No,you/we/theywerenot.注：1)wasnot常缩略为wasn’t;werenot常缩略为weren’t。2)一般过去时与过去进行时用法的比较:一般过去时表示在过去某个时间发生过的动作或存在的状态,而过去进行时则表示在过去某一时刻或某一段时间正在进行的动作。例如:Davidwrotealettertohisfriendlastnight.大卫昨晚给他的朋友写了封信。(信写完了。)Davidwaswritingalettertohisfriendlastnight.大卫昨晚一直在给他的朋友写信。(信不一定写完。)Practice:Lookatthepictureandmakeupthedialogues.Step7Exercises.1、用所给词的正确形式填空（1）.What______(be)you______(do)whenhearrived?（2）.Jim_____________(sleep)whenIcamein.（3）.They_____________(watch)TVat8:00yesterdayevening.（4）.Nowhe__________(read)and_________(write).Step8Homework1.Rememberthewordsandphrasesinthislesson.2.Finishtheexercisesintheworkbook教学反思：本课是本单元的第一课时，我主要是让学生复习旧知现在进行时的基础上，去对比学习新知识过去进行时，重在让学生在操练重掌握并熟悉新知识。大多数学生能理解并熟练运用过去进行时这一语法，但对于基础教差的学生还得加强训练。
