小学英语比较级用法
小学英语比较级是教学的一个难点,特别是小学英语比较级的用法,小学生很难掌握。下面,详细为同学们讲解一下小学英语比较级用法。
当我们需要对事物作出比较时,需要用到比较级。
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。)
形容词的比较级是在形容词的基础上变化而来的,它的变化规则是:
(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 – funnier
(4) 双写最后的字母再加er,如big – bigger, thin – thinner ,hot – hotter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的,
如:many / much(原形)– more(比较级)– most(最高级)
little / few(原形) – ;; less (比较级)– 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
附加: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)
注意: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.
附: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。)
