听力原文： THE BLIND ATTENDING UNIVERSITY

The World Health Organization says almost forty million people around the world are blind. /There are about one million blind people in the United States./The largest and most influential organization of blind people in this country is the National Federation of the Blind./Officials say the nation does not have any colleges or universities/that serve only blind students. /They say the reason for this is that blind people must learn to live among people who can see./

American colleges and universities do accept blind and visually impaired students. / And they provide services to help these students succeed./For example, colleges find people who write down what the professors say in class./And they provide technology that can help blind students with their work./However, experts say colleges can best help blind students/ by making it clear that the students should learn to help themselves./
