听力原文： Education is required and flee for every child in the United States. Most children start by the age of six. They attend eight years of elementary school and four years of high school (or secondary 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 according to the laws of the individual states, The Federal Government contributes funds to the states for additional school services.
After graduation from the 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 the college education is great 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. Only 2 % of the population of the country cannot read and write.
