1、#过去进行时（The past Continuous tense）. 过去进行时态表示的是过去某个时间正在进行或发生的动作。其构成形式为：“主语+was/were+现在分词”构成。一般情况下，过去进行时态有一些提示性词语，如at this time yesterday , at that time，或由when引导的时间状语从句。过去进行时态用法简单列举如下： 1.肯定句式。过去进行时态的肯定句式一般体现为：“主语+was/were+现在分词+其他”构成。其中凡是在主语是单数人称情况下一律用was，复数人称情况下用were。如： I was working. We were working.
2、2. 否定句式。过去进行时态的否定句式构成形式为“主语+was/were+ not+现在分词+其他”构成。was/were的用法与肯定句式的用法相似。如： I was not working. We were not working. 3.疑问句式。过去进行时态的疑问句式只需把was/were提前放在句首即可。其构成形式为“was/were+主语+ not+现在分词+其他？”构成。如； Was she working? Were they working? 其简略回答形式用“Yes+主语+动词”或“No+主语+动词+not”。如： Yes, she was . No, she was not.
3、 其中，过去进行时态的现在分词构成规则与现在进行时态的现在分词是相同的。#when和while的用法区别（一）、when，while都有“当时候”的意思。when既可表示某一点时间，也可以表示某一段时间 。在when引导的时间状语从句中，其谓语动词可以是延续性的，也可以是非延续性的，可与主句中的谓语动词同时发生，也可在其后发生。 例如： 1、I was just reading a book when she came into my room. 她走进我房间时，我正在看书。 2、Were you writing when the teacher came in? 老师进来的时候，你在写信吗？
4、 3、When he was a child he was always trying out new ideas. 他小时候就常常试验一些新的设想。 （二）、while只能表示某一段时间，不能表示某一点时间。在while引导的时间状语从句中，其谓语动词只能是延续性的，而且也只能与主句中的谓语动词同时发生或存在。 例如： 1、While Jim was mending his bike, Lin Tao came to see him. 正当吉姆修自行车时，林涛来看他。 2、You cant do your homework while youre watching TV. 你不能一边看电视一
5、边做家庭作业。 （三）、另外，when和while的区别还在于：while引导的时间状语从句多用进行时态，而when引导的时间状语从句多用一般时态。 例如： 1、While they were talking , the bell rang. 正在他们谈话的时候，上课铃响了。 2、I was doing my homework when my mother came back home yesterday evening. 昨天晚上妈妈回家的时候，我正在做家庭作业。一 、单选1 What _ from three to four yesterday afternoon?A have you d
