in New York City.With help from Tesla,Westinghouse's firm developed a system using alternatingcurrent(交流电)，which soon became the major form of power delivery.To frame his story,Klein creates the character of Ned,a fictional witness to the progress broughtabout by the steam and electric revolutions in America during one man's lifetime.It's a technique thathelps tum a long narrative into an interesting one.24.What is Klein's understanding of the age of electricity?A.It will come to an end sooner or later.B.It began earlier than people thoughtC.It is a little-studied period of historyD.It is closely linked to the steam age25.What can be inferred about Ned?A.He was born in New York CityB.He wrote many interesting stores.C.He lived mainly in the 19th century.D.He created an electricity company26.What is the text?A.A biography.B.A science report.C.A short story.D.A book review.CThe benefits of regular exercise are well documented but there's a new bonus to add to theever-growing list.New research found that middle-aged women who were physically fit could be nearly90 percent less likely to develop dementia (in later life-and if they did,it came on a decadelater than less sporty women.Lead researcher Dr Helena Horder,of the University of Gothenburg in Sweden,said:"Thesefindings are exciting because it's possible that improving people's cardiovascular()fitness inmiddle age could delay or even prevent them from developing dementia."For the studv.191 women with an average age of 50 took a bicycle exercise test until they weretired out to measure their peak cardiovascular capacity.The average peak workload wasmeasured at 103 watts.A total of 40 women met the criteria for a high fitness level with a capacity of 120 watts or higher.while 92 women were in the medium fitness category.A total of 59 were of low fitness level,with apeak workload of 80 watts or less,or having their tests stopped because of health problemsThese women were then tested for dementia six times over the following four decades.During thattime,44 of the women developed dementia.Five percent of the highly fit women developed dementia,compared to 25 percent of the women with medium fitness and 32 percent of the women with lowfitness."However,this study does not show cause and effect between cardiovascular fitness and dementia,it only shows an association,"said Horder."More research is needed to see if improved fitness couldhave a positive effect on the risk of dementia and also to look at when during a lifetime a high fitnesslevel is most important."She also admitted that a relatively small number of women were studied,all ofwhom were from Sweden,so the results might not be applicable to other groups.27.What is on the ever-growing list mentioned in the first paragraph?A.Exercises suitable for the middle-aged.B.Positive effects of doing exercise.C.Expertmental studies on dementia.D.Advantages of sporty women over men.28.Why did the researchers ask the women to do bicycle exercise?A.To assess their cardiovascular capacity.页
