超好unit過(guò)去完成時(shí)講解實(shí)用教案

1、“I finished the homework.”“I went out playing with my friends” After I finished the homework, I went out playing with my friends.” Before I went out playing with my friends, I finished the homework.這個(gè)句子是正確的，但有沒(méi)有一種更好的方式來(lái)這個(gè)句子是正確的，但有沒(méi)有一種更好的方式來(lái)連接這兩個(gè)句子，能讓我們更清楚連接這兩個(gè)句子，能讓我們更清楚(qng chu)明明了地表達(dá)出發(fā)生在過(guò)去時(shí)間的先后順序呢？

2、這時(shí)了地表達(dá)出發(fā)生在過(guò)去時(shí)間的先后順序呢？這時(shí)候我們今天的主角過(guò)去完成時(shí)，候我們今天的主角過(guò)去完成時(shí)，had done就要就要閃亮登場(chǎng)了。閃亮登場(chǎng)了。“After I had finished the homework, I went out playing with my friends.” 第1頁(yè)/共25頁(yè)第一頁(yè)，共26頁(yè)。我們先看它的形式：had +過(guò)去分詞，它表示的意義用五個(gè)字就可以概括 。那到底什么叫做“過(guò)去的過(guò)去”，“我寫完了作業(yè)以后出去和朋友玩兒”， “寫完作業(yè)”和“出去玩”這兩個(gè)動(dòng)作都看作是在過(guò)去發(fā)生的，但要注意“寫完作業(yè)”發(fā)生在前，“出去玩”發(fā)生在后，所以比較(bjio)這兩

3、個(gè)同為過(guò)去的動(dòng)作，寫完作業(yè)就是“過(guò)去的過(guò)去”，所以我們要用過(guò)去完成時(shí)，而“出去玩”用過(guò)去時(shí)。After I finished the homework, I went out playing with my friends.” “After I had finished the homework, I went out playing with my friends.” 找不同(b tn)“過(guò)去(guq)的過(guò)去(guq)”第2頁(yè)/共25頁(yè)第二頁(yè)，共26頁(yè)。所以我們說(shuō)使用過(guò)去完成(wn chng)時(shí)有兩個(gè)大前提1兩個(gè)動(dòng)作均發(fā)生在過(guò)去2先發(fā)生的動(dòng)作（過(guò)去的過(guò)去）用過(guò)去完成(wn chng)時(shí)。兩個(gè)
