听力原文： Education is compulsory and free for every child in the United States. Most children start school by the age of six. They attend eight years of elementary school and four years of high school. The money for free public schools comes from taxes, and each state is responsible for its own educational system. State legislatures set the educational requirements but leave the management of the schools in the hands of the local communities. Most states require their children to go to school until a certain age. This age varies from 16 to 18 years according to the laws of the individual states for additional schools and school services. After graduation from high school, a student can start his higher education in a two-year college, a four-year college, a university, or a specialized professional school -- either public or private. Most colleges admit students on the basis of their high-school records. The cost of a college education is expensive in private universities, but it is much less in those supported by states and cities. Many students receive scholarships from the schools, the government, or private foundations and organizations. More than 50%of the college students work to help pay their college expenses.
Where does the money for public schools come from？

People have been painting pictures for at least 30,000 years. The earliest pictures were painted by people who hunted animals. They used to paint pictures of the animals they wanted to catch and kill. Pictures of this kind have been found on the walls of caves in France and Spain. No one knows why they were painted there. Perhaps the painters thought that their pictures would help them to catch these animals. Or perhaps human beings have always wanted to tell stories in pictures.
About 5,000 years ago the Egyptians and other people in the Near East began to use pictures as a kind of writing. They drew simple pictures or signs to represent things and ideas, and also to represent the sounds of their language. The signs these people used became a kind of alphabet.
The Egyptians used to record information and to tell stories by putting picture- writing and pictures together. When an important person died, scenes and stories from his life were painted and carved on the walls of the place where he was buried. Some of these pictures are like modern comic strip stories. It has been said that Egypt is the home of the comic strip. But, for the Egyptians, pictures still had magic power. So they did not try to make their way of writing simple. The ordinary people could not understand it.
By the year 1000 BC, people who lived in the area around the Mediterranean Sea had developed a simpler system of writing. The signs they used were very easy to write, and there were fewer of them than in the Egyptian system. This was because each sign, or letter, represented only one sound in their language. The Greeks developed this system and formed the letters of the Greek alphabet. The Romans copied the idea, and the Roman alphabet is now used all over the world.
These days, we can write down a story, or record information, without using pictures. But we still need pictures of all kinds: drawings, photographs, signs and diagrams. We find them everywhere: in books and newspapers, in the street, and on the walls of the places where we live and work. Pictures help us to understand and remember things more easily, and they can make a story much more interesting.
Pictures of animals were painted on the walls of caves in France and Spain because ______ .
