用法：英語中三者或三者以上相比較，表示“最……” 這樣的最高程度概念時，要用 “the+最高級” 的結構表示。這種句式一般帶有表示比較的介詞短語，比如: in our class, of the three 等。
例如: Wang Lin is the tallest in our class.
This theater is the cheapest of the three.
注意使用最高級時應注意以下幾點：
形容詞、副詞最高級
①表示 “最……之一”的句式，要用 one of the +形容詞最高級+復數名詞。例如：
例如: Jingjiang Hotel is one of the biggest hotels in our city.
Lisa is one of my best friends.
②當最高級前面有物主代詞或名詞所有格時, 不加定冠詞 the。
例如：Tom is Lucy’s best friend.
Tuesday is her busiest day.
形容詞、副詞最高級
③最高級前可加序數詞。例如：
The Yellow River is the second longest river in China.
④形容最高級修飾作表語或介詞賓語的名詞，代詞時，被修飾的詞往往省略.例如：
He is the laziest (student) in our class.
形容詞、副詞最高級
in
+ 范圍
This is the biggest city in China.
He was the youngest player in the team.
表示 “在…… 范圍內”，后接大范圍（如地點、組織、時間階段等）。
of + 具體成員/同類事物
She is the most talented of all the students.
This apple is the sweetest of the five.
形容詞和副詞的最高級的范圍
表示 “在…… 中”，后接具體的人或事物（復數名詞 / 集合名詞），強調從同類中選出 “最……” 的個體。
among + 同類群體
He is the richest man among the billionaires.
Which is the smallest among these birds
強調 “在…… 群體中”，后接復數名詞或代詞，可與 of 互換，但 among 更側重 “在多者之間” 的分布感。
out of
+ 明確范圍
She scored the highest marks out of all candidates.
This song is my favorite out of his new album.
表示 “從…… 中”，后接明確的復數名詞或代詞，常用于強調 “從某一特定范圍中選出”。

This is the longest river I've ever seen.（g 結尾）
That's the biggest apple on the tree.（g 結尾）
He is the smartest boy in the grade.（t 結尾）
