听力原文: There have always been disabled children. Long before, people with disabilities were often placed in hospitals, or other places that gave little education. A French educator was one of the earliest teachers who believed that people could tree special methods to teach disabled children. In 1801 he found a young boy walking wild in the woods of France. Between 1801 and 1805 he used some techniques to teach the boy how to communicate with others and how to complete daily living skills, such as dressing himself.
During the 18th and 19th centuries in the United States, educators opened a variety of special schools for disabled students. In 1816 an American minister established the first public school for deaf students in the United States. The first school for blind students in the United States was founded in 1829 in Boston. Special education classes began at the beginning of the 20th century.
Special education in the United States has been most influenced by parents and laws. Although all children should go to school by laws, many U. S. schools refused children with disabilities even in the 1960s. Since then, attitudes have changed, and now laws require schools to give children with disabilities necessary education.
