But you may not know that this river wasn't always as clean as it is today. Ten years ago, the river was heavily polluted. Hotels and restaurants along the banks poured waste water directly into the river. Tourist boats left oil and rubbish behind. The number of fish dropped sharply, and local people stopped swimming in the river. （漓江桂林市区段的蚂蟥洲对比图片） In 2016, the local government started a clean-up project. Hotels and restaurants were required to install wastewater treatment systems. Tourist boats were replaced with electric ones that produce no pollution. Along the riverbank, trees were planted and walking paths were built. The results have been encouraging. By 2024, the water quality of the Lijiang River reached Grade II—the second highest level. Fish have returned in large numbers, and locals swim in the river again. "Twenty years ago, the river was beautiful and clean," said Mr. Chen, a 55-year-old boatman who has worked on the river for more than thirty years. "Then it got dirty. But now it's coming back. I'm really happy about that." The Lijiang River is not just a tourist attraction—it is also the lifeblood of the local people. 26. Where is the Lijiang River? A. In Yangshuo, Guilin. B. In Nanning, Guangxi. C. In Guizhou Province. D. In Yunnan Province. 27. What was the Lijiang River like ten years ago? A. It was clean and beautiful. B. It became a tourist attraction. C. It was connected to the Internet. D. It was heavily polluted. 28. What did the local government do to protect the river? ① They replaced old boats. ② They built new hotels. ③ They required wastewater treatment. ④ They planted trees. A. ①②③ B. ①③④ C. ②③④ D. ①②④ 29. What does Mr. Chen say about the river? A. It was always clean. B. He is unhappy about the changes. C. It is getting better now. D. He has worked on the river for 20 years. 30. What does the writer want to tell us? A. The Lijiang River is a good place for tourists. B. The local government should do more for the river. C. A polluted river can be brought back to life. D. Fishing in the Lijiang River should be stopped. B In the past, villagers in remote areas had to walk for hours to sell their produce at local markets. Today, thanks to better roads and Internet access, many rural areas have been connected to the outside world. This has given rise to a new kind of villager: the "digital villager." Take Xiaowang Village in Yunnan as an example. Several years ago, it was a poor mountain village with no modern technology. In 2021, the village got high-speed fiber-optic Internet. Since then, things have changed greatly. Villagers started livestreaming to sell their fruits, tea and handmade crafts to customers across the country. They also use online platforms to buy goods at lower prices. Li Qiang, a young man who returned to the village in 2022, said, "I used to work in a factory in Shenzhen. Now I earn even more money by selling our local products online. The Internet has opened up a whole new world for us." Digital tools have also improved education and healthcare. Students can now take online lessons from experienced teachers in big cities. The village clinic uses telemedicine to connect to city hospitals. According to official data, the average income of rural residents increased from 17,131 yuan in 2020 to 24,456 yuan in 2025. Rural tourism and e-commerce are growing fast. However, challenges still exist. Some elderly villagers have trouble using smartphones, so the government has set up training programs to help them. 31. What does the term "digital villagers" refer to? A. Villagers who have moved to cities. B. Villagers who make use of digital technology. C. Villagers who grow digital products. D. Villagers who live in big cities. 32. When did Xiaowang Village get high-speed Internet? A. In 2021. B. In 2022. C. In 2023. D. In 2025. 33. Why did Li Qiang return to his village? A. He lost his job in the city. B. He missed his family. C. He wanted to become a teacher. D. He could earn more money online. 34. How does the village clinic benefit from telemedicine? A. It gets more local doctors. B. It can ask city hospitals for advice. C. It reduces the cost of medicine. D. It provides free healthcare. 35. What problem does the passage mention? A. The Internet signal is too weak. B. Students dislike online classes. C. Some elderly people have difficulty using smartphones. D. Local products do not sell well. C The Saihanba Mechanized Forest Farm is often called a "green miracle." What makes it so special? Saihanba, which means "beautiful highlands" in Mongolian, lies in Hebei Province. In the 1950s, it was a barren land with few trees. Sandstorms were frequent, and the soil was poor for farming. Dust from Saihanba often blew all the way to Beijing, more than 200 kilometers away. In 1962, a group of 369 young people arrived. They came to plant trees. The conditions were extremely harsh. Winters lasted more than six months, and temperatures could drop to -40°C. They had no electricity and no clean water. Many gave up and left, but some stayed. Among those who stayed was Wang Shanghai. He came with his family in 1962 and worked in the forest until his death in 1989. He once said, "The first few years were very hard. We planted thousands of trees, but most of them died. We had to learn from our failures and try again." They did succeed. Over the next decades, they planted more than 700 million trees across nearly 1,000 square kilometers. Today, Saihanba is a vast green forest with more than 600 species of plants. Animals have returned. The sandstorms that once troubled Beijing have become much less frequent. In 2017, the United Nations recognized Saihanba with the "Champions of the Earth" award. The story of Saihanba shows that persistence and hard work can bring a damaged environment back to life. 36. Where is Saihanba? A. In Inner Mongolia. B. In Yunnan. C. In Guizhou. D. In Hebei Province. 37. What was Saihanba like in the 1950s? A. It was covered with thick forest. B. It was a beautiful highland. C. It was a barren land with few trees. D. It was a famous tourist attraction. 38. Why did Wang Shanghai say the first few years were hard? A.Most of the trees they planted died. B. The weather was too hot. C. They had no tools. D. The government did not support them. 39. What have the tree planters achieved? A. Saihanba has become a desert. B. Over 700 million trees have been planted. C. All the animals have disappeared. D. No sandstorms happen in Beijing anymore. 40. What does the story of Saihanba teach us? A. Planting trees is an easy job. B. Determination can restore a damaged environment. C. The government should protect the environment. D. Young people should leave the countryside. D 阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 For decades, young people in rural China moved to cities for better jobs. 41______ Many villages were left with only the elderly. But now, a new trend is reversing this flow. Li Ming, 28, left his village in Sichuan for a factory job in Guangzhou in 2018. 42______ In 2023, he returned. "I used to think only cities offered chances," he says. "Now, our village has high-speed Internet and a new road. I can sell our local products online and make a good living." Li is not alone. Across China, thousands of young people are going back. They are starting guesthouses, opening online shops, and creating new businesses.43_____ What has made this change possible? Better roads and railways, high-speed Internet, and government support have all helped. Villages are no longer as isolated as they used to be. However, this change comes with challenges. Some villagers worry that too much tourism might harm the natural environment. 44_____ The government is working on plans to balance development with protection. 45_____ But if done wisely, it can bring new life to the countryside while keeping its traditional character.

The town used to be poor and cut off from the outside world. Most young people had left to find work in big cities, and the main road was so bumpy that it took three hours to drive to the nearest city. The railway changed everything. Travel time to the nearest city was cut from three hours to just 40 minutes. Tourists began to come for the town's famous hot springs and beautiful mountains. Local villagers opened guesthouses and restaurants. Farmers started selling their fruits and vegetables directly to city markets through an online platform. By 2023, the town had a new school, a hospital, and several factories. The number of tourists had grown from 2,000 a year to more than 50,000. Many young people who had left returned to start businesses. "I used to work in a factory in Shenzhen," said 30-year-old Huang Wei. "Now I run a guesthouse with my wife. We make more money here and we can see our parents every day." However, some people worry about the rapid changes. "We welcome the development," said the town head, "but we also need to protect our culture and environment." 46. When was the high-speed railway station built in the town? 47. How long did it take to drive to the nearest city before the railway was built? 48. How has the number of tourists changed by 2023? 49. What does Huang Wei do now? 50.

You asked me about the changes in China in your last letter.

Yours sincerely, Li Hua 参考答案及解析 一、单项选择（本大题共10小题，每小题1分，共10分） 1. C【解析】句中的"since I left five years ago"是现在完成时的标志，表示"自从五年前我离开以来"，强调过去的动作对现在造成的影响（家乡现在完全不同了）。A为一般现在时，B为一般过去时，D为一般将来时，均不符合语境。 2. A【解析】本题同时考查两个结构：第一空"used to live"表示"过去住在"，与"but now"形成对比；第二空"is used to"表示"习惯于"，后接动名词。不少学生会误选B或D，主要是混淆了"used to do"和"be used to doing"的用法。B、C、D结构均不正确。 3. D【解析】bridge与complete之间为被动关系，且"last year"表示过去的具体时间，所以用一般过去时的被动语态was completed。第二空表示"已经减少了"出行时间，强调对现在的影响，用现在完成时has reduced。 4. B【解析】"Have you ever been to..."表示"你曾经去过……吗？"（已回来），ever用于完成时态。答语中的"last Sunday"是过去的具体时间，用一般过去时went。干扰项C中"have gone"表示"去了未回"，与last Sunday矛盾。 5. C【解析】"over the past few years"（在过去的几年里）是现在完成时的典型标志，表示近年来反复发生的动作。A、B、D时态均不符合。 6. D【解析】temple与build之间为被动关系，"in the Tang Dynasty"表示过去的时间点，用一般过去时被动was built。第二空描述"至今仍在使用"的现状，用一般现在时is。 7. B【解析】"For about two months"表示一段时间，用How long提问。How soon问"多久以后"，How often问"频率"，How far问"距离"，均不符合。 8. C【解析】"used to do"表示"过去常常做某事而现在不再做了"，符合"过去写信联系，现在用微信"的对比语境。A项"不得不"、B项"过去不得不"、D项"习惯于"均不符合。 9. A【解析】"since + 一般过去时从句"引导时间状语时，主句用现在完成时，所以第一空填has become。plant与build之间为被动关系，且"waste treatment plant"是过去建的，用一般过去时被动was built。不少学生看到"since"就只想到主句用现在完成时，却忽略了从句也必须用一般过去时的被动语态。 10. C【解析】"I couldn't agree more"表示"我完全同意"，用于对对方观点表示强烈赞同，与后文"I hardly ever carry cash now"形成呼应。A项"不是那样"、B项"我不这么认为"、D项"好主意"（用于回应建议）均不符合对话语境。 二、补全对话（本大题共5小题，每小题2分，共10分） 11. B【解析】下文"I spent the whole summer vacation there"中的"there"指代"hometown"，说明李伟刚从家乡回来，故选B。 12. C【解析】下文"Now it's wide and smooth"与过去形成对比，空白处应描述道路过去的状况——又窄又颠簸，故选C。 13. A【解析】下文"Yes, quite a few young people have returned"是对一般疑问句的肯定回答，内容涉及年轻人返乡，故选A。 14. E【解析】下文"Absolutely!"是对一般疑问句的强烈肯定回答，内容涉及对变化的评价，故选E。 15. D【解析】下文"Of course! You're welcome anytime"表明对方爽快地答应了请求，空白处应为请求对方带自己参观，故选D。 三、完形填空（本大题共10小题，每小题1.5分，共15分） 16. B【解析】depend on表示"依赖、依靠"，后文提到"唯一的土路极其崎岖，走到最近的集市要近三个小时"，说明村民靠小农场维持生计。A项worked on虽可与on搭配，但只表示"在农场干活"，不能体现"以此为生"的依赖关系；C项waited on、D项turned on与small farms搭配后语义不通。 17. D【解析】"It took + 时间 + to do"为固定句型，表示"做某事花了多长时间"。spend的主语是人，cost的主语是物，pay的主语是人且常与for搭配。 18. B【解析】Some表示"其中一些"，与下文"than they used to earn in a whole year"构成比较——"其中一些人在一个月内挣的比过去一整年都多"。All过于绝对，None和Neither表示否定，均不符合文意。 19. C【解析】itself是反身代词，表示"村庄自身"，强调主语本身实施了建造行为。it为主格，its为形容词性物主代词，it's为it is的缩写。 20. A【解析】which引导非限制性定语从句，指代前面整个分句"村里诊所可以通过互联网得到城市医生的建议"这件事。that不能引导非限制性定语从句，这是初中阶段必须掌握的语法点。 21. A【解析】描述过去的事实（大学毕业后去了大城市工作），用一般过去时went。has gone强调"去了未回"，与后文"In 2022, she came back"矛盾。 22. B【解析】不定式to enjoy作目的状语，表示"为了欣赏"，解释游客前来的原因。 23. C【解析】has increased表示"已经增长了"，强调从过去（2021年互联网进村）到现在（2026年）已经完成并产生结果。时间状语"By 2026"提示到目前已经完成，用现在完成时而非一般过去时。 24. D【解析】have changed表示"已经改变了"，主语changes为复数。强调变化已经发生并对现在产生影响。will change表示"将要改变"，不符合语境。 25. B【解析】what we have achieved作介词of的宾语，意为"我们所取得的成就"。what在从句中作achieved的宾语。that引导名词性从句时在从句中不充当成分，which引导定语从句需要有先行词，how在从句中作状语。 四、阅读理解（本大题共20小题，每小题1.5分，共30分） A篇 26. A【解析】根据第一段第一句"If you have visited Yangshuo in Guilin, you must have seen the Lijiang River"可知，漓江位于桂林阳朔。 27. D【解析】根据第二段第一句"Ten years ago, the river was heavily polluted"可知，十年前漓江污染严重。 28. B【解析】文章提到了三项措施：①旧船被电动船替代，③要求安装污水处理系统，④植树。②"建新酒店"文中未提及，故排除含②的A、C、D项。 29. C【解析】陈先生说"现在它正在恢复"，表达的是河流在变好的意思。A项"一直很干净"与事实不符，B项"对变化不满意"与文意相反，D项"工作了20年"与原文"more than thirty years"不符。 30. C【解析】全文讲述了漓江从污染到恢复的过程，写作目的是说明受污染的河流可以被拯救。A项只是文中提及的一个事实而非主旨，B项"政府应该做得更多"文中未体现，D项"应该禁止捕鱼"文中未提及。 B篇 31. B【解析】根据第一段最后一句"This has given rise to a new kind of villager: the 'digital villager.'"及全文内容可知，"数字村民"指利用数字技术的村民。A项搬到城市的村民、C项种植数字产品的村民、D项住在大城市的村民，均曲解了文意。 32. A【解析】根据第二段第二句"In 2021, the village got high-speed fiber-optic Internet"可知。 33. D【解析】根据第三段李强的话"Now I earn even more money by selling our local products online"可知，他返乡是因为在线销售能挣更多钱。 34. B【解析】根据第四段最后一句"The village clinic uses telemedicine to connect to city hospitals"可知，远程医疗使村诊所可以联系城市医院寻求建议。A项"获得更多本地医生"、C项"降低药费"、D项"提供免费医疗"文中均未提及。 35. C【解析】根据最后一段"Some elderly villagers have trouble using smartphones"可知，部分老年人使用智能手机有困难。A项"网络信号太弱"、B项"学生不喜欢网课"、D项"本地产品不好卖"文中均未提及。 C篇 36. D【解析】根据第二段第一句"Saihanba...lies in Hebei Province"可知，塞罕坝位于河北省。 37. C【解析】根据第二段第二句"In the 1950s, it was a barren land with few trees"可知，20世纪50年代塞罕坝是一片荒地，几乎没有树。 38. A【解析】根据第四段王尚海的话"We planted thousands of trees, but most of them died"可知，最初的困难是种下的树大部分死了。 39. B【解析】根据第五段第一句"they planted more than 700 million trees"可知，他们种下了超过7亿棵树。A项"变成沙漠"、C项"所有动物都消失了"与事实相反，D项"北京不再有沙尘暴"过于绝对（原文是"much less frequent"）。 40. B【解析】全文讲述了塞罕坝从荒漠变为森林的故事，主旨是决心和坚持可以恢复受损的环境。A项"植树是件容易的事"与文中艰苦条件相反，C项"政府应该保护环境"、D项"年轻人应该离开农村"均不是文章主旨。 D篇（七选五） 41. A【解析】前一句说"几十年来，农村的年轻人进城寻找更好的工作机会"，后一句说"许多村庄只剩下老人"，中间应填一个解释原因的句子——"他们中的大多数人再也没有回来"，故选A。 42. C【解析】前一句说李明2018年离开村子去广州，后一句说2023年他回来了。中间应填他在广州工作期间的情况——工作了五年但觉得缺了什么。 43. D【解析】前一句列举了返乡年轻人正在做的事（开民宿、开网店、创业），后一句应总结这些行为带来的效果——"这些年轻人正在给村庄带来新的活力"。 44. F【解析】前一句说“有人担心太多旅游业破坏环境”，后一句说“政府在制定平衡发展与保护的方案”，中间需要说明旅游业发展的现状——“他们也在把村庄变成旅游目的地”。选F既承接前文“旅游业”，又为后文“政府制定方案”提供了背景。 45. B【解析】最后一段总结前文：发展对农村是机遇，但要稳妥推进。B项"这是农村地区的大好机会"最符合总结段的首句位置。 干扰项排查：E"大多数年轻人宁愿留在村里"与全文主旨（年轻人回流）相反，属于明显错误选项；G"政府停止支持农村发展"与文中"government support"相矛盾，且与主旨相反。 五、任务型阅读（本大题共5小题，每小题2分，共10分） 46. In 2019.【解析】根据第一段第一句"In 2019, a new high-speed railway station was built in a small town in Guangxi". 47. Three hours.【解析】根据第一段最后一句"it took three hours to drive to the nearest city" 48.

You asked me about the changes in China in your last letter. I'm happy to share some with you. I live in a small city in Guangxi, and great changes have taken place here in the past few years. The roads used to be narrow and bumpy, but now they are wide and smooth. A new railway station was built last year, so traveling has become much faster and easier. People also pay more attention to the environment now. The river near my home was once dirty and smelly, but now it is clean again, and you can even see fish swimming in it. These changes have made our lives more convenient and comfortable. My parents no longer worry about the traffic, and I often go fishing with my grandpa by the river on weekends. I feel very proud of my hometown. I believe it will become even better in the future. I hope you can visit China one day and see these changes for yourself! Yours sincerely, Li Hua 学科网（北京）股份有限公司 $
