构词法就是一个单词通过转化、派生、合成等构成另一个新词的方法。高考命题虽以考纲所列词汇为依据，但考纲词汇通过构词法变成的新词是不算超纲词的，这类词在每年每份试卷中约有50个，如果不掌握好构词法，这几十个词很可能会成为我们阅读的障碍。不仅如此，需要构词法解答的题，在语法填空中会有1-3题，短文改错中会有1-2题。因此，掌握构词法，非常必要。
需要构词法知识解答的语法填空和短文改错题主要考查以下三点：
1. 作主语、动词宾语或介词宾语，用_____
2. 作定语、表语和补语，一般用_______
3. 修饰动词、形容词、介词短语、从句或整个句子，要用_____
三种构词法:
1.派生(Derivation):
2.合成(Compounding):
3.转化(Conversion)
