A strange thing happened to me last Sunday. It was such a beautiful day that I decided to go for a 1 in the country. On the way back home，my car stopped. It was out of 2 on a lonely road far from a town. I decided to walk until I found someone who could 3 me a gallon（加仑） or two of petrol. I had 4 almost a mile before I finally found a big house near the road. I was 5 to see it because it was starting to get dark. I 6 at the door and a little old lady with long white hair answered. She said, “I have been 7 for you a long time. Come in. Tea is almost ready.”
“But I only came for some petrol.” I answered. I couldn’t 8 what she was talking about.
“Oh, Alfred! Petrol? You used to 9 tea.”
I quickly 10 that I needed some petrol, but she didn’t seem to hear me. She just kept calling me Alfred and talking about how long it had been since she had seen me. She was acting very strangely and I was 11 to leave. As soon as she went to get tea, I went out of the house as fast as I could. 12 , there was another house down the road and I was able to buy several gallons of petrol. When I told the man about my 13. He said,“Oh, that is Miss Emily. She lives by herself in that big house. She’s 14 but she wouldn’t hurt anyone. She is still waiting for the man she was supposed to marry thirty years ago. The day before their 15 he left home and never came back because of the war.”
