我个人觉得是房子92年被修建97年重修2002年一家人搬走了···这样算下来,The house is ------ years old?
不应该是about 97 ?我看正确答案选的是over 100 !希望听听大家的想法·~~~~四处关于时间的段落都加粗了
We moved into a beautiful two-storied old house. The house was built in 1905. It was repaired in 1997.
At first, really small things began to happen that didn't make me believe that anything was wrong, but as time went on, the things started becoming stranger and stranger. Early on, something would turn up missing, and later would be found somewhere else. I just thought I had forgotten where I put it, or perhaps my daughter was playing around with things. Then later on I would hear strange sounds when nobody was at home but me... yet it was an old home, and sometimes old homes did make little noises, so again, I don’t really mind.
Then things that I couldn’t explain started happening. It was last November and I was at home alone cleaning house. When I was sweeping the kitchen floor, I felt a very cold wind blew my hair. I thought the kitchen window must have been opened, but when I checked it, it was closed and locked. The windows were new, and there was no way any cold air came in.
We all felt very strange and moved away from there in October 2002. I was never really frightened. It was just strange, like something or someone was trying to reach out and get my attention or something.
