The Amazon River, 3 brings the name to the rainforest, is close to 6,400 kilometres in 4 (long) — roughly 100 kilometres longer than the Yangtze River. Providing food and shelter for an unbelievable 5 (vary) of wildlife, the Amazon rainforest is the natural domain of more than 1,300 species of birds and over 400 species of mammals 6 ( hide) among the Amazon rainforest’s plant life. The Amazon rainforest is a treasure house of species that can be used for food 7 medicine. Over the past 50 years, about 17 percent of the rainforest 8 (destroy) due to human activities. As the impact of human activities 9 (continue) to grow and the list of species in danger of extinction becomes longer, we are left with a question: can we have an urge 10 (suspend) the damage to the “lungs of the planet”? 五、阅读理解 （重庆市2024-2025学年高三上学期・阶段练习）An ancient diamond found in Botswana contains a never- before- seen mineral that came from deep inside Earth. The mineral — named davemaoite — provides a unique window into deep- Earth chemistry. Originally dug up in a mine in Orapa, Botswana, the diamond is about 4 millimetres wide and weighs 81 milligrams. A dealer sold it in 1987 to a scientist, but neither the dealer nor the scientist had any idea how special it was. The diamond was more recently analysed by Oliver Tschauner at the University of Nevada. Most diamonds form 120 to 250 kilometres underground. Tschauner and his colleagues realised that the Botswanan diamond was from the lower mantle (地幔), which begins 660 kilometres below the surface. After examining it using X-rays, they discovered tiny crystal s of another mineral trapped inside. The crystals turned out to be a form of calcium silicate that was theorised to exist in the lower mantle but had never actually been observed before. They named the new calcium silicate mineral davemaoite in honour of deep- Earth scientist Ho-Kwang “Dave” Mao. Normally, davemaoite’s crystal structure would break apart if it was brought up to Earth’s surface because of the massive drop in pressure. But because it was trapped inside a diamond, it was preserved on its long journey up to the Orapa mine. “When we broke open the diamond, the davemaoite stayed intact for about a second, and then we saw it expand under the microscope and basically turn into glass,” says Tschauner. The molecules within it take on a particular cubic arrangement known as a perovskite structure. This structure shows it could only have formed under the extreme conditions experienced in the lower mantle, where the pressure is more than 200,000 times that found at Earth’s surface. Davemaoite is thought to make up about 5 per cent of Earth’s lower mantle, and is important because it can also host radioactive elements like uranium, thorium and potassium-40 that heat Earth as they decay. Without these radioactive elements, the Earth would have cooled by now. 1．What do we know about the mineral davemaoite? A．It was named in memory of a great politician. B．It was discovered as soon as the diamond was found. C．It had never actually been found before the discovery. D．It had been stuck in a diamond 200 kilometres underground. 2．What does the underlined word “intact” in Paragraph 4 mean? A．Divided. B．Overlooked. C．Hidden. D．Undamaged. 3．Why is the mineral davemaoite significant? A．Because it has a cooling effect. B．Because its internal structure is special. C．Because it contains heat- producing elements. D．Because its formation background is extreme. 4．What is the purpose of the text? A．To explain the uses of a substance. B．To introduce the discovery of a mineral. C．To stress the role of deep- Earth chemistry. D．To advocate the protection of radioactive elements. 六、七选五 （江苏省南通市 2023-2024 学年高二下学期・阶段练习）The world is a vast and beautiful place, full of natural wonders and man-made marvels.

C．To stress the role of deep- Earth chemistry. D．To advocate the protection of radioactive elements. 【答案】1．C 2．D 3．C 4．B 【导语】这是一篇说明文。文章主要介绍了一种名为davemaoite的新矿物的发现及其重要性。 1．细节理解题。根据文章第三段的“The crystals turned out to be a form of calcium silicate that was theorised to exist in the lower mantle but had never actually been observed before.(这些晶体原来是硅酸钙的一种形式，理论上存在于下地幔中，但以前从未被观测到)”可知，在这次发现之前，davemaoite这种矿物实际上从未被发现过。故选C。 2．词句猜测题。根据上文“Normally, davemaoite’s crystal structure would break apart if it was brought up to Earth’s surface because of the massive drop in pressure. But because it was trapped inside a diamond, it was preserved on its long journey up to the Orapa mine.(通常情况下，如果由于压力的大幅下降而被带到地球表面，davemaoite晶体结构会破裂。但由于它被困在一颗钻石中，在通往奥拉帕矿的漫长旅程中被保存了下来)”和后文“and then we saw it expand under the microscope and basically turn into glass(然后我们看到它在显微镜下膨胀，基本上变成了玻璃)”可知，当我们打开钻石时，davemaoite晶体在不被损害的情况下保持约一秒钟，然后我们看到它在显微镜下膨胀，基本上变成了玻璃。所以划线单词intact 意为“完好无损的，未被损坏的”，与Undamaged意思一致。故选D。 3．细节理解题。根据文章最后一段“Davemaoite is thought to make up about 5 per cent of Earth’s lower mantle, and is important because it can also host radioactive elements like uranium, thorium and potassium-40 that heat Earth as they decay. Without these radioactive elements, the Earth would have cooled by now.(Davemaoite被认为约占地球下地幔的5%，它很重要，因为它还可以容纳铀、钍和钾-40等放射性元素，这些元素在衰变时会加热地球。如果没有这些放射性元素，地球现在应该已经冷却了)”可知，Davemaoite还可以容纳铀、钍和钾-40 等放射性元素，这些元素在衰变时会加热地球。所以它的重要性在于含有产生热量的放射性元素。故选C。 4．推理判断题。根据第一段的“An ancient diamond found in Botswana contains a never- before- seen mineral that came from deep inside Earth. The mineral — named davemaoite — provides a unique window into deep- Earth chemistry.  Originally dug up in a mine in Orapa, Botswana, the diamond is about 4 millimetres wide.(在博茨瓦纳发现的一颗古老的钻石中含有一种前所未见的矿物，这种矿物来自地球深处。这种矿物被命名为davemaoite，它为研究地球深部的化学成分提供了一个独特的窗口。这颗钻石最初是在博茨瓦纳的奥拉帕矿中挖掘出来的，直径约4毫米)”可推知， 本篇文章的目的是介绍了一种新发现的矿物davemaoite。故选B 六、七选五 （江苏省南通市 2023-2024 学年高二下学期・阶段练习）The world is a vast and beautiful place, full of natural wonders and man-made marvels.

F．The more you know, the better you do in the preservation. G．But these places are not just important for our own enjoyment. 【答案】1．G 2．A 3．D 4．F 5．E 【导语】本文是一篇议论文。文章探讨了世界上的自然和文化遗产对于我们的重要意义，指出它们很多都面临着危险，呼吁我们采取行动，共同努力，保护这些惊人的遗址。 1．前文“From the ancient ruins of Rome to the Great Wall of China, there are countless places that make us proud of our ancestors. (从罗马的古代遗址到中国的长城，有无数的地方让我们为我们的祖先感到骄傲)”提到这些奇迹让当代人为之骄傲，后文“They are also essential for future generations. (它们对后代也至关重要)”提到它们对后代的重要性，因此G项“But these places are not just important for our own enjoyment. (但这些地方不仅对我们自己的享受很重要)”符合语境，指出这些地方的意义不仅仅是针对当代人，和前文构成转折，引出后文。故选G。 2．前文“Heritage can inspire us. (遗产可以激励我们)”提到遗产对人的激励作用，因此A项“It can give us hope for the future. (它能给我们未来的希望)”符合语境，指出它让人对未来充满希望，承接前文，且符合本段每两句介绍遗产的一项意义的行文逻辑。故选A。 3．后文“The Great Barrier Reef is the world’s largest coral reef system, and it is at risk from natural forces, including climate change and pollution. The Amazon rainforest is the world’s largest tropical rainforest, regulating the Earth’s climate. It is at risk from human activities, like deforestation, mining, and agriculture. (大堡礁是世界上最大的珊瑚礁系统，它正面临着自然力量的威胁，包括气候变化和污染。亚马逊雨林是世界上最大的热带雨林，调节着地球的气候。它受到人类活动的威胁，如砍伐森林、采矿和农业)”具体介绍了大堡礁和亚马逊雨林正受到破坏，因此D项“Unfortunately, many of them are under threat. (不幸的是，它们中的许多地方正受到威胁)”符合语境，指出很多地方正受到威胁，可作为段首句统领后文内容，其中的under threat和后文的at risk呼应。故选D。 4．前文“Learn more about the sites that are on the List of World Heritage in Danger. (了解更多关于世界濒危遗产名录的信息)”建议了解世界濒危遗产名录，因此F项“The more you know, the better you do in the preservation. (你了解的越多，你在保护方面做得就越好)”符合语境，指出这样做的好处，承接前文。故选F。 5．前文“Together, we can make a difference. (只要我们齐心协力，我们就能有所作为)”指出齐心协力可以带来不同，因此E项“Let’s work together to preserve these incredible sites. (让我们共同努力，保护这些惊人的遗址)”符合语境，倡议一同保护这些遗址，承接前文。故选E。 七、完形填空 （福建省南平市 2021-2022 学年高二上学期・阶段练习）One girl is being praised for a letter of apology she wrote to the rangers (园林管理员) at the National Parks Service (NPS).
