Learning English just like learning any other foreigh language,is hard work so my first advice is to spend time practicing using English every day.Besides,we should listen to English radio programmes,read English stories and newspapers,watch English films and TV programmes,review what is learnt regularly,keep a diary in English and attend English debbates and speech contests.What's more,be patient and confident.Don't be shy and don't be afraid of making mistakes.We must understand that mistakes are unavoidable.A saying goes" Failure will blossom into success." So be patient with your mistakes and try to awoid them other time.I believe" practice makes perfect".So why not try to speak English as often as you can.
