The boy was still sleeping when his mother got home yesterday morning . I was walking to school when I saw a cat in a tree.When Sally arrived home, her mother was cleaning the house.点拨：主句的动作是持续性的，而从句动作是短暂性的，此时用 _ 引导时间状语从句，主句用 _ 时态，从句用一般过去时态。 While I was sleeping in the bedroom, someone knocked at the door. David fell while he was riding his bike.点拨：主句的动作是短暂性的，从句的动作是持续性的，此时用 _ 引导从句，主句用 _ 时态，从句用过去进行时态。总结：1) when可指时间点, 又可指时间段, 从句中可用延续性动词, 也可用非延续性动词。2) while总是指一个时间段, 从句中必须用延续性动词。3复习过去进行时：(1) Show the pictures with PPT and let the Ss make conversations about what the people were doing.
