比较级和最高级 1.形容词和副词有原级、比较级和最高级。原来的形式称为原级,表示“比较……”的称为比较级,表示“最……"的称为最高级。形容词和副词的比较级和最高级的变化方法如下: (1)符合规则的: 情 况 加 法 例 词 small- smaller- 一般情况 直接加-er;—est smallest fast—faster-fastest nice—nicer—nicest 以不发音的e结直接加—r;—st 尾的词 st dry-drier-driest lazy-lazier—laziest 以“辅音字母+y”变y为i再加—er;结尾的词 —est t; heavy—heavier-heaviest thin—thinner-thinne以一个辅音字母辅音字母双写再加结尾的重读闭音—er;-est 节词 hot—hotter-hottest important—more important—most important interesting—more 多音节词和部分双音节词 在单词前面加more和most interesting—most interesting convenient—more convenient-most convenient (2)不规则的形容词和副词的比较级和最高级如下表: big-bigger-biggest st easy—easier—easieslarge—larger—large比较级和最高级 原级 good/wel比较级 最高级 better l bad/ill many/mucmore h little far best worse worst most less farther/further least farthest/furthest (2)形容词和副词的比较级的用法如下: ①在表示程度相同时,用“as+形容词或副词的原级+as+比较状语从句"句型。例如: Jim is as tall as his brother. Bruce didn't come to the classroom as early as Dick yesterday. ②在表示一方不如另一方时,“not as /so+形容词或副词的原级+as+比较状语从句"句型。例如: Lesson Three is not so easy as Lesson Two.It's much more difficult.第三课不如第二课简单,它难一些. ③在表示一方超过另一方时,要用“形容词或副词比较级+ than +比较状语从句”句型。例如: Peter is fatter than his brother. ④在表示三个或三个以上的人或事物中程度最高时,用句型“the +形容词或副词的最高级(+名词)+in /of /among(名词的复数形式或代词的宾格)",副词的最高级前面的the可以省略。例如: Which do you like best,tea,orange juice or water? Of all stars,the sun is the nearest to the earth.所有星体中,太阳离地球是最近的。 —Which is the hottest season of the year? -Summer. —一年中哪一个季节最热? -夏季。 ⑤有些形容词由于受本身涵义的限制,没有比较级和最高级。如:dead,empty,round(圆的),sure,woolen等。例如: This bottle is empty.There's no water in it. ⑥形容词比较级前面常用much,far,even,a lot,a little等词修饰。例如: I am a little stronger than you.我比你强壮一点儿。 This street is much straighter than that one.这条路比那条直的多。 In this country,it’s very cold in November,but it’s even colder in December. (3)级别之间的转换 ①原级与比较级之间的转换 A.倍数+as...as→倍数+比较级+than.例如: This book is twice as thick as that one.→ This book is once thicker than that one. 本文来源:https://www.dywdw.cn/44edb9faa4c30c22590102020740be1e640eccba.html
