when引导的时间状语从句 when意为“当……的时候”、“在……时候”,引导时间状语从句,表示主句的动作和从句的动作同时或先后发生。 例句: When she is on holiday, she always goes sailing. When I was wandering in the street,I met her. when从句可在主句后,或主句前;在主句前时,要用逗号。 2)when引导的时间状语从句中的动词可以用延续性的=动词,也可以用终止性动词 例句: He was listening to the music when I went in. We will stop when you do. 3)表示事情发生在同个时间段 例句: They went skiing when they were on vacation. 4) 表示从句动作完成之后,紧接着发生其动作 When the bell rang, Tom went out of the classroom. 注:时间状语从句在表示将来之时,常用一般现在时表将来 例句:I will go to bed when my father comes home. While与when有时候意思相近,因此when有时候可替换while 例如: You called me when (while) I was out. 本文来源:https://www.wddqw.com/doc/939b22b6561810a6f524ccbff121dd36a32dc4a3.html
