B．Disapproving.C．Supportive. D．Doubtful.答案：B推理判斷題。根據(jù)最后一段內(nèi)容可知，Milutinovicht認(rèn)為庇護(hù)所里有很多狗等著被領(lǐng)養(yǎng)，需要一個(gè)充滿愛的家，為什么要去克隆已經(jīng)死了的寵物呢？說明他對這一現(xiàn)象持反對態(tài)度。故選B。Chinabecamethefirstcountrytocloneamonkeyusingnonreproductivecells,scientistssaidonThursday.ByDecember2017,theChineseAcademyofScienceshadcreatedtwoclonemacaques(獼猴)named“Zhongzhong”and“Huahua”bynucleartransferringofbodycells—anycellintheorganismotherthanreproductivecells.ThiswasthesimilartechnologyusedtocreatethefamousclonesheepDollyin1996.Telra,amonkeybornin1999,wastheworld'sfirsteverclonedmonkey,butitwasdoneusingasimplermethodcalledembryosplitting(胚胎分裂),andcouldn'tbegeneticallymodifiedtosuitexperimentalneeds,saidPuMuming,aleadingresearcherattheChineseAcademyofSciences.“Cloningamonkeyusingbodycellshasbeenaworldclasschallengebecauseitisaprimate(靈長類)thatsharesitsgeneticmakeupandallofitscomplexitywithhumans，”hesaid.“Fordrugandotherlabtests,scientistshavetopurchasemonkeysfromallovertheworld,whichiscostlyandbadfortheenvironmentandproducesinaccurateresultsbecauseeachmonkeymighthavedifferentgenes，”Pusaid.“Bycloningamonkeyusingbodycells,wecanreproducealargenumberofgeneticallyidenticalmonkeysinashortamountoftime,andwecanevenchangetheirgenestosuitourneeds，”headded.“Thiscansavetime,cutdownexperimentcosts,andproducemoreaccurateresults,leadingtomoreeffectivemedicine.”SunQiang,directorofthenonhumanprimateresearchfacilityattheinstitute,saidmostofthedrugtrialswerecurrentlydoneonlabmice.However,drugsthatworkonmicemightnotworkorevenhaveseveresideeffectsonhumansbecausethetwospeciesaresodifferent.Monkeysandhumansarebothprimates,sotheyarecloselyrelatedandtestingonmonkeysissupposedtobeaseffectiveastestingonhumans.ThisachievementwillhelpChinaleadtheworldresearchinaninternationalscienceprojectrelatedtostudyofprimatebrains.篇章導(dǎo)讀：本文是一篇科普類說明文。文章講述了中國在克隆技術(shù)上取得的成就——中國是第一個(gè)使用非生殖細(xì)胞克隆獼猴的國家。5．Whatdoweknowaboutthetwoclonemacaques?A．Theywerethefirstmonkeyseverclonedintheworld.B．Theywerecreatedusingreproductivecells.C．Theywouldbefedtosuitexperimentalneeds.D．ThetechnologyusedtocreatethemwassimilartothatofcreatingDolly.答案：D細(xì)節(jié)理解題。根據(jù)第一段最后一句“ThiswasthesimilartechnologyusedtocreatethefamousclonesheepDollyin1996.”可知，克隆獼猴使用的技術(shù)與著名的克隆羊多莉使用的技術(shù)是相似的。6．Whichofthefollowingcanreplacetheunderlinedword“identical”inthefourthparagraph?A．Same. B．Similar.C．Relevant. D．Close.答案：A詞義猜測題。通過閱讀畫線詞所在段落可知，該段與上一段內(nèi)容形成對照，上一段敘述了由于猴子基因不同造成的壞處，本段講述了各種好處原因是用這種方法可以復(fù)制出基因相同的猴子，據(jù)此推斷，畫線詞意為“相同的”，故選A。7．Whatcanbelearnedfromthepassage?A．PuMumingandSunQiangweredoingmostworkincloningthetwomacaques.B．Geneticresearchonmonkeyscanbeseenaseffectiveasthatonhumans.C．Micesharethesamegeneticmakeupandcomplexitywithhumans.D．Scientistscanreproduceclonedmonkeystocutdownexperimentcosts.答案：B推理判斷題。根據(jù)最后一段第一句“Monkeysandhumansarebothprimates,sotheyarecloselyrelatedandtestingonmonkeysissupposedtobeaseffectiveastestingonhumans.”可知，猴子和人都是靈長類，他們關(guān)系密切，因此對于猴子的基因研究應(yīng)該與對人類的研究一樣有效。8．Thispassageabovecanbemostprobablyreadin________.A．a(chǎn)sciencemagazine B．a(chǎn)guidebookC．a(chǎn)storybook D．a(chǎn)brochure答案：A推理判斷題。縱觀全文可知，本文主要講述克隆技術(shù)方面的研究成果，中國成功用非生殖細(xì)胞克隆出獼猴。因此推斷文章很可能在科技雜志上找到。Ⅲ.短文改錯(cuò)(2019·遼寧省五校協(xié)作高三聯(lián)合模擬題)DearJoy，Howareyoudoing?Hereisanexcitingnewsforyou.Therewillbeaninventioncompetitioninourschoolinthe20thofOctober.However,thereisaruletheparticipantsshallbeinagroup.ButI'dliketoinviteyoutobemypartners.Iknowthatyouhavebeenlongedtodesignatinycoolerthatpeoplecanweararoundthewrist.Ithinkitwillbeawonderfullyideaforthecompetition.Wecanmakeasmallairconditionertocontrollingthetemperatureofthewearer.Howdoyouthinkofmysuggestion?Lookingforwardtoyoureply.Yours，ZhangXin答案：DearJoy，Howareyoudoing?Hereiseq\o(eq\o(an,＼),\s\do16(①))excitingnewsforyou.Therewillbean
