五、 教学策略分析
1. 创设Go to Peter’s Vegetable Shop这一情景，巧妙地贯穿整节课的教学。
2. 设计Open an International Market 的任务，让学生在真实的任务活动中运用语言，使学生获得开展模拟买卖活动的经验。
3. 在新单词的教学中，充分利用phonics， 通过师生合作，让学生在老师的协助下，根据音素拼写出新单词，加深学生对新单词的印象，培养学生记忆单词的能力，帮助学生减轻单词记忆的负担。
六、 课前准备
学生在课前利用书籍和网络资源等途径，了解英、美等国家居民对于蔬菜的喜好，然后小组讨论定好本节课开的商店以及商品价格，以便本节课高效地进行模拟买卖活动以及文化意识的渗透。
