形容词的比较级
1.含义
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。
(1)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 。 (2)形容词的比较级:
形容词的比较级表示“更……\",用于两者之间的比较,用来说明“前者比后者更……\",比较级前面一般用much, even, a little,a lot修饰,其中even, much 只能修饰比较级。 2。形容词比较级的构成:
类别 构成方法 原级 比较级 一般直接加—er long longer tall taller 不发音的e结尾时加—r late later large larger 单音节词和少数双音节辅音字母加y结尾时把yeasy easier 词 变i,再加—er happy happier 重读闭音节结尾并且只big bigger 有一个辅音字母时,双写hot hotter 最后的辅音字母,再加-er fat/thin fatter/thinne形容词的比较级
单音r 节词和节词:
少数双音
多音节词和部分双音节词:
类别 构成方法 原级 比较级 more careful more beautiful less important less useful 多音节词和部分在原级前加more careful 双音节词 beautiful 在原级前加less important useful 少数不规则变化: good→better bad→worse far→farther many/much→more little→less 等 3.形容词比较级的用法: (1)当两个人或事物(A和B)进行比较时,我们需要用到形容词的原级或者比较级 ①表达“A大于B”用“比较级+than”的结构。 公式:A+be动词+形容词比较级+than+B… I am taller than you.我比你高. ②表达“A和B一样”,用as…as的结构。 公式: A+be动词+as+形容词原级+as…+B I am as tall as you.我和你一样高. ③表达“A不如B\"用not as/so…as的结构。 公式:A+be动词的否定形式+as+形容词原级+as…+B 形容词的比较级
I am not as tall as you。我没有你高。 ④“比较级+and+比较级”表示“越来越……”。 It is getting warmer and warmer.天气越来越暖和。 He is running faster and faster.他跑得越来越快。 ⑤“the more…, the more…”表示“越……,就越……\The more,the better。多多益善。
The more careful you are,the fewer mistakes you will make.你越细心,犯错就越少。 ⑥表示“两个中比较……的:the + 比较级+ of the two He is the better of the two 。 他是这两个人中比较好的.
(2) 关于形容词比较级的更多用法
①比较级前面可以加上表示具体数量差别的结构,表示具体“大多少”,“小多少”,“长多少”,“短多少\"等。
I am two years older than he。我比他大两岁.
This building is 20 meters higher than that one。这个建筑物比那个高20米.
