Settle into a quiet spot, such as a library, where you won't be distracted by phone calls, visitors, television or that pint of ice cream in the freezer.
Look briefly over the entire book or article. This will help you get a feel for the overall structure of the piece.
Read only what you need to read to meet the task your teacher or professor has set for you. Don't waste time on insignificant details.
Pay particular attention to introductory and concluding paragraphs. These often contain summaries of important points.
Take reading notes and/or highlight important sections. (See related eHows.)
