形容词比较级（1）
1. 形容词比较级的概念
英语的大部分形容词通常用三种形式来表达事物的等级差别，分别是原级、比较级（意为“比……更……”）、最高级（意为“最……”）。本模块我们先来一起学习形容词的比较级的用法。当表示对两者（人或事物）的性质进行比较时，就要用形容词比较级的形式。
项目 构成方法 原级 比较级
单音节和少数
双音节形容词 一般在形容词原级的词尾加-er deep, high,
great, tall deeper, higher, greater, taller
以字母e结尾的形容词，在词尾直接加-r nice, fine, large nicer, finer, larger
2. 形容词比较级的构成单音节和少数双音节形容词比较级变化规律如下：
以重读闭音节结尾，且末尾只有一个辅音字母的形容词，应先双写该辅音字母，再加-er thin, big, hot thinner, bigger, hotter
以“辅音字母＋y”结尾的形容词，先把y改为i，再加-er early, easy,
busy, heavy earlier, easier, busier, heavier
巧记口诀
比较级，很好记。一般直接加-er；以e结尾只加-r；遇到一元一辅重读闭音节，末尾字母要双写。
3. 形容词比较级的用法
（1）“A+be+形容词比较级+than+B”意为“A比B更……”。如：
He is younger than me.他比我年轻。
（2）“比较级+and+比较级”意为“越来越……”。如：It’s getting colder and colder. 天气变得越来越冷了。
（3）“比较级+than+any other+单数可数名词”意为“比别的任何一个都……”。如：
China is larger than any other country in Asia. 中国比亚洲其他任何一个国家都大。
（4）“Who / Which+谓语+比较级，A or B ” 意为“A和B，哪个 / 谁更……”。如：Who is taller, Jim or Tom 吉姆和汤姆，谁更高？
（5）“the+比较级，the+比较级”意为“越……，就越……”。如：
The more I read, the happier I will be. 我读的书越多，就越高兴。
（6）“the+比较级+of the two”用于两者之间的比较，强调其中一个（人或物），表示特指，比较级前要加定冠词the。如：
Mary is the younger of the two girls. 玛丽是这两个女孩中年纪较小的那个。
4. 比较级前的修饰语
英语中常用来修饰比较级的单词或短语有：a little，a bit，a few，a lot，much，even，far，still，rather， any等；而too, very, quite修饰原级。如：
I feel even worse now. 现在我感到更糟糕了。
It is much colder today than yesterday. 今天比昨天还要冷得多。
