作者为什么要这样详细地介绍恐龙的“庞大家族”?说明恐龙飞向蓝天的演化过程。在复述文章内容的时候,思维导图会有很大的帮助。请用思维导图的形式,简要概述恐龙飞向蓝天,演化成鸟类的过程。恐龙第一种恐龙两亿四千万年前形态各异的庞大家族数千万年后学会飞翔飞向蓝天身体变小长出羽毛一种是树栖的恐龙在树林之间跳跃、降落,慢慢具备了滑翔的能力,并最终能够主动飞行;另一种是生活在地面上的带羽毛的恐龙,在奔跑过程中学会了飞翔。对于恐龙“飞行”问题,作者给出了哪两种推测?提出假说寻找证据演化过程美好愿望亿万年前,一种带羽毛的恐龙脱离同类,飞向蓝天,演化出今天的鸟类大家族。科学家们希望能够全面揭示这一历史进程。指的是恐龙家族中的一支——猎食性恐龙长出羽毛、学会飞翔,演化为鸟类的漫长历史过程。怎么理解这句话?这句话是说科学工作者十分希望在现有资料与条件的基础上,力争通过科学技术手段,将其演变的全过程形象直观地展现在世人面前。科学家们希望能够全面揭示这一历史进程。第一种恐龙庞大家族猎食性恐龙

演变成鸟类科学发现恐龙演变成鸟类:令人惊奇科学发现历史进程飞向蓝天的恐龙演变过程美好的愿望:重现恐龙演变成鸟类的

历史进程19世纪:提出假说20世纪:辽西大发现板书设计课堂小结本文再现了恐龙变成鸟类飞向蓝天的演化过程,既揭示了科学家们在古生物研究方面的重大发现,唤起我们探索科学的兴趣,又向我们开启了一扇探索古生物的科学之门。拓展延伸拓展一拓展二恐龙之最:世界上最高最重的恐龙——极龙世界上最长的恐龙——地震龙世界上头骨最大的恐龙——牛角龙世界上蛋最大的恐龙——高脊龙拓展一返回始祖鸟始祖鸟是一些有羽毛印痕的兽脚类恐龙化石标本的统称,曾经被认为是最早及最原始的鸟类。1862年,始祖鸟化石的发现似乎确认了达尔文的理论,并从此成为恐龙与鸟类之间的关系、过渡性化石及演化的重要证据。拓展二返回穿越时空suìdào(),人们发现:有些恐龙bènzhònɡ()、chídùn(),重达数十dūn();有些恐龙则身材小巧,脑颅pénɡ()大,前zhī()越来越长,能像鸟yì()一样拍打。一、读句子,在语境中写字词。隧道随堂练习笨重迟钝吨膨肢翼早在19世纪,英国学者赫胥黎就注意到恐龙和鸟类在骨骼结构上有许多相似之处。在研究了大量恐龙和鸟类化石之后,科学家们提出,鸟类()和恐龙有亲缘关系,()很可能就是一种小型恐龙的后裔。二、课内阅读。而且不仅根据这一假说,一些与鸟类亲缘关系较近的恐龙应该长有羽毛,但相关化石一直没有被找到。在括号里填上合适的关联词。早在19世纪,英国学者赫胥黎就有了什么发现?恐龙和鸟类在骨骼结构上有许多相似之处。三、课外阅读。自然界有趣的现象有人特别爱观察,在自然界发现了许多有趣的现象。

加拿大的作物管理专家比特曼曾研究发现,生长的西红柿在缺水时会发出“呼喊”,如果“呼喊”后得不到水“喝”,“呼喊”就变成了“呜咽”。他解释说,这种声音是那些从根部向叶子传输水分的导管在萎缩时发出的,萎缩的力量相当于轮胎气压的25倍,会造成含有水分的导管破裂,从而发出“哭泣”的声音。对于植物为什么会像动物一样“哭泣”,美国科学家从化学的角度作出了解释。他们认为,当植物生存受到威胁或直接危害时,体内的亚麻酸就会发生变化,转化为茉莉酮酸,同样能帮助植物抵御外界的侵袭,茉莉酮酸的产生,就是植物“哭泣”的物质原因,也是抑制“疼痛”和医治创伤的良药。……根据短文,在下边正确的说法后面画“√”。西红柿在生长时“哭泣”,是因为有人伤害了它。()美国的科学家从化学的角度对“哭泣”作了解释。()植物“哭泣”,是因为体内的茉莉酮酸转化成了亚麻酸。()√复述恐龙飞向蓝天的演化过程。搜集关于恐龙的资料,做成知识卡片。课后作业第1课时第2课时故事导入一个夏日的正午,一只小苍蝇飞累
