Reading(II)

內(nèi)容分析：

【W(wǎng)hat】本板塊的話題為“基因組編輯”，語(yǔ)篇來(lái)自一位生物學(xué)家的演講稿。演講者首

先介紹了基因和基因組的概念和作用；然后描述了基因組編輯技術(shù)如何用以治療和預(yù)

防種種疾病；隨后話鋒一轉(zhuǎn)，點(diǎn)出這一技術(shù)的不正當(dāng)使用可能引發(fā)道德等層面的問(wèn)題;

最后展望未來(lái)，對(duì)基因組編輯這一革命性的醫(yī)學(xué)技術(shù)予以肯定。

【W(wǎng)hy】演講者清晰而鮮明地表達(dá)了對(duì)基因組編輯技術(shù)的態(tài)度：一方面是肯定、興奮,

另一方面則是嚴(yán)肅、謹(jǐn)慎。對(duì)尖端科技的解釋和展望有助于學(xué)生了解醫(yī)學(xué)進(jìn)步對(duì)人類(lèi)

生命健康和未來(lái)社會(huì)發(fā)展的重要意義和積極影響，激發(fā)學(xué)生的創(chuàng)新精神；對(duì)這項(xiàng)技術(shù)

潛在風(fēng)險(xiǎn)的分析則提醒學(xué)生要理性思考，以嚴(yán)謹(jǐn)、科學(xué)的態(tài)度辯證地看待醫(yī)學(xué)發(fā)展，

學(xué)會(huì)尊重生命、尊重科學(xué)。

[How]本文的語(yǔ)篇類(lèi)型是演講稿。演講標(biāo)題既點(diǎn)明主旨又飽含深意；演講者由淺入

深、循序漸進(jìn)地為聽(tīng)眾呈現(xiàn)了生物醫(yī)學(xué)的相關(guān)知識(shí)，主題鮮明，脈絡(luò)清晰。在語(yǔ)言特

點(diǎn)上，演講者采用了簡(jiǎn)明通俗的語(yǔ)言對(duì)“基因”“基因組編輯”“設(shè)計(jì)嬰兒”等科學(xué)名詞進(jìn)

行相應(yīng)的解釋?zhuān)⒍啻尾捎门e例、反問(wèn)、比喻等手法闡明道理，激發(fā)聽(tīng)眾對(duì)話題的興

趣。學(xué)習(xí)本篇有助于學(xué)生掌握演講的格式和特點(diǎn)，有意識(shí)地用英語(yǔ)來(lái)學(xué)習(xí)其他學(xué)科的

【設(shè)計(jì)意圖：明確語(yǔ)篇特點(diǎn)，鍛煉寫(xiě)作技能。】

ExtendedReading:Acupuncture:magicneedles

內(nèi)容分析：

[What]本板塊的語(yǔ)篇是選自健康雜志的說(shuō)明文，介紹了一項(xiàng)中國(guó)傳統(tǒng)醫(yī)術(shù)——針

灸。文章詳細(xì)講解了針灸的演變歷史、診療過(guò)程以及針灸所能醫(yī)治的疾病和其原理猜

想，并指出針灸作為中華優(yōu)秀傳統(tǒng)文化的一個(gè)符號(hào)已經(jīng)擁有世界范圍內(nèi)的影響力，使

學(xué)生在獲得對(duì)針灸的基本認(rèn)識(shí)之余還能夠感受傳承千年的中華優(yōu)秀傳統(tǒng)文化的魅力。

[Why]本板塊的語(yǔ)篇通過(guò)對(duì)針灸的介紹，旨在幫助學(xué)生了解博大精深的中國(guó)傳統(tǒng)醫(yī)

學(xué)，堅(jiān)定文化自信；通過(guò)說(shuō)明針灸對(duì)世界的影響，使學(xué)生懂得弘揚(yáng)和發(fā)展中華優(yōu)秀傳

統(tǒng)文化的重要性和必要性。

【How］本板塊的語(yǔ)篇是一篇說(shuō)明文，結(jié)構(gòu)清晰：作者首先說(shuō)明了針灸作為一項(xiàng)古老

的醫(yī)術(shù)有著悠久的歷史；其次介紹了針的材質(zhì)和形態(tài)隨著歷史發(fā)展和科技進(jìn)步而不斷

變化；隨后陳述了針灸診療過(guò)程中采取的傳統(tǒng)中醫(yī)望、聞、問(wèn)、切等診療方法，以及

相關(guān)的醫(yī)學(xué)名詞，如“經(jīng)脈”“穴位”等；接著說(shuō)明針灸不僅可以診治身體疾病，對(duì)一些

心理問(wèn)題甚至不良嗜好也有一定作用；最后指出雖然針灸背后的醫(yī)學(xué)原理還沒(méi)有統(tǒng)一

的結(jié)論，但其對(duì)傳統(tǒng)中醫(yī)乃至世界醫(yī)學(xué)都有著獨(dú)特貢獻(xiàn)和深遠(yuǎn)影響。文章主題明確，

詳略得當(dāng)；作者運(yùn)用簡(jiǎn)潔明了的語(yǔ)言說(shuō)明了針灸的神奇之處。
