肥胖現(xiàn)在成了一個(gè)社會(huì)問(wèn)題,給人們帶來(lái)很多嚴(yán)重危害。但人們總是用各種借口來(lái)抱怨使自己肥胖的外部因素,而不去下決心解決肥胖問(wèn)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(yíng)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(guò)尋讀,關(guān)鍵詞出現(xiàn)在第一段,通過(guò)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(cè)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(guò)尋讀,找到本題答案信息在第三段最后一句;這是一個(gè)長(zhǎng)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(yǔ)從句,主句是以一個(gè)“only+狀語(yǔ)”置于句首的倒裝句,強(qiáng)調(diào)條件,expertssay是插入語(yǔ),可以直接忽略,that引導(dǎo)一個(gè)賓語(yǔ)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(guò)尋讀,可將答案信息定位在最后一段第一句:Otherprogramscanproduce…….ones.本句長(zhǎng)達(dá)34個(gè)詞,是個(gè)長(zhǎng)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(guò)設(shè)計(jì)一系列的問(wèn)題制作出獨(dú)特的考試,通過(guò)分析回答難題的速度是否與回答容易題的速度相同,來(lái)辨別出學(xué)生是否有可能作了弊?!睂?duì)照各選項(xiàng),只有A(通過(guò)核查答題速度來(lái)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(yǔ),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(zhǎng)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(guò)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,whynott
