本课时在本单元的作用本课时为语法课，是本单元的第四课时。该板块延续了前一板块的话题，继续讨论健康的生活习惯，并对不良习惯提出相应改变建议，而常用来提出建议的典型结构之一便是用作主语的动词不定式，通过本课时的学习，学生们充分感受和理解语法结构，并能自如地使用所学结构提出改变不良习惯的建议，为下一课时UsingLanguage的学习做了语言的铺垫。

本课时文本分析【What】描述各种健康问题及表达对应建议。【Why】通过该语篇的学习，深化学生对目标语法的理解，为学生运用不定式做主语提供了参照文本。【How】该语篇以对话形式呈现，语言简单，内容贴近学生的日常生活，对话中描述各种熟悉的健康问题，运用不定式做主语提出了相应建议。

学情分析已有基础：学生在初中阶段和本套教材的前面册次已经学习过动词不定式作宾语、宾补、定语、状语等用法，学生在本套教材选择性必修第一册第三单元学习了动词的-ing形式作主语的用法。预设困难：动词不定式做主语的形式、位置和功能以及不定式的复合结构；不定式做主语和动名词做主语的区别；正确运用不定式做主语提出建议。解决办法：依据以语言运用为导向的“形式-意义-使用"三维动态语法观，通过对做主语的动词不定式形式的呈现，关注其形式和位置，通过观察、判断和理解ReadingandThinking中出现的表达建议和陈述事实的做主语的动词不定式，探究其意义，在真实语境中通过比较、分析并总结动词不定式做主语和动名词做主语的区别，最后创造新的语境---求助帖子，引导学生运用所学的动词不定式做主语为对方提出建议，让学生灵活使用所学结构。

教学重难点教学重点：引导学生结合真实语境理解动词不定式做主语的形式、位置和功能。教学难点：指导学生运用动词不定式做主语提出改变不良习惯的建议。

评价内容与标准评价内容：理解动词不定式做主语的意义和功能并在语境中正确使用。评价标准：能否结合语境准确使用动词不定式做主语提出建议。
