The U.S.A.is known for jazz,the type of music that has gained worldwide popularity. Jazz is an American contribution to popular music. While classical music follows formal European tradition,jazz is rather a free form. It is full of energy,expressing the moods,interests,and emotions of the people. It is breaking and exciting with a modern sound. In the 1920s jazz sounded like America. And so it does today. The origins of the music are as interesting as the music itself. Jazz was invented by American Negroes,or blacks,as they are called today,who were brought to the southern states as slaves. They were sold to farm owners 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 s would gather and carry the body to have a ceremony before they buried him. There was always a band with them. On the way to the ceremony the band played slowly,solemn music suitable for the situation. But on the way home the mood changed. Spirits lifted. Everyone was happy. Death had removed one of their members,but the living were glad to be alive. The band played happy music. This music made everyone want to dance. It was an early form of jazz. Music has always been important in Negro life. The black,who were brought to American from West Africa,had a rich musical tradition. In the fields,they made up work songs.

PROBLEM: Article: Any mistake made in the printing of a stamp raises its value to stamp collectors. A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value. The mistake was made more than a hundred years ago in the British colony of Mauritius, a small island in the Indian Ocean. In 1847 an order for stamps was sent to a London printer-Mauritius was to become the fourth country in the world to issue stamps. Before the order was filled and delivered, a ball was planned at Mauritius' Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the design for the stamps. He accidentally inscribed the words "Post Office" instead of "Post Paid" on the several hundred stamps that he printed. Today there are only twenty-six of these misprinted stamps left fourteen One Penny Orange-Reds and twelve Two Penny Blues. Because of the Two Penny Blue's rareness and age, collectors have paid as much as $16 800 for it.

PROBLEM: Article: Due to the increasing number of violence acts produced in schools all over the world, more and more parents prefer to have their children educated at home rather than at school. This way they can ensure their safety and well-being, although teachers and school representatives are trying to improve the situation in schools by increasing the number of the persons in charge of the safety of the students. The main reason for violence acts are the films and cartoons that fill the children's time. They want to do everything they watch on TV and never think of the consequences, and they may hurt a classmate or a teacher. On the other hand, parents are not fully satisfied with the children's results obtained in classes and they consider private classes would have better results. When a teacher has to watch 30 students in class he can't probably see what each of them is doing, how he is writing, or if he understands the explanations. At home the teacher can explain in details everything the child doesn't understand as many times as he considers proper. And many times the child grows fond of the teacher at home, who becomes his best friend, and who helps him whenever he needs someone to talk to. However, the best solution would be a mixture between the education received at school and that at home, because school makes children communicate and socialize. Keeping a child at home for fear there might happen something bad to him only makes the child's character weak and prevents him from knowing what real life is. Staying in _ only does harm to the child. All in all, schools have been created to help children, not to harm them, so it's best to keep children in these special places, where they learn, laugh, have fun and make new friends
