When和While引導的時間狀語從句共同點不同點when都可以引導時間狀語從句，意為“當......的時候”引導時間狀語從句時，既可以表示時間點，也可以表示時間段；從句中的謂語動詞既可以是非延續性動詞，也可以是延續性動詞.（多用于過去時態）while引導時間狀語從句時，從句只表示時間段；從句中的謂語動詞必須用延續性動詞。（多用于進行時態）Presentation

notice.過去進行時1、定義：表示過去_________或_________正在進行的動作。2、結構：___________________某個時刻某段時間be(was/were)+V-ing探究學習過去進行時V-ing變化規律：口訣情況構成規則舉例play-playingwrite-writingrun-runninglie-lying直接加-ing去e加-ing雙寫尾字母加-ingie改為y,加-ing一般不發音e結尾重讀輔元輔結尾ie結尾直去雙改小試牛刀：read-__________help-__________shop-__________take-___________swim-__________clean-__________leave-__________die-____________readinghelpingshoppingtakingswimmingcleaningleavingdying探究學習過去進行時可表示兩個動作同時進行。eg:WhileIwasdoingmyhomework,mymotherwascooking.當我寫作業時，我媽媽在做飯。用法：1.過去進行時常表示過去某一時刻或過去某一階段內正在進行的動作。eg:Iwastalkingwithmymotheratthistimeyesterday.昨天的這個時候我正和我媽媽聊天。Fillintheblankswithwas,were,whenorwhile.4bAt7:00a.m.,Iwokeup.______I______makingmybreakfast,mybrother_______listeningtotheradio._______Iwaseating,theradionewstalkedaboutacaraccidentnearourhome.MybrotherandIwentoutrightawaytohavealook.WhilewaswasWhileWhileJohnwascleaninghisroom,Maryturnedontheradio.JohnwascleaninghisroomwhenMaryturned

eg:Ihateditwhenamanspokewithhismouthfulloffood.我討厭人們說話時口里含著食物。一般過去式和過去進行時的區別過去進行時強調動作在過去某時刻正在進行或持續，而一般過去時表示動作的完成。eg:Hewasdoinghishomeworklastnight.他昨晚在寫作業。(不一定寫完)Hedidhishomeworklastnight.他昨晚寫了他的作業。(已經寫完)4cWhatwereyoudoingatthese
