过去进行时
过去进行时主要表示过去某个时刻或某段时间正在进行的动作。过去进行时和一般过去时经常同在一个句子里使用。过去进行时表示过去正在进行的动作或情况，一般过去时则表示比较短暂的动作或事件。正在进行中的动作或情况往往由连词 when, while, as等引导。
While/ When/ As I was sweeping the floor, I found your pen. 我扫地的时候，发现了你的钢笔。
构成形式：
肯定式
I was working.
We (You, They)用were：We were working.
否定式
I was not working.
We (You, They)用were：We were not working.
疑问式
Was I working
We (You, They)用were：Were we working
when，while 当……时候（强调动作同时发生）
while+从句, 动词一定是延续性动词
when+延续性动词/瞬间动词
while通常只引导持续时间较长的动作，并且主句和从句可以同时用过去进行时，而when一般不这么用：

当他的妻子和一位邻居在电话中聊天时，约翰一直在看电视。
Some students were dancing and singing while others were eating and drinking. 有些学生在唱歌跳舞，而另一些则在吃喝。
