when, while, as的比较

来源:www.6v3c.com 2025-02-13

老师好!2020年的全国卷,65题:  65   he asked the villagers on the banks of the river where he could find the legendary artist, they smiled and pointed down the river. 答案是When/As。

我读了http://www.yygrammar.com/Article/200802/154.html关于when、while、as有什么区别,有的迷糊。假设这个人问完后,村民笑了,那样此时只可以用when。但答案有as,那应该是在问的过程中,村民就笑了,那ask就是延续性动作,smile和point是非延续的,主短从长,那这个时候答案为何没while呢?while也有连接一般体的状况

 

从句的asked, 包含主句的smiled 和 pointed 都用了一般过去时,说明这三个动作都已经先后发生,且不延续。故用when或 as,由于这两个连词引导的从句,谓语动词都可以是非延续性动词。过去时的 asked 表示终止,非延续,when 和 as 都表示 “问完后”。对于while 就不可以了,谓语动词需要延续,除非把它改为过去进行时。

 When/As he asked the villagers on the banks of the river where he could find the legendary artist, they smiled and pointed down the river. (问完后)

 While he was asking the villagers on the banks of the river where he could find the legendary artist, they smiled and pointed down the river. (询问中)
