B．reasonableC．impossible D．unusual答案：D联系空前的Iwasstillamazedwhenhebefriendedafemalegrouse可知，我吃惊的原因显然是“松鸡跟人接触是很少见的，”故选unusual表示“不同寻常的，罕见的”。37．A.though B．becauseC．unless D．until答案：B空前提到Infact，theyarehardtospot；空后又说theyusuallyflyoffwhentheyhearhumanapproaching。前后显然是因果关系。他们很难发现，是因为他们听见人就飞走了，故用because引导原因状语从句。38．A.spring B．summerC．autumn D．winter答案：A后文第48空前有关键信息Asspringwentandsummercame，因此这只松鸡是在春天步入我们的生活的。38．A.got B．keptC．noticed D．imagined答案：C空前提到汤姆是在地里干活，所以他应该是无意当中注意到这只松鸡在地边上走来走去。notice表示“无意当中注意到”，符合语境。40．A.naturally B．certainlyC．normally D．surprisingly答案：D前文第一段提到theyusuallyflyoffwhentheyhearhumanapproaching，因此此处她不害怕显然是令人意想不到，故surprisingly(令人吃惊地，意想不到地)符合语境。41．A.crazy B．curiousC．concerned D．cautious答案：Bbecrazyabout对……着迷；becuriousabout对……好奇；beconcernedabout担心；becautiousabout对……小心翼翼。空前提到shewassurprisinglyunafraid，所以不可能是小心翼翼；不可能是着迷或者担心，只能是对汤姆正在干的事情好奇，故B项正确。42．A.shy B．awkwardC．friendly D．elegant答案：C前文提到这只松鸡在地边走来走去；不害怕，对汤姆干的事情感到好奇，四个选项当中能形容她的只能是friendly；在后文51空前的friendly也给了很好的提示。43．A.careful B．tiredC．fond D．sick答案：C后半句提到我们叫她Mildred，只有喜欢才能给她起名字，故C项正确。grow/befondof喜爱。44．A.supposed B．realizedC．hoped D．pretended答案：D由后半句keptworkingtoseewhatshewoulddonext可知，汤姆是装作没看见她。pretend假装，符合语境。45．A.ignored B．observedC．amazed D．disturbed答案：A前文提到汤姆假装没看见她；后面又提到她跑过来啄汤姆的手，显然是表示“她不喜欢被忽视，被冷落”，故ignore(忽视，忽略)符合语境。46．A.put B．backC．set D．take答案：B由语境可知，这只不喜欢被忽视的松鸡跑过来啄了汤姆的手之后，又后退一下看看汤姆会怎么做。backoff后退，符合语境。47．A.game B．workC．place D．man答案：A由语境可知，Mildred跑过来啄汤姆的手，然后退后看汤姆怎么办；这样的事情持续了20分钟，直到Mildred对此感到厌烦，离开。Mildred厌倦的是重复的这20分钟干的同样的事情；不是工作，地方和人，只能是玩的游戏，故A项符合语境。48．A.giveup B．comeoutC．turnover D．flyby答案：B由语境可知，春天过去了，夏天到了，Mildred跟大家越来越熟悉了，肯定是越来越经常的出来，故comeout出来，符合语境。giveup放弃；turnover翻转；flyby飞过，均不合语境。49．A.Eventually B．SuddenlyC．Constantly D．Presently答案：A由语境可知，Mildred先是在地边上走来走去，然后对我们不害怕，慢慢接近，到最后跟我们待在一起很舒服，这是时间上的顺承关系，故此处填eventually(最后，终于)。50．A.chance B．dreamC．picture D．sense答案：C由语境可知，她呆在汤姆的腿上的时间长到我能跟他们拍照。不可能是机会(chance)，梦想(dream)和sense(感觉)。51．A.comfortable B．guiltyC．anxious D．familiar答案：A前文提到Mildred跟我们呆在一起很舒服，随着时间的推移，她不光跟我们待在一起舒服，跟任何走过的或者是开车经过的人都这样。52．A.lantern B．signC．gunD．loudspeaker答案：B由语境可知，此处表示打猎的季节来临，我们能在马路边挂起的只能是个sign(标牌)，请人们别猎杀我们的松鸡。53．A.drivers B．farmersC．hunters D．tourists答案：C前文提到huntingseason，后文提到hunters，显然我们挂牌子是请猎人别猎杀我们的松鸡。54．A.just B．yetC．thus D．also答案：D由语境可知，我们做出了努力，住在路边的父亲也做出了努力，提醒人们别猎杀她。因此also也，符合语境。55．A.Infact B．ForlongC．Onthecontrary D．Bytheway答案：A后文说，猎人们停下来拍照，因为他们从未见过像Mildred那样的东西。infact事实上；forlong长久；onthecontrary正相反；bytheway顺便说。由语境可知，infact正确。第三部分：阅读理解(共20小题；每小题2分，满分40分)阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。A(·吉林省实验中学高一模块检测)Mostanimalshavelittleconnectionwithanimalsofadifferentkind,unlesstheyhuntthemforfood.Sometimes,however,twokindsofanimalscometogetherinapartnership(伙伴关系)whichisgoodforbothofthem.Youmayhavenoticedsomebirdssittingonthebacksofsheep.Thisisnotbecausetheywantaride,butbecausetheyfindeasyfoodintheparasites(寄生虫)onsheep.Thesheepallowthebirdstodosobecausetheyremovethecauseofdiscomfort.Soalthoughtheycanmanagewithouteachother,theydobettertogether.Sometimesananimalhasaplantpartner.Therelationshipdevelopsuntilthetwopartnerscannotmanagewithouteachother.Thisissointhecorals(珊瑚)ofthesea.Intheirskinstheyhavetinyplantswhichactas“dustmen”，takingsomeofthewasteproductsfromthecoralandgivinginreturnoxygenwhichtheanimalneedstobreathe.Iftheplantsarekilled,orareevenpreventedfromreceivinglightsothattheycannotlivenormally,thecoralswilldie.文章大意：文章介绍自然界中有的动物和动物之间相处的很好，还有的植物和动物是互相依存的关系。56．Somebirdsliketositonasheepbecause________.A．theyenjoytravellingwiththesheepB．theycaneatitsparasitesC．theydependonthesheepforexistenceD．theyfindthepositionmostcomfortable答案：B细节理解题。答案即在“Thisisnotbecausetheywantaride,butbecausetheyfindeasyfoodintheparasites(寄生虫)onsheep.”一句之中。可知鸟喜欢坐在羊的身上，是想吃羊身上的寄生虫，选B。57．Theunderlinedword“they”inthelastsentenceofthefirstparagraphrefersto________.A．birdsandparasitesB.parasitesandsheepC．birdsandsheepD．sheep,birdsandparasites答案：C猜测词义题。前文中的“Thesheepallowthebirdstodosobecausetheyremovethecauseofdiscomfort.”的意思是说：绵羊让鸟儿落在自己身上，因为鸟儿可以将它们身上的寄生虫吃掉。”；另一句“Soalthoughtheycanmanagewithouteachother”的意思是说：尽管它们自己也能对付寄生虫……”。综合上面两句话的意思，再结合“...theydobettertogether”这一句话，可知they指的是鸟和羊，即得答案为C。58．Welearnfromthetextthatcoralsdependonplantsfor________.A．comfort

B．ruinC．liberation D．evolution答案：B由该词后面的句子Wherethebirdsweremostabundant，peoplebelievetherewasanever­lastingsupplyandkilledthembythethousands...，由此可知，旅鸽的丰富性可能会被毁掉，故undoing意为“毁灭”，B项正确。62．Whatwasthemainreasonforpeopletokillpassengerpigeons?A．Toseekpleasure. B．Tosaveotherbirds.C．Tomakemoney. D．Toprotectcrops.答案：C推理判断题。由文章第三段的信息commercialhunters最后一句话Thebirdswereshippedtobigcitiesandsoldinrestaurants可知，人们把旅鸽杀掉主要是为了卖钱，故C项正确。63．WhatcanweinferaboutthelawpassedinMichigan?A．Itwasignoredbythepublic.B．Itwasdeclaredtoolate.C．Itwasunfair.D．Itwasstrict.答案：B推理判断题。由文章最后一段信息butbythen，noseizableflockshadseeninthestatesfor10years可知，在这部法律颁布之前10年，旅鸽就消失了，由此可知，这部法律颁布的太晚了，故B项正确。CMillionsofyearsagothereweremanytypesofdinosaursontheearth.Mostdinosaurswereplanteaters.TheApatosaurus,forexample,hadalongthinnecksothatitcouldeatleavesfromtrees.Otherdinosaursweremeateaters.TheTyrannosaurusRex(霸王龙)killedsmallerdinosaursforfood.Dinosaurswererealanimalsthatoncelivedontheearth，buttheydiedoutabout65millionyearsago.Thedisappearanceofthedinosaursisinsomewayagreatmystery(谜).Somescientiststhinkthattheclimatechangedsuddenly.Fossils(化石)oftreestellusthetemperaturedroppedalotandthatitgotsuddenlymuchcolder.Perhapsthedinosaursweretooslowtochangewiththeclimate.Anewideaisthatameteor(流星)crashedintotheearth.ScientistsdiscoveredaplaceinMexicowheretheythinkthemeteorcrashed.Theythinkthattherewasalotofdustfromthemeteor.Thedustlandedontheplants.Alsothedustblockedthesun'slightforaslongasfiveyears.Manyanimals,includingdinosaurs,wereplanteaters,andperhapsthedustkilledthem.Thismeanstherewasnothingleftformeateatingdinosaurstoeat,andtheydiedout.But,asmanyanimalsfromthattimedidn'tdie，wearenot100%surewhatreallyhappened.文章大意：陆地上的恐龙到底是怎样消失的？原因又是什么？本文对此作了分析：当时陆地上的气候变化和流星撞击地球或许是两个重要的原因。64．Whatarethetwopossibleexplanationstothedinosaurs'disappearance?A．Temperaturedroppingandsealeveldropping.B．Climatechangingandmeteor'scrashing.C．Thedroppingoftemperatureandsealevel.D．Climatechangingandthedustblockingthesun.答案：B细节理解题。从文章第二段可知气候的变化可能是恐龙灭绝的一个原因；从第三段可知流星撞击地球可能是另一个原因；至于海平面的高度文章未提及，故选B。65．Whatdoestheunderlinedword“blocked”inthethirdparagraphmeaninChinese?A．照耀
