Everyone should try their best to protect trees. First, try to save trees in the area where you live. Generally, large, old trees can better help improve the environment (保护环境) than small, young trees. That’s why it’s important to save as many older trees as possible. When you see a tree getting cut down, try to find out why. Sometimes trees are destroyed or diseased (被破坏或患病), so they need to be cut down. Otherwise, it’s still possible to save the tree. Planting enough new trees can also help. You should plant trees that are native to your area so that they can grow big enough easily to clean the air and water. Second, change (改变) your living habits. People cut down millions of trees each year to keep the paper industry (造纸工业) going, so using fewer paper products in your daily life can help save trees. For example, use cloth towels instead of paper towels. If you must use paper products, always buy the recycled ones. Eating less beef can also help protect trees. It may seem strange to most people, but you should know that people are cutting down rainforest trees so that people can have land to keep more cattle. 1．We can know that trees are ______ from Paragraph 1. A．beautiful B．dangerous C．important D．unusual 2．Why is it important to save as many older trees as possible? A．Because they look better than small young trees. B．Because they can help people make more money. C．Because they can do better in improving the environment. D．Because they make cleaner oxygen. 3．When you see someone cutting down a tree, you should ______. A．stop him as soon as possible B．try to find out why he is cutting down the tree C．try to help him D．make a plan to plant a new tree 4．If you want to help save trees, you should try to ______ in daily life. A．eat less meat B．use paper bags C．eat more beef D．use cloth towels 5．Which is the best title for the passage? A．Ways to save trees B．Trees in our daily lives C．Changing habit helps save trees D．Plant more trees to save the Earth 【答案】1．C 2．C 3．B 4．D 5．A 【导语】本文主要介绍了拯救树木的方法。 1．推理判断题。根据“Trees clean the air, soil and water, making the Earth a better place for us to live in”可知树木净化空气、土壤和水，使地球成为我们生活的更好地方，可见树木非常重要。故选C。 2．细节理解题。根据“large, old trees can better help improve the environment (保护环境) than small, young trees”可知高大的老树比矮小的小树更有助于改善环境。故选C。 3．细节理解题。根据“When you see a tree getting cut down, try to find out why”可知当你看到一棵树被砍倒时，试着找出原因。故选B。 4．细节理解题。根据“For example, use cloth towels instead of paper towels”可知用布毛巾代替纸巾，可以帮助拯救树木。故选D。 5．最佳标题题。本文主要介绍了拯救树木的方法，以选项A“拯救树木的方法”为标题最合适。故选A。 Why do the leaves on trees have different colors? What makes them change color? Leaves use sunlight, water, and air to make food for the trees. This way of making food is called photosynthesis. Photosynthesis is important to animals as well as plants. Some animals eat plants. Other animals eat these animals. Summer is playtime. For the leaves of many trees, however, it’s work, work, work! The Sun is shining. The leaves are making food for the trees. The trees keep more than enough food deep inside. Leaves are green in summer because they are making food. Leaves also have orange, yellow, or brown colors inside them. During summer, those colors are covered by the green color. Many places get colder in autumn with shorter days and longer nights. Trees get less sunlight, so photosynthesis slows down. Over time, leaves stop making the green chemical (化学物质). The orange, yellow, and brown colors grow when that happens. Once it gets cold enough and ice appears at night, the trees drop their leaves. They do this to keep themselves safe. If the leaves turn to ice while still on the trees, the trees can be hurt. Trees that drop their leaves are bare (光秃秃) in winter. They use the food they save in summer to get through the cold days and nights. Spring comes before long. Ice and snow disappear and the rains come. The Sun shines, and tiny leaves grow from branches. Once again, the leaves use sunlight, water, and air to make food. The cycle begins again. 1．What is photosynthesis according to the passage? A．It is a way of growing leaves. B．It is a way of changing colors. C．It is a way to make food for plants. D．It is a way for animals to eat plants. 2．Why are leaves green in summer? A．Because trees are making food for leaves. B．Because summer is playtime for the leaves of many trees. C．Because there is no other color inside leaves in summer. D．Because they are busy making food for trees. 3．What stops leaves from making the green chemical in autumn? A．Less air in autumn. B．Less sunlight in autumn. C．Less water in autumn. D．Less time in autumn. 4．What does the underlined word “They” in Paragraph 4 refer to? A．The trees. B．The leaves. C．The colors. D．The animals. 5．What is the best title of the passage? A．The importance of the sunlight. B．The trees in different seasons. C．The colors of the tree leaves. D．The changes of the four seasons. 【答案】1．C 2．D 3．B 4．A 5．C 【导语】本文主要介绍了树叶之所以会变色，是因为它们通过光合作用制造食物。 1．细节理解题。根据“This way of making food is called photosynthesis.”可知，光合作用是植物制作食物的方法。故选C。 2．细节理解题。根据“Leaves are green in summer because they are making food.”可知，树叶在夏天是绿色的，因为它们正在为树制造食物。故选D。 3．细节理解题。根据“Trees get less sunlight, so photosynthesis slows down.”可知，秋天树叶停止产生绿色化学物质是因为阳光减少。故选B。 4．词句猜测题。根据“Once it gets cold enough and ice appears at night, the trees drop their leaves. They do this to keep themselves safe. If the leaves turn to ice while still on the trees, the trees can be hurt.”可知，一旦天气变得足够冷，晚上开始结冰，树木就会落叶。它们这样做是为了保证自己的安全。如果树叶还挂在树上就结冰了，那么树木就会受到伤害。所以they指的是树木，故选A。 5．最佳标题题。根据“Why do the leaves on trees have different colors? What makes them change color?”及通读全文可知，本文主要介绍了树叶的颜色及为什么会变色，故“树叶的颜色”符合本文标题。故选C。 Spring is a good time to start planning a vegetable or flower garden. Here is some fun work to do before you are ready to put your first plants in the ground. ※ Think about a theme If you have not decided what you want to plant in your garden, you can use a theme to guide you.

Some scientists find that trees can really “talk”! ②Some trees use chemicals (化学物质) to talk. When insects attack them, they gives out chemicals from the leaves. This is like a call for help, “I’m being attacked!” Some of these chemicals drive insects away. Others can call birds to come to kill the insects. Scientists hope to learn more about this, so that we can use it to keep insects away from crops like rice. ③More surprisingly, trees also use sound to talk. People can’t hear these sounds, but trees are making them. Some plants make noises with their roots. Some trees make noises when there is not enough water. ④Most surprisingly of all, trees have an “Internet” to give out and get information in a big forest. Scientists call it the “Wood Wide Web” (树联网). The fungi (真菌) underground help build up the “Wood Wide Web” among the roots of different trees. It is just like the Internet we use. Using the “Wood Wide Web”, trees can share information and even food with each other. However, it may also be harmful. Some trees may use it to take too much food from others, or give out chemicals to hurt other plants. Perhaps one day scientists will learn how to build a “Great Wall” to help stop these. ⑤Trees talk to each other in different ways. Now, scientists are learning more about these ways and maybe one day we will be able to “talk” with trees ourselves. 1．Trees can “talk” in different ways. How many ways does the passage show? ________ A．One. B．Two. C．Three. D．Four. 2．What does the word “attack” mean in paragraph 2?  ________ A．Hurt. B．Burn. C．Protect. D．Catch. 3．Why may trees make noise according to paragraph 3?  ________ A．They want to use chemicals. B．They need more water to keep alive. C．They would like to share information. D．They hope people to hear their sound. 4．If there is no rain for a long time, what disadvantages (坏处) may the “Wood Wide Web” bring?  ________ A．Insects may eat more leaves. B．Fungi may not be able to work. C．Some tees may take in water from others. D．Scientists may build up a wall in the forest. 5．What is the structure of the passage?  ________ A． B． C． D． 【答案】1．C 2．A 3．B 4．C 5．A 【导语】本文是一篇说明文，主要讲了树以不同的方式相互交流。 1．细节理解题。根据第二段“Some trees use chemicals (化学物质) to talk. ”、第三段“More surprisingly, trees also use sound to talk. ”和第四段“Most surprisingly of all, trees have an “Internet” to give out and get information in a big forest.”可知树可以通过化学物质、声音和树联网“说话”，文章共展示了三种方式。故选C。 2．词义猜测题。根据第二段“When insects attack them, they gives out chemicals from the leaves.”可知它们呼救是因为它们受到了伤害，所以推测attack是“攻击、伤害”与hurt同义。故选A。 3．细节理解题。根据第三段“Some trees make noises when there is not enough water.”可知一些树发出声音是需要水。故选B。 4．细节理解题。根据第四段“However, it may also be harmful. Some trees may use it to take too much food from others, or give out chemicals to hurt other plants. ”可推测当缺水时，一些树可能会汲取别的树的水。故选C。 5．篇章结构题。通读文章可知，第一段总体讲树会交流，第二、三、四段分别讲了树用化学物质、声音、“树联网”来交流，最后一段讲总结树用不同的方式交流。故选A。 Planting a tree isn’t as easy as just digging a hole and throwing the tree into it. If you want the tree to grow up, here’s what to do. ________ Do not plant trees in late spring or summer because it will be too hot and may make them die. The best time to plant a tree is fall or early spring. Choose the right tree for the area, climate, and space. Look around and find out what trees are growing well in your area. Usually, it’s better to choose one of them. Prepare the hole. Dig a hole that is 2-3 times bigger than the root ball, not just enough, so it will fit. This lets the roots grow better. Put the tree into the hole gently. Be sure the hole isn’t too deep or too shallow（浅的）. The ground level（地平面）of the plant in the pot should be the same as the ground level after you fill the hole. Water the newly planted tree. Provide 4 liters of water for every six inches（英寸）of the tree. Mulch（用腐叶覆盖）. Fill the planting hole with 1-3 inches of leaf mulch. Water it again. After the planting is finished, come back in about an hour and water it one more time. Enjoy the tree as it grows over the years with your family and friends. Get pleasure from its beauty and thank yourself for adding another tree to the world. 1．What does the writer think of planting a tree? A．Easy. B．Difficult. C．Boring. D．Tiring. 2．Which of the following can be put back into the blank? A．Find how to plant trees in the book. B．Plant trees with your friends on weekends. C．Know what kind of trees you should plant. D．Choose the right time of year for planting the tree. 3．What can we know from the passage? A．It’s good to plant trees in late spring or summer. B．The hole should be the same size as the tree’s root ball. C．We don’t need to cover the newly planted trees with leaves. D．We should water the newly planted trees again one hour later. 4．How many tips for planting trees does the writer provide? A．5. B．6. C．7. D．8. 5．Which of the following best shows the structure（结构）of the passage? A．①②③→④⑤⑥⑦⑧→⑨ B．①→②③④⑤→⑥⑦⑧⑨ C．①→②③④⑤⑥⑦⑧→⑨ D．①②③④⑤⑥→⑦⑧⑨ 【答案】1．B 2．D 3．D 4．C 5．C 【导语】本文主要介绍了种树的七个步骤。 1．细节理解题。根据“Planting a tree isn’t as easy as just digging a hole and throwing the tree into it.”可知，种树并不像挖个洞然后把树扔进去那么容易。换句话说，作者认为种树很难。故选B。 2．推理判断题。根据“Do not plant trees in late spring or summer because it will be too hot and may make them die. The best time to plant a tree is fall or early spring.”可知，不要在春末或夏末种树，因为天气太热，可能会导致树木死亡。种树的最佳时间是秋天或早春。说明这一段应是在说明要选择适当的时间去种树。故选D。 3．细节理解题。根据“After the planting is finished, come back in about an hour and water it one more time.”可知，种植完成后，大约一个小时后回来，再浇一次水。故选D。 4．细节理解题。根据“The best time to plant a tree is fall or early spring.”、“Choose the right tree for the area, climate, and space.”、“Prepare the hole.”、“Put the tree into the hole gently.”、“Water the newly planted tree.”、“Mulch（用腐叶覆盖）.”和“Water it again.”可知，作者提供了种树的7个步骤。故选C。 5．篇章结构题。文章第一段引出如何种树的话题，第二至八段介绍了种树的七个步骤，第九段总结全文，因此选项C符合题意。故选C。 Babies love chocolate and sometimes they also eat the paper around it. My cat enjoys a meal of good, thick paper, old letters, for example. She doesn’t like old newspapers very much. Of course, the best paper comes from wood. Wood comes from trees, and trees are plants. Vegetables and fruits are plants, too, and we eat a lot of them. So can we also eat wood and paper? Scientists say, “All food comes in some way from plants.” Well, is that true? Animals eat grass and grow fat. Then we eat their meat. Little fish eat little sea-plants, and then bigger fish swim along and eat them. Chickens eat bits of grass and give us eggs. So what food does not come from plants in some way? Scientists can do fantastic things with plants. They can make food just like meat and cheese. And they can make it without (没有) the help of animals. It’s very good food, too. They say, “We make our paper from wood. We can also make food from wood in the future. The next thing is not very difficult and expensive.” What is the next thing? Perhaps it is food from paper. So please keep your old books and letters. One day, they may be on your plate, if what scientists say may come true. 1．We can learn from the passage that ________. A．sometimes babies eat the paper around chocolate B．cats like to eat newspaper C．making paper from wood is very difficult D．scientists can make food like meat and cheese from paper now 2．From the passage, we can infer (推断) that ________ do not come from plants in some way. A．fish and chickens B．wood and paper C．meat and cheese D．few kinds of food 3．The writer asks us to keep our old books and letters because ________. A．there are always good stories in them B．we can make food from them so on C．we can read them at breakfast D．we can feed cats with them 4．What does the word “wood” mean in Chinese? A．塑料 B．木材 C．水泥 D．陶瓷 5．What is the best title for the passage? A．Plants Animals and Food B．Food from Plants C．Keep Your Books and Letters D．What Can We Make with Old Paper 【答案】1．A 2．D 3．B 4．B 5．B 【导语】本文主要讲述了我们生活中的食物大多数都与植物有关，而且植物可以用来做很多东西，我们的生活与植物息息相关。 1．细节理解题。根据文中“Babies love chocolate and sometimes they also eat the paper around it.”可知，婴儿喜欢巧克力，有时他们也会吃巧克力周围的纸，故选A。 2．推理判断题。根据文中“So please keep your old books and letters. One day, they may be on your plate, if what scientists say may come true.”可知，几乎没有食物与植物没关系，故选D。 3．细节理解题。根据文中“So please keep your old books and letters. One day, they may be on your plate, if what scientists say may come true.”可知，作者要求我们保留旧书和信件，因为我们可以用它们做食物，故选B。 4．词句猜测题。根据“We make our paper from wood.”可知，纸是由木材制成的，所以wood应意为“木材”，故选B。 5．最佳标题题。结合全文可知，本文主要介绍大多数食物来自于植物，我们的生活与植物息息相关，所以选项B“来自植物的食物”应为最佳标题，故选B。 进阶拓展训练7篇 A tree can go hungry when it needs food to grow, and it likes sugar very much. It’s not the same sugar in candies, but a special kind called glucose (葡萄糖) that makes trees grow. Trees make their sugar in their leaves. The sugar in the leaves then is spread into all other parts of the tree. This kind of sugar is made in a process called photosynthesis (光合作用). Photosynthesis happens when a tree uses the sunlight and chlorophyll (叶绿素) to turn CO2 (二氧化碳) and water into glucose. This glucose is the food that a tree needs when it grows. When the leaves are turning green, we know the tree is eating. But it isn’t the glucose that makes the leaves green. It is the chlorophyll. In the spring and summer, trees grow the most, because they can take in enough sunshine. Days become shorter and there is less sun when autumn comes. This makes a tree realize it’s time to get ready for winter. The leaves begin to turn red, orange and gold, because there is less sunlight and water for photosynthesis, and the green chlorophyll is about to disappear. As winter is coming, the tree has enough food it has kept when it is still warm, and passes the season in a resting state, just like bears do! The only difference between them is that bears get into a cave and lie down to rest while trees lose their leaves and stand up to fall asleep. 1．What does a tree need for food? A．Sunlight. B．Candies. C．Glucose. D．Leaves. 2．What does the underlined word “it” refer to in the second paragraph? A．Trees. B．Leaves. C．Food. D．Glucose. 3．When does a tree begin to prepare for winter? A．When there is more rain. B．When the days become longer. C．When the weather goes wetter. D．When there are fewer hours of sunshine. 4．Why do a tree’s leaves change color in the fall? A．The tree has less food to eat. B．The tree has less water. C．The tree grows faster in the autumn. D．The tree doesn’t have enough green chlorophyll. 5．What do bears and tress both do in the winter? A．Take a rest. B．Find a cave to pass the winter. C．Lie down and sleep. D．Stand up and rest. 【答案】1．C 2．A 3．D 4．D 5．A 【导语】本文介绍了树是如何生长的以及树在四季的变化。 1．细节理解题。根据“A tree can go hungry when it needs food to grow, ... It’s not the same sugar in candies, but a special kind called glucose (葡萄糖) that makes trees grow.”可知，树木需要葡萄糖来生长。故选C。 2．词句猜测题。根据“This glucose is the food that a tree needs when it grows.”可知，葡萄糖是树木生长所需的食物；因此“it”指“树木”。故选A。 3．细节理解题。根据“Days become shorter and there is less sun when autumn comes. This makes a tree realize it’s time to get ready for winter.”可知，秋天来临时，白天变短，日照时间也少了。这让一棵树意识到是时候准备过冬了。故选D。 4．细节理解题。根据“The leaves begin to turn red, orange and gold, because there is less sunlight and water for photosynthesis, and the green chlorophyll is about to disappear.”可知，叶子开始变成红色、橙色和金色，是因为光合作用的水分和阳光变少，叶绿素即将消失。故选D。 5．细节理解题。根据“As winter is coming, the tree ... passes the season in a resting state, just like bears do!”可知，冬天，树会像熊一样，进入休眠状态。故选A。 When I was a child, I liked to play on the coast of Shenzhen Bay. I used to find thin green branches. Some of those branches floated on the water, while others were in the mud on the beach, from which new branches continued to sprout (发芽). My father told me that they were the seeds of mangroves. I was surprised at their vitality and since then, I’ve been a fan of this magical plant. In middle school, I participated together with my classmates in many mangrove-related volunteer activities such as bird watching and beach cleaning. Through those activities, I have learned that the magic of mangroves lies not only in their vitality, but also in their great role in coastal ecosystem (生态系统). Mangroves are home to a great deal of marine (海洋的) life, but human activities may do harm to them. I am proud of being a native (本地人) of Shenzhen, because my city keeps putting efforts into mangroves protection. They have become the beloved “city tree” of Shenzhen. When I ride my bicycle in winter on the boardwalk of Shenzhen Bay Park, I often see many birds flying freely above the mangroves. It was informed that the first International Mangrove Center will be built in Shenzhen which means that my city will do something further to protect mangroves and do more research on the subject. Hopefully, there will be more activities open to the public, especially students, so that more teenagers like me can join in to protect mangroves. 1．What does underlined word“vitality”probably mean in the 1st paragraph? A．Life. B．Health. C．Beauty. D．Appearance. 2．What do we know about mangroves from the passage? A．They grow near the water. B．They don’t need protection now. C．They are home to many land animals. D．They may be damaged by flying birds. 3．Why is the author proud of being a native of Shenzhen? A．Because no people do harm to mangroves. B．Because there are many volunteer activities. C．Because there are a lot of mangroves in Shenzhen. D．Because Shenzhen works hard to protect mangroves. 4．What will the first International Mangrove Center bring about? A．Less research about mangroves will be done. B．Shenzhen will do more to protect mangroves. C．Fewer teenagers will come to protect mangroves. D．More people in Shenzhen will pollute mangroves. 5．What is the best title of the passage? A．Mangrove—An Endangered Plant. B．Mangrove—My Favourite Magical Plant. C．Mangrove—The ‘City Tree’ of Shenzhen. D．Mangrovc—Growing in Shenzhen Bay Park. 【答案】1．A 2．A 3．D 4．B 5．B 【导语】本文是对深圳红树林的介绍，并希望有更多关于它的活动向公众开放，特别是学生，这样就有更多青少年可以加入到保护红树林的行列中来。 1．词句猜测题。根据“Some of those branches floated on the water, while others were in the mud on the beach, from which new branches continued to sprout”可知，红树林生命力非常顽强。作者是惊讶于红树林的生命力。故选A。 2．细节理解题。根据“Some of those branches floated on the water, while others were in the mud on the beach”可知，红树林生长在水边。故选A。 3．细节理解题。根据“I am proud of being a native(本地人)of Shenzhen, because my city keeps putting efforts into mangroves protection.”可知，是因为我的城市一直在努力保护红树林。故选D。 4．细节理解题。根据“It was informed that the first International Mangrove Center will be built in Shenzhen which means that my city will do something further to protect mangroves and do more research on the subject.”可知，深圳将来会采取更多的措施保护红树林。故选B。 5．最佳标题题。根据“I was surprised at their vitality and since then, I’ve been a fan of this magical plant.”可知，本文是讲作者对红树林的热爱和保护。故选B。 There are more than 400,000 kinds of plants on Earth. Some plants are as big as tall buildings; others are as small as rice. Plants play an important part in nature because they give out oxygen—the gas that all animals need for breathing. What is a plant? Most people have no difficulty finding the differences between an animal and a plant. That is because animals can move around, but plants can’t. What makes a plant a plant? Like animals, plants are living things that are made up of lots of cells (细胞). Unlike animals, plants make their own food by photosynthesis (光合作用). Most plants have roots, stems, and leaves, and most plants reproduce by growing flowers and making seeds. All plants need energy to stay alive and grow, and they get it from sunlight instead of food. How does a plant grow? Most animals grow in a certain way, and genes (基因) control their growth. That is to say even when they are small, it’s easy to know what they will look like after they grow up. Plants are different. Their growth is controlled by genes too, but their final shapes also depend on where they live. For example, a tree can be big and round if it grows up in an open space, but much taller and thinner if it grows in the woods with other trees all around. Plants are unable to move from one environment to another, so it is important that they are able to get used to the environment. 1．Where can we most probably read the passage? A．In an advertisement.

That is because animals can move around, but plants can’t. What makes a plant a plant? Like animals, plants are living things that are made up of lots of cells (细胞). Unlike animals, plants make their own food by photosynthesis (光合作用).”可知，第二段是通过与动物对比来描述植物的。故选A。 4．细节理解题。根据“Plants are unable to move from one environment to another, so it is important that they are able to get used to the environment.”可知，植物适应环境是很重要的。故选D。 5．最佳标题题。根据通读全文可知，本文主要介绍了植物世界的特点和生长方式。故选A。 Why are the leaves on trees different colors? What makes them change color? Leaves use sunlight, water, and air to make food for the trees. This way of making food is called photosynthesis. Photosynthesis is important to animals as well as plants. Some animals eat plants. Other animals eat these animals. Summer is playtime. For the leaves of many trees, however, it’s work, work, work! The Sun is shining. The leaves are making food for the trees. The trees keep more than enough food deep inside. Leaves are green in summer because they are making food. Leaves also have orange, yellow, or brown colors inside them. During summer, those colors are covered by the green color. Many places get colder in fall with shorter days and longer nights. Trees get less sunlight, so photosynthesis slows down. Over time, leaves stop making the green chemical. The hidden orange, yellow, and brown colors grow when that happens. Once it gets cold enough and ice appears at night, the trees drop their leaves. They do this to keep themselves safe. If the leaves turn to ice while still on the trees, the trees can be hurt. Trees that drop their leaves are bare (光秃秃) in winter. They use the food they save in summer to get through the cold days and nights. Spring comes before long. Ice and snow disappear and the rains come. The Sun shines, and tiny leaves grow from branches. Once again, the leaves use sunlight, water, and air to make food. The cycle begins again. 1．What is photosynthesis according to the passage? A．It is a way of growing leaves. B．It is a way of changing colors. C．It is a way for animals to eat plants. D．It is a way to make food for plants. 2．Why are leaves green in summer? A．Because trees are making food for leaves. B．Because they are busy making food for trees. C．Because there is no other color inside leaves in summer. D．Because summer is playtime for the leaves of many trees. 3．What stops leaves from making the green chemical in fall? A．Less air in fall. B．Less time in fall. C．Less water in fall. D．Less sunlight in fall. 4．What does the underlined word “They” in Paragraph 4 refer to? A．The colors. B．The leaves. C．The trees. D．The animals. 5．What is the best title of the article? A．The colors of the tree leaves. B．The trees in different seasons. C．The importance of the sunlight. D．The changes of the four seasons. 【答案】1．D 2．B 3．D 4．C 5．A 【导语】本文介绍了树叶为什么会变颜色。 1．细节理解题。根据“Leaves use sunlight, water, and air to make food for the trees.

Plants is on Earth for millions of years and there are over 300,000 kinds of plants. Grasses and trees are common plants. Plants use photosynthesis to make their own food, and that means they use sunlight to help them produce food (sugar) and oxygen. This process (过程) never ends, so there is always food and oxygen. Plants produce most of the world’s oxygen. They are important because many animals eat plants or other animals which eat plants. Why are plants so important? Almost all living things need plants to live. Animals can’t get their food from the sunlight like plants, so they need plants (or other animals which eat plants) to get the sugar to live. They also need oxygen to breathe. Plants have something in common. First, plants make their food through photosynthesis and they don’t move from place to place. Second, plants have chlorophyll (叶绿素), and it makes leaves green and is also important to photosynthesis. Light, temperature and water can influence plant growth. It’s important to know how they influence plant growth. 1．Why does the writer write Paragraph 1? A．To enjoy different plants. B．To show the history of plants. C．To introduce some kinds of plants.

The Hundred Horse Chestnut, known as the oldest tree in the world, has lived for more than 2,000 years. It takes a very long time for trees to grow, and trees change a lot when they grow. At 1 to 3 years old, young trees learn how to protect themselves. For example, many trees grow thorns (刺) to tell animals not to go near. Most young trees have large, deep green leaves so that they can catch enough sunlight and turn it into their food and energy. When trees are 4 years old, they take in a large amount of water and nutrients to grow taller and stronger. At this time, they grow very fast and become strong enough to face challenges in life such as drought, flood and strong wind. At the age of 15, trees grow more slowly and begin to produce flowers and fruits. When the trees produce flowers for the first time, their childhood end and they become young adults (成年). When trees are 20 to 25 years old, they become real adults. The trees reach their largest sizes. Adult trees give us many things such as oxygen and natural beauty. Trees can also affect our minds. Studies show that more green leaves in our lives can reduce pressure (压力). If we give them good care, they’ll live healthily for many years. As time goes on, trees begin to grow older and older and even die. At this time, they still have their important place in nature. Enjoy every minute with the trees and take care of them! 1．Why do many trees grow thorns? A．To catch enough sunlight. B．To tell other living things to stay away. C．To turn sunlight into energy.

People have been growing Aloe Vera for thousands of years. They used it to help with health problems as long ago as 2100 BC (公元前). With long and green leaves, the plant usually grows in dry and hot places in Africa, Asia, Europe, and southern and western parts of the United States. Aloe Vera is a very hard-working plant. It can be used to help with cuts or burns. Aloe Vera also cleans the air around it. Bad air can come from the paint on the walls of some houses. Aloe Vera can make the air clean again. Aloe Vera is also a good plant to have in your room at night when you sleep. The plant can take in the air you breathe out and then give off the clean air that you breathe in. Aloe Vera is popular for its long life expectancy as well. Most Aloe plants live for around ten years indoors. However, if they are carefully cared for, they can live for over 20 years. Warm and dry air, lots of bright light, regular watering, and protection from pests and diseases will help them live longer. Growing an Aloe Vera plant at home is very easy!

Everyone should try their best to protect trees. First, try to save trees in the area where you live. Generally, large, old trees can better help improve the environment (保护环境) than small, young trees. That’s why it’s important to save as many older trees as possible. When you see a tree getting cut down, try to find out why. Sometimes trees are destroyed or diseased (被破坏或患病), so they need to be cut down. Otherwise, it’s still possible to save the tree. Planting enough new trees can also help. You should plant trees that are native to your area so that they can grow big enough easily to clean the air and water. Second, change (改变) your living habits. People cut down millions of trees each year to keep the paper industry (造纸工业) going, so using fewer paper products in your daily life can help save trees. For example, use cloth towels instead of paper towels. If you must use paper products, always buy the recycled ones. Eating less beef can also help protect trees. It may seem strange to most people, but you should know that people are cutting down rainforest trees so that people can have land to keep more cattle. 1．We can know that trees are ______ from Paragraph 1. A．beautiful B．dangerous C．important D．unusual 2．Why is it important to save as many older trees as possible? A．Because they look better than small young trees. B．Because they can help people make more money. C．Because they can do better in improving the environment. D．Because they make cleaner oxygen. 3．When you see someone cutting down a tree, you should ______. A．stop him as soon as possible B．try to find out why he is cutting down the tree C．try to help him D．make a plan to plant a new tree 4．If you want to help save trees, you should try to ______ in daily life. A．eat less meat B．use paper bags C．eat more beef D．use cloth towels 5．Which is the best title for the passage? A．Ways to save trees B．Trees in our daily lives C．Changing habit helps save trees D．Plant more trees to save the Earth Why do the leaves on trees have different colors? What makes them change color? Leaves use sunlight, water, and air to make food for the trees. This way of making food is called photosynthesis. Photosynthesis is important to animals as well as plants. Some animals eat plants. Other animals eat these animals. Summer is playtime. For the leaves of many trees, however, it’s work, work, work! The Sun is shining. The leaves are making food for the trees. The trees keep more than enough food deep inside. Leaves are green in summer because they are making food. Leaves also have orange, yellow, or brown colors inside them. During summer, those colors are covered by the green color. Many places get colder in autumn with shorter days and longer nights. Trees get less sunlight, so photosynthesis slows down. Over time, leaves stop making the green chemical (化学物质). The orange, yellow, and brown colors grow when that happens. Once it gets cold enough and ice appears at night, the trees drop their leaves. They do this to keep themselves safe. If the leaves turn to ice while still on the trees, the trees can be hurt. Trees that drop their leaves are bare (光秃秃) in winter. They use the food they save in summer to get through the cold days and nights. Spring comes before long. Ice and snow disappear and the rains come. The Sun shines, and tiny leaves grow from branches. Once again, the leaves use sunlight, water, and air to make food. The cycle begins again. 1．What is photosynthesis according to the passage? A．It is a way of growing leaves. B．It is a way of changing colors. C．It is a way to make food for plants. D．It is a way for animals to eat plants. 2．Why are leaves green in summer? A．Because trees are making food for leaves. B．Because summer is playtime for the leaves of many trees. C．Because there is no other color inside leaves in summer. D．Because they are busy making food for trees. 3．What stops leaves from making the green chemical in autumn? A．Less air in autumn. B．Less sunlight in autumn. C．Less water in autumn. D．Less time in autumn. 4．What does the underlined word “They” in Paragraph 4 refer to? A．The trees. B．The leaves. C．The colors. D．The animals. 5．What is the best title of the passage? A．The importance of the sunlight. B．The trees in different seasons. C．The colors of the tree leaves. D．The changes of the four seasons. Spring is a good time to start planning a vegetable or flower garden. Here is some fun work to do before you are ready to put your first plants in the ground. ※ Think about a theme If you have not decided what you want to plant in your garden, you can use a theme to guide you. If you want to plant vegetables, you can do a “pizza garden” that includes what you will plant. ※ Draw an outline (草图) When you or your family want to plant a new garden next spring or change the one you have now, you can start by drawing an outline for it. • Go outside and measure (测量) your garden or the area where you’d like to plant a new one. • Draw a simple outline of the garden on the paper. • Pencil in what you’d like to plant this year. ※ Prepare the space It’s important to wait to plant your garden until the last frost (霜冻) has happened in your area. Even if it’s not time to plant, you can start working on the soil (泥土). You just need to make sure it isn’t too wet from winter rains. ※ Start your plants If you want to grow some of your plants from seeds, plant the seeds in small boxes and place them in the sunlight. Once the ground is warm enough for you to plant outside, you can move them into your garden. 1．What can a theme be used for? A．Measuring your garden. B．Deciding what you plant quickly. C．Knowing more about your garden. D．Drawing an outline of your garden. 2．When should you start to plant your garden? A．After the last frost ends. B．When the winter rains come. C．Until the soil is wet enough. D．Until the weather becomes cool. 3．Which of the following is TRUE according to the text? A．Put the seeds in a dark place. B．Move your plants into warm soil. C．Buy some plants if you have no time. D．Start your garden by preparing the space. 4．What is the text mainly about? A．The reasons for drawing an outline. B．The adventures of planting a new garden. C．The ways to start a new garden. D．The importance of planning a spring garden. 5．What is the theme of the passage? A．Health. B．Nature. C．Travel. D．Culture. There are about 360 kinds of famous flowers in China. I see and plant many kinds of them. I like peonies (牡丹) best. Peony has a history of 3,000 years. Now Luoyang has the best peony garden and different kinds of peonies. My home is not far from Luoyang. Every year I come here to enjoy the peonies. Peony flowers bloom (盛开) before the Tomb-sweeping Day (清明节). Most people love peonies because they are big in flowers and rich in kinds. Do you like them? You can come and see at least (至少) seven colors of the peony flowers, such as red, pink, yellow and purple. 根据材料内容选择最佳答案。 1．How many kinds of famous flowers are there in China? A．360. B．3,000. C．10. D．4. 2．What’s the writer’s favorite flower? A．Roses. B．Peonies. C．Cactuses. D．Sun flowers. 3．How often does the writer come to Luoyang? A．Once a year. B．Twice a year. C．Three times a year. D．Four times a year. 4．When do the peony flowers bloom? A．Before the Spring Festival. B．Before the Tomb-sweeping Day. C．Before the Mid-Autumn Festival. D．Before the Tree-planting Day. 5．How many colors of the peony flowers can you see in Luoyang? A．At least 4. B．At least 7. C．At least 10. D．At least 17. ①Can trees talk? Some scientists find that trees can really “talk”! ②Some trees use chemicals (化学物质) to talk. When insects attack them, they gives out chemicals from the leaves. This is like a call for help, “I’m being attacked!” Some of these chemicals drive insects away. Others can call birds to come to kill the insects. Scientists hope to learn more about this, so that we can use it to keep insects away from crops like rice. ③More surprisingly, trees also use sound to talk. People can’t hear these sounds, but trees are making them. Some plants make noises with their roots. Some trees make noises when there is not enough water. ④Most surprisingly of all, trees have an “Internet” to give out and get information in a big forest. Scientists call it the “Wood Wide Web” (树联网). The fungi (真菌) underground help build up the “Wood Wide Web” among the roots of different trees. It is just like the Internet we use. Using the “Wood Wide Web”, trees can share information and even food with each other. However, it may also be harmful. Some trees may use it to take too much food from others, or give out chemicals to hurt other plants. Perhaps one day scientists will learn how to build a “Great Wall” to help stop these. ⑤Trees talk to each other in different ways. Now, scientists are learning more about these ways and maybe one day we will be able to “talk” with trees ourselves. 1．Trees can “talk” in different ways. How many ways does the passage show? ________ A．One. B．Two. C．Three. D．Four. 2．What does the word “attack” mean in paragraph 2?  ________ A．Hurt. B．Burn. C．Protect. D．Catch. 3．Why may trees make noise according to paragraph 3?  ________ A．They want to use chemicals. B．They need more water to keep alive. C．They would like to share information. D．They hope people to hear their sound. 4．If there is no rain for a long time, what disadvantages (坏处) may the “Wood Wide Web” bring?  ________ A．Insects may eat more leaves. B．Fungi may not be able to work. C．Some tees may take in water from others. D．Scientists may build up a wall in the forest. 5．What is the structure of the passage?  ________ A． B． C． D． Planting a tree isn’t as easy as just digging a hole and throwing the tree into it. If you want the tree to grow up, here’s what to do. ________ Do not plant trees in late spring or summer because it will be too hot and may make them die. The best time to plant a tree is fall or early spring. Choose the right tree for the area, climate, and space. Look around and find out what trees are growing well in your area. Usually, it’s better to choose one of them. Prepare the hole. Dig a hole that is 2-3 times bigger than the root ball, not just enough, so it will fit. This lets the roots grow better. Put the tree into the hole gently. Be sure the hole isn’t too deep or too shallow（浅的）. The ground level（地平面）of the plant in the pot should be the same as the ground level after you fill the hole. Water the newly planted tree. Provide 4 liters of water for every six inches（英寸）of the tree. Mulch（用腐叶覆盖）. Fill the planting hole with 1-3 inches of leaf mulch. Water it again. After the planting is finished, come back in about an hour and water it one more time. Enjoy the tree as it grows over the years with your family and friends. Get pleasure from its beauty and thank yourself for adding another tree to the world. 1．What does the writer think of planting a tree? A．Easy. B．Difficult. C．Boring. D．Tiring. 2．Which of the following can be put back into the blank? A．Find how to plant trees in the book. B．Plant trees with your friends on weekends. C．Know what kind of trees you should plant. D．Choose the right time of year for planting the tree. 3．What can we know from the passage? A．It’s good to plant trees in late spring or summer. B．The hole should be the same size as the tree’s root ball. C．We don’t need to cover the newly planted trees with leaves. D．We should water the newly planted trees again one hour later. 4．How many tips for planting trees does the writer provide? A．5. B．6. C．7. D．8. 5．Which of the following best shows the structure（结构）of the passage? A．①②③→④⑤⑥⑦⑧→⑨ B．①→②③④⑤→⑥⑦⑧⑨ C．①→②③④⑤⑥⑦⑧→⑨ D．①②③④⑤⑥→⑦⑧⑨ Babies love chocolate and sometimes they also eat the paper around it. My cat enjoys a meal of good, thick paper, old letters, for example. She doesn’t like old newspapers very much. Of course, the best paper comes from wood. Wood comes from trees, and trees are plants. Vegetables and fruits are plants, too, and we eat a lot of them. So can we also eat wood and paper? Scientists say, “All food comes in some way from plants.” Well, is that true? Animals eat grass and grow fat. Then we eat their meat. Little fish eat little sea-plants, and then bigger fish swim along and eat them. Chickens eat bits of grass and give us eggs. So what food does not come from plants in some way? Scientists can do fantastic things with plants. They can make food just like meat and cheese. And they can make it without (没有) the help of animals. It’s very good food, too. They say, “We make our paper from wood. We can also make food from wood in the future. The next thing is not very difficult and expensive.” What is the next thing? Perhaps it is food from paper. So please keep your old books and letters. One day, they may be on your plate, if what scientists say may come true. 1．We can learn from the passage that ________. A．sometimes babies eat the paper around chocolate B．cats like to eat newspaper C．making paper from wood is very difficult D．scientists can make food like meat and cheese from paper now 2．From the passage, we can infer (推断) that ________ do not come from plants in some way. A．fish and chickens B．wood and paper C．meat and cheese D．few kinds of food 3．The writer asks us to keep our old books and letters because ________. A．there are always good stories in them B．we can make food from them so on C．we can read them at breakfast D．we can feed cats with them 4．What does the word “wood” mean in Chinese? A．塑料 B．木材 C．水泥 D．陶瓷 5．What is the best title for the passage? A．Plants Animals and Food B．Food from Plants C．Keep Your Books and Letters D．What Can We Make with Old Paper 进阶拓展训练7篇 A tree can go hungry when it needs food to grow, and it likes sugar very much. It’s not the same sugar in candies, but a special kind called glucose (葡萄糖) that makes trees grow. Trees make their sugar in their leaves. The sugar in the leaves then is spread into all other parts of the tree. This kind of sugar is made in a process called photosynthesis (光合作用). Photosynthesis happens when a tree uses the sunlight and chlorophyll (叶绿素) to turn CO2 (二氧化碳) and water into glucose. This glucose is the food that a tree needs when it grows. When the leaves are turning green, we know the tree is eating. But it isn’t the glucose that makes the leaves green. It is the chlorophyll. In the spring and summer, trees grow the most, because they can take in enough sunshine. Days become shorter and there is less sun when autumn comes. This makes a tree realize it’s time to get ready for winter. The leaves begin to turn red, orange and gold, because there is less sunlight and water for photosynthesis, and the green chlorophyll is about to disappear. As winter is coming, the tree has enough food it has kept when it is still warm, and passes the season in a resting state, just like bears do! The only difference between them is that bears get into a cave and lie down to rest while trees lose their leaves and stand up to fall asleep. 1．What does a tree need for food? A．Sunlight. B．Candies. C．Glucose. D．Leaves. 2．What does the underlined word “it” refer to in the second paragraph? A．Trees. B．Leaves. C．Food. D．Glucose. 3．When does a tree begin to prepare for winter? A．When there is more rain. B．When the days become longer. C．When the weather goes wetter. D．When there are fewer hours of sunshine. 4．Why do a tree’s leaves change color in the fall? A．The tree has less food to eat. B．The tree has less water. C．The tree grows faster in the autumn. D．The tree doesn’t have enough green chlorophyll. 5．What do bears and tress both do in the winter? A．Take a rest. B．Find a cave to pass the winter. C．Lie down and sleep. D．Stand up and rest. When I was a child, I liked to play on the coast of Shenzhen Bay. I used to find thin green branches. Some of those branches floated on the water, while others were in the mud on the beach, from which new branches continued to sprout (发芽). My father told me that they were the seeds of mangroves. I was surprised at their vitality and since then, I’ve been a fan of this magical plant. In middle school, I participated together with my classmates in many mangrove-related volunteer activities such as bird watching and beach cleaning. Through those activities, I have learned that the magic of mangroves lies not only in their vitality, but also in their great role in coastal ecosystem (生态系统). Mangroves are home to a great deal of marine (海洋的) life, but human activities may do harm to them. I am proud of being a native (本地人) of Shenzhen, because my city keeps putting efforts into mangroves protection. They have become the beloved “city tree” of Shenzhen. When I ride my bicycle in winter on the boardwalk of Shenzhen Bay Park, I often see many birds flying freely above the mangroves. It was informed that the first International Mangrove Center will be built in Shenzhen which means that my city will do something further to protect mangroves and do more research on the subject. Hopefully, there will be more activities open to the public, especially students, so that more teenagers like me can join in to protect mangroves. 1．What does underlined word“vitality”probably mean in the 1st paragraph? A．Life. B．Health. C．Beauty. D．Appearance. 2．What do we know about mangroves from the passage? A．They grow near the water. B．They don’t need protection now. C．They are home to many land animals. D．They may be damaged by flying birds. 3．Why is the author proud of being a native of Shenzhen? A．Because no people do harm to mangroves. B．Because there are many volunteer activities. C．Because there are a lot of mangroves in Shenzhen. D．Because Shenzhen works hard to protect mangroves. 4．What will the first International Mangrove Center bring about? A．Less research about mangroves will be done. B．Shenzhen will do more to protect mangroves. C．Fewer teenagers will come to protect mangroves. D．More people in Shenzhen will pollute mangroves. 5．What is the best title of the passage? A．Mangrove—An Endangered Plant. B．Mangrove—My Favourite Magical Plant. C．Mangrove—The ‘City Tree’ of Shenzhen. D．Mangrovc—Growing in Shenzhen Bay Park. There are more than 400,000 kinds of plants on Earth. Some plants are as big as tall buildings; others are as small as rice. Plants play an important part in nature because they give out oxygen—the gas that all animals need for breathing. What is a plant? Most people have no difficulty finding the differences between an animal and a plant. That is because animals can move around, but plants can’t. What makes a plant a plant? Like animals, plants are living things that are made up of lots of cells (细胞). Unlike animals, plants make their own food by photosynthesis (光合作用). Most plants have roots, stems, and leaves, and most plants reproduce by growing flowers and making seeds. All plants need energy to stay alive and grow, and they get it from sunlight instead of food. How does a plant grow? Most animals grow in a certain way, and genes (基因) control their growth. That is to say even when they are small, it’s easy to know what they will look like after they grow up. Plants are different. Their growth is controlled by genes too, but their final shapes also depend on where they live. For example, a tree can be big and round if it grows up in an open space, but much taller and thinner if it grows in the woods with other trees all around. Plants are unable to move from one environment to another, so it is important that they are able to get used to the environment. 1．Where can we most probably read the passage? A．In an advertisement. B．In a storybook C．In a science magazine. D．In a poster. 2．Which of the following is NOT mentioned in Paragraph 1? A．Number of plants. B．Different sizes of plants. C．Importance of plants. D．Parts of plants. 3．How does the author describe the plants in Paragraph 2? A．By comparing. B．By giving examples. C．By giving numbers. D．By telling stories. 4．What can we know about plants from the passage? A．Flowers and seeds are the most important parts of a plant. B．Plants and animals grow in the same way. C．Only environment controls the plants’ growth. D．It’s important for the plants to get used to the environment. 5．Which can be the best title for the passage? A．The Plant World B．Parts of a Plant C．Plants and Animals D．Plants and Environment Why are the leaves on trees different colors? What makes them change color? Leaves use sunlight, water, and air to make food for the trees. This way of making food is called photosynthesis. Photosynthesis is important to animals as well as plants. Some animals eat plants. Other animals eat these animals. Summer is playtime. For the leaves of many trees, however, it’s work, work, work! The Sun is shining. The leaves are making food for the trees. The trees keep more than enough food deep inside. Leaves are green in summer because they are making food. Leaves also have orange, yellow, or brown colors inside them. During summer, those colors are covered by the green color. Many places get colder in fall with shorter days and longer nights. Trees get less sunlight, so photosynthesis slows down. Over time, leaves stop making the green chemical. The hidden orange, yellow, and brown colors grow when that happens. Once it gets cold enough and ice appears at night, the trees drop their leaves. They do this to keep themselves safe. If the leaves turn to ice while still on the trees, the trees can be hurt. Trees that drop their leaves are bare (光秃秃) in winter. They use the food they save in summer to get through the cold days and nights. Spring comes before long. Ice and snow disappear and the rains come. The Sun shines, and tiny leaves grow from branches. Once again, the leaves use sunlight, water, and air to make food. The cycle begins again. 1．What is photosynthesis according to the passage? A．It is a way of growing leaves. B．It is a way of changing colors. C．It is a way for animals to eat plants. D．It is a way to make food for plants. 2．Why are leaves green in summer? A．Because trees are making food for leaves. B．Because they are busy making food for trees. C．Because there is no other color inside leaves in summer. D．Because summer is playtime for the leaves of many trees. 3．What stops leaves from making the green chemical in fall? A．Less air in fall. B．Less time in fall. C．Less water in fall. D．Less sunlight in fall. 4．What does the underlined word “They” in Paragraph 4 refer to? A．The colors. B．The leaves. C．The trees. D．The animals. 5．What is the best title of the article? A．The colors of the tree leaves. B．The trees in different seasons. C．The importance of the sunlight. D．The changes of the four seasons. ①There is not much water in Africa.

One famous meat-eating plant is the Venus flytrap (捕蝇草). The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly touches one of the hairs, the leaf closes quickly. The fly cannot get out. In about half an hour, the leaf presses (按压) the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly. Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some places, the ground is very poor. It doesn’t have any significant things, especially nitrogen (氮). Animal meat has a lot of nitrogen, so some plants need to eat their meat to get what they need. 1．The Venus flytrap is a kind of ________.

Plants is on Earth for millions of years and there are over 300,000 kinds of plants. Grasses and trees are common plants. Plants use photosynthesis to make their own food, and that means they use sunlight to help them produce food (sugar) and oxygen. This process (过程) never ends, so there is always food and oxygen. Plants produce most of the world’s oxygen. They are important because many animals eat plants or other animals which eat plants. Why are plants so important? Almost all living things need plants to live. Animals can’t get their food from the sunlight like plants, so they need plants (or other animals which eat plants) to get the sugar to live. They also need oxygen to breathe. Plants have something in common. First, plants make their food through photosynthesis and they don’t move from place to place. Second, plants have chlorophyll (叶绿素), and it makes leaves green and is also important to photosynthesis. Light, temperature and water can influence plant growth. It’s important to know how they influence plant growth. 1．Why does the writer write Paragraph 1? A．To enjoy different plants. B．To show the history of plants. C．To introduce some kinds of plants.

The Hundred Horse Chestnut, known as the oldest tree in the world, has lived for more than 2,000 years. It takes a very long time for trees to grow, and trees change a lot when they grow. At 1 to 3 years old, young trees learn how to protect themselves. For example, many trees grow thorns (刺) to tell animals not to go near. Most young trees have large, deep green leaves so that they can catch enough sunlight and turn it into their food and energy. When trees are 4 years old, they take in a large amount of water and nutrients to grow taller and stronger. At this time, they grow very fast and become strong enough to face challenges in life such as drought, flood and strong wind. At the age of 15, trees grow more slowly and begin to produce flowers and fruits. When the trees produce flowers for the first time, their childhood end and they become young adults (成年). When trees are 20 to 25 years old, they become real adults. The trees reach their largest sizes. Adult trees give us many things such as oxygen and natural beauty. Trees can also affect our minds. Studies show that more green leaves in our lives can reduce pressure (压力). If we give them good care, they’ll live healthily for many years. As time goes on, trees begin to grow older and older and even die. At this time, they still have their important place in nature. Enjoy every minute with the trees and take care of them! 1．Why do many trees grow thorns? A．To catch enough sunlight. B．To tell other living things to stay away. C．To turn sunlight into energy.
