Now, it not only becomes a popular place for people to take a walk, but also a good place for birds and other animals to live in. Li Zhijun is a member of the bird protection organization (组织). He saw the great changes at the park. According to him, Yinchuan Wetland Park is now a famous place for bird photographers. More birds would like to stay here in winter. Besides Yinchuan, many cities in China worked hard to protect wetlands. Wuhan in Hubei Province is known as a “city of a hundred lakes”. The city has five large wetland nature reserves (保护区). Tens of thousands of birds come to stay in winter. Panjin in Liaoning Province is another surprising wetland city. In the past, the city had a lot of pollution because of oil production. But now in the wetlands by the sea, the seagrass turns red every autumn, creating beautiful “red beaches”. Chen Zhihai, a local fishery (渔场) worker, said, “In the past, there were almost no wild fish. Thanks to the hard work of Panjin people, now the wetland is back again!” 1．How was Yinchuan Wetland Park like in the past? A．Almost no grass could grow on the land. B．People liked to go there for a walk. C．Birds stayed there in winter. D．It was a good place for bird photographers. 2．What does the underlined word “it” in Paragraph 1 refer to? A．Waste water. B．Yinchuan Wetland Park. C．Grass. D．Land. 3．Which city is called the “city of a hundred lakes”? A．Yinchuan. B．Shenzhen. C．Panjin. D．Wuhan. 4．Why did Panjin have much pollution in the past? A．Because people put waste water into the rivers. B．Because most birds didn’t come here in winter. C．Because people caused pollution during oil production. D．Because the government didn’t build any wetland nature reserves. 5．Where is this passage probably from? A．A nature magazine. B．A storybook. C．A history poem. D．A safety guide. B By the end of January 2025, the world’s largest iceberg (冰山), A23a, about twice the size of Greater London and standing 130 feet tall, was moving towards South Georgia, a British island near Antarctica. This worries scientists a lot. The iceberg started moving in November 2023 after being stuck (被卡住) on the seafloor for more than 30 years. Experts think it will reach the waters near South Georgia within weeks, which may harm the island’s rich ecosystem. If the huge iceberg gets stuck in the waters around the island, it might block the paths (堵住通道) penguins and seals use to look for food. Penguins and seals might need to travel farther, spending more energy and returning with less food for their babies. As we have seen before, this could cause many young animals to die. Dr Andrew Meijers, a scientist who once watched the iceberg on a research ship, called it a huge “ice wall”. He explained that South Georgia is important for penguins and seals to raise their young. However, some experts believe the ecosystem will return to normal by itself. Ted Scambos, an ice scientist, said the Southern Ocean’s wildlife has survived (幸存) icebergs over thousands of years and can go through this hard time successfully. It is normal for icebergs to break away. However, scientists note this happens more often now because of the warming of the Earth. Rising temperatures melt (融化) ice faster, creating larger icebergs like A23a. Experts predict that A23a will finally break into smaller pieces and melt. However, its influences on South Georgia’s animals could last long. This event is a warning for us. While nature can often return to normal by itself, it is delicate (脆弱的) at the same time. Humans’ actions also can bring risks to it. 1．What makes scientists worried? A．A23a’s great size. B．A23a’s ecosystem. C．A23a’s special height. D．A23a’s moving direction. 2．What may happen after the iceberg hits South Georgia? A．It may change the island’s climate. B．More animals may live on the iceberg. C．It may influence the island’s ecosystem. D．Animals may find more food on the iceberg. 3．What can we know about Andrew Meijers and Ted Scambos? A．They both worry a lot about the iceberg. B．They both call on people to save the ecosystem. C．They have different ideas on the iceberg’s influence. D．They don’t care much about the iceberg’s influence. 4．What can we infer from Paragraph 5? A．There will be more icebergs. B．A23a has been the largest up to now. C．South Georgia’s animals may die out. D．Human’s actions also can bring risks to A23a. 5．What will the passage probably discuss next? A．Why we should protect animals. B．When A23a will break into smaller pieces. C．How human’s activities can influence nature. D．How nature returns to normal by itself. 2. 任务型阅读 Arctic fox (北极狐) is a kind of small fox. It lives in the Arctic.

The next year they can live alone. Today, there are fewer Arctic foxes in the world because people kill them for their fur to make beautiful coats for money.

Now, it not only becomes a popular place for people to take a walk, but also a good place for birds and other animals to live in. Li Zhijun is a member of the bird protection organization (组织). He saw the great changes at the park. According to him, Yinchuan Wetland Park is now a famous place for bird photographers. More birds would like to stay here in winter. Besides Yinchuan, many cities in China worked hard to protect wetlands. Wuhan in Hubei Province is known as a “city of a hundred lakes”. The city has five large wetland nature reserves (保护区). Tens of thousands of birds come to stay in winter. Panjin in Liaoning Province is another surprising wetland city. In the past, the city had a lot of pollution because of oil production. But now in the wetlands by the sea, the seagrass turns red every autumn, creating beautiful “red beaches”. Chen Zhihai, a local fishery (渔场) worker, said, “In the past, there were almost no wild fish. Thanks to the hard work of Panjin people, now the wetland is back again!” 1．How was Yinchuan Wetland Park like in the past? A．Almost no grass could grow on the land. B．People liked to go there for a walk. C．Birds stayed there in winter. D．It was a good place for bird photographers. 2．What does the underlined word “it” in Paragraph 1 refer to? A．Waste water. B．Yinchuan Wetland Park. C．Grass. D．Land. 3．Which city is called the “city of a hundred lakes”? A．Yinchuan. B．Shenzhen. C．Panjin. D．Wuhan. 4．Why did Panjin have much pollution in the past? A．Because people put waste water into the rivers. B．Because most birds didn’t come here in winter. C．Because people caused pollution during oil production. D．Because the government didn’t build any wetland nature reserves. 5．Where is this passage probably from? A．A nature magazine. B．A storybook. C．A history poem. D．A safety guide. 【答案】1．A 1．B 2．D 3．C 4．A 【导语】本文以银川湿地公园的转变开始，展示了湿地保护带来的积极变化。此外，本文还介绍了武汉、盘锦等城市在湿地保护方面所做出的努力及取得的成果。 1．细节理解题。根据第一段中的“The area of Yinchuan Wetland Park was once a place that people didn’t like: waste water caused bad smells and almost no grass could grow on the land”可知，过去的银川湿地公园是一个人们不喜欢的地方：废水造成了恶臭，几乎没有草能在土地上生长。故选A。 2．词义猜测题。联系上下文可知，银川湿地公园现在不仅成为人们散步的好地方，也是鸟类和其他动物栖息的好地方，因此it指代的是银川湿地公园。故选B。 3．细节理解题。根据第三段中的“Wuhan in Hubei Province is known as a ‘city of hundred lakes’”可知，武汉被称为“百湖之城”。故选D。 4．细节理解题。根据第四段中的“In the past, the city had a lot of pollution because of oil production”可知，盘锦过去有许多污染是石油生产造成的。故选C。 5．推理判断题。本文主要介绍了中国的几个城市在湿地保护方面做出的努力和获得的成就，因此最有可能来自自然杂志。故选A。 B By the end of January 2025, the world’s largest iceberg (冰山), A23a, about twice the size of Greater London and standing 130 feet tall, was moving towards South Georgia, a British island near Antarctica. This worries scientists a lot. The iceberg started moving in November 2023 after being stuck (被卡住) on the seafloor for more than 30 years. Experts think it will reach the waters near South Georgia within weeks, which may harm the island’s rich ecosystem. If the huge iceberg gets stuck in the waters around the island, it might block the paths (堵住通道) penguins and seals use to look for food. Penguins and seals might need to travel farther, spending more energy and returning with less food for their babies. As we have seen before, this could cause many young animals to die. Dr Andrew Meijers, a scientist who once watched the iceberg on a research ship, called it a huge “ice wall”. He explained that South Georgia is important for penguins and seals to raise their young. However, some experts believe the ecosystem will return to normal by itself. Ted Scambos, an ice scientist, said the Southern Ocean’s wildlife has survived (幸存) icebergs over thousands of years and can go through this hard time successfully. It is normal for icebergs to break away. However, scientists note this happens more often now because of the warming of the Earth. Rising temperatures melt (融化) ice faster, creating larger icebergs like A23a. Experts predict that A23a will finally break into smaller pieces and melt. However, its influences on South Georgia’s animals could last long. This event is a warning for us. While nature can often return to normal by itself, it is delicate (脆弱的) at the same time. Humans’ actions also can bring risks to it. 1．What makes scientists worried? A．A23a’s great size. B．A23a’s ecosystem. C．A23a’s special height. D．A23a’s moving direction. 2．What may happen after the iceberg hits South Georgia? A．It may change the island’s climate. B．More animals may live on the iceberg. C．It may influence the island’s ecosystem. D．Animals may find more food on the iceberg. 3．What can we know about Andrew Meijers and Ted Scambos? A．They both worry a lot about the iceberg. B．They both call on people to save the ecosystem. C．They have different ideas on the iceberg’s influence. D．They don’t care much about the iceberg’s influence. 4．What can we infer from Paragraph 5? A．There will be more icebergs. B．A23a has been the largest up to now. C．South Georgia’s animals may die out. D．Human’s actions also can bring risks to A23a. 5．What will the passage probably discuss next? A．Why we should protect animals. B．When A23a will break into smaller pieces. C．How human’s activities can influence nature. D．How nature returns to normal by itself. 【答案】1．D 2．C 3．C 4．A 5．C 【导语】本文是一篇说明文，主要讲述了世界上最大的冰山A23a正在向南乔治亚岛移动，这可能会影响当地的生态系统，科学家对此表示担忧，并指出全球变暖导致冰山更频繁地崩解。 【详解】1．第一段指出：“A23a...was moving towards South Georgia... This worries scientists a lot.” 说明让科学家担心的是冰山的移动方向。 2．第二段提到：“...may harm the island’s rich ecosystem.” 第三段进一步说明冰山可能堵塞企鹅和海豹觅食的通道，影响它们的生存，因此冰山会影响岛屿的生态系统。 3．第三段和第四段中，Andrew Meijers 表示担忧，认为冰山会对野生动物造成影响；而Ted Scambos则认为生态系统能够自我恢复。可见两人对冰山影响的看法不同。 4．第五段提到：“scientists note this happens more often now because of the warming of the Earth... creating larger icebergs like A23a.” 由此可推断，全球变暖会导致更多冰山形成。 5．最后一段指出：“Humans’ actions also can bring risks to it.” 说明文章接下来很可能讨论人类活动如何影响自然。 2. 任务型阅读 Arctic fox (北极狐) is a kind of small fox. It lives in the Arctic. It grows about 50 centimeters long, not including (包括) its tail, 30 centimeters tall and weighs from 3 to 7 kilos. The Arctic foxes are white or blue in color.
