听力原文： I want to talk a little bit today about the revolution in American education. We must leave no child behind. We are not satisfied with a society that graduates citizens who cannot read, write or do basic math. Nor are we satisfied to turn out young men and women unprepared to enter fine institutions of higher learning such as this—unprepared to compete in the global economy—unprepared, really, for life itself. Our revolution in education will take an evolution in awareness and thought. We can do it! (88)
