求所有过去时的讲解（比如一般过去时,过去完成时）是所有的

你好!常用过去时态有以下几种： 1,一般过去时 She was a student last year. 为发生在过去的单纯状态. He studied in that school last year. 单纯动作. 2,过去进行时 His father was watching TV when he came back home. 从句动词came为一过性动作,所以用一般过去时,而主句动作在过去一直持续,所以是过去进行时. 3,过去完成时为过去的过去已经发生的事情 He had finished her homework before his sister began to do hers. 他完成作业在先,而且对后来可产生影响,所以用过去完成时.妹妹的动作在后,所以用一般过去时. 4,过去将来时表示在过去某个时间设想、要做和将要发生的事情： She said that she would go to Beijing next year. 希望这些解释对你有所帮助.
