Question: Article: One of the most successful singers of the twentieth century, Ella Fitzgerald has made several different styles of her own. She was born in Virginia but was brought up in an orphanage in Yonkers, New York. Chick Webb _ her in an amateur competition when she was sixteen. He engaged her to sing with his band and when he died in 1939, she took over. Unlike Bessie Smith, Ella Fitzgerald taught herself the sentimental music so popular in the 1930's -- songs like "My Heart Belongs to Daddy"-- and her recordings became best-sellers. During the 1940's she developed her own "scat singing" -- a breathless, nonsense--syllable style--for songs like "Flying Home" and "Lady Be Good." Ella Fitzgerald was the perfect musical partner for her friend, the trumpeter Louis Armstrong, matching him in warmth and artistry. "I just like music, period," she said. "To me, it's a story. There's only one thing better than singing.... It's more singing."
Answer: The musical career of Ella Fitzgerald.

Answer: What does the passage mainly discuss?

Question: Article: When I was 16 years old, a boy gave me an important gift. It was a smile. It was the early autumn of my first year at a junior high school, and my old school was far away. As a result, no one knew who I was. I was very lonely, and afraid to make friends with anyone. Every time I heard the other students talking and laughing, I felt my heart break. I couldn't talk about anyone with my problems. And I didn't want my parents to worry about me. Then one day, my classmates talked happily with their friends, but I sat at my desk unhappily as usual. At that moment, a boy entered the classroom. I didn't know who he was. He passed me and then turned back. He looked at me, without a word, a smile. Suddenly, I felt the touch of something bright and friendly. It made me feel happy, lively and warm. That smile changed my life. I started to talk with other students and made friends. Day by day, I became closer to everyone in my class. The boy with the lucky smile has become my best friend now. One day I asked him why he smiled, but he couldn't remember smiling at me!It doesn't matter because all the dark days have gone. I believe that the world is what you think it is. If you think it lonely, you might always be alone. So smile at world and it will smile back.
