解题思路: when  和 while 有什么区别
解题过程:
(一)、when,while都有“当……时候”的意思。when既可表示某一点时间,也可以表示某一段时间 。在when引导的时间状语从句中,其谓语动词可以是延续性的,也可以是非延续性的,可与主句中的谓语动词同时发生,也可在其后发生。 例如: 1、I was just reading a book when she came into my room. 她走进我房间时,我正在看书。 2、Were you writing when the teacher came in? 老师进来的时候,你在写信吗? 3、When he was a child he was always trying out new ideas. 他小时候就常常试验一些新的设想。 (二)、while只能表示某一段时间,不能表示某一点时间。在while引导的时间状语从句中,其谓语动词只能是延续性的,而且也只能与主句中的谓语动词同时发生或存在。 例如: 1、While Jim was mending his bike, Lin Tao came to see him. 正当吉姆修自行车时,林涛来看他。 2、You can’t do your homework while you’re watching TV. 你不能一边看电视一边做家庭作业。 (三)、另外,when和while的区别还在于:while引导的时间状语从句多用进行时态,而when引导的时间状语从句多用一般时态。 例如: 1、While they were talking , the bell rang. 正在他们谈话的时候,上课铃响了。 2、I was doing my homework when my mother came back home yesterday evening. 昨天晚上妈妈回家的时候,我正在做家庭作业.
