(2)形容词和副词比较级的定义。 ① 形容词比较级：用于人或物两者进行比较时，表示“更……”。句中通常有than, much, a little, A or B这些关键词句。 ② 副词比较级：用于动作的比较，通常与动词共同使用，表示“更……”。副词和形容词可以合并在一起进行比较区分 (3)形容词与副词比较级的构成规律：构成法原级比较级一般在形容词或副词后加er tall，high taller, higher 结尾有e的直接加r nice, late nicer, later 重读闭音节单词，需要双写最后的辅音字母，再加-er big, thin, fat, hot, red bigger, thinner, fatter, hotter, redder 以辅音字母加y结尾的词，变y为i，再加-er heavy, early, happy, busy heavier, earlier, happier, busier 有些形容词和副词的比较级是不规则的，如: good/ well ---better, far---farther, many/ much-more (4)形容词比较级句子的结构是：句型的列举不要用公式的形式来表达 …+be+形容词比较级+than+… 例：Mike is shorter than her. My pencils are longer than theirs. (5)副词比较级句子结构（以一般现在时为例）： …+行为动词(s/es)+副词比较级+than+… 例如：肯定句：Helen sings better than Mike. The girls sing better than the boys. 否定句：Helen doesn't sing better than Mike. The girls don't sing better than the boys. 一般疑问句： Does Helen sing better than Mike? Do the girls sing better than the boys? (6)形容词比较级与副词比较级的区分： ①比较对象不同：形容词比较级用于比较人或物，副词比较级用于比较动作。 ②动词搭配不同：形容词比较级搭配be动词，My mother is taller than my sister. 副词比较级搭配行为动词，My mother runs faster than my sister. (7) tall 指身高，high 指动作做得高 big, small指体积的大小，old, young指年龄的大小。 good 修饰名词，指事物好，well 修饰动词，指动作做得好。在这两类词的列举中要在简单省略点 3.预习自测：一、句型转换。 1. Tom is taller than his classmates.
