  Mad Scientist Stereotype Outdated

  Do people still imagine a physicist as a bearded man in glasses or has the image of the madscientist changed? The Institute of Physics set out to find out whether the stereotype of a physics"boffin" (科學(xué)家) still exists by conducting a survey on shoppers in London. The peoplewere asked to identify the physicist from a photograph of a line-up of possible suspects.98percent of those asked got it wrong. The majority of people picked a white male of around 60,wearing glasses and with a white beard.

  While this stereotype may have been the image of all average physicist fifty years ago, thereality is now very different since 1960 the number of young women entering physics hasdoubled and the average age of a physicist is now 31.

  The stereotype of the absent-minded scientist has lasted a long time because the media andHollywood help promote the image of men in white lab coats with glasses sitting by blackboardsfull of equations (等式) or working with fizzing (嘶嘶響) test tubes. These stereotypes arereally damaging to society. Very good school children are put off studying science because theydon't see people like themselves on television or in magazines doing science. They simply don'trelate to the media's image of the mad scientist.

  This is one reason why fewer young people are choosing to do science at university. If wewant to encourage more young people to study science subjects, we need to change this imageof the scientist and make science careers more attractive. But we must also develop children'sinterest in science.

  In an attempt to change this negative image, an increasing number of science festivals arebeing organized. Thousands of people from secondary schools are also encouraged to take partin the international wide science competitions of which the most popular are the national ScienceOlympiads. Winning national teams then get the opportunity to take part in the International Science Olympiads which are held in a different county every year. These events are allinteresting for the young people who take part but they only involve a small proportion of

  students who are already interested in science. It seems that there is a long way to go beforescience becomes attractive as subjects like computer studies or fashion and design.

  Most people have similar ideas of what a physicist looks like.

  A.Right B.Wrong C.Not mentioned

  Cloning (克隆) : Future Perfect?

  1. A clone is all exact copy of a plant or animal produced from any one cell. Since Scottishscientists reported that they had managed to clone a sheep named Dolly in 1997, researchinto cloning has grown rapidly. In May 1998, scientists in Massachusetts managed to createtwo identical calves (牛犢) using cloning technology. A mouse has also been clonedsuccessfully, But the debate over cloning humans really started when Chicago physicistRichard Seed made a surprising announcement: "We will have managed to Clone a humanbeing within the next two years," he told the world.

  2. Seed's announcement provoked a lot of media attention, most of it negative. In Europe,nineteen nations have already signed an agreement banning human cloning and in the US thePresident announceD. "We will be introducing a law to ban all human cloning and manystates in the US will have passed anti-cloning laws by the end of the year. "

  3, Many researchers are not so negative about cloning, They are worded that laws banninghuman cloning will threaten important research. In March, The New England Journal ofMedicine called any plan to ban research on cloning humans seriously mistaken. Manyresearchers also believe that in spite of attempts to ban it, human cloning will have beconieroutine by 2010 because it is impossible to stop the progress of science.

  4. Is there reason to fear that cloning will lead to a nightmare world? The public has beenbombarded (轟炸) with newspaper articles, television shows and films, as well ascartoons. Such information is often misleading, and makes people wonder what on earth thescientists will be doing next.

  Within the next five to ten years scientists will probably have found a way of cloninghumans. It could be that pretty soon we will be able to choose the person that we want ourchild to look like. But how would it feel to be a clone among hundreds, the anti-clonersask,. Pretty cool, answer the pro-cloners (贊成克隆的人).

  More Than a Ride to School

  The National Education Association claims. " The school bus is a mirror of thecommunity. " They further add that, unfortunately, what appears on the exterior does not alwaysreflect the reality of a chosen community. They are fight -- sometimes it reflects more! Just askLiesl Denson. Riding the school bus has been more than a ride to school for Liesl.

  Bruce Hardy, school bus driver for Althouse BUS Company has been Liesl's bus driversince kindergarten. Last year when Liesl's family moved to Parkesburg, knowing her bus wentby her new residence. She requested to ride the same bus.

  This year Liesl is a senior and will enjoy her last year riding the bus. She says, " It's beena great ride so far! My bus driver is so cool and has always been a good friend and a goodlistener. Sometimes when you're a child adults do not think that what you have to say isimportant. Mr. Hardy always listens to what you have to say and makes you feel important. "Her friends Ashley Bafista and Amanda Wolfe agree.

  Bruce Hardy has been making Octorara students feel special since 1975. This year he willcelebrate 30 years working for Althouse Bus Company, Larry Althouse, president of thecompany, acknowledges Bruce Hardy's outstanding record: "You do not come by employeeslike Bruce these days. He has never missed a day of work and has a perfect driving record. Hewas recognized in 2000 by the Pennsylvania School Bus Association for driving 350,000accident free miles. Hardy's reputation is made further evident through the relationships he hasmade with the students that ride his bus. "

  Althouse further adds, "Althouse Bus Company was established 70 years ago and has beenproviding quality transportation ever since. My grandfather started the business with one bus.Althouse Bus Company is delighted to have the opportunity to bring distinctive and safe serviceto our local school and community and looks forward to continuing to provide quality service formany more years to come. "

  hree generations of business is not all the company has enjoyed. Thanks to drivers likeBruce Hardy, they have been building relationships through generations, Liesl's mother Carolalso enjoys fond memories of riding Bruce Hardy's bus to the Octorara School District.

  A Phone That Knows You're Busy

  It's a modem problem: you're too busy to be disturbed by incessant (連續(xù)不斷的) phonecalls so you turn your cell phone off. But if you don't remember to turn it back on when you'reless busy. You could miss some important calls if only the phone knew when it was wise tointerrupt you, you wouldn't have to tum it off at all. InsteaD. it could let calls through whenyou are not too busy.

  A bunch of behavior sensors (傳感器) and a clever piece of software could do just that,by analyzing your behavior to determine if it's a good time to interrupt you. If built into aphone, the system may decide you're too busy and ask the caller to leave a message or ring backlater.

  James Fogarty and Scott Hudson at Carnegie Mellon University in Pennsylvania based theirsystem oil tiny microphones, cameras and touch sensors that reveal body language and activity.First they had to study different behaviors to find out which ones strongly predict whether yourmind is interrupted.

  The potential "busyness" signals they focused on included whether the office doors wereleft open or closeD. the time of day, if other people were with the person in question, howclose they were to each other, and whether or not the computer was in use.

  The sensors monitored these and many other factors while four subjects were at work. Atrandom intervals, the subjects rated how interrupdble they were on a scale ranging from "highlyinterruptible" to "highly not-interruptible". Their ratings were then correlated with the variousbehaviors . "It is a shotgun (隨意的) approach: we used all the indicators we could think ofand then let statistics find out which were important, " says Hudson.

  The model showed that using the keyboarD. and talking on a landline or to someone else in the office correlated most strongly with how interruptible the subjects judged themselves to be.Interestingly, the computer was actually better than people at predicting when someone was toobusy to be interrupted. The computer got it right 82 per cent of the time, humans 77 per cent.Fogarty speculates that this might be because people doing the interrupting are inevitably biasedtowards delivering their message, whereas computers don't care.

  The first application for Hudson and Fogarty's system is likely to be in an instant messagingsystem, followed by office phones and cellphones. "There is no technological roadblock ( 障礙) to it being deployed in a couple of years, " says Hudson.

  A big problem facing people today is that

  A.they must tolerate phone disturbances or miss important calls

  B.they must turn off their phones to keep their homes quiet

  C.they have to switch from a desktop phone to a cell phone

  D.they are too busy to make phone calls

  37、 The behavior sensor and software system built in a phone

  A.could help store messages

  B.could send messages instantly

  C.could tell when it is wise to interrupt you

  D.could identify important phone calls

  38、 Scientists at Carnegie Menon University tried to find out

  A.why office doors were often left open

  B.when it was a good time to turn off the computer

  C.what questions office workers were bothered with

  D.which behaviors could tell whether a person was busy

  39、 During the experiment, the subjects were asked

  A.to control the sensors and the camera

  B.to rate the degrees to which they could be interrupted

  C.to compare their behaviors with others'

  D.to analyze all the indicators of interruption

  40、 The computer performed better than people in the study because

  A.the computer worked harder

  B.the computer was not busy

  C.people tended to be biased

  D.people were not good at statistics

  The Exploding Lakes of Cameroon

  What comes to mind when you think of a lake? You probably imagine a pretty scene withblue water, birds, and fish. For the people in the northwestern Cameroon, however, the image is very different. For them, lakes may mean terrible disasters. In 1984, poisonous gasesexploded out of Lake Monoun and came down into the nearby villages, killing thirty-sevenpeople. Two years later, Lake Nyos erupted. A cloud of gases rolled down the hills and into thevalleys and killed 1,700 people.

  Lake Nyos and Lake Monoun are crater (火山口) lakes They were formed when watercollected in the craters of old volcanoes. The volcanoes under Lake Nyos and Lake Monoun arenot active anymore. However, poisonous gases from the center of the earth continue to flow upthrough cracks in the bottom of the lake. This is normal in a crater lake. In most crater lakes,these gases are released often because the water "turns over" regularly. That is, the water fromthe bottom of the lake rises and mixes with the water at the top, allowing the gases to escapeslowly.

  However, in Lakes Nyos and Monoun, there is no regular turning over. No one knows thereason for this fact, but as a result, these lakes have more gases tapped at the bottom than othercrater lakes. In fact, scientists who have studied Lakes Nyos and Monoun have found 16,000times more gases. When a strong winD. cool weather a storm, or a landslide (滑坡) causesthe water to turn over suddenly, the gases escape in a violent explosion.

  In the past, no one knew when the gases might explode, so there was no way for thevillagers to escape disaster. Now scientists from the United States, France, and Cameroon havefound a way to reduce the gas pressure at the bottom of Lake Nyos. They stood a 672-footplastic pipe in the middle of the lake, with one end of the pipe near the bottom and the otherend in the air. Near the top of the pipe, the team putseveral holes that could be opened orclosed by a computer. Now, when the gas pressure gets too high, the holes are opened andsome of the gas-filled water shoots up through the pipe into the air like a fountain. With lesspressure, a disastrous explosion is much less likely. However, the scientists are not sure thatone pipe will be enough to prevent explosions. They hope to put in others soon and they plan toinstall a similar pipe and a computer system at Lake Monoun as well.

  To protect people nearby until all of the pipes are in place, the scientists have installedearly warning systems at both lakes. If the gas pressure rises to a dangerous level, computerswill set off loud sirens (勁爆) and bright lights to warn the people in the villages. That way,they will have time to escape from the dangerous gases.

  What will happen when Lake Nyos and Lake Monoun explode_________?

  A.Water will flow down the hills

  B.Poisonous gases will be released suddenly.

  C.A strong wind will rise from the lakes

  D.The volcanoes will come to life.

  42、 Which of the following statements about Lake Nyos and Lake Monoun is true_________?

  A.They were formed in 1984.

  B.They are at the top of two active volcanoes.

  C.They are not like most other crater lakes.

  D.Water in them turns over regularly.

  43、 Lake Nyos and Lake Monoun explode because_________

  A.the gases rise to the top and mix with air

  B.people from the villages turn over the water

  C.scientists have put in a computer system

  D.they have more gases trapped at the bottom than other Crater lakes

  44、 A team of scientists has_________

  A.erected a pressure-releasing pipe in the lake

  B.identified the gases at the bottom of the lake

  C.built a beautiful fountain near the lakes

  D.removed all dangerous gases from the lakes

  45、What do we learn from the last paragraph_________?

  A.Scientists are planning to install pipes in all crater lakes.

  B.Scientists still do not know how to prevent gas explosions.

  C.Explosion disasters could be avoided in the future.

  D.Warning systems have been set up in the villages nearby.

  Every Dog ttas Its Say

  Kimiko FukudA. a Japanese gift, always wondered what her dog was trying to say.Whenever she put on makeup, it would pull at her sleeve. (46) _________ When the dog barks,she glances at a small electronic gadget (裝置). The following "human" translation appearson its screen: "Please take me with you. " "I realized that's how he was feeling. " saidFukuda.

  The gadget is called Bowlingual, and it translates dog barks into feelings. People laughedwhen the Japanese toymaker Takara Company made the world's first d0g-human translationmachine in 2002. But 300,000 Japanese dog owners bought it. (47) _________ "Nobody else hadthought about it," said Masahiko KajitA. who works for Takara , "We spend so much timegaining dogs to understand our orders; what would it be like if we could understand dogs?"Bowlingual has two parts. (48)_________ The translation is done in the gadget using a database(資料庫(kù)) containing every kind of bark.

  Based on animal behavior research, these noises are divided into six categories:happiness, sadness, frustration, anger, declaration and desire. (49)_________In this way, thedatabase scientifically matches a bark to an emotion, which is then translated into one of 200phrases. When a visitor went to Fukuda's house recently, the dog barked a loud "bow wow".

  This translated as "Don't come this way"(50)_________The product will be available in US pet stores this summer for about US $120 It can store up to 100 barks, even recording the dog's emotions when the owner is away

  Earth's Inner Core

  Scientists have long struggled to understand what lies at the planet's center, Direct observation of its center is impossible, so researchers must (51)_________ to other evidence.

  In 1889, a German scientist detected a severe earthquake in Japan. Geophysicistsconcluded that shock waves (52) _________ jolts (晃動(dòng)) from one side of Earth through the centerto the other side. Then in 1936, Danish geophysicist Inge Lehmann studied the waves (53)_________to determine that within Earth's core of molten (熔化了的) iron lies a solid inner core-but(54) _________that core was made of eluded (難倒) her. Other geophysicists quicklydetermined that Lehmann's inner core was composed mostly(55)_________iron. Since then,Lehmann's discovery has (56) _________conventional Earth science.

  But now scientists are challenging traditional theory with new and radical (57)_________. Forexample, Earth's center could actually contain an "inner core within the inner core, claim Ishiiand colleague Adam Dziewonski. Analyzing hundreds of thousands of earthquake wave(58)_________, they maintain that the inner core has at its heart a tiny, even more solid sphere(球體) . This sphere "may be the oldest fossil (59)_________ from the formation of Earth," saysDziewonski.

  Dziewonski and Ishii speculate that shortly (60)_________ earth formed around 4.8billionyears ago, a giant asteroid (小行星) smashed into the young planet and nearly melted it. ButEarth's center didn't quite melt; it (61) _________ mass as the planet cooled. The core within acore may be the kernel (核心) that endured. "Its presence could change our basic ideas about the(62) _________ of the planet, " Dziewonski says idea is tame (溫和的) compared to the(63)_________ theories of independent geophysicist J. Marvin Herndon. Earth's inner core ismade not of iron, he claims but a(64)_________ of nickel and silicon Hemdon has a trulyrevolutionary notion: Within the nickel silicide (硅化物) inner core is also an "inner" innercore an 8 km -- wide ball of the element uranium. Uranium is radioactive. Hemdon thinksthe uranium releases heat energy as its atoms(65)_________ fission-split and crash into another in achain reaction. In other words, we may live on top of a gigantiC. "natural" nuclear powerplant.
