对了 现在我报读的ABC天丅口语的外教和我提到 若想将英语学好是轻松的；必然需要个适合的学习空间跟闇练口语对象，最关键就是外教水平，发音纯正才行，不间断每日口语练习 1 on 1加强化教学才能够有很.好.的进步效率；学习后还要回放复习课后录音反馈，好巩固知识点..实在是真的没有练习对象的话，最好能上 VOA或大耳朵拿到课余学习材料阅读，多问多听一下子语境就加强起来，学习效益是必定达成目标的；1、As my father _was leaving (leave) the house,the postman__arrived___(arrive).
、Tom__was working___(work)in the garden wle I__was sitting___(sit) in the sun.
、As I__was walking___(walk)down the street,I__met___(meet)Charlie.
、Wle he_was reading___(read)the letter,he__heard___(hear)a knock at the door.
、Wle mother__was preparing___(prepare)lunch,Janet__was setting__(set)the table.
