Society is changing, and students are changing with it. The overwhelming impact of television alone has made students more sophisticated, more aware, more mature. But it has also threatened to leave them less literate, less able to express themselves effectively in writing, less familiar with basic elements of language structure. To fulfill its obligations, a textbook must meet changing needs while retaining what is of central importance to the preservation of cherished values. This extensive revision of Modern English in Action addresses itself squarely to the problems implicit in the preceding statements. It has introduced much new material, chosen content to appeal to the increasing sophistication of students, and broadened its appeal to accommodate the diversity that is both a strength and a challenge of modern American life. It has intensified its attack on the problems of illiteracy. It has restructured sections in grammar and usage, providing far more drill material than previously. At the same time it has reinforced the writing program, expanded the reading program, and provided additional emphasis upon listening as a key skill.
