Sit in a comfortable chair at a table or desk with a book or other reading material. Read as many words as you can in a block rather than as single words, increasing the number of words each time you practice. Hold the book a little further away, which may make it easier to increase the number of words you can read as a block.
Tell yourself not to pronounce the words in your mind as you read them, and continue trying to read more blocks of words, as you will not be able to sound these out in your mind as you're reading them.
Relax your facial muscles and your gaze as you read, which will enable you to see the blocks of words more clearly as your eyes learn to drift across a page. Use your peripheral vision as you reach the end of a line of text to take in the last groups of words. Don't let your eyes stay too long on a line before moving to the next one.
Use a pen or pencil as a pointer to run across a line as you read, letting your eyes follow the pointer, which will help you to train yourself not to reread any material. Move your pointer, a card, or a piece of folded paper down the center of a page of text, forcing your brain to keep up the pace.
Avoid multitasking while you read, and clear your mind as much as possible of any internal distractions, such as thoughts about what you will wear to tonight's party. Turn off the TV and the radio, and try to find a spot for reading that will present you with the fewest distractions.
