一. 教材分析
本篇课文The language of honey bees 是新编英语教材第三册的第14单元，是一篇科技性说明文。讲述了一位科学家对蜜蜂交流食物信息途径的研究。涉及到蜜蜂如何通过舞蹈传递食物的远近和距离等内容。就本单元Zoology而言，reading部分是本单元的中心，一方面有warming- up 和 speaking 当中学到的有关动物的知识为其作铺垫，另一方面此课的学习又为下面的Primates 打下基础，使学生能在reading 中学到的关于动物的信息和探索的科学方法，以及阅读中获得的阅读技巧得到更好的应用和发挥。就本册教材而言前四个单元都是有关对自身极限和对自然界的探索，在第十单元又涉及到了成功的关键，这就为本课的学习奠定了情感基础。另一方面，这是第十三单元的课文，已接近本册书的结尾，所以在语言能力的各个方面学生也都有了一定的积累。因此，从内容上看，本节课是对前面所学单元主题的再现与升华。本课的学习可以进一步培养学生的探索能力，推理能力和空间的想象力。．
二．学生情况
相对而言，理科班的学生英语要弱一些，而本篇文章的很多句子和段落的语言不够清晰明了，对他们来说是有一定的难度的。但由于本文涉及到了蜜蜂的舞蹈，是属于动物学的问题，从内容上看应该是理科班的学生更感兴趣的话题。
为了使学生更好地理解本篇文章，达到教学目的，就必须通过将抽象的语言用图片或动画表现出来以减小语言上给他们带来的压力，同时又要激发他们原有的对动物的兴趣。

Ⅱ. Presentation
Step 1: fast reading and do T or F
All bees do not live in trees.
Honey-bees interested scientists most.
Bees communicate the news of food to other bees outside their hive.
There are three dances mentioned in the text.
The number of wagging dances per minutes told the direction to the feeding place.
Step 2: careful reading
Task 1: reading the text and match the main idea with the right paragraph.
Task 2: find out the ways bees used to communicate information of food
Answer some questions
Para2-3 1.What the scientist assume first?
2. What did they do for their assumption? Was it proved?
3.What kind of a dance was found?( flash)
4. What was the conclusion?
Para 4-5 5. What was the other dance?(flash)
6.What information did it convey?
7.What’s the difference between the two dances ?
A circle dance Food is near.
