選文首先提出論點(diǎn)，并初步論證了自然選擇客觀上存在可能性，事理上具有合理性，然后從物種最初的存在形式大量變種的存在、物種的演化與改良、生物的遺傳性與變異性、生物的地理分布等方面，列舉了大量科學(xué)考察所得到的事實(shí)，充分證明了自然選擇決定了生物進(jìn)化的方向這一觀點(diǎn)，有力地駁斥了物種特創(chuàng)論的觀點(diǎn)?；顒尤⒅髦?xì)w納及觀點(diǎn)明晰（1）《物種起源》提出人類和動物的祖先是一樣的，這一理念對西方社會和思想產(chǎn)生了深刻的影響，也是現(xiàn)代生物學(xué)和進(jìn)化論的基礎(chǔ)。（2）《物種起源》第一次把生物學(xué)建立在完全科學(xué)的基礎(chǔ)上，以全新的生物進(jìn)化思想，推翻了“神創(chuàng)論”和物種不變的理論。（3）《物種起源》是達(dá)爾文進(jìn)化論的代表作，標(biāo)志著進(jìn)化論的正式確立，是一本劃時(shí)代的科學(xué)巨著，是科學(xué)對宗教的勝利。了解《物種起源》的意義三、選文的藝術(shù)特色①知識的科學(xué)性：作者在文中援引了大量科學(xué)考察所得到的事實(shí)以及一些其他學(xué)科的研究成果，使自己的論證建立在科學(xué)的事實(shí)基礎(chǔ)之上，結(jié)論無可辯駁。②綜述的完備性：選文部分從生物物種的最初形態(tài)，到生物的習(xí)性、本能、遺傳與變異，以及物種的滅絕與地理分布，做了全面的論證。4.1歸納本文的藝術(shù)特色③態(tài)度的嚴(yán)謹(jǐn)性：作者在論證過程中，并沒有擺出生物學(xué)權(quán)威的姿態(tài)，對不了解的內(nèi)容坦然承認(rèn)。比如在談到自然選擇讓“自然界處處充滿著美”時(shí)，對“某些顏色、聲音和形態(tài)何以能給人及動物以愉悅”“最簡單的美感，最初是如何獲得的”等問題就沒有給出答案，而是坦然地說“這是很難搞清楚的”。④結(jié)論的明確性：擺事實(shí)，講道理，兼以與特創(chuàng)論的屢次對比，使結(jié)論鮮明而穩(wěn)固。4.2歸納本文的藝術(shù)特色四、拓展研究Clickheretoenteryourtext.Clickheretoenteryourtext.Clickheretoenteryourtext.Clickheretoenteryourtext.Clickheretoenteryourtext.Clickheretoenteryourtext.Clickheretoenteryourtext.Clickheretoenteryourtext.Clickheretoenteryourtext.Clickheretoenteryourtext.Clickheretoenteryourtext.Clickheretoenteryourtext.Clickheretoenteryourtext.Clickheretoenteryourtext.Clickheretoenteryourtext.Clickheretoentery
