例句：The caliber of teaching at this high school is very high.
2. 体会这个词 （进阶篇）
“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”。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。
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.
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.
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.
《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）
Regardless 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%。
3. 从认识到会用（作业）
1）翻译下面的句子：
很多落后地区的年轻人依然渴望优质的教育。
（参考翻译: Many young people in under-developed areas still have a huge thirst for a high caliber education. 或者 A high caliber education remains desirable for many youngsters in backward regions.）
2）结合自己的生活、学习、工作、兴趣等，想象在什么语境下会用到这个表达。先简要描述这个场景，再造句。
场景： 这家医院有最好的医生
造句：The hospital boasts the doctor of the highest caliber.
