One pssible versin
when, while
1. 概念: 表示过去某个时刻或过去一段时间正在进行的动作。2. 句子结构: 主语 + was/were + ding sth. + 时间状语3. 时间状语词: at 5:00 yesterday afternn, at that time, then 等连用, 或者用另一动作来表示过去的时间。如：
They were playing basketball when she arrived.While they were playing basketball, she arrived.
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。
过去进行时与一般过去时的区别
1) Shirley ______ a bk abut China last year but I dn’t knw whether she had finished it． A. has written    B. wrte C. had written    D. was writing
2) Mary ____ a dress when she cut her finger. A. made      B. is making 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。
3) He ______ (write) a letter, then went t bed.
wrte 表示动作已结束，做另一件事，如用was writing 就与 went t bed 在逻辑上相矛盾。
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。
He ___________ all night last night. （生动的描写，他一直写……） He ________ smething last night． （说明他写了……的事实）
was writing
注：下列几类动词通常不用过去进行时。 ① 表示状态的动词 be； ② 感官动词：feel, hear, see, smell, taste等; ③ 表示思维或心理状态的动词：believe (认为), frget, cnsider, knw, remember, hpe, wish, want 等； ④ 表示所属关系的动词：belng, have, wn, hld (容纳)等。
区别：1. 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； 由while引导的时间状语从句，主句用一般过去时，从句应用过去进行时。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.
2. 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： They were singing while we were dancing.
1. I _________ my hmewrk when Mike ______ last night.  昨天晚上迈克来的时候我正在写作业。2. While Ann ____________ TV, her father _______ hme.  安正在看电视时，她父亲回来了。
