At first, we thought it was just a simple task, but it turned out to be far 11 than we had thought. Never before 12 we seen so many students showing interest in protecting nature. There were many young trees in the park, and each class was allowed to adopt 13 of them. Our class chose a maple tree near the lake. When we arrived, we found a sign next to it, saying that the tree 14 by volunteers 6 years ago. We learned that taking care of a tree was not only about watering it. It also meant 15 the ground around it loose and checking 16 insects were harming it. As the park manager told us, trees grow better when the soil can “breathe”. To make the tree healthier, we decided to make a weekly care plan. 17 the park was farther than our schoolyard, we didn’t mind walking 18 longer distance. We sang songs, cleaned the area, and took photos to record its growth. Not only did this activity help us understand the importance of trees, 19 it also made us feel closer to nature. 20 every citizen cares for a tree, the city will become greener and more beautiful in the future. 11．A．hard B．harder C．hardest 12．A．had B．have C．did 13．A．\ B．one C．first 14．A．planted B．was planted C．had planted 15．A．made B．to make C．making 16．A．that B．whether C．what 17．A．Although B．But C．Because 18．A．a B．an C．the 19．A．and B．or C．but 20．A．If B．As C．Though 【答案】 11．B 12．A 13．B 14．B 15．C 16．B 17．A 18．A 19．C 20．A 【导语】本文是一篇记叙文，主要讲述了学校开展在世纪公园认养树木的特殊活动，介绍了活动过程、认养树木后的养护工作，还阐述了活动带来的意义，即让学生理解树木重要性、更亲近自然，以及呼吁市民都参与能让城市更美好。 11．句意：起初，我们认为这只是一个简单的任务，但结果比我们想象的要难得多。 根据“far”以及“than”可知，此处要用比较级形式，“hard”的比较级是“harder”，“far harder”表示“难得多”，符合语境。“hard”是原级，“hardest”是最高级，均不符合此处比较的语境。 12．句意：我们以前从未见过这么多学生对保护自然感兴趣。 “Never before”表示“以前从未”，常与过去完成时连用，其结构为“had + 过去分词”。“had seen”是过去完成时结构，符合语境。“have seen”是现在完成时，“did see”是一般过去时的强调形式，均不符合“Never before”所要求的时态。 13．句意：公园里有很多小树，每个班级都被允许认养其中的一棵。 根据“each class”以及“of them”可知，这里说的是每个班级认养一棵树，“one”表示“一个”，“one of them”表示“它们中的一个”，符合语境。“\”不填不符合句子表达；“first”表示“第一”，不符合此处认养树木数量的语境。 14．句意：当我们到达时，我们在旁边发现了一个标志，上面写着这棵树是6年前由志愿者种植的。 根据“6 years ago”可知，句子要用一般过去时，且“the tree”和“plant”之间是被动关系，即树被种植，要用一般过去时的被动语态，其结构为“was/were + 过去分词”。“was planted”符合一般过去时被动语态的结构，符合语境。“planted”是一般过去时的主动形式，“had planted”是过去完成时的主动形式，均不符合树被种植的被动语境。 15．句意：这也意味着要把它周围的地面弄松，并检查是否有昆虫在伤害它。 “mean doing sth.”是固定搭配，表示“意味着做某事”，所以此处要用动名词形式“making”。“made”是过去式，“to make”是动词不定式，均不符合“mean”的固定搭配用法。 16．句意：这也意味着要把它周围的地面弄松，并检查是否有昆虫在伤害它。 根据“checking...insects were harming it”可知，这里是在检查是否有昆虫在伤害树，“whether”表示“是否”，引导宾语从句，符合语境。“that”引导宾语从句时无实际意义，“what”在宾语从句中要充当主语、宾语等成分，均不符合此处检查是否有昆虫的语境。 17．句意：虽然公园比我们的校园远，但我们不介意走更长的路。 根据“the park was farther than our schoolyard”以及“we didn’t mind walking...longer distance”可知，前后句是让步关系，“Although”表示“虽然，尽管”，引导让步状语从句，符合语境。“But”表示转折，“Because”表示原因，均不符合此处句子间的逻辑关系。 18．句意：虽然公园比我们的校园远，但我们不介意走更长的路。 “distance”是可数名词单数，且“longer”是以辅音音素开头的单词，所以要用不定冠词“a”来修饰，“a longer distance”表示“一段更长的路”。“an”用于以元音音素开头的单词前，“the”是定冠词，均不符合此处语境。 19．句意：这项活动不仅帮助我们理解了树木的重要性，而且让我们感觉更亲近自然。 “not only...but also...”是固定搭配，表示“不但……而且……”，所以此处要用“but”。“and”表示“和”，“or”表示“或者”，均不符合该固定搭配的用法。 20．句意：如果每个市民都爱护一棵树，未来城市将会变得更绿更美丽。 根据“every citizen cares for a tree”以及“the city will become greener and more beautiful in the future”可知，前一句是后一句的条件，“If”表示“如果”，引导条件状语从句，符合语境。“As”表示“当……时候；因为”，“Though”表示“虽然”，均不符合此处条件关系的语境。 C.根据短文内容，从A、B、C三个选项中选出一个语法正确的答案。 From childhood walks through Edinburgh’s Botanic Garden to my job working there, trees have always been important to me. When we 21 to collect money to save Benmore’s giant redwood trees, my work friends had an idea for a “tree huggathon” to raise funds—a perfect idea because I’ve always loved trees. I agreed 22 350 different trees in a year, hugging them whenever I felt like it in all seasons. Winter brought special maples and bright red dogwoods. Summer offered branches 23 by the sun. My way of hugging was easy: try to touch as much of the tree as possible, with arms wide open. Though my friend taking pictures sometimes found 24 hard not to laugh, I kept going. Each tree was special. Young giant redwoods gave off a sweet smell after dry weeks. A strange-looking wingnut tree looked like the talking trees in The Lord of the Rings. People walking by laughed quietly, and my family said I was silly, but it was all for a good reason. We collected more than twice the money we hoped for, 25 will help the redwoods planted in 1863. Hugging a tree shows you its 26 shape—something people could never make. While I hope to see the huge trees in California one day, hugging trees here helps me feel close to nature, makes my busy life feel 27 , and teaches me to be patient because trees live for so long. I believe that this activity is meaningful. The trees that I hugged are 28 old friends. 29 you have never tried it, I strongly recommend tree-hugging. The experience is something 30 I will always remember. 21．A．need B．needed C．are needing 22．A．hug B．hugging C．to hug 23．A．lit B．lighting C．to light 24．A．it B．that C．this 25．A．that B．what C．which 26．A．amazing B．amazed C．to amaze 27．A．slow B．slower C．slowest 28．A．to B．as C．like 29．A．If B．Before C．After 30．A．who B．what C．that 【答案】 21．B 22．C 23．A 24．A 25．C 26．A 27．B 28．C 29．A 30．C 【导语】本文讲述了作者参与“拥抱树马拉松”活动为拯救巨型红杉树筹集资金的经历，强调了这一活动对作者亲近自然、感受生活等方面的意义。 21．句意：当我们需要筹集资金来拯救本莫尔的巨型红杉树时，我的工作伙伴想出了一个“拥抱树马拉松”来筹集资金的主意——这是个绝妙的主意，因为我一直都很喜欢树。 事情发生在过去，应用一般过去时，need的过去式是needed。 22．句意：我同意在一年内拥抱350棵不同的树，无论何时我想，在所有季节都可以拥抱它们。 agree to do sth.表示“同意做某事”，是固定搭配，所以这里应用to hug。 23．句意：夏天，阳光照耀下的树枝闪闪发光。 branches和light之间是被动关系，即树枝被阳光照亮，应用过去分词作后置定语，lit是light的过去式和过去分词。 24．句意：虽然给我拍照的朋友有时发现很难不笑，但我还是继续。 find it hard to do sth.表示“发现做某事很难”，it作形式宾语，真正的宾语是后面的动词不定式，that和this不能作形式宾语。 25．句意：我们筹集到的资金是我们期望的两倍多，这将有助于1863年种植的红杉树。 这是一个非限制性定语从句，先行词是前面整个句子，关系词在从句中作主语，应用which引导。 26．句意：拥抱一棵树能让你看到它令人惊叹的形状——这是人类永远无法创造出来的。 这里修饰shape，应用形容词，amazing表示“令人惊叹的”，常用来修饰物，amazed表示“感到惊叹的”，常用来修饰人，to amaze是动词不定式形式，不能修饰名词。 27．句意：虽然我希望有一天能看到加利福尼亚的参天大树，但在这里拥抱树让我感觉亲近自然，让我忙碌的生活感觉更慢，也教会我要有耐心，因为树能活很久。 这里是将拥抱树前后的生活作比较，应用比较级，slow的比较级是slower。 28．句意：我拥抱过的树就像老朋友一样。 此处指“像老朋友”，like表示“像”。to“到”，as更强调类比，不符合语境。 29．句意：如果你从未尝试过，我强烈推荐拥抱树。 前句是后句的条件，这里表达“如果从未尝试过”，应用if引导条件状语从句；before“在……之前”，after“在……之后”不符合语境。 30．句意：这段经历是我将永远记住的事情。 这是一个定语从句，先行词是something，关系词在从句中作宾语，应用that引导。 选词填空 A.根据短文内容，从下面方框中选择适当的单词或短语填空，使短文内容完整正确。 注意：每个单词或短语只能用一次，有一个单词或短语是多余的。 A．protect    B．lose    C． hard    D．disappear    E. all the time    F. easy Today we can see that many people are cutting down the trees in the forests.

In the past, there were some ideas that plants had feelings and could act like people. But now, new studies show that plants are 1 in their own ways. Protecting (保护) themselves One way is how plants protect themselves. For example, when worms eat them, tomato plants can make their leaves taste 2 with a special juice. This can even make the worms eat each other! Corn (玉米) plants can check what worms leave behind and then use that information to 3 a bee to hunt the worms. Plant communication Plants can also talk to each other. They mainly use special air. There are small 4 on plants that look like little fish mouths under a microscope. These things let out air with information. When a plant has problems, like being eaten or hurt by the wind, it sends a “call”. Other plants close to it can get this “call” and get ready to stay safe. Plant memory Do plants have memory? One example is the “memory of winter”. Many fruit trees need to “remember” the 5 of cold days in winter to blossom in spring. They remember the cold and warm days to stop flowering too early during a warm time in winter. Now, when we look at plants in a park, we can think of them as little “strangers” (陌生人) with their own “stories” going on all around.

They might look quiet, but they are 7 “talking” to each other. Trees communicate mainly through their 8 . By linking up with other trees, they create a kind of underground network. With this underground network, trees share food and nutrients. Some trees have special roots called mycorrhizal fungi (菌根真菌). These fungi are like delivery persons—they help 9 food and nutrients from one tree to another. How cool is that! Some young trees growing in dark parts of a forest are too small to compete with taller trees for 10 , so the mother trees can provide food and care for their young ones by using this network. Trees also pass on messages through the air. For example, a giraffe is eating the leaves of a tree, then the tree can send out scent (气味) signals in the air. When other trees 11 the message, they protect themselves by making their leaves taste 12 to drive away the giraffe. So next time you’re walking in the woods, remember, the trees are not just standing there. 13 , they’re busy sending messages.

As more and more people came to live in Hong Kong, these trees were cut down and burnt. Now there is 14 forest left, though there are still some small areas covered by trees. We call these woods. Elephants, tigers and many 15 animals were living in the thick forest. When people came to live in Hong Kong, animals began to die 16 . Early farmers grew rice and 17 pigs and chickens in the valleys. They cut down the trees and burnt them. They needed 18 to keep themselves warm in winter, to cook their food and to keep away the dangerous animals. Elephants quickly disappeared because there was not enough food for them. 19 did most of the wolves and tigers. Monkeys and many other animals soon died in the same way. You might think that there are no longer any animals in Hong Kong 20 in the zoos. There are still about 36 different animals living there. One of the most interesting animals of Hong Kong is the barking deer. These are beautiful little animals with a rich brown coat and a white patch (补丁) under the tail. In Hong Kong, the barking deer has only a real enemy-men. People 21 these little animals though it is illegal. There are now not many barking deer left.

But scientists have found an amazing tree. It not only survives lightning strikes (击中), but actually grows better because of them! For years, scientists thought lightning was only bad for trees. But as they explored places like the Amazon rainforest, they started to think there could be trees that fight against lightning. It wasn’t until about 100 years ago that such“super trees” were discovered. Now, they know of a tree that uses lightning’s power to kill nearby trees and get more sunlight and nutrients (营养) for itself. In 2015, scientist Evan Gora saw a Dipteryx oleifera tree, which had been struck by strong lightning. It wasn’t badly harmed while the neighboring trees were killed. Scientists thought this tree could deal with lightning, but there was no way to be sure. Gora and his team saw more of these trees that grew well after lightning strikes. So, they did a study. They followed 93 trees struck by lightning for 2-6 years. They found that all 9 Dipteryx oleifera trees in the study survived with little harm. But 84 other trees were badly hurt, and 64% of them died within two years. These Dipteryx oleifera trees are very tall and have wide tops, making them 68% more likely to be struck by lightning than other trees. During the study, one of the Dipteryx trees was struck twice in 5 years yet continued to grow well. At present, more studies suggest that these trees attract lightning on purpose to destroy other trees and grow better. Scientists are not sure how these trees survive lightning, but they guess it may have something to do with the trees’ ability to carry electricity. They are also interested in other trees with similar characteristics. 1．What is special about the Dipteryx oleifera tree? A．It dies quickly after lightning strikes. B．It takes in nutrients directly from lightning. C．It grows better after being struck by lightning. D．It avoids lightning by staying under other trees. 2．Why do Dipteryx oleifera trees attract lightning? A．To get more water from the sky. B．To kill nearby trees for growth. C．To become shorter and stronger. D．To protect other trees around them. 3．What might scientists do next according to the text? A．Plant more Dipteryx oleifera trees. B．Study how trees attract lightning better. C．Find out where Dipteryx oleifera trees live. D．Look for more trees that can survive lightning. 4．What is the best title for the passage? A．Lightning: A Complete Enemy to All Trees B．How Trees Use Lightning to Water Themselves C．The Amazing Tree That Grows Better After Lightning D．Scientists’ Failed Studies on Amazon Rainforest 【答案】1．C 2．B 3．D 4．C 【导语】本文是一篇说明文，主要介绍了一种名为Dipteryx oleifera的神奇树木，它不仅能在雷击后存活，反而生长得更好，科学家对此进行了研究并推测其可能主动吸引闪电以清除竞争对手。 【详解】1．根据第一段“It not only survives lightning strikes but actually grows better because of them!”可知，这种树被闪电击中后不仅存活，反而生长得更好。 2．根据第二段“Now, they know of a tree that uses lightning’s power to kill nearby trees and get more sunlight and nutrients for itself.”以及最后一段“attract lightning on purpose to destroy other trees and grow better”可知，这种树吸引闪电是为了杀死附近的树木，从而获取更多阳光和营养以促进自身生长。 3．根据最后一段“They are also interested in other trees with similar characteristics.”可知，科学家对其他具有类似特征的树木也感兴趣，因此推测他们接下来可能会寻找更多能存活于闪电中的树木。 4．通读全文可知，文章主要围绕一种被闪电击中后反而生长得更好的神奇树木展开介绍，讲述了其特性及科学家的研究。选项C“雷击后生长得更好的神奇树木”最能概括文章主旨。 (B) Trees may seem quiet and still, but they have their own “senses” to survive in nature. Just like humans, they can feel, respond to and even “communicate” with the world around them. These special abilities help trees live for many years, even in difficult environments. Unlike humans, trees don’t have eyes, ears or hands, but their “senses” are enough to keep them safe and healthy. Trees have a strong sense of touch. When a caterpillar (毛毛虫) eats their leaves, they can feel the small bites and release a special smell to drive the caterpillar away. Sometimes, this smell can also attract other insects that eat caterpillars, helping trees get more protection. They can also sense changes in water. If there is little water in the soil, their roots will grow deeper to find more water, and their leaves will close a little to save water. Besides touch, trees can “hear” and “smell”. Some trees can sense the sound of wind and adjust their branches to avoid being broken. They can also smell harmful chemicals in the air and protect themselves by closing their leaf pores (气孔). When one tree is in danger, it sends out a chemical signal to warn other trees nearby, so they can get ready to protect themselves. In fact, trees are more amazing than we think. Their “senses” are not the same as ours, but they are very useful for their survival. By understanding tree senses, we can learn to protect them better and live in harmony with nature. Trees are important parts of our world, and their special abilities make our planet more beautiful. 5．What will trees do when a caterpillar eats their leaves? A．They will release a special smell. B．They will stop growing. C．They will break their leaves together. D．They will change their color. 6．How do trees find more water when there is little water in the soil? A．Their leaves will become smaller. B．Their roots will grow deeper. C．Their branches will grow longer. D．They will release a signal. 7．What is the author’s attitude towards trees? A．Worried and sad. B．Bored and uninterested. C．Surprised and admiring. D．Respectful and critical. 8．What’s the main idea of the passage? A．How trees grow fast. B．Trees can communicate with humans. C．How to protect trees. D．Trees have their own senses to survive. 【答案】5．A 6．B 7．C 8．D 【导语】本文主要介绍了树木的触觉、听觉、嗅觉等感官如何帮助其生存。 【详解】5．根据文章第二段第二句“When a caterpillar eats their leaves, they can feel the small bites and release a special smell to drive the caterpillar away.”可知，当毛毛虫吃叶子时，树木会释放一种特殊的气味。 6．根据文章第二段最后一句“If there is little water in the soil, their roots will grow deeper to find more water...”可知，当土壤中水很少时，树根会扎得更深去寻找水源。 7．根据文章第四段“In fact, trees are more amazing than we think.”以及“Trees are important parts of our world, and their special abilities make our planet more beautiful.”可知，作者认为树木比想象中更神奇，且让星球更美丽，体现了惊讶和赞赏的态度。 8．文章首句“Trees may seem quiet and still, but they have their own ‘senses’ to survive in nature.”点明主题，后续段落分别介绍了树木的触觉、听觉、嗅觉等感官如何帮助其生存，最后总结其重要性。因此文章主旨是树木拥有自己的感官来生存。 (C) ①Plants need to eat just like animals. However, animals can move around, so it seems easy for them to find food. But plants can’t, so does this mean it’s difficult for them to find food? The answer is “No!” because plants also have their own ways to get their “food”. ②One of the most common ways plants eat is through photosynthesis. How does this happen? Plants use sunlight, water and CO2 (二氧化碳) to make glucose. It is a kind of sugar that plants use for energy. Chlorophyll (叶绿素) can catch sunlight and turn it into energy. Trees are an example of photosynthetic plants. They can take in (吸入) CO2 from the air and give off O2 (氧气). ③Another way is through their roots. Roots take in water and other things from the soil. Then, the roots send them to the other parts of the plant. This process (过程) is important for plants to grow. For example, some plants can live in dry places. They use their roots to take in water from the soil and they have thick leaves to keep the water. ④Carnivorous (食肉的) plants are also an example of how plants get food. Some plants eat insects and other small animals. These plants have special leaves. They look like cups with sweet juice in them. Once the insects fly in, they can’t climb out. Then, the plants “eat” them. ⑤In fact, plants have many clever and special ways to get their food. Each way helps them to live and grow well. Nature is really full of interesting things for us to find out. 9．Which picture best shows how photosynthesis works? A．B．C． D． 10．What does the underlined word “them” refer to (指代)? A．Sunlight, water and CO2. B．Leaves and roots. C．Water and other things. D．Energy and water. 11．What is the right structure (结构) of this passage? A． B． C． D． 12．What is the main topic (话题) of the passage? A．What special food animals eat. B．Different Kinds of plants. C．The magic of photosynthesis. D．How plants get their food. 【答案】9．D 10．C 11．B 12．D 【导语】本文是一篇说明文，主要讲述了植物获取食物的三种方式：光合作用、根系吸收和食肉植物的特殊捕食，最后总结植物获取食物的方式多样且有趣。 【详解】9．第二段指出光合作用的过程：“Plants use sunlight, water and CO₂ to make glucose. Chlorophyll can catch sunlight and turn it into energy. Trees... take in CO₂ from the air and give off O₂”，选项D的图示正确展示了阳光、水、CO₂作为原料，生成葡萄糖和O₂的过程。 10．第三段说明根系的作用：“Roots take in water and other things from the soil. Then, the roots send them to the other parts of the plant”，此处“them”指代前文的“water and other things”。 11．文章结构为：第1段总述植物有获取食物的方式（总）；第2-4段分别介绍光合作用、根系吸收、食肉植物（分）；第5段总结植物获取食物的方式多样（总），对应选项B的结构图示。 12．文章主要围绕“植物如何获取食物”展开，第1段提出问题，第2-4段介绍三种方式，第5段总结，因此主题是“How plants get their food”。 第 1 页 共 1 页 学科网（北京）股份有限公司 $ Unit 3 Trees单元话题阅读套餐练 选材聚焦本单元话题，语篇以不同题型呈现，兼顾多种文本体裁，难度适中。 语法选择 A.根据短文内容，从A、B、C三个选项中选出一个语法正确的答案。 The Scent of Pagoda Tree (槐树) Flowers Every summer, the sweet smell of pagoda tree flowers fills my grandma’s village, which lies in the north of Anhui.

At first, we thought it was just a simple task, but it turned out to be far 11 than we had thought. Never before 12 we seen so many students showing interest in protecting nature. There were many young trees in the park, and each class was allowed to adopt 13 of them. Our class chose a maple tree near the lake. When we arrived, we found a sign next to it, saying that the tree 14 by volunteers 6 years ago. We learned that taking care of a tree was not only about watering it. It also meant 15 the ground around it loose and checking 16 insects were harming it. As the park manager told us, trees grow better when the soil can “breathe”. To make the tree healthier, we decided to make a weekly care plan. 17 the park was farther than our schoolyard, we didn’t mind walking 18 longer distance. We sang songs, cleaned the area, and took photos to record its growth. Not only did this activity help us understand the importance of trees, 19 it also made us feel closer to nature. 20 every citizen cares for a tree, the city will become greener and more beautiful in the future. 11．A．hard B．harder C．hardest 12．A．had B．have C．did 13．A．\ B．one C．first 14．A．planted B．was planted C．had planted 15．A．made B．to make C．making 16．A．that B．whether C．what 17．A．Although B．But C．Because 18．A．a B．an C．the 19．A．and B．or C．but 20．A．If B．As C．Though C.根据短文内容，从A、B、C三个选项中选出一个语法正确的答案。 From childhood walks through Edinburgh’s Botanic Garden to my job working there, trees have always been important to me. When we 21 to collect money to save Benmore’s giant redwood trees, my work friends had an idea for a “tree huggathon” to raise funds—a perfect idea because I’ve always loved trees. I agreed 22 350 different trees in a year, hugging them whenever I felt like it in all seasons. Winter brought special maples and bright red dogwoods. Summer offered branches 23 by the sun. My way of hugging was easy: try to touch as much of the tree as possible, with arms wide open. Though my friend taking pictures sometimes found 24 hard not to laugh, I kept going. Each tree was special. Young giant redwoods gave off a sweet smell after dry weeks. A strange-looking wingnut tree looked like the talking trees in The Lord of the Rings. People walking by laughed quietly, and my family said I was silly, but it was all for a good reason. We collected more than twice the money we hoped for, 25 will help the redwoods planted in 1863. Hugging a tree shows you its 26 shape—something people could never make. While I hope to see the huge trees in California one day, hugging trees here helps me feel close to nature, makes my busy life feel 27 , and teaches me to be patient because trees live for so long. I believe that this activity is meaningful. The trees that I hugged are 28 old friends. 29 you have never tried it, I strongly recommend tree-hugging.

A lot of rich land has become deserts. If we read newspapers, we’ll learn that the forests on the Earth are getting smaller and smaller 1 . We are cutting down large numbers of trees because we need wood and farmland. Some scientists say that there will not be any great forests in 20 or 30 years. What will happen if the forests 2 ? A lot of plants will die and the animals will 3 their homes. In many places the new farmland will soon look like the old deserts. Crops will not grow there.

These forests are full of 6 . When big waves come, seawater floods the trees. Fish can live there. Higher up, birds, snakes and monkeys live in the branches of the trees. But that’s not all. “Mangroves are important for local people, too.” says Camille. The forests take the 7 out of waves. This helps protect villages from flooding. However, these amazing forests are disappearing. The Philippines has lost more than half of its mangroves since the 1920s. People 8 these areas for useless land and cut down the trees. They cleared space for fish farms. But many of those man-made ponds were not used later. Why not make use of them to bring back the mangroves? Camille soon began to take action. In 2020, she set up a group called Oceanus Conservation. They started to plant mangrove trees in the ponds and brought back native crabs, shrimp and fish. Soon, the forest area 9 in size and turned back into healthy mangrove forests. The project created jobs for local people. What’s more, Camille has written books about saving mangroves.

These days, lots of young people in China are hugging trees to reduce (减少) their stress. It sounds 16 but there’s actually science behind it. It’s called the “biophilia hypothesis (亲生命假说)”. A scientist said humans naturally like spending time with other 17 things in nature. Loving nature is part of our DNA．This 18 why people prefer exploring (探索) nature and green spaces 19 staying in cities in their holidays. It’s also why people love cute pets. Although hugging trees is good for us, we need to remember we shouldn’t hurt nature while doing it. Trees are home to many small creatures (生物) that we can’t even see. 20 when you hug a tree, please be gentle just like hugging a friend!

In the past, there were some ideas that plants had feelings and could act like people. But now, new studies show that plants are 1 in their own ways. Protecting (保护) themselves One way is how plants protect themselves. For example, when worms eat them, tomato plants can make their leaves taste 2 with a special juice. This can even make the worms eat each other! Corn (玉米) plants can check what worms leave behind and then use that information to 3 a bee to hunt the worms. Plant communication Plants can also talk to each other. They mainly use special air. There are small 4 on plants that look like little fish mouths under a microscope. These things let out air with information. When a plant has problems, like being eaten or hurt by the wind, it sends a “call”. Other plants close to it can get this “call” and get ready to stay safe. Plant memory Do plants have memory? One example is the “memory of winter”. Many fruit trees need to “remember” the 5 of cold days in winter to blossom in spring. They remember the cold and warm days to stop flowering too early during a warm time in winter. Now, when we look at plants in a park, we can think of them as little “strangers” (陌生人) with their own “stories” going on all around. We don’t know if they feel pain (疼痛), but they 6 touch or respond to being eaten, even though they don’t feel pain like we do. 1．A．dangerous B．strange C．important D．unusual 2．A．ill B．bad C．badly D．delicious 3．A．call B．invite C．attract D．send 4．A．treetops B．spots C．openings D．marks 5．A．number B．days C．time D．length 6．A．avoid B．ignore C．dislike D．sense (B) Imagine you’re in a forest, and you see trees standing tall and strong. They might look quiet, but they are 7 “talking” to each other. Trees communicate mainly through their 8 . By linking up with other trees, they create a kind of underground network. With this underground network, trees share food and nutrients. Some trees have special roots called mycorrhizal fungi (菌根真菌). These fungi are like delivery persons—they help 9 food and nutrients from one tree to another. How cool is that! Some young trees growing in dark parts of a forest are too small to compete with taller trees for 10 , so the mother trees can provide food and care for their young ones by using this network. Trees also pass on messages through the air. For example, a giraffe is eating the leaves of a tree, then the tree can send out scent (气味) signals in the air. When other trees 11 the message, they protect themselves by making their leaves taste 12 to drive away the giraffe. So next time you’re walking in the woods, remember, the trees are not just standing there. 13 , they’re busy sending messages.

As more and more people came to live in Hong Kong, these trees were cut down and burnt. Now there is 14 forest left, though there are still some small areas covered by trees. We call these woods. Elephants, tigers and many 15 animals were living in the thick forest. When people came to live in Hong Kong, animals began to die 16 . Early farmers grew rice and 17 pigs and chickens in the valleys. They cut down the trees and burnt them. They needed 18 to keep themselves warm in winter, to cook their food and to keep away the dangerous animals. Elephants quickly disappeared because there was not enough food for them. 19 did most of the wolves and tigers. Monkeys and many other animals soon died in the same way. You might think that there are no longer any animals in Hong Kong 20 in the zoos. There are still about 36 different animals living there. One of the most interesting animals of Hong Kong is the barking deer. These are beautiful little animals with a rich brown coat and a white patch (补丁) under the tail. In Hong Kong, the barking deer has only a real enemy-men. People 21 these little animals though it is illegal. There are now not many barking deer left. So, it is important for people to protect wild animals. 14．A．many B．a few C．a little D．no 15．A．other B．others C．the other D．another 16．A．away B．off C．of D．out 17．A．grew B．made C．got D．kept 18．A．fire B．hotness C．heat D．stoves 19．A．So B．Such C．As D．Nor 20．A．besides B．except C．and D．or 21．A．raise B．hunt C．keep D．feed 阅读理解 Reading comprehension (A) Lightning usually destroys (破坏) trees it hits. But scientists have found an amazing tree. It not only survives lightning strikes (击中), but actually grows better because of them! For years, scientists thought lightning was only bad for trees. But as they explored places like the Amazon rainforest, they started to think there could be trees that fight against lightning. It wasn’t until about 100 years ago that such“super trees” were discovered. Now, they know of a tree that uses lightning’s power to kill nearby trees and get more sunlight and nutrients (营养) for itself. In 2015, scientist Evan Gora saw a Dipteryx oleifera tree, which had been struck by strong lightning. It wasn’t badly harmed while the neighboring trees were killed. Scientists thought this tree could deal with lightning, but there was no way to be sure. Gora and his team saw more of these trees that grew well after lightning strikes. So, they did a study. They followed 93 trees struck by lightning for 2-6 years. They found that all 9 Dipteryx oleifera trees in the study survived with little harm. But 84 other trees were badly hurt, and 64% of them died within two years. These Dipteryx oleifera trees are very tall and have wide tops, making them 68% more likely to be struck by lightning than other trees. During the study, one of the Dipteryx trees was struck twice in 5 years yet continued to grow well. At present, more studies suggest that these trees attract lightning on purpose to destroy other trees and grow better. Scientists are not sure how these trees survive lightning, but they guess it may have something to do with the trees’ ability to carry electricity. They are also interested in other trees with similar characteristics. 1．What is special about the Dipteryx oleifera tree? A．It dies quickly after lightning strikes. B．It takes in nutrients directly from lightning. C．It grows better after being struck by lightning. D．It avoids lightning by staying under other trees. 2．Why do Dipteryx oleifera trees attract lightning? A．To get more water from the sky. B．To kill nearby trees for growth. C．To become shorter and stronger. D．To protect other trees around them. 3．What might scientists do next according to the text? A．Plant more Dipteryx oleifera trees. B．Study how trees attract lightning better. C．Find out where Dipteryx oleifera trees live. D．Look for more trees that can survive lightning. 4．What is the best title for the passage? A．Lightning: A Complete Enemy to All Trees B．How Trees Use Lightning to Water Themselves C．The Amazing Tree That Grows Better After Lightning D．Scientists’ Failed Studies on Amazon Rainforest (B) Trees may seem quiet and still, but they have their own “senses” to survive in nature. Just like humans, they can feel, respond to and even “communicate” with the world around them. These special abilities help trees live for many years, even in difficult environments. Unlike humans, trees don’t have eyes, ears or hands, but their “senses” are enough to keep them safe and healthy. Trees have a strong sense of touch. When a caterpillar (毛毛虫) eats their leaves, they can feel the small bites and release a special smell to drive the caterpillar away. Sometimes, this smell can also attract other insects that eat caterpillars, helping trees get more protection. They can also sense changes in water. If there is little water in the soil, their roots will grow deeper to find more water, and their leaves will close a little to save water. Besides touch, trees can “hear” and “smell”. Some trees can sense the sound of wind and adjust their branches to avoid being broken. They can also smell harmful chemicals in the air and protect themselves by closing their leaf pores (气孔). When one tree is in danger, it sends out a chemical signal to warn other trees nearby, so they can get ready to protect themselves. In fact, trees are more amazing than we think. Their “senses” are not the same as ours, but they are very useful for their survival. By understanding tree senses, we can learn to protect them better and live in harmony with nature. Trees are important parts of our world, and their special abilities make our planet more beautiful. 5．What will trees do when a caterpillar eats their leaves? A．They will release a special smell. B．They will stop growing. C．They will break their leaves together. D．They will change their color. 6．How do trees find more water when there is little water in the soil? A．Their leaves will become smaller. B．Their roots will grow deeper. C．Their branches will grow longer. D．They will release a signal. 7．What is the author’s attitude towards trees? A．Worried and sad. B．Bored and uninterested. C．Surprised and admiring. D．Respectful and critical. 8．What’s the main idea of the passage? A．How trees grow fast. B．Trees can communicate with humans. C．How to protect trees. D．Trees have their own senses to survive. (C) ①Plants need to eat just like animals. However, animals can move around, so it seems easy for them to find food. But plants can’t, so does this mean it’s difficult for them to find food? The answer is “No!” because plants also have their own ways to get their “food”. ②One of the most common ways plants eat is through photosynthesis. How does this happen? Plants use sunlight, water and CO2 (二氧化碳) to make glucose. It is a kind of sugar that plants use for energy. Chlorophyll (叶绿素) can catch sunlight and turn it into energy. Trees are an example of photosynthetic plants. They can take in (吸入) CO2 from the air and give off O2 (氧气). ③Another way is through their roots. Roots take in water and other things from the soil. Then, the roots send them to the other parts of the plant. This process (过程) is important for plants to grow. For example, some plants can live in dry places. They use their roots to take in water from the soil and they have thick leaves to keep the water. ④Carnivorous (食肉的) plants are also an example of how plants get food. Some plants eat insects and other small animals. These plants have special leaves. They look like cups with sweet juice in them. Once the insects fly in, they can’t climb out. Then, the plants “eat” them. ⑤In fact, plants have many clever and special ways to get their food. Each way helps them to live and grow well. Nature is really full of interesting things for us to find out. 9．Which picture best shows how photosynthesis works? A．B．C． D． 10．What does the underlined word “them” refer to (指代)?
