那么它就成就了梦想.大学英语演讲稿3MissHouismyuniversityEnglishteacher.HerEnglishnameisJenny.Shelookssoweakthatastrongwindmayblowheraway.Sheisnottootall,about150cm.SheisexperienedofEnglishteaching.Sheteachesmeforthreeyears.Intheotherword,sheistheonlyEnglishteacherduringmyhighschoolstudy.Sheisspecial.ShewillshowanEnglishsongtousbeforeherclass.Afewdayslater,shewillaskustofollowthesingingonthetape.Icanstillremembersomesongsshetaughtus.Itisstrangthatshelookssoweak,butnooneinmyclasswillagainstherword.Ithinkmaybeisbecauseherownpersonality.Everyonerespectsher.Sheisseriousinwork,sothatourwholeclass’sEnglishisgood.Happily,sheisourfriendafterclass.Shealwayspalysbadmintonwithus.Sheisalsoreadytohelpusifwehaveanydifficultiy.Inmymind,agoodteacherismorethanamillionbooks.Andshewillbemymentorforever.Jenny,myteacher,Iloveyou.大学英语演讲稿4Wearegoingtocelebratethe60thanniversaryofourmotheland.BeingastudentinChina,Ifeelveryhappyandproud.Withtheteachers'andparents'help,wemakegreatprogresseveryday.Wearegrowinguptogetherwithourmotherland.Withourknowledgeandability,Iamsurewewilldogreatcontributiontothecountry.Thanktothemotherland,wearegoingtobestrongerandstronger.Thefutureforusmustbebrightandhopeful.Let'stryhardforourselves,andforourmotherlandaswell.Ihopeakid,hopefulleyesjade-greengrass,freeofmindandhappyofheartintheheart,alsofromhadaregrets.Regardlessnatureoftheboongrantstillmankindofcreation,naturegiveweabundantofimaginationandinfinitepureandendlessXiathink,althoughtheybesmallbutsolidifyoneheart,theymutuallyholdtohugtoeachother,underthenourishoftheearth,fullexertivesolidifyonecoagulateofheartdint,alsogivenatureoneWenRun4ofgreenspace.Yearbyyear,thespringreturntotheearthagain,itmaybesaid"theprairiefireburnnottoexert,thespringbreezeblowandliving",grasswithitspecialstubborn,walkthroughthefourseasons.Althoughithavenofloriferousfragrance,takelightniceandsecluded;Althoughitdon'thaveGaoDa4oftree,seemtobesoofinsignificant,itbenotsmallbutshame,itoptimismupward,creatorgreenofvastone,itdon'taccountrepayusefulgreendisplaywholeoftheearth.Thelovelygrass,Iappreciateyou,youaretouseyouofofoffer,useyouoftimechangeoneselfofnewlooks,alsochangepeople'sviewpointtoyou.Althoughsometimesblowtokissinthebisebottom,youwouldbetinilylowtofallahead,howeveryoujusttrembledtofallthedustofbody,facestrongly,theAosignagroundofoutstandingonthemud.Youdon'thavetoomanyDiaodecorationandhavenoclamorofcityandcarbearertoofprosperous,buthavegroundsmiletofaceakidespecially,facewhatyoufaceeachhavelifeofperson,passionlife,lifemediumofpeoplealsolovegrassofsmile,becausehaveyouinthelifeofopen-mindedstateofmindandoptimismofattitude,thereisalsobrightandbeautifulsunlight.Althoughsometimesperhapswouldbecontinuoustorain,broughtthegrassoflightgreenexcessiveofbother,moistwithaccumulatewater,totalhavesunlightofreappear.Thespringbreezedoesn'tsmellsoil,thegrasshadagainthrivingofsourceofvitality,grassatmorningofthemorningLouoncemoreletussucktoabsorbandmakeourmoodsreceivebenefittodulcifywithjoysquick.Thegrassof,loveofoffer,makenothingexcitingoflifebecomeChongYing;Grass,thebig-heartedstateofmindrelax,itdidn'tneedtobecoverup,isacontentedfullyenjoybodyinterest;Grass,becauseoflovebuttheUnitedStates,itbesomeandalittlemorecarelesstolovetotolerate,rational,buttouchedtheperson'sinthemind.Theburstoflightbreezeisblowandthechildren'sjoysvoicejokeawakennedmythoughtsandfeelings.Inawakelyandthedimmoonlight,originallytheperson'slifenotisalsosuchasgrasssimilarinfinitesimal,butituseoriginalofgentleness,affectingcharacteristic,likegaudinessofgrassofflexiblejade-green.Thegrainoflife,givehope,grateful,taste,vitality,althoughsometimesverytired,ownlifeofaureolehappinesstoend.大学英语演讲稿5TodayisMonday;Iwakeupat6o’clockinthemorning.ThenIhavemybreakfastathomeandtakethesubwaytoschool.Iamquiteexcitedaboutthisday,becauseourchemistryteacherwillteachustodoaninterestingexperiment.Thisexperimentisabouthowtocreatesoap.Lastweek,thechemistryteacherpromisedthatwewouldhavesomethingfuninthisweek.Makingourownspecialsoapisthemissioninthisclass.Whentheexperiencebegins,thewholeclassisveryexciting;wemixtheoil,waterandlye.Youneedtobeverycareful,becausethelyeisharmfultotheskin.Thenwewillstirtheoilandlyeforabouttenminutes,thechemistryreactionwillmaketheliquidintosolid.Thenthesoapcomesintobeing.Althoughtheprocessistired,wehavealotoffun.Themostimportantthingiswelearnhowtomakesoap.Thetimepassessoquickly,wefeelverybusybutlearnalotofusefulthings.大学英语演讲稿6changetheworld?changeourselvesgoodevening,honorablejudges,ladiesandgentlemen.it’smygreatpleasuretostandheretopresentmyspeech—changetheworld,changeourselves.it’snoticablethatwesternholidaysarebecomingincreasinglypopulardaybyday,whilechinesetraditionalfestivalsarebeingsomewhatneglected.notlongbeforeabout10doctorsinbeijinguniversityandqinghuaunversityannouncedthatweshouldrejecttheinvasionofwesternholidays,becausetheyregardwesternholidaysasanchallengeagainstourtraditionalfestivalsandculture.franklyspeaking,idon’tquiteagreewiththem.indeed,weshouldneverneglectorevendiscardourtraditonalfestivalsaschinaboastsabrillianthistoryan
