第8讲介词和介词短语一、高考（2013）23.It’smucheasiertomakefriends______youhavesimilarinterests.A.unlessB.whenC.eventhoughD.sothat【】B。本题考查状语从句的。本题可以把四个选项分别放到空处，其中只有选项B能使语意通顺，为正确；其他三个选项的意思分别是“除非”，“即使”，“以便”，都不合乎句意，排除。【句意】当有相似的的时候，交朋友就容易的多。【小窍门】把四个选项分别放到句中去，看能否使句意通顺，也是做题的一个技巧。（2013北京）22.Don’tturnoffthecomputerbeforeclosingallprogramsyoucouldhaveproblems.A.orB.andC.butD.so【】A。本题考查并列句的。前面说的是别关电脑，后面说的是关电脑的后果，很显然，中间的意思是“如果关电脑”，如果用词，那就应该用or或者otherwise，因此锁定。【句意】在关闭所有程序之间不要关电脑，否则可能会出。【小窍门】考查的解题关键是弄清句子之间的逻辑，如转折，让步，因果。（2013湖南）23.Youmustlearntoconsultyourfeelingsandyourreason_____youreachanydecision.A.althoughB.beforeC.becauseD.unless【】.B。考查状语从句的。解题思路：理清逻辑。对比reachanydecision和consultyourfeelingsandyourreason，不难看出，兼顾好情感在前，做任何决定在后。【句意】你要学会在做任何决定之前都必须兼顾好情感。（2013江西）28.Shesaysthatshe’llhavetoclosetheshop_____businessimproves.A.ifB.unlessC.afterD.when【】B.考查词义辨析。A.如果；B.如果不；除非；；C.在……之后；D.当……时候【句意】她说如果生意没有好转的话，她将不得不关掉这个商店。（2013课标II）3.IwasgladtomeetJennyagain,_____Ididn'twanttospendalldaywithher.A.butB.andC.soD.or【】Ａ。本题考查并列句的。解题关键是弄清前后句子之间的逻辑。前面说见面高兴，后面却说不想整天跟她呆在一起，明显是转折，要用but。【句意】我很高兴再次见到，但是，我不想一整天都跟她一起度过。(2013陕西)18.Ihaveheardalotofgoodthingsaboutyou_____Icamebackfromabroad.A.untilB.sinceC.whenD.before【】A。本题考查状语从句的。现在完成时态的其中一个用法是 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 示一个动作“从过去的某个时候发生，一直延续到现在”，从本句中的主句是现在完成时，从句是一般过去时来看，整个句子表达的正是这样的一个动作，故用since；如果用until或者before，则主句表示的动作都是发生在从句之前，都应该用过去完成时，排除B，C；如果用when，则主句应该用一般过去时，排除D。【句意】自从我从国外回来，听说了好多关于你的好事情。（2013）4.Readthisstory,_____youwillrealizethatnoteverythingcanbeboughtwithmoney.A.orB.andC.butD.so【】B。本题考查固定句型。“祈使句，+and/then+从句”是一个固定句式，意思是“做某事，你就会如何”。“祈使句+or+从句”意为“做某事，否则你就会如何”。【句意】看看这个故事，你就会明白不是所有的东西都可以用钱买到的。（2013）7.Heissobusy.Hecannotaffordenoughtimewithhisson_____hewantsto.A.evenifB.asifC.becauseD.before【】A。本题考查状语从句。句子的前他不能腾出时间，后他想，前后之间明显是让步，“即使想，也不能”，故正确是evenif。其他三个选项的意思分别是好像，因为，在……之前，均不合句意，排除。【句意】他很忙，即使他很想也不能腾出时间跟儿子一起。（2013）5._____small,thecompanyhasabout1,000buyersinover30countries.A.AsB.IfC.AlthoughD.Once【】C。本题考查的用法。although做意为“尽管，虽然”，符合前后的让步的逻辑；实际上，本句省略了主语和系动词itis。【句意】尽管这家公司很小，但是它在30多个拥有1000多个客户。（2013新课标I）32.There’snowayofknowingwhyonemanmakesanimportantdiscovery_____anotherman,alsointelligent,fails.A.sinceB:ifC.asD.while【】D。本题考查的用法。四个选项都可以作从属使用，引导状语从句。since引导时间状语从句，意思是“自……以来”；引导状语从句，意思是“既然；因为”。if引导条件状语从句，意思是“如果”。as引导时间、、方式、比较等状语从句，意思是“当……的时候；随着……；因为……；像……；和……”等。while引导时间状语从句，意思是“当……的时候”。此外，while还可作并列，表示转折和对比，意思是“然而”，显然符合句意的是选项D。【句意】没办法知道为什么一个人有发现，而另外一个人虽然也很聪明，却没有（发现）。（2013重庆）23.It'snoteasytochangehabits,______withawarenessandself-control,itispossible.A.forB.orC.butD.so【】C。本题考查并列句的。空处前面说的是不容易，后面说的是可能，显然是转折。【句意】改变习惯不容易，但如果是有意识的并且自控，就可能做到。（2013重庆）25.______wehaveenoughevidence,wecan'twinthecase.A.OnceB.AslongasC.UnlessD.Since【】C。本题考查状语从句的。“我们有足够的证据”和“我们不能赢得这个案子”之间的有可能是两种：（1）让步；（2）前面的意思。四个选项中，没有表让步的although/though，那么就应该是前面的意思，用unless，“如果我们没有……，我们就不能……”；其他三个明显与句意不符，排除。【句意】如果我们没有足够的证据，就不能赢这个案子。【小窍门】做这种题，关键是弄清两句话之间的逻辑，比如是因果还是转折等。（2013上海）36.Icannotheartheprofessorclearlyasthereistoomuchnoise_____Iamsitting.A.beforeB.untilC.unlessD.where【】D。本题四个选项都为常见状语从句引导词，A.before引导时间状语从句，“在……之前”；B.until引导时间状语从句，“直到……为止”；C.unless引导条件状语从句，“除非……，如果不……”；D.where引导地点状语从句，“在……的地方”。【句意】“我不能很清楚地听见教授所讲，因为在我坐的地方，有太多的噪音”。显然这里是指我所坐的地方太吵，导致我听不清。(2013北京)26.IhaveanappointmentDr.Smith,butIneedtochangeit.A.toB.offC.withD.from【】C。本题考查介词。haveanappointmentwithsb是固定短语，意思是“与有”。【句意】我跟医生有个，但我得改了。(2013福建)29.Mrs.Smithfindsithardtoclearupthemess,asherchildrenarealways____whenevershetriesto.A.inthewayB.onwatchC.insightD.ontheline【】A。本题考查介词短语的用法。intheway妨碍、挡道；onwatch值班、监视；insight在即、看得见；ontheline处于中、。通过上下文意思可知是孩子们妨碍斯夫人的工作，所以先A。【句意】夫人发现很难收拾这的局面，因为无论什么时候她试图去做的时候，孩子们总是妨碍她的工作。(2013)22Beforeyoupayavisittoaplaceofinterest,lookinyourlocallibraryabookaboutit.A.onB.atC.forD.to【】C。本题考查介词。介词for经常用来表示目的，为正确；其他几个介词均有此意，排除。【句意】在你参观一个名胜之前，在当地馆里查找一本相关的书。(2013)30.Anartistwhowasrecentlytravelingonaferrytothesouthernislanddiscovered______alonglostantiqueGreekvase.A.atrandomB.bychanceC.inturnD.onoccasion【】B。本题考查短语和句意的理解。atrandom任意地，随便地；bychance偶然地，意外地；无意之中；碰巧；inturn轮流地；相应地；onoccasion有时，间或【句意】一个艺术家最近乘坐渡轮到那个南方岛屿旅游，他无意之中竟然发现失传已久的古希腊花瓶。(2013江苏)26.IamalwaysdelightedwhenIreceiveanfromyou.thepartyonJuly1stIshallbepleasedtoattend.A.OnaccountofB.InresponsetoC.InviewofD.Withregardto【】D。本题考查短语介词辨析。A.Onaccountof因为，由于B.Inresponseto对……做出回应C.Inviewof考虑到，鉴于D.Withregardto关于，至于。根据句意，选择D。【句意】当我收到你的电子邮件时，总是很高兴的。关于7月1日的聚会，我将非常高兴参加。(2013辽宁)25.___________everyonehere,Iwishyouapleasantjourneybacktoyourcountry.A.BymeansofB.OnbehalfofC.InsearchofD.Forfearof【】B。本题考查短语介词辨析。A.bymeansof通过……B.onbehalfof代表C.insearchof寻找D.forfearof为了避免，。根据句意可知，选择B。【句意】代表在场的每一个人，我祝您归国旅途愉快。(2013山东)34.TheSmithsarepraised_______thewaytheybringuptheirchildren.A.fromB.byC.atD.for【】D。本题考查介词的用法。A项from“从，来自于”；B项by“通过，被”；C项at“在”；D项意为“因为，为了”，此处表示，符合句意。【句意】夫妇因为他们教育孩子的而受到了称赞。(2013陕西24.Themanagerwantstoseechangesinthecompany,andIamsurehewill.A.inparticularB.inturnC.inchargeD.intime【】D。本题考查介词短语。四个选项的意思分别是“特别，尤其”，“依次，轮流”，“负责”，“及时；”，根据句意，明显是D。【句意】经理想看到公司的变化，我相信他会看到的。(2013新课标Ⅰ)34.Itwasarealracetimetogettheprojectdone.Luckily,wemadeit.A.overB.byC.forD.against【】D本题考查介词用法。题干中的it显然是形式主语，真正主语是不定式togettheprojectdone。根据句意，可知完成这个项目要争分夺秒，所以某种意义上是在和时间赛跑。araceagainsttime是固定短语，意思是“和时间赛跑”，故最佳是D。【句意】完成项目真正是在和时间赛跑。幸运的是，我们赢了。(2013浙江)14.Itwillbeagreathelpifyougotothestoreandgetwhatweneedfordinner._______,I’llsetthetable.A．AsaresultB.OnthewholeC.InthemeanwhileD.Asamatteroffact【】C。考查介词短语。根据上下文句意之间的逻辑，应该是“与此同时”选C【句意】如果去店里买些我们晚饭需要的东西，这会有很大的帮助，与此同时，我将摆好桌子。（2013上海）25.—I'mlookingforanearbyplaceformyholiday.Anygoodidea?—HowabouttheMoonLake?Itis______easyreachofthecity.A.byB.beyondC.withinD.from【】C。本题四个选项都为常见介词，A.by表“通过；经由；在附近；在……之前”；B.beyond表“超过；在……的那一边”；C.within表“在……之内”；D.from表“来自；从……起”。由题干中的关键信息anearbyplace可知，要推荐离城市不远的地方度假。而短语介词withineasyreachof意思是“在…附近，距离…不远”，所以为正确选项。【句意】“——我在寻找附近的地方度假。有什么好主意吗？——月亮湖怎么样？离城市不远的”。二、模拟题1.Jack,Iadviseyoutoreadthisessay_______thedangerofswill-cookeddirtyoil(地沟油)beforeyougotothatrestaurant.A.inB.overC.ofD.on2._______threestrongRepublicofKoreacompetitors,ZhouYangsingle-handedlytookthe1,500-metershort-trackspeedskatinggoldattheVancouverWinterOlympics.A.AgainstB.WithC.ForD.To3.Theaccidentthathappenedatanoilfield_______thecoastoftheBohaiseainhascausedgreatdamagetotheenvironment.A.awayB.fromC.offD.beyond4.Moreconsumersarewaitingforthefurtherdropofhousingpriceswit
