小知识
To justify is to make excuses for one's actions, like the dieter who has to justify the few tiny pieces of chocolate she's sneaked in between salads.
Anyone who has ever made excuses for his or her actions knows the meaning of justify, like the bank robber who justifies his latest heist by claiming he needs the bank's money to support his charitable foundation. He might think he's got a good reason for holding up the bank, but he's going to have a hard time convincing the bank's owner of his reason, or justification. To justify a line of text is to space it so that it lines up with the margin.
实用短语
单词用法
justify by,justify in这两个短语意思和单词用法都相近，其区别是：1.在意思上，in的宾语往往表示有理由所做的事的具体内容；而by的宾语往往表示证明做某事有理的方式。2.在单词用法上，by后常接动名词；而in后常接名词。justify,warrant这两个词都可以表示“为…提供情况或根据”。其区别是：1.justify着重强调提供道德或理智方面的证据；warrant指提供权威、先例、经验或合乎逻辑的理由、根据来证明某事是有道理的。例如：No consideration on earth justifies a parent in telling lies to his child.无论出于哪种考虑，家长都没有理由对孩子撒谎。The history and appearance clearly warrant such assumption.历史与现实清楚地证明了这一假设。2.justify常用于对非正义行为表示反对；warrant常用于对某人或某事的支持。例如：Can you justify your rude behaviour to me?你能向我说明你的粗野行为是有道理的吗?I?ll warrant him an honest and reliable fellow.我可以保证他是一个诚实可靠的人。justify,account for,explain,rationalise这组词都有“讲明原因，进行合理的说明”的意思。其区别在于：1.account for多表示对金钱、货物的使用或开销等作出说明；explain主要用于解释那些性质神秘、缺乏充足理由或者前后矛盾而令人费解的事物；rationalise指为自己不合情理的行为或观点找出原因；justify则用于证明某人或某种言行是正确的。2.explain在本族词中使用最普遍。justify的语气最强，给出的理由最有说服力。例如：He was unable to account for the deficit in the firm?s bank balance.他无法解释这家公司在银行结账为什么会超支。These sciences have noy succeeded in explaining the phenomena of life.科学并未能成功地解释生命现象。I can?t rationalize my absurd fear of insects.我怕昆虫，毫无道理，不能合理地解释。I do not see at all how he can justify himself for such conduct.我完全想不出他如何为自己的行为辩解。justify,assert,defend,maintain,vindicate这组词都有“坚信”的意思。其区别在于：maintain指坚持维护某种主张或某一事物，暗示在反对意见面前或在争论当中怀有坚定不移的信念；assert强调把自己的信念强加于人或者企图硬要别人信服或认可；defend专指捍卫某种行动、意见、决定等以免受到非难、惩罚或责备；vindicate特指在受到非难、责备、轻视等时为自己辩明或剖白；justify指用无可辨别的理由“证明…有道理或有根据”。例如：He maintains his innocence.他坚持说他无辜。He asserted that he had seen it happen.他断言他曾看见那事发生。H
