怎样区分过去式和过去进行时
过去式指在过去的一段时间里发生某个动作,而且动作已完成.过去进行时指过去的一段时间里（曾经）正在进行的动作.
如,I was reading a book when he came into the room.
当他进房间时（过去的一段时间）,我正在读书.
He helped his mother (to) do the housework yesterday.
昨天他帮妈妈做家务（过去的一段时间里 已完成动作）
一般句子有 yesterday,a year ago,last week 表过去时间的词语,用过去式.
过去进行时要结合前后句子,根据中文意思判断.
They_________(talk) about it,I didn't want to disturb them
结合后面的句子,我想不打扰他们是因为他们（当时）【正在】讨论XX,所以要用 【were talking】
I was practising the violin at 8 o'clock yesterday evening.
强调的是昨天晚上8点(某个时间点)我正在练习小提琴
I practised the violin yesterday evening.
指昨晚我练习了小提琴
