过去完成时的句子里when怎么用?I had nearly reached the town,when the young man said‘Do you speak English?'When I had fastened my seat belt,the plane took off.这两句里when在不同的位置,是不是在过去完成时的句子里,when放在过去和过去的过去前面都可以?

过去完成时的句子里when怎么用?
I had nearly reached the town,when the young man said‘Do you speak English?'
When I had fastened my seat belt,the plane took off.
这两句里when在不同的位置,是不是在过去完成时的句子里,when放在过去和过去的过去前面都可以?
答
不是,这里的when是“当……时候”的意思,
它所放处的位置跟时态是没有关系的,
