     Dick lived in England. One day in January he said to his wife, "I'm going to fly to New York next

week because I've got some work there." "Where are you going to stay there?" his wife asked. "I don't

know yet." Dick answered. "Please send me your address from there in a telegram (电报)," his wife

said. "All

right," Dick answered.

said, "Now I'm going back to my hotel and have a nice dinner."

remember the name and address of his hotel.
