形容词比较级一、形容词比较等级的构成：英语形容词比较等级有三个：原级，比较级和最高级。

形容词比较等级形式变化有规则的和不规则的两种。

规则变化1）单音节词末尾加-er（比较级），-est（最高级）【例】原级比较级最高级great greater greatestsmall smaller smallestclean cleaner cleanest2）单音节如以e结尾，只加-r（比较级），-st（最高级）【例】fine finer finestnice nicer nicestwide wider widest3）闭音节单音节词如末尾只有一个辅音字母，须先双写这个辅音字母，再加-er（比较级），-est（最高级）【例】big bigger biggesthot hotter hottestred redder reddest4）少数以-y，-er，ow，-ble结尾的双音节词，末尾加-er（比较级），-est（最高级）。

以-y结尾的词，如-y前是辅音字母，则变y为-i，再加-er和-est。

以-e结尾的词只加-r和-st。

【例】clever cleverer cleverestnarrow narrower narrowestable abler ablesteasy easier easiest5）其它双音节和多音节词皆在前面加单词more和most。

【例】careful more careful most carefuldifficult more difficult most difficultdelicious more delicious most delicious不规则变化原级比较级最高级good/well better bestbad worse worstmany/much more mostlittle less leastfar farther/further farthest/furthest注：有些形容词一般没有比较等级。

如： right, wrong, woolen等。

二、比较等级的修饰语强调比较程度时，形容词(副词)前一般可加上too，very，so，quite等。

比较级前则要加上much, even, a little, a lot, still, a bit等词(组)表示程度。

如：This box is a bit heavier.比较级前常见的修饰语可分以下四类：①表示强调的修饰语：still, quite a bit, even, nearly, rather等。

②表示程度强、深的修饰语：much, a lot等。

③表示程度弱、轻的修饰语：a bit, a little等。

④表示数目、量的修饰语：twice, four times等。

三、比较等级的用法(1)比较级用于二者的比较，表示其中一个比另一个"更……"，后面than连接另一个所比较的人或物。

单词than的后面无论接什么词，than前面的形容词(副词)均应用比较级形式。

有时，在下文明确的情况下，形容词(副词)比较级也可单独使用。

如：He is much taller than me.Lesson 4 is easy. But Lesson 5 is easier.(2)在使用比较级时，必须是同类事物的比较。

否则会造成歧义。

如：His hat is a little bigger than yours. (这里yours相当于your hat,不能用you)(3)比较级的要避免自己与自己比较。

如：Mary is taller than any other student in her class.(4)形容词最高级形式前要加定冠词，后面要用介词of或in的表示范围的短语。

最高级的主语要在比较范围之内。

如：This bike is the newest of all.(5)形容词(副词)的比较级和最高级句型有时可互换使用。

如：Unit 3 is the easiest of all in the book. = Unit 3 is easier than any other one in the book.I. 形容词比较级练习1. Bob never does his homework___ Mary.
