人教版高中生物必修2基因是有遗传效应的DNA片段说课稿
1.基因的化学组成：每个基因含有成百上千个脱氧核苷酸。讲述：基因的脱氧核苷酸排列顺序代表遗传信息。2.基因不同的实质：不同的基因，四种脱氧核苷酸的排列顺序不同，但是每个基因都有特定的排列顺序。3.基因的位置：染色体是基因的主要载体，每个染色体含有一个DNA分子，每个DNA分子含有多个基因，基因在染色体上呈直线排列。4.基因是有遗传效应的DNA片段这就是说，基因是DNA的片段，但必须具有遗传效应（指具有复制、转录、翻译、重组突变及调控等功能）。有的DNA片段属间隔区段，没有控制性状的作用，这样的DNA片段就不是基因。控制某种性状的基因有特定的DNA片段，蕴含特定的遗传信息，可以切除，可以拼接到其他生物的DNA上，从而获得某种性状的表达。例如：把牛的胰岛素基因拼接到大肠杆菌的DNA上，大肠杆菌可以生产胰岛素。

人教版高中语文必修1《优美的汉字》说课稿
明确：（1）结绳记事说。原始记事的一种方法。人类在没有发明文字或文字使用尚不普遍时，常用在绳索或类似物件上打结的方法记录数字，表达某种意思，用以传达信息，处理事件。 （2）书画说。（3）仓颉造字说。中国自古就有仓颉造字之说。文字的发明是人类发展史上一件石破天惊的大事，它将人们的思维、语言、经验以及复杂的社会现象记录下来，使文化得以传播交流、世代传承。2、汉字的形体：中华民族五千年的历史中，汉字的演变，从甲骨文－－金文－－大篆－－小篆－－隶书－－草书－－楷书－－行书，字形由象形到点横竖撇捺的方块字，经历了漫长的岁月。其中凝聚着民族的智慧，也体现出汉字逐步完善的过程，凸显其方方正正、四平八稳的特点。汉字又是一种文化的体现，那些经过艺术处理的汉字或跳起了拉丁舞、有的如同酒醉的成龙打起了醉拳，更是让我们感到的是在欣赏汉字在纸张上跳舞，所以：书法是“纸上的舞蹈”。请大家看到书上的相关内容，注意每一种形体的汉字的载体是什么，其功能又有什么不一样。
人教版高中语文必修2《故都的秋》说课稿3篇
请一位朗诵水平较好的学生，有感情的朗读课文12自然段，其他同学完成一项任务：这一段可否去掉？为什么？学生思考、圈画、交流、讨论，然后小组发言，其他小组补充，教师从旁予以点拨，引导学生进一步明确作者的思想情感。明确：作者要创造一种文化氛围，于自然气息之外再添一重文化气息，与“故都”题旨暗合。从行文章法上看，这里是宕开文笔，纵横议论，显出深厚的文化底蕴和开阔的思路。这一段采用议论，通过古今中外的引证，说明感秋处处有，中国文人最突出，而秋“深味”非在中国北方莫属，这其实还是为了突出故都之秋。（设计意图：提高学生探究的能力，充分把握本文的教学内容，深刻体悟作者的情感，了解作者对秋的礼赞情感，从而突破教学难点。）
人教版高中语文必修3《宇宙的边疆》说课稿2篇
（有的恒星旋转平稳均衡，有些恒星是因快速旋转而变了形。作者以拟人的手法，生动形象地描述，仿佛向我们展示了不同恒星的性情：有的稳重沉静，有的急切躁动。读来生动有趣，妙趣横生。）(3)我们探索宇宙的时候，既要勇于怀疑，又要富于想象。想象经常能够把我们带领到崭新的世界，没有想象，我们就处处碰壁。怀疑可以使我们摆脱幻想，还可以检验我们的推测。（对于未知领域的探索是需要怀疑和想象的，想象是科学的翅膀，敢于想象，并不断地探索验证，所谓“大胆假设，小心求证”怀疑否定旧知，产生新知。作者以简洁的语言阐述了想象和怀疑看似矛盾的两者在宇宙探索中的相辅相成，和谐统一。作者不囿于介绍宇宙知识，还发表自己的见解。）(4)我认为宇宙里很可能到处都充满着生命，只是我们人类尚未发现而已。我们的探索才刚刚开始。
丰富的图形世界 展开与折叠教案教学设计
设计意图：题目1是判断能否折叠形成立体几何，本题可以研究学生对常见几何体的把握是否成熟。题目2是考察正方体的展开图，一方面可以研究学生对几何体的把握，另一方面可以引导学生思考，引出下面要学习的内容。）学生预设回答：题目一：学生应该很容易的说出折叠后形成的立体图形。题目二：①运用动手操作的方法，剪出题目中的图形，折叠后对题目做出判断。 ②利用空间观念，复原展开图，发现6的对面是1，2的对面是4，5的对面是3，进而做出判断。教师引导语预设：① 当学生运用动手操作的方法，可以让学生动手实践一下，下一步再引导学生观察正方体，发现规律。② 当学生运用空间观念，教师要放慢语调，和学生一起想象，锻炼学生空间想象能力。
人教版高中历史必修2古代的经济政策说课稿
3、清代的“闭关锁国”政策：（1）原因：①根本原因：自给自足的封建自然经济；②客观原因：西方殖民者向东方殖民扩张；③直接原因：对付东南沿海人民的抗清斗争（2）内容：严格限制对外贸易。但并不是禁绝海外贸易。康熙晚期，禁止商人前往南洋贸易；乾隆时只开广州一处通商，并设立政府特许的贸易机构广州“十三行”统一经营管理对外贸易。（3）后果：①闭关锁国政策妨碍了海外市场的开拓，抑制了资本的原始积累，从而阻碍了资本主义萌芽的发展。②闭关锁国政策隔绝了中国与外界的联系，从而阻断了中国学习西方的先进科学技术，阻碍了生产力发展，使中国落后于世界潮流。③“闭关锁国”政策在一定程度上也保护了国家的安全。教师可以设置问题：17-18世纪中国显露出哪些危机？
人教版高中语文必修1《记梁任公先生的一次演讲》说课稿2篇
6、思考：作者心目中的梁启超是什么形象呢？明确：梁任公是位有学问，有文采，有热心肠的学者。由学生找出文中体现梁启超学问、文采的句子。教师展示幻灯。补充介绍：文采不仅体现在书面，也能从流畅的口语表达中反映。《箜篌引》短短十六字蕴涵了什么故事，竟让梁启超描述得生动感人以至作者多年后还印象深刻呢？《箜篌引》出自《汉乐府诗》，记叙了一个悲惨壮烈的故事：朝鲜水兵在水边撑船巡逻时，见一个白发狂夫提壶渡江，被水冲走。他的妻子劝阻不及，悲痛欲绝，取出箜篌对着江水反复吟唱。一曲终了，她也投河随夫而去。朝鲜水兵回家向自己的妻子丽玉讲述了这个故事，丽玉援引故事中的悲情，创作了这首歌曲，听过的人无不动容。7、朗读训练了解《箜篌引》的故事后，请各小组选派代表朗读，由学生点评，体会梁启超演讲技巧的高超。8、文中说梁任公是个热心肠的人，你同意吗？通过结尾段的“热心肠”转入对其人格的分析。
人教版高中生物必修3第一章第二节《内环境稳态的重要性》说课稿
四、稳态的重要意义 为什么内环境稳态失调后，会对机体造成危害？引导学生从细胞代谢需要的物质和条件进行分析，最后总结出：内环境稳态是机体进行正常生命活动的必要条件。如何预防内环境稳态失调、保持机体健康？引导学生从外界环境和机体自身调节能力两个方面去思考。即通过加强自我保健，减少外界环境变化对机体的不良影响，同时增强机体的调节能力以适应多变的外界环境。具体如何做？学生讨论，总结。1.保护我们的生存环境，防治环境污染。2.加强体育锻炼，增强体质，提高机体适应外界环境的能力。3.加强自我保健，为机体保持健康创造有利条件。尤其是处于比较恶劣的工作环境中的人，更应注意自身保健，如边防战士注意保暖、炼钢工人注意降温、抗洪战士注意补充水盐等。了解这些知识后才能懂得如何关爱自身和他人。

人教版高中地理必修1第三章第一节自然界的水循环说课稿
二、说学情学生对自然界中的水循环已具有一定的生活体验和知识基础，主要问题是学生还未上升到理性的层面上进行分析，而且自然界的水循环属于全球尺度和大尺度的地理现象，学生难以理解，需要教师创设适当的情境引导学生进行新知的建构。三、说教法（1）创设情景：教学实践证明，合理有趣的情境创设，可以引导学生快速进入角色，提高课堂效率（2）讨论法：通过组织学生讨论，给学生提供自主学习、合作学习、探究学习的机会。（3）多媒体演示法：利用多媒体播放一些直观的图片、动画和数字资料，把学生轻松得引入本课，通过形象生动直观地展现相关地理事物和现象，提高学生的感性认识，激发兴奋点，帮助他们理解课本内容。四、说学法（1）学会用图：让学生仔细观察图3.2和图3.3理解水循环的相关性（2）学会探究：学生思考分析总结水循环的地理意义及黄河断流的原因。

人教版高中英语必修4A taste of English Humor说课稿3篇
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill
