DAviation()is a big polluter.Globally,the industry generates roughly onebillion tonnes of carbon dioxide(CO2)per year-comparable to that produced byJapan,the world's third-largest economy.Although many governments are regulatingemissions from cars and trucks,air transportation is technologically rooted in oldpatterns.Over the next 30 years,the industry's impact on global warming is set toexceed that of its whole history,since the Wright brothers'first flights in theearly 1900s.Cutting the sector's impact on global warming is high on the agenda.There willbe much talk about the need for action.Ministers from 193 nations will try tonegotiate an industry-wide target for cutting emissions,in line with the goals of theParis climate agreement.However,the preparations indicate most of the focus will beon familiar ideas,such as cleaner forms of jet fuel and schemes to offset()carbonemissions.These ideas are also the least destructive to how the industry operatestoday.The aviation industry's response to the climate challenge is a victory of industrialinterests over reality.The reasons are easy to understand.Airlines often operate onsmall profits.Airports struggle to recover the cost of large investments ininfrastructure(基a础设施).And aircraft manufacturers‘bet the company'each timethey design a wholly new plane.Major segments of the aviation industry are led by bigfirms,which are sensitive to risk and cost.They want the least destructivetechnological options.This approach could prove dangerously narrow.Eliminating aviation's impact onglobal warming means reversing the industry.The longer that reality is ignored,theharder it will be to find effective solutions.Emissions from aircraft cannot be reduced simply by using something new tocapture pollution.It might prove impossible to produce clean enough forms of jet fuelat sufficient scale.And addressing the other climate impacts of aircraft beyond CO2,might require overhauling engines,airframes and on-board storage,in an industry thatis extremely attentive to safety,weight and space.All these make profound changeshard to plan and implement.Experimentation is necded.Airlines,fuel providers and aircraft and enginemanufacturers should test a wide range of ideas to learn what might really work.Someof this research is under way,but governments and companies need to push faster andharder.Getting started will also require understanding how uncertainties in climatescience and technology affect cmission control strategies.32.What can we learn about aviation according to Paragraph 1?A.Its influence on global warming is increasing slightly.B.The CO:produced by it equals 1/3 of that made by Japan.C.Cutting emissions from air transportation is effective.D.It is worsening for the slow development of technology.33.What is the common way to reduce aviation's impact on global warming?A.Use more eco-friendly forms of jet fuel.B.Cut down on the operating industry.C.Improve and innovate technology.D.Adopt renewable cnergy resources.萸请试题（一中版）第6页（共0页）
