When Sally arrived home, her mother was cleaning the house.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.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。 While Andy was waiting for the bus, he was reading a newspaper. He was cleaning his car while I was cooking.主句和从句的动作在过去的某时刻或某段时间同时发生,而且动作都是持续性的,此时用_引导从句,而且主句和从句都用_时态。总结:when, while 过去进行时1. 概念: 表示过去某个时刻或过去一段时区别: 1. 由when引导的时间状语从句,主句用过去进行时2. 句子结构: 主语 + was/were + doing sth. 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。When the teacher came in, we were talking. 如: 当此句改变主从句的位置时,则为: While we were talking, the teacher came in. 2. 如果从句和主句的动作同时发生,两句都While they were playing basketball, she 用过去进行时的时候,多
