    31,In which section of a newspaper may this text appear?A.Business.CSoeial life.B.Entertainment.D.Public health.DScientists have found that floating solar panels called "floatovoltaics"could provide a hugeamount of electricity if they are placed on lakes and reservoir()around the world.Most solar panels are placed on land called solar farms.Any solar panel has to be waterproof sinceit will be out in the rain.Now,a handful of countries are using them,including Brazil,China,India,Indonesia,Singapore,South Korea,Thailand and Vietnam.If local floatovoltaics are adopted further,6,256 cities across 124 countries could fully satisfy their electricity needs,the researchers found.Thiscould largely benefit smaller towns.A little over 70 percent of these cities have a population under50,000,while more populous cities might not have as much space on reservoirs to alone support theirlarge populations.The researchers behind the new study looked at 114,555 reservoirs worldwide.They usedcomputer programs to figure out how much electricity could be produced yearly by covering 30%ofthese reservoirs with floating solar panels.The answer was surprisingly large-more than twice theamount of energy the United States produces in a year.Solar panels work better when they're not extremely hot.The water can cool the solar panels,making floatovoltaics as much as 15 percent more efficient than solar panels on land,which produceless power and need more maintenance()when they overheat.Floatovoltaics can also help savewater by limiting evaporation()from reservoirs.The scientists say that solar panels covering just30%of the reservoirs'surfaces could save as much water as 300,000 people would use in a year.Still,they cost 25 percent more to build than systems on land.They might also reduce oxygenlevels in water,which could hurt fish,and the panels may negatively impact water quality.Thescientists say it will be important to study how floating panels will affect water in each reservoir.Focusing first on man-made reservoirs and canals will avoid some of those problems.32.What can be learnt about floatovoltaics?A.They have not been used worldwide.C.They're only suitable for smaller towns.B.They are used by 70%of all the cities.33.Which is floatovoltaics'advantage,compared with solar farms?D.They can replace solar panels on land.A.They are easier to build.C.They can produce more.B.They cost much less.34.What is the author's attitude to floatovoltaics?D.They are more waterproof.Favorable.B.Doubtful.CObjective.D.Disapproving.a'nugel35.What is the suitable title for the text?yonom leol gaol aoAFloatovoltaics:Speeding Reservoir ConstructionB.Floatovoltaics:Fighting against Climate ChangeC.Floatovoltaics:Making Full Use of Water on EarthD.Floatovoltaics:Making Energy and Saving Watermod no e1-(102 0国考1号19·英语第5页(共8页)
