（四） 、过去进行时与一般过去时的区别 过去进行时着重描述当时正在持续进 行的动作，它的特点是：暂时，持续 和未完成，强调过程；一般过去时表 示发生过的动作或存在的状态，即表 示动作发生过，或者已经结束了，强 调事实或结果。 1.She wrote a letter to her friend last night. 她昨晚给她的朋友写了封信（信写完了） 2.She was writing a letter to her friend last night.她昨晚一直在给她的朋友写信。 （信不一定写完）
二、过去进行时与一般过去时的区别 1、过去进行时着重描述当时正在持续进行的动作，它的特点 是：暂时，持续和未完成，强调过程；一般过去时表示发生过 的动作或存在的状态，即表示动作发生过，而且已经结束了， 强调结果。 D 1）Shirley __________ a book about China last year but I don't know whether she had finished it． A．has written B．wrote
C．had written D．was writing
C 2）Mary __________ a dress when she cut her finger．
C．was making D．makes was
making表示正在做衣服的过程，如用made则表示这一动作 已结束，做衣服的动作已结束与cut her finger就没有联系.
wrote 3）He ___________(write) a letter，then went to bed．
wrote表示动作已结束，做另一件事，如用was writing就与went to bed在逻辑上相矛盾。
2、过去进行时侧重表示动作延长的时间长度； 一般过去时表示过去某时发生过某事，侧重说 明事实。 was writing He _____________all night last night（生动的 描写，他一直写……）
wrote He ________ something last night．（说明他写 了……的事实）
