核心语法：形容词和副词的最高级

这是本单元的重中之重。

构成规则

构成方式	原级	最高级	规则说明	例词
一般情况	tall	tallest	直接在词尾加 -est	long -> longest nice -> nicest
以不发音的 e 结尾	nice	nicest	直接加 -st	fine -> finest large -> largest
“辅音+y”结尾	easy	easiest	变 y 为 i，再加 -est	happy -> happiest funny -> funniest
重读闭音节，且末尾只有一个辅音字母	big	biggest	双写末尾辅音字母，再加 -est	hot -> hottest thin -> thinnest red -> reddest
多音节和部分双音节词	beautiful	the most beautiful	在词前加 most	expensive -> the most expensive important -> the most important
不规则变化	good	the best	�要特殊记忆	well -> the best bad -> the worst far -> the farthest (距离) / the further (程度)

用法

• 句型结构：

  
  （图片来源网络，侵删）
  • A + be 动词 + the + 形容词最高级 + (名词) + in/of + 范围.
  • A + 行为动词 (实义动词) + (the) + 副词最高级 + (in/of + 范围).

• 关键点：

  1. 必须有范围: 最高级比较必须在三者或三者以上，并且要明确比较的范围（用 in 或 of 引导）。
     • in + 地点/场所范围 (在...范围内)
       • Tom is the tallest boy in our class. (汤姆是我们班最高的男孩。)
     • of + 人/物范围 (在...之中)
       • This is the most expensive of all the shirts. (这是所有衬衫中最贵的。)
  2. the 必须用: 形容词最高级前通常要加定冠词 the。
  3. 比较对象要一致: 比较的必须是同类事物。
     • 正确: The apple is the biggest of the three. (这三个苹果中，这个是最大的。)
     • 错误: The apple is the biggest of the three boys. (苹果不能和男孩比大小。)
