作者為什么要這樣詳細地介紹恐龍的“龐大家族”？說明恐龍飛向藍天的演化過程。在復述文章內容的時候，思維導圖會有很大的幫助。請用思維導圖的形式，簡要概述恐龍飛向藍天，演化成鳥類的過程。恐龍第一種恐龍兩億四千萬年前形態各異的龐大家族數千萬年后學會飛翔飛向藍天身體變小長出羽毛一種是樹棲的恐龍在樹林之間跳躍、降落，慢慢具備了滑翔的能力，并最終能夠主動飛行；另一種是生活在地面上的帶羽毛的恐龍，在奔跑過程中學會了飛翔。對于恐龍“飛行”問題，作者給出了哪兩種推測？提出假說尋找證據演化過程美好愿望億萬年前，一種帶羽毛的恐龍脫離同類，飛向藍天，演化出今天的鳥類大家族。科學家們希望能夠全面揭示這一歷史進程。指的是恐龍家族中的一支——獵食性恐龍長出羽毛、學會飛翔，演化為鳥類的漫長歷史過程。怎么理解這句話？這句話是說科學工作者十分希望在現有資料與條件的基礎上，力爭通過科學技術手段，將其演變的全過程形象直觀地展現在世人面前。科學家們希望能夠全面揭示這一歷史進程。第一種恐龍龐大家族獵食性恐龍

歷史進程19世紀：提出假說20世紀：遼西大發現板書設計課堂小結本文再現了恐龍變成鳥類飛向藍天的演化過程，既揭示了科學家們在古生物研究方面的重大發現，喚起我們探索科學的興趣，又向我們開啟了一扇探索古生物的科學之門。拓展延伸拓展一拓展二恐龍之最：世界上最高最重的恐龍——極龍世界上最長的恐龍——地震龍世界上頭骨最大的恐龍——牛角龍世界上蛋最大的恐龍——高脊龍拓展一返回始祖鳥始祖鳥是一些有羽毛印痕的獸腳類恐龍化石標本的統稱，曾經被認為是最早及最原始的鳥類。1862年，始祖鳥化石的發現似乎確認了達爾文的理論，并從此成為恐龍與鳥類之間的關系、過渡性化石及演化的重要證據。拓展二返回穿越時空suìdào（），人們發現：有些恐龍bènzhònɡ（）、chídùn（），重達數十dūn（）；有些恐龍則身材小巧，腦顱pénɡ（）大，前zhī（）越來越長，能像鳥yì（）一樣拍打。一、讀句子，在語境中寫字詞。隧道隨堂練習笨重遲鈍噸膨肢翼早在19世紀，英國學者赫胥黎就注意到恐龍和鳥類在骨骼結構上有許多相似之處。在研究了大量恐龍和鳥類化石之后，科學家們提出，鳥類（）和恐龍有親緣關系，（）很可能就是一種小型恐龍的后裔。二、課內閱讀。而且不僅根據這一假說，一些與鳥類親緣關系較近的恐龍應該長有羽毛，但相關化石一直沒有被找到。在括號里填上合適的關聯詞。早在19世紀，英國學者赫胥黎就有了什么發現？恐龍和鳥類在骨骼結構上有許多相似之處。三、課外閱讀。自然界有趣的現象有人特別愛觀察，在自然界發現了許多有趣的現象。

加拿大的作物管理專家比特曼曾研究發現，生長的西紅柿在缺水時會發出“呼喊”，如果“呼喊”后得不到水“喝”，“呼喊”就變成了“嗚咽”。他解釋說，這種聲音是那些從根部向葉子傳輸水分的導管在萎縮時發出的，萎縮的力量相當于輪胎氣壓的25倍，會造成含有水分的導管破裂，從而發出“哭泣”的聲音。對于植物為什么會像動物一樣“哭泣”，美國科學家從化學的角度作出了解釋。他們認為，當植物生存受到威脅或直接危害時，體內的亞麻酸就會發生變化，轉化為茉莉酮酸，同樣能幫助植物抵御外界的侵襲，茉莉酮酸的產生，就是植物“哭泣”的物質原因，也是抑制“疼痛”和醫治創傷的良藥。……根據短文，在下邊正確的說法后面畫“√”。西紅柿在生長時“哭泣”，是因為有人傷害了它。（）美國的科學家從化學的角度對“哭泣”作了解釋。（）植物“哭泣”，是因為體內的茉莉酮酸轉化成了亞麻酸。（）√復述恐龍飛向藍天的演化過程。搜集關于恐龍的資料，做成知識卡片。課后作業第1課時第2課時故事導入一個夏日的正午，一只小蒼蠅飛累
