In countries such as Nigeria and India, people have used it for hundreds of years because almost every part of this amazing tree is valuable. What makes the moringa tree so wonderful? First, it is packed with nutrients. Its leaves are rich in vitamins and minerals (矿物质) —— people cook them as vegetables, dry them for tea, or even make powder for soups. The flowers add flavour to dishes, while the roots (根) can be turned into medicine to treat stomachaches and other illnesses. Even the seeds produce edible oil! Another key benefit is its role in fighting hunger. In dry African areas, families plant moringa trees near homes because they grow incredibly fast——reaching 3 metres in just 6 months! They provide daily fresh leaves for meals and need very little water, making them perfect for drought-resistant farming. Sadly, many moringa trees are disappearing as people cut them down for firewood or building materials. To save these “life trees”, scientists from organisations like the FAO are teaching communities how to grow moringa sustainably while protecting existing trees. They hope this natural gift will continue to help people worldwide. 1．Where does the moringa tree mainly grow? 2．Why is the moringa tree called the “tree of life”? 3．What can people use the roots of the moringa tree for? 4．Why is the moringa tree good for dry areas? 5．What are scientists doing to protect moringa trees? Passage 02 阅读下面短文，回答问题。 Felix, a German boy, gave a class presentation on climate change and deforestation (滥伐森林) when he was only nine. He challenged people to plant one million trees. Nobody expected much from his school project, but Felix’s efforts led to the planting of over 14 billion trees worldwide before he turned 20. Just one year after his class presentation, he and his classmates began the “Plant-for-the-Planet” project by planting a tree outside their school. Other schools soon joined in. When he was 13, he spoke at the United Nations. He said, “We can’t rely on adults alone to save the future. We must take action ourselves.” Today, Felix has just passed his twentieth birthday. “Plant-for-the-Planet” is a large organization with over 70,000 members, teaching about climate change and encouraging tree planting. The goal has grown from one million trees to one trillion on the Earth. Felix keeps speaking to world leaders about climate change. He says, “We can’t wait for a new generation to take charge. We must push current (现任的) world leaders in the right direction, as time is running out.” 6．Felix never gave a class presentation on climate change and deforestation when he was only nine, did he?   7．How many trees did Felix’s efforts lead to planting worldwide before he turned 20? 8．How did he and his classmates begin the “Plant-for-the-Planet” project? 9．What are the main activities of “Plant-for-the-Planet” as a large organization? 10．Felix and “Plant-for-the-Planet” have made a big difference in the world. Can you find some facts from the passage? Please list at least two facts. 11．What do you think of Felix? Why? Passage 03 阅读下面短文，回答问题。 The Huge Baobab (猴面包树) One of the most amazing trees in the world is known as the baobab. This kind of tree mainly grows in South Africa and Australia. Sometimes, it is hard to tell what the name of a tree is because they look the same as each other. But this is not a problem with the baobab. Its appearance is quite different, so people can’t mistake it for another tree. The baobab is very wide at the base, so people often take shelter under it. One Australian baobab was so large that people were able to turn part of the tree into a small room. Travelers were accommodated inside the tree room as a resting place when they went on a trip to the city. The tree itself was so strong and wide that it could hold a large group of people. The oldest tree in the world is over 1, 835 years old now. People also call it the “giving tree”. The delicious tree’s fruit is eaten in many African countries. The fruits have also been found to be very healthy. People make porridge and drinks from the fruit. Since the tree grows in dry environments, it has to store water. The tree takes in water when it is wet. During dry seasons, the baobab tree can use the stored water, and people can also get clean drinking water from it. Some baobabs can store thousands of gallons of water, which helps people survive in dry areas. Of course, the baobabs also provide the people of sunny South Africa with shelters during hot African days. Sadly, in recent years, the baobab trees are dying because of climate change. Scientists are trying hard to take action to protect them. 12．Where does the baobab tree mainly grow? They mainly grow . 13．Can people mistake the baobab for another tree? 14．How old is the oldest tree in the world? The oldest tree in the world . 15．When can the baobab tree use the stored water? The baobab tree can use the stored water . 16．Why do people also call the baobab tree the “giving tree”? 17．What can local people do to protect baobab trees? Please think of at least two ways. Passage 04 阅读下面短文，回答问题。 For a long time, scientists did not know that trees could sense things. Now they are discovering many surprising facts. Trees can sense directions with their roots. They can feel “up” and “down” underground. There is no light in the soil, but roots always grow in the right way. Trees can feel different temperatures. They know when to drop their leaves in autumn and grow new leaves in spring. When animals eat a tree’s leaves, the tree can protect itself. It can make its leaves taste bad so that fewer animals will eat them. Tree roots can also sense sounds. They like the sound of running water very much. When it is dry, roots will grow towards the water. Trees can sense light and colours. They know where the sun is, so their branches grow towards it. Scientists are still learning more about the amazing senses of trees. 18．Why did Lu Yu write Cha Jing? 19．What did scientists not know about trees in the past? 20．How do tree roots know which way to grow underground? 21．How do trees know when to drop their leaves and grow new ones? 22．What will a tree do if a deer starts eating its leaves? Passage 05 阅读下面短文，回答问题。 Trees are one of the oldest “citizens” of our Earth. They keep our air clean, reduce noise pollution, improve water quality and provide food and building materials. Just like us, trees change a lot as they grow. At 1 to 3 years old, young trees learn how to protect themselves. For example, many trees grow thorns (刺) to warn animals not to go near. Most young trees have large, deep green leaves so that they can catch enough sunlight and change it into their food and energy. When trees are 4 years old, they begin to grow very rapidly and become strong enough to face challenges later in life. At the age of 15, trees become young adults. They grow more slowly and begin to produce flowers and fruit. It is not until the tree is 20 to 25 years old that it becomes a real adult. The tree reaches its largest size. Not only does the adult tree give us shade, oxygen and natural beauty, but it is also a great place for a tree house or a place for us to nap, read a book, listen to music or sip tea. If the adult tree receives proper care, it will continue to live healthily for many years. Gradually, trees begin to grow older and older and even die. At this time, they still have their important place in nature. When a tree becomes hollow or part of it becomes dead, it provides a home to small animals and is a source of food for many other animals. In many ways, the life of a tree is similar to our own life experience. When looking at the life of a tree, we learn that each period of life brings its own form of joy and challenge. Enjoy every minute of the life of the trees and take care of the trees. 23．Are trees one of the oldest “citizens” of our Earth? 24．How do young trees protect themselves? 25．Do all young trees have large, deep green leaves? 26．When do trees grow more slowly and begin to produce flowers and fruit? 27．What can a tree be used as when it becomes hollow? 28．What does the writer suggest we do with the trees? 句子翻译 1.亚马逊雨林覆盖了大约670万平方公里。 _____________________________________________________________________ 2.森林覆盖了地球陆地面积的大约31%。 _____________________________________________________________________ 3.九寨沟有超过100个湖泊。 _____________________________________________________________________ 4.这棵树的高度达到了116.07米。 _____________________________________________________________________ 5.超过四分之三的人住在森林附近。 _____________________________________________________________________ 6. 科学家们认为在地球上生物已经存在了数百万年。（millions of） _____________________________________________________________________ 7. 令我们惊讶的是，上个月我们厂的产量仅增加了百分之二。（production, increase by） _____________________________________________________________________ 8. 泰国是我们将去参观的第二个在亚洲的国家。（be going to） _____________________________________________________________________ 9. 火星上的重力大约是地球上的八分之三。（gravity） _____________________________________________________________________ 10· 请把这张重要的通知贴在告示牌上，以便全体学生都能看到。（so that） _____________________________________________________________________ 话题写作 1．请以Protect Trees为题，写一篇英语短文，需满足以下要求： 1）. 词数：60词左右，书写工整，语句通顺； 2）. 内容要点：①阐述树木的重要作用（净化空气、提供氧气、美化环境、为动物提供家园）；②写出保护树木的具体做法（不砍伐树木、多植树、节约用纸）；③发出保护树木的呼吁； 3）. 语法正确，贴合本单元所学词汇、句型，不得出现真实姓名和班级。 _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 2．假设你是一名广州的七年级学生李华，你的学校将举行环保周活动，请根据以下要点提示，完成一篇保护树木的演讲稿，号召大家一起行动起来，保护树木。 树木对人类的重要性 1. 树木能帮助清洁空气，是动物的家园。 2. 树木为人们提供水果、木材等，让人类生活更方便。 3. 树能吸收温室气体，产生氧气。 如何保护树木？ 1. 停止砍伐树木。 2. 使用纸的两面，节约用纸等。 3. （自己补充至少一点） 号召大家保护树木 …… 要求： 1. 必须包含以上提示内容，可适当发挥； 2. 条理清楚、行文连贯、标点正确、书面整洁； 3. 不得出现真实姓名和校名； 4. 60词左右。开头已给出，不计入总词数。参考词汇：disposable chopsticks一次性筷子 Dear students, I am Li Hua.

They can feel “up” and “down” underground.”可知，树根通过感受地下的“上”和“下”来知道在地下的生长方向。 21．根据“Trees can feel different temperatures. They know when to drop their leaves in autumn and grow new leaves in spring.”可知，树木通过感受不同的温度来知道何时落叶和长出新叶。 22．根据“When animals eat a tree’s leaves, the tree can protect itself. It can make its leaves taste bad so that fewer animals will eat them.”可知，当动物开始吃树叶时，树会让树叶变得难吃，这样就会有更少的动物吃它们。 Passage 05 阅读下面短文，回答问题。 Trees are one of the oldest “citizens” of our Earth. They keep our air clean, reduce noise pollution, improve water quality and provide food and building materials. Just like us, trees change a lot as they grow. At 1 to 3 years old, young trees learn how to protect themselves. For example, many trees grow thorns (刺) to warn animals not to go near. Most young trees have large, deep green leaves so that they can catch enough sunlight and change it into their food and energy. When trees are 4 years old, they begin to grow very rapidly and become strong enough to face challenges later in life. At the age of 15, trees become young adults. They grow more slowly and begin to produce flowers and fruit. It is not until the tree is 20 to 25 years old that it becomes a real adult. The tree reaches its largest size. Not only does the adult tree give us shade, oxygen and natural beauty, but it is also a great place for a tree house or a place for us to nap, read a book, listen to music or sip tea. If the adult tree receives proper care, it will continue to live healthily for many years. Gradually, trees begin to grow older and older and even die. At this time, they still have their important place in nature. When a tree becomes hollow or part of it becomes dead, it provides a home to small animals and is a source of food for many other animals.

They grow more slowly and begin to produce flowers and fruit.”，文中通过具体年龄数字交代了树木进入生长缓慢期并开始开花结果的阶段。 27．第三段描述了树木衰老后的作用：“When a tree becomes hollow…it provides a home to small animals and is a source of food for many other animals.”，这直接说明当树木变空心时，可以作为小动物的家园和食物来源。 28．文章最后一句提出了作者的建议：“Enjoy every minute of the life of the trees and take care of the trees.”，这直接表达了作者希望人们能够享受树木生命的每一分钟并悉心照料它们。 句子翻译 1.亚马逊雨林覆盖了大约670万平方公里。 _____________________________________________________________________ 翻译：The Amazon rainforest covers an area of about 6.7 million square kilometres. 解析： “覆盖面积” 常用表达 cover an area of... 数字表达：670万 对应英文 6.7 million 2.森林覆盖了地球陆地面积的大约31%。 _____________________________________________________________________ 翻译：Forests cover about 31% of the Earth's land area. 解析： 百分比表达：31% 直接写作 31%，读作 thirty-one percent the Earth's land area 表示 “地球陆地面积”，用名词所有格更简洁。 3.九寨沟有超过100个湖泊。 _____________________________________________________________________ 翻译：There are more than 100 lakes in Jiuzhaigou. 解析： 表示 “某地有某物” 用 There be 句型，这里 lakes 是复数，所以用 There are “超过” 可以用 more than 或 over，这里用 more than 更通用 4.这棵树的高度达到了116.07米。 _____________________________________________________________________ 翻译：This tree reaches a height of 116.07 metres. 解析： “高度达到……” 常用 reach a height of... 小数读法：116.07 读作 one hundred and sixteen point zero seven 5.超过四分之三的人住在森林附近。 _____________________________________________________________________ 翻译：More than three-quarters of people live near forests. 解析： 分数表达：“四分之三” 写作 three-quarters（也可写为 three fourths） more than 表示 “超过”，live near... 表示 “住在…… 附近” 6. 科学家们认为在地球上生物已经存在了数百万年。（millions of） _____________________________________________________________________ 翻译：Scientists believe that living things have existed on Earth for millions of years. 解析： · 主句用一般现在时 believe，宾语从句用现在完成时 have existed，表示从过去持续到现在的动作。 millions of 后接可数名词复数，意为 “数百万的”。 7. 令我们惊讶的是，上个月我们厂的产量仅增加了百分之二。（production, increase by） _____________________________________________________________________ 翻译：To our surprise, the production of our factory only increased by 2% last month. 解析： · To one's surprise 是固定搭配，意为 “令某人惊讶的是”。 increase by + 百分比 表示 “增加了……（幅度）”；时间状语 last month 决定了句子用一般过去时 increased。 8. 泰国是我们将去参观的第二个在亚洲的国家。（be going to） _____________________________________________________________________ 翻译：Thailand is the second country in Asia that we are going to visit. 解析： · 这是一个包含定语从句的复合句，先行词 country 被序数词 the second 修饰，关系词只能用 that。 be going to 表示计划、打算做某事，主语是 we，所以用 are going to visit。 9. 火星上的重力大约是地球上的八分之三。（gravity） _____________________________________________________________________ 翻译：The gravity on Mars is about three-eighths of that on Earth. 解析： · 分数表达：分子用基数词，分母用序数词，分子大于 1 时分母加 s，所以 “八分之三” 是 three-eighths。 用 that 替代前面提到的 gravity，避免重复，这是英语中常见的比较用法。 10· 请把这张重要的通知贴在告示牌上，以便全体学生都能看到。（so that） _____________________________________________________________________ 翻译：Please put up this important notice on the bulletin board so that all the students can see it. 解析： · put up 意为 “张贴”，bulletin board 意为 “告示牌 / 公告栏”。 so that 引导目的状语从句，表示 “以便、为了”，从句中常使用 can/could/will/would 等情态动词。 话题写作 1．请以Protect Trees为题，写一篇英语短文，需满足以下要求： 1）. 词数：60词左右，书写工整，语句通顺； 2）. 内容要点：①阐述树木的重要作用（净化空气、提供氧气、美化环境、为动物提供家园）；②写出保护树木的具体做法（不砍伐树木、多植树、节约用纸）；③发出保护树木的呼吁； 3）. 语法正确，贴合本单元所学词汇、句型，不得出现真实姓名和班级。 _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【答案】例文 Protect Trees Trees are very important to us.
