Born in Edinburgh, Scotland, Bell grew up in a family that was very interested in teaching people to speak. His grandfather had been an actor who left the theatre to teach elocution(演讲技巧); his father was a teacher 38 deaf-mutes learn how to speak.
However, probably none of the later inventions gave Bell the same feeling of success __39_ he had on the day when he spilled some acid from his batteries. It was after he had worked for months to find ways to send something more than metallic twangs(金属砰弦声)over the wires. Thinking Watson, __40__, was in the next room, Bell called, "Mr. Watson, come here. I want you." Watson was not in the next room. He was down in his laboratory, next to the receiver. To Watson's surprise, he heard the words perfectly. He ran to tell Bell the news: the wires had carried Bell's voice perfectly.
