限時提分練(十七)Ⅰ.閱讀理解A語篇類型：說明文主題語境：人與社會——科技與生活——運用基因編輯技術研制無籽或無核水果。【語篇解讀】該文主要介紹了運用基因編輯技術可以更快地研制出無籽或無核水果，但這種水果要想進入超市，可能必需符合與轉基因水果相同的標準。1．答案與解析：D考查細微環節理解。依據第三段中的“they'vetakenresearchersmanyyearstocreate”和第五段中的“ThesemethodstakelongertimecomparedwithCRISPR”可知，過去創建無籽西紅柿很耗時，故選D。2．答案與解析：A考查細微環節理解。依據第四段中的“HisteamusedtheCRISPRgene-editingtechnologyto...noseedshadbeguntoform”可知，KeishiOsakabe的團隊編輯了西紅柿的基因，故A項正確。3．答案與解析：B考查推理推斷。依據第八段中的“CRISPRcouldbeusedtodevelopothertypesoffruitthatdon'trequirepollinators”可知，CRISPR可用于研制其他類型的不須要傳粉者的水果。由此可推知，CRISPR不會受到沒有蜜蜂的影響，故選B。4．答案與解析：B考查詞義揣測。依據第七段中的“Seedlessplantsusuallyhavetobegrownfromcuttings,whichinvolvesmorelaborthanplantingseeds”可知，種植無籽植物通常須要投入更多勞動。由此可推知，這對農夫來說并不是什么好事，故畫線詞的含義與B項詞義最接近。danger“危急”，disadvantage“劣勢”，benefit“好處”，solution“解決方法”。B語篇類型：說明文主題語境：人與社會——社會進步——科技改善非洲農夫的生活狀況【語篇解讀】文章以EstherUsman為例介紹了非洲農夫在科技的幫助下生活狀況得以改善的狀況。5．答案與解析：C考查推理推斷。依據其次段中的“EstherUsman,fromKadunaState,NorthwestNigeria,hasbeengrowingcornsinceshewas17,whenshedroppedoutofschooltosupportherfamilyafterherfather'sdeath.Twodecadeson,shewasstruggling.Sheoftenlayawakeatnightworryingabouthowtofeedandeducateherchildren”可推斷，Usman在早年間雖然努力工作但過著貧困的生活。6．答案與解析：B考查細微環節理解。依據第三段中的“Andcorninstorageisoftenlosttomoisture(潮氣)andpests,whichisabigproblem”可知，Usman說貯存中的玉米常常會因為潮氣和害蟲而壞掉，因此對她來說收完玉米后的儲存是個問題，即儲存玉米是一個挑戰。故答案為B。7．答案與解析：D考查推理推斷。依據第四段中對fieldofficers的工作內容的介紹“FieldofficersemployedbyBabbanGonaphotographitsfarmers'fields...Thefieldofficersstepintowarnfarmersofanyproblemstheyfindandadviseonpossiblesolutions”可知，BabbanGona雇用的田地工作人員對農夫的田地進行拍照，一個應用程序審核這些照片并評估這些照片中的農作物，而后田地工作人員告知農夫他們發覺的任何問題，并就可能的解決方案提出建議。由此可推知，田地工作人員充當了農夫和這個公司之間的橋梁。8．答案與解析：A考查主旨大意。本文以EstherUsman為例介紹了科技幫助非洲農夫改善生活狀況，故答案為A。Ⅱ.七選五語篇類型：記敘文主題語境：人與自我——人物故事——母親的激勵【語篇解讀】一個男孩為成果不猶如桌而苦惱，問他的媽媽他是不是比別人笨。媽媽沒有正面回答男孩的問題而是帶他去了海邊，讓他留意笨拙的海鷗竟然是最終飛越大海的。后來，男孩以第一名的成果被一所好高校錄用。1．答案與解析：C依據空前的“‘Mom,amImorestupidthanothers?IfeelIamashardworkingashim,buthowcomeIalwaysfallbehind？’”可知，空處應是表述媽媽聽到男孩的提問后的反應，C項“聽了這些話，她說不出話來，不知道如何說明”符合語境，故C項正確。2．答案與解析：B依據空前的“thesamequestion”和空后一句“However，wasthisanswerinherson'sbestinterest？”可知，然而他的媽媽不知道這樣的回答是否對男孩有利。據此可知，空處應是表述媽媽想要回答男孩的問題，故B項正確。3．答案與解析：G依據空后一句“Toreducetheburdenonhersonwhowassufferingfromthepainsofunsatisfyinggradesandrankings，Mom
