形容词副词的比较级与最高级
一. 定义
比较级comparative degree 在英语中通常用下列方式表示的词：在形容词或副词前加more(如 more natural,more clearly )或加后缀 -er(newer,sooner )。典型的是指形容词或副词所表示的质、量或关系的增加。英语句子中，将比较两个主体的方法叫做“比较句型”。其中，像“A比B更……”的表达方式称为比较级。组成句子的方式是将形容词或副词变化成比较级的形态。

二.形容词、副词比较级和最高级有规则变化和不规则变化
（1）一般情况下，单音节或双音节的形容词（或副词）比较级＋er 最高级＋est
clever－cleverer－cleverest few－fewer－fewest small－smaller－smallest等
（2）以e结尾的词，比较级＋r，最高级＋st即可
nice－nicer－nicest cute－cuter－cutest large－larger－largest
（3）以辅音字母＋y结尾的变y为i＋er或est
easy－easier－easiest happy－happier－happiest
再如：early , busy , heavy , dirty , lazy . 也如此
（4）双写最后一个辅音字母＋er或est的词同学要用心去记。
1. fat－fatter－fattest 2. thin－thinner－thinnest
3. hot－hotter－hottest 4. big－bigger－biggest
（5）多音节和部分双音节的词需要在形容词原级前＋more构成比较级,＋the most构成最高级。 beautiful －more beautiful － the most beautiful .
delicious , popular , important , interesting , expensive
双音节的词如
careful－more careful －the most careful
useful －more useful －the most useful .
少数单音节词也是这样如：
pleased－more pleased －the most pleased
tired－more tried －the most tired

.
