8、He smoked a lot two years ago. （过去行为）b) Would 用于文中不用于句首，只表过去习惯。Used to 表今昔对比的含义，叙述习惯动作可与would 换用。When he was a boy , he would often go there . （叙述过去）She isnt what she used to be. (今昔对比)c) 表示状态时一般只用used toTom used to be fat /There used to stand a tree there. (状态)d) was (were) used to +ving表示“合适于，适应于.

11、ed some letters last night. 我昨晚打了一些信(已经打完) A. 过去进行时却表示动作在持续或未完成，而一般过时往往表示某一动作已经完成。I was reading the book at that time. (未读完，“读”的片段)I read the book yesterday. (已读完，表整个“读”)B、一般过去时表示只做一次动作，而过去进行时却表示动作反复地进行。 She waved to me. 她朝我挥了挥手。 It was raining all night.(优先用was raining ,rained 为持续动词，故也可使用)He was wr
12、iting a letter the whole of afternoon. (短暂动词与持续时间连用，表反复，连续发生，不可用一般过去时)when 和while的用法区别 两者的区别如下： when是at or during the time that, 既指时间点，也可指一段时间； while是during the time that，只指一段时间，因此when引导的时间状语从句中的动词可以是终止性动词，也可以是延续性动词，而while从句中的动词必须是延续性动词。 when 说明从句的动作和主句的动作可以是同时，也可以是先后发生；while 则强调主句的动作在从句动作的发生的过程中或主从
13、句两个动作同时发生。 由when引导的时间状语从句，主句用过去进行时，从句应用一般过去时；如果从句和主句的动作同时发生，两句都用过去进行时的时候，多用while引导，如： a. When the teacher came in, we were talking. 当此句改变主从句的位置时，则为： While we were talking, the teacher came in. b They were singing while we were dancing.过去进行时练习题三、 选择题。1.
