问题:共用题干 Memory Test1 "I am going to give you five techniques that will enable you to remember anything youneed to know at school,"promised lecturer Ian Robinson to a hundred schoolchildren.He slapped his hand down on the table."When I've finished in two hours' time,your work will be far more effective and productive.Anyone not interested, leave now."The entire room sat still.2 Robinson calls himself the Mind Magician(魔术师).He specializes in doing magic tricks that look totally impossible,and then he reveals that they involve nothing more mysteriousthan good old-fashioned trickery(骗术)."I have always been interested in tricks involving memory-being able to reel off(一口气说出)the order of cards in a pack, that sort of thing," he explains.3 Robinson was already lecturing to schools on his magic techniques when it struck him that students might find memory techniques even more valuable."It wasn't a difficult area to move into,as the stuff's all there in books."So he summarized everything to make a two-hour lecture about five techniques.4 "You want to learn a list of a hundred things?A thousand?No problem,"saysRobinson.The scandal is that every child is not taught the techniques from the beginning oftheir school life.The schoolchildren who were watching him thought it was brilliant."I wish I'd been told this earlier,"commented Mark,after Robinson had shown them how to construct"mental journeys".5 Essentially, you visualize(想象)a walk down a street, or a trip round a room,and pick the points where you will put the things you want to remember一the lamppost,the fruit bowl. Then in each location you put a visual representation of your list一phrasal verbs,historical dates,whatever一making them as strange as possible.It is that simple,and it works.6 The reaction of schools has been uniformly enthusiastic."The pupils benefited enormously from lan's presentation,"says Dr Johnston,head of the school where Robinson was speaking."Ideally we should run a regular class in memory techniques so pupils can pick it up gradually."Paragraph 4_______A:Good resultsB:An ancient skillC:Gaining attentionD:Memory tricksE:A lecture on memory techniquesF:Ways to improve memory
问题:共用题干 第一篇Approaches to Understanding IntelligencesIt pays to be smart,but we are not all smart in the same way.You may be a talented musician,but you might not be a good reader.Each of us is different.Psychologists disagree about what is intelligence and what are talents or personal abilities.Psychologists have two different views on intelligence.Some believe there is one general intelligence.Others believe there are many different intelligences.Some psychologists say there is one type of intelligence that can be measured with IQ tests.These psychologists support their view with research that concludes that people who do well on one kind of test for mental ability do well on other tests.They do well on tests using words,numbers,or pictures.They do well on individual or group tests,and written or oral tests.Those who do poorly on one test,do the same on all tests.Studies of the brain show that there is a biological basis for general intelligence.The brains of intelligent people use less energy during problem solving.The brain waves of people with higher intelligence show a quicker reaction.Some researchers conclude that differences in intelligence result from differences in the speed and effectiveness of information processing by the brain.Howard Gardner,a psychologist at the Harvard School of Education,has four children.He believes thai all children are different and shouldn't be tested by one intelligence test.Although Gardner believes general intelligence exists,he doesn't think it tells much about the talents of a person outside of formal schooling.He thinks that the human mind has different intelligences.These intelligences allow us to solve the kinds of problems we are presented with in life.Each of us has different abilities within these intelligences.Gardner believes that the purpose of school should be to encourage development of all of our intelligences.Gardner says that his theory is based on biology.For example,when one part of the brain is injured,other parts of the brain still work.People who cannot talk because of brain damage can still sing.So,there is not just one intelligence to lose.Gardner has identified 8 different kinds of intelligence:linguistic,mathematical,spatial,musical, interpersonal, intrapersonal, body-kinesthetic(身体动觉的),and naturalistic.According to Gardner,schools should______.A:promote development of all intelligencesB:test students'IQsC:train students who do poorly on testsD:focus on finding the most intelligent students

问题:共用题干 第一篇What Does GMO Free Mean?Genetically modified organisms(GMOs)in food are concern for a number of consumers who are worried about the impact that GMOs may have on their health.As a result,many companies in the late 1990s began to apply the GMO free label,indicating that their food does not contain genetically modified organisms.A number of nations legislate labeling,and in Europe,food must be labeled to indicate whether or not it contains GMOs.In the United States,however,GMO free labeling is purely voluntary and not regulated by any governmental body or organization.Since it is not regulated,there has been some question about the validity of the GMO free label in the US.A number of organizations have pressured the Food and Drug Administration(FDA),as well as the United States Department of Agriculture(USDA),to enact legislation governing food labeling in regards to GMOs.Many food activists want a label that is standardized,so that consumers who are concerned about this issue can be assured about the GMO content of products they purchase.Most US consumers have foods containing GMOs in their home.The majority of corn and soybeans grown in the US have been modified,as have several other crops.Some research indicates that many processed foods contain GMO ingredients,so for consumers who are concerned about this issue,GMO free labeling would be helpful.For consumers who want to eat natural,organic foods,knowing that the products they buy are GMO free is often very important. Although there is no federal labeling program in the US,some organic farmers and natural food producers have chosen to start their own certification programs.Getting certified through such programs can be very difficult,but many producers believe consumers will be willing to pay extra for the verification.The harmful nature of GMOs has been questioned,especially by commercial agriculture producers and seed providers.No scientific evidence has been found to suggest that genetic modification of crops is harmful to humans. Some consumers feel that it is important to be able to make conscious choices about what they eat,however,and want the ability to choose GMO free foods if they so desire.Some studies suggest that GMOs may be harmful to agriculture,with cloned genetically modified species harming overall biological diversity and modified genes finding their way into wild plants and non-modified crops.This is especially true in the case of corn,where GMO contamination became a major issue in the 1990s.Other research,however,indicates that genetically modified crops can be of benefit to the environment. Plants designed to be resistant to herbicides(除草剂)and pesticides (杀虫剂),for example,have been seen to reduce the amount of these chemicals used by farmers on both GM and non-modified crops.A number of organizations in America have pressured the Food and Drug Administration(FDA) to______.A: ban foods containing GMOsB:punish commercial agriculture producers and seed providersC:enact legislation governing food labeling in regards to GMOsD:abolish legislation governing food labeling in regards to GMOs

问题:共用题干 Wide World of RobotsEngineers who build and program robots have fascinating jobs. These researchers tinker(修补)with ma- chines in the lab and write computer software to control these devices."They're the best toys out there," says Howie Choset at Carnegie Mellon University in Pittsburgh.Choset is a roboticist,a person who designs, builds or programs robots.When Choset was a kid,he was interested in anything that moved一cars,trains,animals.He put motors on Tinkertoy cars to make them move.Later,in high school,he built mobile robots similar to small cars,Hoping to continue working on robots,he studied computer science in college.But when he got to graduate school at the California Institute of Technology in Pasadena,Choset’。labmates were working on something even cooler than remotely controlled cars:robotic snakes.Some robots can move only forward, hackward, left and right. But snakes can twist(扭曲)in many directions and travel over a lot of different types of terrain(地形)."Snakes are far more interesting than the cars,"Choset concluded.After he started working at Carnegie Mellon,Choset and his colleagues there began developing their own snake robots.Choset's team programmed robots to perform the same movements as real snakes,such as sliding and inching forward.The robot、also moved in ways that snakes usually don't,such as rolling. Choset’s snake robots could crawl(爬行)through the grass,swini in a pond and even climb a flagpole.But Choset wondered if his snakes might be useful for medicine as well.For some heart surgeries,the doctor has to open a patient's chest,cutting through the breastbone.Recovering from these surgeries can be very painful.What if the doctor could perform the operation by instead making a small hole in the body and sending in a thin robotic snake?Choset teamed up with Marco Zenati,a heart surgeon now at Harvard Medical School,to investigate theidea.Zenati practiced using the robot on a plastic model of the chest and they tested the robot in pigs. A company caikd Medrobotics in Boston is now adapting the technology for g urgerie9 on people-Even after 15 years of working with his team’s creations,"I still don't get bored of watching the motionof my robots,"Clioset says.Choset began to build robots in high school.A:RightB:WrongC:Not mentioned

问题:共用题干 Good Way to Exercise:JoggingJogging has become the most popular individual sport in America. Many theories,even some mystical ones,have been advanced to explain the popularity of jogging. The plain truth is that jogging is a cheap,quick and efficient way to maintain(or achieve)physical fitness.The most useful sort of exercise is exercise that develops the heart,lungs,and circulatory systems.If these systems are fit,the body is ready for almost any sport and for almost any sudden demand made by work or emergencies.One can train more specifically,as by developing strength for weight lifting or the ability to run straight ahead for short distances with great power in football,but running trains your heart and lungs to deliver oxygen more efficiently to all parts of your body.It is worth noting that this sort of exercise is the only kind that can reduce heart disease,the number one cause of death in America.Only one sort of equipment is needed一a good pair of shoes.Physicians advise beginning joggers not to run in a pair of tennis or gym shoes.Many designs have been made in only the last several years that make a pair of excellent running shoes in dispensable if a runner wishes to develop as quickly as possible,with as little chance of injury as possible.A pair of good running shoes will have a soft pad for absorbing shock,as well as a slightly built-up heel that will give the knee and ankle more stability.A wise investment in good shoes will prevent the foot,ankle and knee injuries and will also enable the wearer to run on paved or soft surfaces.No other special equipment is needed and you can jog in any clothing you desire.Many joggers wear expensive,flashy and warm suits,but just as many wear a simple pair of gym shoes and T-shirt.In fact,many people just jog in last year's clothes.In cold weather,several layers of clothing are better than one heavy sweater or coat. If joggers are wearing several layers of clothing,they can add or subtract layers as conditions change.It takes surprisingly little time to develop the ability to run.The American Jogging Association has a twelve-week program designed to move from a fifteen-minute walk(which almost anyone can manage who is in reasonable health)to a thirty-minute run.A measure of common sense,a physical examination.and a planned schedule are all it takes.Jogging is very popular in China among old men.A:Right B:WrongC:Not mentioned
问题:共用题干 Old Man Myths and Realities1.When does a middle-aged man become an old man?Officially,of course,it is when we reach retirement age. But, as we all know, this is a fairly blunt(生硬的)method of decision making. As life expectancy(寿命)increases,retirement planning needs to be changed. This is because being an old man today is very different from what it was a generation or so ago.2.Sixty-five is the new middle-aged man. These days people are talking about the young-old, that is ages 70-75,and those over 75 as the old-old. The young-old frequently continue in good health and maintain strong links with friends and family.The old-old have a much higher chance of poor health and social isolation.3.Although men are living longer,there are still more old women than old men.This fact alone should arouse interest as to why. Relatively little is actually known about why this is the case or about the experiences of the old man.Sure,we are aware that the old man experiences anxiety,financial problems,loneliness,etc.,but that is really about all we know.4.It is usually believed that the old man often complains about their health.In fact,most old man think their health is good even though most are diagnosed with at least one chronic illness.The physical health of the old man is strongly affected by their health behavior when they were younger.Paragraph 3______A:New Definitions of the Old ManB:Changing Concept of the Old ManC:Health of the Old ManD:Happy Old Man and Sad Old ManE:Limited Knowledge of the Old Man's Experiences F: Contempt for the Old Man

问题:共用题干 Learn about Light1 .Ancient civilizations were amazed by the existence of light for thousands of years. The Greek philosophers believed that light was made up of countless,tiny particles that enter the human eye and create what we call vision. However,Empedocles and a Dutch scientist named Christian Huygens believed that light was like a wave. According to them,light spread out and travelled like a straight line. This theory was accepted during the 19th century.2 .In 1905,Albert Einstein published a research paper in which he explained what is re-ferred to as the photoelectric effect. This theory explains that particles make up light.The particles Einstein was referring to are weightless bundles(束)of electromagnetic(电磁)energy called photons(光子).Today,scientists agree that light has a dual(二重)nature一it is part particle and part wave. It is a form of energy that allows us to see things around us.3 .Things that give off light are known as sources of light. During the day,the primary source of light is the sun. Other sources of light include stars,flames,flashlights,street lamps and glowing gases in glass tube.4 .When we draw the way light travels we always use straight lines. This is because nor-mally light rays travel in a straight line. However,there are some instances that can change the path and even the nature of light. They are reflection,absorption,interference(干扰), etc.5 .Physicists have attempted to measure the speed of light since the early times. In 1849, Hippolyte Fizeau conducted an experiment by directing a beam of light to a mirror located kilometers away and placed a rotating cogwheel(旋转齿轮)between the beam and the mirror. From the rate of rotation of the wheel,number of wheel's teeth and distance of the mirror,he was able to calculate that the speed of light is 313 million meters per second. In a vacuum(真空),however,the speed of light is 299,792,458 meters per second. This is about a million times faster than the speed of an airplane.Some instances such as reflection and absorption can change______.A: sources of lightB: the speed of lightC: the path of lightD: a straight lineE: a beam of lightF: a form of energy

问题:共用题干 When Our Eyes Serve Our StomachOur senses aren't just delivering a strict view of what's going on in the world;they're af-fected by what's going on in our heads. A new study finds that hungry people see food-related words more clearly than people who'ye just eaten.Psychologists have known for decades that what's going on,inside our head affects our senses. For example,poorer children think coins are larger than they are,and hungry people think pictures of food are brighter. Remi Radel of University of Nice Sophia-Antipolis,France,wanted to investi-gate how this happens. Does it happen right away as the brain receives signals from the eyes or a lit-tle later as the brain's high-level thinking processes get involved.Radel recruited 42 students with a normal body mass index. On the day of his or her test,each student was told to arrive at the lab at noon after three or four hours of not eating. Then they were told there was a delay. Some were told to come back in 10 minutes;others were given an hour to get lunch first. So half the students were hungry when they did the ex-periment and the other half had just eaten.For the experiment,the participant looked at a computer screen. One by one,80 words flashed on the screen for about 1/300th of a second each. They flashed at so small a size thatthe students could only consciously perceive. A quarter of the words were food-related. After each word,each person was asked how bright the word was and asked to choose which of two words they'd seen一a food-related word like cake or a neutral word like boat. Each word ap-peared too briefly for the participant to really read it.Hungry people saw the food-related words as brighter and were better at identifying food-related words. Because the word appeared too quickly for them to be reliably seen,this means that the difference is in perception,not in thinking processes,Radel says.“This is something great to me. Humans can really perceive what they need or what they strive for. From the experiment,I know that our brain can really be at the disposal of our mo-tives and needs,”Radel says.There was a delay in Radel's experiment because_______.A: he needed more students to joinB: he didn't prepare enough food for the 42 studentsC: he wanted two groups of participants,hungry and non-hungryD: he didn't want to have the experiment at noon
问题:共用题干 The iPad1 The iPad is a tablet computer(平板电脑)designed and developed by Apple. It is par-ticularly marketed as a platform for audio and visual media such as books,periodicals(期刊),movies,music,and games,as well as web content. At about 1 .5 pounds(680 grams), its size and weight are between those of most contemporary smartphones and laptop comput-ers.Apple released the iPad in April 2010,and sold 3 million of the devices in 80 days.2 The iPad runs the same operating system as iPod Touch and iPhone. It can run its own applications as well as ones developed for iPhone. Without modification,it will only run pro-grams approved by Apple and distributed via its online store.3 Like iPhone and iPod Touch,the iPad is controlled by a multitouch display一a break from most previous tablet computers, which uses a pressure-triggered stylus(触控笔).The iPad uses a Wi-Fi data connection to browse(浏览)the Internet, load and stream media, and install software. Some models also have a 3G wireless data connection which can connect to GSM 3G data networks. The devices is managed and synchronized(同步)by iTunes on a per-sonal computer via USB cable.4 An iPad has different features and applications one can use to execute different and in-teresting things. There are lots of iPad applications that the owner can use to enhance the way they communicate. Some of these are how to use social networking sites and other online options.One of the most common uses is for e-mail services. iPad applications like Markdown Mail allow the adoption of specific and particular options. They enable the owner to personal-ize their email accounts.5 While the iPad is mostly used by consumers it also has been taken up by business us-ers. Some companies are adopting iPads in their business offices by distributing or making available iPads to employees.Examples of uses in the workplace include lawyers responding to clients,medical professionals accessing health records during patient exams,and manag-ers approving employee requests.A survey by Frost Sullivan shows that iPad usage in work-places is linked to the goals of increased employees productivity,reduced paperwork,and in-creased revenue.Paragraph 3______A: Online StoresB: Differences from iPhoneC: Display and Data ConnectionD: Business UsageE: Features and ApplicationsF: Operating System
