专题：形容词、副词的比较级和最高级一、形容词、副词比较级和最高级的意义英语中的形容词和副词，在句子里表示“比较……”、“最……”时，要用特别的形式，即：比较级和最高级。

原来的形式称为原级。

如：long longer longest原级比较级最高级1．The black pen is very long. 黑色的钢笔很长。

2．The blue pen is longer than the black one. 蓝色的钢笔比黑色的长。

3．The red pen is the longest of the three. 红色的钢笔是三支中最长的。

二、形容词、副词比较级的用法表示两者间的比较用比较级。

其常见句式有：1．“A + be +形容词比较级+ than + B”意思为“A比B更……”。

如：This tree is taller than that one. 这棵树比那棵树高。

注意：①在含有连词than的比较级中，前后的比较对象必须是同一范畴，即同类事物之间的比较。

②在比较级前面使用much，表示程度程度“强得多”。

如：A watermelon is much bigger than an apple.③very, quite一般只能修饰原级，不能修饰比较级。

2．“become + 形容词比较级+ and + 形容词比较级”是“变得越来越……”的意思，and连接同一个形容词的比较级。

如：It becomes warmer and warmer when spring comes. 春天来了，天气变得越来越暖和了。

注：表示“越来越……”时，若比较级是“原级+ er”构成的，则常用“比较级+ and + 比较级”形式；若比较级是“more + 原级”构成的，需用“more and more + 原级形式”。

如：Our school is becoming more and more beautiful. 我们的学校变得越来越美丽。

3．在含有or的选择疑问句中，如果有两者供选择，前面的形容词要用比较级形式。

如：Who is taller,Tim or Tom? 谁更高，Tim还是Tom?三、形容词、副词的最高级的用法形容词、副词的最高级形式主要用来表示三者或三者以上人或事物的比较，表示“最……”的意思。

句子中有表示范围的词或短语。

如：of the three, in our class等等。

如：He is the tallest in our class. 他在我们班里是最高的。

四、注意形容词最高级前一定要有定冠词the，而副词最高级前则不需要。

五、形容词、副词的比较级和最高级的构成规则1．一般情况下，比较级在后面加-er，最高级在后面加-est；如：small→smaller→smallest short→short er→shortest2．在重读闭音节（即：辅音＋元音＋辅音）中，先双写末尾的辅音字母，比较级加-er，最高级加-est；如：big→bigger→biggest hot→hott er→hottest3．以不发音e结尾的单音节词，比较在原级后加-r，最高级在原级后加-st；如：large→larger→largest nice→nicer→nicest4．以“辅音字母＋y”结尾的双音节词，把y改为i，比较级加-er，最高级加-est；如：easy→easier→easiest heavy→heavier→heaviest5．多数多音节词，比较级在前面加more，最高级在前面加most；如：beautiful→more beautiful→most beautifuldifferent→more different→most different6．有少数形容词、副词的比较级和最高级是不规则的，必须熟记。
