形容词：比较级
形容词的比较级用于两者之间的比较，表示“更……”。
一、比较级的构成规则
1. 一般情况下，在词尾加“-er”。
例如：tall（高的）→ taller；short（矮的）→ shorter；fast（快的）→ faster。
2. 以不发音的字母 e 结尾的词，直接加“-r”。
例如：nice（好的）→ nicer；fine（好的）→ finer；large（大的）→ larger。
3. 重读闭音节词，双写末尾辅音字母再加“-er”。
例如：big（大的）→ bigger；hot（热的）→ hotter；thin（瘦的）→ thinner。
4. 以“辅音字母 + y”结尾的词，变“y”为“i”再加“-er”。
例如：heavy（重的）→ heavier；happy（快乐的）→ happier；busy（忙碌的）→ busier。
5. 多音节词和部分双音节词，在词前加“more”。
例如：beautiful（美丽的）→ more beautiful；important（重要的）→ more important；interesting（有趣的）→ more interesting。
二、比较级的用法
1. “A + be + 形容词比较级 + than + B”，表示“A 比 B 更……”。
例如：This book is more interesting than that one.（这本书比那本书更有趣。）
He is taller than me.（他比我高。）
2. “比较级 + and + 比较级”，表示“越来越……”。
例如：It's getting colder and colder.（天气越来越冷了。）
The girl is becoming more and more beautiful.（这个女孩越来越漂亮了。）
3. “the + 比较级，the + 比较级”，表示“越……，就越……”。
例如：The more you read, the more you know.（你读得越多，知道得就越多。）
The harder you study, the better grades you will get.（你学习越努力，成绩就会越好。）
三、比较级的特殊用法
1. 比较级前可以用 much、a little、a lot、even、far 等副词修饰，表示程度的加深。
例如：He is much taller than me.（他比我高得多。）
This book is a little more interesting than that one.（这本书比那本书稍微有趣一点。）
2. 比较级可以和“of the two”连用，表示“两者中较……的一个”。
例如：He is the taller of the two boys.（他是两个男孩中较高的一个。）
This book is the more interesting of the two.（这本书是两本书中较有趣的一本。）
3. 比较级可以和“any other + 单数名词”连用，表示“比任何其他的……都……”，这种结构通常用于同一范围内的比较。
例如：China is larger than any other country in Asia.（中国比亚洲任何其他国家都大。）
He is taller than any other student in his class.（他比他班上任何其他学生都高。）
