人教版高中政治必修4价值判断与价值选择精品教案
南极大地的水陆交接处，全是滑溜溜的冰层或者尖锐的冰棱。企鹅没有可以用来攀爬的前臂，也没有可以飞翔的翅膀，如何从水中上岸？纪录片《深蓝》展示，企鹅在将要上岸之时，要从海面潜入海中，沉潜到适当的深度，借用水的浮力，迅猛向上，飞出一道弧线，落于陆地之上。企鹅的沉潜是为了蓄势，看似笨拙，却富有成效。人生又何尝不是如此？沉潜绝非沉沦，而是勇敢、智慧、自强。如果我们在困难面前能沉下气来，不被“冰棱”吓倒，不被浮华迷惑，专心致志，自强不息，积聚力量，并抓住恰当的机会反弹向上，毫无疑问，我们就能成功登陆!反之，总是随波浮沉，或者怨天尤人，注定就会被命运的风浪所玩弄，直至精疲力竭。结合上述材料，运用《生活与哲学》知识对“价值观是人生的重要向导，有价值观的人生才是更美的人生”加以评析。7、有两名畜牧兽医专业毕业的大学生应聘到农村养猪场担任技术总监后，大力推广使用生态养猪法和中草药防疫技术，使养猪场步入了良性发展轨道。

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.
