1、小学英语:形容词、副词比较级一、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: Im 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: 一般的直接在
2、词尾加er ,如 tall - taller , strong - stronger , 以e结尾的,直接加r ,如 fine - finer , 以辅音字母加y结尾的,先改y为i再加er,如funny funnier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,fatfatter3不规则形容词比较级: good-better,beautiful-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
3、be;有动用副,有副用动)在句子中形容词一般处于名词之前或be动词之后。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 asas这个词组。它的用法是:什么+be+as+形容词原形+as
4、+什么,意思是什么和什么一样。如: Im 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:二、 tall (原形)- taller (比较级)三、 long(原形)- longer(比较级)四、 big (原形)- bigger(比较级)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 / few(原形) - less (比较级)-
5、 least(最高级)good(原形) - better(比较级) - best(最高级)bad (原形) - worse(比较级) - worst(最高级)far (原形)- further- furthest练习:一、 写出下列形容词或副词的比较级old_ young_ tall_ long_short_ strong_ big_ small_fat_ thin_ heavy_ light_nice_ good_ beautiful_low_ high_ slow_ fast_late_ early_ far_ well_二、根据句意填入单词的正确形式: 1.
