四、知识要点
知识要点1：形容词最高级的用法
【概念解释】形容词最高级用于三者或三者以上的比较，表示"最……"，前面通常加定冠词 the。
【教材依据】教材 pp.41 Grammar Fcus 部分，通过 Victria Falls、Munt Kilimanjar 等自然景观的描述呈现最高级用法。
【应用方法】判断比较范围：两者用比较级，三者及以上用最高级。注意 in + 范围（地点/群体）和 f + 范围（同类事物）的搭配。
知识要点2：大数的英文读写规则
【概念解释】英语大数从右向左每三位加一个逗号分隔，分别对应 thusand, millin, billin。
【教材依据】教材 pp.41 练习中涉及 5,895、25,768、337,000 等地理数据的英文拼写。
【应用方法】先标逗号分节，再从高位到低位逐节读出。注意 hundred/thusand/millin 在确切数字后不加 -s，百位与十位间加 and。
知识要点3：比较级与最高级的辨析
【概念解释】比较级用于两者比较（A is taller than B），最高级用于三者及以上比较（A is the tallest in the class）。
【教材依据】教材 Grammar Fcus 通过圈出比较形容词、划线比较副词的练习帮助学生区分。
【应用方法】看比较对象数量：两者→比较级+than；三者及以上→the+最高级+in/f。注意 sme f 后用最高级。
