形容词比较级知识详解
一．形容词比较级的变化
1. 规则变化
（1）在形容词后直接加-er。如：tall-----taller，short------shorter等。
（2）以不发音的字母e结尾的只需在末尾加-r。如：nice------nicer，large-------larger等。
（3）以“辅音字母+y”结尾的形容词，要先把y变成i，然后再加-er。
如：heavy------heavier，happy------happier等。
（4）若以重读闭音节结尾且只有一个辅音字母，先双写这个辅音字母，然后再加-er。
如：fat------fatter，big---bigger, thin---thinner,hot------hotter， wet---wetter, sad---sadder,red---redder等。
（5）多音节和部分双音节的形容词，可不是在u末尾变化，而是在前面加more。
如：careful-----more careful，rious-------more rious, fun---more fun等。
2. 不规则变化
good /well------better, bad /badly-------wor, many /much-------more,little------less
二．形容词比较级的用法
在描述单个的某人或某物所具有的特征时，需要用形容词原级形式，当把两者进行比较时，就用比较级，常见的表示这类用法的句型有：
1.“A+be+比较级+than+B”表示“A比B更…”。如：
This book is funnier than that one. 这本书比那本书更有趣。
2.“Which /Who()+be+比较级, A or B?”意思是“A和B，哪个更…….”。如：
Which is bigger, the sun or the earth? 太阳和地球，哪个更大？
Who bag is heavier, yours or mine? 谁的包重些，你的还是我的？
3.“A+be+the+比较级+of the two(……)”意思是“A是两者中较…….的一个。”这时前面一定要加the，表示特指。如：
Lily is the taller of the twins. 莉莉是双胞胎中个子较高的那个。
4. “A+be+less+原级+than+B”表示“A比B更不…”。如：
This book is not funny. But that book is less funny. 这本书不有趣，那本书更不有趣。
三．常与比较级连用的词
1. 前面可以加上a little，a lot，much，even，still等程度副词作修饰语。如：
She is much more careful than her brother. 她比她哥哥细心多了。
2. 前面还可以加表示数量、倍数的修饰语。如：
My brother is two years older than I. 我哥哥比我大两岁。
This room is twice bigger than that one. 这个房间比那个房间大两倍。
四．使用比较级应注意的问题
1. 避免比较对象的不相同。如：
[误]My schoolbag is newer than you.
[正]My schoolbag is newer than yours.
2. 避免与自身相比。如：
[误]Shanghai is bigger than all the cities in China.
[正]Shanghai is bigger than all the other cities in China.
3. 避免与原级混淆。如：
Tom is as hard-working as Jim.
Tom is very\really\quite\pretty talented.
