人教版高中英语必修三学案：Unit2SectionⅡ

Unit 2 Healthy Eatiingi.教学内容分析本单元的中心话题是健康饮食。

主要是为了使学生对与健康有关的问题得到更好的理解。

这一单元鼓励学生去检查自己的饮食行为，看一看它是不是健康的饮食习惯。

一种健康的饮食习惯应该是平衡的，既不在脂肪、糖和盐这些方面过剩，又不会在人体必需的营养元素方面匮乏。

通过本单元的学习，学生可以对健康饮食有一个清楚的概念，从而根据所学的知识去思考与健康有关的问题。

Warming Up部分通过问题向学生询问饮食构成，让学生对本单元的內容能有一个初步的了解，并使学生复习与有关饮食的单词和短语。

然后让学生回答一组问题，通过这些问题的讨论，引导学生参与表达自己的看法，激发学生兴趣和好奇心，让学生自然而然地进入下一部分的学习。

Pre-wading部分通过几个问题讨论,让学生认识平衡营养的重要性，为课文的学习做出铺垫。

Reading部分主要讲述了王鹏和咏慧开饭店的故事，借此揭示了不同食物对人体有着不同的影响。

故事讲诉了王鹏和咏慧两家饭店的两种饮食都是不合理的，经常去王鹏的饭店容易发胖，这样会导致高血压和心脏病等疾病；而经常去咏慧的饭店的顾客则容易变瘦，这样容易导致厌食或是营养不良，让学生注意并避免走这两种极端。

这些距离学生自身生活很接近的问题很容易引起学生的思考。

在教授的过程中注意积极的引导学生不断的进行反思。

Comprehending第一部分通过True or False第四部分通过Main idea的寻找，使学生对文章有了一个浅层的理解。

Learning about Language部分突岀了词汇和语法的学习与训练。

本单元的语法是情态动词ought to等的基本用法。

Using Language部分中包括了听、说、读、写几个部分的内容。

学生可通过王鹏和咏慧的这一个事情，深入展开讨论与健康饮食有关的事情。

阅读后的习题及讨论不仅帮助学生加深对文章主旨大意的理解，更重要的是让学生学会用所学的知识，解决在现实生活中遇到的问题。

一、教学内容分析本单元的中心话题是“探索世界”，内容涉及人类如何超越极限、海上航行、郑和下西洋、人类攀登珠穆朗玛峰等，帮助学生了解人类在探索世界的过程中如何顽强地克服困难甚至超越极限。

语言技能和语言知识都是围绕这个主题设计的。

“热身”(Warming up)部分由四幅图片和四个问题组成。

要讨论这四个问题学生必须了解郑和、克里斯托弗·哥伦布、詹姆斯·库克和艾贝尔·塔斯曼这四个人物的事迹，他们都为“人类探索世界”做出过巨大的贡献。

在了解人物主要事迹的基础上，学生可以总结出四位人物的共同特点：他们都是探索世界的航海家，从而回答第一个问题。

对于高三的学生来说，回答第二个问题应该很容易，可以复习七大洲的名字。

对于第三、四个问题，学生在讨论的基础上也可以提供部分的答案。

这两个问题的讨论有助于接下来做听力练习。

“听力”部分是一个记者和一个教授之间关于人类过去和现在探索未知世界所可能遇到的困难与挑战的对话。

在听之前让学生讨论练习1的三个问题有助于学生对对话内容的预测，熟悉对话中出现的词汇和表达方法，从而降低听的难度。

练习2让学生比较过去和现在在交际和交通上的重要差异，可以让学生了解过去探索世界的巨大困难。

在录音内容中可以直接得到有关这两方面的情况。

练习3中所设计的几个问题也是围绕人类过去和现在探索未知世界所可能遇到的困难与挑战的主题所设计的，主要训练学生把握文段细节的能力。

“口语”(Speaking)部分要求学生对形势作出分析判断，然后提出相应的对策和作出决定。

在这一部分，学生阅读相关材料并提出他们自己的观点。

在这一过程中学生可以了解我们该如何探索世界，以及如何对待我们探索世界时候所发现的地方、空间、文物等，对于培养他们探索未知世界的热情和克服困难的决心有促进作用。

“读前”(Pre-reading)部分的第一个问题让学生了解“丝绸之路”的有关情况，为第二个问题做好铺垫，那就是在中国陆路已经和其他洲建立联系的情况下，为何还要开辟更长的水路联系?这有何重要意义?从而为我国历史上的那些航海家探索“海上丝绸之路”找到依据。

At the beginning of the class, the teacher can lead in the topic of the unit by showing students some pictures about foods and talking about them.Warming Up is to tell students how different kinds of food are grouped. This is important as it enables us to talk about the value of particular foods to our health. We want students to appreciate what a balanced diet is. T oo much fatty food will mean they store extra energy in their bodies. Too much body-building food may cause problems for digestion and lead to illness unless enough fibre foods are eaten to aid digestion. The teacher can have a free talk with students, let them work in pairs to read through the chart and discuss the questions.Pre-reading contains two more general questions about food for discussion. Students can be encouraged to discuss these questions in pairs. Then they are asked to look at the title of the reading passage and the pictures to predict what the passage isabout. This part is very useful for the next part Reading.The reading passage Come and Eat Here(1)introduces students to two unbalanced diets through the restaurants of Wang Peng and Yong Hui. Food at Wang Peng’s restaurant contains too much fat while Yong Hui’s restaurant offers little energy-giving food. The person who often eats at Wang Peng’s restaurant will become too fat. That can lead to illnesses such as a heart attack or high blood pressure. The person who often eats at Yong Hui’s restaurant will become too thin and suffer illnesses such as anorexia or malnutrition. It is important for students to know about the two extremes and avoid them. The teacher can encourage students to skim for the general idea and scan for further understanding. Because this passage introduces a lot of new words, which are only used for food, in order not to let students feel much difficult, the teacher should deal with any language problems while they are reading. After reading, students are required to do the exercises in Comprehending to see how much they have understood the reading passage. The teacher can let them work in pairs or in groups to find the answers cooperatively, and then checktheir answers with the whole class.To consolidate the contents of the reading passage, students should be required to read the passage again and then retell it. In order to arouse their interest, the teacher can hold a competition. The teacher also needs to make a summary on the passage including the general idea, writing characteristics, and so on to let students understand the passage further at the end of the class.教学重点1.
