ascertain, determine, discover, learn, unearth这组词都可表示“发现以前自己不知道的东西”。其区别是： discover指经过调查、探索去发现已经存在或可能存在、事实上的东西,这种发现也可能出于偶然; ascertain很少指偶然的发现,侧重先前的无知与无把握,以及认真地去发现真理或真相; determine比ascertain更强调寻找事实或真理,以解决争端或争执,主要用于科学和法律方面; unearth指将隐藏的、被遗忘的、失去的或极其难以追寻的东西公之于众或暴露于世,常常强调发现以前所做的认真长期的调查; learn指获得知识,发现者一般没有或很少花多大力气。例如: The surgeon general has determined that cigarette smoking is dangerous to our health.卫生局长已确定吸烟危害健康。
