過去式、過去進行式、過去完成式　有咩分別+點用?

過去式 : i ate apple
用在書寫普通已經過佐的事情上, 通常單一句子後面會有時間說明,
如: i ate an apple last night
They lived in that house last year.(現在已經沒在住了 ,重點在於時間 :舊年)

過去進行式 : i was eating apple
用在表示在過去進行著一件事時, 有另一件事同時在那時候發生..
如: i was eating an apple when the phone rang.
i was jogging in the park when i saw him yesterday.
They were living at that house in 1990.(在1990年時,住在那間屋)

過去完成式 : i had eaten an apple.
用來表示意件在過去已經完成了的事
如: i had eaten the apple before i knew it was brought by Alice.
i had finished my works before the dead line.
They had been living in that house for 5 years.
(現在已經沒在住了, 重點在於動作: : 住了5年)
