请教一段英语翻译

Brian 's experience shows us that it really play a great important role in  mastering some knowledge about first aid . Brain was studying in his room, suddenly he heard a scream of his mother.So he rushed into the kitchen and found that her mother scalded herself in cooking.Her wrist blistered and there was some water on the surface.Then Brain remembered something that he have learnt at school.So at first, he took down her mom'clothes near the wound .Besides, he put some clean cloth in cold water and put it on the burned area after twisting water.It repeated over and over again until she did not feel too pain.At last,he found out a dry and clean bandage to cover the burned area with a bandage bandage fixing.Afert it,he followed his mother to go to see a doctor.The doctor said that if  Brain hadn't done those emergency handling ,his mom's hand will   scald even worse.可能会因为马虎有拼写错误，不当之处，望指正！呵呵，希望对你有所帮助。
