0Most people who think about such things agree that replacing fossil fuels withrenewableselectricity is the best way to decarbonise industry,transport and the heating and cooling of buildings.动)唱But there are some areas where this is hard.Cement is one.Aviation (is another,becauseoncebatteries are too heavy and hydrogen is too bulky(体积大的)to do the job easily.espeHydrocarbon aviation fuels are thus likely to be around for a while.But such fuels need not befossil.They might be synthesised (from the CO2 from various industrial processes.And astudy just published in Nature,by Aldo Steinfeld of ETH Zurich,a technological university inSwitzerland,and his colleagues,shows how they might be taken from thin air.The process has three stages.First,CO and water are absorbed from the atmosphere using aso-called direct-air-capture device.There,however,the CO,is reacted with basalt rock to dispose ofit.Dr.Steinfeld's system makes use of it.数The second stage is the clever bit.It employs concentrated sunlight to heat a material calledcerium oxide which,when so heated,reacts with both CO,and water.The reaction with COz createscarbon monoxide.The one with water creates hydrogen.In both cases the by-product is oxygen,which goes into the atmosphere.The mixture of carbon monoxide and hydrogen,called syngas,is选列widely used as a raw material.The third step is to turn the syngas into organic molecules ()For the hydrocarbons thatmor如make up aviation fuels,an industrial chemist would normally turn to what is known as the Fischer-4Tropsch process.For their demonstrator,the team chose another route,which led to methanolawa)rather than hydrocarbons.But the general idea is the same.lemIt is suggested that substituting the world's aviation-fuel market entirely in this way would need45,000 km of land.That sounds a lot,but is equal to only about 0.5%of the Sahara Desert.theDr.Steinfeld's equipment does seem to have demonstrated a credible way to go about making the5wstuff.I螺32.What is the purpose of the study?A.To lighten heavy batteries.oC.To make fuels by synthesizing.B.To reduce hydrogen amount.3D.To produce renewable electricity.What does the underlined word "they"in Paragraph 2 refer to?A.The aviation fuels.数C.The industrial processes.B.The industrial fossils.yea34What can we know about the three-staged process?D.The novel batteries.A.Plenty of water and CO,is needed.B.Cerium oxide helps to produce solo energy.C.The team employ a different idea from normal.D.Reactions between chemicals are made full use of.35.What's the author's attitude towards the new finding?A.Doubtful.B.Cautious.第二节（共5小题；每小题2分，满分10分)C.Optimistic.D.Opposed.选项根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余Dogs have a different way of seeing the world compared to human beings.As a resulof this.they heavily rely on their body language to pass their different messages across to peopl36Believe it or not,there are some that you would have never thought of.When puppies start teething,they start chewing things around.But how is it that it's your adudog that chews around?37because it's nothing bad.It just means that they have not beengetting as much physical actias their bodies need.You can easily help them out in this situatioby taking them out for a nice walk or helping them exercise in some other way.42444567890723956789细38.However,a dog will yawn as a sign that they feel safe and very secure where they are.Yawning ia sign of submission and if they do this countless times it just shows how relaxed they areDogs bark for different reasons.If you notice them barking very often and loudly,just know thatit's probably for an urgent reason.inform you about it.39Maybe they have sensed some danger around and are trying to60however,when the barks are shorter and also softer.高三二模·英语第5页（共8页）先享题
