“caliber”是个不可数名词，最常见的意思是“质量”，也常常用来表示“素质”。英英释义：the level of someone’s ability, intelligence etc, or the standard or quality of something, especially when it is high. 我们常常可以用它来替换常见的 quality，是个在口语和写作中都会让人眼前一亮的实用表达。
例句:
① Justin 老师在英文随笔中就多次用到了 caliber。比如在用英文吐槽《纽约客》的订阅体验时他写道：
The subscription experience proves to be unworthy of the brand and caliber for which The New Yorker is known.
② Justin 老师在描写瑞幸咖啡的高品质标签时写道： It boasts three major highlights: premium Arabica coffee beans, recipes devised by award-winning baristas, and fresh brewing, all signs of high caliber.
③ 我们平时说的“高质量”“高素质”就是“high caliber”，口语之中想说“教学质量非常高”就可以说成： The caliber of teaching at this high school is very high.
④《经济学人》中也经常使用 caliber，比如： Our aim is not to predict the winner in Russia, which can be done best by looking at a team's recent results or the calibre of its squad. （要注意 caliber 的英式写法是 calibre。这里的 calibre of its squad 指的是这个足球队的素质）
⑤Regardless of family income, a graduate from one of the Ivy League-calibre institutions, has roughly a two-thirds chance of making it into the top 20%. 我们可以从这句话中学到 caliber 的灵活用法，Ivy League-calibre 指的是“有常春藤级别质量的”。句中的 20% 指的是社会地位最高的 20%。
