Lesson 1 A Visit to an Agricultural Park
【教学分析】
课文地位
1．本课是Unit 3的第一课，讲的是一次去农业园区的参观，重点是谈论植物。有条件的学校可以带学生先去某一个农业园区参观，实地认识蔬菜、水果等植物，增加感性认识，让学生认识大自然、体验大自然以及认识到科技知识在现代农业中的作用。教学时可以和六年级第一学期的第三单元Food and Drinks联系起来。
2．本课的语法重点和难点是带疑问词的不定式在句中作宾语以及宾语从句和其重点句型：I don’t think….教师在教学时应加强机械操练和注意创设真实情景让学生体验语法和意境。
【教学目标】
1．掌握一定量的蔬菜、水果等植物的名称来谈论植物。

教学内容 教学实施建议 教学资源参考
Discovering LanguageThe infinitive with wh- words (how, what, when, which, where, whether等)带疑问词的不定式 在语法教学时，应多为学生创设情景，让他们在活动中探索规律，激发学生的探究、创新精神。教师应精讲学生应多练，反复使用，反复操练，通过输入量的不断增加，让学生自己发现语法现象、语法规律，建立一种适合他们的语言习惯。 Listen to the following dialogues.Suppose you are a tour guide.更多练习不定式的成分
A Children’s RhymeNew Words and Tuning In 常言道：良好的开端是成功的一半，所以老师可以让学生唱歌或背谚语等激发起学生潜在学习兴趣。通过Tuning in中的图片或事先准备的PPT及录像等，引出单词及句型。 还可以掌握五组单词：dog---puppycat-- kittencow-calfduck---ducklingsheep---lamb
Text 通过课文的学习，让学生在掌握单词的基础上对宾语从句和时间状语从句有一定的认识，认识其结构和时态的变化。以及掌握带疑问词并在句中作宾语的不定式用法。 重点词汇

【教学准备】
我们经常说兴趣是最好的老师，我们也知道非智力因素可以在学生的学习中起到25%左右的作用。所以，老师和学生的准备可以在一星期前甚至在一开学就可以开始了！
1．布置教室生物角。每一小组种植一样植物，上面有中英文对照的植物名
称。由组员轮流管理和记录浇水和施肥情况，观察它的生长变化。通过这项活动学生能够获得实际经验并美化教室。
2．请每位学生利用课余时间去家附近的水果店或超市，记录水果或蔬菜的
名称并查找出英文。（当然，也可以用上网等别的方式查找。）做成卡片后在教室展示或比赛等，让学生在生活中发现英语，事先有一定的输入量。我认为对一个学语言的人来说，只有大量的输入才有可能有机会输出。
3．针对课文中的英文：organic vegetable，事先提出问题：什么是有机
蔬菜？（对知识面较广的同学提出问题：什么是绿色食物？）希望学生在寻找答案过程中发现环境和植物的关系，并且知道什么是对人类有好处的健康食物、怎样保护好环境，怎样使人类和动植物和谐相处。
4．有条件的学校可以建立校园暖棚或小小植物园，可以让学生经常去观察
和体验。
5．建立学校的植物名册录。
希望老师在每一节课的前五分钟给学生一个兴奋点、一种期待。如果老师手捧一束鲜花，或拿着种在贝壳里的洋葱进教室，你是否能发现洋溢在学生脸上的笑容呢？
鲜花 Look, do you know what they are
(Of course, they are flowers. / They are lilies.)
Yes, you know they are lilies. But do you know whom I will send them to
I will send them to Mary because it’s her birthday.
洋葱 Look, do you know what it is
Do you know how to plant onions
…
