If you visit the vegetable market during this time, you may see something 1 . There are often groups of vegetables that look like “ugly ducklings”. They do not look fresh and smooth. They look old and wrinkled (皱巴巴的) because of the cold frost (霜) outside. You may think these vegetables are not good to eat 2 they look ugly. However, they have a big secret (秘诀). If you taste them, they are very delicious. They taste quite sweet, almost like someone has put 3 into them! 4 are old and wrinkled vegetables sweeter than fresh and smooth ones? That’s because vegetables are 5 living things. They want to stay alive in the winter. If the water 6 their bodies turns into ice, they will die (死). So, they have a clever way to save themselves. Vegetables have something called “starch” (淀粉) inside them. When the temperature (气温) goes down, they 7 change this starch into sugar. This is very important because of an easy scientific 8 : water turns to ice very easily, but sugar water does not. By having a lot of sugar in them, the vegetables 9 it much harder for the water inside them to turn to ice. This change 10 the vegetables from the cold weather. It stops them from dying of cold.

A big panda can eat up to 38 kg of bamboo a day! But engineers (工程师) see something more. To them, bamboo is a great building material (材料). Look at the Hong Kong-Zhuhai-Macao Bridge. It is the longest sea-crossing (跨海的) bridge in the world. At its two ends, there are two man-made (人造的) islands. Many people walk and take photos there, and the floor under their feet is bamboo. It covers about 30,000 m2, as big as four football fields. Sun and sea water hit it year after year, but it stays strong. Why is bamboo so good for this job? First of all, it is very hard. Sun, rain and sea water do not hurt it easily. Second, it grows very fast. Some kinds grow up to 90 cm in one day. Third, using bamboo saves trees. It grows back quickly, so we do not need to cut down many trees to get wood. A small plant from the fields can make a big bridge a little greener. That is the power of bamboo. 1．Where is the bamboo used at the Hong Kong-Zhuhai-Macao Bridge? A．In the sea. B．On the man-made islands. C．In the pandas’ home. D．On the top of the bridge. 2．How big is the bamboo floor? A．As big as one island. B．As big as two football fields. C．As big as four football fields.

A．Food for Pandas B．A Long Sea Bridge C．A Great Building Material D．How to Take Photos B Do you know bamboo? It’s everywhere in Bali. There are 1,450 kinds of bamboo, but we only use seven kinds of them to make things. We can use bamboo to make things like beds, desks and chairs. My father uses bamboo to build Green School in Bali. In Green School, all of the rooms are made of (由……制成) bamboo. There are a lot of bamboo things in the classrooms. Every classroom has a bamboo blackboard and some bamboo desks and chairs. But every classroom has no windows, doors or walls. It only has a bamboo roof (屋顶). Green School is very nice. Students are from 40 countries. They have maths, English, art and music. In their free time, all students plant vegetables around the school. And they also keep pigs, sheep, chickens and ducks. Come and have a look at our Green School. It’s a nice school. 1．How many kinds of bamboo do we use to make things? A．7. B．14. C．40. D．1,450. 2．Where is Green School? A．In Beijing. B．In Yunnan. C．In Bali.

C ①Do you believe that trees can speak? For a long time, people thought trees were quiet and lonely, just standing in forests year after year. In fact, there is a busy world that we can’t see under the ground. It is home to roots, fungi (真菌), and many little living things. In this secret world, trees can “talk”, “help” and even “remember” in their own ways. ②When insects (昆虫) eat a tree’s leaves, the tree gives out a kind of smell. The smell is like a warning (警告) message to tell other plants, “Be careful!” Nearby trees “hear” it and produce something to make their leaves taste bad. In this way, they protect themselves before the insects come. ③Trees also have their own “Internet” like humans. Under the ground, fungi and roots connect many trees together. This is called Wood Wide Web. Through it, trees can share food and water. A big, strong tree can help smaller or younger ones when they don’t get enough sunlight or water. ④Trees are not only helpful but also clever. They can even remember things. During a dry season, they close small holes in their leaves to keep water. When rain comes back, they still grow slowly because they remember the dry time. ⑤Forests mean a lot to the Earth. When you walk in a forest, look around and listen carefully. The trees may be quiet, but their silent world has so much friendship and teamwork. 1．What is the main idea of the first paragraph? A．Trees live a quiet life in the forest. B．Fungi help trees share food and water. C．Trees are home to many small living things. D．Trees have a secret and busy life underground. 2．How do trees warn each other of danger? A．By sending smells. B．By moving roots. C．By shaking leaves. D．By making sounds. 3．What does the “Wood Wide Web” refer to (指的是)? A．A group of roots. B．An unknown website. C．A kind of fungi. D．A connection under trees. 4．What’s the structure (结构) of the passage? A． B． C． D． 5．What is the best title of the passage? A．The Secret Lives of Trees. B．The Importance of Forests. C．The Silent Growth of Plants. D．The Magic World of Insects. D ①Most people know that trees are good for us. They give us shade on sunny days and make our world beautiful with their green leaves. But trees do much more than that. They also help to make the air around us clean and healthy, which is very important for everyone. ②First, trees take in bad air and give out good air. The good air is called oxygen (氧气). We need oxygen to breathe (呼吸) and stay healthy every day. Trees make this happen quietly, all year round. They are like nature’s air cleaners. ③Second, trees can stop dust (灰尘) and small dirty things in the air. Their leaves are like small nets that catch these things. When dust comes with the wind, it gets stuck on the leaves. Later, when it rains, the water washes the dust away. This helps to keep the air clean for us to breathe. ④Third, trees can make the air cooler on hot days. When the sun is strong, trees give out water from their leaves into the air. This makes the air around them feel fresh and cool. It is nicer to walk under trees in summer because of this. ⑤Planting trees is an easy and useful way to help our Earth. Trees work hard every day to clean the air for us. We can plant trees in our school, in parks, or near our homes. Let’s plant more trees and take good care of them, because they take good care of us. 1．What is the passage mainly about? A．Why trees are beautiful. B．How trees help clean the air. C．Where to plant trees. D．What trees eat. 2．What do trees give out that we need to breathe? A．Dust. B．Shade. C．Oxygen. D．Water. 3．Why does the writer talk about “hot days” in Paragraph 4? A．To tell us to drink more water. B．To explain how trees help us feel cooler. C．To say trees need more sun in summer. D．To show that trees grow better in hot weather. 4．What can we learn from the passage? A．Trees are only useful in parks. B．Trees can help us save money. C．Planting trees is good for people and the Earth. D．Trees make the air hotter in summer. 5．What’s the structure of the passage? (①=Paragraph 1, ②=Paragraph 2…) A．①-②③④-⑤ B．①②-③④-⑤ C．①②③-④⑤ D．①-②③④⑤ 三、选词填空 阅读下面短文，在空白处填入一个适当的词或填入括号中所给单词的正确形式。 than feed from change grow wolf however plan but mean Many years ago, there were thick forests in Britain, home to many animals.

If you visit the vegetable market during this time, you may see something 1 . There are often groups of vegetables that look like “ugly ducklings”. They do not look fresh and smooth. They look old and wrinkled (皱巴巴的) because of the cold frost (霜) outside. You may think these vegetables are not good to eat 2 they look ugly. However, they have a big secret (秘诀). If you taste them, they are very delicious. They taste quite sweet, almost like someone has put 3 into them! 4 are old and wrinkled vegetables sweeter than fresh and smooth ones? That’s because vegetables are 5 living things. They want to stay alive in the winter. If the water 6 their bodies turns into ice, they will die (死). So, they have a clever way to save themselves. Vegetables have something called “starch” (淀粉) inside them. When the temperature (气温) goes down, they 7 change this starch into sugar. This is very important because of an easy scientific 8 : water turns to ice very easily, but sugar water does not. By having a lot of sugar in them, the vegetables 9 it much harder for the water inside them to turn to ice. This change 10 the vegetables from the cold weather. It stops them from dying of cold.

They look old and wrinkled...”可知，菜市场在卖不新鲜的，看起来皱巴巴的蔬菜，这是奇怪的现象。故选D。 2．句意：你可能会认为这些蔬菜因为看起来丑陋而不适合食用。 or或者；but但是；because因为；till直到。“they look ugly”是“You may think these vegetables are not good to eat”的原因，应用because引导原因状语从句。故选C。 3．句意：它们尝起来非常甜，几乎像有人往里面加了糖！ salt盐；sugar糖；milk牛奶；water水。根据“They taste quite sweet...”可知，加糖会尝起来甜。故选B。 4．句意：为什么老而皱的蔬菜比新鲜光滑的更甜？ How如何；Why为什么；What什么；Which哪一个。根据下文“That’s because...”可知，此处询问原因，应用疑问词why。故选B。 5．句意：那是因为蔬菜是聪明的生物。 colourful多彩的；large大的；smart聪明的；lovely可爱的。根据下文“In fact, they are very smart!”可知，本文讲述蔬菜聪明的一面。故选C。 6．句意：如果它们体内的水结冰，它们就会死亡。 inside在……里面；beside在……旁边；under在……下面；over在……上方。根据下文“...the water inside them to turn to ice.”可知，水是在蔬菜“体内”结冰。故选A。 7．句意：当气温下降时，它们迅速将淀粉转化为糖。 clearly清楚地；quickly迅速地；really真正地；finally最终。根据下文“...water turns to ice very easily, but sugar water does not.”可知，水很容易结冰，所以蔬菜为了存活，要快速地将淀粉转化为糖，尽早防止体内的水结冰。故选B。 8．句意：这一点非常重要，原因在于一个简单的科学事实：水很容易结冰，但糖水不会。 fact事实；plan计划；dream梦想；survey调查。根据“...water turns to ice very easily, but sugar water does not.”可知，“水很容易结冰，但糖水不会”是科学事实。故选A。 9．句意：通过体内含有大量糖分，蔬菜使得自身内部的水分更难结冰。 get得到；carry携带；keep保持；make使。根据“By having a lot of sugar in them, the vegetables...it much harder for the water inside them to turn to ice.”可知，此处指蔬菜通过糖分使自身内部的水分更难结冰。故选D。 10．句意：这种变化保护蔬菜免受寒冷天气的伤害。 protects保护；empties清空；borrows借；grows生长。根据下文“It stops them from dying of cold.”可知，这种变化让蔬菜得以免于冻死，是在保护它们，protect...from...“保护……不受……”，为固定搭配。故选A。 二、阅读理解 A You may know bamboo as pandas’ favourite food. A big panda can eat up to 38 kg of bamboo a day! But engineers (工程师) see something more. To them, bamboo is a great building material (材料). Look at the Hong Kong-Zhuhai-Macao Bridge. It is the longest sea-crossing (跨海的) bridge in the world. At its two ends, there are two man-made (人造的) islands. Many people walk and take photos there, and the floor under their feet is bamboo. It covers about 30,000 m2, as big as four football fields. Sun and sea water hit it year after year, but it stays strong. Why is bamboo so good for this job? First of all, it is very hard. Sun, rain and sea water do not hurt it easily. Second, it grows very fast. Some kinds grow up to 90 cm in one day. Third, using bamboo saves trees. It grows back quickly, so we do not need to cut down many trees to get wood. A small plant from the fields can make a big bridge a little greener. That is the power of bamboo. 1．Where is the bamboo used at the Hong Kong-Zhuhai-Macao Bridge? A．In the sea. B．On the man-made islands. C．In the pandas’ home. D．On the top of the bridge. 2．How big is the bamboo floor? A．As big as one island. B．As big as two football fields. C．As big as four football fields. D．As big as a big house. 3．Which is NOT a reason why bamboo is good for the floors? A．It is very hard. B．It grows very fast. C．It saves trees. D．It makes steel stronger. 4．What does the last sentence “A small plant can make a big bridge a little greener” mean? A．Bamboo makes the bridge turn green. B．Bamboo makes the bridge longer and longer. C．Bamboo can help the bridge and the earth be cleaner. D．Bamboo can carry cars across the sea. 5．What is the best title for the passage? A．Food for Pandas B．A Long Sea Bridge C．A Great Building Material D．How to Take Photos 【答案】1．B 2．C 3．D 4．C 5．C 【导语】本文是说明文，介绍了竹子除了是熊猫喜爱的食物外，还是出色的建筑材料；文章以港珠澳大桥人工岛的竹地板为例，说明了竹子适合作为建筑材料的三点优势，展现了竹子的环保价值。 【详解】1．细节理解题。文章第2段提到“At its two ends, there are two man-made islands. Many people walk and take photos there, and the floor under their feet is bamboo”，说明港珠澳大桥的竹子被使用在人工岛上。 2．细节理解题。根据文章第2段提到“It covers about 30,000 m², as big as four football fields”，说明竹地板的面积相当于四个足球场那么大。 3．细节理解题。文章第3段提到“First of all, it is very hard…Second, it grows very fast…Third, using bamboo saves trees”，说明竹子适合做地面的三个原因：质地坚硬、生长速度快、可以节约树木，并未提及“竹子可以让钢铁更坚固”这一内容。 4．细节理解题。文章最后一段提到“A small plant from the fields can make a big bridge a little greener. That is the power of bamboo”，结合前文提到竹子生长速度快，使用竹子可以避免砍伐大量树木，属于环保的建筑材料，因此这句话的含义是竹子作为环保材料，能够助力桥梁建设，同时让环境更清洁友好。 5．最佳标题题。全文围绕“竹子是优质建筑材料”这一核心展开，介绍了竹子在港珠澳大桥的应用以及作为建筑材料的优势，“A Great Building Material”最能概括文章核心内容。 B Do you know bamboo? It’s everywhere in Bali. There are 1,450 kinds of bamboo, but we only use seven kinds of them to make things. We can use bamboo to make things like beds, desks and chairs. My father uses bamboo to build Green School in Bali. In Green School, all of the rooms are made of (由……制成) bamboo. There are a lot of bamboo things in the classrooms. Every classroom has a bamboo blackboard and some bamboo desks and chairs. But every classroom has no windows, doors or walls. It only has a bamboo roof (屋顶). Green School is very nice. Students are from 40 countries. They have maths, English, art and music. In their free time, all students plant vegetables around the school. And they also keep pigs, sheep, chickens and ducks. Come and have a look at our Green School. It’s a nice school. 1．How many kinds of bamboo do we use to make things? A．7. B．14. C．40. D．1,450. 2．Where is Green School? A．In Beijing. B．In Yunnan.

And they also keep pigs, sheep, chickens and ducks.”，这里的“they”指代前一句的主语“all students”，即学生们也在饲养动物。 4．根据第二段描述：“Every classroom has a bamboo blackboard and some bamboo desks and chairs... It only has a bamboo roof.”以及“But every classroom has no windows, doors or walls.”，可知教室里有竹椅子（①）、竹屋顶（③）和竹桌子（④），但没有窗户（②）。因此正确组合是①③④。 5．第二段提到“My father uses bamboo to build Green School in Bali. In Green School, all of the rooms are made of bamboo.”，作者父亲能用竹子建造整个学校，说明他擅长用竹子进行建筑。 C ①Do you believe that trees can speak? For a long time, people thought trees were quiet and lonely, just standing in forests year after year. In fact, there is a busy world that we can’t see under the ground. It is home to roots, fungi (真菌), and many little living things. In this secret world, trees can “talk”, “help” and even “remember” in their own ways. ②When insects (昆虫) eat a tree’s leaves, the tree gives out a kind of smell. The smell is like a warning (警告) message to tell other plants, “Be careful!” Nearby trees “hear” it and produce something to make their leaves taste bad. In this way, they protect themselves before the insects come. ③Trees also have their own “Internet” like humans. Under the ground, fungi and roots connect many trees together. This is called Wood Wide Web. Through it, trees can share food and water. A big, strong tree can help smaller or younger ones when they don’t get enough sunlight or water. ④Trees are not only helpful but also clever. They can even remember things. During a dry season, they close small holes in their leaves to keep water. When rain comes back, they still grow slowly because they remember the dry time. ⑤Forests mean a lot to the Earth. When you walk in a forest, look around and listen carefully. The trees may be quiet, but their silent world has so much friendship and teamwork. 1．What is the main idea of the first paragraph? A．Trees live a quiet life in the forest. B．Fungi help trees share food and water. C．Trees are home to many small living things. D．Trees have a secret and busy life underground. 2．How do trees warn each other of danger? A．By sending smells. B．By moving roots. C．By shaking leaves. D．By making sounds. 3．What does the “Wood Wide Web” refer to (指的是)? A．A group of roots. B．An unknown website. C．A kind of fungi. D．A connection under trees. 4．What’s the structure (结构) of the passage? A． B． C． D． 5．What is the best title of the passage? A．The Secret Lives of Trees. B．The Importance of Forests. C．The Silent Growth of Plants. D．The Magic World of Insects. 【答案】1．D 2．A 3．D 4．C 5．A 【导语】本文是说明文，介绍树木在地下拥有隐秘的生存网络，它们能够互通警报、共享资源、留存记忆，展示树木不为人知的秘密生存方式。 【详解】1．原文第一段提到“In fact, there is a busy world that we can’t see under the ground…trees can “talk”, “help” and even “remember” in their own ways.”，第一段引出树木地下有一个隐秘且繁忙的世界。 2．原文第二段提到“the tree gives out a kind of smell. The smell is like a warning message…Nearby trees “hear” it，可知树木通过释放气味传递警告。 3．原文第三段提到“Under the ground, fungi and roots connect many trees together. This is called Wood Wide Web.”，说明了“Wood Wide Web”指地下树根与真菌搭建起来的树木之间的连接网络。 4．文章结构分析：①总起段：树木地下有隐秘世界；②③④分述：树木传递警报、地下互联网络、拥有记忆；⑤总结段：森林对地球意义重大。 结构：总——分——总（①总；②③④分；⑤总），对应图示C。 5．全文介绍树木不为人知的交流、互助、记忆等秘密生活。A项“树木的秘密生活”符合。 D ①Most people know that trees are good for us. They give us shade on sunny days and make our world beautiful with their green leaves. But trees do much more than that. They also help to make the air around us clean and healthy, which is very important for everyone. ②First, trees take in bad air and give out good air. The good air is called oxygen (氧气). We need oxygen to breathe (呼吸) and stay healthy every day. Trees make this happen quietly, all year round. They are like nature’s air cleaners. ③Second, trees can stop dust (灰尘) and small dirty things in the air. Their leaves are like small nets that catch these things. When dust comes with the wind, it gets stuck on the leaves. Later, when it rains, the water washes the dust away. This helps to keep the air clean for us to breathe. ④Third, trees can make the air cooler on hot days. When the sun is strong, trees give out water from their leaves into the air. This makes the air around them feel fresh and cool. It is nicer to walk under trees in summer because of this. ⑤Planting trees is an easy and useful way to help our Earth. Trees work hard every day to clean the air for us. We can plant trees in our school, in parks, or near our homes. Let’s plant more trees and take good care of them, because they take good care of us. 1．What is the passage mainly about? A．Why trees are beautiful. B．How trees help clean the air. C．Where to plant trees. D．What trees eat. 2．What do trees give out that we need to breathe? A．Dust. B．Shade. C．Oxygen. D．Water. 3．Why does the writer talk about “hot days” in Paragraph 4? A．To tell us to drink more water. B．To explain how trees help us feel cooler. C．To say trees need more sun in summer. D．To show that trees grow better in hot weather. 4．What can we learn from the passage? A．Trees are only useful in parks. B．Trees can help us save money. C．Planting trees is good for people and the Earth. D．Trees make the air hotter in summer. 5．What’s the structure of the passage? (①=Paragraph 1, ②=Paragraph 2…) A．①-②③④-⑤ B．①②-③④-⑤ C．①②③-④⑤ D．①-②③④⑤ 【答案】1．B 2．C 3．B 4．C 5．A 【导语】本文主要介绍了树木对净化空气和环境的重要作用，分别从产生氧气、阻挡灰尘和夏季降温三个方面具体阐述，最后呼吁人们植树护树。 【详解】1．根据第一段中的“But trees do much more than that. They also help to make the air around us clean and healthy, which is very important for everyone.”以及后文分别阐述树木的三种净化作用可知，文章主要介绍了树木如何帮助净化空气。 2．根据第二段中的“First, trees take in bad air and give out good air. The good air is called oxygen (氧气). We need oxygen to breathe (呼吸) and stay healthy every day.”可知，树木释放出我们呼吸所需要的氧气。 3．根据第四段中的“Third, trees can make the air cooler on hot days. When the sun is strong, trees give out water from their leaves into the air. This makes the air around them feel fresh and cool.”可知，第四段中心是树木在炎热天气降温，举热天例子解释树木如何让空气变凉爽，即作者提到“hot days”是为了解释树木如何帮助人们感觉凉爽。 4．根据第五段中的“Planting trees is an easy and useful way to help our Earth. Trees work hard every day to clean the air for us.”以及全文可知，植树对人类和地球都有益。 5．通读文章可知：第①段为总起：引入主题，指出树木能净化空气；第②、③、④段分别用“First, Second, Third”并列说明了树木净化空气的三个不同具体作用；第⑤段为总结：提出倡议，呼吁植树。其篇章结构为“总-分-总”，即①-②③④-⑤，对应选项A。 三、选词填空 阅读下面短文，在空白处填入一个适当的词或填入括号中所给单词的正确形式。 than feed from change grow wolf however plan but mean Many years ago, there were thick forests in Britain, home to many animals.

Now Britain's population is more than 67 million.Three-quarters of Britain is fields, towns or cities. Although 25% of the land is the countryside, there are fewer small animals 4 ever before. Britain is one of the few countries in the world without a large wild animal 5 on meat. Some people want to 6 this.Some say that Britain needs to become more natural again and they suggest trees and plants that once 7 in Britain should be allowed to grow again. They even say that people should help large wild animals which have not lived in Britain to return and live in the wild. Not everyone agrees. In the last twenty years, people have planted over one million trees and there are 8 for more—— but how about wild animals? Some people ask if wolves will attack sheep or even humans.They are also angry that rewilding might 9 an end to walking in the hills.
