Past Perfect Simple (过去完成时)

Form of Past Perfect Simple:

For irregular verbs,use the past participle form .For regular verbs,just add ed.

(putting emphasis only on the fact,not the duration)

Past Progressive (Past Continuous) (过去式进行)

以上,我将三种不同时态:过去完成时,过去式进行时和过去式 都用英文作了解释,并提供了用法,每一种用法下面还附了例句,我想,一看就会很清楚了~
说白了,过去完成时是不能单独用的,比如有两件事A和B,都发生在过去,但A发生在B以前,那麼A用过去完成式,而B则用过去式.
过去式就是单纯地指过去所发生的事.
而过去进行也是很少单独使用的,常和另一个句子使用,有两件事A和B,都发生在过去,但A和B同时发生,那麼其中A(或B) 用过去进行,而B(或A)则用过去式.
很简单吧~^^
