比较级& 最高级比较级:一、形容词的比较级1、形容词比较级在句子中的运用：两个事物或人的比较用比较级，比较级后面一般带有单词than。
比较级的句子结构通常是：什么 + 动词be (am , is , are ) + 形容词比较级 + than（比）+ 什么 ,如：I'm taller and heavier than you. （我比你更高和更重。
）An elephant is bigger than a tiger. （一只大象比一只老虎更大。
）比较级前面可以用more, a little 来修饰表示程度。
than后的人称代词用主格（口语中可用宾格）。
2．形容词加er的规则：① 一般的直接在词尾加er ，如 tall - taller , strong - stronger ,② 以e结尾的，直接加r ，如 fine - finer ,③ 以辅音字母加y结尾的，先改y为i再加er，如funny - funnier④以一个元音字母和一个辅音字母结尾，双写最后的字母再加er，如big--bigger, thin--thinner ,hot–-hotter， sad--sadder，fat—fatter3．不规则形容词比较级：good--better, many/ much ----morebeautiful--more beautiful， expensive--more expensive二、副词的比较级1．形容词与副词的区别 (有be用形，有形用be；有动用副，有副用动)⑴在句子中形容词一般处于名词之前或be动词之后。
⑵副词在句子中最常见的是处于实义动词之后。
2．副词比较级的变化规则基本与形容词比较级相同☆注意☆1、比较的两者应该是互相对应的可比较的东西。
典型错误：My hair is longer than you.（我的头发比你更长。
）比较的两者是我的头发、你（整个人），那么比较的对象就没有可比性。
应该改为：My hair is longer than yours. 或My hair is longer than your hair.2、如果比较的两者是一样的时候，我们会用as…as…这个词组。
它的用法是：什么+be+as+形容词原形+as+什么，意思是什么和什么一样……。
如：I'm as tall as you.（我和你一样高。
）My feet are as big as yours.（我的脚和你的一样大。
）最高级：一、形容词的最高级变化类似于比较级，只是把词尾的er改成est，如：tall （原形）- taller （比较级）- tallest （最高级）long（原形）- longer（比较级）- longest（最高级）big （原形）- bigger（比较级）- biggest（最高级）few (原形) –fewer（比较级）--fewest（最高级）二、除此之外，还有几个特殊的单词，它的比较级和最高级都是不规则。
如：many / much（原形）- more（比较级）- most（最高级）little （原形） - less （比较级）- least（最高级）good（原形）/well - better（比较级） - best（最高级）bad （原形）/badly - worse（比较级） - worst（最高级）far（原形）-- farther（比较级）—farthest（最高级）further（比较级）-- furthest（最高级）巩固练习old__________ young________ tall_______ long________short________ strong________ big________ small_______fat_________ thin__________ heavy______ light________ nice_________ good_________ beautiful__________________low__________ high_________ slow_______ fast________late__________ early_________ far_________ well_______练习一、请写出下列形容词的比较级和最高级。
