模拟精练巧押题,高频考点,研析透,高频考点研析透,4,考点,1,标题提炼题,记叙文、说明文和议论文三种文体涉及的不同话题的阅读材料都会考查到标题归纳题。设问形式常有：,(1)What is the best title for this passage?,(2)What can be a suitable title for the passage/text?,(3)Which of the following can be the best title for the passage?,(4)The most suitable title of this passage is,“,”,最佳标题应具备以下三大特征：,概括精准而简洁；,针对性强，标题外延与文章内容恰好相符；,醒目，能引发读者阅读欲望,。,考点1标题提炼题记叙文、说明文和议论文三种文体涉及的不同话,1,一般文章的标题可根据主题句来判断，但在某些文章中，如记叙文，没有明确的主题句，需要根据文中的事实细节，查找文章的,“,主线,”,，归纳出文章的主题。,2,所选文章标题须能概括全文的中心内容。标题是文章的点睛之笔，是文章的灵魂和门面。为吸引读者的注意，标题往往比较醒目,。,1一般文章的标题可根据主题句来判断，但在某些文章中，如记叙,一、,(2020,全国卷,D),The connection between people and plants has long been the subject of scientific research.Recent studies have found positive effects.A study conducted in Youngstown,，,Ohio,，,for example,，,discovered that greener areas of the city experienced less crime.In another,，,employees were shown to be 15,%,more productive when their workplaces were decorated with houseplants,.,一、(2020全国卷D),The engineers at the Massachusetts Institute of Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse,，,even unusual functions.These include plants that have sensors printed onto their leaves to show when theyre short of water and a plant that can detect harmful chemicals in groundwater.,“,Were thinking about how we can engineer plants to replace functions of the things that we use every day,，,”,explained Michael Strano,，,a professor of chemical engineering at MIT,.,The engineers at the Massachus,One of his latest projects has been to make plants glow(,发光,)in experiments using some common vegetables.Stranos team found that they could create a faint light for three-and-a-half hours.The light,，,about one-thousandth of the amount needed to read by,，,is just a start.The technology,，,Strano said,，,could one day be used to light the rooms or even to turn tree into self-powered street lamps.,One of his latest projects has,In the future,，,the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plants lifetime.The engineers are also trying to develop an on and off“switch”where the glow would fade when exposed to daylight.,Lighting accounts for about 7%of the total electricity consumed in the US.Since lighting is often far removed from the power source(,电源,)such as the distance from a power plant to street lamps on a remote highwaya lot of energy is lost during transmission(,传输,),In the future，the team hopes t,Glowing plants could reduce this distance and therefore help save energy.,35,Which of the following can be the best title for the text?,A,Can we grow more glowing plants?,B,How do we live with glowing plants?,C,Could glowing plants replace lamps?,D,How are glowing plants made pollution-free?,【答案】,C,Glowing plants could reduce th,【解析】,标题归纳题。根据最后两段可知，由于照明通常远离电源，在传输过程中会损失大量能源。发光的植物可以缩短这段距离，从而帮助节约能源。结合文章主要说明了绿色植物对人们很有好处，因此麻省理工学院的工程师开发了一种发光植物，文章介绍了他们发明这种植物的过程，以及这种植物的一些优势，指出在未来发光植物有可能取代路灯，达到节约能源的作用。由此可知，,C,选项,“,发光的植物能取代路灯吗？,”,最符合文章标题。故选,C,。,【解析】标题归纳题。根据最后两段可知，由于照明通常远离电源,二、,(2019,全国卷,D,篇,),Bacteria are an annoying problem for astronauts.The microorganisms(,微生物,)from our bodies grow uncontrollably on surfaces of the International Space Station,，,so astronauts spend hours cleaning them up each week.How is NASA overcoming this very tiny big problem?Its turning to a bunch of high school kids.But not just any kids.It is depending on NASA HUNCH high school classrooms,，,like the one science teachers Gene Gordon and Donna Himmelberg lead at Fairport High School in Fairport,，,New York,.,二、(2019全国卷D篇),HUNCH is designed to connect high school classrooms with NASA engineers.For the past two years,，,Gordons students have been studying ways to kill bacteria in zero gravity,，,and they think theyre close to a solution(,解决方案,),“,We dont give the students any breaks.They have to do it just like NASA engineers,，,”,says Florence Gold,，,a project manager.,“,There are no tests,，,”,Gordon says.,“,There is no graded homework.There almost are no grades,，,other thanAre you working towards your goal,？,Basically,，,its Ive got to produce this product and then,，,at the end of the year,，,present it to NASA.Engineers come and really do an inperson review,，,and.its not a very nice thing at times.Its a hard business review of your product,.,”,HUNCH is designed to connect h,Gordon says the HUNCH program has an impact(,影响,)on college admissions and practical life skills.“These kids are so absorbed in their studies that I just sit back.I dont teach.”And that annoying bacteria?Gordon says his students are emailing daily with NASA engineers about the problem,，,readying a workable solution to test in space,.,Gordon says the HUNCH program,35,What is the best title for the text?,A,NASA,：,The Home of Astronauts,B,Space,：,The Final Homework Fro
