     You can improve your child's hearing memory considerably(在很大程度上). Once his

hearing memory has been greatly improved, he'll be able to use and remember what he listens

to in class. The success of these suggestions depends upon your ability to use your child's

natural desire to get involved in games he finds simple and fun.

     A good way to begin is to read aloud a sentence from a book suitable for your child's

reading age. Then ask your youngster to repeat the sentence back to you correctly. Next,

reread the sentence, leaving out a particular word. See if your child can identify the word

you left out. At the beginning use only simple sentences. Gradually, increase the length of the

sentences. Make sure you don't rush things along too quickly, or your child may become

discouraged and tired of the game.

in the supermarket. First , ask him to remember only a few things. Then, as he shows increased

shows increased ability to remember things. He'll become proud of his 'good' memory and

will happily play the game.
