沪教英语（五四学制）七下Unit5语法讲解及习题 过去进行时（Past continuous） 一、语法知识点详解 1. 定义与功能 过去进行时表示过去某一时刻或某一段时间内正在进行的动作，这与本单元“野生动物”的主题高度契合，常用来生动描述过去某个瞬间野生动物的行为或当时人们正在进行的活动。 2. 构成结构 肯定句：主语 + was/were + 动词的现在分词 (doing) 否定句：主语 + was/were + not + 动词的现在分词 (doing) 疑问句：Was/Were + 主语 + 动词的现在分词 (doing)? 特殊疑问句：疑问词 + was/were + 主语 + 动词的现在分词 (doing)? 3. 用法场景 描述过去某一时刻正在进行的动作 常与表示过去时间点的词连用，如 at 9 o'clock yesterday, this time last week。 例：At 3 p.m. yesterday, we were watching the birds by the lake. 描述过去某一段时间内正在进行的动作 常与表示过去时间段的词连用，如 from 8 to 10 last night。 例：They were feeding the giraffes from 2 to 3 p.m. 两个过去动作同时进行 用 while 连接，长动作用过去进行时，短动作用一般过去时。 例：While the mother swan was sitting on her eggs, the father was keeping watch. 表示过去一个动作发生时，另一个动作正在进行 用 when 连接，长动作用过去进行时，短动作用一般过去时。 例：I was taking photos when a bird suddenly flew away. 4. 现在分词变化规则 一般情况：直接在动词后加-ing → watch → watching 以不发音的e结尾：去e加-ing → move → moving 以重读闭音节结尾且末尾只有一个辅音字母：双写辅音字母再加-ing → sit → sitting 二、练习题 用所给动词的正确形式填空 1.
