mad(informal, especiallyBrE) having a mind that does not work normally指疯的、神经错乱的、有精神病的：◆I thought I'd go mad if I stayed any longer.我觉得再待久一点我就会发疯。NOTEMad is an informal word used to suggest that sb's behaviour is very strange, often because of extreme emotional pressure. It is offensive if used to describe sb suffering from a real mental illness; use mentally ill instead. Mad is not usually used in this meaning in North American English; use crazy instead. * mad 为非正式用语，暗指由于极度的精神压力而行为怪异，用于真正的精神病患者意含冒犯，故用 mentally ill 代之。在美式英语中，通常不用 mad 表示此义，而用 crazy。
