Mr Evans 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 think of a cool place in
Australia. Where shall I take my holiday?"
"That's easy," said Robert, "You can go to Moscow. Snow and ice are covering the ground there
now."
Mr Evans agreed with his friend. He bought a plane ticket and soon arrived in Moscow. He was
having a good time there, but one day he got into trouble (麻烦). After lunch, he went to a park outside
the city. He noticed a dog following him when he was walking past a house. It was hungry and wanted
some food to eat. But Mr Evans had no food in his pockets. He tried to shoo (以嘘声吓走) it away, but
it began to bark at him. Just at that moment, he saw a stone on the ground. He tried to pick it up, but he
couldn't.
"How strange these Russians are!" Mr Evans said to himself, "They do not tie up (栓住) their dogs,
but firmly (牢牢地) tie down the stones!"
