12、是在其原级后面加上-er或-est。例如：smallsmallersmallestnewnewernewest（2）以重读闭音节结尾的形容词，需要先双写词尾的辅音字母，再加-er或-est。例如：bigbiggerbiggestthinthinnerthinnest（3）以不发音的e结尾的单音节形容词只需在原级后加-r或-st。例如：largelargerlargestnicenicernicest（4）以“辅音字母+y”结尾的形容词，变为比较级和最高级时，先把y变成i，再加-er或-est。例如：easyeasiereasiestheavyheavierheaviest（5）部分双音节形容词
13、和多音节形容词的比较级和最高级的变化形式在下册教材中会进行学习，这册不作要求。 2. 常用的不规则变化的形容词的比较级和最高级的形式列表如下：原级比较级最高级good better best bad worse worst many more most much more most little less least ill worse worst far farther further farthestfurthest 形容词的比较级用于两个人或事物之间的比较，通常与than连用，其结构形式为“主语+谓语（系动词）+形容词的比较级+than+对比成分”；形容词的最高级用于三个或三个以上的人或
14、事物的比较，形容词的最高级前要加定冠词the，常与表示范围的in the class among the world, in the group等这类短语或者句子连用。其结构形式为“主语+谓语（系动词）+the +形容词的最高级（+名词）+表示范围的短语或句子”。例如：The Nile River is longer than the Yellow River. （两者之间比较）The Nile River is the longest in the world. （范围为in the world，不是只有两条河流）Shanghai is one of the biggest cities in China. （范围为in China，不是只有两个城市）【巩固练习】写出下列形容词的比较级和最高级。 1. tall _ _ 2. nice _ _ 3. big _ _ 4. happy _ _ 5. interesting _ _ 6. good _ _ 7. bad
