定義：表示過去某個時刻或某一階段正在進行的動作。
構成： was/ were + 動詞-ing構成。
用法：1． 表示過去某個時間正在進行的動作。通常由表示過去某一剎那間的狀語： at this/that time，at nine last night等連用。

②at seven this morning i was listening to the radio.
③the teachers were h**ing a meeting from 9 to 10 this morning.今天上午9點至10點老師們在看會。
2．句中沒有明確的時間狀語，需通過上下文語境可以判斷出是過去某時刻正在進行的動作。
①they all worked hard. everybody knew what he was working for.大家都努力工作。人人都知道為什麼而工作。
② a: i beg your pardon, but i didn』t quite catch what you said.對不起，我沒聽清楚你的話。
b: i was asking what you thought of the film.我剛才是問你對這部電影有什麼看法。

②he was swimming all the morning.
③shirley was writing a book about china last year, but i don』t know whether she has finished it. 雪莉去年在寫一本有關中國的書，但我不知道她現在是否完成。（「去年一段時間內在寫」強調動作在進行的情景）
4．從句動作或狀態與主句動作或狀態在同一時間點發生。主句謂語和從句謂語動作都發生在過去，往往是動作時間長的 ( 延續性動詞 ) 用過去進行時，表達談話背景；動作時間短的 ( 瞬間性動詞 ) 用一般過去時，表達新情況。
①the news reached them while(as, when) they were h**ing supper.訊息是在他們吃飯時收到的。
