Unit 5 How do inventions change our lives? 核心语法点：多音节副词的比较级与最高级 一、语法精讲 1. 定义：多音节副词（通常以**-ly结尾，除early外）的比较级和最高级不能加-er/-est，要用more+副词原级**（比较级）和most+副词原级（最高级）。 2. 教材例句： · Peter runs slowly.（原级） · Eddie runs more slowly than Peter.（比较级，教材原句） · Mark runs the most slowly of the three.（最高级，教材原句） 3. 常见多音节副词：slowly, quickly, carefully, easily, happily 4. 核心结构： · 比较级：主语 + 实义动词 + more + 副词原级 + than + 比较对象 · 最高级：主语 + 实义动词 + (the) most + 副词原级 + 范围 5. 易错警示 · ❌ 错误：He runs slowlier than me. · ✅ 正确：He runs more slowly than me.（slowly是多音节副词，不能变y为i加er） · 副词最高级前面的the可以省略：He runs (the) most slowly in our class. 二、语法点即时练习（每题附解析） （一）单项选择题（5道） 1.
