英语语法,过去进行时
He fell asleep when he was reading.他看书时睡着了.和We were having supper when the phone rang.我们正在吃晚饭时电话响了.为什么一个过去进行时在when的后面一个在when的前面,不是when 只能引导非延续性动词吗,reading是延续性动词呀

这两句涉及不同的语法现象：
第一句的when表示“当……的时候”.
第二句的when相当于and at that time或 and then,它引导的是并列句.
另外,when引导非延续动词的时候,意思是“一边……一边……”,与这里意思不同.
希望可以帮到你,我也会手留余香的……

英语语法,过去进行时He fell asleep when he was reading.他看书时睡着了.和We wer He fell asleep when he was reading when之后可以接过去进行时吗过去进行时中过去进行时中when与while的区别及用法(最好举例说明)1.He fell asleep ( )he w He was so tired that he fell asleep halfway through reading. John fell asleep _____ he was as she was reading the newspaper,he fell asleep.的意思是 Though the book is ------worth reading,he fell----asleep bec He fell asleep while (he was) doing his homework 英语语法问 With the lights burning,he fell asleep.后半句 He fell asleep while___his exercises. when是引导时间状语重句的,如果主句是过去时从句是过去进行时,那为什么句子是When he was young ,he when是引导时间壮语重句的,如果主句是过去时从句是过去进行时,那为什么句子是When he was young ,he
