单选题Ann Curry is a famous news presenter of the NBC News "Today" show. When she was 15 she happened to walk into a bookstore in her hometown and began looking at the books on the shelves. The man behind the counter, Mac McCarley, asked if she'd like a job. She needed to start saving for college, so she said yes. Ann worked after school and during summer vacations, and the job helped pay for her first year of college. During college she would do many other jobs: she served coffee in the student union, was a hotel maid and even made maps for the US Forest Service. But selling books was one of the most satisfying jobs. One day a woman came into the bookstore and asked Arm for books on cancer (癌症). The woman seemed anxious. Ann showed her practically everything they had and found other books they could order. The woman left the store less worried, and Arm has always remembered the pride she felt in having helped her customer. Years later, as a television reporter in Los Angeles, Ann heard about a child who was born with problems with his fingers and his hand. His family could not afford a surgical(外科的) operation, and the boy lived in shame, hiding his hand in his pocket all the time. Ann persuaded her boss to let her do the story. After the story was broadcast, a doctor and a nurse called, offering to perform the surgical operation for free. Ann visited the boy in the recovery room after the operation. The first thing he did was to hold up his repaired hand and say, "Thank you. " What a sweet sense of satisfaction Ann Curry felt! At McCarley's bookstore, Ann always sensed she was working for the customers, not the store. Today it's the same. NBC News pays her, but she feels as if she works for the people who watch the programmes, helping them make sense of the world.

David's firm releases two new games for the fast growing computer market each month. But David's biggest headache is what to do with his money.
