"越来越..."结构：比较级 + and + 比较级 The weather is getting colder and colder. "越...就越..."结构：The + 比较级, the + 比较级 The more you practice, the better you will be. 五、易错点突破 比较对象不一致 My hair is longer than my sister. My hair is longer than my sister's. 双音节词的特殊变化 以-y, -er, -ow, -le结尾的双音节词通常加-er： happy → happier 其他双音节词多用more： modern → more modern 最高级需加范围 She is the smartest. She is the smartest in her class. 六、记忆口诀 "比较级，比高低，单音节词加-er； 辅音+y要变i，重读闭音双写记； 多音节词不用愁，more/most放前就可以； 不规则变化特殊记，good变better别忘记！" 1． the mountain is, the air is.
