　　Twenty years ago I worked in a middle school．There I taught my students physics．I had studied well and learned a lot by then．I explained the lessons clearly, so they liked my classes．

　　Soon the school years was over．I couldn't decide where to spend my summer holiday．Just at that moment I heard from my father．In his letter he said he had a cousin in Tennessee and it would be his fiftieth birthday the next month．He told me to take part in his birthday party instead of him．I hadn't been to the place before and hoped to see the uncle．And I set out at once．

　　I got off the train at a small station．A carriage(马车)took me right to his farm．His manor(庄园)lay in the middle of the large and wide farm, between a river and a forest and I decided to take my holiday there．My uncle and aunt received me at the gate．He looked strong and introduced his children to me．They were all friendly to me．After a nice dinner he showed me around his manor．It was built two hundred years ago and there were a lot of rooms in it．Most were locked and I couldn't see inside．I had a good sleep that night．

　　The following day a lot of guests(客人)came and my uncle was happy and busy．I heard someone said there was a ghost(鬼)in my room, while I was reading in it that evening．I looked around and seemed to find something strange．I rushed out at once and met a servant(仆人)outside．

　　“Did anything happen in my room?”

　　“Nothing happened ten years ago, madam．”

　　“And what about these ten years?”

　　“Sorry, I don't know．Nobody lived there by yesterday!”
