    When I was four years old I got ill. I took medicine twice a day. The medicine had so a bitter taste that I took it mixed in
orange juice. The problem was that I can't still taste the medicine.
In a particular afternoon my mother brought the drink in. As
she gave it to me, the phone rang and she go to answer
it. I looked at the orange drink and decided I couldn't face them,
so I hid the glass behind a pile magazines. Of course, when
my mother was asked, "Have you already taken your medicine?"
I said, "Yes." I felt very pleased with me. The next day, my
mother found drink when she was doing the housework. She
looked at me serious and said, "It's bad to tell lies !"

    Music comes in many forms; most countries have a style of their own. The US is well known for jazz (爵士乐), which has gained world-wide popularity.

    In contrast to classical (古典的) music, which follows formal European traditions, jazz is natural and free-form. It is full of energy, expressing the moods, interests, and feelings of the people. It has a modern sound that makes people very excited. In the 1920s jazz sounded like America. And so it does today.

    The origins of this music are as interesting as the music itself. Jazz was produced by American blacks, who were brought to the Southern States as slaves. They were sold to plantation owners (种植园主) and forced to work long hours in the cotton and tobacco fields. This work was hard and life was short. When a Negro died, his friends and relatives formed a group to carry the body to the cemetery.

    A band often went with them. On the way to the cemetery the band played slow and sad music. But on the way home the mood changed. Spirits lifted. Everybody was happy. Death had removed one of their members, but the living were glad to be alive. The band played happy music, which made everyone want to dance. It was an early form of jazz.

    Music has always been important in their lives. Coming mainly from West Africa, the black men who were brought to America already possessed a rich musical tradition. This music centered on religious ceremonies (宗教的仪式) in which dancing, singing, clapping and stamping (顿足) to the beat of a drum were important forms of musical expression. As these people settled in to their fields, they made up work songs. Singing made the hard work go faster.

    Another musical form that helped to develop jazz was the blues. Blues songs always describe something sad — an unhappy love affair, a money problem, bad luck. To this day, the expression "feeling blue" means being sad.

    Country music is one of the most popular kinds of music in the United States today because it is about simple but strong human feelings and events-love, sadness, good times, and bad times. It tells real-life stories and sounds the way people really talk, as life becomes more complicated (复杂的) it is good to hear music about ordinary people.

    Country music, sometimes called country-western, comes from two lands of music. One is the traditional music of the people in. the Appalachian Mountains in the eastern United States. The other is traditional cowboy music from the west. The singers usually play guitars, and in the 1920s they started using electric guitars.

    At first city people said country music was low class. It was popular mostly in the South. But during World War II, thousands of Southerners went to the northeast and Midwest to work in the factories. They took their music with them. Soldiers from the rest of the country went to army camps in the South. They learned country music. Slowly it became popular all over the country.

    Today country music is also popular everywhere in the United States and Canada-in small towns and in New York City, among black and white, and among educated and uneducated people. About 1,200 radio stations broadcast country music twenty-four hours day, English stars sing it in British English, and people in other countries sing it in their own languages. The music that started with cowboys and poor southerners is now popular all over the world.

    Americans have contributed to many art forms, but Jazz a type of music, is one that was not started in the United States. Blacks, who sang and played the music of their homeland, created jazz.

    Jazz is a mixture of the music of Africa, the work songs the slaves sang and religious(宗教的) music. Improvisation is an important part of jazz. This means that musicians make the music up as they go along, or create the music on the spot. This is why a jazz song might sound a little different each time it is played

    Jazz bands formed in the late 1800s. They played in bars and clubs in many towns and cities of the South, especially in New Orleans. New Orleans is an international seaport, and people from all over the world came to New Orleans to hear jazz.

    Jazz became more and more popular. By the 1920s, jazz was popular all over the United States. By the 1940s, you could hear jazz not only in clubs and bars, But in concert halls as well. Today, people from all over the world play jazz. Jazz musicians from the United States, Asia, Africa, South America, and Europe meet and share their music at festivals on every continent. In this way jazz continues to grow and change.

    During this time, in the 9 1940s and early 1950s, city people became wealthier. They had more children. They needed more  10. They moved out their flats in the city to buy their own houses. They bought houses in the 11 , areas near a city where people live. These are areas without many offices or factories. During the 1950s the American "dream" was to have a house on the outskirts.

— That's all right.
