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.

Article: While I was waiting to enter university,I saw advertised in a local newspaper a teaching post at a school in a suburb of London about ten miles from where I lived. Being very short of money, I applied. Three days later, a letter arrived, asking me to go to Croydon for an interview. It proved a tiring journey: a train to Croydon station; a ten-minute bus ride and then a walk of at least fifteen minutes. It was clearly the headmaster himself that opened the door. He was short and fat, with a grey-color1ed moustache,a deeply lined face and hardly any hair. He looked at me with surprised disapproval. Then he said. "You'd better come inside." Leading me into his study, he started to ask me a number of questions: what subjects I had taken in my General School Certificate;how old I was; what games I played; whether I thought games were an important part of a boy's education, etc. I said something about not attaching too much importance to them. We obviously had very little in common. The teaching arrangement filled me with fear. I was to divide the class of twenty-four boys, aged from seven to thirteen, into three groups and teach them all subjects--including art, football, cricket and so on--in turn at three different levels. Actually, I was depressed at the thought of teaching algebra and geometry--two subjects in which I had been rather weak at school. I said shyly, "What would my salary be?" "Twelve pounds a week plus lunch." Before I could speak, he got to his feet. "Now," he said, "you'd better meet my wife. She's the one who really runs this school." This was the last thing I could hear. I was young. How could my dignity allow me to work under an old woman?
Answer: Because he wanted to earn some money.

Article: On April 24th, another natural disaster-the oil spill in the Gulf of Mexico, happened. Millions of dollars have been used to help stop the spill and to clean up the animals, beaches, and land spoiled by the oil. Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea. But governments seem to accept the _ of transporting mil-lions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage. Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run. Of all of today's environmental disasters, an oil spill may actually be one of the least serious. Although oil is poisonous, it is a natural material. In the end, it breaks down naturally. In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tons of oil into the ocean. If you go there today, you will find it hard to see any sign that it ever happened. However, we should be thinking more about reducing our dependency on oil. Governments should be encouraging research into new technologies, such as cars run by solar power, electricity, hydro-gen, and so on. Much of this research, in the past, was stopped by the oil, gas, and coal. If the world's millions of cars were 10% more efficient ,we would need many fewer tankers crossing the oceans each year. If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too.
Answer: Oil spills pollution.
