袁隆平是世界著名的农业专家，他1930年出生于北京。在孩童时代，袁隆平就十分聪明，很好地吸取了老师所授的知识。毕业之后，他致力于农业研究。在他的研究中，他对传统的种植方法产生了怀疑，并下定决心在保持种植面积不变的情况下提高水稻产量。在研究过程中，他失败了许多次，但是他从不放弃。除此之外，他还经常整日经受(expose...to暴露)日晒雨淋。最终，他提出了许多先进的理论，并向世界宣布他已经成功研发出了一种新的品种，此品种水稻相比普通水稻可以提高20%的产量。袁隆平认为只有成功地做成某事，他的人生才有意义。我们由此可以得出结论：袁隆平是一位伟大的农业科学家。由于他对农业的巨大贡献，作为“杂交水稻之父”，他将永远被人们铭记。Putourknowlegeintopractice!YuanLongping，aworld-famousagricultural_______，wasborninBeijingin1930.Whenhewasachild，hewasverycleverand_________alltheknowledgewellthattheteacherstaughthim.Aftergraduation，he_________________agriculturalstudy.Duringhisstudieshebeganto______thetraditionalplantingmethodsandwasdeterminedtoincreasericeharvestwithoutincreasingtheareaoffields.Inhisstudyprocess，hewas_________manytimes，buthenevergaveup.Foryourreference!expertabsorbeddevotedhimselftosuspectdefeated__________this，heoften______________therainandsunlightallday.Atlasthe__________manyadvancedtheoriesandhe________totheworldthathehadsucceededindevelopinganewspeciesthatproduceda20percenthigheryieldsthancommontypesofrice.Hethoughtit__________onlyifhecoulddosomethingsuccessfullyinhislife.Wecan______________thatYuanLongpingisagreatagriculturalscientist.Owingtohisgreat__________toagriculture，hewillalwaysbe__________as“FatherofHybridRice”．ApartfromexposedhimselftoputforwardannouncedmadesenseaconclusiondrawcontributionrememberedJohnSnow－adoctor，____________QueenVictoryasherpersonal____________.Buthewaswillingtohelpordinarypeople____________cholera.Manypeopledied____________therewasan____________.Hewantedtofacethe_________andsolvetheproblem.Twotheoriescaughtherattention.Thefirstsuggestedthatcholeramultipliedintheair.Thesecondsuggestedthatpeople____________thisdiseaseintotheirbodiesandthedisease____________thebody.JohnSnow____________thesecondwasrightbutheattendedphysicianexposedtoeverytimeoutbreakchallengeabsorbedattackedsuspectedneededevidence.WhenanotheroutbreakhitLondonin1854，hewasreadytobeginhis.____________andtriedtogetinformation.Hefoundthatmostofthedeathswerenearawater__________andthespreadofthediseasewas____________water.Withtheevidence，hewasableto___________thatpollutedwatercarriedthevirus.Afterthat，hesuggestedthesourceofallthewatersupplies_____________.Finally“KingCholera”was____________.enquirylinkedtoannouncebeexamineddefeatedpumpCopernicus’RevolutionaryTheoryNicolausCopernicusPolishItalymathematician,astronomerCopernicus’Theory•Thesunisthecentreofthesolarsystem.•Theplanetsgoroundthesun,includingtheearth.•Theearthisspinningasitwentroundthesun.•Themoongoesroundtheearth.Whatinspiredhimtoputforwardthetheory?TheOldTheoryTheproblem________arosemovementsbrightnessCantheoldtheoryexplainthesephenomena?Copernicus'TheoryHow?Collectedobservationsofstars，completeitUsedallhismathematicalknowledge….workonitimproveitItshowedthathewass_____withhimselfinhisresearchandhadastrongd__________.tricteterminationOnlyif_______isthecentreofthesolarsystemcanthemovementsoftheotherplanetsintheskymakes____.thesunenseIfIhaveseenfurther,itisbystandingontheshouldersofgiants.IsaacNewtonCopernicus’theoryisnowthebasisonwhichallourideasoftheuniversearebuilt.SignificantHistheorywastotally________fromtheformertheory.differentRevolutionaryShoweditprivatelytohisfriendsin1514Hewas______anddidn’tpublishituntilhelay_____in1543.dyingcautiousIfhehadsuggestedsuchanideaatthattime,hisideawouldhavebeenr______andhewouldhavebeenp_______anda________bytheChristianChurchwhowouldsayitwasa______God’sidea.ejectedunishedttackedgainstobservant,determined,careful,cautious,perseverant,enthusiasticDiscussion•IfyouwereNicolausCopernicus,wouldyouhavehiddenyourtheoryforsomanyyears?Giveyourreasons.1.Apartfromgoingtothepark,Ilimitmymovementstomyneighborhood.2.Itisdifficulttodrawaconclusionwithoutenoughevidence.3.Thescientificenquirieswillcontributetothesuccessofourproject.4.GustaveEiffelisenthusiasticabouthisplantoconstructtheirontower,whichmadehimworld-famous.5.Healwaysputsforwardunusualplans.Sobecautiousbeforeyoudecidetojoinin.6.Whowasthefirstpersontorejecttheidea/theorythattheearthwasthecenteroftheuniverse?7.Althoughhiswritingdoesnotmakesense,Fredispositivethathiscompositionwillscoreahighmark.1.Shewas_______aboutdoingeverythingforfearofmakingmistakes.2.Sheisvery__________aboutEasternmusic.3.Weshouldtrytoovercomeitwhenanydifficulty_______.4.We_______hisideaforsettingupamusicclub,anddecidedtohaveanartclubinstead.5.Whathesaid__________.6.Mr.He____________usinlearningEnglish.cautiousenthusiasticarisesmadesensebestrictwith,cautious,enthusiastic,makesense,arise,rejectrejectedisstrictwithpleasedboreddisappointedsatisfiedscaredannoyedPastparticiple若是及物动词（vt）则表示被动；动作已经完成（即先于谓语动词）若是不及物动词（vi）则只表示完成。如：abrokenglass=aglasswhichhasbeenbrokenafallenleaf=aleafwhichhasfallen(down)一、过去分词作表语（系动词+过去分词）1、过去分词作表语，相当于一个________，表示主语的_____________，既可表示______，又可表示_______。Everyonepresentisveryinspiredathisspeech．Youseemfrightened.Heremainedpuzzled.Hegotpaidbythehour.他按时计酬。HenrysoonbecameinterestedinEnglish.Hefeltlostatthenews.形容词感受或状态被动完成2、过去分词作表语，构成的系表结构与被动语态的区别：Thisdoorisnowclosed．这扇门现在是关着的。Thisdoorisclose
