B．Disapproving.C．Supportive. D．Doubtful.答案：B推理判断题。根据最后一段内容可知，Milutinovicht认为庇护所里有很多狗等着被领养，需要一个充满爱的家，为什么要去克隆已经死了的宠物呢？说明他对这一现象持反对态度。故选B。Chinabecamethefirstcountrytocloneamonkeyusingnonreproductivecells,scientistssaidonThursday.ByDecember2017,theChineseAcademyofScienceshadcreatedtwoclonemacaques(猕猴)named“Zhongzhong”and“Huahua”bynucleartransferringofbodycells—anycellintheorganismotherthanreproductivecells.ThiswasthesimilartechnologyusedtocreatethefamousclonesheepDollyin1996.Telra,amonkeybornin1999,wastheworld'sfirsteverclonedmonkey,butitwasdoneusingasimplermethodcalledembryosplitting(胚胎分裂),andcouldn'tbegeneticallymodifiedtosuitexperimentalneeds,saidPuMuming,aleadingresearcherattheChineseAcademyofSciences.“Cloningamonkeyusingbodycellshasbeenaworldclasschallengebecauseitisaprimate(灵长类)thatsharesitsgeneticmakeupandallofitscomplexitywithhumans，”hesaid.“Fordrugandotherlabtests,scientistshavetopurchasemonkeysfromallovertheworld,whichiscostlyandbadfortheenvironmentandproducesinaccurateresultsbecauseeachmonkeymighthavedifferentgenes，”Pusaid.“Bycloningamonkeyusingbodycells,wecanreproducealargenumberofgeneticallyidenticalmonkeysinashortamountoftime,andwecanevenchangetheirgenestosuitourneeds，”headded.“Thiscansavetime,cutdownexperimentcosts,andproducemoreaccurateresults,leadingtomoreeffectivemedicine.”SunQiang,directorofthenonhumanprimateresearchfacilityattheinstitute,saidmostofthedrugtrialswerecurrentlydoneonlabmice.However,drugsthatworkonmicemightnotworkorevenhaveseveresideeffectsonhumansbecausethetwospeciesaresodifferent.Monkeysandhumansarebothprimates,sotheyarecloselyrelatedandtestingonmonkeysissupposedtobeaseffectiveastestingonhumans.ThisachievementwillhelpChinaleadtheworldresearchinaninternationalscienceprojectrelatedtostudyofprimatebrains.篇章导读：本文是一篇科普类说明文。文章讲述了中国在克隆技术上取得的成就——中国是第一个使用非生殖细胞克隆猕猴的国家。5．Whatdoweknowaboutthetwoclonemacaques?A．Theywerethefirstmonkeyseverclonedintheworld.B．Theywerecreatedusingreproductivecells.C．Theywouldbefedtosuitexperimentalneeds.D．ThetechnologyusedtocreatethemwassimilartothatofcreatingDolly.答案：D细节理解题。根据第一段最后一句“ThiswasthesimilartechnologyusedtocreatethefamousclonesheepDollyin1996.”可知，克隆猕猴使用的技术与著名的克隆羊多莉使用的技术是相似的。6．Whichofthefollowingcanreplacetheunderlinedword“identical”inthefourthparagraph?A．Same. B．Similar.C．Relevant. D．Close.答案：A词义猜测题。通过阅读画线词所在段落可知，该段与上一段内容形成对照，上一段叙述了由于猴子基因不同造成的坏处，本段讲述了各种好处原因是用这种方法可以复制出基因相同的猴子，据此推断，画线词意为“相同的”，故选A。7．Whatcanbelearnedfromthepassage?A．PuMumingandSunQiangweredoingmostworkincloningthetwomacaques.B．Geneticresearchonmonkeyscanbeseenaseffectiveasthatonhumans.C．Micesharethesamegeneticmakeupandcomplexitywithhumans.D．Scientistscanreproduceclonedmonkeystocutdownexperimentcosts.答案：B推理判断题。根据最后一段第一句“Monkeysandhumansarebothprimates,sotheyarecloselyrelatedandtestingonmonkeysissupposedtobeaseffectiveastestingonhumans.”可知，猴子和人都是灵长类，他们关系密切，因此对于猴子的基因研究应该与对人类的研究一样有效。8．Thispassageabovecanbemostprobablyreadin________.A．asciencemagazine B．aguidebookC．astorybook D．abrochure答案：A推理判断题。纵观全文可知，本文主要讲述克隆技术方面的研究成果，中国成功用非生殖细胞克隆出猕猴。因此推断文章很可能在科技杂志上找到。Ⅲ.短文改错(2019·辽宁省五校协作高三联合模拟题)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
