學習目標通過本節課學習，學生能夠：根據例詞，梳理ar、er、ir、or、ur在單詞中的發音規律，能大致感知重讀、弱讀交替形成的語流節奏特點，能夠區分話語中的重讀和弱讀，形成恰當的語流節奏。（學習理解）Unit6RainorShineSectionAPronunciationvowelsconsonantsarerirorurPronunciation“BossyR”是一個英語自然拼讀中的術語，中文意思是“專橫的R”。它用來描述當字母“R”出現在元音字母后面時，會改變前面元音的發音。這種發音規則也被稱為“R控制的元音”（R-controlledvowels）Pronunciationarerirorur/ɑ?//??//??//?://??//??/hardstart________verbperson________firstbird________shorthorse________wordworld________hurtnurse________Pronunciationar/ɑ?/er,ir,or,ur/??/or/?:/arerirorur/ɑ?//??//??//?://??//??/hardstart________verbperson________firstbird________shorthorse________wordworld________hurtnurse________dollar?sharkfarmsummer?actor?Saturday?servetermshirtcirclesportstormworkworseturkeyreturnListenandrepeatarerirorur/ɑ?//??//??//?://??//??/hardstart________verbperson________firstbird________shorthorse________wordworld________hurtnurse________dollar?sharkfarmsummer?actor?Saturday?servetermshirtcirclesportstormworkworseturkeyreturnar,er,or,ur非重讀/?/Listenandrepeatr音節重讀例詞非重讀例詞ar/a:/hard,start/?/dollar,popular/?:/（在w后）war,warmer/??/verb,person/?/summerir/??/first,bird//or/?:/short,horse/?/actor,doctor/??/（在w后）word,worldur/??/hurt,nurse/?/Saturday其他情況當元音字母后面有兩個r字母時，通常被視為元音字母在重讀閉音節中的發音。例如：hurry/?h?ri/中的u發/?/音，carrot/?k?r?t/中的a發/?/音sorry/?s?ri/中的o發/?/音Summaryforsharkbarkcorepartforkartlargebirdcurvemorebornsmartforkdirtyhorsenursefirstnumberservetargetswirlbackyardwormchoreturtlechargeherundermorningsupernorthworldworkcordword漩渦蠕蟲家務活要價（細）繩曲線Practicear/ɑ?/Markstartedalargepartyatthefarmer'smarket.er/??/It'stheperfectdayforher.ir/??/Thegirlgotaskirtforherthirteenthbirthday.or/?:/There'sagorgeousshorthorsesittingontheporch./??/Worldswithinwords,wordswithinworlds.ur/??/Nurse!OnThursdayIhurtmyselfsurfing.農貿市場get的過去式非常漂亮的門廊??Practicethecurvedpaththroughwhichobjectsinspacemovearoundaplanetorstar（天體國繞行星或恒星運行的）軌道Practicethecurvedpaththroughwhichobjectsinspacemovearoundaplanetorstar（天體國繞行星或恒星運行的）軌道thetimeofyearwhencropsarecutandcollectedfromthefields,ortheactivityofcuttingandcollectingthem,orthecropsthatarecutandcollected收獲時節；收割，收獲；收成PracticeJamesandhisfatherwantedtogofishingattheport.Theydrovetothetacklestoretopickupsomeitems.Theyhadtogetsomefishinglineandajarofworms.
