本单元的教学内容围绕“多久做一次运动”这一话题展开。

Section A是基本语言内容的收集和学习，这一部分引导学生通过本课的语言素材进行看图说话、句型演练、实际描述，通过对话表演等使学生能够正确地使用表示做什么活动的词组，多久做一次的句型，从而熟练地谈论多久做一次活动。

Section B是知识的扩展和语言的综合运用，是在Section A的基础上，锻炼学生能够自如地谈论自己的生活习惯。

这些内容都是与学生日常生活紧密相关的，学生很熟悉，也乐于去说，因此在这一课题的教学过程中，应紧密联系学生生活实际，采用多种方式，以说为主，配合听的练习，最终以对话为途径，解决本课题的中心语句。

这易于引发学生学会运用简单的英语进行交际和交流，也对提高学生的综合能力，特别是说的能力很有帮助。

学生通过对本单元的学习，可以引导他们养成良好的生活习惯和饮食习惯，从而合理安排自己的各项工作，享受丰富多彩的校园生活。
