B.wroteC.hadwritten

D.waswritingD2)Mary____

adresswhenshecutherfinger.A.made

B.ismakingC.wasmaking

D.makes

wasmaking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cutherfinger就没有联系。C3)He______(write)aletter,thenwenttobed.wrotewrote表示动作已结束，做另一件事，如用waswriting就与wenttobed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___________allnightlastnight.

（生动的描写，他一直写……）He________somethinglastnight．

（说明他写了……的事实）waswritingwrote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),forget,consider,know,remember,hope,wish,want等；④表示所属关系的动词：belong,have,own,hold(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。Whentheteachercamein,weweretalking.

当此句改变主从句的位置时，则为：

Whileweweretalking,theteachercamein.when,while2.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：

Theyweresingingwhileweweredancing.1.I_________myhomeworkwhenMike______lastnight.

昨天晚上迈克来的时候我正在写作业。2.WhileAnn____________TV,herfather_______home.
