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.

人教版高中地理选修3第五章第一节设计旅游活动教案
点拨：旅游地旅游资源的特色不同，可以安排的旅游活动是不一样的，直接影响对旅游者的吸引力。因此，出游前首先就需要收集旅游地旅游资源的类型、主要游览景区、景点的特色等情况。旅游地的时空可达性直接关系到旅游者从出发地到旅游地，然后再返回出发地的费用和时间。一般来说，居住地与旅游地之间的空间距离过大，会使旅行的时间过长、旅行费用过高，经济距离增加，相应地降低了旅游者的出游能力。而居住地与旅游地相距遥远，也意味着两地之间巨大的环境差异，这会增加对游客的吸引力。旅游服务设施和条件，如旅游交通方式及工具、旅游住宿条件、旅游餐饮的种类和标准、导游服务、旅行费用等信息也都在一定程度上影响着游客的选择。图5．3西藏布达拉宫和图5．4云南香格里拉两幅图片显示了西藏布达拉宫、云南香格里拉与众不同的优美景观，吸引了众多的游客前来观光旅游，成为近年来国内旅游的热点。
