intermediate，medium，mid，middle作为“中间的”意思，怎么进行区别呢？ intermediate和medium比较像，mid和middle比较像。所以分两组来说。 按词性来看，就仅看它们的形容词（mid就是个词缀，之后再细说） 前一组指的是“高中低”“大中小”的“中”，表示程度，即somewhere between two extremes。 例如， intermediate course 中等课程， small and medium-sized enterprises 中小企业。 后一组呢
Middle School 和 High School 都是中学吗？那初中和高中怎么区分？ - 知乎 middle school: 1) a school in Britain for children between the ages of 8 and 12; 2) a school in the US for children between the ages of 11 and 14 high school: 1) a school in the US and Canada for children of 14 or 15 to 18 years old; 2) used in the names of some schools in British form children from 11 to 18 years old
