Ⅰ过去进行时：表示在过去某一时间内正在进行的动作。
构成：was / were + 现在分词（其中was是am、is的过去式，were是are的过去式） eg. 1) What were you doing at nine last night?(昨晚9点你在干什么?)
I was doing my homework then . (那时，我正在做作业)
2) He was cooking in the kitchen at 12 o?clock yesterday . (昨天12点，他正在厨房烧饭。) 用法1）过去进行时表现过去某一时刻正在进行的动作。
eg. She was writing a letter when I came in . (我进来时，她正在写封信。) 2）过去进行时还表示过去某阶段正在进行的动作。
eg. They were waiting for you yesterday . (他们昨天一直在等你.) 过去进行时与一般过去时的区别； 过去进行时：表示正在进行的动作。 I was reading a novel last night.昨晚我在看小说。（可能还没有看完） 一般过去时：表示一个完成的动作。 I read a novel last night .昨晚我看了一本小说。（已经看完了） Ⅱ在本单元中，出现了以when和while引导的时间状语从句。
The boy was walking down the street when the UFO landed.(当UFO着陆时男孩正走在街道上.) While the boy was walking down the street, the UFO landed.(当男孩正走在街道上时,UFO着陆了.)
when 和 while 引导的时间状语从句
13
1) 延续性动词和非延续性动词
延续性动词指动作可以延续一段时间，而不是瞬间结束。如：work、study、drink、eat等。 非延续性动词指动作极为短暂，瞬间结束。如：start、begin、arrive、jump、go、 finish、borrow、knock等。
2) when表示“当……的时候”。它后面既可跟延续性动词，又可跟非延续性动词.如：
Mary was having dinner when I saw her .(当我看到玛丽的时候,她正在吃饭.)
主句 从句(see是非延续性动词)
3) while表示“在……的时候”、“在……期间”。While后面必须是表示动作或状态的延续性动词。如：
The weather was fine while we were in Beijing .(当我们在北京的时候天气很好.) 主句 从句(表示状态) She called while I was out .(当我不在时,她打过电话.)
While we were swimming someone stole our clothes .(当我们正在游泳的时候,有人偷了我们的衣服)
从句( swim延续性动词)
所以, when可指时间点，又可指时间段，从句中可用延续性动词，也可用非延续性动词。
while总是指一个时间段，从句中必须用延续性动词。
