins and mineralsD. without carbohydrates, protein and fat, vitamins and minerals are of no useEMicrowaves may be great at warming up food, but what about warming people?Using microwaves to directly heat owners of a room would save much of the energy wasted by heating walls and furniture. And despite popular ideas about microwaves, this technique would be safe, according to Charles R. Burlier of the Microwave Research Center in Marlborough, New Hampshire. Low-power microwaves only penetrate (贯穿) the skin (low-power microwave penetration in a ham is about 0.2 inches, for example) and with no negative effects.To test this idea, Buffler subjected himself to microwaves in a special room using a standard 500-watt, 2459 MHz magnetron (磁控管). He found that a person will start to feel warmth at about 20 milliwatts per square centimeter (mw. / sq. cm. ) ; a satisfactory feeling of warmth occursbetween 35 and 50mw. / sq. cm. By comparison, a person standing in noonday summer sun feels the amount of 85 mw. / sq. cm. And a frozen meat pie in your microwave oven receives about 1000 mw. / sq. cm.In houses of the future, each room could be provided with its own magnetron, says Buffler. When you stepped into the living room, for example, a motion detector would turn on the magnetron, filling the room with low-power microwaves. In the same way that a microwave oven heats up a hamburger, but not the plate it’s on, you would feel warmth from the microwaves without changing the temperature of your coffee table. (You could, however, make your favorite easy chair even more comfortable by treating it with a radiation-absorbing chemical. ) While it might be some time before homeowners are comfortable enough with the idea to set up whole-body microwave heaters in houses, Buffler says microwaves may attract livestock farmers. Lambs that are born outdoors in winter, for example, are frequently lost to cold. Microwaves could warm the lambs safely and quickly.71. Which of the following can tell the main idea of the passage?A. A new heating system.B. A new microwave oven.C. A popular technique.D. The magnetron.72. According to paragraph 2, which of the following does not describe the characteristics of a microwave heater?A. It directly heats people in a room.B. It heats walls and furniture in a room.C. It is safe.D. It saves energy.73. The test conducted by Buffler shows that when a person feels comfortable warmth, he receivesabout______.A. 20 mw. / sq. cm.B. 40 mw. / sq. cm.C. 60 mw. / sq. cm.D. 85 mw. / sq. cm.74. According to paragraph 4, which of the following fills the room with low-power microwaves?A. The magnetron.B. The motion detector.C. The microwave oven.D. The radiation-absorbing chemical.75. Which of the following statements about microwave heaters would Buffler most probablyagree with?A. Microwave heaters will soon be widely used by homeowners.B. Microwave heaters sometimes make people feel uncomfortable.C. Perhaps microwave heaters will be first used by livestock farmers, who wish to protecttheirlambs in winter.D.Microwave heaters cannot be accepted by the public because they are somewhat unsafe.第二卷(共二部分45分)第一节:阅读表达(共15分)Some people think that Lei Feng, a soldier in the People’s Army, lived during the 1950s and 1960s, whose spirit inspired the people throughout the country embrace altruism(利他主义) and do good things for society, but now it seems out of date since we are living in quite a different society.I, however, ___________. As times change, the interpretation of the “Lei Feng Spirit” has now far exceeded the narrow scope of altruism. Today’s Chinese society is haunted by many social worries, such as people’s indifference to each other, confusion over moral standards and distortion of social values. There is something in Lei Feng spirit that can help solve some of modern China’s most pressing problems─namely the reform of state owned enterprises, which has led to redundant workers.Lei Feng put the interests of the country first, and was always ready to make sacrifices. He was never overwhelmed by different situations, but often encouraged people to help and love each other. His spirit can keep the people in a good mood and help us ease social tension. In the eyes of the general public, the Lei Feng Spirit represents sincerity, kindness and purity. We wish to use it to purify our society.1.What is the best title of the passage?

that she had written a narrator‟s part to the play,and asked me to switch 25.Her words,26 delivered,still stung(刺耳),especially when I saw my 27 go to another girl.I didn‟t tell my mother what had

told her what had happened.“But you will be a 38 narrator,”she said,reminding me of how much I loved to read stories aloud to her,“The narrator‟s part is as 39 as the part of the princess.”Over the

agreement第二部分阅读理解(共25小题;每小题2分,满分50分)ANelson Mandela was a figure of international fame,and many details of his life and career were public knowledge.But here are some things you may not have known about him.In his youth,Mandela enjoyed boxing.Even during the 27 years he spent in prison,he would exercise every morning.“I did not enjoy the violence of boxing so much as the science of it.Boxing is equal.I never did any real fighting after I entered politics.My main interest was in training,”he wrote in his autobiography Long Walk to Freedom.Among the memorabilia in the Mandela Family Museum in Soweto,visitors can find the world championship belt given to Mandela by American boxer Sugar Ray Leonard.Rolihlahla Mandela was nine years old when a teacher at the primary Methodist school where he was studying, gave him an English name—Nelson—in accordance with the custom to give all school children Christian names.Rolihlahla is not a common name in South Africa.It means “troublemaker”.His circumcision name was Dalibunga,meaning “founder of the Bunga”.However, in South Africa, Mr Mandela was often called by his clan(宗族)name—Madiba—which South Africans used out of respect.After going underground because of his ANC activities,Mr Mandela‟s ability to evade(躲避)the securities services earned him the nickname “the black Pimpernel”,after the novel The Scarlet Pimpernel,about a hero with a secret identity.A fake(伪造的)passport in the name of David Motsamayi was used by Mr Mandela. He had disguised himself as a driver,a gardener and a chef in order to travel around the country unnoticed by the authorities.Mr Mandela studied law on and off for 50 years from 1939,failing about half the course he took.In August 1952,he and Oliver Tambo established South Africa‟s first black law firm,Mandela and Tambo,in Johannesburg.He persevered to finally secure a law degree while in prison in 1989.41.Why did Nelson Mandela become a boxing fan?A.He enjoyed the violence of boxing.B.He wanted to take the championship.C.He desired to enjoy the training.D.He hoped to find a better job.42.Which of the following is true of Mandela‟s name?A.His original name was not Nelson.B.His parents gave him the name—Nelson.C.Rolihlahla is a popular name in South Africa.D.Madiba was his Christian name.43.What made people call Mr Mandela “the black Pimpernel”?A.His ability to escape from being caught.B.His underground activities in ANC.C.His pressure given by the authorities.D.The novel‟s hero with a secret identity.44.Mr Mandela made a fake passport to_____.A.travel around the country B.escape from the authoritiesC.disguise himself as an actor D.go abroad easily45.What can we learn from the last paragraph?A.It took Mr Mandela over fifty years to get a law degree.B.Mr Mandela set up South Africa‟s first law firm.C.Mr Mandela got his law degree after being released from prison.D.Mr Mandela was a determined person.BTraffic problems are an everyday concern in many cities,including Washington,DC.A growing number of Washingtonians are turning to bicycles to get to and from work.In fact,the number of commuters who use bicycles has doubled in the city since 2007.Ralph Buehler teaches urban planning at the Virginia Polytechnic Institute and State University,popularly known as Virginia Tech.He has written a book about urban biking,called “City Cycling,”He says there is a reason why urban bike tiding is now becoming more popular.“Over the last 60 to 70 years,cities in the U.S.have been adapted to the automobile.”“Most citi es took advantage of the money coming for the interstate highway system,from the federal government,starting in 1956.There was a 90 percent federal match(补贴)so the cities only had to put up 10%.It was very tempting.”In the years after World War Two,many Americans moved to suburban communities,just outside major cities. They decided to travel great distances to and from work in exchange for a home in the suburbs.Their cars became a symbol of freedom.But today,many people believe they can save money by living in the city.Greg Billing is with the Washington Area Bicyclist Association.“Wh en a person makes a change from using a car to using a bike,they are saving anywhere between 8 or$9,000 a year.”Ralph Buehler says governments save money when people use bicycles.“Building bicycling facilities is much cheaper than building and maintaining road facilities or public transport.”Washington,DC has also taken steps to protect bike riders.It approved a safe passing law and created areas on the road between cars and bikes.The United States Census Bureau says 4%of the city‟s workers ride to work by bike.The only city on the East Coast with more bike commuters is New York.46.What‟s the best title of the text?A.Traffic problems are an everyday concern in many citiesB.Bicycling to work in Washington,DC grows in popularityC.Bikes result in new problems in Washington,DCD.Washington,DC has taken steps to protect bike riders47.What can we know from Ralph Buehler‟s statement?A.The federal government supported building public transport.B.Government invested a lot to build bicycling facilities.C.Cities didn‟t use the money from the government wisely.D.Urban biking has been popular in the last 60 to 70 years.48.In the years after World War Two,many Americans prefer to_____.A.live in the city B.live in the suburbsC.travel great distances D.rent houses49.What do Ralph Buehler and Greg Billing agree with?A.Money can be saved when people use bicycles.B.Living in the city is much cheaper than in the country.C.Government should build more bicycling facilities.D.Road facilities and public transport develop rapidly now.50.What can we infer from the text?A.Traffic problems are the most severe in Washington,DC.B.4%of Washingtonians ride to work by bike in Washington,DC.C.Washington,DC concerns about the safety of bike riders.D. Many cities on the East Coast have bike commuters.CImagine a school where there are no academic requirements,no curriculum,and no tests.Children have total control of their education and are free to do what they want all day,every day.Sudbury Valley School in Framingham,Massachusetts has been operating this way since 1968.More than 30 schools worldwide have imitated the Sudbury model,and over 200 schools identify similarly as “democratic schools.”These schools are designed based on the belief that children have an innate curiosity to learn and do best when they direct their own learning.Sudbury Valley School admits anyone who wants to enroll(注册)between the ages of 4 and 18.Many parents send their kids from a young age because they believe that kids do best when they learn what they want to learn.Other students come to Sudbury because they had various issues in traditional school systems including rebellion,learning difficulties,and emotional problems.Sudbury is administered through a democratic process where every student and staff member hasan equal vote.In fact,students outnumber staff 20 to 1.There‟s no age segregation(差别);four-year-olds can hang out with teenagers.Many staff members are part time and have rich careers as historians,businessmen,psychologists,artists,among others.Learning is self-directed and occurs informally through having conversations,starting projects, reading for enjoyment,and playing games.If students are interested in a particular topic,they work with staff and other students to organize courses and find resources.The requirement for getting a high school diploma is to write an essay about how they are prepared to be an adult.95%of students graduate.90%of graduates end up going to college,better than the national average of 66%.Most graduates say that they benefited from a self-directed education because they were more motivated than their peers,lacked fear of authority figures,and got a head start in their field of interest.They work hard at doing the things they love to do.51.From Paragraph 1,we can know that_____.A.there are curriculums and tests in the schoolB.children can control their education freely in the schoolC.the school has been a “democratic school” for 50 yearsD.the school thinks their children lack curiosity52.Paragraph 2 mainly talks about_____.A.How parents send their children thereB.When parents send their children thereC.What children do in Sudbury Valley SchoolD.Why parents send their children there53.Which of the following shows the school is democratically managed?A.Students have the same right as staff in voting.B.There are as many students as staff members.C.The students are of the same age.D.All staff members work part-time.54.How can the students in Sudbury get their diploma?A.By having conversations.B.By reading for enjoyment.C.By playing games.D.By submitting a qualified paper.55.Most graduates‟attitude towards Sudbury Valley School‟s education might be ____.A.unclear B.negative C.positive D.doubtfulDHow many hours do you spend sitting in a chair every day? Eight hours in the office plus three hours in front of the TV after work is the norm for many people.You probably don‟t need an expert to tell you that sitting too much is not good for your health—from an increased risk of heart disease and obesity in the long term,to reduced cholesterol(胆固醇)maintenance in the short term,not to mention the strain on your neck and spine.To make matters worse,many researches show a good diet and regular exercise can‟t reduce the negative effects of sitting too much.A 2010 study of nearly 9,000 Australians found that for each additional hour of television a person watched per day,the risk of dying rose by 11 percent.Another study tracked the health of 123,000 Americans between 1992 and 2006.The death rate for men who spent six hours or more per day sitting was about 20 percent higher than for men who sat for three hours or less.So what can we do about it? Health experts suggest we break up those many hours spent sitting with more hours spent standing.The BBC conducted a simple experiment with a group of 10 volunteers who usually spent most of the day sitting.They were asked to stand for at least three hours a day.The researchers took measurements Oil days when the volunteers stood,and when they sat around.When they looked at the data there were some striking differences,the BBC reported.Blood sugar leveled off much quicker on the days when the study subjects stood compared with the days they spent in a chair.Standing also burned more calories——about 50 calories an hour.A member said although doing exercise offers many proven benefits,our bodies also need the increase in muscle activity that standing provides.The researchers believe that even small adjustments,like standing while talking on the phone,will help.56.The underlined word “norm” in Paragraph 1 most probably means____.A.standard answer B.cause C.excuse D.reasonable explanation57.What bad effect does sitting too much have?A.A low risk of heart disease.B.Becoming too fat.C.Balanced cholesterol maintenance.D.Benefiting your neck and spine.58.What‟s the main idea of Paragraph 4?A.Sitting is killing us.B.We should have a good diet.C.Watching TV does us no good.D.Women have higher death rate than men.59.What is the purpose of the experiment in the text?A.To help the 10 volunteers to lose weight.B.To find the difference between standing and sitting.C.To prove the benefit of standing.D.To teach us how to control blood sugar.60.What would be the best title for the text?A.Having regular exercise B.Standing up for healthC.Watching less TV D.Increasing muscle activityEGimmicky—and expensive—new gloves allow chatterboxes to take the term …handsfree‟ to a new level—by talking into them as they make a call.The gloves are known as …Talk to the Hand‟ and cost£1,000 a pair.They come with a speaker unit embedded(嵌入)into the thumb and a microphone built into the little finger that can be connected to any mobile handset using Bluetooth.Artist Sean Miles designed the gloves that double as a phone in part of his project that shows the possibilities of gadget(小机件)recycling.He combines gloves with parts from mobile handsets recycled through O2,which commissioned the project.Mobile phone users will be able to keep their hands warm while they chat without taking their phone out of their pocket or handbag.Mr Miles designed two pairs of the new gloves—one in pink and the other in brown and yellow.They will appear in an exhibition this July and visitors will be able to win the gloves.If demand is high,they will then be produced on a larger scale.O2 Recycle,which backs the project,estimates that there are already 70 million unused mobile handsets in the UK.The service pays those who recycle gadgets including phones,MP3 players and digital cameras.Designer Scan Miles,hopes his work will get people thinking about recycling.The 41-year-old said:“I hope that my Talk to the Hand project will ge t people to think again about the waste created by not recycling gadgets.If a few more people recycle their gadgets rather than send them to landfill(垃圾场),I think this project will have fulfilled its aim.”The Talk to the Hand mobile phone gloves are the second product in a series that O2 Recycle and Miles have created.Miles is now working on combining phones with handbags—so people don‟t spend time rummaging(翻查)around in their bags to find a phone when it rings.61.For what purpose is the text written?A.To show the harmfulness of old handsets.B.To introduce Sean Miles‟ new designs.C.To warn people not to throw electronic waste.D.To ask more people to join O2 Recycle.62.What‟s the main idea of Paragraph 3?A.How the new gloves are designed.B.What the gloves are made of.C.Who designed the gloves.D.How O2 Recycle is managed.63.What can we learn about Talk to the Hand?A.It has been widely used at present.B.It has a pair of gloves that can function as a phone.C.It can be connected directly to any mobile handset.D.It is expensive but environment—friendly.64.Which of the following is true of O2 Recycle?A.It encourages people to recycle gadgets.B.It has recycled 70 million mobile handsets.C.It promotes the technology of IT.D.It is now recycling gadgets around the world.65.What is the passage mainly about?A.New mobiles that are fashionable.B.Sean Miles who set up a phone company.C.Outdated gadgets that can be used for recycling.D.New gloves that can be used for making phone calls.第II卷(共45分)第三部分书面表达(共两节,满分45分)第一节阅读表达(共5小题;每小题3分,满分15分)阅读下面的短文,并根据文章后的要求答题。

A(2015年吉林长春高三新起点调研考试英语试卷)In 1975, George Carlin appeared on a popular TV show, Saturday Nig ht Live, with his famous words about blue food. “Why is there no blue food? I can’t find blue food—I can’t find the flavor of blue! I mean yellow is lemon; orange is orange and red is cherry. W here is the blue food? ”Well, Carlin pretty much has it right—there’s not no blue food, but there’s certainly not a lot of it. Fresh-picked blueberries are blue, though they become purple when they are turned into jam. The blue in blueberries—like the purple in grapes and the red in tomatoes—is found in nature. But i t isn’t a hot color for food. People don’t seem to prefer blue food. Some diet programs even suggest thatthose determined to lose weight should make their food blue.Eating, in part, begins with our eyes. Charles Spence—an experimental psychologist from Oxford University—points out that color can change our taste experience. Commonly, we consider red-colored foods up to 20% sweeter than they actually are; and green foods as being more sour. Spence suggests: human expectations may be influenced by our long history of watching - green fruits can become sweet as they grow up and turn red.But what about blue? Except blueberries, much of the blue food we see these days is dyed blue artificially. Food producers argue that artificial color doesn’t do much harm to health. A lot of research shows that some physical problems of kids are related to food dyes—while other studies show no effects at all. Blue birthday cake or even blue-dyed chicken can be served on the dinner table. So what?21. George Carlin’s words a re placed at the beginning of the passage to _______.A. show the author’s opinionB. introduce a TV showC. tell a famous personD. lead in the topic22. Which of the following statements of blue is true?A. Blueberries are always blue, whether fresh or not.B. The blue in blueberries is found unnatural.C. Blue is not a very popular color for foods.D. People often feel cold when they eat blueberries.23. Eating sometimes begins with our eyes because _______.A. our taste experience can be influenced by colorB. red-colored food are 20% sweeter than green foodC. people prefer red-colored food to green foodD. before eating, people watch food for a long time24. The underlined words “is dyed” in Para. 4 are closest in meaning to “_______”.A. is eaten upB. has grown upC. is changed in colorD. is harmful toB(2015•甘肃省部分普通高中高三2月第一次联考)A ground-based system that uses much stronger signals than GPS can find your location in cities and indoors. It is a new positioning system that could compete with GPS to make sure you never lose your directions again.Instead of satellites, Locata uses ground-based equipment to launch a radio signal over a localized area that is a million times stronger on arrival than GPS. It can work indoors as well as outdoors, and the makers claim the receivers can be shrunk to fit inside a regular cell phone. Even the US military, which invented GPS technology, signed a contract last month agreeing to a large-scale test of Locata at the White Sands Missile Range in New Mexico.“This is one of the most important technology developments for the future of the positioning industry,” says Nunzio Gambale, CEO and co-founder of the firm Locata, based in Griffith, Australia.As for the Locata’s accuracy, Christopher Morin of the US Air Force tested it recently at White Sands, and it worked to within 18 centimeters along any axis(轴). Morin says it should be possible to get the resolution down to 5 centimeters.Admittedly, the tests were performed in an open desert where GPS also works beautifully, but its signals are weak—like a car headlight from 20,000 kilometers away—and easily blocked by solid objects. “Locata’s signal is far stronger, though not guaranteed to work in a complex urban environment,” says David Last, consultant to the UK’s General Lighthouse Authorities.“Locata’s technology will face competition in the race to transform indoor navigation. But it could shine in specific areas,” Gambale says. “Robots with Locata could easily navigate inside buildings without the complex optical systems they need at the moment. And process that handle precise location data could not only guide you around a mall, railway station or airport, but also take you to the exact shelf in a shop for the product you want. The units small and cheap enough for smart phones should be available within five years— a similar path to the one GPS took on its way towards world domination.”25. The passage is written mainly to .A. encourage people to buy the LocataB. tell us the disadvantage of the GPSC. introduce a new positioning system LocataD. tell us that Locata will replace GPS one day26. Which of the following is not true about Locata according to Paragraph 2?A. Without the help of the satellites, Locata can tell you where you are.B. The US military has to test it before using it.C. Locata has a better signal than GPS.D. Locata can be fixed into smart phones only.27. Which of the following words can be used to replace the underlined word in Paragraph 4?A. accuracyB. speedC. determinationD. length28. According to the passage, what can we know about Gambale?A. He did the experiment at White Sands.B. He is confident in Locata and think highly of it.C. He said that Locata could not work in a complex urban environment.D. He is worried about the competition that Locata faces.C(江西省重点中学盟校2015届高三第一次十校联考)How do you celebrate New Year’s Day? If I had to take a guess, you probably celebrate New Year’s Day surrounded by family and friends, enjoying drinks of your choice (probably wine and champagne) and watching the ball drop. If you’re particularly lucky, perhaps you share a kiss with that special someone when the clock hits 00:00am.Have you ever imagined how New Year’s Day would look in another country? Listed below are five of the top ten “Unique New Year Traditions from Around the World.”1. Breaking Dishes on Neighbor’s Door——DenmarkA strange and weird Danish New Year tradition, depending on how you look at it, is throwing dishes at neighbor’s door. Strangely, this makes them happy instead of annoying them. The family with the tallest tower of broken plates, glasses, cups and other crockery is considered to be the luckiest person because it symbolizes their large amount of loyal friends.2. Talking to Spirits——MexicoTalking to spirits is a part of Mexican belief. Mexicans strongly believe that they can communicate with the souls of their dead loved ones. New Year’s Eve is considered the best time to communicate with dead spirits to convey a message or ask for guidance. And this is not done at home on anindividual basis but is a legal Mexican practice. Taos Inn, in New Mexico for example, offers 15 minutes session of spiritualism and meditation for $15. Not a bad price for some helpful guidance!3. Wearing Polka Dots ——PhilippinesImagine streets full of people wearing polka dots and dining room tables full of round shaped food and fruits on one single day of the year. This all actually happens in the Philippines on New Year’s Eve every year. Philippines believe that this will bring them prosperity by associating the round dots to coins and wealth.4. Burning Scarecrow(稻草人)Dummy——EcuadorEcuador has a unique custom of crafting scarecrows and then burning them at midnight. They adorn them and fill the scarecrows with newspapers and pieces of wood. As midnight approaches, everyone gathers outside their home and each family burns their own scarecrow. The tradition says that this destroys all the bad things that took place in the past 12 months. The scarecrow also scares away bad luck, which in turn, fills their new year with luck and happiness.5. Mistletoe(槲寄生)Leaves Are Placed Under Pillow to Find Husband——IrelandThe single women of Ireland wait desperately for New Year’s Eve because it is the night that can bring them the love of their lives. They place mistletoe leaves under their pillow hoping to catch their future husband. It is also believed in the Irish culture that this act will help them get rid of bad luck.The world is a large and very different place. Yes, people of all nations may celebrate New Year’s much differently around the world, with different traditions, but there are a lot of general themes to be seen. We all want to start a new, fresh year with renewed enthusiasm and hope no matter what happened during the past year. We all want to be happier, find love, renew friendships increase our wealth and also hope for a little extra luck in the coming new year.29. When New Year’s Day is coming, people always celebrate it in many ways EXCEPT __________.A. sharing the time with their loversB. getting together with their familiesC. setting the ball dropD. enjoying drinks with their friends30. What can you learn when you are paying a visiting to Mexico during New Year’s Day?A. It’s commonly believed that the dead have spirits and souls l iving around.B. It’s New Year’s Day that Mexicans consider the best time to talk to spirits.C. You’d better talk to your ancestors just at home secretly, or you’ll break the law.D. You can ask for help free when you want to talk to the dead.31.

ARecently a study, led by Pedro Hallal of the Federal University, suggests that nearly a third of adults, 31%, are not getting enough exercise. That rates of exercisehave declined is hardly a new discovery. Since the beginning of the industrial revolution, technology and economic growth have helped to create a world in which taking exercise is more and more an option rather than a necessity. But only recently have enough good data been collected from enough places to carry out the sort of analysis Dr Hallal and his colleagues have engaged in.There are common themes in different places. Unsurprisingly, people in rich countries are less active than those in poor ones, and old people are less active than young ones. Less obviously, women tend to exercise less than men—34% are inactive, compared with 28% of men. But there are exceptions. The women of Croatia, Finland, Iraq and Luxembourg, for example, move more than their male countrymen.Malta wins the race for most slothful country, with 72% of adults getting too little exercise, and Swaziland and Saudi Arabia are in close behind, with 69%. In Bangladesh, just 5% of adults fail to exercise enough. Surprisingly, six Americans in ten are active enough according to Dr Hallal’s study, compared with fewer than four in ten British.These high rates of inactivity are worrying. Human beings seem to have evolved(进化) to benefit from exercise while deliberately avoiding it whenever they can. In a state of nature it would be impossible to live a life that did not provide enough of it. But that is no longer the case. Actually lack of enough activity these days has nearly the same effect on life span(寿命) as smoking.21. We may learn from Paragraph 1 that_________.A. the decline of exercise rates is newly discoveredB. the study suggests 31% of female adults get too little exerciseC. the good enough data has been collected from only one countryD. the industrial revolution has changed the way people live to some degree22. According to the study, women of Luxembourg_________.A. have little time to exerciseB. hate to get regular exerciseC. take more exercise to lose weightD. exercise more than men in their country23. The underlined word “slothful” in Paragraph 3 most probably means_________.A. powerfulB. richC. lazyD. unpopular24. What can be the best title for the text?A. Worldwide Lack of Enough ExerciseB. New Health DiscoveryC. Evolvement of Human BeingsD. Benefits of Taking ExerciseBFAMILIES often get caught up in the competitive college admissions process. However, if you’re willing to look beyond the super-selective (非常挑剔的) top colleges, you’ll find that colleges nee d you more than you need them.A survey conducted by American website Inside Higher Ed found that 79 percentof colleges in the US were either “very or moderately (适度地) concerned” about not meeting their enrollment (招生) goals this year. And that’s up from 76 percent last year. Private nonprofit colleges particularly felt this way.According to Scott Jaschik, editor of Inside Higher Ed, it’s the “non-famous privates” that are struggling the most. Without big donations , they’re forced to rely much more on tuition payments to cover costs.Many of these colleges are often willing to offer bigger discounts or may match competing schools’ offers of financial aid. Knowing this information ahead of time can greatly change a student’s college list. If you know that your ranks are in the top 25 percent (above the college’s middle 50 percent), you have: 1) a much greater likelihood of being accepted, and 2) a reasonably good chance that you’ll be offered an attractive financial aid package.The problem is that most families never look beyond the colleges in one area or the top schools nationally. But depending on the student’s academic and after-class performance, the student may be considered a much more desirable (值得拥有的) applicant somewhere else, and that desirability is often rewarded with money.Make your list and check it twice. It’s not unusual to hear of students applying to 15, 18, or even 23 colleges. But there is no way a student can apply to that many colleges and do a good job on each one.The college admissions process doesn’t need to be crazed. If you understand what makes you desirable, as well as your financial limitations, and you are willing to look at colleges with an open mind, the process can be very rewarding.25. What is the author’s main pu rpose in writing this article?A. To point out the problems facing private nonprofit colleges in the US.B. To inform the readers of a new survey of private nonprofit colleges in the US.C. To advise college applicants to look beyond top colleges when choosing where to study.D. To tell college applicants how to increase their likelihood of getting financial aid.26. According to the article, many private nonprofit colleges in the US ______.A. receive huge donations from corporations and individualsB. are struggling to achieve their enrollment goalsC. don’t rely much on tuition payments to cover costsD. are becoming more popular with college applicants than ever27. What does the author think students should do when making their college lists?A. They should focus only on colleges in one area.B. They should choose top colleges all across the US.C. They should apply to as many colleges as they can.D. They should look at colleges with an open mindCA small piece of fish each day may keep the heart doctor away. That’s the finding of a study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce of salt water fish per day compared to those who never ate fish.The Dutch research is one of three human studies that give strong scientific support to the long held belief that eating fish can provide health benefits, particularly to the heart.Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year. But previous research has shown that the level of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption averages more than 3 ounces.For 20 years, the Dutch stu dy followed 852 middle-aged men, 20 percent of whom ate no fish. At the start of the study, average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish than fatty fish.During the next two decades, 78 of the men died from heart disease. The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos.This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol(胆固醇)levels.28. In which section of a newspaper can we read this passage?A. AdsB. MoviesC. BriefsD. Health and Diet29. The passage is mainly about _________.A. the high incidence of heart disease in some countriesB. the changes in people’s dietC. the effect of fish eating on people’s healthD. the daily fish consumption of people in different cultures30. We can infer from the passage that there are fewer heart disease deaths ________.A. in countries of the yellow-skin raceB. in highly-developed countriesC. in the countries with high consumption of fishD. in the countries with good production of fish31. The phrase “this relationship” in paragra ph 6 refers to the connection between ____and the level of heart disease.A. the amount of fish eatenB. regular fish-eatingC. the kind of fish eatenD. people of different areasDA chemical important of brain development may play a role in explaining why some people are genetically (由基因决定地) likely to suffer from anxiety and could lead to new treatments, U.S. researchers said.They said highly anxious rats which were kept had very low levels of a brain chemical called fibroblast growth factor 2 or FGF2, compared with rats that were more relaxed. But when they improved the anxious rats’ living conditions — giving them new toys to explore and a bigger cage to live in — levels of this brain chemical increased and they became less anxious.“Th e levels of this brain chemical increased in response to the experiences that the rats were exposed to. It also decreased their anxiety”. Javier Perez of the University of Michigan said in a telephone interview. “It made them behave the same way as the rat s that were relaxed”, he said.In a former study of people who were severely depressed before they died, the team found the gene that makes FGF2 was producing very low levels of the growth factor, which is known primarily for organizing the brain during development and repairing it after injury.Perez thinks the brain chemical may be a marker for genetic vulnerability (脆弱性) to anxiety and depression. But it can also respond to changes in the environment in a positive way, possibly by preserving new brain cells.While both the calm and anxious rats produced the same number of new brain cells, these cells were less likely to survive in the high-anxiety rats, the team found. Giving the rats better living conditions or injecting them with FGF2 helped improve cell survival.“This discovery may pave the way for new, more specific treatments for anxiety that will not be based on sedation(药物镇静), but will instead fight the real cause of the disease,” Dr. Pier Vincenzo Piazza from France said in a statement.32. From the passage we can infer that with the levels of FGF2 decreasing, the rats will______ .A. die of anxiety soonB. suffer from a headacheC. become more anxiousD. become more relaxed33. The underlined word “it” in Paragraph 4 refers to .A. the brainB. the geneC. the growth factorD. the team34. What’s the main influence of the new discovery?A. Doctors won’t use any medicine to cure anxiety.B. Doctors may find new medicine for anxiety.C. Doctors will find the real cause of anxiety.D. Doctors may treat anxiety more efficiently.35. Which of the following would be the most suitable title for the passage?A. Anxious rats and relaxed ratsB. Anxiety — a serious mental diseaseC. Brain chemical may play key role in anxietyD.
