it may be “running out of control”.This idea is dangerous.Science can be a force for evil as well as for good.Its applications can be channeled either way,depending on our decisions.The decisions we make,personally or collectively,will determine the outcomes of science.But here is a real danger.Science is advancing so fast and is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference.And,rather than fighting for the best possible policies,we may step back and do nothing.Some people go even further.They say that despite the moral and legal objections,whatever is scientifically possible will be donesomewhere,sometime.They believe that science will get out of control in the end.This belief is dangerous too,because it fuels a sense of hopelessness and discourages them from making efforts to build a safer world.In our interconnected world,the lack of agreement in and out of the world of science can lead to the failure to control the use of science.Without a common understanding,the challenges of “controlling” science in this century will be really tough.Take human cloning for example.Despite the general agreement among scientists on its possible huge impact(影响) on traditional moral values,some countries still go ahead with the research and development of its related techniques.The outcomes are hard to predict.Therefore,discussions on how science is applied should be extended far beyond scientific societies.Only through the united efforts of people with hope,can we be fully safe against the misuse of science and can science best serve mankind in the future.1.What can we conclude from the recent study?A.People think highly of science.B.People hold mixed opinions about science.C.Science is getting dangerously out of control.D.Science is used for both good and bad purposes.答案:B解析:细节理解题。根据文章第一段第一句可知人们对科学的态度喜忧参半,故答案为B项。2.According to the passage,what will happen if we hold that science is getting beyond control?A.The development of science will hopelessly slow down.B.Businesses will have even greater influence on science.C.The public will lose faith in bringing about a bright future.D.People will work more actively to put science under control.答案:C解析:细节理解题。根据第三段最后一句可知,如果科学失控,公众就会对建设光明的未来失去信心,故答案为C项。3.The discussion should reach beyond scientific societies because .A.scientists have failed to predict the outcomes B.the ties between different areas need strengthening C.united efforts are necessary for the development of science D.people need to work together to prevent the bad use of science 答案:D解析:细节理解题。根据文章最后一段最后一句可知答案为D项。4.What is the main idea of the passage?A.Science and its applications bring us many dangers.B.The development of science mostly lies in peoples attitudes.C.Mankind can largely take control of science with their efforts.D.The future of science will be influenced by the dangerous ideas.答案:B解析:主旨大意题。根据文章第一、二段,尤其是第二段中“Science can be a force for evil as well as for good.Its applications can be channeled either way,depending on our decisions.”可知本文的中心是科学的发展在很大程度上取决于人们的态度,故答案为B项。BThe Netherlands on Monday launched its first-ever “intelligent bicycle”,fitted with a set of electronic devices to help bring down the high accident rate among elderly cyclists in this country.The intelligent bicycle runs on electricity.Its seat shakes when other cyclists approach from behind,while the handlebars do the same when obstacles appear ahead to inform cyclists to pay attention to the danger.It also has a cradle(置物架)in which a computer can be inserted,to wirelessly connect and “talk” to the bicycle through a particular application.The computer also flashes a bright signal if there is an approaching obstacle in the bicycles path,like a tree,or if another cyclist comes up from behind intending to pass.A commercial-available bicycle is expected to be on the market in the next two years and should sell for between 1,700 euros to 3,200 euros per bicycle.It weighs about 55 pounds but researchers are working on making the on-board systems smaller.“Accidents often happen when cyclists look behind them or get a fright when they are passed at high speed,”said Maurice Kwakkernaat,one of the scientists involved in the project,“The on-board system technology has already been at work in the automotive industry.”“More and more elderly people are using a bicycle,not only for short distances,but also for longer distances,”Dutch Environment Minister Melanie Schultz van Haegen said.“This type of bicycle is truly needed in the Netherlands because it will help us bring down the number of elderly people who are injured every year and allow them to continue enjoying cycling,” she said.5.What does the text mainly talk about?A.The newly-invented bicycle can warn of danger.B.The intelligent computer runs on electricity.C.More elderly people enjoy electronic devices.D.The means of transportation in the Netherlands.答案:A解析:主旨大意题。根据第一段内容“The Netherlands on Monday launched.in this country.”可知,荷兰在星期一推出了首辆“智能自行车”,这种自行车配备了一套电子设备,用来帮助降低该国骑自行车的老年人的高事故发生率。故选A项。6.When a car appears ahead,the intelligent bicycle will .A.stop by itselfB.make a noiseC.warn its cyclistD.change its color答案:C解析:细节理解题。根据第二段第二句可知,当前方出现障碍物时,自行车把手会摇晃,提醒骑行者注意危险。故选C项。7.What do you know about the intelligent bicycle?A.It uses gas as the fuel.B.It is widely used now.C.It will be lighter in weight.D.It will be free for everyone.答案:C解析:细节理解题。根据第三段最后一句可知,研究人员正致力于使车载系统变得更小。由此可知,这款自行车以后会更轻。故选C项。8.More and more elderly people in the Netherlands .A.try to invent intelligent bicyclesB.enjoy themselves by cyclingC.drive cars for longer distancesD.devote themselves to computers答案:B解析:细节理解题。根据最后一段中的“More and more elderly.for longer distances”以及“This type of bicycle.allow them to continue enjoying cycling.”可知,越来越多的荷兰老年人享受骑车带来的快乐。故选B项。五、七选五阅读理解Applying for college in the United States from another country can be exciting and
