要点：比较级是用来比较两者或两部分之间的差异。比较两者时使用比较级，并使用“than”连接。
例如：
他比 Jim 高。
这条河流比那条河流长。
这本书比那本书重。
He is taller than Jim。（在使用比较级时不能使用原形。）
（tall-taller；long-longer；heavy-heavier）
要点：最高级是用来比较三者或三者以上的情况，需要注意比较的范围。
例如：
他是我们三个最高的一个。
这个房子是所有房子中最大的一个。
（tall-tallest；big-biggest）
请告诉我您如何构成比较级和最高级？
这是必须知道的！
第一种情况：如图所示：

第二种情况：一些双音节和多音节单词的比较级在原级前加 more，最高级在原级前加 most
beautiful—more beautiful—most beautiful
interesting—
difficult—
第三种情况：规则不规则变化的形容词:
little （原形） – less （比较级）- least（最高级）
good/well（原形） – better（比较级） – best（最高级）
bad/ill （原形） – worse（比较级） – worst（最高级）
far （原形）– further—furthest
many/much——more——most
few——fewer——fewest
示例展示：
Tom is tall. John is tall. Bob is tall.
I’m as tall as you. Tom is as tall as John.
A as+形容词或者副词原形+as B 这是原级比较，
Bob is taller than John.
John is the tallest of the three.
John is the tallest in his class.
常见的用法如下
一、 在…than…句中，这是常见的比较级用法
He is taller than I.（口语中常作：He is taller than me.）
他比我高。
He is two heads taller than I.
他比我高出两个头。
二、 比较级and比较级，表示越来越……
It‘s getting darker and darker.
天越来越黑了。
He is getting more and more interestedin sports.
他对体育越来越感兴趣。
备注：如果是多音节的话，用more and more+adj./adv.
More and more beautiful；more and more carefully
三、 The +比较级，the +比较级， 表示越……，越……
The more you eat， the more you want.你越吃越想要。
The earlier you get up ，the more you read.你起的越早，你读的就越多。
四、 在which…or…？句中，表示两者比较
Which is bigger， the sun or the moon？
太阳和月亮，哪一个更大？

五、形容词比较级前可受much，far，a lot，still，no，a little，even，any 修饰，表示超出的程度
1. much
We have a much better life now. 我们现在的日子好得多了。
2. far
