1、第十讲构词法考纲解读定方向正确运用构词法知识，是词汇学习的重要途径，同时也是扩大词汇量的一个重要方法。英语中构词法主要分为派生法、转化法和合成法。牢固掌握并熟练运用构词法知识，不仅有助于提高考生对阅读中生词进行辨识的能力，使其更加灵活地应对语法填空和短文改错对于词性转化的考查。重点强化一、派生法在一个词的词根之前或之后加上某个词缀来生成一个新词的构词法，即称作派生法词缀。加在词根之前的词缀叫做前缀，加在词根之后的叫做后缀。1形容词变名词的后缀后缀例词agecyshortshortage不足；短缺efficientefficiency 效率；功效fluentfluency 流利；流畅accura
