英英释义：not needing to be demonstrated or explained; obvious
例句：It is self-evident that childhood experiences influence our adult behavior.
2. 体会这个词 （进阶篇）
“self-evident”是形容词，意思是“不言而喻”“明摆着的”，是一个口语和写作中都很实用的小词。它的用法也比较简单，程度比 evident（明显的）更强烈，接下来我们通过几个例子掌握它的用法。
美国 1776 年颁布的《独立宣言》中最著名的就是这句话：
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.
（我们认为下述真理是不言而喻的：人人生而平等，造物主赋予他们若干不可让与的权利，其中包括生存权、自由权和追求幸福的权利。）
当我们想表示某个结论显而易见，就可以用 self-evident。比如我们童年的经历会影响我们成年后的行为，这是众所周知、明摆着的事，于是就可以说成：
It is self-evident that childhood experiences affect our adult behavior.
大家都知道学好一门外语的好处，不过许多人还是半途而废：
While the bonus of mastering a foreign tongue is self-evident, legions of language learners quit halfway through the journey.
我们再来看看《经济学人》中用 self-evident 的例子：
1）While the show's cultural impact is becoming self-evident“Hamilton” has also been a smashing commercial success: tickets are sold out through January 2017.
2）This truth, self-evident after the recent crisis, has been ignored by many economists, in part because it was assumed, under the efficient market hypothesis, that asset markets cannot be overvalued.
3）Live longer, work longer: the cure for population ageing is self-evident, if unpalatable.
3. 从认识到会用（作业）
翻译下面的句子：
这样行动的危险是明摆着的。
（参考翻译：The dangers of such action are self-evident.)
