1、词性转化当空格处所需词类与括号中所给词的词类不同时，就需要词类转化。我们可 据以下3条规则顺利解题：(1) 作主语或宾语用名词形式；(2) 作定语、表语或补足语用形容词形式；修饰动词、形容词或另一副词，作状语，用副词形式。具体解题技巧如下： 第一步：分析结构，确定要填的词在句中充当哪种句子成分。在名词前作定语、 在系动词后作表语、作主语和宾语的补足语，一般要用形容词；修饰动词、形容 词或副词，或修饰整个句子，作状语，用副词；作主语或宾语用名词，或者在冠 词、形容词性物主代词或名词所有格后，用名词。第二步：根据构词法将括号中的词变成所需要的词类。注意：1. 有时不但要注意词性转换，而且还要考虑用
2、表示相反意义的前缀或后缀，其 逻辑意义才通顺；2. 当所给词的词性与空格处所需词的词性相同时，无需改变词性，就可能是 加只改变词义但不改变词性的前缀了。常考考点形容词f副词widefwidely形容词f形容词比较级/最高级widefwider/widest形容词f名词widefwidth形容词f动词widef widen动词f名词instruct f instruction (s)特殊变性happy fhappily, simple fsimply, true ftruly, arrange farrangement， judge fjudgment1.【2019全国 II 卷】Her yea
