当主语是第一人称单数形式或第三人称单数形式时，
be动词用was，其余人称用were。
过去进行时
过去进行时 (The Past Progressive Tense)
基本用法
过去进行时表示在过去某个确定的时间点或某一段时间里正在发生的动作。因此，原则上，常和表示过去的时间状语连用，如：then, at / that time, yesterday, last night。
e.g. What were you doing at nine last night

否定句：主语 + be (am / is / are) + not + 现在分词 + 其他
e.g. We aren’t enjoying our trip.

一般疑问句：Be (Was / Were) + 主语 + 现在分词 + 其他？
e.g. — Is she still studying abroad
— Yes, she is. / No, she isn’t.
— Look! Is the bird flying in the sky
— Yes, it is. / No, it isn’t.
特殊疑问句：疑问词 + be (was / were) + 主语 + 现在分词 + 其他？
e.g. — What was he doing at the time of the fire yesterday
— He was studying at the library then.

过去进行时的基本用法
eg：I was watching TV the whole night.

eg：Miss Li was shopping at this time yesterday.
I was looking for my lost cat at nine last Monday morning.
表示过去某一时刻正在进行或发生的动作，与表示过去某一时间点的时间状语连用，如at 3 o'clock yesterday afternoon, at this time yesterday等。
