英语形容词比较级和最高级讲解与练习

英语形容词比较级和最高级讲解与练习绝大多数形容词有三种形式,原级,比较级和最高级, 以表示形容词说明的性质在程度上的不同。 形容词的原级: 形容词的原级形式就是词典中出现的形容词的原形。 例如: poor tall great glad bad 形容词的比较级和最高级: 形容词的比较级和最高级形式是在形容词的原级形式的基础上变化的。 分为规则变化和不规则变化。 规则变化如下: 1) 单音节形容词的比较级和最高级形式是在词尾加 -er 和 -est 构成。 great (原级) (比较级) (最高级) 2) 以 -e 结尾的单音节形容词的比较级和最高级是在词尾加 -r 和 -st 构成。 wide (原级) (比较级) (最高级) 3)少数以-er, -ow, - le结尾的双音节形容词的比较级和最高级是在词尾加 -er 和 -est 构成。或者加more，和most来构成。 gentle(原级) (比较级) (最高级) clever(原级) (比较级) (最高级) narrow(原级) (比较级) (最高级) 4) 以 -y 结尾,但 -y 前是辅音字母的形容词的比较级和最高级是改 -y 为i, 加上 -er 和-est 构成. happy (原形) (比较级) (最高级) 5) 以一个辅音字母结尾其前面的元音字母发短元音的形容词的比较级和最高级是双写该辅音字母然后再加 -er和-est。 big (原级) (比较级) (最高级) 6) 双音节和多音节形容词的比较级和最高级需用more 和 most 加在形容词前面来构成。 beautiful (原级) (比较级) (最高级) difficult (原级) (比较级) (最高级) 常用的不规则变化的形容词的比较级和最高级: 原级-比较级-最高级 good/well-better-best many/much-more-most little-less-least bad/ill-worse-worst far-farther, further-farthest, furthest old-older,elder-oldest,eldest形容词前如加 less 和 least 则表示较不和最不 important 重要 less important 较不重要 least important 最不重要 (7) 部分形容词本身表示最高级，因此他们没有比较级和最高级形式： 如，favourite round 形容词原级用法：比较：asas; not as(so)as （1）“A+as+形容词原级+as+B” He is as tall as me. 他和我一样高。 English is as interesting as Chinese. 英文和中文一样有趣。 Youre a boy as good as Tom.=Youre as good a boy as Tom. 你和汤姆是一样好的孩子。（2） 否定句中的结构：“Anot+as/so+形容词原级+as+B” It is not as/so good as what you said. 那没有你说的那么好。形容词比较级的用法: 形容词的比较级用于两个人或事物的比较,其结构形式如下: 主语+谓语(系动词)+ 形容词比较级+than+ 对比成分。 也就是, 含有形容词比较级的主句+than+从句。注意从句常常省去意义上和主句相同的部分, 而只剩下对比的成分。 Our teacher is we are. 我们老师的个子比我们的高。 It is today than it was yesterday. 今天的天气比昨天暖和。 This picture is than that one. 这张照片比那张照片漂亮。形容词最高级的用法: 形容词最高级用于两个以上的人和物进行比较, 其结构形式为: 主语+谓语(系动词)+the+形容词最高级+名词+表示范围的短语或从句。 She is student in her class. 她是班上最好的学生。 Shanghai is one of cities in China. 上海是中国最大城市之一。 This is apple I have ever met. 这是我见到的最大的苹果。 Tom is boy in his basketball team. 汤姆是他们篮球队中个子最高的孩子。 可用来修饰形容词比较级的词： a little,a bit,a lot,a great deal , much,even,still,far,rather,any等修饰：He made much fewer mistakes than I did. He is even richer than I. 重点与难点： （1）表示两者之间进行选择“哪一个更.”时，用句型“which/who is +形容词的比较级，A or B? ”表示。Who is taller,Li Ming or Wang Tao?表示三或三者以上的人或物中进行选择“哪一个最.”时，用句型“which/who is +the +最高级，A ，Bor C? ”表示。Which city is the most beautiful,Beijing,Shanghai or Fuzhou?（2） 如果在两者之间表示“最”时要在比较级前加the，而且还用of the two, of the pair短语： John is the clever of the two boys.
