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。 Practice: 汉译英。4a. Look at the table and write sentences with both while and when.
