时态详解：过去进行时

时态详解：过去进行时一、过去进行时的定义过去进行时主要表示过去某一时刻正在进行的动作，或表示过去某一阶段一直在进行的动作。如： I was having a talk with Li Hua at that time. 那时，我正在跟李华谈话。 I was watching TV at home last night. 昨晚我一直在看电视。二、如何理解过去进行时：大家知道，过去进行时表示说话时正在进行的动作或发生的情况。由此可推知，过去进行时就是表示在过去某时正在进行的动作或发生的情况。如汉语说“我进来时他正在吃饭”，如果“进来”发生在过去，那么“正在吃饭”显然就是过去某时正在进行的动作——也就是说，“进来”用一般过去时，“正在吃饭”就要用过去进行时。三、过去进行的构成过去进行时由“was / were + 现在分词”构成。如： Someone is knocking the door. 有人在敲门。 Steam was rising from the coffee. 咖啡冒着热气。 Clouds were flying across the sky. 云彩飘过天空。注意有些was (were) doing sth不是现在进行时，而是系表结构，其中的doing sth是动名词，不是现在分词。如： Her job was washing clothes. 她的工作是洗衣裳。 Her hobby was growing roses. 她的爱好是种植玫瑰。 Her suggestion was having our conversation in French. 她的建议是我们用法语交谈。四、过去进行时的主要用法 1. 表示在过去某一点时间或某一段时正在进行的动作。如： I was having a bath when the phone rang. 我正在洗澡，突然电话铃响了。 She was writing letters. I didn’t want to disturb her.她在写信。我不想打扰她。 2. 表示在过去短期内正在进行的动作或存在的情况，这种情况通常不会长期如此。如：
