(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。) 比较级专项练习 一、从方框中选出合适的单词完成句子 heavy tall long much many big (1) How ____ is the Yellow River? (2) How_____ is Mr Green? He’s 175cm. (3) How____are your feet? I wear size 18. (4) How ____ is the white T-shirt? It’s 100 yuan. (5) How ____ apples are there in the bag? There are 5.
