用法1：用來描述一個過去特定的時(shí)刻正在發(fā)生的事情。

用法2：過去進(jìn)行時(shí)態(tài)還常常和一般過去時(shí)配合使用。此時(shí)，過去進(jìn)行時(shí)態(tài)通常表示一個歷時(shí)較長的體現(xiàn)“背景”的動作或狀態(tài)；而一般過去時(shí)態(tài)則表示此“背景”下發(fā)生的、短暫的動作或狀態(tài)。過去進(jìn)行時(shí)態(tài)動作先發(fā)生，一般過去時(shí)態(tài)動作后發(fā)生。

a. Mrs. Jones was still cleaning the house when her husband came back from work. She was wearing dirty, old clothes and no stockings; her hair was not tidy； she had dust on her face, and she looked dirty and tired. Her husband looked at her and said, “Is this what I come home to see after a hard day's work?”

瓊斯太太在她丈夫下班回家的時(shí)候仍在打掃房間。她穿一身又臟又舊的衣服，沒穿長筒襪，披頭散發(fā)，滿臉灰塵，顯得又臟又累。丈夫看見她這副模樣就說：“難道我辛苦工作了一天，回到家就為了看你這副模樣嗎？”
