詞語用法

v. (動詞)
  1. ascertain的基本意思是“發現前所未知的事物”。通常指意識到了自己的無知之后通過有意識的努力來弄清真相或找出事實。

詞義辨析

v. (動詞)
ascertain, determine, discover, learn, unearth
  • 這組詞都可表示“發現以前自己不知道的東西”。其區別是:
  • discover指經過調查、探索去發現已經存在或可能存在、事實上的東西,這種發現也可能出于偶然; ascertain很少指偶然的發現,側重先前的無知與無把握,以及認真地去發現真理或真相; determine比ascertain更強調尋找事實或真理,以解決爭端或爭執,主要用于科學和法律方面; unearth指將隱藏的、被遺忘的、失去的或極其難以追尋的東西公之于眾或暴露于世,常常強調發現以前所做的認真長期的調查; learn指獲得知識,發現者一般沒有或很少花多大力氣。例如:
  • The surgeon general has determined that cigarette smoking is dangerous to our health.衛生局長已確定吸煙危害健康。
  • The question is to ascertain what the people really want.問題在于一定要弄清人們究竟需要什么。
  • We discovered the powder consisting of harmful ingredients.我們發現這種粉末含有害成分。
  • Projecting ourselves into the future world, we should learn as much as we can now.設想一下處身于未來的世界當中,我們現在就應該盡可能多學一點東西。
  • They have unearthed the secret.他們已經發現了這個秘密。
  • discover,find,detect,ascertain
  • 這些動詞均有“發現”之意。
  • discover指發現本來已經存在,后被人認識的事物、真理或情況。
  • find普通用詞,可指偶然發現,也可指經過尋找后得到或重新獲得已失去的東西。強調動作的結果。
  • detect正式用詞,強調經過周密觀察或研究而有所獲得和發現,尤指發現有意隱藏之物。
  • ascertain較正式用詞,指有意搜尋與發現。
