    新人教版高中英语必修3Unit 4 Space Exploration-Reading for Writing教学设计二

    ⑦在我看来, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand,70% think space is worth exploring because we have benefited a lot from it,such as using satellites for communication and weather forecast. What’s more,with further space research,we may solve the population problem by moving to other planets one day. Also,space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner. Use this checklist to help your partner revise his/her draft.1.Does the writer explain why he/she changed/wanted to change?2.Does the writer tell how the changes have improved or will improve his/her life?3.Is the text well-organised?4.Does the writer use words and expressions to show similarities and differences?5.Are there any grammar or spelling errors?6.Does the writer use correct punctuation?

    新人教版高中英语必修3Unit 5 The Value of Money-Reading and Thinking教学设计一

    Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

    人教版高中地理必修1自然地理环境的整体性教案

    1.生产功能:合成有机物的能力2.平衡功能:使自然地理要素的性质保持稳定的能力【教师讲解】生产功能主要依赖于光合作用。在光合作用过程中,植物提供叶绿素,大气提供热量和二氧化碳,土壤及水圈、岩石圈提供水分及无机盐。光合作用通过物质和能量的交换,将生物、大气、水、土壤、岩石等地理要素统一在一起,在一定的条件下,生产出有机物。由此可见,生产功能是自然环境的整体功能而非单个地理要素的功能。大气本身不具有减缓二氧化碳增加的功能,但是,在自然地理环境中,通过各地理要素的相互作用,却能消除部分新增的二氧化碳的能力,既为自然地理环境的平衡功能。请大家阅读教材P94活动,利用平衡功能的原理,解释一定范围内各物种的数量基本恒定这一现象。【学生讨论回答】略。(可参考教参)【转折】自然地理环境各要素每时每刻都在演化,如我们熟知的气候变化、地貌变化等。各个要素的发展演化是统一的,一个要素的演化伴随着其他各个要素的演化。
