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

问题：共用题干 第三篇Almost Human?Scientists are racing to build the world's first thinking robot.This is not science fiction: some say they will have made it by the year 2020.Carol Packer reports.Machines that walk,speak and feel are no longer science fiction.Kismet is the nameof an android（机器人）which scientists have built at the Massachusetts Institute of Technology(MIT).Kismet is different from the traditional robot because it can show human emotions.Its eyes,ears and lips move to show when it feels happy,sad or bored. Kismet is one of the first of a new generation of androids一robots that look like human beings一which can imitate human feelings.Cog,another android invented by the MIT, imitates the action of a mother. However,scientists admit that so far Cog has the mental ability of a two-year-old.The optimists（乐观主义者）say that by the year 2020 we will have created humanoids （机器人）with brains similar to those of an adult human being. These robots will be designed to look like people to make them more attractive and easier to sell to the public. What kind of jobs will they do?In the future,robots like Robonaut,a humanoid invented by NASA,will be doing dangerous jobs,like repairing space stations.They wi}{also be doing more and more of the household work for us.In Japan,scientists are designing androids that will entertain us by dancing and playing the piano.Some people worry about what the future holds:will robots become monsters（怪物）? Will people themselves become increasingly like robots?Experts predict that more and more people will be wearing micro-computers,connected to the Internet,in the future.People will have micro-chips in various parts of their body,which will connect them to a wide variety of gadgets（小装置）.Perhaps we should not exaggerate（夸大）the importance of technology,but one wonders whether,in years to come,we will still be falling in love, and whether we will still feel pain.Who knows?Kismet is different from traditional robots becauseA:it thinks for itself.

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 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 The first navigational lights in the New World were probably lanterns hung at harbor en-trances .The first lighthouse was put up by the Massachusetts Bay Colony in 1716 on Little Brewster Island at the entrance to Boston Harbor. Paid for and maintained by“light dues”levied（征收）on ships,the original beacon was blown up in 1776.Until then there were only a dozen or so true lighthouses in the colonies .Little over a century later,there were 700 lighthouses.The first eight lighthouses erected on the West Coast in the l850s featured the same basic New England design:a Cape Cod dwelling with the tower rising from the center or standing close by .In New England and elsewhere,though,lighthouses reflected a variety of architectural styles.Since most stations in the Northeast were set up on rocky eminences（高处）,enormous towers were not the rule .Some were made of stone and brick,others of wood or metal. Some stood onpilings or stilts;some were fastened to rock with iron rods.Farther south,from Maryland through the Florida Keys,the coast was low and sandy.It was often necessary to build tall towers there—massive structures like the majestic lighthouse in Cape Hatteras,North Carolina,which was lit in 1870.190 feet high,it is the tallest brick lighthouse in the country.Not withstanding differences in construction appearance,most lighthouses in America shared several features:a light,living quarters,and sometimes a bell(or,later,a foghorn).They also had something else in common:a keeper and usually the keeper's family.The keeper's essential task was trimming the lantern wick（灯芯）in order to maintain a steady,bright flame. The earli-est keepers came from every walk of life,they were seamen,farmers,mechanics,rough mill hands and appointments were often handed out by local customs commissioners as political plums. After the administration of lighthouse was taken over in 1852 by the United States Lighthouse Board,and agency of the Treasury Department,the keeper corps gradually became highly profes- sional.It can be inferred from the passage that lighthouses in the Northeast did NOT need high tow-ers because______.A: ships there had high mastsB: coastal waters were safeC: the coast was straight and unobstructedD: the lighthouses were built on high places
问题：共用题干 第三篇Technology Transfer in GermanyWhen it comes to translating basic research into industrial success,few nations can match Germany.Since the 1940s,the nation's vast industrial base has been fed with a constant stream of new ideas and expertise from science.And though German prosperity （繁荣）has faltered（衰退）over the past decade because of the huge cost of unifying east and west as well as the global economic decline , it still has an enviable（令人羡慕的）record for turning ideas into profit.Much of the reason for that success is the Fraunhofer Society,a network of research institutes that exists solely to solve industrial problems and create sought-after technologies. But today the Fraunhofer institutes have competition.Universities are taking an ever larger role in technology transfer,and technology parks are springing up all over.These efforts are being complemented by the federal programmes for pumping money into start-up companies.Such a strategy may sound like a recipe for economic success,but it is not without its critics.These people worry that favouring applied research will mean neglecting basicscience,eventually starving industry of fresh ideas.If every scientist starts thinking like an entrepreneur（企业家）,the argument goes , then the traditional principles of university research being curiosity-driven,free and widely available will suffer.Others claim that many of the programmes to promote technology transfer are a waste of money because half the small businesses that are promoted are bound to go bankrupt within a few years.While this debate continues,new ideas flow at a steady rate from Germany's research networks,which bear famous names such as Helmholtz,Max Planck and Leibniz.Yet it is the fourth network,the Fraunhofer Society,that plays the greatest role in technology transfer.Founded in 1949,the Fraunhofer Society is now Europe's largest organisation for applied technology,and has 59 institutes employing 12,000 people.It continues to grow. Last year,it swallowed up the Heinrich Hertz Institute for Communication Technology in Berlin.Today,there are even Fraunhofers in the U. S. and Asia.When was the Fraunhofer Society founded?A:In 1940. B:Last year.C:After the unification. D:In 1949.

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
