表 关于同志近三年现实表现材料材料类招标技术评分表图表与交易pdf视力表打印pdf用图表说话 pdf 述与原文有出入。　　2.[B]细节判断题。themostdifficultthin9是Thehardestlesson的同义改写，故可定位到第3段。该段首句指出最困难的事情是“相信自己”，But所在的句子做了更具体的解释即“对自己的一种坚信，我还是我，尽管不是完美的……坚信自己可以找到一个适合自己的位置”，故选B。A太笼统;由第2段可知他的生活并不是孤单的，他还有父母、老师等的支持，故C错误;D文中没有提到。　　3.[C]句意理解题。本题可用排除法。第3段第3句提到，“如果我不坚信自己，我会崩溃，变成一个坐在轮椅里的废人了，在门廊前度此余生”，由此可知C正确。　　4.[D]细节判断题。根据baseball定位到倒数第2段。从该段最后两句可知棒球和那个男人的鼓励给作者以启示和鼓舞.从而发明了一种叫“滚球”的运动，故选D。该段提到作者以为那个男人是在嘲讽他，但后来在他的激励下有所启发，故A错误;B“给作者留下了深刻印象”在文中没有提及;C中的directly错误，男人的话只是给了作者启发。　　5.[B]细节判断题。最后一段第2、3句表明我们要意识到自己的局限性，在开始时尝试那些遥不可及的东西只会徒劳无益，故B正确;由该段第1句和最后一句可知作者为自己不断设立目标并实现了大部分的目标，故A错误：最后一句的anywaybut可知C错误;文中并没有指出他每次尝试一个目标是因为他自己的局限，故D属干随意捏造。　Ihaveknownveryfewwriters,butthoseIhaveknown,andwhomIrespected,confessatoncethattheyhavelittleideawheretheyaregoingwhentheyfirstsetpentopaper.Theyhaveacharacter,perhapstwo;theyareinthatconditionofeagerdiscomfortwhichpassesforinspiration;alladmitradicalchangesofdestinationoncethejoumeyhasbegun;one,tomycertainknowledge,spentninemonthsonanovelaboutKashmir,thenresetthewholethingintheScottishHighlands.Ineverheardofanyonemakinga"skeleton",asweweretaughtatschool.Inthebreakingandremaking,inthetiming,interweaving,beginningafresh,thewritercomestodiscernthingsinhismaterialwhichwerenotconsciouslyinhismindwhenhebegan.　　Thisorganicprocess,oftenleadingtomomentsofextraordinaryself-discovery,isofanindescribablefascination.Ablurredimageappears,headdsabrushstrokeandanother,anditisgone;butsomethingwasthere,andhewillnotresttillhehascapturedit.Sometimesthe’yeastwithinawriteroutlivesabookhehaswritten.Ihaveheardofwriterswhoreadnothingbuttheirownbooks,likeadolescentstheystandbeforethemirror,andstillcannotfathomtheexactoutlineofthevisionbeforethem.Forthesamereason,writerstalkinterminablyabouttheirownbooks,winklingouthiddenmeanings,superimposingnewones,beggingresponsefromthosearoundthem.　　Ofcourseawriterdoingthisismisunderstood:hemightaswelltrytoexplainacrimeoraloveaffair.Heisalso.Incidentally,anunforgivablebore.Thistemptationtocoverthedistancebetweenhimselfandthereader,tostudyhisimageinthesightofthosewhodonotknowhim,canbehisundoing:hehasbeguntowritetoplease.　　AyoungEnglishwritermadethepertinentobservationayearortwobackthatthetalentgoesintothefirstdraft,andtheartintothedraftsthatfollow.Forthisreasonalsothewriter,likeanyotherartist,hasnorestingplace,nocrowdormovementinwhichhemaytakecomfort,nojudgmentfromoutsidewhichcanreplacethejudgmentfromwithin.Awritermakesorderoutoftheanarchyofhisheart;hesubmitshimselftoamoreruthlessdisciplinethananycriticdreamedof,andwhenheflirtswithfame,heistakingtimeofffromlivingwithhimself,fromthesearchforwhathisworldcontainsatitsinmostpoint.　　1.Thewritersthattheauthorisfamiliarwithconfessthattheywould　　A.workouttheendingofanovelinadvance.　　B.followthewritingmethodslearnedatschool.　　C.remodelthemaincharacterinwriting.　　D.makechangestothestoriestheyfirstconstruct.　　2.Accordingtothepassage,theprocessofwriting　　A.dependsonskillfulplanning.　　B.ispredictableandmethodological.　　C.dependsonthewriters'experiences.　　D.isdisorderlyandunsystematic.　　3.Theword"undoing"inthethirdparagraphprobablysuggests　　A.success.　　B.happiness.　　C.failure.　　D.sorrow.　　4.Accordingtothepassage,thewriterhasnorestingplacebecause　　A.heisnotclearaboutwhathewillwriteatthebeginning.　　B.heshouldconstantlyedithisworktomakeitperfect.　　C.hehastofacealotofresponsesgivenbyreaders.　　D.heshouldaddbrushstrokestotheappearingblurredimages.　　5.WhichofthefollowingstatementsaboutwritersisTRUEaccordingtothelastparagraph?　　A.Theyhavelittleideasbeforetheystartwriting.　　B.Theirtalentgoesintoalltheirdrafts.　　C.Itdoesharmtotheirwritingwhentheyflirtwithfame.　　D.Theytrytoincreasecommunicationwithreaders.　　答案解析：　　1.[D]细节判断题。根据familiarwith，confess及各选项内容定位到第1段。第1段指出，这些作家在写作前后，作品的内容往往可能发生极大的变化，其中作者提到，有一位作家就将小说的背景从克什米尔搬到了苏格兰高地。由此可见，D的表述符合文意，为本题答案。文中指出，这些作家动笔之前不会有整篇的构思，也不会按学校所教的那样列出提纲，A、B可排除。文中只说作者开始写作时可能心中已经设定了一两个角色，并没有提到会否重新塑造或改变作品的主要角色，故C应排除。　　2.[D]细节推断题。第1段明确指出，作者熟悉的那些作家在写作过程中没有既定的思路，情节设置也往往根据需要或更深了解素材后才做出相应的变化和调整，这就表明，写作过程有点“混乱”，构思也不很系统化;此外，第2段提到。如果作家脑海中出现了朦胧的形象，他们会在此基础上做任意的改动。由此可见，D正确。根据文中介绍，写作过程并没有完整的构思，也无法预见，只是在写作过程中不断完善，可很快将A、B排除。此外。作家在写作的过程中会更多地了解所搜集的素材，这也与经历无关，故C也排除。　　3.[C]词义推断题。第3段指出作家如果试图拉近自己与读者的距离，企图通过他人的评论了解自己塑造的形象，就相当于为取悦他人而写作。四个选项中，较能概括这种行为性质的是C。此外，undoing有“毁灭”之义，故C为本题答案。　　4.[B]因果关系题。根据题干中的norestingplace定位到第4段。第4段段首提到：作家的才华体现在初稿，而艺术则体现在之后不断修改的稿子中。第2句以Forthisreason(鉴于此)引出作家不能休息的情形。由此可见，第4段首句的内容，即作家需不断创作和修改作品：以实现由才华到艺术的转变是作家无法休息的真正原因。故8为答案，A、C、D不合文意。　　5.[C]细节判断题。末段末旬指出：“当他追逐名利时，他就脱离了自我生活，脱离了对自己内心最深处世界的探索”，故C符合文意，为本题答案。选项A、D均来自文中，但与末段无关，可排除。B与原文表述“作家的才华体现在初稿，而艺术则体现在之后不断修改的稿子中”不符，可排除。　　Foralongtime,researchershavetriedtonaildownjustwhatshapesus--orwhat,atleast,shapesusmost.Andovertheyears,they'vehadalotofexclamationmoments.Firstitwasourparents,particularlyourmothers.Thenitwasourgenes.Nextitwasourpeers,whoshowuplastbutholdgreatsway.Andallthoseideasweregoodones--butonlyasfarastheywent.　　Somewhere,therewasasortoftemperamentaldarkmatterexertinganinvisiblegravitationalpullofitsown.Moreandmore,scientistsareconcludingthatthisunexplainedforceisoursiblings.　　Fromthetimewear

计划 项目进度计划表范例计划下载计划下载计划下载课程教学计划下载 ，故答案为B。　　2.D)这是一道细节题。根据第一段第三句“Thislandisanimportantpartofthehabitatandmigratoryroutesforseveralendangeredspeciesthatfrequentthepark.”(这片土地是非常重要的，因为这里是几种经常光顾此公园的濒危物种的栖息地和迁徙路线。)可知选项D为正确答案。　　3.C)根据第二段可知，公园当局和地方土地所有者密切合作来保护资源，因此他们的关系是"cooperative"(合作性的)。?　　4.A)这是一道推理题。根据第二段第三句和阅读全文，我们很容易就可以得到这样一个信息：为了保护自然资源和濒危物种，公园管理者限制那些会破坏资源的土地开发。因此选项A为正确答案。　　Certainlynocreatureintheseaisodderthanthecommonseacucumber.Alllivingcreature，especiallyhumanbeings，havetheirpeculiarities，buteverythingaboutthelittleseacucumberseemsunusual.Whatelsecanbesaidaboutabizarreanimalthat，amongothereccentricities，eatsmud，feedsalmostcontinuouslydayandnightbutcanlivewithouteatingforlongperiods，andcanbepoisonousbutisconsideredsupremelyediblebygourmets?　　Forsomefiftymillionyears，despiteallitseccentricities，theseacucumberhassubsistedonitsdietofmud.Itisadaptableenoughtoliveattachedtorocksbyitstubefeet，underrocksinshallowwater，oronthesurfaceofmudflats.CommonincoolwateronbothAtlanticandPacificshores，ithastheabilitytosuckupmudorsandanddigestwhatevernutrientsarepresent.　　Seacucumberscomeinavarietyofcolors，rangingfromblacktoreddishbrowntosandcolorandnearlywhite.Oneformevenhasvividpurpletentacles.Usuallythecreaturesarecucumbershaped-hencetheirname-andbecausetheyaretypicallyrockinhabitants，thisshape，combinedwithflexibility，enablesthemtosqueezeintocreviceswheretheyaresafefrompredatorsandoceancurrents.　　Althoughtheyhavevoraciousappetites，eatingdayandnight，seacucumbershavethecapacitytobecomequiescentandliveatalowmetabolicrate-feedingsparinglyornotatallforlongperiods，sothatthemarineorganismsthatprovidetheirfoodhaveachancetomultiply.Ifitwerenotforthisfaculty，theywoulddevourallthefoodavailableinashorttimeandwouldprobablystarvethemselvesoutofexistence.　　Butthemostspectacularthingabouttheseacucumberisthewayitdefendsitself.Itsmajorenemiesarefishandcrabs，whenattacked，itsquirtsallitsinternalorgansintowater.Italsocastsoffattachedstructuressuchastentacles.Theseacucumberwilleviscerateandregenerateitselfifitisattackedoreventouched;itwilldothesameifthesurroundingwatertemperatureistoohighorifthewaterbecomestoopolluted.?　　1.Accordingtothepassage，whyistheshapeofseacucumbersimportant??　　A.Ithelpsthemtodigesttheirfood.?　　B.Ithelpsthemtoprotectthemselvesfromdanger.?　　C.Itmakesiteasierforthemtomovethroughthemud.?　　D.Itmakesthemattractivetofish.?　　2.Thefourthparagraphofthepassageprimarilydiscusses______.?　　A.thereproductionofseacucumbers?　　B.thefoodsourcesofseacucumbers?　　C.theeatinghabitsofseacucumbers?　　D.threatstoseacucumbers'existence?　　3.Whatcanbeinferredaboutthedefencemechanismsoftheseacucumber??　　A.Theyareverysensitivetosurroundingstimuli.?　　B.Theyarealmostuseless.?　　C.Theyrequiregroupcooperation.?　　D.Theyaresimilartothoseofmostseacreatures.?　　4.WhichofthefollowingwouldNOTcauseaseacucumbertoreleaseitsinternalorgansintothewater??　　A.AtouchB.Food?C.UnusuallywarmwaterD.Pollution.　　1.B)通过阅读文章可以排除选项A、C、D，因为文中没有提及，故选项B为正确答案。?　　2.C)此题为段落主旨题。通过阅读第四段可知作者都是讲述海参的进食习惯，故选项C为正确答案。?　　3.A)此题为推论题。根据最后一段可知海参在受到外界刺激时，会做出一定的反应，这也反映出它的防御机制非常敏感，故A为正确答案。?　　4.B)此题为细节题。根据最后一段可知惟有food不会使海参将体内器官吐出来，故其为正确答案。　　GlacierNationalParkinMontanasharesboundarieswithCanada,anAmericanIndianreservation,andanationalforest.AlongtheNorthForko
