thegeneticallyengineeredplantsmayharmtheenvironmentandworriedthattheymaybedangerousforpeopletoeat."可知，一些人则担心转基因植物可能会危害环境，并担心人们食用转基因植物会有危险。所以可以推断出作者认为杂交育种是不准确的，可能会引起一些问题，故选B。作者态度题。文章从正反两方面了转基因工程，转基因有植物高产，抗旱，可以抵抗疾病，适应不同的环境，低脂肪，味道好，新鲜等优点，同时也有其缺点，比如对动物有害，可能会导致一些野生植物疯长，等等。所以说作者对待转基因的态度是客观的，故选C。篇章结构题。第一段Introduction：介绍什么是转基因科学；第二段CentralPoint1：转基因植物的优点；第三段CentralPoint2：转基因植物存在的问题；第四段Sub-Point1：转基因植物的优点1；第五段Sub-Point2：转基因植物的优点2；第六段Sub-Point3：转基因植物的优点3；第七段Sub-2020/3/42019年北京房山区高三一模英语试卷房山一模英语https://aibeikeresource.jiaoyanyun.com/#/print?id=55d36e177ae443ab8fc4cf1c794a90f8&type=analyze14/17Point1：转基因植物的缺点1；第八段Sub-Point2：转基因植物的缺点2；第九-十段Concludion：转基因植物有优点也有缺点，需要更多的研究，故选A。四、七选五（每小题2分，共10分）9.A.MysteryofMosquitoFlightThemosquitoisatroublesomeanddangerousinsect.Theirbitesitchandcancarrydangerousdiseases,likemalaria,Zikavirusandyellowfever.Recently,researchersfromBritainandJapandiscoveredhowmosquitoesfly.1Mosquitowingsaresmallandhaveanuncommonshape.2So,howistheirflightpossible?TheteamofscientistsfromBritainandJapansolvedthemystery.Theyusedhigh-speedcamerasandcomputerimagestounderstandthemechanicsofhowtheinsectmovesitswingstostayintheair.3Theysetupeightsuper-highspeedcamerasthattake10,000imageseachsecond.SimonWalker,aresearcherattheUniversityofOxford,explainsthatnormallyatleasttwocamerasareneededtorecordaninsect,sothey'vegotenoughviewsofaninsect.Withtwocameraviewstheycanthentakeanypointonaninsectandcalculateits3-Dcoordinate（三维坐标）.Mosquitoescanspreaddiseases.Theinsecthastwoantenna,ortall,thinorgansonitsheadthatitusestofeelthings.Butitsantennaandsixlegsmakeitdifficulttotakeclearimagesofthewingmovements.4Theextracameraslettheresearchersseethatthemosquito'swingsmoveeighthundredtimeseachsecond.Thatisfourtimesfasterthanmanyinsectsofasimilarsize.Mosquitoesflybymovingtheirwingsinseveraldifferentdirections.Thethintopedgedoftheirwingsmoveforwardfirstandthentheychangedirectionandmovedown.Themovementlooksasifthewingsaredrawingthenumbereight.5Walkersaysthatexistingunmannedflyingdevice'sdonotworkverywelloutsidebecausewindcanaffecttheirflight."Insects,ontheotherhand,dealreallywellwithevenquitewindyconditions.Sounderstandinghowtheycandothisisgoingtobeadvantageoustous,"Theseresearcherssaythatunderstandinghowmosquitoesflymighthelpfindwaystostopthemfromspreadingdiseases.Becauseofthisitishardtobelievethattheyareabletofly.2020/3/42019年北京房山区高三一模英语试卷房山一模英语https://aibeikeresource.jiaoyanyun.com/#/print?id=55d36e177ae443ab8fc4cf1c794a90f8&type=analyze15/17B.C.D.E.F.G.【答案】1：2：3：4：【解析】Mosquitoesevolvedfromotherinsectsabout226millionyearsago.So,theteamneededtouseeightcamerastoviewthewingsfrommanydirections.ResearchersattheUniversityofOxfordtookimagesofmosquitowingmovements.Manymeasureshavebeentriedformosquitocontrol,forexample.Gettingridofbreedingplaces.Thisknowledge,theysay,helpfindwaystostopmosquitoesfromspreadingdiseasesinthefuture.Theresearchteambelievesthemosquitoes'wingmovementscouldhelpinventorsdesignnewflyingdevices.FADCG根据上文Recently,researchersfromBritainandJapandiscoveredhowmosquitoesfly.最近，英国和日本的研究人员发现了蚊子是如何飞行的。可知接下来的内容应该为研究出来的知识带给了我们什么，F选项Thisknowledge,theysay,helpfindwaystostopmosquitoesfromspreadingdiseasesinthefuture.他们说，这些知识有助于找到未来阻止蚊子传播疾病的方法。更好的承接下文Mosquitowingsaresmallandhaveanuncommonshape.蚊子的翅膀很小，形状不常见，故选F。根据上文Mosquitowingsaresmallandhaveanuncommonshape蚊子的翅膀很小，形状很不寻常。和下文So,howistheirflightpossible?那么，它们怎么可能飞行呢？可知空格处应为蚊子无法飞行，A选项Becauseofthisitishardtobelievethattheyareabletofly.因此很难相信它们会飞，起到了承上启下的作用，故选A。根据下文Theysetupeightsuper-highspeedcamerasthattake10,000imageseachsecond.他们设置了8台超高速照相机，每秒拍摄10000张图像。可知此空应该表达为拍摄了翅膀振动的图片，D选项ResearchersattheUniversityofOxfordtookimagesofmosquitowingmovements.牛津大学的研究人员拍摄了蚊子翅膀运动的图像，放在这里，逻辑通顺。故选D。2020/3/42019年北京房山区高三一模英语试卷房山一模英语https://aibeikeresource.jiaoyanyun.com/#/print?id=55d36e177ae443ab8fc4cf1c794a90f8&type=analyze16/175：根据上文Butitsantennaandsixlegsmakeitdifficulttotakeclearimagesofthewingmovements.但是它的天线和六条腿使得很难清晰地拍摄出翅膀运动的图像。可知后面承接的内容应该为用什么样的方式能够清楚拍摄翅膀，C选项So,theteamneededtouseeightcamerastoviewthewingsfrommanydirections.因此，研究小组需要使用八个摄像头从多个方向观察翅膀。较好的承接了下文的Theextracameraslettheresearchersseethatthemosquito'swingsmoveeighthundredtimeseachsecond.额外的摄像头让研究人员看到蚊子的翅膀每秒移动800次。故选C。根据下文Walkersaysthatexistingunmannedflyingdevice'sdonotworkverywelloutsidebecausewindcanaffecttheirflight.沃克说，现有的无人驾驶飞行设备在室外不能很好地工作，因为风会影响它们的飞行可知，文章由蚊子翅膀过渡到了无人驾驶飞行装备，可知这个空应该为由蚊子翅膀振动的规律找到了建造无人驾驶飞行装置的技术，G选项Theresearchteambelievesthemosquitoes'wingmovementscouldhelpinventorsdesignnewflyingdevices.研究小组相信蚊子的翅膀运动可以帮助发明者设计新的飞行装置。较好对应这个意思，故选G。五、书面表达（15分）10.【答案】【解析】假设你是红星中学高三学生李华，你的英国朋友Peter想了解中国近四十年发生的变化以及人们对中国未来发展的期待。请你给他回邮件，内容包括四十年来人们：1.居住环境的变化；2.出行方式的变化；3.对中国未来发展的期待。注意：1.词数不少于50；2.开头和结尾已给出，不计入总词数。DearPeter,Yours,LiHua略。这是一篇应用文写作。2020/3/42019年北京房山区高三一模英语试卷房山一模英语https://aibeikeresource.jiaoyanyun.com/#/print?id=55d36e177ae443ab8fc4cf1c794a90f8&type=analyze17/17第1步：根据提示可知，本篇为一封邮件。假设你是红星中学高三学生李华，你的英国朋友Peter想了解中国近四十年发生的变化以及人们对中国未来发展的期待。请你给他回邮件，内容包括四十年来人们：1.居住环境的变化；2.出行方式的变化；3.对中国未来发展的期待。时态以现在时态为主。第2步：根据写作要求，确定关键词（组），如：beinterestedin（感兴趣），wit
