能查到的draw inferences from one instance 太书面又啰嗦，有没有口语化一点的表达？

JU YI FAN SAN

Half a tale is enough for a wise man


这个比较接地气

I will hit you three if you touch me once

take one against three

buy 1 get 3

learn by analogy

谷歌翻译的，个人觉得意思基本到位。

You kill my dog I kill your family

见树叶，知森林，大概是这么个意思

satoru

Draw inferences about other cases from one instance

developing more based on one single idea

i raise up one chestnut，you got three
