英语构词法——派生法
有些英语单词是由词缀和词根构成的。在词根前面或后面加上一个词缀构成新词，这种构词法叫作派生法，是英语构词法中最活跃的一种。词缀分为前缀和后缀。派生法也是我们可以发挥能动性从而扩大词汇量的一种方法。大多数情况下，前缀往往改变词根的词义，而后缀更多的是改变词根的词性。

un 不 unhappy, unable, unpopular, unhealthy
mis 错误地 mistake, mislead, misunderstand

en 使……处于某种状态 enable, enrich, encourage
re 再；重复 reuse, retell, rewrite, recycle, rebuild
