教学热身是英语课堂TPR教学法的重要形式之一。说单词做动作，以及找反义词是为学新知识做铺垫。Chant能营造一种轻松欢快的课堂气氛，拉进师生间的距离。
把单词带到情景中学习，学生既学习了单词，又知道如何去运用。在操练单词时，采取全班，组，个人的形式，增加了师生间的互动，全体，个体兼顾。
在学生了解了形容词比较级的句子结构后，在运用到现实生活中加以巩固。
边说歌谣边做动作，使学生对形容词比较级有了更直观的体会，而且歌谣能让学生在轻松愉快的的环境下操练新句型。
无论比较高矮还是年龄大小等，始终在班上同学之间进行，在真实的情境中操练，学生更乐于比较，更容易掌握新句型。
对形容词比较级的基本构成法进行小结十分重要，积累知识为以后的操练打下基础。
学生在前面的反复操练中，已经掌握了比较级句型结构，学习课文会比较轻松。
将课文编成chant，提炼了重点句型，减轻了负担。
