They produce tea, which is very popular around the world. Tea trees are important because they take in carbon dioxide and use it to produce oxygen, making the air fresh. They also make our lives more convenient by providing us with delicious tea. To protect tea trees, we should plant more of them and stop cutting them down without reason. Let’s work together to keep these wonderful trees alive!

If so, when you eat next time, take a look at them. Are they really blue? Not really. Take off the skin (表皮). The inside is white. Rub (摩擦) the inside of a blueberry on a piece of white paper. It gets reddish-purple. And if you rub the outside of a blueberry on it, it gets almost black. But the moment you pick one, it does look blue. Why? ①The first way is through “structural colour” (结构色). ②The blueberry makes “structural colour” in its own way. ③When the blueberry is full-grown, it is black. ④But a thin layer of wax (蜡层) on the outside of the blueberry gives it a blue look. The second is through plant pigments (色素). The pigments on the blueberry skin take in the green and yellow light and reflect (反射) the blue light. That’s why blueberries look blue in our eyes.

Then the God pulled the tree out and planted it upside down (颠倒；倒转) to make sure it stayed in one place. What’s the tree? It’s the Baobab tree, also called monkey bread tree, bottle tree or others. The Baobab tree is a strange looking tree that grows in Africa and Australia. Just like its name “Bottle Tree”, it looks like a large bottle. Some grow as tall as a 16-floor building. During the dry season, these trees are standing there without leaves, and look like trunks (树干) sticking up in the air. But when the rainy season comes, leaves appear and then flowers come out. Later the flowers can turn into fruit. Baobab is called “the tree of life” because it can live longer than 1000 years old. In the dry land, the baobab can pull in and hold 3790 liters (升) of water. Thirsty people can drink the water stored in the tree. The fruit, monkey bread, is good to eat. Baobab leaves are a kind of medicine (药). People can use the bark (树皮) to make paper or cloth. When a baobab gets old, its trunk becomes hollow (空心的). An old tree can hold many people. The local people often build their houses inside these trunks. It is such a useful tree, some people could hardly live without it. 31．How does the writer begin the text? A．By asking a question. B．By telling a story. C．By singing a song. D．By giving an example. 32．Where does the Baobab tree grow according to the passage? A．Asia and Africa. B．Africa and Australia. C．Asia and Europe. D．Australia and Europe. 33．Why is the Baobab tree called “the tree of life”? A．Because it can live over 1000 years and provide water, food, and medicine. B．Because it looks like a large bottle. C．Because it has beautiful flowers in rainy seasons. D．Because its trunk can hold many people. 34．What can local people do with the hollow trunk of an old Baobab tree? A．Grow other plants. B．Make paper or cloth. C．Build houses inside it. D．Make furniture (家具). 35．What’s the best title of the passage? A．God and Baobab B．Baobab’s Hollow C．Baobab’s Trunk, Leaves and Fruit D．A Special Tree-Baobab 【答案】31．B 32．B 33．A 34．C 35．D 【导语】本文主要介绍了非洲和澳洲的一种特殊树木——猴面包树，包括它的传说、外形特点、用途以及被称为“生命之树”的原因。 31．根据文章开头“Long ago, when the God first planted a tree in the garden...”可知，作者以讲述一个关于上帝种树的故事来开头。 32．根据文章第二段“The Baobab tree is a strange looking tree that grows in Africa and Australia.”可知，猴面包树生长在非洲和澳大利亚。 33．根据文章第三段“Baobab is called ‘the tree of life’ because it can live longer than 1000 years old... hold 3790 liters of water... The fruit... is good to eat. Baobab leaves are a kind of medicine.”可知，它能活千年以上，还能提供水、食物和药材，因此被称为“生命之树”。 34．根据文章第三段“The local people often build their houses inside these trunks.”可知，当地人会在空心的树干里建造房屋。 35．全文围绕猴面包树的传说、外形、生长地、用途等方面进行介绍，突出它是一种特殊的树。 D Did you take part in any tree-planting activities this past March 12? Or maybe you went to check out the little tree you planted a few years ago? Standing beside it, you might have been amazed at how much it has changed. It’s really great to watch a tree grow year by year. Even the tallest ones of them grow from tiny seeds (种子). Have you ever wondered how? A full-grown tree may drop hundreds or even thousands of seeds a year. Inside each seed is something called an embryo(胚). Think of it as a small group of cells (细胞). These cells are ready to form roots, stems (茎), and first leaves. Once the covering around the seed gets wet, the embryo cells, which have been patiently waiting, suddenly come to life. They start to grow and break out. This is called germination. First, the roots develop and push out and down into the soil. This makes sure the new plant can get water from the soil. Then the stem grows up and makes the first leaves. As these leaves produce “food” in the sunlight, the plant gets the energy to grow more new leaves. Let’s imagine you drive a nail (钉子) into a tree at one metre above the ground. What will you see when you come back in ten years? The tree will be much taller, but the nail will still be only one metre above the ground. That’s because trees get taller by growing upwards from the top. At the same time, their trunk gets thicker by growing outwards. It is like the tree has two different ways of growing at the same time. The upward growth is like a race towards the sky, reaching for more sunlight, while the outward growth of the trunk is like adding more and more rings of protection and support. As trees get older, they continue to grow taller and thicker. Guess how tall the world’s tallest living tree is? Over 110 metres! That’s as tall as a 30-floor building! Isn’t it amazing? 36．Which one of the pictures shows the stage of germination? A． B． C． D． 37．Why does the writer use the example of driving a nail into a tree in Paragraph 4? A．To explain why people put nails in trees. B．To help readers understand how trees grow taller. C．To show that nails don’t stop trees from growing. D．To teach readers a way to record the growth of trees. 38．If a tree trunk gets thicker over time, what will happen to a metal ring (金属环) put around the bottom of the trunk after 10 years? A．The metal ring will go into the soil. B．The metal ring will be higher off the ground. C．The metal ring will move up and down along the trunk. D．The metal ring will stay at the same height but may embed (嵌入) in the tree. 39．From the article, we can find the answer to the question “__________” ①How do trees get water from the soil? ②Why does a nail in a tree trunk stay at the same height over time? ③How many seeds does a full-grown tree drop in its lifetime? ④How tall can the tallest trees in the world grow? ⑤How long does a seed take to grow leaves? A．①③④ B．①②③ C．②④⑤ D．①②④ 40．Which of the following best represents the structure of the passage? A．Tell stories → List facts → Give a warning B．Ask questions → Explain steps → Share a fact C．List problems → Study reasons → Offer advice D．Share experiences → Show examples → Introduce features 【答案】36．A 37．B 38．D 39．D 40．B 【导语】本文是一篇说明文，通过提问和举例的方式，生动地解释了树木的生长过程，包括种子发芽、树木长高和长粗的机制，以及世界上最高树木的高度。 36．第三段描述萌发阶段：“This is called germination. First, the roots develop…Then the stem grows up and makes the first leaves”，这说明萌发先长根、再长茎叶，对应图A。 37．第四段以钉钉子为例：“…the tree will be much taller, but the nail will still be only one metre above the ground. That’s because trees get taller by growing upwards from the top”，结合该内容可推知，作者用这个例子直观解释树木长高是从顶端向上生长，因此钉子高度不会随树木长高而改变，以此帮助读者理解树木长高的机制。 38．第四段说明树干变粗带来的影响：“their trunk gets thicker by growing outwards…the outward growth of the trunk is like adding more and more rings of protection and support”，这说明树干会向外生长变粗，可推知金属环高度不变，但会被嵌入树干。 39．第三段说明树木如何吸水：“the roots develop…This makes sure the new plant can get water from the soil.”对应问题①；第四段通过钉子的例子，说明钉子高度不变的原因，对应问题②；第五段指出最高树的高度：“Guess how tall the world’s tallest living tree is? Over 110 metres!”对应问题④。其他问题文中未提及。 40．文章结构为：开头提问（如“Have you ever wondered how?”）→解释步骤（如种子发芽、树木生长机制）→分享事实（如最高树木的高度）。 四、阅读还原(本大题共5小题，每小题1分，共5分) 阅读短文，从方框中选出合适的句子将短文补充完整。 Rice is a very common kind of food in life.

Every late autumn, its leaves would all turn bright yellow, which makes the tree look like wearing a “golden coat”. When watched from a distance (距离), the old ginkgo tree looks like it is decorated with countless strings of golden firecrackers. As a result, it attracts (吸引) a lot of tourists from both home and abroad every year. What’s more mysterious (神秘的) about this ginkgo tree is that some people believe Emperor Taizong of the Tang Dynasty planted it, and it is still lush (茂盛的) and full of energy after 1,400 years. The ginkgo tree is one of China’s most famous ancient trees and one of the oldest tree species in the world. The earliest discovered fossils (化石) of this type of tree date back to around 300 million years ago, which is why this tree is also known as a “living fossil”. Though there are many ginkgo trees, ancient ginkgo trees are quite rare (罕见的). The fruits they bear, known as “white nuts”, are much higher in nutritional (营养的) value compared with common ginkgo nuts, making them very valuable. They are considered a “national treasure” of China. 46．Why do tourists from all over the world visit the old ginkgo tree? (within 6 words) 47．What is the mystery about the old ginkgo tree? 48．What do you think of this ginkgo tree compared with the ginkgo trees in our school? (from 2 sides) 49．Why does the writer mention “white nuts” of this ginkgo tree? 50．Name another national treasure and explain the reason. 【答案】46．For/Because of its beauty/its beautiful looks/appearance. /Because it’s beautiful. 47．Who planted it?/ Did Emperor Taizong plant it?/ Why is it still lush and full of energy after 1,400 years?/Was it planted by Emperor Taizong? / The mystery is that Emperor Taizong of the Tang Dynasty planted it. / People don’t know who planted it / Why it’s still lush and full of energy after 1,400 years. 48．It’s older/ more beautiful, more ancient, and more mysterious/ famous. 49．To show their value/ To show they’re valuable. / To show they’re much higher in nutritional value. 50．The panda/ Pandas. Because they are/it’s a symbol of China/ the most popular animal / very popular / loved by many people. 【导语】本文主要介绍了西安古观音禅寺的千年银杏树，讲述了它秋日的绝美景观、相传由唐太宗亲手栽种的神秘来历，以及它作为“活化石”和“国宝”的珍贵价值。 46．根据“Every late autumn, its leaves would all turn bright yellow, which makes the tree look like wearing a ‘ golden coat’...As a result, it attracts (吸引) a lot of tourists from both home and abroad every year.”可知，这棵银杏树深秋时满树黄叶，远看像挂满金鞭炮，因此吸引了大量游客。故填For/Because of its beauty/its beautiful looks/appearance. /Because it’s beautiful. 47．根据“What’s more mysterious about this ginkgo tree is that some people believe Emperor Taizong Tang Dynasty planted it”可知，这棵树的神秘之处在于，相传它是由唐太宗亲手栽种的，历经1400年依然枝繁叶茂。故填Who planted it?/ Did Emperor Taizong plant it?/ Why is it still lush and full of energy after 1,400 years?/Was it planted by Emperor Taizong? / The mystery is that Emperor Taizong in Tang Dynasty planted it. / People don’t know who planted it / Why it’s still lush and full of energy after 1,400 years. 48．开放性回答。参考答案为：It’s older/ more beautiful, more ancient, and more mysterious/ famous.（答案不唯一，合理即可） 49．根据“Though there are many ginkgo trees, ancient ginkgo trees are quite rare (罕见的)....They are considered ‘national treasure’ of China.”可知，这棵古银杏树结的白果营养价值远超普通银杏果，十分珍贵。作者提及白果，是为了体现这棵古树的价值，进一步说明它被称为“国宝”的原因。故填To show their value/ To show they’re valuable. / To show they’re much higher in nutritional value. 50．开放性回答。参考答案为：The panda/ Pandas. Because they are/it’s a symbol of China/ the most popular animal / very popular / loved by many people.（答案不唯一，合理即可） 六、短文填空(本大题共10小题，每小题1分，共10分) 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。 Plants are our friends, even the tiniest grass.

And a lot of people would like to buy tomatoes when they are shopping. However, do you know more about tomatoes? Their two colours often tell you how different they are. Green means that you need to leave and find other tomatoes. When they are red, you can pick and eat them without peeling. Also, you can use them to make many different kinds of delicious dishes, such as scrambled eggs with tomatoes (西红柿炒鸡蛋), tomato and egg noodles, stewed beef with tomato (西红柿炖牛肉). If you think these dishes are difficult to cook, you can just cut two tomatoes into pieces and add some sugar to them. They are also very delicious. Many people even grow lots of tomatoes in their gardens. Why? Because tomatoes are very versatile (多用途的). It is a kind of vegetable, but you can think of it as a kind of fruit. It not only gives people lots of vitamin (维生素) C, but also helps people keep healthy.

And if you rub the outside of a blueberry on it, it gets almost black. But the moment you pick one, it does look blue. Why? ①The first way is through “structural colour” (结构色). ②The blueberry makes “structural colour” in its own way. ③When the blueberry is full-grown, it is black. ④But a thin layer of wax (蜡层) on the outside of the blueberry gives it a blue look. The second is through plant pigments (色素). The pigments on the blueberry skin take in the green and yellow light and reflect (反射) the blue light. That’s why blueberries look blue in our eyes. In fact, there isn’t any “true blue” in the plants. We can also see the similar features (特点) on the green leaves. The blueberry’s special colour is cool. It shows nature’s magic.

C Long ago, when the God first planted a tree in the garden, it was full of energy and kept moving. Then the God pulled the tree out and planted it upside down (颠倒；倒转) to make sure it stayed in one place. What’s the tree? It’s the Baobab tree, also called monkey bread tree, bottle tree or others. The Baobab tree is a strange looking tree that grows in Africa and Australia. Just like its name “Bottle Tree”, it looks like a large bottle. Some grow as tall as a 16-floor building. During the dry season, these trees are standing there without leaves, and look like trunks (树干) sticking up in the air. But when the rainy season comes, leaves appear and then flowers come out. Later the flowers can turn into fruit. Baobab is called “the tree of life” because it can live longer than 1000 years old. In the dry land, the baobab can pull in and hold 3790 liters (升) of water. Thirsty people can drink the water stored in the tree. The fruit, monkey bread, is good to eat. Baobab leaves are a kind of medicine (药). People can use the bark (树皮) to make paper or cloth. When a baobab gets old, its trunk becomes hollow (空心的). An old tree can hold many people. The local people often build their houses inside these trunks. It is such a useful tree, some people could hardly live without it. 31．How does the writer begin the text? A．By asking a question. B．By telling a story. C．By singing a song. D．By giving an example. 32．Where does the Baobab tree grow according to the passage? A．Asia and Africa. B．Africa and Australia. C．Asia and Europe. D．Australia and Europe. 33．Why is the Baobab tree called “the tree of life”? A．Because it can live over 1000 years and provide water, food, and medicine. B．Because it looks like a large bottle. C．Because it has beautiful flowers in rainy seasons. D．Because its trunk can hold many people. 34．What can local people do with the hollow trunk of an old Baobab tree? A．Grow other plants. B．Make paper or cloth. C．Build houses inside it. D．Make furniture (家具). 35．What’s the best title of the passage? A．God and Baobab B．Baobab’s Hollow C．Baobab’s Trunk, Leaves and Fruit D．A Special Tree-Baobab D Did you take part in any tree-planting activities this past March 12? Or maybe you went to check out the little tree you planted a few years ago? Standing beside it, you might have been amazed at how much it has changed. It’s really great to watch a tree grow year by year. Even the tallest ones of them grow from tiny seeds (种子). Have you ever wondered how? A full-grown tree may drop hundreds or even thousands of seeds a year. Inside each seed is something called an embryo(胚). Think of it as a small group of cells (细胞). These cells are ready to form roots, stems (茎), and first leaves. Once the covering around the seed gets wet, the embryo cells, which have been patiently waiting, suddenly come to life. They start to grow and break out. This is called germination. First, the roots develop and push out and down into the soil. This makes sure the new plant can get water from the soil. Then the stem grows up and makes the first leaves. As these leaves produce “food” in the sunlight, the plant gets the energy to grow more new leaves. Let’s imagine you drive a nail (钉子) into a tree at one metre above the ground. What will you see when you come back in ten years? The tree will be much taller, but the nail will still be only one metre above the ground. That’s because trees get taller by growing upwards from the top. At the same time, their trunk gets thicker by growing outwards. It is like the tree has two different ways of growing at the same time. The upward growth is like a race towards the sky, reaching for more sunlight, while the outward growth of the trunk is like adding more and more rings of protection and support. As trees get older, they continue to grow taller and thicker. Guess how tall the world’s tallest living tree is? Over 110 metres! That’s as tall as a 30-floor building! Isn’t it amazing? 36．Which one of the pictures shows the stage of germination? A． B． C． D． 37．Why does the writer use the example of driving a nail into a tree in Paragraph 4? A．To explain why people put nails in trees. B．To help readers understand how trees grow taller. C．To show that nails don’t stop trees from growing. D．To teach readers a way to record the growth of trees. 38．If a tree trunk gets thicker over time, what will happen to a metal ring (金属环) put around the bottom of the trunk after 10 years? A．The metal ring will go into the soil. B．The metal ring will be higher off the ground. C．The metal ring will move up and down along the trunk. D．The metal ring will stay at the same height but may embed (嵌入) in the tree. 39．From the article, we can find the answer to the question “__________” ①How do trees get water from the soil? ②Why does a nail in a tree trunk stay at the same height over time? ③How many seeds does a full-grown tree drop in its lifetime? ④How tall can the tallest trees in the world grow? ⑤How long does a seed take to grow leaves? A．①③④ B．①②③ C．②④⑤ D．①②④ 40．Which of the following best represents the structure of the passage? A．Tell stories → List facts → Give a warning B．Ask questions → Explain steps → Share a fact C．List problems → Study reasons → Offer advice D．Share experiences → Show examples → Introduce features 四、阅读还原(本大题共5小题，每小题1分，共5分) 阅读短文，从方框中选出合适的句子将短文补充完整。 Rice is a very common kind of food in life.

And a lot of people would like to buy tomatoes when they are shopping. However, do you know more about tomatoes? Their two colours often tell you how different they are. Green means that you need to leave and find other tomatoes. When they are red, you can pick and eat them without peeling. Also, you can use them to make many different kinds of delicious dishes, such as scrambled eggs with tomatoes (西红柿炒鸡蛋), tomato and egg noodles, stewed beef with tomato (西红柿炖牛肉). If you think these dishes are difficult to cook, you can just cut two tomatoes into pieces and add some sugar to them. They are also very delicious. Many people even grow lots of tomatoes in their gardens. Why? Because tomatoes are very versatile (多用途的). It is a kind of vegetable, but you can think of it as a kind of fruit. It not only gives people lots of vitamin (维生素) C, but also helps people keep healthy.

And if you rub the outside of a blueberry on it, it gets almost black. But the moment you pick one, it does look blue. Why? ①The first way is through “structural colour” (结构色). ②The blueberry makes “structural colour” in its own way. ③When the blueberry is full-grown, it is black. ④But a thin layer of wax (蜡层) on the outside of the blueberry gives it a blue look. The second is through plant pigments (色素). The pigments on the blueberry skin take in the green and yellow light and reflect (反射) the blue light. That’s why blueberries look blue in our eyes. In fact, there isn’t any “true blue” in the plants. We can also see the similar features (特点) on the green leaves. The blueberry’s special colour is cool. It shows nature’s magic.

C Long ago, when the God first planted a tree in the garden, it was full of energy and kept moving. Then the God pulled the tree out and planted it upside down (颠倒；倒转) to make sure it stayed in one place. What’s the tree? It’s the Baobab tree, also called monkey bread tree, bottle tree or others. The Baobab tree is a strange looking tree that grows in Africa and Australia. Just like its name “Bottle Tree”, it looks like a large bottle. Some grow as tall as a 16-floor building. During the dry season, these trees are standing there without leaves, and look like trunks (树干) sticking up in the air. But when the rainy season comes, leaves appear and then flowers come out. Later the flowers can turn into fruit. Baobab is called “the tree of life” because it can live longer than 1000 years old. In the dry land, the baobab can pull in and hold 3790 liters (升) of water. Thirsty people can drink the water stored in the tree. The fruit, monkey bread, is good to eat. Baobab leaves are a kind of medicine (药). People can use the bark (树皮) to make paper or cloth. When a baobab gets old, its trunk becomes hollow (空心的). An old tree can hold many people. The local people often build their houses inside these trunks. It is such a useful tree, some people could hardly live without it. 31．How does the writer begin the text? A．By asking a question. B．By telling a story. C．By singing a song. D．By giving an example. 32．Where does the Baobab tree grow according to the passage? A．Asia and Africa. B．Africa and Australia. C．Asia and Europe. D．Australia and Europe. 33．Why is the Baobab tree called “the tree of life”? A．Because it can live over 1000 years and provide water, food, and medicine. B．Because it looks like a large bottle. C．Because it has beautiful flowers in rainy seasons. D．Because its trunk can hold many people. 34．What can local people do with the hollow trunk of an old Baobab tree? A．Grow other plants. B．Make paper or cloth. C．Build houses inside it. D．Make furniture (家具). 35．What’s the best title of the passage? A．God and Baobab B．Baobab’s Hollow C．Baobab’s Trunk, Leaves and Fruit D．A Special Tree-Baobab D Did you take part in any tree-planting activities this past March 12? Or maybe you went to check out the little tree you planted a few years ago? Standing beside it, you might have been amazed at how much it has changed. It’s really great to watch a tree grow year by year. Even the tallest ones of them grow from tiny seeds (种子). Have you ever wondered how? A full-grown tree may drop hundreds or even thousands of seeds a year. Inside each seed is something called an embryo(胚). Think of it as a small group of cells (细胞). These cells are ready to form roots, stems (茎), and first leaves. Once the covering around the seed gets wet, the embryo cells, which have been patiently waiting, suddenly come to life. They start to grow and break out. This is called germination. First, the roots develop and push out and down into the soil. This makes sure the new plant can get water from the soil. Then the stem grows up and makes the first leaves. As these leaves produce “food” in the sunlight, the plant gets the energy to grow more new leaves. Let’s imagine you drive a nail (钉子) into a tree at one metre above the ground. What will you see when you come back in ten years? The tree will be much taller, but the nail will still be only one metre above the ground. That’s because trees get taller by growing upwards from the top. At the same time, their trunk gets thicker by growing outwards. It is like the tree has two different ways of growing at the same time. The upward growth is like a race towards the sky, reaching for more sunlight, while the outward growth of the trunk is like adding more and more rings of protection and support. As trees get older, they continue to grow taller and thicker. Guess how tall the world’s tallest living tree is? Over 110 metres! That’s as tall as a 30-floor building! Isn’t it amazing? 36．Which one of the pictures shows the stage of germination? A． B． C． D． 37．Why does the writer use the example of driving a nail into a tree in Paragraph 4? A．To explain why people put nails in trees. B．To help readers understand how trees grow taller. C．To show that nails don’t stop trees from growing. D．To teach readers a way to record the growth of trees. 38．If a tree trunk gets thicker over time, what will happen to a metal ring (金属环) put around the bottom of the trunk after 10 years? A．The metal ring will go into the soil. B．The metal ring will be higher off the ground. C．The metal ring will move up and down along the trunk. D．The metal ring will stay at the same height but may embed (嵌入) in the tree. 39．From the article, we can find the answer to the question “__________” ①How do trees get water from the soil? ②Why does a nail in a tree trunk stay at the same height over time? ③How many seeds does a full-grown tree drop in its lifetime? ④How tall can the tallest trees in the world grow? ⑤How long does a seed take to grow leaves? A．①③④ B．①②③ C．②④⑤ D．①②④ 40．Which of the following best represents the structure of the passage? A．Tell stories → List facts → Give a warning B．Ask questions → Explain steps → Share a fact C．List problems → Study reasons → Offer advice D．Share experiences → Show examples → Introduce features 四、阅读还原(本大题共5小题，每小题1分，共5分) 阅读短文，从方框中选出合适的句子将短文补充完整。 Rice is a very common kind of food in life.

Every late autumn, its leaves would all turn bright yellow, which makes the tree look like wearing a “golden coat”. When watched from a distance (距离), the old ginkgo tree looks like it is decorated with countless strings of golden firecrackers. As a result, it attracts (吸引) a lot of tourists from both home and abroad every year. What’s more mysterious (神秘的) about this ginkgo tree is that some people believe Emperor Taizong of the Tang Dynasty planted it, and it is still lush (茂盛的) and full of energy after 1,400 years. The ginkgo tree is one of China’s most famous ancient trees and one of the oldest tree species in the world. The earliest discovered fossils (化石) of this type of tree date back to around 300 million years ago, which is why this tree is also known as a “living fossil”. Though there are many ginkgo trees, ancient ginkgo trees are quite rare (罕见的). The fruits they bear, known as “white nuts”, are much higher in nutritional (营养的) value compared with common ginkgo nuts, making them very valuable. They are considered a “national treasure” of China. 46．Why do tourists from all over the world visit the old ginkgo tree? (within 6 words) 47．What is the mystery about the old ginkgo tree? 48．What do you think of this ginkgo tree compared with the ginkgo trees in our school?

It’s hard to imagine living without plants. Plants make our world more 51 (live). They provide us with oxygen, food, and even 52 (material) like bamboo. We use these to make furniture, paper and more. Without plants, life on earth would be 53 (possible). They play an important role in our world. One fantastic process (过程) in plants is pollination. Bees, butterflies, and even the wind help plants reproduce (繁殖) by 54 (carry) pollen from one flower to another. This is crucial (至关重要的) for the 55 (grow) of fruits and seeds. In order to live, plants need protection from pests and harsh weather. Some plants have special ways to protect 56 (them), like thorns or bitter-tasting leaves. Plants are also of great 57 (important) in fighting climate change. They absorb tons of carbon dioxide, a gas that contributes to global warming. By planting more trees and protecting more forests, we can improve the climate and make a 58 (health) planet. Actually, plants are truly 59 (amazingly). I’m disappointed that some of them are in danger.
