Teaching
purpose
歌曲热身，激发学生的学习兴趣。教师以谈话方式导入，延续“农场”这个话题。利用PPT出示情景图，通过谈论图片复习上节课所学内容，并为接下来的学习做好铺垫。
Teaching
purpose
教师通过复习上节课内容引出新单词“carrots”，借助图片教授新单词，并用数数的方式帮助学生关注其复数形式。
Teaching
purpose
教师利用PPT帮助学生对比两种不同颜色的西红柿，做示范性描述并引导学生用句型“Look
at…
They\'re…”来描述蔬菜特征。
Teaching
purpose
利用刚学过的“tomato”来学习“potato”，可以帮助学生很快地掌握新单词的读音和词形。将PPT出示的土豆图片与书中土豆的图片进行对比，再次引导学生用句型“They\'re…”
来描述蔬菜特征。
Teaching
purpose
利用“green”引导学生尝试自己拼读“bean”，充分调动学生的学习主动性，注重学生学习方法的培养。
Teaching
purpose
先看图说单词，再用小游戏的形式进行操练，充分调动学生的多种感官，既活跃了课堂气氛，又加强了学生对新学单词的记忆。
Teaching
purpose
继续操练新单词，通过有节奏的chant使学生在朗读句子中熟悉核心词汇。开放性练习有助于培养学生的发散性思维。
Teaching
purpose
通过创设自然真实的情境，让学生在情境中合理运用所学词汇，培养学生的综合语言运用能力，并在这个环节中让学生体会“多吃蔬菜有益于我们的身体健康”的观念，适时进行情感态度价值观的渗透。
