Theywerereadingatthistimeyesterday..2.Shewasrunningfrom9:00to11:00thismorning.過去進行時知識講解at3o’clockyesterdayafternoonatthattime/moment，atthistimeyesterday,thismorning,thewholemorning，allday,allnight,from10:00to12:00yesterdaymorning,inthosedays…過去進行時常用的時間狀語：某一時刻atthattime/moment，

atthistimeyesterday，at3o’clockyesterdayafternoon

thismorning,thewholemorning,from10:00to12:00yesterdaymorning,allday,allnight,inthosedays某一段時間過去進行時常和以下時間狀語連用：肯定句：主語+was/were+V-ing+其他Iwasdoingmyhomeworkatthattime.否定句：主語+was/were+not+V-ing+其他Weweren’tplayinggamesattenyesterdaymorning.II.句式結(jié)構(gòu):疑問句：一般疑問句：Was/Were+主語+V–ing+其他?Wasshecooking?特殊疑問句：特殊疑問詞+was/were+主語+V-ing+其他?WhatweretheydoingwhenShellygotup

thismorning?(1).when后可長亦可短，while后面只可長(一進行一發(fā)生)e.g.:

Whenmymumcamein,Iwasplayingthemobilephone.=Mymumcamein,when/whileIwasplayingthemobilephone.主句過去進行時,從句一般過去時主句一般過去時,從句過去進行時III.When/While引導(dǎo)的時間狀語從句用于過去進行時(2)前后都為長，while來把紐帶當。（兩進行）Whilemymumwastalkingonthephone,Iwasdoingmyhomework.=WhileIwasdoingmyhomework,mymumwastalkingonthephone.如：—YouwereoutwhenIdroppedinatyourhouse．—Oh,Iwasshoppinginthesupermarket.IV.有時由上下文暗示出來V.過去進行時與一般過去時的主要區(qū)別:過去進行時強調(diào)動作在過去“正在進行”；一般過去時則強調(diào)動作“發(fā)生”在過去，或狀態(tài)在過去“存在”。例：1.Tinawasshoppingwithhermomatthattime.

(強調(diào)“正在購物”)2.Tinashoppedwithhermomlastnight.

(強調(diào)發(fā)生了“購物”的動作)3.Tinawastiredlastnight.

(強調(diào)過去的狀態(tài))
