小学英语语法 形容词的比较级

1、比较级& 最高级 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: 一般的直接在词尾

2、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

3、用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+什么

4、,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。 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
