知识要点
1)英语中大多数形容词、副词是可以分等级的，一般有三个等级：原级，比较级和最高级。形容词、副词的本来形式就是形容词的原级。如：John is a tall boy.两者间进行比较用到形容词比较级。如：Jim is taller than John.三者或者三者以上进行比较用形容词的最高级。Mike is the tallest of the three boys.(形容词最高级前面要加定冠词the)
2).形容词、副词比较级和最高级有规则变化和不规则变化
规则变化
①单音节或双音节的形容词（或副词）比较级＋er最高级＋est small－smaller－smallest等
②以e结尾的词，比较级＋r，最高级＋st即可nice－nicer－nicest
③以辅音字母＋y结尾的，变y为i＋er或est easy－easier－easiest
④双写最后一个辅音字母＋er或est hot－hotter－hottest
⑥一些双音节及多音节形容词或副词前要加more和most，如：
difficult---more difficult---most difficult
不规则变化：
good/well－better－best,bad－worse－worst many/much－more－most little－less－least
far－further －furthest（表示程度） far－farther－farthest（表示远近） old－older－oldest（表新旧） old－elder－eldest（表兄弟姊妹之间的长幼）
3).比较级前的修饰词：a little, a lot, much, even; far; still
4)形容词、副词比较级的特殊用法
①形容词/副词比较级+than+ any other+单数名词(+介词短语)"表示"比同一范围的任何一个人/物都……"，含义是"最……"。
例如，Mike gets to school earlier than any other student in his class.
= Mike gets to school earlier than any of the other students in his class. = Mike gets to school earlier than the other students in his class. = Mike gets to school earliest in his class.注意：Mike gets to school earlier than any student in Tom's class.
②"the+形容词比较级+of the two+……"表示"...是两者中较…的"。
如，Look at the two boys. My brother is the taller of the two.
③"比较级+and+比较级"表示"越来越……"。He is getting taller and taller.
④"the+比较级，the+比较级"表示"越…,越…,"。The more careful you are，the fewer mistakes you'll make
5).最高级常用句型结构
①"主语+be+ the+形容词最高级+单数名词+in/of短语"表示"……是……中最……的"。
如，Tom is the tallest in his class./of all the students.
②"主语+be+ one of the+形容词最高级+复数名词+in/of短语"表示"…是……中最……之一"。
如，Beijing is one of the largest cities in China.
③序数词+最高级
Hainan Island is the second largest island in China.
