She Lived in Paris.As she was a child.as有“一边一边”的意思He sang as he walked.“when”When the clock struck twelve, all the lights went out.I was sleeping when she came in. 动补When we arrived at the station, the train had left.“while” 主、从句动作或状态同时发生。用while引导的从句用延续性动词，常表示较长的时间或一个过程。While we were having supper, all the lights went out.Please keep quiet while others are studying.While I was writing letters last night, he was watching TV. when, while并列连问。when和while都可用作并列连问，连接并列分句。When表示“就在的时候”, while意反而，可是，表示转折。One evening Beethoven was walking in a street, when he suddenly stopped outside a little house.并列连词引导并列句，意思是就在那时。（三）、主句是一般将来时，时间状语从句用一般现在时表将来，主句是过去将来时，从句用一般过去时表示过去将来时，主句是一般过去时，从句用一般过去时。1.
