But Shalise Leesfield isn't one ofthem. The Australian teenager couldn't think of a better creature to meet when scuba diving off the coast of South West Rocks, near her home in Port Macquarie, a coastal town north of Sydney. “Many people say gray nurse sharks look frightening, but I think they are the sweetest animals,” she says. The slow-moving sharks, which like to stay near the seafloor in warm, shallow waters, are—for the most part—harmless to humans. But the gray nurse shark is under threat. Populations have decreased and habitats have been lost due to ocean warming and human development, according to the International Union for Conservation of Nature(IUCN), which lists the species as seriously endangered. One area where they can still be seen is Fish Rock, an underwater cavern(大洞穴) with a unique ecosystem, 40 miles up the coast from Leesfield's home. But fishers are allowed access within 200 meters of Fish Rock. This is leading to a drop in the number of gray nurse sharks and is increasing pollution, says Leesfield. She wants to enlarge the no-fishing area, establishing a protected zone. With Leesfield's efforts, the area has been nominated as Hope Spot, which is part of the mission Blue Program launched by famous oceanographer Sylvia Earle that identifies places as critically important to the ocean's health and supports protection. “When people think about Hope Spot, they think about Sydney Harbour or the Great Barrier Reef. So to get Fish Rock up on that list is just such incredible news,” she says. Now, Leesfield is working with politician Cate Faehrmann, marine spokesperson for the Australian Greens in New South Wales, to legalize protection of the sharks and make the no-fishing zone protected by the law. 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 1.What does the underlined word “them” refer to in the first paragraph? A.Gray nurse sharks.　　　B.Common people. C.People fearing gray nurse sharks.　　　D.Fishers. 2.What has led to gray nurse sharks' being seriously endangered? A.The development of tourism in the ocean. B.The sharks' preference to stay in shallow waters. C.The feature of gray nurse sharks' slow movement. D.Fishers' being permitted within 200 meters of Fish Rock. 3.What will Leesfield and Faehrmann do to protect gray nurse sharks? A.Recommend Fish Rock as Hope Spot being protected. B.Identify the Hope Spot area as critically important. C.Make Fish Rock more popular among nearby fishers. D.Make laws to protect the no-fishing zone near Fish Rock. 4.Which can be the best title of the article? A.The Australian teenager is on a mission to protect gray nurse sharks B.Increased pollution leads to gray nurse sharks being endangered C.Gray nurse sharks are in danger D.Let's establish a protected zone Ⅱ.七选五 (2026河南南阳六校期中联考)(拓展语篇) There's magic in travel, and it's obvious. Whether you're flying to a dream place or taking a road trip, the joy of travel has a way of lighting up your soul. 　1　 It's not just the change of scenery or the chance to escape your daily life—though those help! Let's explore the deeper reasons behind why travel brings us so much happiness.  Life can sometimes feel like a never-ending cycle of responsibilities—work, chores, and commitments. 　2　 That freedom fuels a sense of relaxation and adventure, relieving stress and boosting your mood. Plus, breaking free from routine helps you appreciate the little things when you return home.   Travel brings you closer to people, whether by bringing you closer to travel partners or by making friends with locals. 　3　 Human connection is a fundamental source of happiness, and travel is the perfect avenue(方法) for it.  Stepping into unfamiliar places can be discouraging, but with each new trip, you grow more confident in your ability to deal with the unknown. Whether it's figuring out a new subway system, or overcoming a language problem, travel challenges you to be resourceful and adaptable. 　4　  　5　 When you're standing before a breathtaking sunset, wandering through busy markets, or hiking up a mountain trail, it's hard to think about anything else. This presence in the moment is a key contributor to happiness, as it reduces anxiety and allows you to fully appreciate the beauty around you.  A.Travel pulls you into the present. B.The more you explore, the more insignificant you feel. C.Travel exposes you to new sights, sounds, and cultures. D.But have you ever wondered why it makes you so happy? E.And with every challenge you overcome, your confidence grows. F.Travel allows you to escape into a world free of deadlines and alarms. G.These connections often result in unforgettable stories and precious memories. 1.　　　　　　 2.　　　　　　 3.　　　　　　 4.　　　　　　 5.　　　　　　  Ⅲ.完形填空 (2024广东惠州期末) Clark, a bald eagle(秃鹰), is a frequent commercial flier. He takes at least six trips a year. When the plane touches down, the 　1　 will often announce to the cabin, “The bald eagle has 　2　.”  Like many passengers who touch down in the nation's capital, Clark has a pretty high profile. His eagle father, Captain, was given as a 　3　 to the United States in 1982 by West Germany. At the time, the bald eagle was endangered, and environmentalists were 　4　 about the present. At its low point, the bald eagle population had fallen to 417 known nesting pairs.  The United States made great efforts to 　5　 the bald eagle population and the result was 　6　. The species was saved and it was 　7　 from the list of threatened species in 2007.  Captain was part of a critical conservation breeding program, 　8　 six healthy eaglets(雏鹰). While Clark's siblings were 　9　 into the wild, Clark has spent his whole life under human care. Clark's claw(爪) did not form 　10　 and just didn't give him the 　11　 that he would need. After all, the wild is not the most 　12　 place.  Clark travels across the country to 　13　 flight demonstrations and other educational programs at events. People react similarly when they see him at events. They're 　14　. Clark's physical presence leaves a lasting impression and 　15　 people to care more about conservation efforts.  　　　　　　　　　　　　　　　 1.A.driver　　　B.passenger C.pilot　　　D.conductor 2.A.boarded　　　B.landed C.left　　　D.launched 3.A.gift　　　B.decoration C.product　　　D.reward 4.A.passionate　　　B.concerned C.excited　　　D.curious 5.A.keep　　　B.monitor C.study　　　D.recover 6.A.satisfactory　　　B.scary C.discouraging　　　D.convincing 7.A.excused　　　B.protected C.removed　　　D.separated 8.A.teaching　　　B.fathering C.catching　　　D.adopting 9.A.thrown　　　B.changed C.divided　　　D.freed 10.A.carefully　　　B.beautifully C.formally　　　D.properly 11.A.necessity　　　B.company C.protection　　　D.opportunity 12.A.secret　　　B.forgiving C.striking　　　D.impressive 13.A.learn　　　B.seek C.observe　　　D.perform 14.A.blown away　　　B.put away C.taken away　　　D.hidden away 15.A.encourages　　　B.trains C.forces　　　D.warns 答案与分层梯度式解析 UNIT 3　CONSERVATION Part 1　TOPIC TALK 基础过关练 Ⅰ.1.items　2.plastic;recycled Ⅱ.1.were bad for　2.have a role　3.cut down　4.work on　5.Do your part Ⅲ.1.incredibly　考查副词。句意:在科学领域,由好奇心驱动的研究——在没有立即产生实际成果的压力下进行的研究——可能会带来意想不到且极其重要的益处。设空处位于形容词important之前,修饰该形容词,应用副词形式。故填incredibly,表示“极其,非常”。 2.destruction　考查名词。由空前的定冠词the和空后的介词of可知本空填名词。故填destruction。 3.on　考查介词。switch on为固定搭配,意思是“打开”。 4.informative　考查形容词。空前有修饰形容词或副词的so,且前面有is,因此本空填形容词作表语。 5.illegally　考查副词。设空处位于staying后面,故推测此处为副词作状语,修饰staying。故填illegally。 6.to hunt　考查动词不定式。分析句子可知此处为“It is+adj.+for sb. to do sth.”句型,hunters与hunt之间为主动关系,所以此处应填to hunt。 7.which　考查定语从句。分析句子可知,设空处引导非限制性定语从句,先行词为前面整句话,故填which。 8.extinction　考查名词。空前是介词of,因此设空处用名词形式。故填extinction。 9.to　考查介词。threat后跟介词to,表示“对……的威胁”。 10.urgently　考查副词。此处修饰动词-ing形式,应用副词,urgently 意为“紧急地,急迫地”。 Ⅳ.1.has a role to play in this project　2.I can see that　3.that she is for me　4.If you work hard 能力提升练 Ⅰ.语篇解读　本文是一篇记叙文。文章讲述澳大利亚少年Shalise Leesfield致力于保护灰护士鲨的故事。 【高频词汇】　1.creature n.生物,动物 　2.habitat n.(动植物的)生活环境,栖息地　3.establish v.建立,确立　4.identify v.确认;找到,发现 【差距词汇】　1.scuba dive戴水肺潜水　2.ecosystem n.生态系统　3.enlarge v.扩大,增大　4.nominate v.提名,推荐;任命;指定　5.legalize v.使合法化 长难句 原句　With Leesfield's efforts, the area has been nominated as Hope Spot, which is part of the mission Blue Program launched by famous oceanographer Sylvia Earle that identifies places as critically important to the ocean's health and supports protection. 分析　本句为主从复合句。which引导非限制性定语从句;launched by famous oceanographer Sylvia Earle是过去分词短语作后置定语,修饰Blue Program;that引导定语从句,修饰先行词Blue Program。 译文　在Leesfield的努力下,该地区被提名为Hope Spot,这是著名海洋学家Sylvia Earle发起的蓝色计划的一部分,该计划确定对海洋健康至关重要的地方,并支持保护。 1.C　词义猜测题。由第一段和第三段可知大多数人因害怕不想见到灰护士鲨,但是Shalise Leesfield认为灰护士鲨是最可爱的动物,所以她不是害怕灰护士鲨的人,由此推知,them指代“害怕灰护士鲨的人”。故选C项。 2.D　细节理解题。由第五段第二、三句“But fishers are allowed access within 200 meters of Fish Rock. This is leading to a drop in the number of gray nurse sharks and is increasing pollution, says Leesfield.”可知,渔民可以进入距离鱼岩200米以内的区域。这导致灰护士鲨的数量下降,污染加剧。故选D项。 3.D　细节理解题。由最后一段可知,Leesfield和Faehrmann通过法律保护鱼岩附近的禁渔区。故选D项。 4.A　主旨大意题。通读全文可知,本文讲述澳大利亚少年Shalise Leesfield致力于保护灰护士鲨的故事,A项“这名澳大利亚少年正在执行保护灰护士鲨的任务”最适合作为文章标题。故选A项。 Ⅱ.语篇解读　本文是一篇说明文。文章不仅指出旅行具有不可否认的魅力,还从打破常规、与人联结、提升自信、活在当下四个维度,深入剖析了旅行让人感到幸福的深层缘由。 【高频词汇】　1.light up照亮;变亮　2.commitment n.承诺　3.relieve v.缓解;减轻　4.boost v.促进;增强 5.break free from摆脱　6.figure out弄清楚 7.resourceful adj.足智多谋的　8.adaptable adj.能适应的 【熟词生义】　fuel熟义:n.燃料　生义:v.增加;加强;刺激 1.D　前文提到旅行中充满魔力,能点亮心灵,后文则转折指出“它不只是风景变化或逃离日常生活的机会——尽管那些有帮助!”,并引出“探索旅行带来快乐的深层原因”的话题。由此可知,设空处需要一个承上启下的句子,既承接前文“旅行带来快乐”的现象,又引发后文对其背后深层原因的探讨。D项“但你是否曾好奇,它为什么能让你如此快乐?”符合语境。 易错归因 　　本题易错选C项“旅行让你接触新的风景、声音和文化”。该项描述的是旅行的具体体验,而非引发对其背后深层原因的思考,与后文“探索深层原因”的衔接不紧密,无法起到承上启下的作用,故排除。 2.F　前文指出“生活有时像永无止境的责任循环——工作、家务和承诺”,后文则提到“那种自由能激发放松感和冒险精神,缓解压力、改善你的情绪”。由此可见,设空处需体现旅行带来自由,衔接“责任压力”与“自由放松”。F项“旅行能让你逃到一个没有截止日期和闹钟的世界”符合语境。 3.G　根据上文的“Travel brings you closer to people”以及下文的“Human connection is a fundamental source of happiness”可知,设空处需进一步说明“旅行带来的人际联结”的意义,衔接“建立联结”与“联结带来快乐”。G项“这些联结往往会催生难忘的故事和珍贵的回忆”符合语境。 4.E　前文提到“踏入陌生的地方可能令人沮丧,但每次新旅行都会让你更加相信自己应对未知的能力——无论是搞清楚新地铁系统,还是克服语言问题,旅行都要求你变得足智多谋并有适应能力”,可见设空处需延续“旅行挑战→能力提升→信心增长”的逻辑,强调“克服挑战”与“信心”的关联。E项“而且每克服一个挑战,你的信心就会增长”符合语境。 5.A　根据空后内容可知,旅游时,你很难想到其他事情,并且当下时刻的这种专注状态是促成幸福感的重要因素。A项“旅行能让你专注当下”直接点明段落主旨。 Ⅲ.语篇解读　本文是一篇记叙文。文章主要讲述了一只名为Clark的秃鹰的出身背景、生活现状以及它如何参与公共教育活动,提升人们保护野生动物的意识的故事。 【高频词汇】　1.frequent adj.频繁的　2.announce sth. to sb.向某人宣布某事　3.breeding n.繁殖　4.lasting adj.持久的　5.impression n.印象 【熟词生义】　father熟义:n.父亲　生义:v.成为……的父亲 1.C　考查名词辨析。根据上文“When the plane touches down”和下文“will often announce to the cabin”可知,此处应是指飞机上的工作人员向乘客宣布信息,最合适的人是飞行员。故选C。 2.B　考查动词辨析。根据上文“When the plane touches down”可知,此处表示“着陆”。故选B。 3.A　考查名词辨析。根据下文“to the United States in 1982 by West Germany”及历史背景和外交常识可知,动物作为两国友谊的象征通常被当作礼物赠送。故选A。 4.B　考查形容词辨析。根据上文“At the time, the bald eagle was endangered, and environmentalists were”可知,由于秃鹰濒危,所以美国收到这样的礼物时,环保主义者可能担忧其保护现状。故选B。 5.D　考查动词辨析。根据下文“The species was saved and it was 　7　 from the list of threatened species in 2007.”可知,此处指针对濒危物种的保护工作,目的是恢复种群数量。故选D。  6.A　考查形容词辨析。根据下文“The species was saved and it was 　7　 from the list of threatened species in 2007.”可知,该物种被拯救,由此可知结果是令人满意的。故选A。  7.C　考查动词辨析。根据上文“The species was saved”和下文“from the list of threatened species in 2007”可知,此处指秃鹰因为数量恢复,不再属于濒危物种,所以被从濒危物种名单上移除。故选C。 8.B　考查动词辨析。根据下文“six healthy eaglets(雏鹰)”可知,Captain作为一只雄性秃鹰参与繁殖计划,成为六只健康雏鹰的父亲。故选B。 9.D　考查动词辨析。根据上文“While Clark's siblings were”和下文“into the wild, Clark has spent his whole life under human care”可知,此处对比了Clark和其兄弟姐妹的状况,Clark一生都在人类的照料下度过,而它的兄弟姐妹被放归野外。故选D。 10.D　考查副词辨析。根据上文“Clark's claw(爪) did not form”可知,此处指Clark有生理缺陷,爪子没有正常发育。故选D。 11.A　考查名词辨析。根据上文“Clark's claw(爪) did not form 　10　 and just didn't give him”和下文“that he would need”可知,此处指Clark因为生理缺陷,无法拥有在野外生存所必需的能力。故选A。  12.B　考查形容词辨析。根据语境可知,野外环境恶劣,对于有生理缺陷的生物来说,不是一个宽容的环境。故选B。 13.D　考查动词辨析。根据下文“flight demonstrations and other educational programs at events”可知,Clark参与的是教育展示活动,因此是进行飞行表演。故选D。 14.A　考查动词短语辨析。根据下文“Clark's physical presence leaves a lasting impression”可知,Clark的现身给人们留下了持久的印象,blow sb. away意为“给某人留下深刻印象”。故选A。 15.A　考查动词辨析。根据上文“Clark travels across the country to 　13　 flight demonstrations and other educational programs at events.”和下文“people to care more about conservation efforts”可知,Clark的现身给人们留下了持久的印象并鼓励人们更加关注保护工作。故选A。  1 学科网（北京）股份有限公司 $
