比较级的用法:
(一)当两个人或事物（A和B）进行比较时，我们需要用到形容词（副词）的原级或者比级
1． 表达“A和B一样”，用as…as的结构。
公式: A+be动词+as+形容词原级+as…+B
A+实义动词+as+副词原级+as…+B
Eg : I am as tall as you.我和你一样高
He runs as fast as I. 他跑得和我一样快。
2．表达“A不如B”用not as…as的结构。
公式: A+be动词+not+as+形容词原级+as…+B
A+助动词+not+动词+as+形容词原级+as…+B
Eg I am not as tall as you.我没有你高。
He doesn’t run as fast as I. 他没有我跑得快。
2． 表达“A大于B”用“比较级+than”的结构。
公式: A+be动词+形容词比较级+than+B…
Eg I am taller than you.我比你高。
He runs faster than I. 他跑得比我快。
(二)关于形容词比较级的更多用法
1．比较级前面可以加上表示“优劣程度”的词或短语，意思是
“更…”，“…得…”。
常见词有much许多，大量 a little，一点儿，少量,
even甚至, a lot许多, a great deal大量等。
Eg He is much taller than I.他比我要高得多。
I jump a little higher than he.我跳得比他高一点点。
2.比较级前面可以加上表示具体数量差别的结构,
表示具体“大多少”，“小多少”，“长多少”，“短多少”等。

四、当三个或三个以上的人或事物进行比较时，我们需要用到形容词的最高级
1．表达“…是…中最…的”,
用“the+形容词的最高级+in/of /among +范围”的结构。
Eg.He is the tallest (student) in our class. 他是我们班最好的学生之一。

这是花园里最漂亮的花之一。
注意：(一) 形容词的最高级前面有定冠词the，
但在形容词最高级前有物主代词（my /mine等）时，不能要定冠词the.
五、运用形容词比较级应当注意的问题：
(一)、只有同类的事物才能比较
e.g Her bag is bigger than mine. 她的包比我的更大。
不能说 Her bag is bigger than I. 她的包比我大。
The weather of Kunming is much better than that of Shenyang.
昆明的天气比沈阳的要好得多。
不能说The weather of Kunming is much better than Shenyang.
昆明的天气比沈阳好得多。
（二）、如果比较对象相同，可用that/those代替第二个比较对象，
如：
The texts in Book One are much better than those in Book Two.
书中的课文比第二册的好得多。
