参考答案第一部分（共20小题，每小题1.5分，满分30分）1、D2、D3、D4、D5、B6、D7、D8、C9、B10、B11、C12、B13、A14、B15、C16、B17、A18、B19、D20、B第二部分阅读理解（满分40分）阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。21、1、B2、D3、C22、有驾驶员的飞机，“If…Someofthemfocusonthestateofthepilot.”、“…investigationsoftenfocuson‘humanfactor”☞C选项Pilots’conditionscanbeexcluded.☞关键词planeswithpilots和pilotlessplanes【名师点睛】推理判断题之根据事实细节，推断合理信息。根据事实细节，推断合理信息。推理题要求在理解原文表面文字信息的基础上，作出一定判断和推论，从而得到文章的隐含意义和深层意义。推理题所涉及的内容可能是文中某一句话，也可是某几句话，但做题的指导思想都是以文字信息为依据，既不能做出在原文中找不到文字根据的推理，也不能根据表面文字信息做多步推理。也就是说，要做到判断有据，推论有理，忠实原文。切忌用自己的观点代替作者的本意，切忌片面思考，得出片面结论。1、D推理判断题。第二段提出问题“Wouldthesepeoplefeelanybetterifwecouldgetridofpilotsaltogether?”（如果我们能完全摆脱飞行员的话，这些人会感觉好一点吗？）对于这个问题未给出答案。说明人们对乘坐无人驾驶飞机还有所顾忌。最后一段“Today,itmightbedifficultforpeopletoacceptunmannedplanes…manypeoplearealreadynervousaboutflying,…”(今天，人们可能很难接受无人驾驶飞机，因为当一架飞机停下来时，它会从天上掉下来。当然，许多人已经对飞行感到紧张)。由此可推断出对于此类飞机来说，面临的问题就是要有人乘坐。故选D。2、A推理判断题。第二段“Wouldthesepeoplefeelanybetterifwecouldgetridofpilotsaltogether?”（无人驾驶的飞机感觉好些吗？）及第五段最后“onefundamentalquestionhasn’tbeenansweredyet:Wouldwefeelateaseflyingitwecan’tseetwosmartlydressedpilotsinside,calmlyprovidinguswithweatherupdatesduringastorm?”（一个基本的问题还没有得到回答：我们看不到两个穿着得体的飞行员，在暴风雨期间平静地为我们提供天气的更新，我们是否能轻松地飞行？）第七段“Thereisalsooneworry:theriskoftheunmannedplanegettinghacked”（对黑客的担忧）除从文中可以看到人们对于无人驾驶飞机存在的担忧外，短文末段还总结人们目前还难以接受这种飞机。故选A。23、KathyFletcherandDavidSimpsonhaveasonnamedSanti.Hehasafriendwhosometimesgoestoschoolhungry.SoSantiinviteshimtooccasionallyeatandsleepathishouse.Thatfriendhasafriendandthatfriendhasafriend,andnowwhenyougotodinneratKathyandDavid'shouseonThursdaynighttheremightbe15to20teenagersgatheringaroundthetable,andlatertherewillbegroupsofthemcrashinginthebasementorinthesmallbedroomsupstairs.ThekidswhoshowupatKathyandDavid'shavesufferedthepainsofmodernpoverty:homelessness,hungerandabuse.Andyetbysomemiracle,hostilesoilhasproducedbeautifulflowers.Kidscomefromaroundthecity.Spicychickenandblackriceareserved.Cellphonesarebanned.ThekidswhocallKathyandDavid“Momma”and“Dad”,arepoliteanddothedishes.Birthdaysandgraduationsarecelebrated.Songsareperformed.Ateachmealtheygoaroundthetableandeverybodyhastosaysomethingnobodyelseknowsabouthim.Ateachmealthekidsshowtheirpromisetocareforoneanother.Theadultsinthiscommunitygivethekidsthechancetopresenttheirgifts.“Atmyfirstdinner,EddreadapoemthatIfirstthoughtwasfromLangstonHughes,butitturnedouttobehisown.KesarihasavoicethatsomehowappearsfromNewOrleansjazzinthe1920s.MadelineandThalyaformafriendshipasifitwerethehighestartform,”Georgesaid.“Theygiveusagift—completeintoleranceofsocialdistance.WhenIfirstmetEdd,Iheldoutmyhandtoshakehis.Helookedatitandsaid,‘Wehughere',andwe'vebeenhuggingsince,”Kesarisaid.BillMilliken,aveteranyouthactivi
