词形变换是各省市中的一个保留题型，它所涉及到的形式主要包括：名词的数与格；代词及其格(主格、宾格、所有格)；数词的形式(基数词和序数词)；动词(单数第三人称、过去式、过去分词和现在分词) 及非谓语动词(动词不定式、动名词和分词)；形容词，副词及其比较等级；反义词和同音异义词等。词形变换题一般有三种出题形式：一种是按括号内的要求转换词形；一种是根据句意，用括号内所给词的适当形式填空；还有一种是括号内给出汉语，要求根据句子意思及所给汉语提示，写出空缺处各单词的正确形式。第一种题型，即按括号内的要求变换词形比较简单，要做好它靠平时多积累，强化即可。第二、三种题型较复杂，它涉及动词的时态、语态及各类词之间的相互转化等。
