tryingtosearchandexplorenow.以上三句的時(shí)態(tài)都是正在進(jìn)行時(shí)。PROCESSIt

israiningnow.Iamlisteningtothemusicnow.Wearetryingtosearchandexplorenow.4請(qǐng)根據(jù)謂語(yǔ)動(dòng)詞的公式（謂語(yǔ)動(dòng)詞=助動(dòng)詞+實(shí)意動(dòng)詞）和主謂一致，分析謂語(yǔ)形式中起主要作用的因素是什么？現(xiàn)在分詞beis單數(shù)Idoingam現(xiàn)在進(jìn)行時(shí)謂語(yǔ)形式：is/am/are+doing主語(yǔ)為單數(shù)時(shí)助動(dòng)詞為is,為I時(shí)助動(dòng)詞為am，為復(fù)數(shù)時(shí)助動(dòng)詞為are,

doing不變,因此：謂語(yǔ)動(dòng)詞形式中起主要作用的是助動(dòng)詞be。doing復(fù)數(shù)aredoingPROCESS助動(dòng)詞隨著主語(yǔ)變化而變化。實(shí)意動(dòng)詞不變。請(qǐng)根據(jù)謂語(yǔ)動(dòng)詞公式（謂語(yǔ)動(dòng)詞=助動(dòng)詞+實(shí)意動(dòng)詞），把時(shí)間改為過(guò)去的某一段時(shí)間，并分析謂語(yǔ)形式的影響因素。時(shí)間從現(xiàn)在變成過(guò)去，主語(yǔ)為單數(shù)和I時(shí)助動(dòng)詞為was；主語(yǔ)為復(fù)數(shù)時(shí)助動(dòng)詞為were，因此：時(shí)間改變，謂語(yǔ)動(dòng)詞形式的影響因素還是助動(dòng)詞。Itisrainingnow.Wearetryingtosearchandexplorenow.was單數(shù)Idoingwas過(guò)去進(jìn)行時(shí)謂語(yǔ)形式：was/were+doingdoing復(fù)數(shù)weredoingItwasrainingatthistimeyesterday.Iamlisteningtothemusicnow.Iwaslisteningtothemusicatthistimeyesterday.Weweretryingtosearchandexploreatthistimeyesterday.助動(dòng)詞隨著時(shí)間變化而變化。實(shí)意動(dòng)詞不變。PROCESS思考：過(guò)去進(jìn)行時(shí)謂語(yǔ)動(dòng)詞形式was/were+doing的實(shí)意動(dòng)詞為什么要用現(xiàn)在分詞doing呢？現(xiàn)在進(jìn)行時(shí)和過(guò)去進(jìn)行時(shí)都用doing形式”表示（持續(xù)）進(jìn)行的狀態(tài)或動(dòng)作。Itisrainingnow.Itwasrainingatthistimeyesterday.由現(xiàn)在變過(guò)去，is變成was,但raining不變，都表示雨一直下，是進(jìn)行的狀態(tài)，所以要用現(xiàn)在分詞。PROCESSAnowpastA助動(dòng)詞不管怎么變。實(shí)意動(dòng)詞都用doing表進(jìn)行或持續(xù)。7過(guò)去進(jìn)行時(shí)的謂語(yǔ)形式謂語(yǔ)動(dòng)詞=助動(dòng)詞+實(shí)意動(dòng)詞過(guò)去進(jìn)行式的謂語(yǔ)形式=was/were(過(guò)去)+doing(進(jìn)行中)請(qǐng)用表格歸納過(guò)去進(jìn)行時(shí)的謂語(yǔ)形式。總結(jié)歸納記憶技巧：was/were是過(guò)去，doing是進(jìn)行，過(guò)去進(jìn)行式,was/were加doing。實(shí)際操練根據(jù)圖畫(huà)和所給的提示，用過(guò)去進(jìn)行時(shí)造句。A.WhatwasJayzhoudoingatthistimeyesterday?B.Hewas…atthistimeyesterdayat8a.m.thismorningfrom4to5lastSunday1.IfirstmetLisathreeyearsago.She___ataradioshopatthetime.A.hasworked
