人教版高中政治必修4综合探究：坚定理想，铸就辉煌教案
理想扎根在实践的土壤中理想当然是重要的，但是不能把理想当成幻想或空想，理想必须扎根在实践的土壤中。青年人充满激情，这是非常重要的。古人有句话：“哀莫大于心死”。最大的悲哀就是没有追求，就像一团火焰熄灭了一样，即使到了我这个年纪也不能“哀莫大于心死”。青年人都有很高的激情，这是很好的。但是青年的激情往往不大稳定，过去人们说青年人的热情是“三分钟的热度”。这句话不一定准确，但青年人在这一点上应该有一个正确的认识。记得我大学毕业时，对于走向社会、走向生活充满了幻想，认为生活中的一切都是美好的，是典型的理想主义者，因此，对自己不能正确的估价，好高骛远，只愿做大事，不愿也不注意从小事积累。列宁说过，大事是由小事积累而成的。我当初毕业时，一方面充满了激情，另一方面也确实过高地估计了自己。

7．我国人力资源开发利用面临四大挑战在全面建设小康社会进程中，我国人力资源开发与利用面临着以下四个方面严峻挑战。(1)劳动力供给高峰的到来加剧了劳动力供求总量矛盾。持续的经济增长和人口计划生育控制，使得我国人口再生产在不到30年的时间内完成了从“高出生率、低死亡率、高自然增长率”的类型到“低出生率、低死亡率、低自然增长率”类型的转变，人口在日增长率已经连续数年低于千分之十。然而，庞大的人口基数及其低速增长仍对中国未来经济增长和社会发展带来巨大的就业压力，大量预测表明，未来20年是中国人口数量增长和劳动力供给的高峰时期。20世纪90年代以来，中国劳动年龄人口比重(16—59岁年龄组)由1990—1996年期间的61％～62％上升到1999年的63．2％。这种趋势将会持续到2020年左右达到峰值，直到老龄化进程抵消了数量增长效应，劳动年龄人口的比重才会趋于下降。到2020年，中国劳动年龄人口将由2000年的8．61亿上升到10．04亿，平均每年新增劳动力715万人。

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。

He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city.
