定語從句和同位語從句的區別含義定語從句和同位語從句都是從句，它們在句子中都充當特定的語法角色，但它們的作用和位置略有不同。定語從句：定語從句用來對一個名詞或代詞進行限定或修飾，通常在主句中，與被修飾的名詞或代詞關聯緊密，用來進一步說明或限定其含義。定語從句通常由關系詞（如who,whom,whose,which,that等）引導，并且這個從句可以被省略。例子：Thebookthatisonthetableismine.（在桌子上的那本書是我的。）同位語從句：同位語從句是一種從句，用來對另一個名詞、代詞或名詞性詞組所表達的概念進行解釋、說明或補充。同位語從句與前面的名詞或詞組同位，并且通常用來說明或解釋這個名詞或詞組的含義。同位語從句通常用連接詞（如that,whether,if等）引導。例子：Thefactthatshepassedtheexammadeherparentsproud.（她通過考試這個事實讓她的父母感到驕傲。）在結構上，定語從句和同位語從句的主要區別在于其與名詞或代詞的關系和所起的作用。定語從句用來對名詞進行修飾或限定，而同位語從句則用來對名詞所表示的概念進行解釋或補充。練習:Theidea_______wediscussedlastweekwasquiteinnovative.Thegirl_______wonthefirstprizeismybestfriend.Thefact_______hefailedtheexamsurprisedeveryone.Thebook_______Iborrowedfromthelibraryisquiteinteresting.Thebelief_______youmentionediswidelyheldinmanycultures.Thewoman_______youmetyesterdayismysister.Thecar_______wasparkedoutsidethehousebelongstomyneighbor.Themovie_______wewatchedlastnightwasreallyboring.Thehouse_______isnexttotheparkisforsale.Theman_______iswearingabluejacketismybrother.Thebook_______youremendedisexcellent.Theteacher_______isstandingatthefrontoftheclassroomisMrs.Smith.Theputer_______heboughtlastweekisalreadyoutdated.Thegirl_______wonthesingingpetitionismyfriend.Thehouse_______wevisitedlastweekhasabeautifulgarden.Thedog_______barksloudlybelongstomyneighbor.Themovie_______wewatchedlastnightwasquiteentertaining.Theman_______livesnextdoorisadoctor.Thecar_______wasparkedinfrontofthebuildingwasstolen.Therestaurant_______servesItalianfoodisverypopular.Theproject_______weworkedontogetherwasasuccess.Thepainting_______ishangingonthewallisbyPicasso.Thecat_______issittingonthewindowsillismine.Theuniversity_______sheattendedisknownforitsresearchprograms.Thebike_______heridestoworkneedsrepairs.Thepany_______heworksforisbasedinNewYork.Thesong_______yousangatthepartywasbeautiful.Theteam_______wonthechampionshipcelebratedallnight.Thebuilding_______weliveinisundergoingrenovations.Therestaurant_______weateatlastnighthaddeliciousfood.Theboy_______wonthemathpetitionisveryintelligent.Thecity_______Igrewupinisquitesmall.Thecake_______mymombakedformybirthdaywasdelicious.Theproject_______wehavebeenworkingonformonthsisfinallyfinished.Thewebsite_______youremendedhasusefulinformation.Thedoctor_______examinedmewasverykind.Themovie_______wesawlastweekendwasreallyscary.Thebook_______shelentmeisonthetable.Thepany_______offeredmeajobhasagreatreputation.Thetree_______shadesourbackyardisstartingtoloseitsleaves.Thehope_______thesituationwouldimprovekeptthemgoing.Thediscovery_______theremightbelifeonMarsgeneratedexcitement.Theassumption_______theywereresponsibleforthemessangeredthem.Theissueis_______wecanaffordtobuyanewcar.Weneedtodetermine_______theeventwillbeheldindoorsoroutdoors.Thedebatecenterson_______weshouldinvestinrenewableenergy.Theconcernis_______theeventwillbecanceledduetotheweather.Thebook_______Iborrowedfromthelibraryisonthetable.Thenews_______shepassedtheexambroughtjoytoherfamily.Themovie_______wewatchedlastnightwasreallyinteresting.Thefact_______shewaspromotedsurprisedeveryone.Thecar_______hedrivesisveryold.Thewoman_______wontheawardisafamousactress.Theidea_______hesuggestedwasbrilliant.Thehope_______thesituationwouldimprovekeptthemgoing.Thebelief_______hecouldachievehisgoalsinspiredothers.Thequestion_______weneedtoaddressishowtoreducecosts.I'mnotsure_______wewillbeabletofinishtheprojectontime.Weareconsidering_______totakelegalaction.Thebag_____isonthetableisAmy’s.答案：thatwhothatthatthatwhom/thatthatthatthat/whichwho/thatthat/whichwho/thatthatwho/thatthat/whichthat/whichthat/whichwho/thatthat/whichthat/whichthat/whichthat/whichthat/whichthat/whichthat/whichthat/whichthat/whichthat/whic
