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。
