过去进行时
　　1）过去进行时的构成： was / were +v-ing
　　2) 过去进行时的用法：
　　 过去某一阶段或某一时刻正在进行的动作。 例如：
　　 This time last year I was living in Brazil.
　　 What were you doing at 10 o'clock last night?
　　3)常用于过去进行时的时间状语：
　　 at four yesterday afternoon，then，at that time/moment 等。
　　例题解析：举一反三，学的更轻松！
　　Daddy promised me he ______ me a computer
　　A. was bought B. had bought C bought D. would buy
　　解析："爸爸答应我给我买一台电脑"。宾语从句中的动作是以过去为起点将要发生的动作，应用过去将来时。
　　选D。
　　They said they ______ do some sports if it was fine.
　　A. were going to B. went C. would going D. were going
　　解析："他们说如果天气好的话他们打算去运动。"去做运动发生在说话之后，所以应选用过去将来时，答案B不合适，"打算作某事"为"be going to do ".would 后面应跟动词原形，应选A.
