人教版高中地理选修2中、低产田治理的地理背景教案
（1）黄淮海平原后备耕地不足，现有耕地面积不可能增加很多，因此提高农作物产量的着眼点应该是挖掘现有耕地的生产潜力。（2）黄淮海平原现有耕地中大部分存在着不同程度的限制性因素，对这些土地的整治是黄淮海平原发展农业，尤其是种植业的关键所在。[经典例题1]下列关于黄淮海平原的叙述，正确的是A、夏秋多雨，地势低平，易发生旱涝、盐碱B、从东向西，盐碱化程度越来越严重C、土地限制性因素面积占土地总比重最大的是干旱缺水土地D、黄淮海平原西部地区中、低产田分布较集中解析：黄淮海平原秋季降水少。从东向西，黄淮海平原地势渐高，盐碱化程度应渐轻。黄淮海平原西部地区，耕地质量较高，能够比较充分地满足农作物生长发育的需要，是黄淮海平原粮棉稳产高产区，故D选项是错误的。解答本题常见的错误是认为A选项是正确的，只要分析一下黄淮海平原秋季是否多雨就可以排除思维障碍：在正常年份，因受夏季风影响，7、8月锋面雨带控制黄淮海平原，带来大量的降水；秋季，锋面雨带对黄淮海平原影响较小，故降水也小。

关于独立国旗下讲话稿：独立个性对我们来说很重要
尊敬的老师，亲爱的同学们：大家上午好！我是来自xx班的。今天我国旗下讲话的题目是：独立个性对我们来说很重要。不知道大家对独立个性这个词语有怎么样的理解，我的第一反应是不依赖父母，自己的事情自己做。的确这是独立的基本大意，但独立个性好像不单单只是这样。对于一个具有独立个性的人来说，对自我价值的认可至关重要。每一个人都是一个独特的个体，每一个人的个性都有独特的一面。具有独立个性的人不仅是行动上的独立，更有思维上的独立；具有独立个性的人不会为自己的利益去做驾驭他人的事，不以自己的意志去束缚任何人，虽然以自我为中心，但却能尊重他人的意志和思想。拥有独立个性对自身来说也是终生受益。在我们的生活中，你是不是常常会发现有这样的同学。老师分享了一种学习方法，他就原样照搬，不顾自己的实际情况盲目实行，最后浪费了时间、精力，却收不到成效。

For example, the smart home could control the air conditioning and lights so that you would no longer have to turn switches on and off, and so that your home would be more energy-efficient. The smart home could also monitor itself to make sure that everything is working as it should, and send you warnings if there is a problem. Such smart homes could even be programmed to detect your health problems, and then give you reasonable advice as to the food you should eat or if you should see a doctor. So, in a sense, smart homes will lead us to living smarter lives.2.Create a smart function for your home, and share your creation in the next period.
