◇ The Past Continuous
過去進行式
過去進行式是指「過去某個時間點」或是「某段時間內」正在發生或持續的動作、狀態，句構是 was/were ＋ 現在分詞，例如 I was writing on a TV show last year，表示我去年「一直」在為一齣電視節目寫腳本。另一個例子是 I was watching Spongebob Squarepants，雖然句中沒有提及確切的時間，但可理解是「過去的習慣」。
Example：
1. I was riding my bike at nine o'clock last night.
昨晚九點鐘我正在騎自行車。
2. The children were staring at us with huge eyes.
孩子們張大了眼睛盯著我們。
3. What were you doing at nine o'clock last night.
你昨晚九點在做什麼？
