There, swimming gracefully in the clear water, were over 50 rare birds they had never seen in such large numbers before. These were Chinese mergansers（中华秋沙鸭） — a bird so rare that it is called the “giant panda of the water”. The Chinese merganser is a national first-class protected animal. There are only about 3,000 of them left in the entire world. These birds are very picky about where they live. They need clean water, plenty of fish, and a quiet environment. If the water is polluted or there are too many people around, they will simply leave. For a long time, the Gan River in Wan’an was not a good home for them. But things have been changing. The local government has worked hard to clean up the river. They stopped factories from polluting. They asked people not to use too many chemicals（化学品） on their farms. They also set up patrol teams（巡逻队） to watch over the birds and stop anyone from hunting them. In 2019, the first small group of Chinese mergansers was spotted in the area — just a dozen or so. Year by year, the number grew. In the winter of 2025, researchers counted more than 20. And in March 2026, the number jumped to over 50 — double the previous record! “This shows that our water quality is getting better and better,” said a local wildlife officer. “The birds feel safe here now.” The county plans to set up a protected area for the Chinese mergansers, aiming to make the Gan River a permanent winter home for these rare birds. 55.What does the underlined word “picky” in paragraph 2 most likely mean? A. Easy to please. B. Difficult to satisfy（挑剔的）. C. Quick to move. D. Slow to change. 56. Which of the following is TRUE according to the passage? A. The Chinese merganser is common in China. B. The number of Chinese mergansers in Wan’an has doubled in March 2026. C. The local government has done nothing to protect the birds. D. The birds need polluted water to survive. 57. What is the best title for this passage? A. The Most Beautiful Bird in China B. How to Clean a River C. A Rare Bird Finds a Better Home in Jiangxi D. The Dangers of Birdwatching 解析： 55. 答案：B 解析：词义猜测题。picky意为“挑剔的”。后文说它们需要干净的水、大量的鱼和安静的环境，说明很难满足。选B。 56. 答案：B 解析：细节判断题。文中明确说“in March 2026, the number jumped to over 50 — double the previous record”。A错在common；C错在政府做了很多；D错在need polluted water。选B。 57. 答案：C 解析：标题归纳题。文章讲珍稀鸟类中华秋沙鸭在江西找到更好的家园。A太宽泛；B不是重点；D偏离。选C。 B(原创） From a Grey Scar to a Green Wonder If you visit Xinyu in Jiangxi today, you can see a beautiful park with green hills, clear ponds, and lively markets. But just a few years ago, this place looked completely different. It was Jinshishan, a limestone（石灰岩） mine that had been dug for nearly 100 years. The mining had left the mountain with huge holes, fallen rocks, and thick dust. People called it a “grey scar（伤疤）” on the land. In 2022, the local government decided to heal the scar. They did not just fill the holes and plant trees — they did something much more creative. They turned the mine into a park while keeping its history alive. The old lime kilns（石灰窑） became workshops where visitors can learn traditional crafts（手工艺）. The dark mining caves were changed into an adventure hall for children. The dusty pit（坑） was turned into a square with flowing water. Everywhere you look, there are reminders of what this place used to be — but now they are part of a new story. The transformation was not easy. Workers had to make the mountain safe by fixing 200,000 square metres of falling rocks. They used special techniques to make the damaged soil healthy again. They planted forests and created a smart water system. Today, the vegetation coverage（植被覆盖率） has risen from less than 10% to 80%. The park now absorbs about 480 tons of carbon dioxide（二氧化碳） every year. The park also helps the local community. It has created over 120 jobs. Nearby villages have seen more tourists come to eat in their restaurants and stay in their hotels. Since 2025, over 300,000 people have visited the park. The story of Jinshishan has become famous. It has been chosen as a national example of how to restore（修复） old mines. It even serves as a teaching site for officials learning about ecological（生态的） development. One villager said it best: “The mountain used to take from us. Now, it gives back — in beauty, in clean air, and in hope.” 58. What was Jinshishan like before the restoration? A. A beautiful park with green hills. B. A place with huge holes, fallen rocks, and thick dust. C. A busy market with many visitors. D. A forest with clear ponds. 59. What can we infer from the phrase “keeping its history alive”? A. The park removed all signs of mining. B. The park kept some mining features as part of the new design. C. The government built a museum about mining. D. The villagers wrote a book about the mountain. 60. What does the underlined word “transformation” in paragraph 4 probably mean? A. A complete change（彻底改变）. B. A small repair. C. A sudden accident. D. A long wait. 61. How does the park benefit the local people? A. It provides free housing for villagers. B. It creates jobs and brings tourists. C. It gives free food to everyone. D. It builds schools for children. 62. What is the writer’s attitude towards the Jinshishan project? A. Doubtful B. Critical（批评的） C. Positive . D. Uninterested 解析： 58. 答案：B 解析：细节理解题。第二段描述“huge holes, fallen rocks, and thick dust”。选B。 59. 答案：B 解析：推理判断题。“keeping its history alive”指保留原有采矿遗迹作为新设计的一部分。选B。 60. 答案：A 解析：词义猜测题。transformation指“彻底改变”，从矿山变成公园。选A。 61. 答案：B 解析：细节理解题。文中说“created over 120 jobs”和“more tourists”，所以创造就业和带来游客。选B。 62. 答案：C 解析：作者态度题。全文正面描述项目成果，作者态度积极(Positive)。选C。 C The Guardians of Poyang Lake Every winter, a spectacular scene unfolds at Poyang Lake in Jiangxi, China’s largest freshwater lake. About 700,000 migratory birds（候鸟） fly here from as far away as Siberia（西伯利亚）. Among them are white cranes（白鹤） that make up more than 95% of the world’s total population. The lake is also home to about 542 Yangtze finless porpoises（江豚） — nearly 40% of all the porpoises left in China. But protecting this rich ecosystem（生态系统） is hard work. In April 2026, a new tool was added to the protection effort. In the town of Wucheng, known as “China’s Migratory Bird Town”, an Ecological Policing Joint Service Station（生态警务联勤站） was opened. This station brings together the police, wildlife officials, and local communities to work as one team. Using drones（无人机） with AI monitoring（人工智能监控）, patrol boats, and ground patrols, the station can watch over the lake day and night. The station was not built in a day. It came after years of hard work by many people. One of them is Li Chunru, an 80-year-old retired village doctor. Since 1982, Li has been rescuing injured birds on Poyang Lake. In 2013, he used his own money to open a hospital for sick and injured birds. He keeps a diary of every bird he treats, and at the end of each entry, he writes a short poem about his love for the birds. “I hope more people will learn about birds and love them,” Li says. “Let the protection of Poyang Lake pass from generation to generation.” Thanks to efforts like these, the ecosystem of Poyang Lake is recovering. Porpoise numbers are rising. Rare birds are becoming more common. Just this spring, 16 ibises（朱鹮，一种珍稀鸟类） — a bird so rare it is called the “wetland rainbow（湿地彩虹）” — returned to nest in Yongxiu County for the second year in a row. It is a reminder that when people work together, nature has a remarkable ability to heal. 63.What does the word “They” in paragraph 2 refer to? A. The white cranes. B. The finless porpoises. C. The police and wildlife officials. D. The migratory birds. 64. What is the main idea of paragraph 3? A. The new station uses high technology. B. Li Chunru is a hero who has protected birds for many years. C. Poyang Lake is the largest freshwater lake in China. D. Ibises are returning to Yongxiu County. 65. What can we infer from Li Chunru’s story? A. He is very rich. B. He loves birds deeply and is willing to spend his own money to help them. C. He works for the government. D. He only started protecting birds in 2020. 66. Why are the 16 ibises mentioned in paragraph 4? A. To show that ibises are the most beautiful birds. B. To prove that the ecosystem of Poyang Lake is recovering. C. To explain why the lake is famous. D. To compare ibises with cranes. 67. Which of the following best describes the structure of the passage? A. Problem → Solution → Result → Conclusion B. Cause → Effect → Cause → Effect C. Time order from past to future D. Comparison between two places 解析： 63. 答案：C 解析：代词指代题。前文提到“the police, wildlife officials, and local communities”，They指代这些人。选C。 64. 答案：B 解析：段落主旨题。第三段主要讲李春如保护鸟类的事迹。选B。 65. 答案：B 解析：推理判断题。他用自己钱开医院、写日记写诗，说明他深爱鸟类并愿意付出。选B。 66. 答案：B 解析：写作意图题。提到16只朱鹮回来筑巢是为了证明生态系统正在恢复。选B。 67. 答案：A 解析：篇章结构题。文章先提出问题（保护不易），再给出解决方案（警务站、李春如等），接着展示结果（江豚增加、朱鹮回归），最后结论（众人努力自然可恢复）。结构为问题→解决→结果→结论。选A。 A Silent Messenger of Clean Water On March 29, 2026, scientists working in Guanshan National Nature Reserve in Jiangxi announced an exciting discovery. They had found two new species of caddisflies（石蛾） — small insects that look like tiny moths（蛾子）. The two new species are called the five-branched caddisfly and the spiny（多刺的） caddisfly. They live near streams. As larvae（幼虫）, they spend their lives in the water. This makes them very sensitive to water quality. If the water is polluted, they cannot survive. Because of this, scientists call them “bioindicators（生物指示剂）” — living things that tell us whether the environment is healthy. Finding these two new species is good news. It means the streams in Guanshan National Nature Reserve are clean and healthy. “This discovery fully shows the important ecological function of the reserve as a home for rare species and a gene bank（基因库） of life,” said a senior engineer who took part in the study. Guanshan is located in the mountains of northwestern Jiangxi. It has well-preserved forests and complex stream systems. These provide perfect homes for water insects like caddisflies. Discovering new species is not just about adding names to a list. Each new species teaches us something about how life adapts to its environment. It also reminds us that there is still so much we do not know about the natural world — even in places we have been studying for years. Every time scientists explore a stream or walk through a forest, they might find something new. And every time they do, they are reminded of the same lesson: nature is full of wonders, but only if we keep it healthy. 68. Why are caddisflies called “bioindicators”? A. Because they are very large insects. B. Because their presence or absence shows water quality. C. Because they can predict earthquakes. D. Because they are the only insects in the reserve. 69. What does the underlined word “adapts” in paragraph 5 most likely mean? A. Changes to fit new conditions（适应）. B. Fights against enemies. C. Reproduces quickly. D. Moves to a new place. 70. What can we learn from the last paragraph? A. Scientists have discovered everything about Guanshan. B. There is still much unknown about nature that needs protection. C. Exploring nature is dangerous. D. Only professionals should visit nature reserves. 71. What is the main purpose of this passage? A. To advertise Guanshan as a tourist destination. B. To explain how to catch caddisflies. C. To report a scientific discovery and its meaning. D. To compare different types of insects. 72. Which statement about Guanshan National Nature Reserve is NOT true according to the passage? A. It has well-preserved forests. B. It is located in the mountains of northwestern Jiangxi. C. Two new species of caddisflies were found there.D. The water in Guanshan is heavily polluted. 解析： 68. 答案：B 解析：细节理解题。文中说“their presence or absence shows water quality”。选B。 69. 答案：A 解析：词义猜测题。adapt意为“适应”，即改变以适应新环境。选A。 70. 答案：B 解析：推理判断题。最后一段说“there is still so much we do not know”，因此还有很多未知需要保护。选B。 71. 答案：C 解析：写作目的题。文章报道了发现新物种的科学发现及其意义。选C。 72. 答案：D 解析：判断正误题。文中说发现新物种意味着水是清洁的，因此D“水被严重污染”是错误的。选D。 B)请先阅读下面短文，掌握其大意，然后根据短文内容从下面方框内的七个选项中选择五个还原到文中，使短文意思通顺、结构完整，并在答题卡上将其序号涂黑。一空一句。 The First Step to Saving Nature: Knowing It Do you know the name of the waterfall in the photo on the first page of this unit?

I have two main reasons. First, nature gives us clean air, water, and food. Without a healthy environment, we cannot live well. Second, protecting nature means protecting the amazing animals that call it home. Let me tell you a true story from my home province, Jiangxi. In Wan‘an County, over 50 Chinese mergansers — a bird called the “giant panda of the water” — came back to the Gan River in 2026. Their number doubled from before! Why? Because the government cleaned up the river and stopped pollution. This shows that when we protect nature, nature returns the favor. I can also do small things to help. I never leave trash behind when I visit natural places. I also try to walk or bike instead of taking a car whenever I can. I hope you can come to Jiangxi one day. I will take you to see our beautiful lakes, mountains, and birds!

There, swimming gracefully in the clear water, were over 50 rare birds they had never seen in such large numbers before. These were Chinese mergansers（中华秋沙鸭） — a bird so rare that it is called the “giant panda of the water”. The Chinese merganser is a national first-class protected animal. There are only about 3,000 of them left in the entire world. These birds are very picky about where they live. They need clean water, plenty of fish, and a quiet environment. If the water is polluted or there are too many people around, they will simply leave. For a long time, the Gan River in Wan’an was not a good home for them. But things have been changing. The local government has worked hard to clean up the river. They stopped factories from polluting. They asked people not to use too many chemicals（化学品） on their farms. They also set up patrol teams（巡逻队） to watch over the birds and stop anyone from hunting them. In 2019, the first small group of Chinese mergansers was spotted in the area — just a dozen or so. Year by year, the number grew. In the winter of 2025, researchers counted more than 20. And in March 2026, the number jumped to over 50 — double the previous record! “This shows that our water quality is getting better and better,” said a local wildlife officer. “The birds feel safe here now.” The county plans to set up a protected area for the Chinese mergansers, aiming to make the Gan River a permanent winter home for these rare birds. 55.What does the underlined word “picky” in paragraph 2 most likely mean? (词义猜测题) A. Easy to please. B. Difficult to satisfy（挑剔的）. C. Quick to move. D. Slow to change. 56. Which of the following is TRUE according to the passage? (细节判断题) A. The Chinese merganser is common in China. B. The number of Chinese mergansers in Wan’an has doubled in March 2026. C. The local government has done nothing to protect the birds. D. The birds need polluted water to survive. 57. What is the best title for this passage? (标题归纳题) A. The Most Beautiful Bird in China B. How to Clean a River C. A Rare Bird Finds a Better Home in Jiangxi D. The Dangers of Birdwatching B(原创） From a Grey Scar to a Green Wonder If you visit Xinyu in Jiangxi today, you can see a beautiful park with green hills, clear ponds, and lively markets. But just a few years ago, this place looked completely different. It was Jinshishan, a limestone（石灰岩） mine that had been dug for nearly 100 years. The mining had left the mountain with huge holes, fallen rocks, and thick dust. People called it a “grey scar（伤疤）” on the land. In 2022, the local government decided to heal the scar. They did not just fill the holes and plant trees — they did something much more creative. They turned the mine into a park while keeping its history alive. The old lime kilns（石灰窑） became workshops where visitors can learn traditional crafts（手工艺）. The dark mining caves were changed into an adventure hall for children. The dusty pit（坑） was turned into a square with flowing water. Everywhere you look, there are reminders of what this place used to be — but now they are part of a new story. The transformation was not easy. Workers had to make the mountain safe by fixing 200,000 square metres of falling rocks. They used special techniques to make the damaged soil healthy again. They planted forests and created a smart water system. Today, the vegetation coverage（植被覆盖率） has risen from less than 10% to 80%. The park now absorbs about 480 tons of carbon dioxide（二氧化碳） every year. The park also helps the local community. It has created over 120 jobs. Nearby villages have seen more tourists come to eat in their restaurants and stay in their hotels. Since 2025, over 300,000 people have visited the park. The story of Jinshishan has become famous. It has been chosen as a national example of how to restore（修复） old mines. It even serves as a teaching site for officials learning about ecological（生态的） development. One villager said it best: “The mountain used to take from us. Now, it gives back — in beauty, in clean air, and in hope.” 58. What was Jinshishan like before the restoration? A. A beautiful park with green hills. B. A place with huge holes, fallen rocks, and thick dust. C. A busy market with many visitors. D. A forest with clear ponds. 59. What can we infer from the phrase “keeping its history alive”? A. The park removed all signs of mining. B. The park kept some mining features as part of the new design. C. The government built a museum about mining. D. The villagers wrote a book about the mountain. 60. What does the underlined word “transformation” in paragraph 4 probably mean? A.

It creates jobs and brings tourists. C. It gives free food to everyone. D. It builds schools for children. 62. What is the writer’s attitude towards the Jinshishan project? A. Doubtful B. Critical（批评的） C. Positive . D. Uninterested C The Guardians of Poyang Lake Every winter, a spectacular scene unfolds at Poyang Lake in Jiangxi, China’s largest freshwater lake. About 700,000 migratory birds（候鸟） fly here from as far away as Siberia（西伯利亚）. Among them are white cranes（白鹤） that make up more than 95% of the world’s total population. The lake is also home to about 542 Yangtze finless porpoises（江豚） — nearly 40% of all the porpoises left in China. But protecting this rich ecosystem（生态系统） is hard work. In April 2026, a new tool was added to the protection effort. In the town of Wucheng, known as “China’s Migratory Bird Town”, an Ecological Policing Joint Service Station（生态警务联勤站） was opened. This station brings together the police, wildlife officials, and local communities to work as one team. Using drones（无人机） with AI monitoring（人工智能监控）, patrol boats, and ground patrols, the station can watch over the lake day and night. The station was not built in a day. It came after years of hard work by many people. One of them is Li Chunru, an 80-year-old retired village doctor. Since 1982, Li has been rescuing injured birds on Poyang Lake. In 2013, he used his own money to open a hospital for sick and injured birds. He keeps a diary of every bird he treats, and at the end of each entry, he writes a short poem about his love for the birds. “I hope more people will learn about birds and love them,” Li says. “Let the protection of Poyang Lake pass from generation to generation.” Thanks to efforts like these, the ecosystem of Poyang Lake is recovering. Porpoise numbers are rising. Rare birds are becoming more common. Just this spring, 16 ibises（朱鹮，一种珍稀鸟类） — a bird so rare it is called the “wetland rainbow（湿地彩虹）” — returned to nest in Yongxiu County for the second year in a row. It is a reminder that when people work together, nature has a remarkable ability to heal. 63.What does the word “They” in paragraph 2 refer to? A. The white cranes. B. The finless porpoises. C. The police and wildlife officials. D. The migratory birds. 64. What is the main idea of paragraph 3? A. The new station uses high technology. B. Li Chunru is a hero who has protected birds for many years. C. Poyang Lake is the largest freshwater lake in China. D. Ibises are returning to Yongxiu County. 65. What can we infer from Li Chunru’s story? A. He is very rich. B. He loves birds deeply and is willing to spend his own money to help them. C. He works for the government. D. He only started protecting birds in 2020. 66. Why are the 16 ibises mentioned in paragraph 4? A. To show that ibises are the most beautiful birds. B. To prove that the ecosystem of Poyang Lake is recovering. C. To explain why the lake is famous. D. To compare ibises with cranes. 67. Which of the following best describes the structure of the passage? A. Problem → Solution → Result → Conclusion B. Cause → Effect → Cause → Effect C. Time order from past to future D. Comparison between two places D A Silent Messenger of Clean Water On March 29, 2026, scientists working in Guanshan National Nature Reserve in Jiangxi announced an exciting discovery. They had found two new species of caddisflies（石蛾） — small insects that look like tiny moths（蛾子）. The two new species are called the five-branched caddisfly and the spiny（多刺的） caddisfly. They live near streams. As larvae（幼虫）, they spend their lives in the water. This makes them very sensitive to water quality. If the water is polluted, they cannot survive. Because of this, scientists call them “bioindicators（生物指示剂）” — living things that tell us whether the environment is healthy. Finding these two new species is good news. It means the streams in Guanshan National Nature Reserve are clean and healthy. “This discovery fully shows the important ecological function of the reserve as a home for rare species and a gene bank（基因库） of life,” said a senior engineer who took part in the study. Guanshan is located in the mountains of northwestern Jiangxi. It has well-preserved forests and complex stream systems. These provide perfect homes for water insects like caddisflies. Discovering new species is not just about adding names to a list. Each new species teaches us something about how life adapts to its environment. It also reminds us that there is still so much we do not know about the natural world — even in places we have been studying for years. Every time scientists explore a stream or walk through a forest, they might find something new. And every time they do, they are reminded of the same lesson: nature is full of wonders, but only if we keep it healthy. 68. Why are caddisflies called “bioindicators”? (细节理解题) A. Because they are very large insects. B. Because their presence or absence shows water quality. C. Because they can predict earthquakes. D. Because they are the only insects in the reserve. 69. What does the underlined word “adapts” in paragraph 5 most likely mean? (词义猜测题) A. Changes to fit new conditions（适应）. B. Fights against enemies. C. Reproduces quickly. D. Moves to a new place. 70. What can we learn from the last paragraph? (推理判断题) A. Scientists have discovered everything about Guanshan. B. There is still much unknown about nature that needs protection. C. Exploring nature is dangerous. D. Only professionals should visit nature reserves. 71. What is the main purpose of this passage? (写作目的题) A. To advertise Guanshan as a tourist destination. B. To explain how to catch caddisflies. C. To report a scientific discovery and its meaning. D. To compare different types of insects. 72. Which statement about Guanshan National Nature Reserve is NOT true according to the passage? (细节判断正误题) A. It has well-preserved forests. B. It is located in the mountains of northwestern Jiangxi. C. Two new species of caddisflies were found there.D. The water in Guanshan is heavily polluted.
