一、培养问题意识、促进心智发展
问题意识能促进学生积极主动地开展学习，能激发学生的求知兴趣和欲望。本节课我以问题贯穿整个教学过程。在设计问题时既要在一定程度上与学生已有的知识或技能有联系,也渗透一些学生原来尚未掌握的新知识,这样既能使学生有所获，也能激发学生的求知欲望和积极性，并且还可引发学生生成更多、更有深度和创意的新问题，使学生善学、乐学、好学。此外，本课也有意识地引导学生有效使用学习策略，如课上指导学生总结文中出现的城市的共同点、体会文章所传递的文化内涵等，提升学生的学习力。
Look at the pictures about different places of interest and guess which cities they are in.
与学生已有的知识，自己的生活经验建立联系，激活学生的背景知识。

Then have them discusstheir ideas with partners. Encourage them to say why or why not they'd like to take the journey. Monitor, offering help as needed.➢Discuss their answers as a group. Encourage students to share their ideas.SpeakingExercise 7Purpose: to help students give presentations about the journey to the South Pole➢Say Imagine you were on that expedition to the South Pole. After the journey is over, how do you feel?”Elicit words from students (negativeand positive) , such as wonderful，tired, excited, sad, proud ...➢Tell them that as members of the expedition, they have been invited to put together a presentation about their journey to students at a school.Ask What are you going to talk about?”Elicit ideas.➢Then ask students to think about the three main topics that the writer covered in his report about the journey to the South Pole. In groups of four, have them note three main topics (referring them to the report form in Exercise 5, if needed). After discussion, note these three main topics on the board;(1) people on expedition(2) difficulties faced on journey(3) lesson (s) learned➢In groups of four, have students prepare their presentations. In order for your students to feel more confident, set clear guidelines. Here are some tips:⭕Encourage students to provide focus to their presentations by identifying the three main topics and making notes about each ( based on the information from the text in Exercise 3). They can take examples from the text about the people involved and the difficulties they had, and then provide more details to make their presentations more interesting and personal. ( They want their listeners to get a clear idea how they feel about the expedition. ) Finally, they can conclude their presentations by talkingabout what they learned from the expedition. Again, encourage them to provide their personal thoughts here.⭕Don't make the presentations very long. Clearly provide information about the three topics:(1) Who was on the team?(2) What difficulties did you have?(3) What did you learn from the expedition?Note: Write these questions on the board alongside the three topics noted earlier.⭕Make sure students know that they should make notes and not write the entire presentation down. This is meant to be a speaking exercise, not simply reading aloud one's notes. Have them look at the report in Exercise 5 for an example of how to present notes.⭕Assign roles for the presentation. Suggest;•Student A presents the opening statement and discusses who was on the team.•Students B and C share responsibility for discussing the different difficulties.•Student D discusses the lesson (s) learned and provides the closing statement.⭕Tell students to practise! This will help them use clear language and organise their thoughts well.⭕Encourage them to use expression in their voices. They are telling about an exciting expedition.⭕Try to think about their audience when planning or presenting their talk. What might be interesting and helpful for the audience to hear?➢Go over relevant points from the list above.Have students work over these points in class and then assign the preparation and practice of the presentation for homework. If time allows, give some time to practise in class as well.➢Leave time for students to ask questions and or ment after each presentation.Expansion: Do Some Research!Note: For more proficient students, have them research the expedition of either Robert Falcon Scott or Roald Amundsen. Have them answer these questions:Who was this person? Where was he from?When did he begin his journey to Antarctica?What happened on his journey?➢If time allows, do Workbook pages 158 and 159 in class. Alternatively, assign for homework.。

4.任务驱动：教师布置与环境保护相关的任务，如调查报告、海报设计等，让学生在实践中运用所学知识。
5.反思评价：教师引导学生对学习过程进行反思，总结学习方法和经验，提高自主学习能力。
（三）情感态度与价值观

5.阅读与写作：学生能够阅读并理解与环境保护相关的文章，学会提取关键信息，提高阅读速度。同时，能够运用所学知识，撰写关于环境保护的短文。
（二）过程与方法

构造以 上弦、中切、下割；左正、右余、中间
就 的正六边形为模型。
1 、倒数关系
对角线上两个函数互为倒数；
2 、商数关系
六边形任意一顶点上的函数值等于与它相邻的两个顶点上函数值的乘积。
sin( α - β )=sin α cos β -cos α sin β
我们把两式相加就得到
sin( α + β )+sin( α - β )=2sin α cos β
所以 ,sin α cos β = sin （α ? β ）? sin （ α — β ）
2
同理 , 若把两式相减 ,就得到 cos α sin β = sin （α ? β ）— sin （α — β ） 2

tan （ 3π －α） = cotα
