普通专升本英语词形变化试题难不难？掌握技巧就不难

词形变化( WordForm )应考方法

1.灵活运用形容词词形变化规律性。留意：动词形式既包含谓语动词的多种方式，如语态、语态及语调(直陈、虚似)等，虚拟语气为关键，两年来的考试题上都有这些方面內容；也包含非谓语动词的多种方式。因此 做形容词的词形变化时，最先要弄清楚它在句中是谓语动词或是非谓语动词，随后再作相对的转变。

2.用心学精并了解课文内容。题中所选择的词句是依据教材内容中产生的语句撰写的，在其中大部分来源于课文内容，因此 了解教材内容十分关键。

3.用心刻苦钻研有关的英语语法解读。关键指谓语动词、非谓语动词、修饰词、介词较为级别、情态动词、虚拟语气修饰词比较级、级，等一部分。
