　　Prof.John Groeger，University of Surrey’s Sleep Research Centre，said，“People have been trying for years to find out what the purpose of sleep is，as we know that only certain parts of it have a restorative (促使康复的) value.”

　　“We form and store huge numbers of experiences in the head every day，and sleep seems to be the way the brain deals with them all.”
