It’s the largest / biggest animal in the world.
…
1d
1. What’s the largest animal in the world 世界上最大的动物是什么？
largest是large的最高级形式。最高级前面一般会有定冠词the进行修饰。
形容词和副词的最高级一般分为规则变化和不规则变化。
规则变化如下：
构成方法 比较级
单音节词和部分双音节词 一般情况下，最高级词尾加-est tallest；shortest；fastest
以字母e结尾的词，最高级词尾加-st largest；latest
重读闭音节词尾只有一个辅音字母时，先双写该辅音字母，然后最高级词尾加-est biggest；fattest；thinnest
以“辅音字母+ y”结尾的双音节词，先把y改为i，然后最高级词尾加-est easiest；heaviest；earliest
多音节词和部分双音节词 词前加most构成最高级 most beautiful；most popular
Language points
不规则变化如下：
原级 最高级
good / well best
bad / badly worst
many / much most
little least
far farthest
furthest
例如：
What’s the largest animal in the world
Which animal runs the fastest
What is the oldest plant in the world
Which kind of tree is the tallest in the world
2. Well, I think moss is one of the oldest plants. 嗯，我认为苔藓是最古老的植物之一。
one of + 限定词 + 复数名词 / 代词
限定词包括冠词（the）、形容词性物主代词（my, their）、指示代词（these, those）等。表示 “…… 中的一个”，强调在整体中选取一个个体。
例如：
She is one of my friends. 她是我的一个朋友。
This is one of the best movies I’ve ever seen.
这是我看过的最好的电影之一。
【主谓一致】
one of 结构作主语时，谓语动词用单数（因为核心词是 “one”，表示 “一个”）。
例如：
One of the students is from Canada. 这些学生中有一个来自加拿大。
One of these books has a missing page. 这些书中有一本缺页了。
【最高级搭配】
“one of” 常与 形容词最高级 连用，构成 one of the + 最高级 + 复数名词，
表示 “最…… 的…… 之一”。
The Great Wall is one of the greatest wonders in the world.
长城是世界上最伟大的奇迹之一。

Pronunciation

Pay attention to the pronunciation!
Listen and repeat. Notice the difference in stress and meaning of the same sentence.

在英语句子中，实词（如名词、动词、形容词、副词等）承载重要信息，一般需要重读；而充当语法功能的词（如冠词、连词、介词、助动词等）一般弱读。但这条读音规律并非一成不变，句子中的重音可以随着说话者要表达的意思的变化而变化。例如：
Please pass me the book. （强调把“书”递给我，而不是把别的东西给我）
Please pass the book to me. （强调把书递给“我”，而不是给其他人）
A: I think she will win.
B: She won’t. （预测她“不会”赢）
A: She will. （坚信她一定“会”赢）
一般情况下，me、will等功能词在句中弱读，但在上述情境中这两个词需要重读。
