Unit 2 Keeping Healthy
Topic 2 I must ask him to give up smoking.
教学内容分析及课时分配建议：
本单元以Keeping Healthy 为主题。话题二主要学习有关个人卫生和饮食健康等内容。Section A部分通过谈论健康的生活习惯学习情态动词must及其否定形式 mustn’t表示必要性的用法，如You must brush your teeth twice a day. 和You mustn’t read in the sun.等。Section B部分通过对吸烟有害健康的讨论，呈现一些重要句型和词汇，比如You’d better not read in the sun.，give up等，并进一步学习情态动词had better,can,must和may的用法。同时穿插语音学习板块，学习掌握/ʌ/,/a:/ /ɒ/的发音以及辅音加元音的连读。Section C部分通过阅读有关饮食健康的文章复习巩固情态动词must/mustn’t/may/can的同时学会运用简单的阅读策略获取信息和学会保持良好的习惯。Section D部分是对本话题的总结和复习，最后以Project探究活动形式对所学内容进行运用，培养学生的综合语言运用能力。
