时间状语从句:
连接时间状语从句的连接词有:
(1) 连词：when,while,as.它们都表示当…时候的意思.如果主句和从句的动作同时发生且都是进行时
态,只用while,as.其他情况下when,while,as通用.
1 When he came in,I was listening to the radio．
2 As I was wandering in the street,I met her.
3 While (as) I was watching TV,my mum was cooking in the kitchen.
(2) 连词before,after,since,until(till).当他们表示时间时,他们既是介词又是连词.
{ He usually drinks a cup of tea before he goes to school.
连词
