Plastic pollution is everywhere on the river surface, and overfishing has broken the balance of its ecosystem. It’s time for us to take action to protect it. First, let’s start with personal actions. We should reduce the use of plastic products, such as bringing reusable bags when shopping and refusing disposable tableware. Every small step can cut down plastic waste entering the river. Second, we can organize campus activities. Planting trees along both sides of the Yangtze River can prevent soil erosion and provide a better living environment for aquatic organisms. We can also hold river-cleaning activities on weekends to collect rubbish by the river. Third, we can use technology to help. With AI intelligent monitoring systems, we can track the situation of plastic pollution and illegal fishing in real time. This can help relevant departments take timely measures to stop harmful behaviors. Remember: every little thing we do brings us closer to a green future.

Yang talked excitedly about finding such treasure in January 2022. “We got over 2,450 kilograms of large yellow croakers (大黄鱼) in a net yesterday,” Yang said. “The heaviest one weighed more than two kilograms,” said Lin Haiping, the owner of the fishing boat on which Yang works. “I’ve been fishing for 28 years but never caught so many large yellow croakers of this size before,” Lin added. Fang Yue, an engineer working in Xiangshan, said, “It’s the first time that fishermen have caught so many large yellow croakers in the East China Sea in over 30 years.” There used to be many large yellow croakers in the East China Sea, but the number has dropped for about 45 years because of overfishing. In 1979, Zhejiang started a yearly seasonal ban (禁止) on fishing. Later in 1995, other areas through the whole country followed its example. Fang said that the number of large yellow croakers has become larger because of the sea protection efforts (努力). Fishermen from Xiangshan have made great efforts, too. In 2000, 21 fishermen in Xiangshan set up China’s first volunteer organization to better protect the sea around the world. Today, more than 10,000 people have joined the organization. In 2002, three fishermen from the county wrote to Kofi Annan, calling on people around the world to protect the sea together. Huang Genbao, head of the Xiangshan Fishing Association, said that although harvesting more than 1,000 kg of large yellow croakers doesn’t happen often, he hoped that sea protection would go on and more fishermen would have more fish in the future. 16．How does the writer start the passage? A．By asking a question. B．By giving an example. C．By telling a joke. D．By introducing (介绍) a fisherman. 17．What does the underlined word “it” in the first paragraph refer to (指代)? A．The treasure. B．The harvest. C．The sea. D．The heaviest fish. 18．What is the correct order to show the efforts made in sea protection? ①A yearly seasonal ban on fishing was started in Zhejiang. ②Other areas in our country followed Zhejiang’s example. ③Three fishermen from the county wrote to Kofi Annan, calling on people around the world to protect the sea together. ④To protect the sea around the world, twenty-one fishermen in Xiangshan set up a volunteer organization. A．②①③④ B．①②④③ C．②④③① D．①③②④ 19．What can we learn from the passage? A．Both Yang Tiansheng and Fang Yue are fishermen in Xiangshan County. B．Fishermen like Lin Haiping caught many large yellow croakers in the East China Sea. C．The Zhejiang government set up China’s first volunteer organization to protect the sea. D．Harvesting more than 1,000 kg of large yellow croakers often happens in Zhejiang. 20．Which could be the best title for the passage? A．Harvest of large yellow croakers. B．China’s first volunteer organization. C．Yellow croakers, a local treasure. D．Sea protection works well in Zhejiang. 16．B 17．C 18．B 19．B 20．D 【导语】本文主要讲述了浙江渔民在海上保护方面的努力。 16．推理判断题。根据“For fisherman Yang Tiansheng in Xiangshan Country (县), Zhejiang Province, the sea will always be filled with treasure, if people protect it well and harvest the fish in a scientific way. Yang talked excitedly about finding such treasure in January 2022.”可知，本文以杨天生的捕鱼例子开始叙事。故选B。 17．词句猜测题。根据“the sea will always be filled with treasure, if people protect it well and harvest the fish in a scientific way”可知，如果人们保护好大海，科学捕捞鱼类，大海将永远充满宝藏。it指the sea“大海”。故选C。 18．推理判断题。根据“In 1979, Zhejiang started a yearly seasonal ban (禁止) on fishing. Later in 1995, other areas through the whole country followed its example.”可知，1979年，浙江开始实施每年的季节性禁渔期，之后我国其他地区也效仿浙江。即①②；根据“Fishermen from Xiangshan have made great efforts, too. In 2000, 21 fishermen in Xiangshan set up China’s first volunteer organization to better protect the sea around the world. Today, more than 10,000 people have joined the organization. In 2002, three fishermen from the county wrote to Kofi Annan, calling on people around the world to protect the sea together.”可知，2000年21名渔民成立第一个志愿者组织，今天超过1万人在组织里，之后三名渔民号召人们共同保护海洋，即④③。顺序是①②④③。故选B。 19．推理判断题。根据“‘We got over 2,450 kilograms of large yellow croakers (大黄鱼) in a net yesterday,’ Yang said.”“It’s the first time that fishermen have caught so many large yellow croakers in the East China Sea in over 30 years.”可知，像林海平这样的渔民在东海捕获了许多大黄鱼。故选B。 20．最佳标题题。本文主要讲述了浙江渔民在海上保护方面的努力。D选项“浙江的海洋保护工作做得很好”可作为文章标题。故选D。 C Rat and Mole are at home all day.

Mole is in the Wild Wood!” he puts on his coat and put a gun in his pocket. He goes along the path to the Wild Wood. He sees the strange faces with sharp teeth. But they see Rat’s gun, and go away. Rat calls and calls, “Mole, where are you? It’s me - Rat.” At last, Mole answers. “Rat, I’m here! In the tree! I am very frightened!” he says in a little voice. ‘‘Don’t worry, Mole,” says Rat, “Let’s go home now!” But Mole is very tired. He wants to sleep, so Rat sits and waits. While Mole is sleeping, it begins to snow. The snow is white and it covers all the paths. Later, Mole wakes up. Then the two friends set off through the white woods. Everything is different with the snow and soon Rat and Mole are lost. They walk for hours but they cannot find the way home. They are tired, and cold, and hungry. Suddenly, Rat sees a sign in the snow. The sign says, “Mr Badger”. “It’s Badger’s front door,” says Rat. He is very excited. They ring the doorbell. “Who is it?” calls Badger. ‘‘Oh, Badger,” cries Rat. “It’s me, Rat, and my friend Mole, and we are lost in the snow.” 21．What can we learn from Paragraph 2?

The faces have sharp teeth. He hears strange noises and he is afraid” 鼹鼠看到森林里奇怪的小脸，脸有锋利的牙齿，他听到奇怪的吵闹声，他很害怕。可知他在森林里碰到了很多困难。故选C。 22．细节理解题。根据第三段“When Rat wakes up at home, he calls, ‘Mole, Mole’”当老鼠在家醒过来，大叫“鼹鼠”，可知他在寻找鼹鼠。故选A。 23．细节理解题。根据第六段“While Mole is sleeping, it begins to snow”当鼹鼠睡觉的时候，开始下雪。故选B。 24．推理判断题。根据第一段“Mole is bored“鼹鼠在家感觉很无聊。根据第二段“He hears strange noises”鼹鼠听到一些奇怪的吵闹声。根据第四段“Rat, I’m here! In the tree”鼹鼠很开心在树林里见到老鼠，根据第七段“ Rat and Mole are lost”鼹鼠和老鼠在树林里迷路了。正确的顺序是②①④③。故选A。 25．推理判断题。根据最后一段“He is very excited ”及“It’s me, Rat, and my friend Mole, and we are lost in the snow”可知老鼠看到獾的房子很兴奋，他告诉獾他和鼬鼠在雪里迷路了，可知接下来讲述獾让他们进房间。C选项“獾叫他们进来”符合。故选C 。 三、信息还原 (本大题共5小题，每小题2分，共10分) 阅读下面短文，从短文后所给的7个选项中选出5个能填入短文空白处的最佳选项，使短文通顺、连贯，意思完整。 Have you ever stayed in a hotel? Most Chinese hotels often provide guests (客人) with things like disposable (一次性的) toothbrushes, toothpaste, shampoo and slippers. 26 But, if you travel to Beijing, remember to bring your own things. Starting from June, some hotels in Beijing will no longer provide guests with these disposables. 27 Many disposable things are made of plastic (塑料). People throw them away after only using them once. 28 Do you know, one Chinese person makes as much as 400 kg of waste a year! Most of that waste comes from disposable things. In Beijing, people throw away about 19,000 tons of plastic bags and 1,320 tons of plastic lunch bowls every year! Plastic can take between 100 and 400 years to break down. So the less plastic we throw out, the better. 29 Back at home and school, you can also do something to make our world a better place. Try to do these things in your daily life: Use cloth shopping bags. Not plastic ones. After using a plastic bag, wash it out and let it dry. 30 Do not use paper cups. At your school lining room, use your own bowl and chopsticks instead of disposable ones. To protect our environment and our home, it is very necessary and important for us to save natural resources. A．It is a waste of natural resources and is very bad for the environment. B．Many guests like the idea because they don’t have to bring their own. C．Here are some ideas for you to live a green life. D．They want to ask people to use disposable things less. E．Then you can use it over and over again. F．So, wherever you travel, bring your own things and use them again and again. G．What should we do to save the earth? 26．B 27．D 28．A 29．F 30．E 【导语】本文主要讲述了北京的宾馆为了环保不再向客人提供一次性的生活用品，作者倡导我们在家也可以做一些环保的事情，比如用布购物袋，不再用纸杯等。 26．根据上文“Most Chinese hotels often provide guests (客人) with things like disposable (一次性的) toothbrushes, toothpaste, shampoo and slippers.”可知，很多中国宾馆经常向客人提供一些一次性的牙刷，牙具，洗发水和拖鞋，这样给客人带来便利。选项B“许多客人喜欢这个想法，因为他们不必携带自己的东西。”符合语境。故选B。 27．根据上文“Starting from June, some hotels in Beijing will no longer provide guests with these disposables.”和下文“Many disposable things are made of plastic (塑料).”可知，从6月份开始，北京的一些宾馆不再向客人提供这些一次性的东西，很多一次性的东西是塑料做的。选项D“他们想要让人们少用一次性东西。”符合语境。故选D。 28．根据上文“People throw them away after only using them once.”可知，人们只用了一次就把它们扔了，选项A“这是资源的浪费并且对环境很不好。”符合语境。故选A。 29．根据上文“So the less plastic we throw out, the better.”可知，我们扔的垃圾越少，越好。选项F“所以无论你去哪里旅游，带上自己的东西并重复使用。”符合语境，故选F。 30．根据上文“After using a plastic bag, wash it out and let it dry.”可知，在用完垃圾袋后，洗干净然后把它弄干，说明可以多次重复使用。选项E“然后你可以一遍又一遍地使用它。”符合语境，故选E。 四、词汇运用 (本大题共10小题，每小题1分，共10分) （A）根据句意和汉语注释，写出单词的正确形式。 31．One of the ________ (原因) of family problems is poor communication between parents and children. 32．If we drop litter in a public place, we’ll be ________ (罚款) by the police. 33．Learning to ________ (控制) your anger is important for growing up. 34．The idea that enough sleep helps you think better is ________ (广泛地) accepted now. 35．Nowadays, ________ (电子的) books are easier to carry around than traditional paper books. 31．causes 【详解】句意：家庭问题的原因之一，是父母与子女之间缺乏良好的沟通。根据“poor communication between parents and children”可知，父母与子女之间缺乏良好的沟通，是造成家庭问题的原因之一，cause表示“原因”，根据“one of the…”可知，这是固定短语表示“……之一”，空格处要用复数名词。故填causes。 32．fined 【详解】句意：如果我们在公共场所乱扔垃圾，就会被警察罚款。 “罚款”为fine，此处应用过去分词为fined，与will be构成一般将来时的被动语态。 33．control 【详解】句意：学会控制你的愤怒对成长很重要。control“控制”是动词，learn to do sth.“学会做某事”是固定搭配，to后跟动词原形control。 34．widely 【详解】句意：充足睡眠有助于更好思考的观点现在被广泛接受。空处修饰动词accepted，需用副词形式，“广泛地”对应的英文是widely。 35．electronic 【详解】句意：如今，电子书比传统纸质书更容易携带。空格处修饰名词books，需用形容词，“电子的”对应的英文单词是electronic。 （B） 根据句意，写出括号内所给单词的适当形式。 36．Animals don’t need ________ (clean) water and food. 37．By pulling together, we ________ solved the problem.

Perhaps the driver ________ (make) a telephone call to others. 48．He ________ (shake) the bottle hard to see if there was any water inside. 49．The story ________ (write) by Hans Christian Andersen is still popular today. 50．Can you imagine what our life ________ (be) like in twenty years? 41．is given 【详解】句意：如果明天再给这个男孩一次机会，他会做得更好。句子是if引导的条件状语从句，从句用一般现在时；从句主语“the boy”和谓语动词“give”之间是被动关系，此处用一般现在时的被动语态，其结构为“is/am/are+done”，主语“the boy”是第三人称单数，所以be动词用is，“give”的过去分词“given”。故填is given。 42．sell 【详解】句意：露易丝·格丽克写的书很畅销，因为她是诺贝尔文学奖得主。根据“...well because she is...”可知，描述客观事实，用一般现在时；且“sell well”为固定搭配，意为“畅销”，主动形式表示被动意义；主语“Books”为复数，故填sell。 43．will be completed 【详解】句意：据报道，无锡奥林匹克体育中心将于明年完工。句中主语“Wuxi Olympic Sports Center”与动词complete是被动关系，且时间状语“next year”提示用一般将来时，故用一般将来时的被动语态，结构为“will be+过去分词”，complete的过去分词为completed。 44．has repaired 【详解】句意：——我现在可以用电脑查找资料吗？——当然可以。工程师已经修理好它了。随意使用。句中语境强调修理动作已完成且对现在产生影响，提示应用现在完成时，主语The engineer是单数主语，repair“修理”的现在完成时形式为has repaired。 45．to hit 【详解】句意：因此，人们经常看到许多年轻人日夜用功苦读。主动语态中，see的常用结构是see sb. do sth.“看见某人做某事”，用来描述经常性动作/动作全过程，此时作宾语补足语的不定式会省略to。当see变为被动语态时，原本省略的不定式符号to必须还原，结构为sb. be seen to do sth.；本题是被动结构“were often seen”，故填动词不定式to hit。 46．is making 【详解】句意：大家和双胞胎此刻正在制定他们的阅读计划。句中“at the moment”为现在进行时的时间标志词，提示动作此刻正在发生，应使用现在进行时（结构：am/is/are + 动词现在分词）。同时，当主语后接“together with”短语时，谓语动词的单复数由前面的主语决定，本句主语为“Everyone”，因此be动词用“is”；“make”的现在分词形式为“making”。 47．was making 【详解】句意：多么可怕的事故啊！司机可能当时正在打电话。事故已经发生，说明打电话这个动作是事故发生的那一刻正在进行的，所以要用过去进行时；Perhaps表示对过去情况的推测，结合语境，司机打电话是事故发生时的行为，主语“the driver”是第三人称单数，填入was making。 48．shook 【详解】句意：他用力摇晃瓶子，想看看里面有没有水。句中“there was any water inside”使用了一般过去时，提示整个动作发生在过去，应用一般过去时。shake的过去式为不规则变化，故填shook。 49．written 【详解】句意：汉斯·克里斯蒂安·安徒生写的这个故事至今仍很受欢迎。句中“The story”与“write”是被动关系，即“故事被写”，且动作发生在过去，需用过去分词作后置定语，write的过去分词为written，故填written。 50．will be 【详解】句意：你能想象二十年后我们的生活将会是什么样子吗？be意为“是”，是系动词。根据时间状语“in twenty years”可知，动作发生在将来，应用一般将来时，结构为“will+动词原形”。故填will be。 六、阅读表达 （本大题共5小题，每小题2分，共10分） 阅读短文，根据短文内容回答问题。 Ice covers much of the Arctic Ocean (北冰洋). Some pieces of ice are huge, like moving islands. As temperatures have increased, however, some of the ice has begun to disappear. Scientists have discovered huge waves in the Arctic waters. The waves were discovered by accident in May 2010. Scientist Aleksey Marchenko and his students set out on a trip. They wanted to study the icy waters. On May 2, the ship traveled east and stopped next to a large chunk of ice around 50 miles from the small island Hopen. Marchenko prepared to lead his students out onto the ice. “We were ready to go but when I went out, I discovered many cracks (裂缝) around,” he remembers. He decided to move the ship deeper into the ice to keep safe. The farther in they went, he thought, the harder the ice would become. As they pushed forward, however, the ship experienced small waves, and then bigger ones. Soon, the waves broke up the ice around the ship into thousands of smaller pieces. Within an hour, Marchenko and his team saw a wave that was about 13 feet high. The ship’s navigation (航行) system finally recorded the largest waves. They were more than 20 feet in height. The waves were so strong that they forced huge pieces of ice to jump up and down, breaking the ice into smaller pieces within just one hour. Scientists have never imagined that the process could happen so fast. The waves in these areas used to be small. The speed and force of the huge waves there make it impossible to know in advance when they are coming. That could be dangerous for navigators and local communities who are unprepared for huge waves or depend on sea ice to protect them. Wildlife like polar bears and walruses that depend on sea ice to live are also in danger. Some scientists think people will soon see even bigger waves in these icy waters. As waves break up ice, the seas will become more open, and the waves will get even stronger. There are stormy times ahead. 51．When did Marchenko and his students discover huge waves in the Arctic waters? 52．Why has the Arctic ice begun to disappear? 53．How high were the largest waves recorded by the navigation system? 54．Who may be in danger from the huge waves? 55．What can we do to protect the Arctic? 51．In May 2010. 52．Because the temperatures have increased. 53．More than 20 feet in height. 54．Navigators, local communities and wildlife. 55．We should reduce carbon emissions. 【导语】本文主要讲述了科学家在北冰洋意外发现巨浪，分析了巨浪形成的原因、带来的危险以及未来的预测。 【详解】51．文章第二段第一句提到“The waves were discovered by accident in May 2010.”，可知发现巨浪的时间是2010年5月。 52．文章第一段第三句“As temperatures have increased…the ice has begun to disappear.”直接说明了冰消失的原因是因为气温升高。 53．文章第六段指出“They were more than 20 feet in height.”，可知最大波浪的高度超过20英尺。 54．文章第八段提到“That could be dangerous for navigators and local communities…Wildlife…are also in danger.”，可知航海者、社区和野生动物都处于危险中。 55．本题是开放性试题，答案不唯一，但观点需基于文中事实，结合文章内容对“保护北冰洋”给出建议，合理作答即可，注意不超过6个单词。 七、书面表达 (共20分) 56．你校英语社团计划开展“守护长江，绿色未来”主题活动。请根据以下提示，以社团负责人李华的身份写一篇英文倡议书，呼吁全校师生参与环保行动。 现状与挑战：江面塑料污染、过度捕捞破坏生态 (ecosystem) 等问题。 具体倡议：1. 个人行动：减少塑料制品使用，……； 2. 校园行动：两岸植树，……； 3. 科技助力：AI智能监测，……。 要求：1. 词数：不少于90词，开头和结尾已写好，不计入总词数； 2. 倡议书内容必须包括以上要点，可适当发挥； 3. 段落分明，语意通顺，书写规范； 4. 不得出现真实姓名、校名及地名等信息。 Dear teachers and classmates, The Yangtze River, our mother river, is facing ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Remember: every little thing we do brings us closer to a green future. Come and join us today! Dear teachers and classmates, The Yangtze River, our mother river, is facing serious challenges. Plastic pollution is everywhere on the river surface, and overfishing has broken the balance of its ecosystem. It’s time for us to take action to protect it. First, let’s start with personal actions. We should reduce the use of plastic products, such as bringing reusable bags when shopping and refusing disposable tableware. Every small step can cut down plastic waste entering the river. Second, we can organize campus activities. Planting trees along both sides of the Yangtze River can prevent soil erosion and provide a better living environment for aquatic organisms. We can also hold river-cleaning activities on weekends to collect rubbish by the river. Third, we can use technology to help. With AI intelligent monitoring systems, we can track the situation of plastic pollution and illegal fishing in real time. This can help relevant departments take timely measures to stop harmful behaviors. Remember: every little thing we do brings us closer to a green future.

Yang talked excitedly about finding such treasure in January 2022. “We got over 2,450 kilograms of large yellow croakers (大黄鱼) in a net yesterday,” Yang said. “The heaviest one weighed more than two kilograms,” said Lin Haiping, the owner of the fishing boat on which Yang works. “I’ve been fishing for 28 years but never caught so many large yellow croakers of this size before,” Lin added. Fang Yue, an engineer working in Xiangshan, said, “It’s the first time that fishermen have caught so many large yellow croakers in the East China Sea in over 30 years.” There used to be many large yellow croakers in the East China Sea, but the number has dropped for about 45 years because of overfishing. In 1979, Zhejiang started a yearly seasonal ban (禁止) on fishing. Later in 1995, other areas through the whole country followed its example. Fang said that the number of large yellow croakers has become larger because of the sea protection efforts (努力). Fishermen from Xiangshan have made great efforts, too. In 2000, 21 fishermen in Xiangshan set up China’s first volunteer organization to better protect the sea around the world. Today, more than 10,000 people have joined the organization. In 2002, three fishermen from the county wrote to Kofi Annan, calling on people around the world to protect the sea together. Huang Genbao, head of the Xiangshan Fishing Association, said that although harvesting more than 1,000 kg of large yellow croakers doesn’t happen often, he hoped that sea protection would go on and more fishermen would have more fish in the future. 16．How does the writer start the passage? A．By asking a question. B．By giving an example. C．By telling a joke. D．By introducing (介绍) a fisherman. 17．What does the underlined word “it” in the first paragraph refer to (指代)? A．The treasure. B．The harvest. C．The sea. D．The heaviest fish. 18．What is the correct order to show the efforts made in sea protection? ①A yearly seasonal ban on fishing was started in Zhejiang. ②Other areas in our country followed Zhejiang’s example. ③Three fishermen from the county wrote to Kofi Annan, calling on people around the world to protect the sea together. ④To protect the sea around the world, twenty-one fishermen in Xiangshan set up a volunteer organization. A．②①③④ B．①②④③ C．②④③① D．①③②④ 19．What can we learn from the passage? A．Both Yang Tiansheng and Fang Yue are fishermen in Xiangshan County. B．Fishermen like Lin Haiping caught many large yellow croakers in the East China Sea. C．The Zhejiang government set up China’s first volunteer organization to protect the sea. D．Harvesting more than 1,000 kg of large yellow croakers often happens in Zhejiang. 20．Which could be the best title for the passage? A．Harvest of large yellow croakers. B．China’s first volunteer organization. C．Yellow croakers, a local treasure. D．Sea protection works well in Zhejiang. C Rat and Mole are at home all day. Mole is bored. He says, ‘‘I want to visit Badger.” But Rat tells him, “Badger lives in the middle of the Wild Wood. It’s a long way to go in winter.” But Mole still wants to go. When Rat is asleep, he puts on a coat and goes into the Wild Wood. It is cold and the sky is grey, first it is fun. But then it gets dark. Mole sees strange little faces in the wood.

When Rat wakes up at home, he calls, ‘‘Mole, Mole!” but Mole doesn’t answer. And Mole’s coat isn’t there. Rat thinks, “Mole is visiting Badger. Oh, no! Mole is in the Wild Wood!” he puts on his coat and put a gun in his pocket. He goes along the path to the Wild Wood. He sees the strange faces with sharp teeth. But they see Rat’s gun, and go away. Rat calls and calls, “Mole, where are you? It’s me - Rat.” At last, Mole answers. “Rat, I’m here! In the tree! I am very frightened!” he says in a little voice. ‘‘Don’t worry, Mole,” says Rat, “Let’s go home now!” But Mole is very tired. He wants to sleep, so Rat sits and waits. While Mole is sleeping, it begins to snow. The snow is white and it covers all the paths. Later, Mole wakes up. Then the two friends set off through the white woods. Everything is different with the snow and soon Rat and Mole are lost. They walk for hours but they cannot find the way home. They are tired, and cold, and hungry. Suddenly, Rat sees a sign in the snow. The sign says, “Mr Badger”. “It’s Badger’s front door,” says Rat. He is very excited.

Most Chinese hotels often provide guests (客人) with things like disposable (一次性的) toothbrushes, toothpaste, shampoo and slippers. 26 But, if you travel to Beijing, remember to bring your own things. Starting from June, some hotels in Beijing will no longer provide guests with these disposables. 27 Many disposable things are made of plastic (塑料). People throw them away after only using them once. 28 Do you know, one Chinese person makes as much as 400 kg of waste a year! Most of that waste comes from disposable things. In Beijing, people throw away about 19,000 tons of plastic bags and 1,320 tons of plastic lunch bowls every year! Plastic can take between 100 and 400 years to break down. So the less plastic we throw out, the better. 29 Back at home and school, you can also do something to make our world a better place. Try to do these things in your daily life: Use cloth shopping bags. Not plastic ones. After using a plastic bag, wash it out and let it dry. 30 Do not use paper cups. At your school lining room, use your own bowl and chopsticks instead of disposable ones. To protect our environment and our home, it is very necessary and important for us to save natural resources. A．It is a waste of natural resources and is very bad for the environment. B．Many guests like the idea because they don’t have to bring their own. C．Here are some ideas for you to live a green life. D．They want to ask people to use disposable things less. E．Then you can use it over and over again. F．So, wherever you travel, bring your own things and use them again and again.

As waves break up ice, the seas will become more open, and the waves will get even stronger. There are stormy times ahead. 51．When did Marchenko and his students discover huge waves in the Arctic waters? 52．Why has the Arctic ice begun to disappear? 53．How high were the largest waves recorded by the navigation system? 54．Who may be in danger from the huge waves? 55．What can we do to protect the Arctic? 七、书面表达 (共20分) 56．你校英语社团计划开展“守护长江，绿色未来”主题活动。请根据以下提示，以社团负责人李华的身份写一篇英文倡议书，呼吁全校师生参与环保行动。 现状与挑战：江面塑料污染、过度捕捞破坏生态 (ecosystem) 等问题。 具体倡议：1. 个人行动：减少塑料制品使用，……； 2. 校园行动：两岸植树，……； 3. 科技助力：AI智能监测，……。 要求：1. 词数：不少于90词，开头和结尾已写好，不计入总词数； 2. 倡议书内容必须包括以上要点，可适当发挥； 3. 段落分明，语意通顺，书写规范； 4. 不得出现真实姓名、校名及地名等信息。 Dear teachers and classmates, The Yangtze River, our mother river, is facing ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Remember: every little thing we do brings us closer to a green future.

In 1979, Zhejiang started a yearly seasonal ban (禁止) on fishing. Later in 1995, other areas through the whole country followed its example. Fang said that the number of large yellow croakers has become larger because of the sea protection efforts (努力). Fishermen from Xiangshan have made great efforts, too. In 2000, 21 fishermen in Xiangshan set up China’s first volunteer organization to better protect the sea around the world. Today, more than 10,000 people have joined the organization. In 2002, three fishermen from the county wrote to Kofi Annan, calling on people around the world to protect the sea together. Huang Genbao, head of the Xiangshan Fishing Association, said that although harvesting more than 1,000 kg of large yellow croakers doesn’t happen often, he hoped that sea protection would go on and more fishermen would have more fish in the future. 16．How does the writer start the passage?

Most Chinese hotels often provide guests (客人) with things like disposable (一次性的) toothbrushes, toothpaste, shampoo and slippers. 26 But, if you travel to Beijing, remember to bring your own things. Starting from June, some hotels in Beijing will no longer provide guests with these disposables. 27 Many disposable things are made of plastic (塑料). People throw them away after only using them once. 28 Do you know, one Chinese person makes as much as 400 kg of waste a year! Most of that waste comes from disposable things. In Beijing, people throw away about 19,000 tons of plastic bags and 1,320 tons of plastic lunch bowls every year! Plastic can take between 100 and 400 years to break down. So the less plastic we throw out, the better. 29 Back at home and school, you can also do something to make our world a better place. Try to do these things in your daily life: Use cloth shopping bags. Not plastic ones. After using a plastic bag, wash it out and let it dry. 30 Do not use paper cups. At your school lining room, use your own bowl and chopsticks instead of disposable ones. To protect our environment and our home, it is very necessary and important for us to save natural resources. A．It is a waste of natural resources and is very bad for the environment. B．Many guests like the idea because they don’t have to bring their own. C．Here are some ideas for you to live a green life.

Some pieces of ice are huge, like moving islands. As temperatures have increased, however, some of the ice has begun to disappear. Scientists have discovered huge waves in the Arctic waters. The waves were discovered by accident in May 2010. Scientist Aleksey Marchenko and his students set out on a trip. They wanted to study the icy waters. On May 2, the ship traveled east and stopped next to a large chunk of ice around 50 miles from the small island Hopen. Marchenko prepared to lead his students out onto the ice. “We were ready to go but when I went out, I discovered many cracks (裂缝) around,” he remembers. He decided to move the ship deeper into the ice to keep safe. The farther in they went, he thought, the harder the ice would become. As they pushed forward, however, the ship experienced small waves, and then bigger ones. Soon, the waves broke up the ice around the ship into thousands of smaller pieces. Within an hour, Marchenko and his team saw a wave that was about 13 feet high. The ship’s navigation (航行) system finally recorded the largest waves. They were more than 20 feet in height. The waves were so strong that they forced huge pieces of ice to jump up and down, breaking the ice into smaller pieces within just one hour. Scientists have never imagined that the process could happen so fast. The waves in these areas used to be small. The speed and force of the huge waves there make it impossible to know in advance when they are coming. That could be dangerous for navigators and local communities who are unprepared for huge waves or depend on sea ice to protect them. Wildlife like polar bears and walruses that depend on sea ice to live are also in danger. Some scientists think people will soon see even bigger waves in these icy waters. As waves break up ice, the seas will become more open, and the waves will get even stronger. There are stormy times ahead. 51．When did Marchenko and his students discover huge waves in the Arctic waters? 52．Why has the Arctic ice begun to disappear? 53．How high were the largest waves recorded by the navigation system? 54．Who may be in danger from the huge waves? 55．What can we do to protect the Arctic? 七、书面表达 (共20分) 56．你校英语社团计划开展“守护长江，绿色未来”主题活动。请根据以下提示，以社团负责人李华的身份写一篇英文倡议书，呼吁全校师生参与环保行动。 现状与挑战：江面塑料污染、过度捕捞破坏生态 (ecosystem) 等问题。 具体倡议：1. 个人行动：减少塑料制品使用，……； 2. 校园行动：两岸植树，……； 3. 科技助力：AI智能监测，……。 要求：1. 词数：不少于90词，开头和结尾已写好，不计入总词数； 2. 倡议书内容必须包括以上要点，可适当发挥； 3. 段落分明，语意通顺，书写规范； 4. 不得出现真实姓名、校名及地名等信息。 Dear teachers and classmates, The Yangtze River, our mother river, is facing ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Remember: every little thing we do brings us closer to a green future.
