A.wordsthroughthemoutharethemostcommonwayincommunicationB.bodylanguageisthequickestwaytohelppeopleunderstandeachotherC.expressionsarethemostpowerfultooltojudgewhetheramanisconfidentornotD.youmayknowwhatapersonreallythinkswiththehelpofreadinghisbodylanguage選D。推理判斷題。文章首段介紹語言交流只占所有交流方式的10%或者更少。后文介紹體態(tài)語言的重要性,但沒有說明最主要的交流方式是什么,也沒有說體態(tài)語言是最快捷的交流方式或者最強(qiáng)有力的交流工具,故只有D項(xiàng)的說法合理。6.Whatdoestheunderlinedsentencemeaninthesecondparagraph?A.Wecanexpressourselveswellbybodylanguage.B.Weusewordstopreventothersknowingourtruethoughts.C.Spokenwordscanfullyreflectourtrueself.D.Weusebodylanguagetohelpexpressourselves.選B。句意猜測題。根據(jù)下文Butgesturescannotlie.(但體態(tài)語言卻不會(huì)撒謊)及句中hide的意思,可知此句意為:我們用言語來掩蓋真實(shí)意圖,故選B項(xiàng)。7.Youcanseethroughthefeelingsofotherpeopleby______.

A.listeningcarefullytohimB.askingifhecouldfinishataskC.speakingpolitelytohimD.studyinghisgesturescarefully選D。細(xì)節(jié)理解題。根據(jù)第三段中Sothemostusefulwayistoobservehisbodylanguage.可知D項(xiàng)正確。8.Whichofthefollowingstatementsisrightaccordingtothepassage?A.Youcandecidethehonestyofamanbyhiswords.B.Peoplealwayscommunicatewithothersthroughthemouth.C.Facialexpressionsarenotimportantincommunication.D.Gesturesareimportantinpeople’scommunication.選D。推理判斷題。根據(jù)第一段可知B項(xiàng)錯(cuò)誤;根據(jù)第二段首句可知A項(xiàng)錯(cuò)誤;根據(jù)最后一段可知C項(xiàng)錯(cuò)誤;本文主要介紹體態(tài)語言的重要性,故D項(xiàng)正確。Ⅱ.閱讀填句(廣州模擬)根據(jù)短文內(nèi)容,從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。LearningtounderstandspokenEnglishcanbedifficult.Learnersmustnotonlymasternewsounds,butalsolearnconversationalidioms.That’salottolearn!Buttheymaysoonrealizethereissomethingelsegoingon.1Thesedifferentstylesofspeakingarecalled“registers”.Intheirwork,languageexpertsidentifythreemajorfactorsthataffecttheregisterofspokenEnglish:theplaceoftheconversation,therelationshipofthespeakers,andthepurposeoftheconversation.

【文章大意】積累大量高級的詞匯并不難,文中介紹了積累詞匯的方法,并在對話中自動(dòng)運(yùn)用所積累的詞匯。1.tobuild?？疾榉侵^語動(dòng)詞。It是形式主語,真正的主語是tobuildanadvancedandlargevocabulary。2.which?？疾槎ㄕZ從句關(guān)系詞。通過分析句子結(jié)構(gòu)可知,空白處所填的詞指代逗號前的there’senoughroomforimprovement,which在句中為關(guān)系代詞,引導(dǎo)非限制性定語從句,并在句中作主語。3.months。考查名詞的數(shù)。month為可數(shù)名詞,且由afew可知,month應(yīng)用復(fù)數(shù)形式。4.the?？疾楣潭ǘ陶Z。therest剩余的,therestofone’slife余生。5.effective?？疾樾稳菰~。此處要表達(dá)的是“有效的方法之一”,ways是名詞,需要用形容詞來修飾,因此填effective。6.really?？疾楦痹~。此處應(yīng)用副詞修飾動(dòng)詞read。7.sounds?？疾橹髦^一致。這件事并不像聽起來那么難,描述的是一般事實(shí),而且主語為it,因此用sound的一般現(xiàn)在時(shí)的第三人稱單數(shù)形式。8.them?？疾榇~。另一個(gè)好處是你不知不覺中學(xué)到了新詞并且使用它們,作賓語,應(yīng)當(dāng)用賓格形式。9.meaning。考查非謂語動(dòng)詞。作伴隨狀語,表主動(dòng),mean意味著。10.learned/learnt?？疾榉侵^語動(dòng)詞。你自然會(huì)在對話中使用通過讀書學(xué)到的詞匯。learned/learnt作后置定語修飾words,表示“已學(xué)過的詞”,words與learn是被動(dòng)關(guān)系,因此用過去分詞形式。Ⅰ.閱讀理解(鄭州模擬)Veryfewofusbecomefluentinanotherlanguagebystudyingitinhighschool.Iwenttouniversityandthenmovedacrossthecountry,pursuedademandingcareer,marriedandraisedchildren.ImadeanefforttomaintainthelittlebitofFrenchthatIlearnedinschool,buteventuallyrealizedthatthiswaspointless.Iwaswellawarethatnewlanguagesarebestlearnedwhenyoung,andthatourabilitiesinthatregarddeclinewithage.However,justbeforemy50thbirthday,IsignedupforFrenchclasses.AfterIwastestedtoseewhichgroupIbelongedin,Iwasplacedatalmosttheintroductorylevel.WhenIlookedaroundatmyfirstSaturdaymorningclass,IwasstruckbyhowmanyofthestudentswerelearningFrenchasathird,fourth,orevenfifthlanguage.Contrarytomyassumptionthatlearninganewlanguagewasimpossiblydifficult,therewerepeoplewholearnednewlanguagesasamatterofcourse.Ifoundthatitreallywastruethatcertainlinguistic(語言的)abilitiesfadewithage.WhileI’dalwaysthoughtofmyselfasaquicklearner,thatwasnolongerthecase.Iabsorbednewvocabularyveryslowly.WhatIlearnedoneweekseemedtoslipawayassoonasIlearnedthenextskill.Ilookedupthesamewordsandlanguagestructuresoverandoveragain.Now,acoupleofyearsin,IcanlistentothenewsinFrenchandcatch90percentofitonthefirsttry,readanovelifthelanguageisnottoodifficult,andholdupmyendofaconversationifitdoesn’tgotoofast.WhoknowswhatImightstillaccomplish?I’velearnedsomuchbeyondgrammarandvocabulary.I’vemetpeoplefromaroundtheworldandallwalksoflifewhohavethecouragetomakefoolsofthemselvesinordertolearnsomethingnew.I’vebeentaughtbypatientandinspirationalteachersfrommanycornersoftheworld,includingFrance,EasternEurope,theCaribbeanandAfrica.ListeningtothenewsasitispresentedtothepeopleofFrance,Ihavearenewedunderstandingofhowsomethingcanlookcompletelydifferentfromanotherviewpoint.I’velearnedthatalanguageisnotjustasetofwords,butawayofthinking.Butmostofall,I’velearnedthatitreallyisnevertoolatetolearnsomethingnew.【文章大意】本文講述了作者通過學(xué)習(xí)法語的親身經(jīng)歷感悟到學(xué)習(xí)新技能永遠(yuǎn)都不晚。1.WhentheauthortookherfirstFrenchclass,she______.
