单选题 The dog, called Prince, was a smart animal and a slave to Williams. From morning till night, when Williams was at home, Prince never left his sight, ignoring all other members of the family. The dog had a number of duties, for which Williams had patiently trained him. As a good pupil, he lived for chances to demonstrate his abilities.
When Williams wanted to put on his boots, he would murmur "Boots". Within seconds the dog would drop them at his feet. At nine every morning, Prince ran off to the general store in the village, returning shortly not only with Williams' daily paper but with a half ounce packet of Williams' favorite tobacco. As a gundog by breed, Prince possessed a large soft mouth which specially evolved to carry hunted creatures safely. Therefore, there was never a tooth mark on the paper and the tobacco.
Williams was a railway man, an engine driver, and he wore a blue uniform which smelled of oil and oil fuel. He had to work at strange times—"days", "late days" or "nights". Over the years Prince got to know these periods of work and rest, knew when his master would leave the house and return, and the dog did not waste this knowledge, If Williams overslept, as he often did, Prince barked at the bedroom door until he woke, much to the trouble of the family. On his return, Williams' slippers (拖鞋) were brought to him.
A curious thing happened to Williams last winter. One evening he fell on the icy road somewhere between the village and his home. He was so badly hurt that he stayed in bed for three days; and not until he got up and dressed again did he discover that he had lost his wallet that contained over fifty pounds. The house was turned upside down in the search, but the wallet was not found. However, two days later Prince dropped the wallet into William's hand. Very dirty and wet through, it still contained fifty three pounds, Williams' driving license and a few other papers. No one could tell where the dog had found it, but he had found it and recognized it probably by the faint oily smell on the leather.
