     Gloria is a famous hostess of a TV station. 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, John Smith,

asked if she'd like a job. She needed to start saving for college, so she said yes.

     Gloria 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

cleaner and even made maps for the Forest Service. But selling books was one of the most satisfying jobs.

     One day a woman came into the bookstore and asked Gloria for books on cancer. The woman seemed

anxious. Gloria showed her practically everything they had and found other books they could order. The

woman left the store less worried, and Gloria has always remembered the pride (自豪) she felt in having

helped her customer (顾客).

     Years later, as a television hostess, Gloria heard about a child who was born with problems with his

fingers and hand. His family could not afford an operation, and the boy lived in shame, hiding his hand in

his pocket all the time.

     Gloria persuaded (说服) her boss to agree to let her do the story. After the story was broadcast, some

doctors called, offering to perform the operation for free.

     Gloria visited the boy in the hospital 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 Gloria felt!

     At Smith's bookstore, Gloria always realized she was working for the customers, not the store. Today

it's the same. The TV station pays her, but she feels that she should work for the people who watch the

programmes, helping them understand the world better.
