　　本單元語法講解

　　過去進(jìn)行時(Past Progressive Tense)

　　句型 S + was/were +V-ing…

　　例A：She was doing her homework at 8:30 yesterday evening.

　　(昨天傍晚八點半她正在做家庭作業(yè)。)

　　例B：We were having supper at that time.

　　(那個時候我們正在吃晚飯。)

　　解說 如例1所示，在單句中使用過去進(jìn)行時來表達(dá)時必須把該動作正在進(jìn)行中的時間表明清楚，否則就不合邏輯了。例如：I was taking a bath yesterday. (錯)

　　(昨天我正在洗澡——昨天24小時都正在洗澡嗎?)

　　所以本句應(yīng)該如例1來表達(dá)，或者用一般過去時表達(dá)如下：

　　I took a bath yesterday.(昨天我洗了澡。)

　　如果由上下文的文意，或者對談中的話意可以了解“動作正在進(jìn)行中的時間”，單句里就使用過去進(jìn)行時來表達(dá)是很普通的，例如：

　　A：I called you up yesterday evening.

　　B：Did you? At what time?

　　A：At around ten o'clock. (大約在十點鐘。)

　　B：Oh, I was taking a bath then.(哦，當(dāng)時我正在洗澡。)

　　過去進(jìn)行時在表達(dá)上常用的句式是如例2所示和另一個一般過去時的動作相搭配。請觀察下面的圖解說明：

　　過去有二動作A和B(如圖示)，在B動作發(fā)生時稍早發(fā)生的A動作正好在進(jìn)行中，所以這種表達(dá)法通常都是復(fù)句(主句+副詞從句)。例如：

　　When I got up this morning, Mother was preparing breakfast in the kitchen.

　　(今天早上我起床時媽媽正在廚房里準(zhǔn)備早餐。—“Mother…。”是主句，“when…，”是副詞從句。)

　　常用于修飾過去進(jìn)行時的時間副詞：過去的某一定點時刻(at + 過去的時刻)，then (= at that time)(那時，當(dāng)時)，all + 時間，“When…/While…/As…”等副詞從句，etc.
