1. 认识这个词（基础篇）
词：perfect
英英释义：to make something as good as you are able to
例句：Jiro Ono, arguably the best living Japanese sushi chef, has devoted his entire life to perfecting the art of sushi.
2. 体会这个词 （进阶篇）
“perfect”既可以作形容词也可以作动词，作动词的意思是“使......完美、提高”，可以和 improve 同义替换。略有不同的是，perfect 更能体现一个人的决心和持久力，有精益求精、匠人之心的意思。从 perfect 的动词意思也可以看得出，它后面经常会接 skill, technique 等词。
注意：perfect 作形容词的读音是/ˈpəːfɪkt/；作动词时，它的读音和重音都会发生变化，读成/pəˈfɛkt/。
下面来看几个例句。
日本寿司之神小野次郎穷尽一生精进寿司手艺，用英语可以这么表达：

It was in college that Barack Obama perfected the art of oratory/public speaking.
