Thoughts on the design: 本课语法教学主要使学生掌握不定式的功能和用法。总体教学思路如下：引用Agony aunt Annie给Sarah和Andrew的回信引出不定式的概念和基本构成；学生在教师的鼓励下，找出信中所有的不定式结构，并在老师的指导下，总结归纳不定式在句中的不同功能；采用游戏“传声筒”引出学生对不定式不同构成的思考和总结概括；采用竞赛方式鼓励学生在探讨友谊的同时适当运用不定式结构并同时引出Bare infinitive的概念和规则；在最后的运用环节，学生通过完成Sarah给Annie的感谢信，在具体的情境中，操练本课所学的不定式的用法。 Teaching aims: Students will find out and learn the functions of To-infinitive in a sentence and its different forms by involving themselves in different activities, games and competitions; Students will know how to use Bare infinitive; Students will further learn how to get along well with friends. Teaching important points and difficult points: To master the function of to-infinitive To know how to use Bare infinitive; Teaching procedures: Step 1 lead in (PPT 4-7) Teacher reminds students of the letters that Agony Aunt Annie wrote to Sarah and Andrew.

(to do as object complement of a sentence) Students are asked to pay attention to the parts in bold, and thus To-infinitive is introduced.

Ss are asked to study the two letters on Page 5 again, this time trying to find out more To-infinitives in the letters and tell their functions in the sentences.
