Cloning(克隆):Future Perfect?1 A clone is all exact copy of a plant or animal produced from any one cell. Since Scottish scientists reported that they had managed to clone a sheep named Dolly in 1997,research into cloning has grown rapidly.In May 1998,scientists in Massachusetts managed to create two identical calves(牛犊)using cloning technology.A mouse has also been cloned successfully,But the debate over cloning humans really started when Chicago physicist Richard Seed made a surprising announcement:“We will have managed to clone a human being 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 the President announced:”We will be introducing a law to ban all human cloning and many states 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 worried that laws banning human cloning will threaten important research.In March,The New England Journal of Medicine called any plan to ban research on cloning humans seriously mistaken.Many researchers also believe that in spite of attempts to ban it,humancloning will have become routine 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 been bombarded(轰炸)with newspaper articles,television shows and films,as well as cartoons.Such information is often misleading,and makes people wonder what on earth the scientists will be doing next.Within the next five to ten years scientists will probably have found a way of cloning humans. It could be that pretty soon we will be able to choose the person that we want our child to look like.But how would it feel to be a clone among hundreds,the anti-cloners ask.Pretty cool, answer the pr-cloners(赞成克隆的人).第4部分:阅读理解(第31~45题,每题3分,共45分)下面有3篇短文,每篇短文后有5道题,每道题后面有4个选项。

职称英语等级理工类(A级)试题考试试题答案及题解4第二篇A Phone That Knows You’re BusyIt’s a modern problem:you’re too busy to be disturbed by incessant(连续不断的)phone calls so you turn your cellphone off .But if you don’t remember to turn it back on when you’re less busy.you could miss some important calls if only the phone knew when it was wise to interrupt you,you wouldn’t have to turn it off at all. Instead,it could let calls through when you are not too busyA bunch of behavior sensors(传感器)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 a phone,the system may decide you’re too busy and ask the caller to leave a message or ring back later.James Fogarty and Scott Hudson at Camegie Mellon University in Pennsylvania based their system 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 stongly predict whether your mind is interrupted.The potential“busyness”signals they focused on included whether the office doors were left open or closed,the time of day,if other people were with the person in question,how close 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 . At random intervals,the subjects rated how interruptible they were on a scale ranging from“highly interruptible’’to“highly not—interruptible” . Their ratin gs were then correlated with the various behaviors . “It is a shotgun(随意的)approach:we used all the indicators we could think of and then let statistics find out which wereimportant,” 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 too busy 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 biased towards delivering their message,whereas computers don’t care.The first application for Hudson and Fogarty’s system is likely to be in an instant messaging system,followed by office phones and cellphones.“There is no technological roadblock(障碍) to it being deployed in a couple of years,” says Hudson36 A big problem facing people today is thatA 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 cellphone.D they are too busy to make phone calls.37 The behavior sensor and software system built in a phoneA could help store messages.B could send messages instantlyC could tell when it is wise to interrupt you.D could identify important phone calls.38 Scientists at Carnegie Menon University tried to find outA why office doors were often 1eft 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 busy39 During the experiment,the subjects were askedA 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 becauseA the computer worked harder.B the computer was not busyC people tended to be biased.D people were not good at statistics.。

Mad Scientist Stereotype OutdatedDo people still imagine a physicist as a bearded man in glasses or has the image of the mad scientist changed? The Institute of Physics set out to find out whether the stereotype of a physics‘boffin’(科学家)still exists by conducting a survey on shoppers in London.The people were asked to identify the physicist from a photograph of a line-up of possible suspects.98 percent of those asked got it wrong.The majority of people picked a white male of around 60,wearingglasses and with a white beard.While this stereotype may have been the image of all average physicist fifty years ago,the reality is now very different Since 1960 the number of young women entering physics has doubled 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 and Hollywood help promote the image of men in white lab coats with glasses sitting by blackboards full of equations(等式)or working with fizzing(嘶嘶响)test tubes.These stereotypes are really damaging to society.Very good school children are put off studying science because they don’t see people like themselves on television or in magazines doing science.They simply don’t relate 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 we want to encourage more young people to study science subjects,we need to change this image of the scientist and make science careers more attractive.But we must also develop children’s interest in science.In an attempt to change this negative image,an increasing number of science festivals are being organized.Thousands of people from secondary schools are also encouraged to take part in the internationwide science competitions of which the most popular are the national science Olympiads.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 all interesting 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 before science becomes attractive as subjects like computer studies or fashion and design.16 Most people have similar ideas of what a physicist looks like.A RightB WrongC Not mentioned17 The majority of physicists in Britain today are Cambridge graduatesA RightB WrongC Not mentioned18 The media and the cinema have played a role in promoting the image of the mad scientist.A RightB WrongC Not mentioned19 There will be more women scientists than men scientists in the futureA RightB WrongC Not mentioned20 More children will study science if it becomes more attractive.A RightB WrongC Not mentioned21 The image of the mad scientist is really encouraging to society.A RightB WrongC Not mentioned22 The International Science Olympiads are held once every two years.A RightB WrongC Not mentioned。

The most important of these engineers was Isambard Kingdom Brunel, whose work in shipping, bridge-building, and railway construction, to name just three fields, both challenged and motivated his colleagues. He was the driving force behind a number of the hugely ambitious projects, some of which resulted in works which are still in use today.The son of an engineer, Brunel apprenticed with his father at an early age on the building of the Thames Tunnel. At the age of just twenty, he became engineer in charge of the project. This impressive plan to bore under the Thames twice suffered two major disasters when the river broke through into the tunnel when the second breach(决口)ourredin 1872, Brunel was seriously injured during rescue operation and further work was halted.While recovering from his injuries, Brunel entered a design petition for a new bridge over the Avon Gorge near Clifton. The original judge of the petition was Thomas Telford, a leading civil engineer of his day, who rejected all entries to the petition in favor of his own design.After considerable scandal, a second contest was held and Brunel's design was aepted. For reasons of funding, however, exacerbated(加剧) by social unrest in Bristol, the project was abandoned in 1843 with only the towers pleted. After Brunel’s death, it was decided to begin work on it again, partly so that the bridge could form a fitting memorial to the great engineer. The entire structure was finally pleted in 1864. Today, the well-known Clifton Suspension Bridge is a symbol of Bristol, just as the Opera House is of Sydney. Originally intended only for horse-drawn traffic, thebridge now bears over four million motor vehicles a year.16.【题干】Brunel was an important airplane engineer in Britain during the Industrial Revolution.A.RightB.WrongC.Not mentioned17.【题干】Brunel was involved less in railway construction than in other engineering fields.A.RightB.WrongC.Not mentioned18.【题干】Brunel worked only on shipping, bridge-building and railway construction.A.RightB.WrongC.Not mentioned19.【题干】Brunel work was largely ignored by his colleagues.A.RightB.WrongC.Not mentioned20.【题干】Some projects Brunel contributed to arestill in use today.A.RightB.WrongC.Not mentioned21.【题干】Brunel became an apprentice with his father when he was very young.A.RightB.WrongC.Not mentioned22.【题干】The Thames Tunnel project was more difficult than any previous projects undertaken in Britain.A.RightB.WrongC.Not mentioned。

职称英语理工类A级考试真题及答案(部分)Small But WiseOn December 14, NASA1 blasted a small but mighty telescope into space. The telescope is called WISE and is about as wide around as a trashcan. Don’t let its small size fool you: WISE has a powerful digital camera, and it will be taking pictures of some the wildest objects2 in the known universe, including asteroids, faint stars, blazing galaxies3 and giant clouds of dust where planets and stars are born.“I’m very excited because we’re going to be s eeing parts of the universe that we haven’t seen before, “said Ned Wright, a scientist who directs the WISE project.Since arriving in space, the WISE telescope has been circling the Earth, held by gravity in a polar orbit4 (this means it crosses close to the north and south poles with each lap5). Its camera is pointed outward, away from the Earth, and WISE will snap a picture of a different part of the sky every 11 minutes. After six months it will have taken pictures across the entire sky.The pic tures taken by WISE won’t be like everyday digital photographs, however. WISE stands for “Wide-field Infrared Survey Explorer.” As its name suggests, the WISE camera takes pictures of features that give off infrared radiation6.Radiation is energy that travels as a wave. Visible light, including the familiar spectrum of light7 that becomes visible in a rainbow, is an example of radiation. When an ordinary digital camera takes a picture of a tree, for example, it receives the wavesof visible light that are reflected off the tree. When these waves enter the camera through the lens, they’re processed by the camera, which then puts the image together.Waves of infrared radiation are longer than waves of visible light, so ordinary digital cameras don’t s ee them, and neither do the eyes of human beings. Although invisible to the eye, longer infrared radiation can be detected as warmth by the skin.That’s a key idea to why WISE will be able to see things other telescopes can’t. Not everything in the universe shows up in visible light. Asteroids, for example, are giant rocks that float through space — but they absorb most of the light that reaches them. They don’t reflect light, so they’re difficult to see. But they do give off infrared radiation, so an infrared telescope like WISE will be able to produce images of them. During its mission WISE will take pictures of hundreds of thousands of asteroids.Brown dwarfs8 are another kind of deep-space object that will show up in WISE’s pictures. These object s are “failed” stars — which means they are not massive enough to jump start9 the same kind of reactions that power stars such as the sun. Instead, brown dwarfs simply shrink and cool down. They’re so dim that they’re almost impossible to see with visible light, but in the infrared spectrum they glow.词汇:trashcan / ‘traelig;,kaelig;n/n.垃圾箱infrared/’infr’red/ adj.红外线asteroid/’aelig;strid/ n.小行星dwarf/dw:f/ n. 矮星注释:1.NASA (美国国家航空航天局)是缩写词,全称是National Aeronautics and Space Administration。
2. the wildest objects :任何你能想象得到的天体。
