人教版Book 7 Unit 3 Under the sea 教学设计〔教材解析〕本篇课文选自人教版新课标教材的选修模块7，为第一课时，阅读课,将Warming—up，Pre—reading，Reading, Comprehending部分放在同一课时教学，设计成为一节阅读课.故事发生于20世纪初期，一个名叫“Old Tom”的虎鲸帮助捕鲸人捕鲸以及营救遇难者的事情.通过对文章的整体认知和把握，教师给学生创设情境，让学生和自己的搭档自主地学习、思考和讨论，从而激发学生对动物的关注，鼓励学生去了解动物，爱护动物。

〔学情分析〕本课是高二年级下学期的课程，学生已经具备一定的知识储备和运用能力,但由于授课的对象的英语基础比较差，水平参差不齐，为了激发全部学生的好奇心和求知欲，课堂采用了创设情境，采用老师扮演鲸鱼,以猜谜的形式引导学生进入本节课。

通过对阅读的整体理解后，由学生扮演课文中出现的不同角色，，来活跃课堂气氛，引发学生对动物保护的意识。

同时，在阅读课中教师要渗透阅读的方法和答题的技巧,培养学生阅读的综合能力。

What evidence was there that Old Tom was helping the whalers out? Old Tom let the whalers know that there was a baleen whale nearby; he showed them the way to the whale work as a team. 2. What other animals did the author compare the killer whales with? Dogs. 3. “The killers started racing between our boat and the whale just like a pack of excit ed dogs.” why do you think the killer whales behave like this? Because they knew that, together with the whalers, they would soon kill the baleen whale and get a good feed. 4. Why did George think that the killer whales worked as a team? Because he could see that some of the killers were throwing themselves on top of the whale’s blow hole while others were preventing it from swimming out to sea. After the careful reading, they are asked to find the main idea and retell the story. First I will ask whether there are some volunteers, if not, I will ask certain students to talk about his main idea. Main idea: the killer whales can help whalers catch huge whales and even rescue whalers out in dangerous situations.
