To become an efficient reader,you should not only improve your reading'comprehension,but also increase your reading speed.you should learn to read faster without lowering your reading comprehesion.
In order to read faster,you should read silently instead of aloud.Of course,you ought to practise reading aloud if you want to improve your pronunciation and intonation;but not when you rend for information.This is because one can read much faster siently than he reads aloud.
Another way to read faster is to read in sense groups.Slow readers read one word for a time.They are perceiving single word as single words.If it is a long sentence contain smaller meaningful units,called sense groups.
