Step 3 Grammar
我们已经学习过形容词和副词的比较级和最高级的构成及基本用法。下面我们进一步学习
与其相关的其他知识点。
◆形容词和副词比较级的修饰语
1. 比较级前可加much, a lot, a bit, a little, any, no, some, even, still等词修饰。如：
You must work much faster.
You look a lot happier than you did yesterday.He was too tired to walk any further.
This book is even more useful than that one.
2. 比较级前还可加其他表示数量的词。如：
My sister is ten years younger than me.
We reached here two days earlier than the others.
◆形容词和副词最高级的其他用法
1. 形容词最高级可被second, third等序数词修饰。如：
The building is the second tallest in this city.
2. 形容词最高级常用于句型“one of +the+形容词最高级 + 可数名词的复数形式”，意为
“最……之一”。如：
Liu Li is one of the most popular girls in our class.
3. 形容词和副词的比较级和最高级可以互相转换。如：
Jane is taller than the other girls / any other girl in the club. = Jane is the tallest girl in the club.
This car runs faster than the other ones / any other one in the garage. = This car runs the fastest of
all the cars in the garage.
