资源描述
肥胖现在成了一个社会问题,给人们带来很多严重危害。但人们总是用各种借口来抱怨使自己肥胖的外部因素,而不去下决心解决肥胖问题。1.B2.A词义推断题。由第一段最后两句话“morepeoplenowdiefrombeingoverweight,orsay,frombeingextremelyfat,thanfrombeingunderweight.Itsthegoodlifethatsmorelikelytokillusthesedays.”可知更多的人死于超重而不是营养不良。这正是今天的好生活杀死了我们。,美文研读,3.A文章前半部分描述超重的危害,后半部分描述人们明知超重危害寻找各种借口不去减肥。所以文章最好的题目应该是:“行动或借口。”4.(写段落大意)peoplesbeingoverweight,whichbringsaboutharmstotheirhealth.Italsopointsoutthatpeoplealwaystrytofindvariousexcusestocomplainaboutitratherthantakeactiontosolveit,复记强化1.Overweight2.willpower3.Blame4.fashion5.Slim6.inviting7.死于8.主要原因9.进展10.减肥,一、句子翻译1.alarmingincrease,hasagreatimpacton2.quit,whicharouses3.sitaroundfeelingsorry4.Theresnodenyingthat,contributeto5.Thegovernmentwillputabanontheuseofthrow-awaychopsticks.,知识运用,6.Wearesupposedtoformthegoodhabitoflivingalow-carbonlife.7.Itsessentialfortheruralleft-behindchildrentoenhancetheirsenseofsafety.8.Onlybyourjointeffortscanwemaintaintheorderofsociety.,二、短文填空bringsaboutAsaresultofenjoyingtheconvenienceOntheotherhandhaveabadinfluenceonresultinInadditiontoindangerprotectthewildlife,D推理判断题。在题干中画出关键词Jennifer和watch,通过寻读,关键词出现在第一段,通过本段可知,Jennifer在参加在线考试,正在受监控器监视。但为什么要监视她呢?顺着往下读,第二段是描述监控器如何监视她的一举一动的,当读到第三段的首句时,就知道,监视她的目的是防止她在考试中作弊;对照各选项,只有选项D正确。,技能导练1,2.A词义推断题。这类词义猜测题信息定位已很清楚,关键是理解画线词所在的上下文。本句(thisisthecuttingedge)中的this指代什么?指代上文的awebcamera,弄清这一点,对照各选项“A.先进技术”“B.磨锐刀具”“C.有效的规则”“D.分界线”,基本上可以确定答案为A了,因为监控器不是“刀具”“规则”“线”;再根据下句Thetechnologygivestrusttoonlineeducation(这项技术给予学校和在线教育整个体系以信心),可见“Thetechnology”是非常先进的,“Thetechnology”也就是上文提到的用awebcamera防止作弊的技术。此时,完全可以确定选A。,3.B细节理解题。画出题干中的关键词valid,通过寻读,找到本题答案信息在第三段最后一句;这是一个长句,要理解它,首先要分析句子结构,找出主句和从句。show后面的that引导一个宾语从句,主句是以一个“only+状语”置于句首的倒装句,强调条件,expertssay是插入语,可以直接忽略,that引导一个宾语从句,即重点理解:Onlywithsolidmeasuresagainstcheatingcanuniversityshowthattheirexamsanddiplomasarevalid;然后,理解句意:只有有了打击作弊的强有力的措施,网络大学才能表明他们的考试和文凭是有效的。对照各选项,只有B(如果他们能击败学术欺骗,网络大学的考试和文凭才是有效的)与此相符。,4.A细节理解题。画出题干中的关键词possiblecheaters,通过寻读,可将答案信息定位在最后一段第一句:Otherprogramscanproduce.ones.本句长达34个词,是个长句。要理解它,首先找到主句和从句,将句子分层理解:(1)Otherprogramscanbyandcanby(analyzingwhether)(2)analyzingwhetherdifficulttestquestionsareansweredatthesamespeedaseasyones;整句意思为“其他程序可以通过设计一系列的问题制作出独特的考试,通过分析回答难题的速度是否与回答容易题的速度相同,来辨别出学生是否有可能作了弊。”对照各选项,只有A(通过核查答题速度来找到可能作弊的人)正确。,5.C主旨大意题。从题干中的thebesttitle可知,本题属主旨题,解答这类题的关键是找主题句。本文的主题句在第三段第一句(Inthebattleagainstcheating,thisisonlineeducation),理解主题句,对照各选项,可知C正确。6.somehigh-techmethodstopreventthecheatingintheon-lineeducationbytheexampleofJenifer,复记强化1.Equip2.track3.Access4.valid5.Guarantee6.Recognize7.文凭8.身份9.独特的10.分析,20.hewaswrong,从,连,If21.Itmighthavemadeitalittle,because,but,it,形容词,比较级,harder.22.介,for23.and,宾语,what,技能导练2,第一步,跳读短文,把握大意。rulesandregulationsthatcanhelpustellwhatisrightandmakearightchoice,whichisbeneficialtoourlivinginharmony,butsometimesitisnoteasytotellrightfromwrong,技能导练3,第二步,再次阅读,选择答案。15ACDAC610DADBA1115DBCBC长难句分析句一:容易,C句二:残忍,依然,cruel,B,A句三:2,宾,change,different,B,令人困惑的,C.decide,复记强化Obey2.choicePredict4.insistGuilty6.starve7.规章8.可接受的9.故意地10.恶心的,第二步1.新闻2.Japanese,shortenthetimeoftakingabath,energyconsumption,saveenergy,globalwarming3.Japanesegovernmentissuedawhitepaperappealingtothenationtoshortenshowerstosaveenergy.,典型例题,第三步要点(1):议论;一般现在时要点(2):记叙;一般过去时,3.拟好提纲:第一段:IcouldntagreemorewiththeJapanesegovernmentsaction.第二段:Itremindsmeofmyownexperience第三段:AsfarasIamconcerned,第四步(参考范文)Withthesharpincreaseofhouseholdenergyconsumption,Japanesegovernmentissuedawhitepapercallingonthenationtoshortenshowersandspeedupbathing,withthepurposeofsavingenergyandreducegreenhousegasemissions.IcouldntagreemorewiththeJapanesegovernmentsaction.Thiscountryisdoingitsbittosaveourearthbyencouragingindividualfromeachfamily.,Itremindsmeofmyownexperienceinsavingenergythissummer.Itwasaveryhotsummer,andtheair-conditionersworkeddayandnight,whichconsumedlotsofenergyandmeanwhileproducedamountsofgases,suchascarbondioxide.Havinglearntthatthetemperatureintheroomwillnotriseimmediatelyafterweturnofftheconditioner,Ipersuadedmyparentstoturnitoff3minutesbeforewewentout.Bydoingsothewholesummerwehappilyfoundthatwesavednearly100yuan.Justimaginehowmuchgreenhousegaswaspreventedfromemittingintotheatmosphere.,AsfarasIamconcerned,itiseasytosaveenergyinourdailylife.Aslongaseveryoneofuscontributesabittotheworld,wecanreducehugeamountofgreenhousegasandhaveacleanerearth.So,whynottakeaction?,ShirleyMichelandmanyotherAmericanretireesdovoluntaryworkaftertheyretiredfromwork,fromwhichtheybenefitalot.Besides,ithelpsthemtospendtheirtimemorehappilyandmeaningfully.Personally,itisagoodideaforretiredpeopletodovolunteerworktospendtheirtimeinameaningfulway,fortheretiredpeoplecanachieveasenseofusefulnesstothesocietybyhelpingtheneedyandmakingcontributionstosociety.,实战演练,Infact,aretiredpersoncanalsoleadarichandfulllifebydoingmanythings,andmygrandpaisaconvincingexample.Afterretirement,mygrandpaisevenbusierthanbefore.Hetakespartinthelocalassociationofphotographyandoftengoesouttotakephotos.Bycontributingthemtosomemagazines,hehasearnedsomemoney,whichisdonatedtothelocalnursinghousetohelptheneedy.EveryS
