肥胖現(xiàn)在成了一個(gè)社會(huì)問題，給人們帶來很多嚴(yán)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(yīng)該是：“行動(dòng)或借口?！?.(寫段落大意)people’sbeingoverweight,whichbringsaboutharmstotheirhealth.Italsopointsoutthatpeoplealwaystrytofindvariousexcusestocomplainaboutitratherthantakeactiontosolveit,［復(fù)記強(qiáng)化］1.Overweight2.willpower3.Blame4.fashion5.Slim6.inviting7.死于8.主要原因9.進(jìn)展10.減肥,一、句子翻譯1.alarmingincrease,hasagreatimpacton2.quit,whicharouses3.sitaroundfeelingsorry4.There’snodenyingthat,contributeto5.Thegovernmentwillputabanontheuseofthrow-awaychopsticks.,知識(shí)運(yùn)用,6.Wearesupposedtoformthegoodhabitoflivingalow-carbonlife.7.It’sessentialfortheruralleft-behindchildrentoenhancetheirsenseofsafety.8.Onlybyourjointeffortscanwemaintaintheorderofsociety.,二、短文填空①bringsabout②Asaresultof③enjoyingtheconvenience④Ontheotherhand⑤haveabadinfluenceon⑥r(nóng)esultin⑦Inadditionto⑧indanger⑨protectthewildlife,D推理判斷題。在題干中畫出關(guān)鍵詞Jennifer和watch，通過尋讀，關(guān)鍵詞出現(xiàn)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(dòng)的，當(dāng)讀到第三段的首句時(shí)，就知道，監(jiān)視她的目的是防止她在考試中作弊；對(duì)照各選項(xiàng)，只有選項(xiàng)D正確。,技能導(dǎo)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(guān)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(diǎn)，對(duì)照各選項(xiàng)“A.先進(jìn)技術(shù)”“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?yàn)楸O(jiān)控器不是“刀具”“規(guī)則”“線”；再根據(jù)下句Thetechnologygivestrustto…onlineeducation(這項(xiàng)技術(shù)給予學(xué)校和在線教育整個(gè)體系以信心)，可見“Thetechnology”是非常先進(jìn)的，“Thetechnology”也就是上文提到的用awebcamera防止作弊的技術(shù)。此時(shí)，完全可以確定選A。,3.B細(xì)節(jié)理解題。畫出題干中的關(guān)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(gè)長句，要理解它，首先要分析句子結(jié)構(gòu)，找出主句和從句。show后面的that引導(dǎo)一個(gè)賓語從句，主句是以一個(gè)“only+狀語”置于句首的倒裝句，強(qiáng)調(diào)條件，expertssay是插入語，可以直接忽略，that引導(dǎo)一個(gè)賓語從句，即重點(diǎn)理解：Onlywithsolidmeasuresagainstcheating…canuniversityshowthattheirexamsanddiplomasarevalid；然后，理解句意：只有有了打擊作弊的強(qiáng)有力的措施，網(wǎng)絡(luò)大學(xué)才能表明他們的考試和文憑是有效的。對(duì)照各選項(xiàng)，只有B(如果他們能擊敗學(xué)術(shù)欺騙，網(wǎng)絡(luò)大學(xué)的考試和文憑才是有效的)與此相符。,4.A細(xì)節(jié)理解題。畫出題干中的關(guān)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(dá)34個(gè)詞，是個(gè)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(shè)計(jì)一系列的問題制作出獨(dú)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(xué)生是否有可能作了弊。”對(duì)照各選項(xiàng)，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(guān)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(duì)照各選項(xiàng)，可知C正確。6.somehigh-techmethodstopreventthecheatingintheon-lineeducationbytheexampleofJenifer,［復(fù)記強(qiáng)化］1.Equip2.track3.Access4.valid5.Guarantee6.Recognize7.文憑8.身份9.獨(dú)特的10.分析,20.hewaswrong，從，連，If21.Itmighthavemadeitalittle…,because,but,it,形容詞,比較級(jí),harder.22.介,for23.and,賓語,what,技能導(dǎo)練2,第一步，跳讀短文，把握大意。rulesandregulationsthatcanhelpustellwhatisrightandmakearightchoice,whichisbeneficialtoourlivinginharmony,butsometimesitisnoteasytotellrightfromwrong,技能導(dǎo)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(fù)記強(qiáng)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(diǎn)(1)：議論；一般現(xiàn)在時(shí)要點(diǎn)(2)：記敘；一般過去時(shí),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,ithelpst
