课后反思:本单元属于读写课，以复习谈论学生最喜欢的食物和健康食物来导入新课文的学习,因此能很好地利用这个话题来开展各种教学活动，紧密联系学生的生活实际，帮助学生增进对健康食品的了解，培养其健康的饮食习惯。在本节课的教学设计环节中，还应注意以下几点：
1、应该鼓励学生有自信地开口说英语，教师还可以鼓励学生多用之前所学的词汇短语进行描述，不要局限于教材中的短语词汇。
2、教师可通过教材泛听，静听，跟读等方法反复让学生加深对文章的理解，进而学习其中的知识点。还可以通过采用例句记忆和背诵课文的方式掌握知识点。同时，教师要引导学生捕捉关于健康饮食的信息，帮助学生培养健康饮食的意识。
3，在课堂上要多鼓励学生多讲英语，采用朗读表演，情景对话，分组讨论等方法，让学生尽可能多的参与课堂讨论。
