共用题干Cell Phone Lets Your Secret OutYour cell phone holds secrets about you.Besides the names and _____________(51)that you've pro-grammed into it,traces of your DNA linger on the device,according to a new study.DNA is genetic material that______________(52)in every cell.Like your fingerprint,your DNA is uniqueto you一 _____________（53)you have an identical twin.Scientists today routinely analyze DNA in blood,saliva,or hair left _____________(54)at the scene of a crime.The results often help detectives identify_____________(55)and their victims.Your cell phone can reveal more about you _____________(56)you mightthink. Meghan J.McFadden,a scientist at McMaster University in Hamilton,Ontario,heard about a crime in which the suspect bled onto a cell phone and later dropped the______________(57).This made her wonder whether traces of DNA lingered on cell phones even when no blood was involved.______________(58)she and colleague Margaret Wallace of the City University of New York analyzed the flip-open phones of 10 volun- teers.They used swabs to collect______________(59)traces of the users from two parts of the phone:the outside,where the user holds it,and the______________(60),which is placed at the user's ear.The scientists scrubbed the phones using a solution made mostly______________(61)alcohol.The aim of washing was to remove all detectable traces of DNA.The owners got their phones______________(62)for another week.Then the researchers collected the phones and repeated the swabbing of each phone once more.The scientists discovered DNA that _____________(63)to the phone's speaker on each of the phones.Better samples were collected from the outside of each phone,but those swabs also picked up DNA that be- longed to other people who had apparently also handled the phone.______________(64),DNA showed up even in swabs that were taken immediately after the phones were scrubbed.That suggests that washing won't removeall traces of evidence from a criminal's device.So cell phones can now be added to the______________(65)of clues that can clinch a crime-scene investigation._________(64)A:GenerallyB:SurprisinglyC:DisappointedlyD:Shortly
To live in the United States today is to gain an appreciation for Dahrendorf′s assertion that social change exists everywhere. Technology, the application of knowledge for practical ends, is a major source of social change. Yet we would do well to remind ourselves that technology is a human creation; it does not exist naturally. A spear or a robot is as much a cultural as a physical object. Until humans use a spear to hunt game or a robot to produce machine parts, neither is much more than a solid mass of matter. For a bird looking for an object on which to rest, a spear or robot serves the purpose equally well. The explosion of the Challenger space shuttle and the Russian nuclear accident at Chernobyl drive home the human quality of technology; they provide cases in which well-planned systems suddenly went haywire and there was no ready hand to set them right. Since technology is a human creation, we are responsible for what is done with it. Pessimists worry that we will use our technology eventually to blow our world and ourselves to pieces. But they have been saying this for decades, and so far we have managed to survive and even flourish. Whether we will continue to do so in the years ahead remains uncertain. Clearly, the impact of technology on our lives deserves a closer examination. Few technological developments have had a greater impact on our lives than the computer revolution. Scientists and engineers have designed specialized machines that can do the tasks that once only people could do. There are those who assert that the switch to an information-based economy is in the same camp as other great historical milestones, particularly the Industrial Revolution. Yet when we ask why the Industrial Revolution was a revolution, we find that it was not the machines. The primary reason why it was revolutionary is that it led to great social change. It gave rise to mass production and, through mass production, to a society in which wealth was not confined to the few. In somewhat similar fashion, computers promise to revolutionize the structure of American life, particularly as they free the human mind and open new possibilities in knowledge and communication. The Industrial Revolution supplemented and replaced the muscles of humans and animals by mechanical methods. The computer extends this development to supplement and replace some aspects of the mind of human beings by electronic methods. And it′s the capacity of the computer for solving problems and making decisions that represents its greatest potential and that poses the greatest difficulties in predicting the impact on society. The author considers the introduction of the computer as a revolution mainly because _____________.A.it gives rise to mass productionB.it can do the tasks that could only be done by people beforeC.it has helped to switch to an information technologyD.it has a great potential impact on society

It was a case of emergency．The four-year-old girl awoke and smelled smoke．She couldn't wake her mother,so she dialed"zero",An operator immediately called the fire department．Help was sent,and a tragedy avoided.Days before this emergency,the mother had taught her child how to telephone for help．Children as young as two and one-half years old can be taught to use the phone in emergency situations．Here are some points.Memorizing certain facts is important．Teach your children their names,and the section of town where you live．Try to keep what they learn within their abilities．Simple information,learned well,is better than difficult information only partly learned.Be sure your children know how to use the telephone．They should be taught to dial"zero"for the operator,at the very least．And they should be taught to dial"911"if it is used in your town.Practice over a period of several days．Over-learning is necessary so the child can act automatically in case of emergency.If you would like a booklet giving instructions on calling for help,write Telephone For Help,Box 99,Bowling Green Station,New York,NY 10004.What is the main idea of the passage?A.Give instructions on calling for help,B.Partly-learned information is uselesC.Teach children how to deal with emergencieD.Keep what children learn within their abilitie
