There was a professor who worked in a university in Tokyo. He had a dog. He was very kind to his dog, and the dog loved the master very much. Every morning the professor went to walk with his dog. Of course, the dog could not go with the professor to the university. It followed him only as __far__ as the railway station where it watched him buy his ticket and disappeared in the direction of the train. Then the dog would sit at a small square in front of the station, waiting for its master's return. After one year, passers-by were very __familiar__ with the dog and all praised it for its loyalty.One afternoon, the professor had a sudden heart attack and died at work, but the dog still sat at the same place waiting. In the evening several persons thought about the dog and went to see __if__ it was still there. It seemed that the dog could understand them when they said to it, “Go home, poor thing. Your master will never come to you again”.Weeks became months, months became years, and still the dog waited there. People were really moved by this sight. A famous artist made a statue of the dog and placed it at the very place. From then on, the dog sat in the __shade__ of its own statue to wait for its master.The years passed. One day, the dog died, but people there could not forget that dog. Its statue has become a well-known spot. If someone asked, “__where__ shall we meet at the station?” Another would always answer, “At the statue of the dog.”
