This document defines reading as a complex mental process where the reader uses strategies to understand the meaning intended by the author based on text and prior knowledge. It identifies reading as a rapid, comprehending, interactive, strategic, flexible, purposeful, evaluative, and learning process that uses linguistic knowledge. There are three main reasons for reading: survival, learning, and pleasure. Effective reading involves a flexible response guided by the reader's purpose. Fluent readers notice features, read for meaning, predict, apply background knowledge, use repetition, and switch between text and knowledge. Implications are that L2 reading instruction should consider varied student goals, tasks, texts and objectives.
