As a boy, I always thought people simply bought whatever they need. Whether Grandfather knew this, I didn’t know. One day he said, “Come, I have something for you.” I followed him to a workroom. “You should have a toy boat. You can sail it at Storvassdal,” he said. “Great,” I thought, looking around for the boat. But there was none. Grandfather pointed to a block of wood. “The boat is there,” he said. Then he handed me some tools and showed me how to use them properly. “It’ll be a fine boat, and you’ll make it with your own hands,” he said, “No one can give you what you do for yourself.” The words rang in my head as I worked. The boat was finished. It wasn’t much to look at, but I was proud. Then I sailed it at Storvassdal. We had to return to America. “You cannot bring that boat home with you,” my mother said. We had too much baggage. Feeling sad, I hid my boat under a big rock at Storvassdal. I said good-bye to Grandfather, not knowing I would never see him again. In 1964, I went to Storvassdal with my parents and my wife and children. To my surprise, for 34 years my treasure stayed here, waiting for my return. I felt we three were together again although my grandfather had died 22 years before. I carved (雕刻) “1930” and “1964” on its side and put it back. I returned to the lake in 1968, 1971, 1977 and 1988. Each time I had the boat and carved the year, my grandfather seemed near. My last trip to Storvassdal was in 1991. 26．What lesson did the writer’s grandfather probably teach him? A．Boys should have a toy boat at childhood. B．People can simply buy whatever they need. C．Boys should learn to make a boat out of wood. D．No one can give you what you do for yourself. 27．The underlined words “we three” in Paragraph 6 refer to ________. A．Mother, the boat and me B．Grandfather, the boat and me C．Catherine, Claire and me D．Grandfather, Mother and me 28．According to the passage, we can infer that ________. A．The writer made the boat by himself B．The writer’s mother was born in Norway C．The writer’s grandfather died in Norway D．The boat took the writer back four times 【答案】26．D 27．B 28．C 【导语】本文是一篇记叙文。作者回忆了和祖父在挪威西部山区度过的夏天，祖父教给他自己动手做的东西更有价值。 26．细节理解题。根据第三段“No one can give you what you do for yourself.”可知，祖父告诉作者没有人能给你你自己能给予自己的东西。故选D。 27．词句猜测题。根据第六段“I went to Storvassdal with my parents and my wife and children. To my surprise, for 34 years my treasure stayed here, waiting for my return. I felt we three were together again although my grandfather had died 22 years before.”可知，作者和父母、妻子及孩子们一起去了Storvassdal。令他惊讶的是，他的珍宝在这里等待了34年，等他归来。尽管当时祖父已在22年前去世。由此可推测，we three指的是作者本人、祖父和作者自己制作的船。故选B。 28．推理判断题。根据第一段“I will never forget the tenth summer of childhood with my grandfather in western Norway on the mountain farm”和第二段“You can sail it at Storvassdal”可知，Storvassdal在挪威；结合最后一段“I returned to the lake in 1968, 1971, 1977 and 1988. Each time I had the boat and carved the year, my grandfather seemed near.”可知，作者又回到过这个湖，感觉祖父就在身边。因此可推断，祖父在挪威去世。故选C。 C Shanghai is a world-famous international city in eastern China, lying by the Huangpu River. Over the past century, it has changed greatly, turning from a small village into a modern metropolis that attracts people from all over the world. A hundred years ago, Shanghai was just a quiet fishing and farming village. There were only muddy roads and low, simple houses in the village. Local people lived a slow and peaceful life, making a living mainly by fishing in the Huangpu River and growing crops on the nearby farmland. There were almost no modern buildings at that time, and people usually traveled by small boat or on foot, so it was not easy for them to go to far places. With the development of society, great changes have taken place in Shanghai. Now it is a lively modern city with countless tall buildings. The Oriental Pearl TV Tower and Shanghai Tower have become the famous symbols of the city. It has a convenient modern transport system, including the underground, high-speed trains and wide city roads, which makes traveling in and out of the city very easy. As a business and cultural centre of China, Shanghai also has many large shopping malls, famous museums and wonderful theatres. Every year, millions of visitors from all over the world come here to travel and experience the unique charm of the city. What’s more, Shanghai does well in balancing modern development with traditional culture protection. Historic places like the Bund are well preserved here. People can walk along the old streets, feel the city’s traditional style and at the same time enjoy its modern beauty nearby. Shanghai’s great development is a good example of how a small village can grow into a world-famous international city. 29．What was Shanghai like a hundred years ago? A．An international business and cultural centre. B．A quiet small village for fishing and farming. C．A modern city with many tall buildings. D．A popular travel place with convenient transport. 30．Which of the following is TRUE about modern Shanghai? A．People still mainly travel by boat or on foot. B．It has no famous symbols to represent the city. C．It has a convenient modern transport system. D．Few visitors come to travel here every year. 31．What’s the main idea of the passage? A．The beautiful historic places to visit in Shanghai. B．The great changes of Shanghai in the past century. C．The famous buildings and transport in modern Shanghai. D．The traditional life of local people in old Shanghai. 【答案】29．B 30．C 31．B 【导语】本文是一篇说明文，以上海为例，通过对比其百年前的小渔村面貌与当今现代化国际大都市的景象，展现了一个世纪以来城市在建筑、交通、文化等方面的巨大变迁与发展成就。 29．细节理解题。根据“A hundred years ago, Shanghai was just a quiet fishing and farming village.”可知，一百年前上海是一个安静的渔农村庄，故选B。 30．细节理解题。根据“It has a convenient modern transport system, including the underground, high-speed trains and wide city roads”可知，现代上海拥有便捷的现代化交通系统，故选C。 31．主旨大意题。根据“Over the past century, it has changed greatly, turning from a small village into a modern metropolis”及后文对上海过去和现在的对比介绍，本文核心围绕上海近百年的巨大变化展开，故选B。 D Sunshine, beaches and coconuts (椰子)—these are why people usually go to Hainan. But more than a good place for travellers and foodies, it’s also a wonderland of plants and animals. Hainan Tropical Rainforest National Park is in the south-central part of Hainan Island. It has the best-kept tropical rainforests in China. President Xi visited it in April 2023. The national park covers 4,269 square kilometres, or one-seventh of the island. More than 95 percent of the park is virgin (原始的) forest. The park is home to 3,653 species of vascular plants and 540 species of terrestrial vertebrates. The park is the only home of the world’s most endangered primate (灵长类动物)—the Hainan gibbon. It’s an uncommon species. They look like monkeys, but have no tails. They live in the trees their whole life. Every morning, they whistle loudly to mark their territory (领地). They eat fruits and leaves from more than 130 plants. The number of Hainan gibbons has become larger from fewer than 10 in the 1980s to 36 in 2022. This shows China’s achievements in environmental protection. Not just a sweet home of animals, the park is a “live museum” of amazing plants. More than 400 kinds of plants grow only in Hainan. Cycas hainanensis (海南苏铁) is a wild plant native to the island. With feather-like leaves, this plant can live to be 200 years old. If it lives in the Yangtze River Basin and North China, it grows almost without flowers or fruit. But in Hainan, Cycas hainanensis plants over 10 years old blossom (开花) and have fruit almost every year, thanks to the warm and wet weather. With so many plants and animals, the biodiversity index (指数) of the park—a number to rate species diversity—is as high as 6.28. It is comparable (可比较的) to the Amazon Rainforest in Brazil. That’s why people call the park a treasure for both China and the world. 32．Paragraph 3 is mainly about ________. A．an introduction to the Hainan gibbon B．the views of the park C．the news of the park’s opening D．details of rare plants and animals 33．What do we know about the Hainan gibbon? A．It is a monkey without a tail. B．Its voice sounds like a crying baby. C．It lives on plants and birds. D．It is a species only found in Hainan. 34．From the story, we can infer that a Cycas hainanensis plant ________. A．never blossoms and has fruit B．can only live for 10 years in Hainan C．lives better in warm and wet weather D．first blossoms when it is 10 years old 35．Which of the following may be the writer’s opinion? A．Human activities will surely hurt the rainforest. B．We must start to do something for rare species. C．China has done a great job in protecting the rainforest. D．We should compare our rainforest with the Amazon Rainforest. 【答案】32．A 33．D 34．C 35．C 【导语】本文介绍了海南热带雨林国家公园。 32．主旨大意题。通读第三段可知，本段主要是对海南长臂猿的介绍。故选A。 33．细节理解题。根据第三段中“The park is the only home of the world’s most endangered primate (灵长类动物)—the Hainan gibbon.”可知，海南长臂猿是一种只能在海南找到的物种。故选D。 34．推理判断题。根据第四段中“But in Hainan, Cycas hainanensis plants over 10 years old blossom (开花) and have fruit almost every year, thanks to the warm and wet weather.”可知，海南苏铁在温暖潮湿的环境下生长更好。故选C。 35．观点态度题。根据第三段中“The number of Hainan gibbons has become larger from fewer than 10 in the 1980s to 36 in 2022. This shows China’s achievements in environmental protection.”可知，海南长臂猿的数量从20世纪80年代的不足10只增加到2022年的36只，这表明了中国在环境保护方面取得的成就，因此作者认为中国在保护热带雨林方面做得很好。故选C。 第二部分 本部分共5题，共20分。根据题目要求，完成相应任务。 四、阅读表达（第36-38题每题2分，第39题4分，共10分） 阅读短文，根据短文内容回答问题。 There are many waterfalls in China. Some are big, some are small, they are all beautiful. Today I’ll introduce four of them to you. Huangguoshu Waterfall, which sits in Anshun City, Guizhou Province, is the largest waterfall in China and one of the most famous natural wonders in Asia. With a height of 77.8 meters and a width of 101 meters, it looks like a “white curtain” pouring from the sky, producing thunderous sounds. Every year, millions of people come to visit this natural wonder. Sanxia Waterfall in Yichang, Hubei is a great natural landscape in China. It is one of the widest waterfalls and many people think it is the No.1 waterfall in the world. Hukou Waterfall, located on the Yellow River at the border of Shanxi Province and Shaanxi Province in northern China, is one of the most powerful waterfalls in the country. Known for its dramatic yellow-hued waters and thunderous roar, it is the second-largest waterfall in China (after Huangguoshu Waterfall). People can hear the sound from far away. Lushan Waterfall in Jiangxi is very beautiful. It’s well-known in China and the world because of the poem (诗) by Li Bai: It plunges straight down three thousand feet. As if the Silver River were falling from the Ninth Heaven. 36．How high is Huangguoshu Waterfall? 37．Where is Sanxia Waterfall? 38．Is Hukou Waterfall the largest waterfall in China? 39．Which waterfall do you like best? Why? 【答案】36．77.8 meters 37．In Yichang, Hubei. 38．No, it isn’t. 39．I like Huangguoshu Waterfall best. Because it is the largest waterfall in China and looks like a “white curtain” pouring from the sky. 【导语】本文主要介绍了中国的四个瀑布，包括黄果树瀑布、三峡瀑布、壶口瀑布和庐山瀑布的基本情况。 36．根据黄果树瀑布的描述“With a height of 77.8 meters and a width of 101 meters”可知，黄果树瀑布高77.8米，故填77.8 meters. 37．根据“Sanxia Waterfall in Yichang, Hubei is a great natural landscape in China.”可知，三峡瀑布在湖北宜昌，故填In Yichang, Hubei. 38．根据“Hukou Waterfall…is the second-largest waterfall in China (after Huangguoshu Waterfall).”可知，壶口瀑布不是中国最大的瀑布，故填No, it isn’t. 39．开放性问题，答案不唯一。参考答案I like Huangguoshu Waterfall best.

As a boy, I always thought people simply bought whatever they need. Whether Grandfather knew this, I didn’t know. One day he said, “Come, I have something for you.” I followed him to a workroom. “You should have a toy boat. You can sail it at Storvassdal,” he said. “Great,” I thought, looking around for the boat. But there was none. Grandfather pointed to a block of wood. “The boat is there,” he said. Then he handed me some tools and showed me how to use them properly. “It’ll be a fine boat, and you’ll make it with your own hands,” he said, “No one can give you what you do for yourself.” The words rang in my head as I worked. The boat was finished. It wasn’t much to look at, but I was proud. Then I sailed it at Storvassdal. We had to return to America. “You cannot bring that boat home with you,” my mother said. We had too much baggage. Feeling sad, I hid my boat under a big rock at Storvassdal. I said good-bye to Grandfather, not knowing I would never see him again. In 1964, I went to Storvassdal with my parents and my wife and children. To my surprise, for 34 years my treasure stayed here, waiting for my return. I felt we three were together again although my grandfather had died 22 years before. I carved (雕刻) “1930” and “1964” on its side and put it back. I returned to the lake in 1968, 1971, 1977 and 1988. Each time I had the boat and carved the year, my grandfather seemed near. My last trip to Storvassdal was in 1991. 26．What lesson did the writer’s grandfather probably teach him? A．Boys should have a toy boat at childhood. B．People can simply buy whatever they need. C．Boys should learn to make a boat out of wood. D．No one can give you what you do for yourself. 27．The underlined words “we three” in Paragraph 6 refer to ________. A．Mother, the boat and me B．Grandfather, the boat and me C．Catherine, Claire and me D．Grandfather, Mother and me 28．According to the passage, we can infer that ________. A．The writer made the boat by himself B．The writer’s mother was born in Norway C．The writer’s grandfather died in Norway D．The boat took the writer back four times C Shanghai is a world-famous international city in eastern China, lying by the Huangpu River. Over the past century, it has changed greatly, turning from a small village into a modern metropolis that attracts people from all over the world. A hundred years ago, Shanghai was just a quiet fishing and farming village. There were only muddy roads and low, simple houses in the village. Local people lived a slow and peaceful life, making a living mainly by fishing in the Huangpu River and growing crops on the nearby farmland. There were almost no modern buildings at that time, and people usually traveled by small boat or on foot, so it was not easy for them to go to far places. With the development of society, great changes have taken place in Shanghai. Now it is a lively modern city with countless tall buildings. The Oriental Pearl TV Tower and Shanghai Tower have become the famous symbols of the city. It has a convenient modern transport system, including the underground, high-speed trains and wide city roads, which makes traveling in and out of the city very easy. As a business and cultural centre of China, Shanghai also has many large shopping malls, famous museums and wonderful theatres. Every year, millions of visitors from all over the world come here to travel and experience the unique charm of the city. What’s more, Shanghai does well in balancing modern development with traditional culture protection. Historic places like the Bund are well preserved here. People can walk along the old streets, feel the city’s traditional style and at the same time enjoy its modern beauty nearby. Shanghai’s great development is a good example of how a small village can grow into a world-famous international city. 29．What was Shanghai like a hundred years ago? A．An international business and cultural centre. B．A quiet small village for fishing and farming. C．A modern city with many tall buildings. D．A popular travel place with convenient transport. 30．Which of the following is TRUE about modern Shanghai? A．People still mainly travel by boat or on foot. B．It has no famous symbols to represent the city. C．It has a convenient modern transport system. D．Few visitors come to travel here every year. 31．What’s the main idea of the passage? A．The beautiful historic places to visit in Shanghai. B．The great changes of Shanghai in the past century. C．The famous buildings and transport in modern Shanghai. D．The traditional life of local people in old Shanghai. D Sunshine, beaches and coconuts (椰子)—these are why people usually go to Hainan. But more than a good place for travellers and foodies, it’s also a wonderland of plants and animals. Hainan Tropical Rainforest National Park is in the south-central part of Hainan Island. It has the best-kept tropical rainforests in China. President Xi visited it in April 2023. The national park covers 4,269 square kilometres, or one-seventh of the island. More than 95 percent of the park is virgin (原始的) forest. The park is home to 3,653 species of vascular plants and 540 species of terrestrial vertebrates. The park is the only home of the world’s most endangered primate (灵长类动物)—the Hainan gibbon. It’s an uncommon species. They look like monkeys, but have no tails. They live in the trees their whole life. Every morning, they whistle loudly to mark their territory (领地). They eat fruits and leaves from more than 130 plants. The number of Hainan gibbons has become larger from fewer than 10 in the 1980s to 36 in 2022. This shows China’s achievements in environmental protection. Not just a sweet home of animals, the park is a “live museum” of amazing plants. More than 400 kinds of plants grow only in Hainan. Cycas hainanensis (海南苏铁) is a wild plant native to the island. With feather-like leaves, this plant can live to be 200 years old. If it lives in the Yangtze River Basin and North China, it grows almost without flowers or fruit. But in Hainan, Cycas hainanensis plants over 10 years old blossom (开花) and have fruit almost every year, thanks to the warm and wet weather. With so many plants and animals, the biodiversity index (指数) of the park—a number to rate species diversity—is as high as 6.28. It is comparable (可比较的) to the Amazon Rainforest in Brazil. That’s why people call the park a treasure for both China and the world. 32．Paragraph 3 is mainly about ________. A．an introduction to the Hainan gibbon B．the views of the park C．the news of the park’s opening D．details of rare plants and animals 33．What do we know about the Hainan gibbon? A．It is a monkey without a tail. B．Its voice sounds like a crying baby. C．It lives on plants and birds. D．It is a species only found in Hainan. 34．From the story, we can infer that a Cycas hainanensis plant ________. A．never blossoms and has fruit B．can only live for 10 years in Hainan C．lives better in warm and wet weather D．first blossoms when it is 10 years old 35．Which of the following may be the writer’s opinion? A．Human activities will surely hurt the rainforest. B．We must start to do something for rare species. C．China has done a great job in protecting the rainforest. D．We should compare our rainforest with the Amazon Rainforest. 第二部分 本部分共5题，共20分。根据题目要求，完成相应任务。 四、阅读表达（第36-38题每题2分，第39题4分，共10分） 阅读短文，根据短文内容回答问题。 There are many waterfalls in China.

I’d like to introduce the Yellow Mountain. It is famous for its strange pines, unique rocks, sea of clouds and hot springs. What makes it special is that the scenery changes with seasons and weather. For example, after rain, clouds float like a white ocean around peaks. In winter, it is covered in snow, like a silver world. It attracts many visitors because it offers peace and amazing views. Many photographers come here to capture its stunning beauty. People also enjoy hiking there to get close to nature. I believe everyone should visit it once to feel its magic. 原创精品资源学科网独家享有版权，侵权必究！1 学科网（北京）股份有限公司1 / 2 学科网（北京）股份有限公司 $
