Mr Evans was born in Australia.Now he works in Sydney. Last week he had a two-week holiday, but he didn't know where to go. He said to his friend Robert, "I hate the hot weather here, but I can't find a cool place in Australia. Could you tell me where i can go and take my holiday?" "That's easy," answered Robert, "You can go to Moscow. Snow and ice are covering the ground there at this time of year. " Mr Evans thought for moment then he agreed with his friend. He bought a plane ticket and soon got to Moscow. In Moscow He was having a good time there, but one day he got into trouble . After lunch, he went to a park outside the city. He saw a dog following him when he was walking past a house. It seemed that the dog was very hungry and wished some food to eat very much. But Mr Evans didn't have a piece of bread or meat in his pockets. He tried to shoo it away, but it just followed him and it began to bark him. Just at that moment, he saw a stone on the ground. So he stopped and tried to pick it up, but he couldn't (填词)it out. " How strange these Russians are!" Mr Evans stopped pulling it and said to himself, "They do not tie their dogs, but firmly tie the stones "
