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-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's labmates were working on something even cooler than remotely controlled cars:robotic snakes.Some robots can move only forward, backward , 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'5 team programnied robots to perform the same movements as real snakes,such as sliding and inching forward.The robots also moved in ways that snakes usually don't,such as rolling.Choset's snake robots could crawl（爬行）through the grass ,swim 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 the idea. Zenati practiced using the robot on a plastic model of the chest and they tested the robot in pigs.A company called Medrobotics in Boston is now adapting the technology for surgeries 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,"Choset says. Choset's snake robots could make more movements than the ones others developed.A: RightB: WrongC: Not mentioned

Science and Truth“FINAGLE”（欺骗）is not a word that most people associate with science. One reason is that the image of the scientist is of one who always______ (51)data in an impartial（不偏不倚的）search for truth. In any debate______ ( 52 ) intelligence , schooling , energy—the phrase“science says”usually disarms opposition.But scientists have long acknowledged the existence of a“finagle factor”—a tendency by many scientists to give a helpful change to the data to______(53)desired results.The latest of the finagle factor in action comes from Stephen Jay Gould,a Harvard biologist,who has ______(54)the important 19th century work of Dr. Samuel George Morton.Morton was fa-mous in his time for analysing the brain______(55)of the skulls as a measure of intelligence.He concluded that whites had the largest brains,that the brains of Indians and blacks were smaller,and______(56),that whites constitute a superior race.Gould went back to Morton's original data and concluded that the______(57)were an example of the finagle at work .He found that Morton's“discovery”was made by leaving out embarrassing data,______(58)incorrect procedures,and changing his criteria-again,always in fayour of his argument. Morton has been thoroughly discredited by now and scientists do not believe that brain size reflects______(59).But Gould went on to say Morton's story is only an example of a common problem in ______(60)work .Some of the leading figures in science are______(61)to have used the finagle factor. Gould says that Isaac Newton fudged out（捏造）to support at least three central statements that he could not prove .And so______(62)Laudius Ptolemy,the Greek astronomer,whose master work,Almagest,summed up the case for a solar system that had the earth asits centre .Recent______(63)indicate that Ptolemy either faked some key data or resorted heavily to the finagle factor.All this is important because the finagle factor is still at work.For example,in the artificial sweetener controversy,it is______(64)that all the studies sponsored by the sugar industry find that the artificial sweetener is unsafe,______(65)all the studies sponsored by the diet food industry find nothing wrong with it.57._________A:. resultsB: experimentsC: ideasD: suggestions

The Gene IndustryMajor companies are already in pursuit of commercial applications of the new biology.They dream of placing enzymes（酶）in the automobile to monitor exhausts and send data on pollution to a microprocessor（微处理机）that will then adjust the engine. They speak of what the New YorkTimes calls “metal-hungry microbes（渴望吃金属的微生物）that might be used to mine valuable trace metals from ocean water”.They have already demanded and won the right to patent new lifeforms.Nervous critics,including many scientists,wony that there is corporate,national,intema- tional , and inter-scientific rivalry in the entire biotechnological（生物工艺学）field. They create images not of oii spills,but of“microbe spills”that could spread disease and destroy entire pop- ulations. The creation and accidental release of extremely poisonous microbes,however,is only one cause for alarm.Completely rational and respectable scientists are talking about possibilities that stagger the imagination.Should we breed people with cow-like stomachs so they can digest grass and hay,thereby relieving the food problem by modifying us to eat lower down on the food chain?Should we biologi- cally alter workers to fit the job requirement,for example,creating pilots with faster reaction times or assembly-line workers designed to do our monotonous work for us?Should we attempt to eliminate“inferior”people and breed a“super-race”?(Hitler tried this,but without the genetic weaponry that may soon issue from our laboratories.)Should we produce soldiers to do our fighting? Should we use genetic forecasting to pre-eliminate“unfit”babies?Should we grow reserve organs for ourselves,each of us having,as it were,a“savings bank”full of spare kidneys,livers or hands?Wild as these notions may sound,every one has its advocates(and opposers)in the scientific community as well as its striking commercial application.As two critics of genetic engineering,Jeremy Rifkin and Ted Howard,state in their book Who Should Play God?“Broad scale genetic engineering will probably be introduced to America much the same way as assembly lines,automobiles,vaccines,computers and all the other technologies.As each new genetic advance becomes commercially practical,a new consumer need will be exploited and a market for the new technology will be created.” Which of the following notions is NOT mentioned?A: Developing a“savings bank”of one's organs.B: Breeding soldiers for a war.C: Producing people with cow-like stomachs.D: Using genetic forecasting to cure diseases.

The first navigational lights in the New World were probably lanterns hung at harbor entrances.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 1850s 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 on pilings 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 theremassive 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 earliest 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 professional. It can be inferred from the passage that lighthouses in the Northeast did NOT need high towers because______.A: ships there had high mastsB: coastal waters were safeC: the coast was straight and unobstructedD: the lighthouses were built on high places
