For nearly forty years, he has led his villagers out of poverty (贫困) and built a happy home, earning him the title of the “New Era Iron (铁) Man Farmer”. In 1987, the 25-year-old Fan returned to his hometown as the village Party Branch Secretary. At that time, Zhoutaizi Village was a poor mountain village with 80,000 yuan in debt. Fan made up his mind to make a change. He led villagers to build roads, bridges, and factories, and to plant fruit trees. Long ago, Zhoutaizi Village was very poor. Young Fan Zhenxi decided to lead villagers to change their life. He worked hard day and night to develop businesses and build a better village. Unluckily, he got a serious illness. But he never gave up. He kept working for villagers even when he was weak. He cared about people’s life more than his own health. Under his leadership, the poor village became rich and beautiful. Villagers live happy lives now. Fan Zhenxi is great and selfless (无私的). He never thinks about himself too much. He always puts the villagers first in everything. His spirit teaches us to be brave, responsible and helpful. Many people are moved by his strong will and kindness. His story spreads widely and encourages lots of teenagers.

Xiajiang Village in Zhejiang Province is a good example. It has turned from a quiet and poor place into a modern and lively one, especially in housing and travelling. In the past, villagers in Xiajiang Village lived in old houses made of wood and mud (泥). The walls were thin, so the houses were cold in winter and hot in summer. There were no clean toilets, and people had to carry water from a river far away every day. Life was hard and inconvenient. Now, with government support and more money from the growing economy, these old houses are gone. New houses stand in rows in Xiajiang Village, with bright rooms and clean yards. They use clean energy for lighting and heating, which helps reduce pollution. Villagers in Xiajiang Village now live comfortably and safely. Travelling in Xiajiang Village has improved greatly too. Years ago, the village only had narrow dirt roads. When it rained, the roads became dirty. Villagers walked or rode bikes to the town, which took several hours. Selling produce was difficult because of bad roads. Today, wide new roads connect Xiajiang Village to the city. Buses run four times a day, and many families in the village have their own cars. More tourists come to visit Xiajiang Village and local farmers can sell their fruit and vegetables to big cities quickly. New ways of travelling bring more jobs and money to Xiajiang Village. These changes in Xiajiang Village take place because of rural revitalization. It gives the village support and money. Economy provides enough money for building houses and roads, while technology makes life easier and smarter. Xiajiang Village is becoming richer and more beautiful. It is believed that all Chinese villages will have a bright future. 1．What’s the characteristic of the new houses in Xiajiang Village? A．They are usually built in a circle. B．They are made of stone and wood. C．They are environmentally friendly. D．They are joined to a river far away. 2．How does the writer describe travelling in Paragraph 3? A．By showing reasons and results. B．By showing experiences and feelings. C．By comparing the past with the present. D．By comparing advantages with disadvantages. 3．What leads to the increase in tourists to Xiajiang Village? A．Its beautiful view. B．Its perfect position. C．Its new technology. D．Its improved traffic. 4．Which can be the best title (标题) for the text? A．From Mud to Hope B．Fast Travel, Slow Life C．From Home to Traffic D．Small House, Big Village 【答案】1．C 2．C 3．D 4．A 【导语】本文主要以浙江省下姜村为典型案例，讲述了乡村振兴战略推动下，中国乡村在居住条件、交通旅游等领域发生的巨大变化，展现了乡村发展的成果，展望了中国乡村未来的光明前景。 1．根据第二段中“They use clean energy for lighting and heating, which helps reduce pollution.”可知新房子使用清洁能源，具有环保的特点。 2．第三段首先用“Years ago…”描述了过去的道路和交通状况，接着用“Today…”描述了现在的状况。作者通过对比“past”和“present”来展现交通的巨大改善。 3．根据第三段内容，宽新的道路连接了村庄与城市，公交车和私家车增多，紧接着提到“More tourists come to visit Xiajiang Village”。由此可见，交通状况的改善（improved traffic）是游客增多的直接原因。 4．文章核心讲述下姜村从过去贫穷泥泞的旧村庄，在乡村振兴带动下变成富裕美丽、充满希望的新村，“From Mud to Hope”精准概括了村庄的发展变化与前景。 阅读材料，根据其内容回答文后各个小题。 Great changes are taking place in Tianshui, Gansu these years.

Students from different schools often go to the parks or hills to plant trees. They know trees can help clean the air and make our city greener.”可知，天水的学生们参与到了保护环境的行动当中。 4．根据文章开头“More new projects, beautiful activities and green ideas make our hometown better and better.”以及最后一段“It is not only an old city with a long history but also a modern city full of life.”可知，本文主要讲述天水市的巨大变化。 5．文章第四段“The government is building new roads and railways to make traffic easier.”提到了修建新的公路和铁路；第三段“Students from different schools often go to the parks or hills to plant trees.”提到了种植更多树木；第三段“They use reusable cloth bags instead.”提到了使用可重复利用的布袋。故只有“开更多工厂发展经济”没有被提及。 Over the past few years, great changes have taken place in the countryside of Hainan Province, and Shenchong Village in Danzhou is a perfect example. Tourism has helped locals live better lives. For example, 56-year-old He Sanjie once made a living by fishing. Now he works as a guard in the village’s tourist area, where old volcanic rocks have been built into paths, theaters and nice homestays (民宿). Before tourism developed, Shenchong Village had 810 registered (登记的) people, but only about 100 lived there. Most villagers left for big cities. Now the empty stone houses have become warm and bright homestays. Roads are wider, and living conditions have improved greatly. He Sanjie says the busiest season lasts from spring to autumn. He can make over 50,000 yuan a year just from land rent (租金). “In winter, we can stay in warm houses and have free time. We couldn’t do this before. At that time, we only fished and hardly made enough money,” he adds. With the rise of tourism, the village has grown fast. In the first few months, around 40,000 visitors came. More young people are now returning from big cities to work in their hometown because they can look after their families and help build the village at the same time. Thanks to government policies (政策), villagers now have more ways to make a living and enjoy a more comfortable life. 1．What did He Sanjie do before? A．He ran a shop. B．He was a fisherman. C．He worked as a guard. 2．When is the busiest tourist season in Shenchong Village? A．From winter to spring. B．From autumn to winter. C．From spring to autumn. 3．Why did many young people return to Shenchong Village? A．Because big cities were too crowded. B．Because they didn’t like their jobs in cities. C．Because they could work and look after their families. 4．How is the passage mainly organized? A．By showing an example and describing changes. B．By giving opinions and explaining reasons. C．By comparing different places in Hainan. 5．What is the best title for the passage? A．The History of Shenchong Village. B．Tourism Changes Shenchong Village. C．Beautiful Villages in Hainan. 【答案】1．B 2．C 3．C 4．A 5．B 【导语】本文是一篇说明文，主要讲述了海南省儋州市神冲村在旅游业发展下发生的巨大变化。 1．第一段指出神冲村是变化的典型例子，第二段进一步说明：“56-year-old He Sanjie once made a living by fishing.”，这直接说明他过去以捕鱼为生。 2．第四段他的话直接说明：“He Sanjie says the busiest season lasts from spring to autumn.”，这直接回答了最繁忙的旅游季节是从春季到秋季。 3．第五段说明年轻人返乡的原因：“More young people are now returning from big cities to work in their hometown because they can look after their families and help build the village at the same time.”，这说明他们既能工作又能照顾家人。 4．文章结构分析：第一段引出“Shenchong Village in Danzhou is a perfect example”，随后各段通过个人经历、村庄人口变化、收入变化等具体细节描述旅游业带来的改变，属于“举例+描述变化”的组织方式。 5．全文围绕旅游业如何改变神冲村展开：从过去村民外出打工、生活困难，到现在旅游业发展、生活改善、年轻人返乡。因此最佳标题为“Tourism Changes Shenchong Village”。 Nowadays, millions of Chinese leave the countryside to search for work in the cities. Among these is Zhong Wei, a 46-year-old husband and father. He has lived in Wenzhou for the last 13 years. With a hard job in a crayon factory, he doesn’t find much time to visit his hometown. “I used to return home at least once a year, but I haven’t been back for almost three years now. It’s a shame, but I just don’t have the time.” he says. Many people like Zhong Wei regard with great interest how their hometowns have changed. Perhaps large hospitals and new roads have appeared. In many places, the government has also built new schools and sent teachers from the cities to help. “I noticed that’s true of my hometown,” adds Zhong Wei. “Children have learned to read and count at my old primary school since the mid-20th century. But now the buildings are really old. I hear they’re going to build a new school there.” Zhong Wei thinks such developments are good, and he also knows that his hometown cannot always stay the same. According to Zhong Wei, however, some things will never change. “In my hometown, there was a big old tree opposite the school. It is still there and has become quite a symbol of the place. Most of the children in my time liked to play together under that big tree, especially during the summer holidays. It was such a happy childhood. Our hometown has left many soft and sweet memories in our hearts.” 1．Why hasn’t Zhong Wei been back to his hometown for almost three years? A．Because he doesn’t miss his hometown at all. B．Because he lives far away from the countryside. C．Because he is too busy with his work in the city. D．Because he dislikes the changes there. 2．What does the big old tree in Zhong Wei’s hometown represent? A．The new buildings built by the government. B．The symbol of happy moments in the past. C．The plan to cut down old trees in the near future. D．The crowded and busy life in the small town. 3．Which of the following is TRUE according to the passage? A．Zhong Wei has returned home many times in recent years. B．The government has sent doctors to help in the countryside. C．Zhong Wei thinks the developments in his hometown are good. D．Everything in his hometown has changed. 【答案】1．C 2．B 3．C 【导语】本文讲述了在外务工者钟伟的故事，通过他的视角展现了人们离开家乡到城市工作的现状，以及家乡在发展变化中保留的不变回忆，探讨了家乡的变与不变。 1．根据文章第一段钟伟的描述：“With a hard job in a crayon factory, he doesn’t find much time to visit his hometown…but I haven’t been back for almost three years now. It’s a shame, but I just don’t have the time.”，可以看出他没回家的原因是在城市工作太忙，没有时间。 2．根据文章最后一段：“In my hometown, there was a big old tree opposite the school…Most of the children in my time liked to play together under that big tree…It was such a happy childhood. Our hometown has left many soft and sweet memories in our hearts.”，这棵大树是钟伟童年快乐时光的象征，承载着他的美好回忆。 3．根据文章内容逐一判断。A选项：钟伟说自己近三年没回家，与“returned home many times in recent years”矛盾，错误；B选项：文中提到“sent teachers from the cities to help”，而非“sent doctors”，错误；C选项：文中明确写了“Zhong Wei thinks such developments are good”，与原文一致，正确；D选项：文中提到“some things will never change”，并非一切都变了，错误。故选C。 “As a new Shenzhener, being led to check out the history of my city is really a wonderful experience,” said a participant in her online blog, after she took part in a cultural tour led by Mary Ann O’Donnell, an American anthropologist (人类学家) who has been based in Shenzhen since the 1990s. The Shuiwei tour, organized by Handshake 302, a public art organization, was one of a series of tours that will take visitors to a total of seven places of cultural and historical importance in Shenzhen. Take Metro Line 4 or 7, get off at Fumin Station, walk a few steps, and you will get to the heart of Shuiwei. “What’s important is not what did or did not happen, but how the stories we tell become history, and how we use the history to shape our identities,” said O’Donnell. Along the years, people in Shuiwei made a living by fishing and producing sea salt. However, the practical influence of “water” gradually fell off. Around the 1980s, villagers travelled to and from Hong Kong by boat to buy daily necessities or unusual objects and resell them in Shenzhen. Meanwhile, village renovation and industrialization (工业化) turned Shuiwei into a landlocked region. The village soon changed its livelihood from fishing and agriculture (农业) to manufacturing (制造业) and real estate (房地产业). Handshake buildings are everywhere. The rock museum in the village, which exhibits hundreds of valuable rocks collected from all over the world, also shows the transition from “water” to “land” in Shuiwei’s cultural geography, according to O’Donnell. 1．How many metro lines which can take visitors to the heart of Shuiwei? A．2. B．3. C．4. D．7. 2．What did the writer mention to show the importance of “water” in people’s lives in Shuiwei? A．Hand-shake buildings. B．The rock museum. C．Fishing and producing sea salt. D．Manufacturing and real estate. 3．What is O’Donnell’s attitude towards history according to her words? A．History is about recording true facts exactly. B．History helps people build their sense of identity. C．History should be kept unchanged forever. D．History is less important than modern life. 4．What does the underlined word “transition” in the last paragraph probably mean? A．价值 B．转变 C．渊源 D．典故 5．What is the author’s main purpose in writing this passage? A．To call on people to protect traditional fishing culture. B．To explain why Shuiwei has so many hand-shake buildings. C．To introduce Shuiwei's historical changes and cultural meaning. D．To teach readers how to visit places of interest in Shenzhen. 【答案】1．A 2．C 3．B 4．B 5．C 【导语】本文主要介绍了深圳水围村的文化之旅，探讨了该地从传统的渔业制盐到现代制造业及房地产业的历史变迁，并深度解析了历史对塑造个人及城市身份认同的重要意义。 1．第三段明确指出：“Take Metro Line 4 or 7, get off at Fumin Station…you will get to the heart of Shuiwei.”。列举了4号线和7号线共两条地铁线可以到达水围。 2．第五段第一句提到：“…people in Shuiwei made a living by fishing and producing sea salt.”。直接说明了在过去水围村居民依靠捕鱼和产盐维持生计，以此展现了“水”对当地人生活的重要性。 3．第四段指出O’Donnell的话：“…how we use the history to shape our identities…”。其中“identity”意为“身份、特征”，这表明她认为历史能够帮助人们构建并确立自己的身份感。 4．根据最后一段语境：“…also shows the transition from ‘water’ to ‘land’ in Shuiwei’s cultural geography…”。文章前文详细描述了水围从渔业转向工业和房地产业的过程，由此可以推断该词意为“转变”。 5．通读全文可知，文章先由文化之旅引出话题，接着描述水围村的具体交通和历史变迁过程，并解析其背后的文化价值。选项C“介绍水围的历史变迁及文化意义”高度概括了文章的写作目的。 ① Living in China has made me realize how convenient life can be. It is much better than I ever thought, and it has completely changed my way of life. ② The moment I came to this country, a wave of pleasant surprise washed over me. The public travel system, especially in big cities, is great. The underground networks cover almost every part of big cities. People can get to where they want to go much faster. High-speed trains are another example of China’s wonderful transport system. Travelling between cities by high-speed train takes only a few hours, even for trips that used to take days. ③ Another great thing that stands out in China is the availability (可用性) of services. If my bike is broken and needs a repairman, or if I want to buy some daily things, I just need to make a phone call or tap on my smartphone. Since everything is available online, I no longer have to go far to the supermarket. Even late at night, I can get food sent to my door in just 30 minutes. It is one of the key reasons I have stayed in China for so long. ④ What’s more, China’s convenience doesn’t only lie in the availability of services, but also in their user-friendliness. For example, the apps that I use for travelling are easy to use, even for people who are not good at technology. Everything, including payment methods, is simple and direct. This makes it easy for everyone to get things done without difficulties. Even my 70-year-old grandma can use the apps to pay for things when she visits me. ⑤ The convenience in China has helped me get more things done. I can save a lot of time on daily tasks and use it to do more meaningful things. I think that with technological progress and the development of basic services, life in China will become more convenient in the future. 1．What made the writer feel surprised when he first came to China? A．The low price of public transport. B．The large number of people in big cities. C．The convenience of public transport. D．The beautiful landscapes in the countryside. 2．What does the underlined word “It” in Paragraph 3 mean? A．People can easily use different apps. B．People can get whatever they need online. C．People can go anywhere by high-speed train. D．People can quickly get broken things repaired. 3．Which of the following could be the writer of this text? A．Allen, an international student in Beijing for 4 years. B．Zhao Wei, a Chinese who has just returned from abroad. C．James, a foreigner who has had a one-week trip to China. D．Li Hua, a Shanghai student who is proud of Chinese culture. 4．What is the structure of the text? A．B．C． D． 【答案】1．C 2．B 3．A 4．D 【导语】本文是一篇说明文，作者以外国人视角，从公共交通、线上服务、软件易用性三方面介绍了在中国生活的便捷，并展望未来。 1．第二段原文：“The moment I came to this country...The public travel system, especially in big cities, is great”，说明作者初到中国时，对公共交通的便捷性感到惊喜。 2．第三段前文讲述：“Since everything is available online...I can get food sent to my door in just 30 minutes”，It指代前文“人们可以在线上获取所需一切”。 3．文章使用第一人称介绍在中国生活的体验，且提到“70‑year‑old grandma”，说明作者是长期在华的外国人，与“在北京留学4年的外国学生”相符合。 4．文章结构：①总起（中国生活便捷）→②③④分述（交通、线上服务、软件易用）→⑤总结（便捷带来的好处与未来展望），是总—分—总结构。 The chart below shows the changes in people’s daily life with the development of technology.

Now thousands of people have moved from distant villages to towns with better houses, schools and health care. Roads that once took days to travel now take minutes, and the Internet reaches homes that once had no electricity. The people of Nujiang still practice their traditions and customs even with great changes in the development of their area. Embroidery (刺绣), weaving (编织) and dance remain part of daily life. This connection of old and new is not accidental — it reflects an understanding that development does not mean abandoning traditions. In a Lisu village, it’s very common to see a woman weaving textiles (纺织品) using skills passed down from her ancestors. The patterns and styles reflect their history, beliefs and connection to the land. These textiles are a very important part of their traditions, worn during festivals and ceremonies. ▲ These cultural practices are not old things of the past but living traditions that continue to develop in today’s world. Tourism has become a main source of income (收入), with visitors drawn to Nujiang by its amazing natural views and lively culture. Local business owners have also found new ways to sell traditional handmade goods, creating jobs that both keep their special culture and provide income. As China continues to modernize, it is necessary to protect and improve the cultural values. It means progress doesn’t come at the cost of cultural values. Nujiang offers a clear example. It shows that protecting traditional culture is not just about looking back, but also about shaping a future that honors the past. 1．How does the writer begin the passage? A．By telling stories. B．By listing numbers. C．By describing reasons. D．By comparing differences. 2．What does the underlined word “abandoning” in Paragraph 2 probably mean? A．Caring about. B．Looking for. C．Giving up. D．Passing on. 3．Which of the following sentences can be put into ▲ in Paragraph 3? A．They refuse to accept any modern changes in their life. B．These old practices are not forgotten, but connected with modern life. C．Young people prefer to learn new skills rather than keep traditions. D．Most people think traditional culture is out of date. 4．What influence does tourism have on Nujiang? A．It helps create more job positions. B．It causes an increase in prices. C．It leads to the loss of traditions. D．It harms the local environment. 5．What is the main idea of the passage? A．Nujiang used to be one of China’s poorest areas. B．Traditional culture is very important to Nujiang people. C．Nujiang develops well while keeping its traditional culture. D．Tourism brings great changes to Nujiang. 【答案】1．D 2．C 3．B 4．A 5．C 【导语】本文介绍了云南怒江在居住、交通、网络等方面实现巨大发展，当地人民在现代化建设中依旧传承各类传统民俗文化，还依托自然与文化资源发展旅游业增收。文章借此表明，地区发展不必舍弃传统文化，二者可以共存共进。 1．文章第一段通过对比怒江过去“once one of China’s poorest areas”、“once had no electricity”和现在“Now thousands of people have moved from distant villages to towns with better houses, schools and health care.”的状况，突出了变化之大，因此作者是通过对比差异来开始文章的。 2．第二段“This connection of old and new is not accidental — it reflects an understanding that development does not mean abandoning traditions.”表明，尽管该地区发展巨大，人们仍然实践传统习俗，这说明发展并不意味着“放弃”传统。单词“abandoning”意为抛弃、放弃，与Giving up意思相近。 3．空格前“These textiles are a very important part of their traditions, worn during festivals and ceremonies.”描述了传统的编织技艺，空格后“These cultural practices are not old things of the past but living traditions that continue to develop in today’s world.”指出这些文化习俗是“当今世界继续发展的活传统”。选项B“这些古老习俗未被遗忘，而是与现代生活相连”能够承上启下，符合段落逻辑。 4．第四段内容“creating jobs that both keep their special culture and provide income”表明，旅游业为当地创造了就业机会。 5．全文主要讲述了怒江地区在实现现代化发展的同时，成功地保护并延续了传统文化。最后一段“It shows that protecting traditional culture is not just about looking back, but also about shaping a future that honors the past.”指出进步不以牺牲文化为代价，C选项最全面地概括了这一主旨。 Around 150 years ago, being in a dark period, China was weak and faced many challenges. During the late Qing Dynasty, the famous leader Li Hongzhang wanted to save the country. He believed China could become strong by learning from developed countries. So he sent many young officers and students to Germany. They studied science, high technology and machine building there. At that time, China was like a hard-working student. German industrial products were highly valued. German experts taught Chinese students scientific methods to use modern weapons and build steel factories. They studied day and night, hoping to bring useful skills back home. Germany was truly their teacher, showing the way forward. Fast to 2026, the world has seen a great change. China has developed quickly in science and technology. So a group of leaders from over 30 German companies visited China. They traveled to Hangzhou to visit a leading Chinese robot company. The German guests watched amazing robot performances. To their surprise, the robots could do many difficult movements like back flips, martial arts routines, and quick turns. Many of them were so excited that they were willing to stay here for learning China’s experience in AI, robots and so on. This shows a clear change. From a learner to a teacher, China has taken a historic step forward in some high-tech fields. 1．What did young officers and students study in Germany about 150 years ago? ① science    ② high technology    ③ AI and robots    ④ machine building A．①②④ B．②③④ C．①③④ 2．Why did the leaders from German companies visit China? A．Because they wanted to enjoy the West Lake in Hangzhou. B．Because they wanted to watch amazing robot performances.

A．build modern factories B．do difficult movements C．make industrial products 4．Which one shows the right relationship between the time from 1870s to 2026(x) and the development of China’s science (y) according to the passage? A． B． C． 5．What’s the best title for the passage? A．From a Learner to a Teacher B．Science and Technology C．A Teacher or a Worker 【答案】1．A 2．C 3．B 4．C 5．A 【导语】本文讲述了中国在科技领域从150年前向德国学习的“学生”，转变为如今在人工智能和机器人等高科技领域被德国企业学习的“老师”的历史性跨越。 1．根据第一段最后一句“They studied science, high technology and machine building there.”可知，年轻的军官和学生在德国学习的内容有科学、高科技和机器制造，并没有学习人工智能和机器人。 2．根据第三段“China has developed quickly in science and technology. So a group of leaders from over 30 German companies visited China.”可知，德国公司领导人访问中国是因为中国在科技方面发展迅速。 3．根据第四段“To their surprise, the robots could do many difficult movements like back flips, martial arts routines, and quick turns.”可知，中国机器人公司的机器人能做高难度动作。 4．文章讲述了中国从150年前的落后、需要向德国学习，到如今科技迅速发展、德国人来中国学习的转变。这表明从19世纪70年代到2026年，中国的科学发展水平是随着时间的推移不断上升的。图C呈现的是随时间推移不断上升的曲线，符合文意。 5．文章通过对比150年前中国派人去德国学习科技，和如今德国企业领导人来中国学习人工智能和机器人技术，展现了中国在科技领域的角色转变。最后一段“From a learner to a teacher, China has taken a historic step forward in some high-tech fields.”点明了文章主旨。因此，“From a Learner to a Teacher（从学习者到老师）”最适合作为文章标题。 学科网（北京）股份有限公司 $ Unit 1 The Changing World 单元话题阅读理解练习 单元话题：时代变迁 本资料共10篇专题训练，从上到下依次按照难度分为基础语篇巩固练和重难语篇提升练 基础语篇巩固练 聚焦基础，巩固自我 重难语篇提升练 专注提升，挑战自我 ◇考点 01 基础语篇巩固练 Fan Zhenxi is the Party Branch Secretary (党支部书记) of Zhoutaizi Village in Hebei Province.

Xiajiang Village in Zhejiang Province is a good example. It has turned from a quiet and poor place into a modern and lively one, especially in housing and travelling. In the past, villagers in Xiajiang Village lived in old houses made of wood and mud (泥). The walls were thin, so the houses were cold in winter and hot in summer. There were no clean toilets, and people had to carry water from a river far away every day. Life was hard and inconvenient. Now, with government support and more money from the growing economy, these old houses are gone. New houses stand in rows in Xiajiang Village, with bright rooms and clean yards. They use clean energy for lighting and heating, which helps reduce pollution. Villagers in Xiajiang Village now live comfortably and safely. Travelling in Xiajiang Village has improved greatly too. Years ago, the village only had narrow dirt roads. When it rained, the roads became dirty. Villagers walked or rode bikes to the town, which took several hours. Selling produce was difficult because of bad roads. Today, wide new roads connect Xiajiang Village to the city. Buses run four times a day, and many families in the village have their own cars. More tourists come to visit Xiajiang Village and local farmers can sell their fruit and vegetables to big cities quickly. New ways of travelling bring more jobs and money to Xiajiang Village. These changes in Xiajiang Village take place because of rural revitalization. It gives the village support and money. Economy provides enough money for building houses and roads, while technology makes life easier and smarter. Xiajiang Village is becoming richer and more beautiful.

Over the past few years, great changes have taken place in the countryside of Hainan Province, and Shenchong Village in Danzhou is a perfect example. Tourism has helped locals live better lives. For example, 56-year-old He Sanjie once made a living by fishing. Now he works as a guard in the village’s tourist area, where old volcanic rocks have been built into paths, theaters and nice homestays (民宿). Before tourism developed, Shenchong Village had 810 registered (登记的) people, but only about 100 lived there. Most villagers left for big cities. Now the empty stone houses have become warm and bright homestays. Roads are wider, and living conditions have improved greatly. He Sanjie says the busiest season lasts from spring to autumn. He can make over 50,000 yuan a year just from land rent (租金). “In winter, we can stay in warm houses and have free time. We couldn’t do this before. At that time, we only fished and hardly made enough money,” he adds. With the rise of tourism, the village has grown fast. In the first few months, around 40,000 visitors came. More young people are now returning from big cities to work in their hometown because they can look after their families and help build the village at the same time.

Nowadays, millions of Chinese leave the countryside to search for work in the cities. Among these is Zhong Wei, a 46-year-old husband and father. He has lived in Wenzhou for the last 13 years. With a hard job in a crayon factory, he doesn’t find much time to visit his hometown. “I used to return home at least once a year, but I haven’t been back for almost three years now. It’s a shame, but I just don’t have the time.” he says. Many people like Zhong Wei regard with great interest how their hometowns have changed. Perhaps large hospitals and new roads have appeared. In many places, the government has also built new schools and sent teachers from the cities to help. “I noticed that’s true of my hometown,” adds Zhong Wei. “Children have learned to read and count at my old primary school since the mid-20th century. But now the buildings are really old. I hear they’re going to build a new school there.” Zhong Wei thinks such developments are good, and he also knows that his hometown cannot always stay the same. According to Zhong Wei, however, some things will never change. “In my hometown, there was a big old tree opposite the school. It is still there and has become quite a symbol of the place. Most of the children in my time liked to play together under that big tree, especially during the summer holidays. It was such a happy childhood. Our hometown has left many soft and sweet memories in our hearts.” 1．Why hasn’t Zhong Wei been back to his hometown for almost three years? A．Because he doesn’t miss his hometown at all.

D．Everything in his hometown has changed. “As a new Shenzhener, being led to check out the history of my city is really a wonderful experience,” said a participant in her online blog, after she took part in a cultural tour led by Mary Ann O’Donnell, an American anthropologist (人类学家) who has been based in Shenzhen since the 1990s. The Shuiwei tour, organized by Handshake 302, a public art organization, was one of a series of tours that will take visitors to a total of seven places of cultural and historical importance in Shenzhen. Take Metro Line 4 or 7, get off at Fumin Station, walk a few steps, and you will get to the heart of Shuiwei. “What’s important is not what did or did not happen, but how the stories we tell become history, and how we use the history to shape our identities,” said O’Donnell. Along the years, people in Shuiwei made a living by fishing and producing sea salt. However, the practical influence of “water” gradually fell off. Around the 1980s, villagers travelled to and from Hong Kong by boat to buy daily necessities or unusual objects and resell them in Shenzhen. Meanwhile, village renovation and industrialization (工业化) turned Shuiwei into a landlocked region. The village soon changed its livelihood from fishing and agriculture (农业) to manufacturing (制造业) and real estate (房地产业). Handshake buildings are everywhere. The rock museum in the village, which exhibits hundreds of valuable rocks collected from all over the world, also shows the transition from “water” to “land” in Shuiwei’s cultural geography, according to O’Donnell. 1．How many metro lines which can take visitors to the heart of Shuiwei? A．2. B．3. C．4. D．7. 2．What did the writer mention to show the importance of “water” in people’s lives in Shuiwei? A．Hand-shake buildings. B．The rock museum. C．Fishing and producing sea salt. D．Manufacturing and real estate. 3．What is O’Donnell’s attitude towards history according to her words? A．History is about recording true facts exactly. B．History helps people build their sense of identity. C．History should be kept unchanged forever. D．History is less important than modern life. 4．What does the underlined word “transition” in the last paragraph probably mean? A．价值 B．转变 C．渊源 D．典故 5．What is the author’s main purpose in writing this passage? A．To call on people to protect traditional fishing culture. B．To explain why Shuiwei has so many hand-shake buildings. C．To introduce Shuiwei's historical changes and cultural meaning. D．To teach readers how to visit places of interest in Shenzhen. ① Living in China has made me realize how convenient life can be. It is much better than I ever thought, and it has completely changed my way of life. ② The moment I came to this country, a wave of pleasant surprise washed over me. The public travel system, especially in big cities, is great. The underground networks cover almost every part of big cities. People can get to where they want to go much faster. High-speed trains are another example of China’s wonderful transport system. Travelling between cities by high-speed train takes only a few hours, even for trips that used to take days. ③ Another great thing that stands out in China is the availability (可用性) of services. If my bike is broken and needs a repairman, or if I want to buy some daily things, I just need to make a phone call or tap on my smartphone. Since everything is available online, I no longer have to go far to the supermarket. Even late at night, I can get food sent to my door in just 30 minutes. It is one of the key reasons I have stayed in China for so long. ④ What’s more, China’s convenience doesn’t only lie in the availability of services, but also in their user-friendliness. For example, the apps that I use for travelling are easy to use, even for people who are not good at technology. Everything, including payment methods, is simple and direct. This makes it easy for everyone to get things done without difficulties. Even my 70-year-old grandma can use the apps to pay for things when she visits me. ⑤ The convenience in China has helped me get more things done. I can save a lot of time on daily tasks and use it to do more meaningful things. I think that with technological progress and the development of basic services, life in China will become more convenient in the future. 1．What made the writer feel surprised when he first came to China? A．The low price of public transport. B．The large number of people in big cities. C．The convenience of public transport.

Now thousands of people have moved from distant villages to towns with better houses, schools and health care. Roads that once took days to travel now take minutes, and the Internet reaches homes that once had no electricity. The people of Nujiang still practice their traditions and customs even with great changes in the development of their area. Embroidery (刺绣), weaving (编织) and dance remain part of daily life. This connection of old and new is not accidental — it reflects an understanding that development does not mean abandoning traditions. In a Lisu village, it’s very common to see a woman weaving textiles (纺织品) using skills passed down from her ancestors. The patterns and styles reflect their history, beliefs and connection to the land. These textiles are a very important part of their traditions, worn during festivals and ceremonies. ▲ These cultural practices are not old things of the past but living traditions that continue to develop in today’s world. Tourism has become a main source of income (收入), with visitors drawn to Nujiang by its amazing natural views and lively culture. Local business owners have also found new ways to sell traditional handmade goods, creating jobs that both keep their special culture and provide income. As China continues to modernize, it is necessary to protect and improve the cultural values. It means progress doesn’t come at the cost of cultural values. Nujiang offers a clear example. It shows that protecting traditional culture is not just about looking back, but also about shaping a future that honors the past. 1．How does the writer begin the passage? A．By telling stories. B．By listing numbers. C．By describing reasons. D．By comparing differences. 2．What does the underlined word “abandoning” in Paragraph 2 probably mean? A．Caring about. B．Looking for. C．Giving up.
