人教版高中地理选修1第二章第一节太阳和太阳系教案
教学过程【导入新课】在太阳系中，九大行星就好像一个家庭中的九个兄弟，有许多共性，今天，我们就一起来了解九大行星在运动特征和结构特征上的共同之处。【板书】3．九大行星的运动特征和结构特征【启发引导】请同学们一起阅读地图册上的“太阳系模式图”，读图分析：（1）九大行星在公转的方向、轨道等方面有什么共性？（2）图中符号“i”、“e”代表什么意思？这两组数字能说明什么问题？九大行星公转的方向相同，均为自西向东转，我们称为同向性。符号“i”表示轨道倾角。（简介黄道、黄道面、轨道倾角）各大 行星的轨道倾角都很小，只有水星和冥王星的大一些，最大也不过17°，说明九大行星的公转轨道近似在同一个平面上，我们称之为共面性。符号“e”代表公转轨道椭圆的偏心率，即焦点到椭圆中心的距离与椭圆半长轴之比，它决定椭圆的形状。偏心率越小，越趋向于圆，当偏心率为0时，轨道就是圆。

新人教版高中英语必修3Unit 4 Space Exploration-Listening&Speaking＆Talking教学设计二
The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3.

⑦在我看来, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

人教版高中地理必修1第二章第四节全球气候变化教案
气候变化对健康的影响 气候变化对人体健康的不良影响是不难发现的：热浪冲击频繁加重可致死亡率及某些疾病、特别是心脏呼吸系统疾病发病率增加；对气候变化敏感的传染性疾病如疟疾和登革热的传播范围可能增加。极端气候事件, 如干旱、水灾、暴风雨等, 使死亡率、伤残率及传染病疾病率上升, 并增加社会心理压力。某些媒介疾病的加重也可能与气候变化有间接的关系, 如疟疾是通过蚊子传播的疾病,气候变化可能使某些变暖地区的蚊子数目增加, 从而加重了疟疾的发生。我国1994年疟疾的发病率为5.3408/10万, 居全国法定传染病的第六位。血吸虫病的发展与高温及灌溉系统的扩增有关。我国1994年南方12省市血吸虫病患者的检出率高达3.67%，不能忽视气候变化对此的可能影响。还有一些疾病，如睡眠病、登革热、黑热病等也有与气候关系的报道。另外, CO2、一些空气污染物如氮氧化物、臭氧等可增加过敏疾患及心脏呼吸系统疾病和死亡。
人教版高中地理必修3第五章第二节产业转移教案
1．阅读图5．16，说明产业向国外转移对日本经济的不利影响。点拨：图5．16直观的显示了产业转移对日本经济的不利影响：形成“产业转移出去的多，转移进来的少→国内生产投资不足，生产困难→市场萎缩→产业向外转移，外资不愿进入”的恶性循环。2．尽管重化工业的环境污染比较严重，但是却能为工业化的发展提供坚实的基础，因此成为发达工业的象征。日本、韩国的经济发展都经历了由轻工业(劳动密集型)到重化工业(资源密集型和资金密集型)到高科技工业(技术密集型)的阶段。(1）为什么日本、韩国在重点发展重化工业之前，要先发展劳动密集型工业?点拨：重化工业的发展一方面需要有一定的工业基础和技术工人，另一方面需要投入大量的资金，先发展劳动密集型工业有利于利用劳动力资源丰富且廉价的优势，积累资金和造就产业工人。所以，劳动力丰富的发展中国家或地区的工业化往往从优先发展劳动密集型工业开始。

部编版小学语文四年级下册第25课《两个铁球同时着地》优秀教案范文
1、齐读第三自然段。思考：亚里士多德讲过什么话?伽利略对这话是怎么看的?（亚里士多德说过：“两个铁球，一个10磅重，一个1磅重，同时从高处落下来，10磅重的一定先着地，速度是1磅重的10倍。”伽利略对这话产生了怀疑）2、伽利略为什么怀疑亚里士多德说的话?他是怎么想的?（“他想：如果这句话是正确的，……这怎么解释呢?”）3、伽利略的分析，是把亚里士多德的话当作两种假设，推出两个结论。这两个结论是什么?（①把一个10磅重，一个1磅重的两个铁球拴在一起，如果仍然看作是两个球，落下的速度应当比原来10磅重的铁球慢。②如果看做是一个整体，落下的速度，应当比原来10磅重的铁球快）4.这两个结果一样吗?是什么样的结果?（不—样，是相互矛盾的）5.根据同一句话，会推出两个相互矛盾的结果，所以伽利略认为这句话是靠不住的，值得怀疑。6，他打算怎么做?（用试验来证明不同重量铁球落地的情况）

国旗下的讲话：铭记一二·九（学生演讲稿）
国旗下的讲话：铭记一二·九 各位老师、同学们：早上好！今天是一二。九运动的纪念日，这个青年学生的爱国运动距今已有73周年了。今天，站在鲜艳的国旗下，让我们一同回顾历史：谁都应该记得1935年的12月9日，谁都不应该忘记“一二。九”这场轰轰烈烈的学生爱国救亡运动。虽然，它早已成为历史，但它的事迹，它的精神，却早已铭刻进了我们每一位炎黄子孙的心中。他们用自己的青春和热血掀起了全国抗日救亡运动新的高潮。今天，我们在这里缅怀一二。九先辈的功绩，心潮澎湃，不能自己。作为新时代的青少年，同学们，我们又应该做些什么？抗战时期的大中学学生，他们把自己的生命和国家的命运、民族的兴亡，紧紧的联系在了一起。而我们，是否也应该象他们一样呢？答案当然是肯定的，但现实又如何呢？台下的有一部分同学，当你在课堂上无精打采的听课时，当你将青春耗费在虚拟的网络时空时，当你沉溺于追逐流行和崇拜明星时，当你盲目的“耍酷”“装帅”，张扬你所谓的“个性”时，不知你是否想到了作为当代青少年那肩头沉重的使命感？
高二学生国旗下讲话稿：天下兴亡，我的责任
敬爱的老师们，亲爱的同学们：大家早上好！我先给大家讲一个故事：1920年，有一位11岁的美国男孩在踢足球时不小心踢碎了邻居家的玻璃，邻居愤怒不已，向他索赔12.5美元。这12.5美元在当时可谓是天文数字，足够买下125只生蛋的母鸡了。男孩把闯祸的事情告诉父亲，并且忏悔。见儿子为难的样子，父亲拿出了12.5美元说：“这笔钱是我借给你的，一年后你要分毫不差地还给我。”从此，这个男孩每逢周末、假日，便外出辛勤打工。经过半年的努力，他终于挣足了12.5美元，分毫不差地还给了父亲。这个男孩就是后来的美国总统里根。他在回忆这件事时说：“通过自己的劳动来承担过失，使我懂得了什么叫责任。”责任，这两个字很好读，一点也不拗口，但这是个沉甸甸的话题。责任是什么？用歌德的话来讲，就是对自己要求去做的事情有一种爱。这是一个真实的故事。有一个人来他公司应聘，经过交谈，他觉得那个人不适合他们公司的工作。因此，他很客气地和那个人道别。那个人从椅子上站起来时，手指不小心被椅子跳出来的钉子划了一下。那人顺手拿起老板桌子上的镇纸，把跳出来的钉子砸了进去，然后和老板再见。
