If I hadn't had lunch at a village pub, I wouldn't have looked for my bag. 与过去情况相反 的虚拟语气
If I hadn't left it on a chair beside the door ,now it would be there! 错综虚拟语气
If I hadn't looked for it, the landlord wouldn't have come in. 同第一句
下面的就不用改了
'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!'
