原文：What had happened to the writer's bag?
After I had had lunch at a village pub,I looked for my bag.I had left it on a chair beside the door and now it wasn't there!As I was looking for it,the landlord came in.
'Did you have a good meal?" he asked.
'Yes,thank you,' I answered,'but I can't pay the bill.I haven't got my bag.'
The landlord smiled and immediately went out.In a few minutes he returned with my bag and gave it back to me.
'I'm very sorry,' he said.'My dog had taken in into the garden.He often does this!'
课文在叙述过去一件事情,这一课讲过去完成时,说过去发生的一前一后的两个事情,前面发生的用现在完成时,后面发生的用过去时,但是In a few minutes he returned with my bag and gave it back to me.很明显,他必须要先拿着包回来,才能把包还给我,应该是前半句过去完成时,后半句过去时才对,而这句话用and就把前后发生的两件事儿给连接了,那么如果这样可以的话,我们是不是可以省事点,以后都用这种句式,而不去折腾过去完成时呢
In a few minutes he returned with my bag and gave it back to me.这句为什么就不用过去完成时呢
