词语用法

词义讲解

v.(动词)

ascertain的基本意思是“发现前所未知的事物”。通常指意识到了自己的无知之后通过有意识的努力来弄清真相或找出事实。

ascertain是及物动词,接truth, fact等名词或名词从句作宾语,可用于被动结构。

v.(动词)

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*长已确定吸烟危害健康。

The question is to ascertain what the people really want.问题在于一定要弄清人们究竟需要什么。
