diseases”可知,他們的研究完全是為了制造針對人類疾病的非人類靈長類動物模型。由此可以推知,他們這么做是為了研究人類疾病。故C選項(xiàng)正確。27.【解析】選D。推理判斷題。根據(jù)倒數(shù)第二段中的“Still,theresearchprocessproveddifficult,andmanyattemptsbytheteamfailed.Justtwohealthybabymonkeyswerebornfrommorethan60testedmothers.”可知,研究過程被證明是困難的,而且小組的許多嘗試都失敗了。60多名接受測試的母猴子只生了兩只健康的小猴子。由此可知,克隆猴子的成功率并不高。故D選項(xiàng)正確。C【文章大意】本文屬于說明文。作者通過這篇文章向我們介紹了大象很少患癌癥的原因,這對人類治療癌癥有非常重要的意義。28.【解析】選D。細(xì)節(jié)理解題。由文章第三段第二句話“AteamattheUniversityofChicago,UShasfoundthatelephantscarryalargenumberofgenesthatstoptumorsfromdeveloping.”可知,大象攜帶大量能夠阻止腫瘤發(fā)展的基因。故正確答案為D。29.【解析】選A。細(xì)節(jié)理解題。由文章第五段第一句話“‘Anincreasedriskofdevelopingcancerhasstoodinthewayoftheevolutionoflargebodysizesinmanyanimals,’studyauthorDr.VincentLynchtoldTheGuardian.”可知,癌癥風(fēng)險的增加阻礙了大型動物的進(jìn)化。故正確答案為A。30.【解析】選B。細(xì)節(jié)理解題。根據(jù)文意與邏輯推理可知,“Thisphenomenon”指代上文中的“theriskofcancerdoesnotshowaconnectionwithbodymass.”即癌癥的風(fēng)險與體塊沒有關(guān)系。故正確答案為B。31.【解析】選D。細(xì)節(jié)理解題。由文章倒數(shù)第三段第一句話“Thestudyalsofoundthatwhenthesamegeneswerebroughttolifeinmice,theyhadthesamecancerresistanceaselephants.”可知,將同樣的基因轉(zhuǎn)入老鼠的體內(nèi),它們也能像大象一樣擁有癌癥抗體,同樣的基因指的是TP53基因。故選D。D【文章大意】本文是一篇說明文,主要介紹了西紅柿是如何從不被人們接受到一步步被世界各地的人們歡迎的。32.【解析】選A。主旨大意題。通讀全文可知,本文主要介紹了西紅柿是如何從不被人們接受到一步步被世界各地的人們廣泛接受的,也就是介紹了人們對西紅柿的看法是如何改變的,故A項(xiàng)正確。33.【解析】選C。細(xì)節(jié)理解題。根據(jù)第二段中的“Thetomatoplantlookedsimilartothenightshadeplant,adeadlypoison,sotheywereafraidtoeatthem.”可知,西紅柿看起來像龍葵,一種致命的毒藥;再根據(jù)“Germanpeopleeventhoughtthatifsomeoneatetomatoes,heorshewouldchangeintoawerewolf”可知,德國人甚至認(rèn)為吃了西紅柿后會變成狼人,以上是人們不敢吃西紅柿的原因,而文章沒有提到人們不敢吃西紅柿是因?yàn)槲骷t柿的種植成本高,故C項(xiàng)正確。34.【解析】選B。細(xì)節(jié)理解題。根據(jù)第三段中的“ButinAmerica,thetomatoisavegetablebylaw.”可知,在美國,西紅柿被認(rèn)為是一種蔬菜,故B項(xiàng)正確。35.【解析】選B。細(xì)節(jié)理解題。根據(jù)最后一段中的“Infact,tomatoesaresimilartostrawberries.Bothhaveseedsinside”可知,西紅柿和草莓的內(nèi)部很像,里面都有種子,故B項(xiàng)正確。第二節(jié)(共5小題;每小題2.5分,滿分12.5分)閱讀下面短文,從短文后的選項(xiàng)中選出可以填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)?！疚恼麓笠狻勘疚氖且黄f明文,介紹了養(yǎng)寵物能讓你的生活變得更美好的幾點(diǎn)原因。36.【解析】選G。根據(jù)本段小標(biāo)題“Apet’sloveneverstops.”可知,寵物的愛永遠(yuǎn)不會停止,故G項(xiàng)(無論如何,你的寵物會永遠(yuǎn)愛你,記得你)符合語境。37.【解析】選C。根據(jù)本段中的“regularwalksisalsogoodforyourheartandbrainhealth.”可知,遛狗對心腦健康有益,故C項(xiàng)(養(yǎng)寵物也有益于身體健康)符合語境。38.【解析】選A。根據(jù)本空后的“butnoticehowyoufeelwhenthetwoofyouareexchangingemotionalenergy.”可知,你不必把收容所里的寵物帶回家,但請注意你們情感交流時的感受,故A項(xiàng)(你不必把它帶回家)符合語境。39.【解析】選F。根據(jù)本空后的“butwhatabouttheusedones?Allmyanimalshavebeenrescued,andtheyareassweetascanbe.”可知,我所有的寵物都是救回來的,它們都非?？蓯?此處應(yīng)該會提到另一種寵物來源,故F項(xiàng)(有些人寧愿他們的小狗來自于寵物店)符合語境。40.【解析】選D。上文介紹了養(yǎng)寵物的好處,再根據(jù)本空前的“Youmayalreadyhaveafamilytolove”可知,也許你已經(jīng)有了家庭之愛,此處總結(jié)上文,故D項(xiàng)(如果你想要生活中有更多的愛,考慮養(yǎng)一只寵物)符合語境。第三部分語言運(yùn)用(共兩節(jié),滿分30分)第一節(jié)(共15小題;每小題1分,滿分15分)閱讀下面短文,從每題所給的A、B、C、D四個選項(xiàng)中選出可以填入空白處的最佳選項(xiàng)。【文章大意】本文是一篇記敘文。文章通過作者在媽媽的保護(hù)下學(xué)舞蹈的故事,告訴我們“永遠(yuǎn)不要害怕去摘星星,因?yàn)榧词鼓愕粝聛砹?你仍然會有父母保護(hù)著?！?1.【解析】選C?？疾槊~。teacher教師;director導(dǎo)演,指導(dǎo)者;dancer舞蹈家;musician音樂家。我的母親是一名舞蹈演員,我只想成為她那樣的人,但在第一堂課上把事情搞砸后,我覺得我想馬上放棄。故選C。42.【解析】選A?？疾閯釉~詞組。messingup混亂;makingup組成,構(gòu)成;keepingup繼續(xù),保持;pickingup拾起,接收到。我的母親是一名舞蹈演員,我只想成為她那樣的人,但在第一堂課上把事情搞砸后,我覺得我想馬上放棄。故選A。43.【解析】選B?？疾楦痹~。besides另外,此外;however然而;therefore因此;otherwise要不然的話。然而,因?yàn)檫@只是我第一天上芭蕾課,我告訴媽媽我迫不及待地要再跳舞了。前后是一種轉(zhuǎn)折關(guān)系,故選B。44.【解析】選B?？疾閯釉~。standing站立;falling落下;putting放;dancing跳舞。所以,當(dāng)我的舞蹈老師宣布我們要在一個節(jié)目中表演時,我害怕在幾百人面前丟臉,讓我媽媽失望?？芍鸢笧锽。45.【解析】選A。考查形容詞。disappointing令人失望的;satisfying令人滿意的;moving令人感動的;contusing挫傷的。所以,當(dāng)我的舞蹈老師宣布我們要在一個節(jié)目中表演時,我害怕在幾百人面前丟臉,讓我媽媽失望。故選A。46.【解析】選B?？疾樾稳菰~。enthusiastic充滿熱情的;embarrassed尷尬的;understanding理解的;curious好奇的。最后,我感到緊張和尷尬,我去我媽媽那里告訴她我的感受。故選B。47.【解析】選C。考查形容詞。important重要的;interesting有趣的;impossible不可能的;unnecessary不必要的。我一邊哭,一邊告訴她我不可能跳舞。故選C。48.【解析】選B?？疾槊~。sweat汗水;tears眼淚;fear害怕;surprise驚訝。她擦去我臉上的淚水,我笑了。故選B。49.【解析】選D?？疾槊~。courage勇氣;boredom厭煩;imagination想象;patience耐心。媽媽很快就發(fā)現(xiàn)我的芭蕾有多差,但她仍然以最大的耐心、愛心和理解來教我。故選D。50.【解析】選A?？疾槊~。balance平衡;interest興趣;confidence自信;protection保護(hù)。我失去平衡時,她扶著我。故選A。51.【解析】選B?？疾槊~。music音樂;show演出;audience觀眾;meeting會議。演出開始的時候,我已經(jīng)做好了充足的準(zhǔn)備。故選B。52.【解析】選A?？疾閯釉~。missing錯過;taking拿走,帶走;counting計(jì)算,計(jì)數(shù);watching觀看。我穩(wěn)穩(wěn)地呼吸著,隨著音樂一步一步地移動。故選A。53.【解析】選D。考查名詞。turn轉(zhuǎn)變;return歸還;peace和平;excitement興奮。當(dāng)音樂停止時,我跑下舞臺,興奮地笑了。故
