公众的极大兴趣，原因是有各种关于男孩失踪前后天空中出现奇怪光亮和外星人造访地球的报道。人们最后一次看见高中生贾斯廷·福斯特是在星期五晚上。当晚8点，贾斯廷和两个朋友去打棒球，这两个朋友都说贾斯廷打完球就回家了。目击者也说晚上10点45分他们看到贾斯

廷正朝家走去。贾斯廷的妹妹，9岁的凯莉说大约晚上11点她听到哥哥回到家中。‘Iwasgettingreadyforbed，’Kellysaid.‘Justinwentstraighttohisroom.

ginside。“我正准备上床睡觉，”凯莉说，“贾斯廷径直去他的卧室了。我并没有看到他，但我听到他播放自己最喜爱的CD。我上床睡觉了，大约午夜时分我被窗外的亮光弄醒了。”起初，小姑娘以为是满月的光亮，然而接着她意识到光亮在移

动，而且越来越近。“我拉开窗帘，看到一只巨大的飞船在窗外飞行。飞船四周是蓝色的光，还有很多窗户。里面站着许多白皮肤、眼睛又黑又大的奇怪生物。我害怕极了！”Kellysaidthatthespaceshipthenmovedaroundtothesideofthehouse,towa

工作，当这些事件发生时他并不在家。第二天午饭时贾斯廷仍未露面，福斯特夫人开始担心了，于是让丈夫打电话报警。SomepeopleinDoveralsosaythattheysawaliensthatnight.‘It’shappenedtome！’saidMrsMavisWood.‘Th

惊奇的故事。事实上并没有确凿的证据证明是外星人劫持了他。所以，尽管我们不排除这种想法，但是我们也在调查其他的可能性。在查明到底发生了什么事之前，我们是不会放弃的。”A卷Ⅰ阅读理解AOvertheyears,hundreds,ifnottho

nesfromtheirlife.D解析：推理判断题。根据末段的Accordingtohim,Nokartistsusedthefigurinestodescribetheirridinghorsesordonkeysorusingfarmingtools.可知，诺克人从生活中获得灵感，

制作小雕像。BTheworldofnatureisfullofsecrets.Andtheyaresointerestingthatquitealotofpeoplearebusystudyingthem.Allaroundusareanimalsan

ewind.C．IttakesmoretimetoflyfromNYtoLondonthanfromLondontoNY.D．ThejetstreamalwaysblowsfromtheeastacrosstheAtlantic.A解析：推理判断题。从第一段可知大西洋上空特定的气流状

况是影响飞机速度的重要因素。文中“Thereasonforthedifferenceisanatmosphericphenomenonknownasthejet(喷射)stream.”暗示了这一段的主旨。其余三项论述与文章内容不符。10．Theword“shoot”underl

inedinthe2ndpassageprobablymeans“________”．A．sendforB．movequicklyC．comeoutD．growquicklyB解析：词义猜测题。根据下文内容及科学常识我们知道若没有地球引力，建筑物内的

人将可能快速地飞向某一方向。sendfor派人去请；comeout发芽；出版；growquickly快速成长/生长。A、C、D三项含义不对。11．Itcanbeinferredthatwithoutgravity___

_____．A．buildingsandotherstructureswouldfloatawayB．treesandbuildingswouldnotsoeasilyflyoffC．somethingaroundyourheadwouldnotfloa

tawayD．everythingoutsidebuildingswouldflyoffspaceB解析：推理判断题。由第二段中的“ThingsnotattachedtotheEarthwouldflyoffinastraightline.”

以及后文中的例子可知选B项。文章中说的是不固定在地球上的东西在失去地球引力时会四处乱飞，其余三项中的例子都有所偏颇。12．Wherecanwemostprobablyreadthistext?A．Inaresearchp

aper.B．Inashortstory.C．Inatravelmagazine.D．Inastudent’sbook.D解析：推理判断题。文章论述的是较为浅显的科学问题，所以不可能是出自科学论文或旅游杂志。又因为作者是从科学道理和事实方面进行阐述的，所以不是出自故事类

刊物，只能是选于学生用的教材。Ⅱ七选五Ifyou’veeverhadabadnightofsleep,youknowit’sdifficulttostayawakeinclasswhenyou’retired.Classroomscanbeb

拉松比赛，但这次他的参赛目的不是夺取冠军，而是为一个组织筹备资金。1．WhydidKeflezighirunanotherraceafterhehaddecidedtoretire?A．Toraisemoneyforanorganization.B．Toexpressthankfulnesst

oMartin’sparents.C．Totryrunninginthemostdifficultconditions.D．Toencouragepeopletofacedifficultiesbravely.A解析：细节理解题。由第一段中的“Thou

ion(MRF)．”可知，他再次参加比赛是为一个组织筹集资金。2．HowwasMebKeflezighi’slifelikeasachild?A．Hard.B．Lonely.C．Exciting.D．Peacef

ul.A解析：推理判断题。由第二段中的“Keflezighihashadtodealwithmanydifficultiesfromthetimehewasgrowingup...‘Youhadtogotwo,threemilestogetwoodsothatyoucouldhavefire

tocook.’”可推断，Keflezighi幼年时的生活非常艰苦。3．Whatcanwelearnaboutthe2018BostonMarathon?A．ItwassupportedbyMRF.B．Itwasheldinverybadweather.C．Keflezigh

ibrokehisownrecordatthisrace.D．Keflezighidecidedtorunanotherraceafterthisone.B解析：细节理解题。由倒数第三段中的“heavywindsandcol
