B: She ʹwon’t. （预测她“不会”赢） A: She ʹwill. （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。 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 【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。 Language points 用所给词的适当形式填空 We _________(agree) on a plan to protect redwood trees yesterday.
