肥胖現在成了一個社會問題,給人們帶來很多嚴重危害。但人們總是用各種借口來抱怨使自己肥胖的外部因素,而不去下決心解決肥胖問題。1.B2.A詞義推斷題。由第一段最后兩句話“…morepeoplenowdiefrombeingoverweight,orsay,frombeingextremelyfat,thanfrombeingunderweight.It’sthegoodlifethat’smorelikelytokillusthesedays.”可知更多的人死于超重而不是營養(yǎng)不良。這正是今天的好生活殺死了我們。,美文研讀,3.A文章前半部分描述超重的危害,后半部分描述人們明知超重危害尋找各種借口不去減肥。所以文章最好的題目應該是:“行動或借口?!?.(寫段落大意)people’sbeingoverweight,whichbringsaboutharmstotheirhealth.Italsopointsoutthatpeoplealwaystrytofindvariousexcusestocomplainaboutitratherthantakeactiontosolveit,[復記強化]1.Overweight2.willpower3.Blame4.fashion5.Slim6.inviting7.死于8.主要原因9.進展10.減肥,一、句子翻譯1.alarmingincrease,hasagreatimpacton2.quit,whicharouses3.sitaroundfeelingsorry4.There’snodenyingthat,contributeto5.Thegovernmentwillputabanontheuseofthrow-awaychopsticks.,知識運用,6.Wearesupposedtoformthegoodhabitoflivingalow-carbonlife.7.It’sessentialfortheruralleft-behindchildrentoenhancetheirsenseofsafety.8.Onlybyourjointeffortscanwemaintaintheorderofsociety.,二、短文填空①bringsabout②Asaresultof③enjoyingtheconvenience④Ontheotherhand⑤haveabadinfluenceon⑥resultin⑦Inadditionto⑧indanger⑨protectthewildlife,D推理判斷題。在題干中畫出關鍵詞Jennifer和watch,通過尋讀,關鍵詞出現在第一段,通過本段可知,Jennifer在參加在線考試,正在受監(jiān)控器監(jiān)視。但為什么要監(jiān)視她呢?順著往下讀,第二段是描述監(jiān)控器如何監(jiān)視她的一舉一動的,當讀到第三段的首句時,就知道,監(jiān)視她的目的是防止她在考試中作弊;對照各選項,只有選項D正確。,技能導練1,2.A詞義推斷題。這類詞義猜測題信息定位已很清楚,關鍵是理解畫線詞所在的上下文。本句(…thisisthecuttingedge…)中的this指代什么?指代上文的awebcamera,弄清這一點,對照各選項“A.先進技術”“B.磨銳刀具”“C.有效的規(guī)則”“D.分界線”,基本上可以確定答案為A了,因為監(jiān)控器不是“刀具”“規(guī)則”“線”;再根據下句Thetechnologygivestrustto…onlineeducation(這項技術給予學校和在線教育整個體系以信心),可見“Thetechnology”是非常先進的,“Thetechnology”也就是上文提到的用awebcamera防止作弊的技術。此時,完全可以確定選A。,3.B細節(jié)理解題。畫出題干中的關鍵詞valid,通過尋讀,找到本題答案信息在第三段最后一句;這是一個長句,要理解它,首先要分析句子結構,找出主句和從句。show后面的that引導一個賓語從句,主句是以一個“only+狀語”置于句首的倒裝句,強調條件,expertssay是插入語,可以直接忽略,that引導一個賓語從句,即重點理解:Onlywithsolidmeasuresagainstcheating…canuniversityshowthattheirexamsanddiplomasarevalid;然后,理解句意:只有有了打擊作弊的強有力的措施,網絡大學才能表明他們的考試和文憑是有效的。對照各選項,只有B(如果他們能擊敗學術欺騙,網絡大學的考試和文憑才是有效的)與此相符。,4.A細節(jié)理解題。畫出題干中的關鍵詞possiblecheaters,通過尋讀,可將答案信息定位在最后一段第一句:Otherprogramscanproduce…….ones.本句長達34個詞,是個長句。要理解它,首先找到主句和從句,將句子分層理解:(1)Otherprogramscan…by…andcan…by(analyzingwhether)…(2)analyzingwhetherdifficulttestquestionsareansweredatthesamespeedaseasyones;整句意思為“其他程序可以通過設計一系列的問題制作出獨特的考試,通過分析回答難題的速度是否與回答容易題的速度相同,來辨別出學生是否有可能作了弊。”對照各選項,只有A(通過核查答題速度來找到可能作弊的人)正確。,5.C主旨大意題。從題干中的thebesttitle可知,本題屬主旨題,解答這類題的關鍵是找主題句。本文的主題句在第三段第一句(Inthebattleagainstcheating,thisis…onlineeducation),理解主題句,對照各選項,可知C正確。6.somehigh-techmethodstopreventthecheatingintheon-lineeducationbytheexampleofJenifer,[復記強化]1.Equip2.track3.Access4.valid5.Guarantee6.Recognize7.文憑8.身份9.獨特的10.分析,20.hewaswrong,從,連,If21.Itmighthavemadeitalittle…,because,but,it,形容詞,比較級,harder.22.介,for23.and,賓語,what,技能導練2,第一步,跳讀短文,把握大意。rulesandregulationsthatcanhelpustellwhatisrightandmakearightchoice,whichisbeneficialtoourlivinginharmony,butsometimesitisnoteasytotellrightfromwrong,技能導練3,第二步,再次閱讀,選擇答案。1~5ACDAC6~10DADBA11~15DBCBC長難句分析句一:容易,C句二:殘忍,依然,cruel,B,A句三:2,賓,change,different,B,令人困惑的,C.decide,[復記強化]Obey2.choicePredict4.insistGuilty6.starve7.規(guī)章8.可接受的9.故意地10.惡心的,第二步1.新聞2.Japanese,shortenthetimeoftakingabath,energyconsumption,saveenergy,globalwarming3.Japanesegovernmentissuedawhitepaperappealingtothenationtoshortenshowerstosaveenergy.,典型例題,第三步要點(1):議論;一般現在時要點(2):記敘;一般過去時,3.擬好提綱:第一段:Icouldn’tagreemorewiththeJapanesegovernment’saction.第二段:Itremindsmeofmyownexperience…第三段:AsfarasIamconcerned,…,第四步(參考范文)Withthesharpincreaseofhouseholdenergyconsumption,Japanesegovernmentissuedawhitepapercallingonthenationtoshortenshowersandspeedupbathing,withthepurposeofsavingenergyandreducegreenhousegasemissions.Icouldn’tagreemorewiththeJapanesegovernment’saction.Thiscountryisdoingitsbittosaveourearthbyencouragingindividualfromeachfamily.,Itremindsmeofmyownexperienceinsavingenergythissummer.Itwasaveryhotsummer,andtheair-conditionersworkeddayandnight,whichconsumedlotsofenergyandmeanwhileproducedamountsofgases,suchascarbondioxide.Havinglearntthatthetemperatureintheroomwillnotriseimmediatelyafterweturnofftheconditioner,Ipersuadedmyparentstoturnitoff3minutesbeforewewentout.Bydoingsothewholesummerwehappilyfoundthatwesavednearly100yuan.Justimaginehowmuchgreenhousegaswaspreventedfromemittingintotheatmosphere.,AsfarasIamconcerned,itiseasytosaveenergyinourdailylife.Aslongaseveryoneofuscontributesabittotheworld,wecanreducehugeamountofgreenhousegasandhaveacleanerearth.So,whynottakeaction?,ShirleyMichelandmanyotherAmericanretireesdovoluntaryworkaftertheyretiredfromwork,fromwhichtheybenefitalot.Besides,ithelpsthemtospendtheirtimemorehappilyandmeaningfully.Personally,itisagoodideaforretiredpeopletodovolunteerworktospendtheirtimeinameaningfulway,fortheretiredpeoplecanachieveasenseofusefulnesstothesocietybyhelpingtheneedyandmakingcontributionstosociety.,實戰(zhàn)演練,Infact,aretiredpersoncanalsoleadarichandfulllifebydoingmanythings,andmygrandpaisaconvincingexample.Afterretirement,mygrandpaisevenbusierthanbefore.Hetakespartinthelocalassociationofphotographyandoftengoesouttot
