经典word整理文档,仅参考,双击此处可删除页眉页脚。本资料属于网络整理,如有侵权,请联系删除,谢谢!托福口语培训:练习的几个技巧一.关键提升英文表达能力托福口语的前一个评分点是考生作答的语音清楚度和速度节奏.具体来说,包括了考生的发音.语气语调.停顿节奏等.而中国考生往往会陷入两个极端,要么在表达过程中结结巴巴,听上去一点也不流畅,要么像背书一样,机械地死记硬背,刻板生硬.英语是母语的人士是较好的老师,所以大家可以在平时注意听英语广播或者英文电影,多听他们的发音,还要注意看他们的口形.想要提升英语表达能力,必须要通过不断地练习来实现.二.重视语言组织结构能力对于绝大多数中国考生来说,面对考官时〝无话可说〞和〝头脑一片空白〞是常见的场景,考生可以从两方面着手改善:1.独立口语:托福口语中Task12为独立口语,是两道开放性话题,很多考生都会头脑空空,建议大家不要去背那些模板,不但千篇一律,说出的内容也是十分空洞.平时可以多看一些英语名著或杂志,把里面好的素材词句摘抄并背下来,这样考试的时候才会〝有话可说〞.2.综合口语:托福口语中Task3-6是综合口语,要求学生先进行阅读和听力,再根据相关信息作答.大部分考生的作答往往结构混乱,甚至没有围绕主题.针对这个问题,考生可以在平时复述听到的英语,〝影子跟读法〞能有效地解决这个问题.三.语言应用能力提高不易口语评分后面一个点是语言应用能力,其中包含用词用句以及语法准确度.很多考生在口语表达的时候会不自觉的犯一些低级错误,比如单复数.时态语态.人称变化等.这些问题虽然不会影响意思,但是对考官来说听着会很刺耳.大家可以在平时的口语练习中将自己的口语作答用笔写下来,这样可以发现自己的问题并加以改正,还能看是否能用更加简洁明快的句型,从而提高语言运用的多样性.以上就是为大家分享的,大家在托福学习中无论遇到什么问题,都欢迎大家随时与我们互动解决!最后,预祝大家在托福考试中取得好成绩!托福独立+综合口语托福口语TPO43Task1:YourOwnGoal题目:Peoplesetavarietyofgoalsforthemselvesthroughouttheirlives.Describeonegoalyouwouldliketoachieveinthefuture,ande_plainwhythisgoalisimportanttoyou.Includespecificdetailsinyoure_planation.范文:Asaseniorstudentthatalwayssitinfrontofthelaptoporbooks,IthinkIlikeaveryunhealthylifestyle,youknow,kindofsedentarylifestyle.Actually,Idliketomakesomechangestokeepfit.Asaresult,thegoalI’dliketoachieveinthenearfutureistokeepdoingcertaine_ercisesatleastonceaweek.Firstly,Ineedtostartwithsomeeasysports,likejogging.Thesekindsofsportsdontneedmuchspaceandmanyfacilitiestodo,allyouneedisjustapairofsneakers.Then,afterseveralmonthsofregularjogging,Iwillbegintoshowupinthegymtojointheaerobicsclasses.Inthisstage,Iwillneedgreateramountofe_ercisesandmoreprofessionaltraining.Finally,I’dliketobookabadmintoncourtatleasttwiceamonthtoplayingbadmintonwithmyfamilymembers,whichcanstrengththefamilybondsaswell.Itisnoteasytoachievethisgoalformeactually,becauseIhaveheavyworkloadseveryday.ButonceIdecidedtomakeadifference,Iwillsparemytimeforsports.Becauseforme,it’sreallyimportanttoimprovemyhealthcondition.托福口语TPO43Task2:Full-TimeorPart-Time题目:Somestudentsattendcollegefull-time,whileothersattendcollegepart-time.Whichdoyouthinkisbetter?E_plainwhy.范文:Somepeoplemaybelievethattheyonlyattendcollegepart-time,butIdisagree.Idontunderstandhowuniversitystudentscane_pecttolearnanythingiftheydontattendcollegesforfull-time.First,incollegetheygainthebenefitoftheprofessorsknowledgepreferentially.Thebestprofessorsdomorethanjustgooverthematerialinthete_tbooks.Also,attendingcollegesonanysubjectteachesmorethanjustfacts.Itteachesstudentshowtolearn,howtoabsorbinformationandthenapplywhattheyvelearnedtoothersituations.Personale_periencecanhelppeoplelearnaboutthemselvesandtheworldoutsidetheclassroom,butwhenitcomestolearningaboutacademicsubjects,studentsneedtobeincollegebetterforalongertime.Atlast,ifyoujustattendcollegeforpart-time,thenyouwillmissimportanteventsandchancestomakefriends.Itishardtokeepthesamepacewithothers.So,Iwillchoosetoattendcollegeforfull-time.托福口语TPO43Task3(听力+阅读+题目+范文):UniversityMakesChangestoOrientationProgramReadingPart:UniversityMakesChangestoOrientationProgramMadisonUniversityismakingachangetotheorientationprogramforfirst-yearstudents.Inthepast,aspartoforientation,new,incomingstudentscouldgoonatwo-dayhikingandcampingtriptogetherwithotherincomingstudentsontheweekendbeforeclassesbegin.Inordertoencouragemorestudentstotakeadvantageoftheopportunitytogettoknowoneanotherinaninformalsetting,theuniversitywillnowofferachoiceofactivities:studentswillbeabletoeithergohikingorparticipateinorganizedgroupgamesoncampus.Additionally,theseactivitieswilllastonedayonly,nottwo,achangemanystudentshadrequested.听力部分M:Interesting,isntit?Iwishthey.vemadethischangetwoyearsagowhenwegothere.Thisprogramisgonnabemuchmoreattractivethiswaytolotsmorepeople.W:Why?M:Oh,itsaquestionofchoice.See,noteveryonelikesthesamethings.Thewayitusedtobe,iflikeyoudidntlikesleepinginthetent,youjustdidntparticipate,lotsofpeopledidnt.W:Thatstrue.Ididntgoonthecampingtripmyfirstyear,hikingandcampingisntmything.Butyouknow,IdidfeelImissedoutsomething.M:Right.Plus,theotherreasonthisisgoingtoworkyoudonthavetogiveupyourwholeweekendanymore.Thereareotherthingspeopleneedtodotheirfirstfewdays,youknow,likebuytheirbooks,setuptheirrooms,prepareforthefirstdayclasses,thatkindofthing.Thebigtimecommitmentusedtogetintheway.Question:Themane_presseshisopinionaboutthechangedescribedinthearticle.Brieflysummarizethechange.Then,statehisopinionaboutthechangeande_plainthereasonshegivesforholdingthatopinion.托福TPO综合口语43TASK3范文:范文:Theorientationprogramforfirst-yearstudentswillbechangeintoaone-dayonlytriporcampusevent.Andthemanholdsapositiveviewtowardstheannouncement.Thefirstreasonshefeelsthatnoteveryonelikestodothesamethings.Manystudentsjustmissedouttheorientationprogramsincetheydidn’tlikeit.Theorientationprogramshouldbeinvolvedwithmultipleactivities.Second,themanproposesthischangecansavethewholeweekendfortheincomingstudents.Itisbetterforthosewhoneedtoprepareforthefirstfewdays.Therefore,heagreeswiththatopinion.托福口语TPO43Task4(听力+阅读+题目+范文):PopulationChangesReadingPart:PopulationChangesPopulationsofl
