Ⅶ.應(yīng)用文寫作(2023·遼寧撫順校聯(lián)考二模)假定你是李華,你的外國朋友John對中醫(yī)很感興趣,打算暑假來你市學(xué)習(xí)針灸(acupuncture)。請你給他寫一封郵件,向他介紹針灸并推薦一位針灸老師,內(nèi)容包括:1.簡介針灸;2.推薦老師;3.表達(dá)祝福。注意:1.詞數(shù)80左右;2.請在相應(yīng)位置作答。DearJohn,_________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Yours,LiHua參考答案Ⅰ.1.clone2.camel3.goat4.clues5.treatment6.biology7.Mammals8.forever9.reproductive10.emotionⅡ.1.parison5.wholly6.topass7.merely8.abused9.a10.fromⅢ.1.iscapableof2.breakthetechnicalbarrier3.makeanexactcopy4.incomparisonwith5.isboundtoshape6.ItisunknownwhetherⅣ.【語篇導(dǎo)讀】本文是議論文。文章主要討論了克隆的優(yōu)缺點。1.D細(xì)節(jié)理解題。由第二段中的“Itcanalsobringabouttherecreationofspeciesthathavelongsincedied,allowingscientiststofullystudythespeciesasalivingcreatureinsteadofsimplylookingatimagesorbones.”可知,生殖性克隆使得再創(chuàng)造已經(jīng)滅絕的物種成為可能,能夠讓科學(xué)家充分研究一個生物物種,而不是僅僅觀察這些滅絕物種的圖片和骨骼。故選D項。2.A細(xì)節(jié)理解題。由第三段中的“cloningcanbeusedtoreplacefailingorgans”可知,克隆可以用于替換衰竭的器官,故可用于器官移植。3.C細(xì)節(jié)理解題。由倒數(shù)第三段中的“itcouldalsocausealotofmalpractices”和“therecouldbethepossibilityofpeopledeliberatelyreproducingundesiredcharacters.Thiscouldleadtoariseinmalpracticeswithinsociety.”可知,克隆會導(dǎo)致社會中的不端行為增加。4.D推理判斷題。由最后一段中的“studiesshowthattheclonewouldinfactnotbecompletelyidenticaltotheoriginaljustastwinsarenotcompletelyidentical”可知,克隆體與母體并不是完全相同的;作者提到雙胞胎是為了說明克隆體與母體的差別。【語篇導(dǎo)讀】本文是議論文。文章討論了克隆技術(shù)以及克隆人的問題。5.B推理判斷題。根據(jù)第二段中的“Thestorythatgavepeoplecauseforconcern”及第三段中的“Alarmbellswentoffinmyhead.”和第四段中的“Isittimetoworryabouthumancloningagain?”可知,Must克隆逝世女兒的寵物狗一事讓作者感到非常擔(dān)憂。6.A推理判斷題。根據(jù)第五段中的“ImetCibelli15yearsago,whenIwasamongagroupofjournalistscoveringcloningnonstop...copyahumanbeingatanymoment.”可推斷,當(dāng)時克隆人的想法受到了人們的廣泛關(guān)注。7.C段落大意題。根據(jù)第六段中的“Inmanyanimals,onlyonein100clonedembryoseverleadstoalivebirth...andquicklydie.”可知,克隆過程中能最后成活的個體極少。由此可見,該段主要介紹了克隆人類所面臨的各種困難及挑戰(zhàn)。8.A細(xì)節(jié)理解題。根據(jù)最后一段中的“Shesaidit’snotaquestionshehasananswerto.”可知,Must對是否會克隆自己女兒的問題并沒有明確的答案。【語篇導(dǎo)讀】本文是記敘文。農(nóng)業(yè)科學(xué)家程相文用畢生的精力培育出雜交玉米,并且研發(fā)出14種高產(chǎn)的玉米新品種。9.D推理判斷題。根據(jù)第一段“‘Mybirthdaywishistodevelopbettercornvarieties,’hesays.”可知,程相文想要培育出高產(chǎn)的玉米品種。故選D項。10.B細(xì)節(jié)理解題。根據(jù)第二段內(nèi)容可知,在程相文做實地調(diào)查時,一位農(nóng)民的訴求讓他從那時起把培育高產(chǎn)玉米品種當(dāng)成畢生的事業(yè)。即在第二段說明了程的使命起源于什么。故選B項。11.C細(xì)節(jié)理解題。根據(jù)第四段內(nèi)容可知,程相文當(dāng)時在海南的生活環(huán)境和生活條件很差。故選C項。12.A推理判斷題。根據(jù)第四段內(nèi)容和最后一段中的“Chengisdedicatedtodevelopinghigh-yieldcornvarietieswithstrongerresistanceandtheyareeasiertoharvestwithmachines.Hestillgoestothefieldseachdayandobservesandrecordsthecornplants.”可知,程相文是一位認(rèn)真敬業(yè)、不畏艱難且意志堅定的
