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

人教版高中地理选修1月球和地月系教案
月球对地球的意义月球与地球形影相随，关系密切。月球对地球的影响，主要有以下几方面：1．地球上夜晚的自然照明，主要靠月亮。2．远在古代，人们就根据月相变化的周期，编订历法。我国农历月份的安排，是以月相变化 周期为标准的。农历规定朔为初一，这样，望就在十五日或十六日。我国人民的传统节日，像春节、中秋节就是按农历的月日计算安排的。3．由于地球表面各处所受月球和太阳引力的不同，地球上的水体产生了明显的潮汐现象。4．月球是人类星际航行的第一站。已知月球表面有多种宝贵矿藏；重力较小；没有大气层，利用太阳能的条件较好。如何利用月球的特殊环境，开发月球的资源，以及如 何利用月球作“码头”，使人类更好地研究宇宙，这将是月地关系的新篇章。

5.对土星五号火箭和登月舱的质疑现代航天飞机只能把20吨载荷送上低轨，而当 年的土星五号却能轻而易举地把100吨以上载荷送上地球轨道，将几十吨物体推出地球重力圈，为什么后来却弃而不用，据说连图纸都没有保存下来？6.温度对摄影器材的影响月面白天可达到121°C，据图片看，相机是露在宇航服外而没有采用保温措施的。胶卷在66°C就会受热卷曲失效，怎么拍得了照片？这些人士认为，对以上这一切美国政府一直没个 交代，而知情者由于担心生活和安全受到影响，甚至可能直接遭到了胁迫，至今对此沉默不言。但相信不久的将来，诞生于美苏太空竞赛年代的“登月骗局”定会水落石出。反驳不过，也有许多人认为“阿波罗”登月计划不可能造假：首先因为该计划当时是在全球实况转播的，近亿人亲眼看到。另外，宇航员还从月球带回了一些实物，如岩石。

The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences.

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:? Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better?? Bill: Much better, thanks. But how was it?? Judy: Wonderful! I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool.
