5G changes the world, creates the future
It is reported that the commercialization of 5G in China is expected to produce a direct economic output of 10.6 trillion yuan (US $1.5 trillion) from 2020 to 2025, plus an indirect economic output of about 24.8 trillion yuan, while directly creating more than 3 million jobs.
Besides profits and job creation, 5G is making other changes in the world.
★No need to meet a doctor in person
Traveling between different cities just to find a better doctor is often time-consuming. With 5G, we could achieve a remote diagnosis and even real-time operations.
The high-level standard for hospital 5G radio access networks is required. The average downlink throughput should be 450 Mbps while the uplink should be 50 Mbps. The average Round-Trip Time (RTT) delay between a medical terminal (终端) and a local medical application platform should be 20ms or below.
★The city with a brain
The “brain of city safety,” otherwise known as the smart city, developed by 360 Total Security, provides another way of dealing with city safety issues.
A highly automatic computerized network, driven by big data, the Internet of Things (IoT) and 5G, has been used to predict or detect emergency cases around the city.
Zhao Weiting, an expert at Smart City Solutions said that the smart city system has changed the way that emergency cases are dealt with.
“In the past, when an emergency case happened, all we could do was deal with it afterward,” said Zhao, “but now the smart brain can collect a large amount of data and analyze it. From this, we can predict a potential case based on abnormal patterns detected by the system and send them to safety departments to make a final decision.”
According to Zhao, the smart city system has already been deployed in the city of Chongqing and Tianjin, and is planned in more cities in the coming years.
★Taking over life-threatening jobs
China Telecom presented its remote control vehicle at an exhibition. The vehicle, hundreds of miles away in Nanjing, gives a real-time reaction based on the signal sent from the simulator (模拟器) in the Beijing International Convention Center. The real-time feedback from the simulator and the live images transmitted from the cameras installed (安装) on the vehicle make it hard to differentiate from a real driving experience.
Such technology could be used in dangerous situations, such as oil drilling (钻探), fire-fighting, or any other emergency response job that could be life-threatening to people on the ground.

5G 改变世界，创造未来
据报道，2020 年至 2025 年期间，中国 5G 商业化预计将直接产生 10.6 万亿元（1.5 万亿美元）的经济产出，间接经济产出约 24.8 万亿元，同时直接创造超过 300 万个就业岗位。
除了盈利和创造就业机会，5G 还在世界范围内引发其他变化。
★无需亲自看医生
为了找更好的医生而在不同城市之间奔波往往耗时费力。有了 5G，我们就能实现远程诊断，甚至实时手术。
医院 5G 无线接入网络的高标准要求平均下行吞吐量达到 450Mbps，上行吞吐量达到 50Mbps。医疗终端与本地医疗应用平台之间的平均往返时间（RTT）延迟应在 20 毫秒或以下。
★有“大脑”的城市
由 360 安全卫士开发的“城市安全大脑”，即智慧城市，为解决城市安全问题提供了另一种途径。一个由大数据、物联网和 5G 驱动的高度自动化的计算机网络已被用于预测或检测城市周边的紧急情况。
智慧城市解决方案专家赵伟廷表示，智慧城市系统改变了处理紧急情况的方式。
赵伟廷说：“过去，当紧急情况发生时，我们只能事后处理，但现在智能大脑可以收集大量数据并进行分析。通过这种方式，我们可以根据系统检测到的异常模式预测潜在的紧急情况，并将其发送给安全部门做出最终决定。”
据赵伟廷介绍，智慧城市系统已经在重庆和天津部署，并计划在未来几年在更多城市推广。
★接管危险工作
中国电信在一次展览会上展示了其远程控制车辆。该车辆位于数百英里外的南京，根据北京国际会议中心模拟器发出的信号做出实时反应。模拟器提供的实时反馈以及安装在车辆上的摄像头传输的实时图像，让人难以区分这与真实的驾驶体验有何不同。
这种技术可用于危险情境，比如石油钻探、灭火或任何其他可能危及地面人员生命的紧急救援工作。

综合实战演练
Passage 1
Water is life. It is the source of any possibility for growth and liveliness. That is why water waste is such a big concern in places where water is insufficient. But that’s where Direct Potable Reuse, also known as DPR, can help.
DPR is a method for taking waste water and turning it into drinking water, according to Wastewater Digest. Though the sound of it may make people feel sick, it has been used with great success and to no ill-effect in Namibia for over fifty years.
Namibia is the driest country in sub-Saharan Africa. Its capital, Windhoek, is in the middle of two of the oldest deserts in the world, and is 400 miles away from the nearest river. And yet, over 400 thousand people live in Windhoek, and thanks to a clever method of water reuse, nearly every one of them has access to clean drinking water.
Windhoek built its first water-recycling plant in 1968, leading the area to be referred to as the “birthplace of water-recycling”. According to Positive News reports, in the recycling plant, the wastewater goes through an multi-barrier process which removes pollutants and bacteria in the water. This is similar to how water is filtered (过滤) in nature. The water-recycling plant, however, has an expedited handling procedure. It produces safe drinking water within twenty four hours.
Though Namibia has been successfully using DPR for half a century, it has been slower to catch on in other parts of the world. The greatest roadblock so far has been public opinion. Patty Tennyson, the Vice President of Katz and Associates told Positive News, “Technology has never been the reason why these projects don’t get built — it’s always public or political opposition.”
The time for overcaution (过分谨慎) has passed though. As temperatures increase and the world gets thirstier, this safe and efficient water-saving technology can not be ignored. The success of DPR in Namibia has shown that a little creativity can make even the desert produce flowers.
1．Why does the author mention the position of Windhoek in paragraph 3
A．To present the locals’ poor situation. B．To show the significance of DPR.
C．To describe the scenes of the city. D．To help tourists locate the capital.
2．Which of the following is closet in meaning to the underlined word “expedited” in paragraph 4
A．Safer. B．Similar. C．Faster. D．Premier.
3．What can be inferred about the future of DPR
A．It will be replaced by new technology. B．It will only be used in desert regions.
C．It will be more acceptable in the world. D．It will be ignored in developed countries.
4．What is the best title of the text
A．DPR, a method making a different world B．Water shortage, a big concern in the world
C．Windhoek, the birthplace of water-recycling D．DPR, a technology making people feel sick
【答案】1．B 2．C 3．C 4．A
【导语】本文是一篇说明文。主要介绍直接饮用水再利用技术（DPR）及其在纳米比亚的应用和推广前景。
1．推理判断题。根据第三段“Namibia is the driest country in sub-Saharan Africa. Its capital, Windhoek, is in the middle of two of the oldest deserts in the world, and is 400 miles away from the nearest river. And yet, over 400 thousand people live in Windhoek, and thanks to a clever method of water reuse, nearly every one of them has access to clean drinking water.(纳米比亚是撒哈拉以南非洲最干旱的国家。其首都温得和克位于世界上最古老的两个沙漠中间，距离最近的河流有400英里。然而，超过40万人居住在温得和克，多亏了一种巧妙的水再利用方法，几乎每个人都能获得干净的饮用水)”可推知，作者提及温得和克的位置，是为了凸显其缺水的地理环境，从而体现DPR技术在此地的重要意义。故选B项。
2．词句猜测题。根据第四段中的“This is similar to how water is filtered (过滤) in nature. The water-recycling plant, however, has an expedited handling procedure. It produces safe drinking water within twenty four hours.(这类似于自然界中水的过滤方式。然而，这家水循环工厂有一个expedited处理程序。它能在24小时内生产出安全的饮用水)”可知，与自然界的过滤相比，该工厂的处理程序能在24小时内产出安全饮用水，说明其过程更快，因此“expedited”意为“更快的”。故选C项。
3．推理判断题。根据第五段中的“Though Namibia has been successfully using DPR for half a century, it has been slower to catch on in other parts of the world. The greatest roadblock so far has been public opinion.(尽管纳米比亚成功使用DPR已有半个世纪，但在世界其他地区，它的普及速度较慢。到目前为止，最大的障碍是公众舆论)”以及第六段中的“As temperatures increase and the world gets thirstier, this safe and efficient water-saving technology can not be ignored.(随着气温升高，世界变得更加干旱，这种安全高效的节水技术不容忽视)”可推断，随着全球缺水问题加剧，DPR技术将在世界范围内更易被接受。故选C项。
4．主旨大意题。通读全文，尤其是第一段中的“But that’s where Direct Potable Reuse, also known as DPR, can help.(但这正是直接饮用水再利用（DPR）所能提供帮助的地方)”和最后一段中的“The success of DPR in Namibia has shown that a little creativity can make even the desert produce flowers.(DPR在纳米比亚的成功表明，一点创造力甚至可以让沙漠开花)”可知，文章主要介绍了DPR技术及其带来的积极影响，A选项“DPR，一种改变世界的方法”最能概括全文主旨，是文章的最佳标题。故选A项。
Passage 2
Glass might soon meet a surprising competitor: bamboo. Scientists in China have transformed regular bamboo into a see-through material that keeps out fire and water and reduces smoke, providing an environmentally friendly replacement for traditional glass made from sand. While glass is still widely used in buildings for its clearness, its tendency to break easily, heavy weight and environmental impact have pushed researchers to look for other materials like clear wood — and now bamboo.
Clear wood, made by removing a natural substance called lignin (木质素) and adding plastic-like materials, has been seen as a good renewable option. It is lighter than glass and better at keeping heat out. However, its tendency to catch fire and the slow growth rate of trees make it hard to produce in large amounts: To solve this, researchers at Central South University of Forestry and Technology focused on bamboo, which grows fully in 4-7 years and produces four times more material per farm area compared to trees.
The team applied the methods developed for making wood see-through to bamboo, which has a similar chemical makeup. Specifically, by removing linger, which makes plants look solid, and filling the bamboo fibers with a glass-like liquid called sodium silicate, they changed how light passes through the material, achieving 71.6% clearness. A final water-blocking treatment created three layers: a protective outer coating, a middle layer of silicon dioxide (a common glass ingredient), and a base layer of sodium silicate. The final material showed impressive strength, outshining many common plastics.
Importantly, the clear bamboo showed special fire safety features. Unlike wood-based materials, it didn’t catch fire easily, blocked water, and stopped dangerous smoke and gases from spreading — key benefits for building use. When tested as a base for advanced solar cells, it helped control light better, increasing energy production by 15.29%. This double role suggests it could be used in smart buildings that use sunlight for lighting while creating clean energy. While making this material in large amounts still needs work, this discovery supports environmental goals.
5．Which of the following is one of the reasons for researchers to replace the current widely used glass
A．It’s not clear enough. B．It harms the environment.
C．Its cost is too high. D．It catches fair easily.
6．What features of bamboo makes it a suitable choice for making clear glass
A．Its lighter weight. B．Its clearness. C．Its tall height. D．Its high yield.
7．What does paragraph 3 mainly talk about
A．The production process of the new material.
B．The superb advantages of the new material.
C．The outstanding features of bamboo.
D．The biological construction of bamboo.
8．What can be inferred about the clear bamboo from the last paragraph
A．It has a bright future in smart buildings.
B．It has been produced in large amounts.
C．It may serve as a kind of clean energy.
D．It can clear off the poisonous smoke.
【答案】5．B 6．D 7．A 8．A
【导语】本文是一篇说明文。文章主要介绍了中国科学家研发的一种透明竹材料，该材料具有防火防水、减少烟雾等特性，有望成为传统玻璃的环保替代品。
5．细节理解题。根据第一段“While glass is still widely used in buildings for its clearness, its tendency to break easily, heavy weight and environmental impact have pushed researchers to look for other materials like clear wood — and now bamboo. (虽然玻璃因其清洁性仍被广泛用于建筑中，但它容易破碎、重量大以及对环境的影响促使研究人员寻找其他材料，比如透明木材——现在是竹子。)”可知，传统玻璃存在易碎、重量大和环境危害等问题。故选B。
6．细节理解题。根据第二段“To solve this, researchers at Central South University of Forestry and Technology focused on bamboo, which grows fully in 4-7 years and produces four times more material per farm area compared to trees. (为了解决这个问题，中南林业科技大学的研究人员把重点放在竹子上，竹子在4-7年内生长完全，每个农场生产的材料是树木的四倍。)”可知，竹子生长周期短且单位面积产量高，所以适合作为制作透明玻璃的理想材料。故选D。
7．主旨大意题。根据第三段“Specifically, by removing linger, which makes plants look solid, and filling the bamboo fibers with a glass-like liquid called sodium silicate, they changed how light passes through the material, achieving 71.6% clearness. A final water-blocking treatment created three layers: a protective outer coating, a middle layer of silicon dioxide (a common glass ingredient), and a base layer of sodium silicate. (具体来说，通过去除使植物看起来坚硬的黏液，并在竹纤维中填充一种叫做硅酸钠的玻璃状液体，他们改变了光线通过材料的方式，达到了71.6%的清晰度。最后的阻水处理形成了三层：外层保护层、中间层二氧化硅（一种常见的玻璃成分）和底层硅酸钠。)”可推知，本段主要介绍了透明竹材的制作过程。故选A。
8．推理判断题。根据最后一段“This double role suggests it could be used in smart buildings that use sunlight for lighting while creating clean energy. (这种双重作用表明，它可以用于智能建筑，在使用阳光照明的同时创造清洁能源。)”可推知，透明竹材在智能建筑中具有应用潜力。故选A。
Passage 3
Scientists in Australia are testing printed solar panels to power a Tesla on a 15,100-kilometer (9,400-mile) journey beginning in September, which they hope will get the public thinking about steps to help prevent climate change.
The Charge Around Australia (CAA) project will power a Tesla electric car with 18 of the team’s printed plastic solar panels, each 18 meters (59 feet) long, rolling them out beside the vehicle to absorb sunlight when it needs a charge.
Paul Dastoor. the inventor of the printed solar panels, said the University of Newcastle team would be testing not only the endurance of the panels but their potential performance for other applications. “This is actually an ideal test bed to give us information about how we would go about using and powering technology in other remote locations, for example, in space,” Dastoor told Reuters in the town of Gosforth, north of Sydney.
Printed solar is a lightweight, laminated (层压的) plastic that can be made at a cost of less than $10 a square meter. The panels are made on a commercial printer originally used for printing wine labels.
Dastoor said using the panels to power a car would get Australians to think more about electric vehicles and could help ease their “range anxiety.” The community is seeking these sorts of answers to the problems it’s being faced with, day in, day out, around climate change.
On their 84-day Tesla journey, the team plans to visit about 70 schools to give students a taste of what the future may hold. Asked what Elon Musk, creator of the Tesla car and founder of Tesla Inc TSLA．O, might say about the CAA project, Dastoor said he hoped he would be pleased. CAA was “showing how our innovative technology is now combining with his developments to develop new solutions for the planet”, Dastoor said.
9．What can we learn about the printed solar panel
A．It weighs a lot. B．It can be rolled and carried.
C．It can be used at any time of a day. D．It has been applied to power gas cars.
10．What is “range anxiety” in Paragraph 5 probably about
A．The climate is getting worse. B．The solar panels are 100 long.
C．The solar panels are expensive. D．The endurance of the panels is poor.
11．What can be inferred from the last paragraph
A．Musk is pleased with the CAA project.
B．Students are positive about their own future.
C．The electric car lasts 84 days on a single charge.
D．The CCA team and Musk are making efforts for climate changes.
【答案】9．B 10．D 11．D
【导语】本文是一篇说明文。文章介绍了澳大利亚科学家测试印刷太阳能电池板为特斯拉汽车供电的项目，该项目旨在引发公众对防止气候变化的思考，还介绍了电池板特点及项目相关计划。
9．细节理解题。根据第二段“The Charge Around Australia (CAA) project will power a Tesla electric car with 18 of the team’s printed plastic solar panels, each 18 meters (59 feet) long, rolling them out beside the vehicle to absorb sunlight when it needs a charge.(澳大利亚充电之旅(CAA)项目将用该团队的18块印刷塑料太阳能电池板为一辆特斯拉电动汽车供电，每块电池板长18米(59英尺)，当汽车需要充电时，展开它们，铺在车旁以吸收阳光)”可知，这种印刷太阳能电池板可以卷起来携带。故选B项。
10．词句猜测题。根据第五段中“Dastoor said using the panels to power a car would get Australians to think more about electric vehicles and could help ease their ‘range anxiety.’(达斯托尔说，使用这些电池板为汽车供电将让澳大利亚人更多地考虑电动汽车，并有助于缓解他们的‘续航焦虑’)”可知，新的印刷太阳能电池板将让澳大利亚人更多地考虑电动汽车，说明这种电池板缓解了之前的担忧。结合选项可推知，“range anxiety”指的是对“电池板的续航能力差”的焦虑。故选D项。
11．推理判断题。根据最后一段中“CAA was ‘showing how our innovative technology is now combining with his developments to develop new solutions for the planet’, Dastoor said.(达斯托尔说，澳大利亚充电之旅项目‘展示了我们的创新技术如何与他(马斯克)的发展相结合，为地球开发新的解决方案’)”和常识可知，太阳能电池板项目有助于节能减排，是应对地球气候变化的可行解决方案，所以CAA团队和马斯克都在为应对地球气候变化而努力。故选D项。
Passage 4
When Dr. Emily Carter was a young girl, she was fascinated by the way water interacted with different materials in her backyard. She would spend hours watching how rainwater passed through the soil, and how certain plants seemed to grow better in wet. This early curiosity about the natural world’s processes stayed with her as she grew older.
After obtaining degrees in environmental science and materials engineering, Dr. Carter started to think about how to use her knowledge to address a growing problem: water pollution in urban areas. Stormwater runoff, which picks up pollutants like oil, chemicals, and debris from roads and parking lots, was a major contributor to the worse of local water bodies.
She decided to design a new pavement material that could act as a natural filter (过滤器). Her idea was to create a porous (多孔的) concrete that would allow rainwater to pass through while trapping pollutants. Through countless experiments with different aggregates (骨料), binders, and additives, and by studying the behavior of various microorganisms that could potentially break down the trapped pollutants, Dr. Carter constructed small-scale test areas in her city. These areas were equipped with sensors to monitor the flow of water and the levels of pollutants both before and after passing through the new pavement.
As the months passed, The results were remarkable. The pavement significantly reduced pollutants in stormwater runoff. Encouraged by the results, Dr. Carter cooperated with local companies and agencies, aiming to build a city-wide network of pollutant-filtering pavements. Her vision was to give cities a self-cleaning mechanism, using nature’s purification processes to solve environmental problems.
12．What can we learn about Dr. Emily Carter from the first two paragraphs
A．She was interested in urban development.
B．She had a strong desire to study engineering.
C．Her dream was to become a famous scientist.
D．Her childhood curiosity contributed to her later design.
13．Why did Dr. Carter decide to design a new pavement material
A．To deal with water pollution in cities. B．To promote the growth of urban plants.
C．To reduce the cost of road construction. D．To improve the condition of urban roads.
14．What was the key to Dr. Carter's pavement design
A．Installing advanced sensors. B．Using high-quality concrete.
C．Trapping and breaking down pollutants. D．Cooperating with construction companies.

Passage 5
The legendary dire wolf—a well-known creature that disappeared around 13,000 years ago and gained fame through HBO’s TV series Game of Thrones—has made an extraordinary return. This is the result of a cutting-edge genetic project by the company Colossal Biosciences, marking the first-ever successful “de-extinction” of a species.
Recently, the company revealed the birth of three healthy dire wolf babies. Their arrival was made possible by combining DNA from ancient dire wolf fossils with the genes of their closest living relative, the grey wolf. To achieve this, scientists used a cloning technique called somatic cell nuclear transfer. They took DNA from a 13,000-year-old tooth and a 72,000-year-old bone, inserted the cell nuclei (体细胞核) into donor egg cells to create embryos (胚胎), and then implanted these embryos into a domestic dog mother, who gave birth in January. Ben Lamm, CEO of Colossal, expressed his excitement, saying, “any sufficiently advanced technology is similar to magic”.
The dire wolf was once a fierce top predator across North America in Ice Age. They preyed on large mammals like horses, bison and potentially mammoths, but after these species went extinct, the dire wolf’s rule also came to an end. According to paleontologist (古生物学家) Julie Meachen, with the loss of their prey, the dire wolf was gradually replaced by the grey wolf.
Dire wolves were larger and stronger than their modern grey relatives, with jaws and shoulders built for powerful hunts. Their revival has attracted both science enthusiasts and pop culture fans alike.
Dr. Christopher Mason, a scientific adviser for Colossal, described the de-extinction of the dire wolf as a transformative leap in genetic engineering. “This is an extraordinary technological leap for both science and conservation,” he stated. “It’s a wonderful example of the power of biotechnology to protect species, both existing and extinct.”
16．How were the dire wolf babies created
A．By combining genes of a grey wolf and a domestic dog.
B．By using a method called somatic cell nuclear transfer.
C．By changing the behavior of modern wolves.
D．By natural reproduction in a lab setting.
17．What caused the dire wolf’s extinction around 13,000 years ago
A．Lack of food. B．Climate change.
C．Human hunting. D．Wolf competition.
18．What’s Dr. Christopher Mason’s view on de-extinction
A．It is a biological experiment with little practical value.
B．It can only be used on species that recently went extinct.
C．It shows biotechnology’s potential to protect and revive species.
D．It has attracted both science enthusiasts and pop culture fans alike.
19．Which of the following would be the best title for the article
A．A TV Series Inspires New Wolf Species Research
B．Scientists Clone Grey Wolves for Species Conservation
C．Dire Wolves Return: Breakthrough in De-Extinction Technology
D．The Predator in Ice Age: the Extraordinary Story of the Dire Wolf
【答案】16．B 17．A 18．C 19．C

Ben Lamm, CEO of Colossal, expressed his excitement, saying, “any sufficiently advanced technology is similar to magic”. (为了实现这一目标，科学家们使用了一种称为体细胞核转移的克隆技术。他们从一颗13000年前的牙齿和一块72000年前的骨头中提取DNA，将细胞核植入供体卵细胞中，然后将这些胚胎植入一只家犬母亲体内，后者于今年1月产下幼犬。Colossal的首席执行官Ben Lamm表达了他的兴奋之情，他说：“任何足够先进的技术都类似于魔法。”)”可知，恐狼幼崽是通过体细胞核移植技术培育的。故选B。
17．细节理解题。根据第三段中“They preyed on large mammals like horses, bison and potentially mammoths, but after these species went extinct, the dire wolf’s rule also came to an end. (它们以马、野牛甚至猛犸象等大型哺乳动物为食，但随着这些物种的灭绝，恐狼的统治也宣告终结)”可知，大型猎物灭绝导致恐狼食物短缺，最终走向灭绝。故选A。
18．推理判断题。根据第五段“Dr. Christopher Mason, a scientific adviser for Colossal, described the de-extinction of the dire wolf as a transformative leap in genetic engineering. “This is an extraordinary technological leap for both science and conservation,” he stated. “It’s a wonderful example of the power of biotechnology to protect species, both existing and extinct.” (Colossal公司的科学顾问克里斯托弗 梅森(Christopher Mason) 博士将恐狼的复活描述为基因工程的一次变革性飞跃。他说：“这对科学和环保来说都是一次非凡的技术飞跃。”“这是生物技术保护物种的一个很好的例子，无论是现存的还是灭绝的。”)”可知，他认为基因复活技术体现了生物技术保护物种的潜力。故选C。

Passage 6
Known for its role in Game of Thrones (《权力的游戏》), the dire wolf (冰原狼) went extinct over 10,000 years ago. On April 7, the US company Colossal Biosciences announced restoring this species via de-extinction — a historic first.
Time magazine said scientists studied fossils (化石) such as a 13,000-year-old dire wolf tooth and a 72,000-year-old ear bone and compared their genes to those of gray wolves to discover differences. They edited 14 key genes in gray wolf blood cells to match dire wolf traits, implanting modified cell’s nuclei (核) into surrogate (代孕) dogs’ eggs.
The babies, larger than gray wolves, now live in a preserve. They behaved like wolves by howling at two weeks old. But “we have not seen them attempt to hunt live prey”, Colossal’s Paige McNickle told Time magazine.
Some scientists have criticized the project. Professor Nic Rawlence from Otago University questioned using fossil DNA, calling it too damaged to use. “Ancient DNA is like if you put fresh DNA in a 500 degree oven overnight, it comes out like dust,” Rawlence told the BBC． He argued Colossal actually only created “a hybrid (杂交品种)” — a gray wolf with dire wolf features.
Colossal isn’t just reviving the dire wolf. Their list includes the woolly mammoth, dodo and Tasmanian tiger. Their mission goes beyond de-extinction: they also use the same technique to prevent species in danger from disappearing. For example, they brought back four red wolves, an endangered species, in the same way of restoring the dire wolf.
The Center for Biological Diversity predicts that 30% of the planet’s genetic diversity could be lost by 2050. Colossal CEO Ben Lamm argues that genetic engineering is crucial to prevent this loss. Yet some warn there could be consequences. Introducing new species can cause invasive species, while cloning often leads to health problems in animals and surrogates.
20．How did scientists try to restore the dire wolves
A．By obtaining DNA from living dire wolves.
B．By hybridizing different modern wolf species.
C．By studying fossils of dire wolf and surrogating.
D．By using complete DNA of dire wolves to clone.
21．What can be learned about the “restored” dire wolf babies
A．They exhibit some wolf-like behaviors.
B．They have already begun hunting live prey.
C．They are bigger in size than adult gray wolves.
D．They are completely the same as the ancient dire wolves.
22．Why does the author mention red wolves in the 5th paragraph
A．To illustrate the variety of revived species.
B．To highlight the importance of biodiversity.
C．To contrast with the dire wolf’s revival process.
D．To show Colossal’s broader conservation efforts.
23．What is the author’s attitude towards the de-extinction
A．Opposed and critical. B．Objective and cautious.
C．Supportive and optimistic. D．Humorous and unconcerned.
【答案】20．C 21．A 22．D 23．B
【导语】本文是一篇新闻报道。文章主要报道了美国公司Colossal Biosciences通过基因编辑技术尝试复活已灭绝的冰原狼，以及该技术面临的争议和更广泛的应用。
20．细节理解题。根据第二段中“Time magazine said scientists studied fossils (化石) such as a 13,000-year-old dire wolf tooth and a 72,000-year-old ear bone and compared their genes to those of gray wolves to discover differences. They edited 14 key genes in gray wolf blood cells to match dire wolf traits, implanting modified cell’s nuclei into surrogate dogs’ eggs. (据《时代》杂志报道，科学家们研究了化石，比如一颗1.3万年前的冰原狼牙齿和一块7.2万年前的耳骨，并将它们的基因与灰狼的基因进行比较，以发现差异。他们编辑了灰狼血细胞中的14个关键基因，使其与冰原狼的特征相匹配，将修改后的细胞核植入代孕狗的卵子中)”可知，科学家们是通过研究冰原狼的化石，编辑灰狼血细胞中的关键基因，并将其植入代孕狗的卵子中，来尝试恢复冰原狼的。故选C。
21．细节理解题。根据第三段中“The babies, larger than gray wolves, now live in a preserve. They behaved like wolves by howling at two weeks old.(这些幼崽比灰狼大，现在生活在一个保护区里。它们在两周大的时候就像狼一样嚎叫)”可知，这些“复活”的冰原狼幼崽表现出了一些类似狼的行为。故选A。
22．推理判断题。根据第五段中“Colossal isn’t just reviving the dire wolf. Their list includes the woolly mammoth, dodo and Tasmanian tiger. Their mission goes beyond de-extinction: they also use the same technique to prevent species in danger from disappearing. For example, they brought back four red wolves, an endangered species, in the same way of restoring the dire wolf.(Colossal公司不仅仅是在复活冰原狼。它们的名单还包括猛犸象、渡渡鸟和塔斯马尼亚虎。它们的使命不仅仅是让灭绝的物种复活：它们还使用同样的技术来防止濒危物种消失。例如，他们用同样的方法带回了四种濒危物种红狼，就像恢复冰原狼一样)”可推知，作者提到红狼是为了展示Colossal公司在保护濒危物种方面的更广泛努力。故选D。
23．推理判断题。根据第一段中“On April 7, the US company Colossal Biosciences announced restoring this species via de-extinction — a historic first.(4月7日，美国Colossal Biosciences公司宣布通过“去灭绝”技术恢复这一物种，这是历史上的首次)”以及最后一段中“Colossal CEO Ben Lamm argues that genetic engineering is crucial to prevent this loss. Yet some warn there could be consequences. Introducing new species can cause invasive species, while cloning often leads to health problems in animals and surrogates.(Colossal公司首席执行官本 拉姆认为，基因工程对于防止这种损失至关重要。然而，也有人警告说可能会有后果。引入新物种可能会导致入侵物种，而克隆往往会导致动物和代孕者的健康问题)”可推知，作者在文章中既提到了Colossal公司的创新尝试，也提到了科学界的争议和潜在风险，因此作者对于去灭绝技术的态度是客观且谨慎的。故选B。

5G changes the world, creates the future
It is reported that the commercialization of 5G in China is expected to produce a direct economic output of 10.6 trillion yuan (US $1.5 trillion) from 2020 to 2025, plus an indirect economic output of about 24.8 trillion yuan, while directly creating more than 3 million jobs.
Besides profits and job creation, 5G is making other changes in the world.
★No need to meet a doctor in person
Traveling between different cities just to find a better doctor is often time-consuming. With 5G, we could achieve a remote diagnosis and even real-time operations.
The high-level standard for hospital 5G radio access networks is required. The average downlink throughput should be 450 Mbps while the uplink should be 50 Mbps. The average Round-Trip Time (RTT) delay between a medical terminal (终端) and a local medical application platform should be 20ms or below.
★The city with a brain
The “brain of city safety,” otherwise known as the smart city, developed by 360 Total Security, provides another way of dealing with city safety issues.
A highly automatic computerized network, driven by big data, the Internet of Things (IoT) and 5G, has been used to predict or detect emergency cases around the city.
Zhao Weiting, an expert at Smart City Solutions said that the smart city system has changed the way that emergency cases are dealt with.
“In the past, when an emergency case happened, all we could do was deal with it afterward,” said Zhao, “but now the smart brain can collect a large amount of data and analyze it. From this, we can predict a potential case based on abnormal patterns detected by the system and send them to safety departments to make a final decision.”
According to Zhao, the smart city system has already been deployed in the city of Chongqing and Tianjin, and is planned in more cities in the coming years.
★Taking over life-threatening jobs
China Telecom presented its remote control vehicle at an exhibition. The vehicle, hundreds of miles away in Nanjing, gives a real-time reaction based on the signal sent from the simulator (模拟器) in the Beijing International Convention Center. The real-time feedback from the simulator and the live images transmitted from the cameras installed (安装) on the vehicle make it hard to differentiate from a real driving experience.
Such technology could be used in dangerous situations, such as oil drilling (钻探), fire-fighting, or any other emergency response job that could be life-threatening to people on the ground.

5G 改变世界，创造未来
据报道，2020 年至 2025 年期间，中国 5G 商业化预计将直接产生 10.6 万亿元（1.5 万亿美元）的经济产出，间接经济产出约 24.8 万亿元，同时直接创造超过 300 万个就业岗位。
除了盈利和创造就业机会，5G 还在世界范围内引发其他变化。
★无需亲自看医生
为了找更好的医生而在不同城市之间奔波往往耗时费力。有了 5G，我们就能实现远程诊断，甚至实时手术。
医院 5G 无线接入网络的高标准要求平均下行吞吐量达到 450Mbps，上行吞吐量达到 50Mbps。医疗终端与本地医疗应用平台之间的平均往返时间（RTT）延迟应在 20 毫秒或以下。
★有“大脑”的城市
由 360 安全卫士开发的“城市安全大脑”，即智慧城市，为解决城市安全问题提供了另一种途径。一个由大数据、物联网和 5G 驱动的高度自动化的计算机网络已被用于预测或检测城市周边的紧急情况。
智慧城市解决方案专家赵伟廷表示，智慧城市系统改变了处理紧急情况的方式。
赵伟廷说：“过去，当紧急情况发生时，我们只能事后处理，但现在智能大脑可以收集大量数据并进行分析。通过这种方式，我们可以根据系统检测到的异常模式预测潜在的紧急情况，并将其发送给安全部门做出最终决定。”
据赵伟廷介绍，智慧城市系统已经在重庆和天津部署，并计划在未来几年在更多城市推广。
★接管危险工作
中国电信在一次展览会上展示了其远程控制车辆。该车辆位于数百英里外的南京，根据北京国际会议中心模拟器发出的信号做出实时反应。模拟器提供的实时反馈以及安装在车辆上的摄像头传输的实时图像，让人难以区分这与真实的驾驶体验有何不同。
这种技术可用于危险情境，比如石油钻探、灭火或任何其他可能危及地面人员生命的紧急救援工作。

Passage 1
Water is life. It is the source of any possibility for growth and liveliness. That is why water waste is such a big concern in places where water is insufficient. But that’s where Direct Potable Reuse, also known as DPR, can help.
DPR is a method for taking waste water and turning it into drinking water, according to Wastewater Digest. Though the sound of it may make people feel sick, it has been used with great success and to no ill-effect in Namibia for over fifty years.
Namibia is the driest country in sub-Saharan Africa. Its capital, Windhoek, is in the middle of two of the oldest deserts in the world, and is 400 miles away from the nearest river. And yet, over 400 thousand people live in Windhoek, and thanks to a clever method of water reuse, nearly every one of them has access to clean drinking water.
Windhoek built its first water-recycling plant in 1968, leading the area to be referred to as the “birthplace of water-recycling”. According to Positive News reports, in the recycling plant, the wastewater goes through an multi-barrier process which removes pollutants and bacteria in the water. This is similar to how water is filtered (过滤) in nature. The water-recycling plant, however, has an expedited handling procedure. It produces safe drinking water within twenty four hours.
Though Namibia has been successfully using DPR for half a century, it has been slower to catch on in other parts of the world. The greatest roadblock so far has been public opinion. Patty Tennyson, the Vice President of Katz and Associates told Positive News, “Technology has never been the reason why these projects don’t get built — it’s always public or political opposition.”
The time for overcaution (过分谨慎) has passed though. As temperatures increase and the world gets thirstier, this safe and efficient water-saving technology can not be ignored. The success of DPR in Namibia has shown that a little creativity can make even the desert produce flowers.
1．Why does the author mention the position of Windhoek in paragraph 3
A．To present the locals’ poor situation. B．To show the significance of DPR.
C．To describe the scenes of the city. D．To help tourists locate the capital.
2．Which of the following is closet in meaning to the underlined word “expedited” in paragraph 4
A．Safer. B．Similar. C．Faster. D．Premier.
3．What can be inferred about the future of DPR
A．It will be replaced by new technology. B．It will only be used in desert regions.
C．It will be more acceptable in the world. D．It will be ignored in developed countries.
4．What is the best title of the text
A．DPR, a method making a different world B．Water shortage, a big concern in the world
C．Windhoek, the birthplace of water-recycling D．DPR, a technology making people feel sick
【答案】1．B 2．C 3．C 4．A

1．推理判断题。根据第三段“Namibia is the driest country in sub-Saharan Africa. Its capital, Windhoek, is in the middle of two of the oldest deserts in the world, and is 400 miles away from the nearest river. And yet, over 400 thousand people live in Windhoek, and thanks to a clever method of water reuse, nearly every one of them has access to clean drinking water.(纳米比亚是撒哈拉以南非洲最干旱的国家。其首都温得和克位于世界上最古老的两个沙漠中间，距离最近的河流有400英里。然而，超过40万人居住在温得和克，多亏了一种巧妙的水再利用方法，几乎每个人都能获得干净的饮用水)”可推知，作者提及温得和克的位置，是为了凸显其缺水的地理环境，从而体现DPR技术在此地的重要意义。故选B项。
2．词句猜测题。根据第四段中的“This is similar to how water is filtered (过滤) in nature. The water-recycling plant, however, has an expedited handling procedure. It produces safe drinking water within twenty four hours.(这类似于自然界中水的过滤方式。然而，这家水循环工厂有一个expedited处理程序。它能在24小时内生产出安全的饮用水)”可知，与自然界的过滤相比，该工厂的处理程序能在24小时内产出安全饮用水，说明其过程更快，因此“expedited”意为“更快的”。故选C项。
3．推理判断题。根据第五段中的“Though Namibia has been successfully using DPR for half a century, it has been slower to catch on in other parts of the world. The greatest roadblock so far has been public opinion.(尽管纳米比亚成功使用DPR已有半个世纪，但在世界其他地区，它的普及速度较慢。到目前为止，最大的障碍是公众舆论)”以及第六段中的“As temperatures increase and the world gets thirstier, this safe and efficient water-saving technology can not be ignored.(随着气温升高，世界变得更加干旱，这种安全高效的节水技术不容忽视)”可推断，随着全球缺水问题加剧，DPR技术将在世界范围内更易被接受。故选C项。
4．主旨大意题。通读全文，尤其是第一段中的“But that’s where Direct Potable Reuse, also known as DPR, can help.(但这正是直接饮用水再利用（DPR）所能提供帮助的地方)”和最后一段中的“The success of DPR in Namibia has shown that a little creativity can make even the desert produce flowers.(DPR在纳米比亚的成功表明，一点创造力甚至可以让沙漠开花)”可知，文章主要介绍了DPR技术及其带来的积极影响，A选项“DPR，一种改变世界的方法”最能概括全文主旨，是文章的最佳标题。故选A项。
Passage 2
Glass might soon meet a surprising competitor: bamboo. Scientists in China have transformed regular bamboo into a see-through material that keeps out fire and water and reduces smoke, providing an environmentally friendly replacement for traditional glass made from sand. While glass is still widely used in buildings for its clearness, its tendency to break easily, heavy weight and environmental impact have pushed researchers to look for other materials like clear wood — and now bamboo.
Clear wood, made by removing a natural substance called lignin (木质素) and adding plastic-like materials, has been seen as a good renewable option. It is lighter than glass and better at keeping heat out. However, its tendency to catch fire and the slow growth rate of trees make it hard to produce in large amounts: To solve this, researchers at Central South University of Forestry and Technology focused on bamboo, which grows fully in 4-7 years and produces four times more material per farm area compared to trees.
The team applied the methods developed for making wood see-through to bamboo, which has a similar chemical makeup. Specifically, by removing linger, which makes plants look solid, and filling the bamboo fibers with a glass-like liquid called sodium silicate, they changed how light passes through the material, achieving 71.6% clearness. A final water-blocking treatment created three layers: a protective outer coating, a middle layer of silicon dioxide (a common glass ingredient), and a base layer of sodium silicate. The final material showed impressive strength, outshining many common plastics.
Importantly, the clear bamboo showed special fire safety features. Unlike wood-based materials, it didn’t catch fire easily, blocked water, and stopped dangerous smoke and gases from spreading — key benefits for building use. When tested as a base for advanced solar cells, it helped control light better, increasing energy production by 15.29%. This double role suggests it could be used in smart buildings that use sunlight for lighting while creating clean energy. While making this material in large amounts still needs work, this discovery supports environmental goals.
5．Which of the following is one of the reasons for researchers to replace the current widely used glass
A．It’s not clear enough. B．It harms the environment.
C．Its cost is too high. D．It catches fair easily.
6．What features of bamboo makes it a suitable choice for making clear glass
A．Its lighter weight. B．Its clearness. C．Its tall height. D．Its high yield.
7．What does paragraph 3 mainly talk about
A．The production process of the new material.
B．The superb advantages of the new material.
C．The outstanding features of bamboo.
D．The biological construction of bamboo.
8．What can be inferred about the clear bamboo from the last paragraph
A．It has a bright future in smart buildings.
B．It has been produced in large amounts.
C．It may serve as a kind of clean energy.
D．It can clear off the poisonous smoke.
【答案】5．B 6．D 7．A 8．A
【导语】本文是一篇说明文。文章主要介绍了中国科学家研发的一种透明竹材料，该材料具有防火防水、减少烟雾等特性，有望成为传统玻璃的环保替代品。
5．细节理解题。根据第一段“While glass is still widely used in buildings for its clearness, its tendency to break easily, heavy weight and environmental impact have pushed researchers to look for other materials like clear wood — and now bamboo. (虽然玻璃因其清洁性仍被广泛用于建筑中，但它容易破碎、重量大以及对环境的影响促使研究人员寻找其他材料，比如透明木材——现在是竹子。)”可知，传统玻璃存在易碎、重量大和环境危害等问题。故选B。
6．细节理解题。根据第二段“To solve this, researchers at Central South University of Forestry and Technology focused on bamboo, which grows fully in 4-7 years and produces four times more material per farm area compared to trees. (为了解决这个问题，中南林业科技大学的研究人员把重点放在竹子上，竹子在4-7年内生长完全，每个农场生产的材料是树木的四倍。)”可知，竹子生长周期短且单位面积产量高，所以适合作为制作透明玻璃的理想材料。故选D。
7．主旨大意题。根据第三段“Specifically, by removing linger, which makes plants look solid, and filling the bamboo fibers with a glass-like liquid called sodium silicate, they changed how light passes through the material, achieving 71.6% clearness.

Passage 3
Scientists in Australia are testing printed solar panels to power a Tesla on a 15,100-kilometer (9,400-mile) journey beginning in September, which they hope will get the public thinking about steps to help prevent climate change.
The Charge Around Australia (CAA) project will power a Tesla electric car with 18 of the team’s printed plastic solar panels, each 18 meters (59 feet) long, rolling them out beside the vehicle to absorb sunlight when it needs a charge.
Paul Dastoor. the inventor of the printed solar panels, said the University of Newcastle team would be testing not only the endurance of the panels but their potential performance for other applications. “This is actually an ideal test bed to give us information about how we would go about using and powering technology in other remote locations, for example, in space,” Dastoor told Reuters in the town of Gosforth, north of Sydney.
Printed solar is a lightweight, laminated (层压的) plastic that can be made at a cost of less than $10 a square meter. The panels are made on a commercial printer originally used for printing wine labels.
Dastoor said using the panels to power a car would get Australians to think more about electric vehicles and could help ease their “range anxiety.” The community is seeking these sorts of answers to the problems it’s being faced with, day in, day out, around climate change.
On their 84-day Tesla journey, the team plans to visit about 70 schools to give students a taste of what the future may hold. Asked what Elon Musk, creator of the Tesla car and founder of Tesla Inc TSLA．O, might say about the CAA project, Dastoor said he hoped he would be pleased. CAA was “showing how our innovative technology is now combining with his developments to develop new solutions for the planet”, Dastoor said.
9．What can we learn about the printed solar panel
A．It weighs a lot. B．It can be rolled and carried.
C．It can be used at any time of a day. D．It has been applied to power gas cars.
10．What is “range anxiety” in Paragraph 5 probably about
A．The climate is getting worse. B．The solar panels are 100 long.
C．The solar panels are expensive. D．The endurance of the panels is poor.
11．What can be inferred from the last paragraph
A．Musk is pleased with the CAA project.
B．Students are positive about their own future.
C．The electric car lasts 84 days on a single charge.
D．The CCA team and Musk are making efforts for climate changes.
【答案】9．B 10．D 11．D
【导语】本文是一篇说明文。文章介绍了澳大利亚科学家测试印刷太阳能电池板为特斯拉汽车供电的项目，该项目旨在引发公众对防止气候变化的思考，还介绍了电池板特点及项目相关计划。
9．细节理解题。根据第二段“The Charge Around Australia (CAA) project will power a Tesla electric car with 18 of the team’s printed plastic solar panels, each 18 meters (59 feet) long, rolling them out beside the vehicle to absorb sunlight when it needs a charge.(澳大利亚充电之旅(CAA)项目将用该团队的18块印刷塑料太阳能电池板为一辆特斯拉电动汽车供电，每块电池板长18米(59英尺)，当汽车需要充电时，展开它们，铺在车旁以吸收阳光)”可知，这种印刷太阳能电池板可以卷起来携带。故选B项。
10．词句猜测题。根据第五段中“Dastoor said using the panels to power a car would get Australians to think more about electric vehicles and could help ease their ‘range anxiety.’(达斯托尔说，使用这些电池板为汽车供电将让澳大利亚人更多地考虑电动汽车，并有助于缓解他们的‘续航焦虑’)”可知，新的印刷太阳能电池板将让澳大利亚人更多地考虑电动汽车，说明这种电池板缓解了之前的担忧。结合选项可推知，“range anxiety”指的是对“电池板的续航能力差”的焦虑。故选D项。
11．推理判断题。根据最后一段中“CAA was ‘showing how our innovative technology is now combining with his developments to develop new solutions for the planet’, Dastoor said.(达斯托尔说，澳大利亚充电之旅项目‘展示了我们的创新技术如何与他(马斯克)的发展相结合，为地球开发新的解决方案’)”和常识可知，太阳能电池板项目有助于节能减排，是应对地球气候变化的可行解决方案，所以CAA团队和马斯克都在为应对地球气候变化而努力。故选D项。
Passage 4
When Dr. Emily Carter was a young girl, she was fascinated by the way water interacted with different materials in her backyard. She would spend hours watching how rainwater passed through the soil, and how certain plants seemed to grow better in wet. This early curiosity about the natural world’s processes stayed with her as she grew older.
After obtaining degrees in environmental science and materials engineering, Dr. Carter started to think about how to use her knowledge to address a growing problem: water pollution in urban areas. Stormwater runoff, which picks up pollutants like oil, chemicals, and debris from roads and parking lots, was a major contributor to the worse of local water bodies.
She decided to design a new pavement material that could act as a natural filter (过滤器). Her idea was to create a porous (多孔的) concrete that would allow rainwater to pass through while trapping pollutants. Through countless experiments with different aggregates (骨料), binders, and additives, and by studying the behavior of various microorganisms that could potentially break down the trapped pollutants, Dr. Carter constructed small-scale test areas in her city. These areas were equipped with sensors to monitor the flow of water and the levels of pollutants both before and after passing through the new pavement.
As the months passed, The results were remarkable. The pavement significantly reduced pollutants in stormwater runoff. Encouraged by the results, Dr. Carter cooperated with local companies and agencies, aiming to build a city-wide network of pollutant-filtering pavements. Her vision was to give cities a self-cleaning mechanism, using nature’s purification processes to solve environmental problems.
12．What can we learn about Dr. Emily Carter from the first two paragraphs
A．She was interested in urban development.
B．She had a strong desire to study engineering.
C．Her dream was to become a famous scientist.
D．Her childhood curiosity contributed to her later design.
13．Why did Dr. Carter decide to design a new pavement material
A．To deal with water pollution in cities. B．To promote the growth of urban plants.
C．To reduce the cost of road construction. D．To improve the condition of urban roads.
14．What was the key to Dr. Carter's pavement design
A．Installing advanced sensors. B．Using high-quality concrete.
C．Trapping and breaking down pollutants. D．Cooperating with construction companies.
15．What did Dr. Carter hope to achieve in the long run
A．To train more professionals in environmental science.
B．To make her pavement material well-known worldwide.
C．To establish a large-scale pollutant-filtering system in cities.
D．To win more awards for her outstanding environmental research.

Passage 5
The legendary dire wolf—a well-known creature that disappeared around 13,000 years ago and gained fame through HBO’s TV series Game of Thrones—has made an extraordinary return. This is the result of a cutting-edge genetic project by the company Colossal Biosciences, marking the first-ever successful “de-extinction” of a species.
Recently, the company revealed the birth of three healthy dire wolf babies. Their arrival was made possible by combining DNA from ancient dire wolf fossils with the genes of their closest living relative, the grey wolf. To achieve this, scientists used a cloning technique called somatic cell nuclear transfer. They took DNA from a 13,000-year-old tooth and a 72,000-year-old bone, inserted the cell nuclei (体细胞核) into donor egg cells to create embryos (胚胎), and then implanted these embryos into a domestic dog mother, who gave birth in January. Ben Lamm, CEO of Colossal, expressed his excitement, saying, “any sufficiently advanced technology is similar to magic”.
The dire wolf was once a fierce top predator across North America in Ice Age. They preyed on large mammals like horses, bison and potentially mammoths, but after these species went extinct, the dire wolf’s rule also came to an end. According to paleontologist (古生物学家) Julie Meachen, with the loss of their prey, the dire wolf was gradually replaced by the grey wolf.
Dire wolves were larger and stronger than their modern grey relatives, with jaws and shoulders built for powerful hunts. Their revival has attracted both science enthusiasts and pop culture fans alike.
Dr. Christopher Mason, a scientific adviser for Colossal, described the de-extinction of the dire wolf as a transformative leap in genetic engineering. “This is an extraordinary technological leap for both science and conservation,” he stated. “It’s a wonderful example of the power of biotechnology to protect species, both existing and extinct.”
16．How were the dire wolf babies created
A．By combining genes of a grey wolf and a domestic dog.
B．By using a method called somatic cell nuclear transfer.
C．By changing the behavior of modern wolves.
D．By natural reproduction in a lab setting.
17．What caused the dire wolf’s extinction around 13,000 years ago
A．Lack of food. B．Climate change.
C．Human hunting. D．Wolf competition.
18．What’s Dr. Christopher Mason’s view on de-extinction
A．It is a biological experiment with little practical value.
B．It can only be used on species that recently went extinct.
C．It shows biotechnology’s potential to protect and revive species.
D．It has attracted both science enthusiasts and pop culture fans alike.
19．Which of the following would be the best title for the article
A．A TV Series Inspires New Wolf Species Research
B．Scientists Clone Grey Wolves for Species Conservation
C．Dire Wolves Return: Breakthrough in De-Extinction Technology
D．The Predator in Ice Age: the Extraordinary Story of the Dire Wolf

Passage 6
Known for its role in Game of Thrones (《权力的游戏》), the dire wolf (冰原狼) went extinct over 10,000 years ago. On April 7, the US company Colossal Biosciences announced restoring this species via de-extinction — a historic first.
Time magazine said scientists studied fossils (化石) such as a 13,000-year-old dire wolf tooth and a 72,000-year-old ear bone and compared their genes to those of gray wolves to discover differences. They edited 14 key genes in gray wolf blood cells to match dire wolf traits, implanting modified cell’s nuclei (核) into surrogate (代孕) dogs’ eggs.
The babies, larger than gray wolves, now live in a preserve. They behaved like wolves by howling at two weeks old. But “we have not seen them attempt to hunt live prey”, Colossal’s Paige McNickle told Time magazine.
Some scientists have criticized the project. Professor Nic Rawlence from Otago University questioned using fossil DNA, calling it too damaged to use. “Ancient DNA is like if you put fresh DNA in a 500 degree oven overnight, it comes out like dust,” Rawlence told the BBC． He argued Colossal actually only created “a hybrid (杂交品种)” — a gray wolf with dire wolf features.
Colossal isn’t just reviving the dire wolf. Their list includes the woolly mammoth, dodo and Tasmanian tiger. Their mission goes beyond de-extinction: they also use the same technique to prevent species in danger from disappearing. For example, they brought back four red wolves, an endangered species, in the same way of restoring the dire wolf.
The Center for Biological Diversity predicts that 30% of the planet’s genetic diversity could be lost by 2050. Colossal CEO Ben Lamm argues that genetic engineering is crucial to prevent this loss. Yet some warn there could be consequences. Introducing new species can cause invasive species, while cloning often leads to health problems in animals and surrogates.
20．How did scientists try to restore the dire wolves
A．By obtaining DNA from living dire wolves.
B．By hybridizing different modern wolf species.
C．By studying fossils of dire wolf and surrogating.
D．By using complete DNA of dire wolves to clone.
21．What can be learned about the “restored” dire wolf babies
A．They exhibit some wolf-like behaviors.
B．They have already begun hunting live prey.
C．They are bigger in size than adult gray wolves.
D．They are completely the same as the ancient dire wolves.
22．Why does the author mention red wolves in the 5th paragraph
A．To illustrate the variety of revived species.
B．To highlight the importance of biodiversity.
C．To contrast with the dire wolf’s revival process.
D．To show Colossal’s broader conservation efforts.
23．What is the author’s attitude towards the de-extinction
A．Opposed and critical. B．Objective and cautious.
C．Supportive and optimistic. D．Humorous and unconcerned.
