4月份国旗下讲话：说说爱国卫生月
尊敬的老师，亲爱的同学们：今天国旗下讲话的题目是：“说说爱国卫生月”。同学们，四月是个春暖花开的季节，可你还知道四月是个什么月吗?告诉你吧，四月是全国爱国卫生月。因为卫生工作关系到每一个人，所以请大家在日常工作、学习、生活中积极主动做好卫生工作，保持良好的正确的卫生习惯，促进健康成长。1、保持良好的个人卫生习惯，注意饮食卫生，不能在路边小摊随便购买食品，因为路边摊卫生根本就不能得到保证，各种尘埃、苍蝇、不干净的食品用具等都隐藏着多少有害细菌，但是我们有时也发现有的同学在放学后就喜欢在这些路边小摊驻足购买食品，这是非常不卫生的。在个人卫生习惯中，养成饭前便后要洗手，勤剪指甲，勤洗澡，不随便使用别人的生活用品，如毛巾、衣服、拖鞋、餐具等。遵守作息时间，做到起居有规律。2、均衡饮食，随气候变化而增减衣服，定期运动，充足休息。在日常生活中同学们应该按照生活规律，定时用膳，三餐饭做到定量，不能饿一餐，饱一餐，特别是早晨，我们有的同学就往往因为睡懒觉而未吃早餐，这对身体健康和学习精力都是不利的。同学们早晨起床后到户外锻炼，呼吸一些新鲜的空气，伸伸腰，踢踢腿，跑跑步都是很有好处的。

人教版高中政治选修3美国的联邦制教案
3、联邦制的弊端：（1）、效率不高：（2）、集团分享权力，维护资产阶级的利益，不顾人民要求。在美国实行联邦制的二百多年问，联邦制的弊端也显露无遗。美国联邦制的最大问题是效率不高，联邦政府与州政府之间相互扯皮、推诿，各州政府之间各自为政。全国性资产阶级利益集团与地方性资产阶级利益集团分享权力，对于广大人民群众的要求，资产阶级则利用国家结构形式的特点相互推卸责任。当大多数资产阶级利益集团意见接近时，联邦制既能保护州的灵活性，又能保证中央的权威；当资产阶级利益集团之间矛盾重重时，联邦制就处于低效运转之中。相关链接：1954年，美国最高法院在一项判决中宣布，公立学校实行种族隔离、拒绝黑人入学是违反宪法的。这一裁决引起南方一些州的抵制，一些州竟以暴力阻止黑人进入公立学校。

人教版高中政治选修3美国的利益集团教案
（3）、各种利益集团内部很少有什么民主机制，大都为少数人所控制——从利益集团内部的管理机制看；广大群众常常对某些组织寄予期望，投人力量，但是他们的利益却往往得不到关注。（4）、利益集团为政府腐败提供了肥沃的土壤。利益集团的活动方式，在很大程度上是用金钱购买政治影响力，是一种滋养腐败的行为——从利益集团对政府的负面影响看。实际上，在国会议员、政府官员与利益集团之间，已经形成一种相互依赖的共生关系。3、利益集团机制的隐蔽性、欺骗性及其实质：美国政坛中的利益集团机制，是资产阶级控制国家机器的一种特殊形式，具有相当强的隐蔽性和欺骗性。表面上看，利益集团是所谓的“民意代表”，向政府反映各阶层、群体的观点和利益，实质上是资产阶级在“民意”的幌子下控制权力。
人教版高中政治选修3美国的三权分立教案
国会一直在政治生活中居于主导地位；到了当代，则是总统居于主导地位。由于司法机关无权直接支配社会力量和财富，相比之下，联邦法院力量向来较弱。第二次世界大战后，由于美国一直追逐全球霸权，美国总统的战争权力更加强化，向海外派遣军队的次数更加频繁。美国人民日益觉察到这种不断增长的“帝王般总统职位”可能带来的危险。2、三权分立制的本质——是一种资产阶级民主制度美国的三权分立制本质上是一种资产阶级民主制度。二百多年的历史经验表明，它有效地维护了美国资产阶级的统治。但是，广大劳动人民不可能在这种制度下享有真正的民主。虽然三大权力机关之间互相制约、平衡，却没有一个代表人民意志的权力机关，因而不可能实现人民群众的多数人统治。◇本框题小结：◇3个3种权力：3种权力即立法权、行政权和司法权；3个弊端：即三权分立原则的3 个弊端；3个中央政权机构即立法机关、行政机关和司法机关；◇2个原因：即确立三权分立原则的原因◇1个本质：即三权分立原则的本质
