We turned an unused corner of the playground into a small garden, and every class took turns to take care of it. First, we learned about different plants from our science teacher. We planted sunflowers, tomatoes and mint. Every morning, we watered them, pulled weeds and talked to them like old friends. At first, some plants didn’t grow well, but we tried different ways—like adding more soil or moving them to sunnier places. Now the Green Classroom is amazing! The sunflowers are taller than me, the tomatoes are red and sweet, and the mint smells fresh when we touch it. We even use the mint to make tea for our teachers. This garden didn’t just grow plants—it grew our love for nature. We learned that nature needs our care, and when we care for it, it gives us back so much joy. 去年，我们学校启动了一个特别的项目：绿色教室。我们把操场的一个闲置角落改造成了小花园，每个班级轮流负责打理。 首先，我们从科学老师那里学习了不同植物的知识，种下了向日葵、番茄和薄荷。每天早上，我们给它们浇水、除草，像老朋友一样和它们说话。起初，有些植物长势不好，但我们尝试了不同的方法——比如加更多的土，或者把它们移到阳光更充足的地方。 现在，绿色教室变得生机勃勃！向日葵长得比我还高，番茄又红又甜，薄荷被触碰时散发出清新的香气。我们甚至用薄荷给老师们泡茶。这个花园不仅种出了植物，更种下了我们对自然的热爱。我们明白了，自然需要我们的呵护，而当我们用心对待它时，它会回馈给我们无尽的快乐。 【长难句分析】 1."We turned an unused corner of the playground into a small garden, and every class took turns to take care of it." 翻译：我们把操场的一个闲置角落改造成了小花园，每个班级轮流负责打理。 重点：turn...into...（把……变成……）是单元核心短语，贴合“改造自然空间”的主题；take turns to do sth.（轮流做某事）清晰描述班级协作模式；and连接两个并列动作，结构清晰。 2."At first, some plants didn’t grow well, but we tried different ways—like adding more soil or moving them to sunnier places." 翻译：起初，有些植物长势不好，但我们尝试了不同的方法——比如加更多的土，或者把它们移到阳光更充足的地方。 重点：but表转折，体现“遇到问题→解决问题”的实践过程；破折号后举例说明具体方法，贴合园艺实践场景；sunnier places（更充足的阳光处）用形容词比较级，符合七年级语法要求。 3."This garden didn’t just grow plants—it grew our love for nature.

Recently, our local environmental group found something amazing: a small number of northern leopard frogs living in the river. These frogs are very special. They are very sensitive to pollution, so if they are alive and healthy, it means the river water is clean. Years ago, the river was full of trash and the water was dark. No one saw frogs there for a long time. But now, thanks to a city-wide cleanup project and new laws to stop pollution, the river is getting better. Seeing the frogs come back is a sign of hope. It tells us that nature is strong, and if we take action to protect it, even small changes can make a big difference. The frogs are not just cute animals—they are our river’s health report. 很多人觉得自然离我们很遥远，但它就在我们的城市里——甚至就在穿过小镇的那条河里。最近，我们当地的环保组织发现了一件令人惊喜的事：河里生活着一小群北方豹蛙。 这些青蛙非常特别，它们对污染极其敏感，所以如果它们能健康地活着，就说明河水是干净的。多年前，这条河满是垃圾，河水浑浊发黑，很长时间都没人在这里见过青蛙了。但现在，多亏了全市范围的清理项目和阻止污染的新法规，河流正在慢慢变好。 看到青蛙回来，是希望的象征。它告诉我们，自然是有韧性的，只要我们采取行动保护它，哪怕是微小的改变也能带来巨大的不同。这些青蛙不只是可爱的动物——它们就是我们河流的“健康报告”。 【长难句分析】 1"Many people think nature is far away, but it’s right in our city—even in the river that runs through our town." 翻译：很多人觉得自然离我们很遥远，但它就在我们的城市里——甚至就在穿过小镇的那条河里。 重点：but表转折，打破“自然在远方”的固有认知；that引导定语从句修饰river，巩固单元语法知识点；破折号后补充说明，让“自然就在身边”的观点更具体。 2."These frogs are very special. They are very sensitive to pollution, so if they are alive and healthy, it means the river water is clean." 翻译：这些青蛙非常特别，它们对污染极其敏感，所以如果它们能健康地活着，就说明河水是干净的。 重点：be sensitive to（对……敏感）是环保主题核心短语；so表因果，清晰解释青蛙作为“环境指示器”的作用；if引导条件状语从句，符合七年级语法进阶要求。 3."It tells us that nature is strong, and if we take action to protect it, even small changes can make a big difference." 翻译：它告诉我们，自然是有韧性的，只要我们采取行动保护它，哪怕是微小的改变也能带来巨大的不同。 重点：that引导宾语从句，传递“自然有韧性”的核心观点；if引导条件状语从句，强调“行动带来改变”；make a big difference（带来巨大不同）是单元核心表达，贴合环保主题。 【重难词汇梳理】 1.frog /frɒɡ/ (n.) 青蛙 2.northern leopard frog 北方豹蛙 3.sensitive /ˈsensətɪv/ (adj.) 敏感的 4.pollution /pəˈluːʃn/ (n.) 污染 5.trash /træʃ/ (n.) 垃圾 6.cleanup /ˈkliːnʌp/ (n.) 清理；净化 7.law /lɔː/ (n.) 法律；法规 8.sign /saɪn/ (n.) 标志；迹象 9.hope /həʊp/ (n.) 希望 10.make a big difference 产生巨大影响；带来不同 实战演练 Passage1 （25-26七年级下·全国·课后作业）Plants are very important living things.

The weather may be very cold. Food can be hard to find under the snow. How do animals live in this time? Let’s have a look. In fall when the weather gets cool, some animals go away from cold places and move to warm places. Some birds fly to south together because the weather there is warm and food there is easy to find. When warm days come, they will be back. Some animals make changes to live in winter, like snowshoe rabbits in America. In summer, the rabbits’ fur (毛) is brown. But they grow new white fur in winter. The new fur keeps them safe (安全的) in snow. In fall, they eat to get fat (脂肪), because the fat can also help them keep warm in winter. Other animals sleep all winter and they don’t eat at all. Before winter, these animals eat a lot to grow fat. When winter comes, they go to sleep. Black bears in cold places make beds to sleep in. Some of them can sleep for seven months. 1．Which animals will probably move to south in winter? A．Rabbits. B．Snakes. C．Birds. D．Bears. 2．What color is the fur of snowshoe rabbits in winter? A．Brown. B．White. C．Yellow. D．Green. 3．What is the right structure (结构) of the text? (① =Paragraph 1) A． B． C． D． 4．What can be the best title for the text? A．How Animals Live in Winter B．Where Animals Stay in Winter C．Why Animals Sleep in Winter D．What Animals Eat in Winter 【答案】1．C 2．B 3．A 4．A 【导语】本文主要讲述了动物在冬天的不同生存方式。 1．细节理解题。根据“Some birds fly to south together because the weather there is warm and food there is easy to find.”可知，一些鸟类会在冬天飞往南方，故选C。 2．细节理解题。根据“But they grow new white fur in winter.”可知，雪兔在冬天的皮毛是白色的，故选B。 3．篇章结构题。根据全文可知，第一段总起提出“动物如何在冬天生存”的问题；第二段、第三段、第四段分别介绍了迁徙、自身变化、冬眠这三种不同的生存方式，是“总-分”结构，对应选项A的结构，故选A。 4．最佳标题题。根据“How do animals live in this time? Let’s have a look.”及全文分别介绍动物在冬天的三种生存方式可知，本文的最佳标题是“动物如何在冬天生存”，故选A。 Passage3 （25-26七年级上·浙江金华·期末）Think about walking in a quiet place in Australia. Suddenly, you hear a strange “Oom” sound. This sound may come from a bird in great danger—the plains-wanderer (领鹑)! Scientists in Australia use Artificial Intelligence (AI) to find and protect these birds. These birds are very tiny, only about 15 cm tall. They are also very careful about their home. They live in places with grass, but the grass can’t be too much or too little. For this reason, scientists call them the “Goldilocks of animals” because they need a place that is just right. Long ago, many of these birds lived in the east of Australia. Now, there are only 250 to 1,000. They are not good at flying. When they are afraid, they don’t fly away, but they hide or run. “There is no bird like it in the world,” says a scientist. To protect these birds, scientists first need to know where they are. They know the mother birds make the “Oom” sound. They try to catch these sounds. However, it is difficult for humans to recognize all of them, so the team uses AI to help. The AI finds the bird’s sound in two places. One scientist says it feels like “finding gold”. It is the first time in over 30 years that people find these birds in the west of Melbourne! 1．How do the scientists find the birds? A．By walking in a quiet place. B．By using Artificial Intelligence. C．By looking for them everywhere. D．By taking many photos of their home. 2．What does the word “tiny” probably mean in Paragraph 2? A．Small. B．Quiet. C．Strong. D．Fast. 3．What do these birds do when they feel afraid? A．They make a loud sound. B．They try to fly away quickly. C．They hide somewhere or run away. D．They ask mother birds for help. 4．What is the main purpose (意图) of this passage? A．To introduce the home of the plains-wanderer. B．To introduce the peaceful life of birds in Australia. C．To tell us why some birds are not good at flying. D．To tell us how scientists protect the birds with AI. 【答案】1．B 2．A 3．C 4．D 【导语】本文主要介绍了澳大利亚科学家如何使用人工智能（AI）来寻找和保护一种名为“领鹑”的濒危鸟类。 1．细节理解题。根据文章第一段“Scientists in Australia use Artificial Intelligence (AI) to find and protect these birds.”可知，科学家是通过人工智能（AI）来寻找这些鸟的。故选B。 2．词句猜测题。根据文章第二段“only about 15 cm tall”可知，这种鸟只有大约15厘米高，非常矮小。因此，“tiny”的意思应为“小的”。故选A。 3．细节理解题。根据文章第三段“When they are afraid, they don’t fly away, but they hide or run.”可知，当这些鸟感到害怕时，它们会躲藏或逃跑。故选C。 4．主旨大意题。通读全文，文章不仅介绍了领鹑这种鸟的基本信息，更重要的是讲述了科学家如何利用AI技术来定位和保护它们。因此，文章的主要意图是告诉我们科学家如何用AI来保护这些鸟。故选D。 Passage4 （24-25七年级下·全国·课后作业）Do you know anything about the balance of nature? Here is an example. Not many years ago, some farmers were worried because hawks (鹰) took many of their chickens, so the farmers killed many hawks. They didn’t need to worry about their chickens. But then they had new worries. Mice ate the farmers’ food. How did this happen? Hawks ate not only chickens but also mice. They ate more mice than chickens. But the farmers did not know this. When they killed many hawks, they changed the balance of nature. Changing the balance is bad for nature. Sometimes when people move into a new place, they often cut down many plants. Some of these plants are food for animals. If the animals cannot find food to eat, they will die. Here is another example. In a place of the US, the giraffes ate a kind of rose, and the lions there ate the giraffes. But people killed many lions to protect the giraffes. Soon many giraffes ate up all the roses. Then the giraffes began to eat leaves of young trees. These trees were important to people. So people thought of many ways to protect trees. Now the giraffes had nothing to eat, and many of them died. This was another lesson from nature. Please always keep this in mind: It’s important for us to keep the balance of nature. 1．How does the writer start the passage? A．By giving a fact. B．By asking a question. C．By giving an opinion. D．By telling a life story. 2．What does the underlined word “they” in Paragraph 2 refer to? A．The hawks. B．The mice. C．The chickens. D．The farmers. 3．Which one shows the right relation (关系) of giraffes, lions, roses and trees? A． B． C． D． 4．What is the main idea of the passage? A．Farmers can’t change the balance. B．Animals are bad for grains and plants. C．People can always learn from the nature. D．We should not change the balance of nature. 5．In which kind of book can you find this passage? A．Subjects and clubs. B．Art and music. C．Animals and people. D．Languages and countries. 【答案】1．B 2．D 3．A 4．D 5．C 【导语】本文主要通过几个例子阐述了保持自然平衡的重要性。 1．细节理解题。根据“Do you know anything about the balance of nature? Here is an example.”可知，作者通过提问的方式开启文章。故选B。 2．细节理解题。根据“But then they had new worries. Mice ate the farmers’ food. How did this happen? Hawks ate not only chickens but also mice. They ate more mice than chickens. But the farmers did not know this. When they killed many hawks, they changed the balance of nature.”可知，第二段中“they”指代的是农民，因为农民杀了许多鹰，改变了自然的平衡，导致老鼠吃农民的食物。故选D。 3．推理判断题。根据“In a place of the US, the giraffes ate a kind of rose, and the lions there ate the giraffes.”以及“Then the giraffes began to eat leaves of young trees.”可知，狮子吃长颈鹿，长颈鹿吃玫瑰和树上的叶子，所以正确的顺序是：狮子→长颈鹿→玫瑰和树，选项A结构图符合。故选A。 4．主旨大意题。通读全文可知，本文主要讲述了人们不应该改变自然的平衡，改变自然的平衡对自然有害，并通过几个例子来说明这一点。故选D。 5．推理判断题。通读全文可知，本文围绕人与动物以及自然平衡展开，最有可能在“动物与人”板块。故选C。 Passage5 （25-26七年级下·全国·单元测试）阅读下面短文，简略回答问题。 Imagine your school has a garden. You can plant vegetables there. Sounds cool, doesn’t it? The students at No. 1 Middle School get to do this now. They plant vegetables in their school garden. The science teacher Ms. Wang has a vegetable garden in the school. The students plant vegetable seeds in the garden in spring. They water and watch the vegetables grow. They enjoy the vegetables in autumn. What great fun it is! The school garden is a good place for them to learn the ways to grow plants. Some Grade 7 students plant about 5 vegetables in the garden. They want to know how things like soil and water affect (影响) the vegetables’ growth. Li Ke is one of the Grade Seven students. She likes working in the school garden. “It is good for us to eat vegetables in different colors. I am happy to pick all kinds of colorful vegetables here,” she says. Tips: Why do vegetables have different colors? Actually, colors don’t just make vegetables look good. Vegetables in different colors give different vitamins (维生素) and minerals (矿物质). Every day, if you eat vegetables of different colors, you will become very healthy! 1．At No. 1 Middle School, what do the students do in the school garden? 2．When do they plant vegetable seeds in the garden? 3．How many vegetables do the students in Grade 7 plant in the garden? 4．Why is it healthy to eat vegetables in different colors? 5．(开放题) What kind of vegetables do you like to eat? Why? 【答案】1．They plant vegetables. 2．In spring. 3．About 5 vegetables. 4．Because vegetables in different colors give different vitamins and minerals. 5．I like to eat carrots. Because they are orange and rich in vitamin A, which is good for my eyes. (根据自身情况作答) 【导语】本文主要讲述了第一中学的学生在学校菜园种植蔬菜的活动，以及不同颜色蔬菜的健康益处。 1．根据“They plant vegetables in their school garden.”和“The students plant vegetable seeds in the garden in spring. They water and watch the vegetables grow. They enjoy the vegetables in autumn.”可知，学生们在学校菜园里种植蔬菜，春天播种、浇水照看蔬菜生长，秋天收获蔬菜，还能学习种植植物的方法，故填They plant vegetables. 2．根据“The students plant vegetable seeds in the garden in spring.”可知，他们在春天播种蔬菜种子，故填In spring. 3．根据“Some Grade 7 students plant about 5 vegetables in the garden.”可知，七年级的学生在菜园里种植大约5种蔬菜，故填About 5 vegetables. 4．根据“Vegetables in different colors give different vitamins and minerals. Every day, if you eat vegetables of different colors, you will become very healthy!”可知，不同颜色的蔬菜能提供不同的维生素和矿物质，所以吃不同颜色的蔬菜有益健康，故填Because vegetables in different colors give different vitamins and minerals. 5．本题为开放性问题，答案不唯一，结合自身喜好和合理理由即可。故填I like to eat carrots. Because they are orange and rich in vitamin A, which is good for my eyes. $Unit 8 I love nature! 话题阅读精练 模块 语篇 题型 体裁 词数 内容简介 时文阅读 Passage1 阅读理解 记叙文 168词 学生照料校园绿色教室，在实践中爱上自然 Passage2 阅读理解 说明文 162词 北方豹蛙重现河流，印证环境改善，彰显环保价值 实战演练 Passage1 完形填空 说明文 185词 介绍植物的重要性及开花与不开花植物的繁殖方式 Passage2 阅读理解（选择题） 说明文 156词 介绍动物冬季的三种生存方式：迁徙、变化、冬眠 Passage3 阅读理解（选择题） 说明文 132词 澳科学家用AI寻找并保护濒危鸟类领鹑 Passage4 阅读理解（选择题） 说明文 198词 阐述破坏自然平衡的危害，强调保持平衡的重要性 Passage5 阅读理解（回答问题） 记叙文 198词 学生在校园菜园种菜，介绍不同颜色蔬菜的健康益处 时文阅读 Passage1 The "Green Classroom" That Grew Our Love for Nature（让我们爱上自然的“绿色教室”） Last year, our school started a special project: a Green Classroom.

They get their food by eating plants and 4 animals. So animals and man need plants in order to 5 . This is why we find that there are so many plants around us. If you look carefully 6 the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are 7 by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. 8 non-flowering plants do not grow flowers. They can not make seeds.

The weather may be very cold. Food can be hard to find under the snow. How do animals live in this time? Let’s have a look. In fall when the weather gets cool, some animals go away from cold places and move to warm places. Some birds fly to south together because the weather there is warm and food there is easy to find. When warm days come, they will be back. Some animals make changes to live in winter, like snowshoe rabbits in America. In summer, the rabbits’ fur (毛) is brown. But they grow new white fur in winter. The new fur keeps them safe (安全的) in snow. In fall, they eat to get fat (脂肪), because the fat can also help them keep warm in winter. Other animals sleep all winter and they don’t eat at all. Before winter, these animals eat a lot to grow fat. When winter comes, they go to sleep. Black bears in cold places make beds to sleep in. Some of them can sleep for seven months. 1．Which animals will probably move to south in winter? A．Rabbits. B．Snakes. C．Birds. D．Bears. 2．What color is the fur of snowshoe rabbits in winter? A．Brown. B．White. C．Yellow. D．Green. 3．What is the right structure (结构) of the text? (① =Paragraph 1) A． B． C． D． 4．What can be the best title for the text?

Suddenly, you hear a strange “Oom” sound. This sound may come from a bird in great danger—the plains-wanderer (领鹑)! Scientists in Australia use Artificial Intelligence (AI) to find and protect these birds. These birds are very tiny, only about 15 cm tall. They are also very careful about their home. They live in places with grass, but the grass can’t be too much or too little. For this reason, scientists call them the “Goldilocks of animals” because they need a place that is just right. Long ago, many of these birds lived in the east of Australia. Now, there are only 250 to 1,000. They are not good at flying. When they are afraid, they don’t fly away, but they hide or run. “There is no bird like it in the world,” says a scientist. To protect these birds, scientists first need to know where they are. They know the mother birds make the “Oom” sound. They try to catch these sounds. However, it is difficult for humans to recognize all of them, so the team uses AI to help. The AI finds the bird’s sound in two places. One scientist says it feels like “finding gold”. It is the first time in over 30 years that people find these birds in the west of Melbourne! 1．How do the scientists find the birds? A．By walking in a quiet place. B．By using Artificial Intelligence. C．By looking for them everywhere. D．By taking many photos of their home. 2．What does the word “tiny” probably mean in Paragraph 2? A．Small. B．Quiet. C．Strong. D．Fast. 3．What do these birds do when they feel afraid? A．They make a loud sound. B．They try to fly away quickly. C．They hide somewhere or run away. D．They ask mother birds for help. 4．What is the main purpose (意图) of this passage? A．To introduce the home of the plains-wanderer. B．To introduce the peaceful life of birds in Australia. C．To tell us why some birds are not good at flying. D．To tell us how scientists protect the birds with AI. Passage4 （24-25七年级下·全国·课后作业）Do you know anything about the balance of nature? Here is an example. Not many years ago, some farmers were worried because hawks (鹰) took many of their chickens, so the farmers killed many hawks. They didn’t need to worry about their chickens. But then they had new worries. Mice ate the farmers’ food. How did this happen? Hawks ate not only chickens but also mice. They ate more mice than chickens. But the farmers did not know this. When they killed many hawks, they changed the balance of nature. Changing the balance is bad for nature. Sometimes when people move into a new place, they often cut down many plants. Some of these plants are food for animals. If the animals cannot find food to eat, they will die. Here is another example. In a place of the US, the giraffes ate a kind of rose, and the lions there ate the giraffes. But people killed many lions to protect the giraffes. Soon many giraffes ate up all the roses. Then the giraffes began to eat leaves of young trees. These trees were important to people. So people thought of many ways to protect trees. Now the giraffes had nothing to eat, and many of them died. This was another lesson from nature. Please always keep this in mind: It’s important for us to keep the balance of nature. 1．How does the writer start the passage? A．By giving a fact. B．By asking a question. C．By giving an opinion. D．By telling a life story. 2．What does the underlined word “they” in Paragraph 2 refer to? A．The hawks. B．The mice. C．The chickens. D．The farmers. 3．Which one shows the right relation (关系) of giraffes, lions, roses and trees? A． B． C． D． 4．What is the main idea of the passage? A．Farmers can’t change the balance. B．Animals are bad for grains and plants. C．People can always learn from the nature. D．We should not change the balance of nature. 5．In which kind of book can you find this passage? A．Subjects and clubs. B．Art and music. C．Animals and people. D．Languages and countries. Passage5 （25-26七年级下·全国·单元测试）阅读下面短文，简略回答问题。 Imagine your school has a garden. You can plant vegetables there. Sounds cool, doesn’t it? The students at No. 1 Middle School get to do this now. They plant vegetables in their school garden. The science teacher Ms. Wang has a vegetable garden in the school. The students plant vegetable seeds in the garden in spring. They water and watch the vegetables grow. They enjoy the vegetables in autumn. What great fun it is! The school garden is a good place for them to learn the ways to grow plants. Some Grade 7 students plant about 5 vegetables in the garden. They want to know how things like soil and water affect (影响) the vegetables’ growth. Li Ke is one of the Grade Seven students. She likes working in the school garden. “It is good for us to eat vegetables in different colors. I am happy to pick all kinds of colorful vegetables here,” she says. Tips: Why do vegetables have different colors? Actually, colors don’t just make vegetables look good. Vegetables in different colors give different vitamins (维生素) and minerals (矿物质). Every day, if you eat vegetables of different colors, you will become very healthy! 1．At No. 1 Middle School, what do the students do in the school garden? 2．When do they plant vegetable seeds in the garden? 3．How many vegetables do the students in Grade 7 plant in the garden? 4．Why is it healthy to eat vegetables in different colors? 5．(开放题) What kind of vegetables do you like to eat?
