※ 引述《ar880878 (@hotmail.com = =a)》之铭言： : extraneous : ◎ not directly connected with the particular situation you are in or the : subject you are dealing with (From Oxford Advanced Leaner's Dictionary). : ◎ 1 : existing on or coming from the outside (From W-M.com) : 所以 concealed (藏起来的 >> 关在里面) 是下列五组选项最好的选项.. : : a) indeterminate irresolute : : b) modified 修正过的、调整过的 : : c) accrurate 准确.. : : d) concealed : : e) essential 很重要的、本质上的、关键的、 : : [2] 我喜欢用 " The Free Dictionary " http://www.thefreedictionary.com 下面有 Thesarus 的方块可以自动看一堆同义词，虽然他的用词大多都很口语 ^^;; http://www.thefreedictionary.com/extraneous adj. 1. Not constituting a vital element or part. 2. Inessential or unrelated to the topic or matter at hand; irrelevant. See Synonyms at irrelevant. 3. Coming from the outside: extraneous interference. : virulent : 1 (of a disease or poison) extremely dangerous or harmful and quick to have : an effect: a virulent form of influenza : 2 (formal) showing strong negative and bitter feelings: virulent criticism : virulent nationalism : : a) intermittent : : b) courteous : : c) defeated : : d) confident : : e) salubrious http://www.thefreedictionary.com/virulent adj. 1. a. Extremely infectious, malignant, or poisonous. Used of a disease or toxin. b. Capable of causing disease by breaking down protective mechanisms of the host. Used of a pathogen. 2. Bitterly hostile or antagonistic; hateful: virulent criticism. See Synonyms at poisonous. 3. Intensely irritating, obnoxious, or harsh. http://www.thefreedictionary.com/salubrious salubrious adj. Conducive or favorable to health or well-being. 所以是用在形容一个东西具有可以导致健康健全的某种属性， 而非形容一个人是健康的；这与virulent是指一个东西具有有 毒性的属性好像还满合的 ^^;; （题外话下面的同义字 'good for you' 实在是最简洁有力的解释了 :p ） 实在是超难选的呀～～ -- Working men of all countries, unite!
