Children are amazing! They pick up language so naturally and easily．Have you ever wondered why? It's because of the way they learn．

Children learn by simply doing what comes naturally--they listen，copy，and communicate．Let's take a closer look at how children learn language．Perhaps we can discover a better，more “natural” way to learn English．

Listen as often as possible

When people talk to children，they often use simple words that children can understand．That's really important to the children's language development．In order to learn，children must be able to understand what they hear．If they don't understand it，it's just meaningless noise．

Listen to radio or TV programs that use English at your level．If you can't understand every word or sentence，don't give up．Just pay attention to what you can understand，And listen as often as you can．

Be a Copycat

Children like to copy their parents，their friends and even the TV．（the，teaches，this，how，pronounce，them，language，to）．As you listen to English，repeat what you hear as much as you can．

Use English to communicate

Children don't practice grammar rules．They use language to talk about things that interest them．This helps them learn to express themselves．They don't worry about their small vocabulary or poor grammar．They find ways to say what they want and they do it successfully．

So look for chances to talk with people in English．If you can't find a foreigner to talk to，talk with other English students instead．Start an English discussion group and chat about music，movies and so on．Don't worry about making mistakes．You can learn English better by correcting mistakes．
