Do you have any of these bad habits ? Check yourself by answering  “yes”or“no” to these questions.

a)      Do you move your lips when reading silently ?

b)     Do you point to words with your fingers as you read ?

c)      Do you move your head from side to side as you read ?

d)     Do you read one word at a time ?

If your answer “yes”  to any of these questions , start at once to break the habits. If you move your lips, hold your fingers over them, or hold a piece of paper between your lips while you are reading. Then when your lips move, you will know it and stop them. If you point to words, hold the two sides of your book, one side with your left hand, the other side with your right hand. Then you won’t have a free finger to use in pointing while reading. If you move your head, place your chin in one hand, and hold your head still.

If you read no more than one word at a time, you need to work in learning to take in more words at each glance as your eyes travel across the lines of words. Even if you read fairly fast now, you can learn to even faster. As you probably have been told, the secret of fast reading is to take in whole groups of words at each glance. Read in several groups and force your eyes along the lines of words as fast as you can make them go. Anyone who practices doing these two things will be able to read faster.
