一、高考考情速览（真题数据支撑） 1.核心考查题型：语法填空（100%），考法固定——给词根提示词变词性（占96%），其它方式考查仅占4%；语篇阅读、书面表达无独立考点，仅为基础运用。 2.高频考查类型（按考频排序）：动词→名词（36%）＞形容词→副词（24%）＞名词→形容词（20%）＞动词→形容词（12%）＞形容词→反义词（8%）。 3.考查核心特点：规则词缀变形占95%，仅5%为高频不规则变形；词性由句子成分唯一决定，无纯词形考查；98%为单一词性转换，复合变形占比低。 4.2026考向预测：核心考法不变，三大主流类型占比85%以上；复合变形（动词→形容词→副词、名词→形容词→反义词）占比升至12%；不规则变形结合句法考查；词性转换与冠词、介词、系动词绑定更紧密。 二、考场秒杀解题两步法（真题验证，10秒出答案）
