Their fur is see-through and their hairs reflect (反射) all of the light around them, making their fur look white. Polar bears are at the top of their food chain (食物链) in the Arctic. Do you know?· Polar bears live on the land. · Polar bears live for 20—30 years. · Polar bears have thick fat to keep themselves warm. · Polar bears also have large feet to help pull themselves through the water. 16．What is the text about?

A．Polar bears have white fur all over the body. B．Polar bears have big heads and short tails. C．Polar bears can keep themselves warm. D．Polar lives in the sea. B Birch (桦树) trees are easy to see because they look special. They have thin, white or silver bark (树皮). You can sometimes take off small pieces of this bark easily. Their leaves are small. In spring, new leaves with colour like other common trees come out. In autumn, the leaves turn bright yellow and they’re like little suns on the tree! Birch trees grow in many places, such as forests and near roads. They like cold weather. Birds make homes in their parts that grow out from the body. Small animals eat their tiny seeds (种子). People use birch trees to make many things. Long ago, people made boats from their bark. Today, we use their wood to make tables, chairs and paper. Some people even drink the sap (树汁) from the tree in March and April—it is sweet and fresh. Birch trees are not very tall, but they are strong. They can live for about 40 to 50 years. Next time, if you go outside and see a birch tree, you will know it by its white outer layer and pretty leaves! 19．What colour may the leaves of birch trees be in spring? A．White. B．Silver. C．Green. D．Yellow. 20．Where may we find birch trees much more easily? A．In Hainan Province. B．In Zhejiang Province. C．In Fujian Province. D．In Heilongjiang Province. 21．When can we drink birch sap? A．In spring. B．In summer. C．In autumn. D．In winter. 22．Which of the following can we use to describe birch trees? A．Short-lived. B．Useful. C．Tall. D．Strange. C Every living thing needs to create more members of its group. Plants have to spread seeds (传播种子) to other areas. And they have developed all kinds of ways to do this. The simplest way is gravity (重力) . Many seeds are inside of fruit. When a piece of fruit gets too heavy, it falls from a tree to the ground. Sometimes animals will pick up the fruit and drop it in another area. That helps move the seeds even farther away. Apples spread their seeds this way. Other plants use the wind to spread their seeds. Dandelions (蒲公英) are a good example of this. Dandelion seeds are so light that when the wind blows, it carries dandelion seeds to new places. Some animals help plants spread their seeds. The animal eats the seeds. While the seed is in an animal’s body, it stays safe. When the seed leaves the animal, it’s in a new place. Ants also help spread seeds. Some seeds have a special smell that attracts ants. Then the ants bring the seed back to their home. They only eat part of the seed. The rest of the seed can start growing. 23．Apples spread their seeds by using ________. A．ants B．gravity C．smells D．the wind 24．What can we know about dandelions’ seeds? A．They have a special smell for ants. B．They can swim in water to new places. C．They only grow after animals eat them. D．They travel with the wind because they are light. 25．What does the underlined word “attracts” in the last paragraph mean in Chinese? A．伤害 B．隐藏 C．吸引 D．改变 26．In which part of a newspaper can we read the passage? A．Nature. B．Food. C．Music. D．Sports. D Animals have the ability to make people understand them, especially when they are in serious danger and hope to get help from man. And they often go together to help one another. One day, I visited my friend Jack on a sheep farm in North America. Suddenly one sheep came to cry in front of us. She made the most painful (痛苦的) cries. Jack said, “Something must be wrong. Come on, Mike. Let’s follow her.” Together we followed the sheep back to her farm. She rushed forward and kept on looking back to see if we were coming. She finally took us to an old well (井), and we heard the sad voice of her young baby. We found it had fallen into the well. As the well had no water and was only six feet deep, we took a ladder (梯子) and climbed down. After a few minutes, we pulled the baby sheep out of the well. The mother sheep was close to her baby. She made soft sounds and moved her tail from side to side. Sometimes, she came close to us and smelled our hands. It seemed like she was trying to say “thanks”. She came to tell us her difficulty and got help. How amazing! 27．Why did the writer go to the sheep farm? A．To buy sheep. B．To visit his friend. C．To feed sheep. D．To help his friend. 28．How did the men get the baby sheep out of the well? A．They used a ladder to climb down and pull it out. B．They threw a rope and pulled it up.

Recently, many people have shared their experience of hugging trees online, and they turned to trees to help with their stress. I wrapped my arms around it and rested my face on the trunk. I closed my eyes, took a few deep breaths and felt really calm during that moment. Hugging a tree is a different experience from hugging a person or an animal. Although it sounds strange, there is a science behind the act of tree-hugging. It can be explained by the “biophilia hypothesis” (亲生命假说). A US scientist Edward Wilson pointed it out in 1984. Humans’ love for nature is “in our DNA”. This idea helps to explain why people like natural, green views better than city views. Besides, spending time with trees can reduce your stress hormones (压力荷尔蒙) and make you feel relaxed. These oils protect trees from illnesses and germs. They are also good for human health, because they can make your immune system (免疫系统) stronger. Also, hugging a tree lets you take a close look at it. Hugging trees gives you a deeper connection (联系) to nature. You begin to enjoy nature more. A．In addition, trees give off some special oils. B．Because of this, you will want to help the environment. C．You can smell it, touch it and listen to the sound of its leaves. D．He said that humans are born to love being around other living things. E．A month ago, I hugged an orange tree in a nearby park for the first time. 31． 32． 33． 34． 35．Do you want to hug the trees? Why or why not?

They 51 the ecosystem of our planet. 52 , the number of bees 53 dropping, and scientists are 54 . Bees need our help and there is a lot that people can do. Think about what you can do 55 one of the most amazing animals on earth. B:阅读下面短文，根据括号内所给汉语注释写出单词的正确形式(每空一词)。 At the zoo, it is not difficult for us to see a panda because their black-and-white fur stands out against the green bamboo. But wait! In the wild, can a tiger see pandas as 56 (容易) as we can? Will pandas be quickly eaten in the wild? A study 57 (展示) their black-and-white color helped them hide in the wild two years ago. “If we want to 58 (理解) animal colors, we need to look at where they live.” Tim Caro from 59 (大学) of Bristol said in a report. According to Caro, wild pandas live in 60 (山) in Southwest China. There are shady places and snowy 61 (地区). Panda’s white faces and bellies help them hide in the snow. Their black arms and legs help them hide in the shade. Their colors make them 62 (优秀) in hiding in the wild. Pandas eat bamboo. They can never store 63 (足够的) fat to go through winter. So they go out to look for food all year around. The combination of black and white can fit different environments. It also breaks up the panda’s shape. This makes it even 64 (困难) for other animals to see them. Some 65 (科学家) also found that the colors on their other parts have different uses. Black ears: They work as a warning signal for predators. Black eyes: They help pandas recognize each other. 第三节 语法填空(共10小题，每小题1分，满分10分) In daily life, people, animals and plants are all connected. Bees are one of the best examples of this 66 (connect). In warm weather, we see bees fly among the 67 (flower). They carry pollen from one flower to another. This action 68 (help) plants grow well. Actually, about 80 per cent of the plants in the world can’t grow 69 their work. For this reason, many scientists believe that bees are the 70 (important) animals on this planet. There are many interesting things about bees. One thing is that they work hard together to make their homes. They create honeycombs 71 (store) honey. Another thing is that a bee can tell the others where 72 how far away the food is by dancing. Bees play 73 important part in the ecosystem of our planet. Now scientists are worried because the number of bees is 74 (drop). We should do something useful to protect 75 (they). For example, we can plant more trees because trees can give bees food and they are home to bees. 第四部分 写作 (共一节，满分20分) 76．请以Amazing Animals I Know为题，根据以下提示介绍一种你了解的神奇动物。 1. 过去你对这种动物的认识; 2. 现在你对它的新了解(特征、习性等); 3. 谈谈你的感受与想法。 词数：100词左右。 提示词：used to, amazing, habitat, adapt to 注意: 1. 表达中必须包含所给要点并进行适当发挥; 2. 词数100词左右; 3. 文中不得出现真实的姓名、校名和地名等信息。 Amazing Animals I Know __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 试卷第1页，共3页 试卷第1页，共3页 学科网（北京）股份有限公司 参考答案 题号 1 2 3 4 5 6 7 8 9 10 答案 B C C C A A B C B C 题号 11 12 13 14 15 16 17 18 19 20 答案 C B C B A B D C C D 题号 21 22 23 24 25 26 27 28 29 30 答案 A B B D C A B A C C 题号 36 37 38 39 40 41 42 43 44 45 答案 C D B A C D D A B C 题号 46 47 48 49 50 答案 B A A D B 1．B 【原文】W: Jack, I know Tom and David are your good friends.

Apples spread their seeds this way.”，此处this way指代依靠重力传播，可知苹果依靠重力传播种子。 24．第三段“Dandelion seeds are so light that when the wind blows, it carries dandelion seeds to new places.”表明蒲公英种子很轻，风会把种子带到新地方。 25．最后一段“Some seeds have a special smell that attracts ants. Then the ants bring the seed back to their home.”表明种子特殊气味引来蚂蚁搬运，attracts含义为“吸引”。 26．全文围绕植物、种子、自然生物知识展开，属于自然板块。 27．B 28．A 29．C 30．C 【导语】本文是一篇记叙文，讲述了作者在朋友Jack的农场里，一只母羊通过叫声引导他们去救掉入井里的小羊的故事，展现了动物表达求助和感恩的能力。 【详解】27．文章第二段指出“I visited my friend Jack on a sheep farm in North America.”，说明作者去农场是为了拜访朋友。 28．文章第三段指出“we took a ladder and climbed down. After a few minutes, we pulled the baby sheep out of the well.”，说明他们用梯子爬下去把小羊拉了出来。 29．文章第三段描述母羊靠近小羊并发出轻柔声音、摇尾巴、靠近作者并嗅他们的手，这些行为像是在表达感谢。由此推断，母羊感到感激和高兴。 30．文章第一段指出“Animals have the ability to make people understand them”，随后通过母羊求助的故事印证了这一观点。由此推断，动物能让人理解它们。 31．E 32．D 33．A 34．C 35．Yes, I do. Because hugging trees can help me feel relaxed and closer to nature. 【导语】本文是一篇说明文，主要讲述了拥抱树木的经历、背后的科学原理“亲生命假说”以及拥抱树木对身心健康的好处。 【详解】31．后文描述抱树的动作、感受，选项E“A month ago, I hugged an orange tree in a nearby park for the first time.”讲述第一次拥抱橘子树，与后文动作衔接。 32．前文提到科学家提出亲生命假说，选项D“He said that humans are born to love being around other living things.”中“He”指代Wilson，且内容关于人类天生喜爱生物，符合语境。 33．后文提到“These oils protect trees from illnesses and germs.”引出“oils”这一概念，选项A“In addition, trees give off some special oils.”明确提到树木释放特殊油脂，逻辑呼应。 34．前一句说近距离观察树木，选项C“You can smell it, touch it and listen to the sound of its leaves.”提到闻、触、听，符合近距离观察的描述。 35．本题为开放性问题，答案不唯一，根据自身实际，结合文本内容，合理作答即可。 36．C 37．D 38．B 39．A 40．C 41．D 42．D 43．A 44．B 45．C 46．B 47．A 48．A 49．D 50．B 【导语】本文以丹顶鹤的口吻介绍其特征、习性，并讲述因人类活动导致生存困难，呼吁人类保护。 【详解】36．句意：我们的头顶上有红色的冠。 丹顶鹤的红冠生长在头顶，固定搭配on top of，应选top“顶部”。middle“中间”、bottom“底部”、under“在……下方”均不符合位置逻辑。 37．句意：你可能以为这些冠是我们的羽毛。 前文提到red caps红色冠顶，本空指代丹顶鹤的红冠，应选caps“冠”。heads“头部”、wings“翅膀”、crowns不符合前文用词，逻辑不符。 38．句意：我们是世界上体型最大的鸟类之一，我们是最重的。 后文介绍丹顶鹤体重可达11公斤，围绕体重展开，应选heaviest“最重的”。strongest“最强壮的”、best“最好的”、oldest“最古老的”均与体重语境不符。 39．句意：一只丹顶鹤长大后体重可达11公斤。 本句描述丹顶鹤成年后的体重，应选grows up“长大”。passes by“路过”、plays around“玩耍”、gets together“聚集”均不符合句意。 40．句意：我认为我们是所有鸟类中最美的舞者。 前文提到丹顶鹤擅长跳舞，对应身份为舞者，应选dancers“舞者”。actors“演员”、painters“画家”、writers“作家”均与跳舞无关。 41．句意：我们的歌声响亮又优美。 本空修饰动词sing，需用副词，应选beautifully“优美地”。beautiful、lovely为形容词，beauty为名词，均无法修饰动词，用法不符。 42．句意：我们也擅长飞行。

后文说明丹顶鹤濒临灭绝、生存空间减少，存在转折困境，应选harder“更艰难的”。easier“更容易的”、happier“更快乐的”、clearer“更清晰的”均与转折逻辑相反。 47．句意：人类不断侵占我们的栖息地，为了建造农场和房屋。 固定搭配keep doing sth.表示“持续做某事”，后接动名词，应选taking。takes、took为谓语动词，to take为不定式，均不符合语法规则。 48．句意：人类不断侵占我们的栖息地，为了建造农场和房屋。 后接动词原形make，表目的，用in order to。其他选项后接从句或不完整。 49．句意：我们没有足够的食物喂养幼鹤。 人类过度捕捞捕猎，导致丹顶鹤食物短缺，应选enough“足够的”。little、a little表少量，many修饰可数名词，均不符合语境。

52．句意：然而，蜜蜂的数量正在下降，科学家们对此感到担忧。前句讲述蜜蜂的重要性，后句说明数量下降的现状，需用转折副词。选项“however”符合语义，表示“然而”，句首首字母大写。 53．句意：蜜蜂的数量正在下降。“the number of bees...dropping”表示“蜜蜂的数量正在下降”，the number of作主语视为单数，需用be动词与现在分词构成现在进行时。选项“be”的第三人称单数形式“is”符合语法。 54．句意：科学家们对此感到担忧。“scientists are...”表示“科学家们感到担忧”，需用形容词作表语。选项“worry”的形容词形式“worried”符合语义，表示“担忧的”。 55．句意：想想你能做些什么来保护地球上最神奇的动物之一。“what you can

65．scientists 【导语】本文主要讲述了大熊猫的黑白毛色在野外环境中的保护作用及其科学原理。 【详解】56．句意：在野外，老虎能像我们一样轻易看见熊猫吗？easy“容易的”，空处修饰动词see，应用副词形式easily，且“as+副词原级+as”是固定搭配，所以空处是副词原级。故填easily。 57．句意：两年前，一项研究表明，它们的黑白毛色有助于它们在野外隐蔽。show“展示”，结合“two years ago”可知，句子用一般过去时，谓语动词用过去式。故填showed。 58．句意：如果我们想了解动物的颜色，我们需要看看它们生活的地方。understand“理解”，want to do“想做某事”是固定搭配，空处是动词原形。故填understand。 59．句意：布里斯托大学的Tim Caro在一份报告中表示。university“大学”，University of Bristol“布里斯托大学”，是固定表达。故填University。 60．句意：根据Caro的说法，野生大熊猫生活在中国西南地区的山区。mountain“山”，此处用其复数形式表泛指。故填mountains。 61．句意：那儿有阴凉的地方和多雪的地区。area“地区”，结合“places”可知，空处也应是复数形式。故填areas。 62．句意：它们的颜色使它们在野外躲藏得很好。excellent“优秀的”，make sb adj.“使某人怎么样”是固定搭配，空处是形容词。故填excellent。 63．句意：它们永远无法储存足够的脂肪来度过冬天。enough“足够的”，修饰名词fat。故填enough。 64．句意：这使得其他动物更难看到它们。hard“困难的”，结合“This makes it even...”和语境可知，此处的even修饰比较级形式，空处应是harder，作宾语补足语。故填harder。 65．句意：一些科学家还发现，它们身体其他部位的颜色具有不同的作用。scientist“科学家”，是可数名词，some后接其复数形式。故填scientists。 66．connection

【详解】66．句意：蜜蜂是这种联系最好的例子之一。该处需一个名词，在句中作介词of的宾语；connect的名词变形为connection“联系”。 67．句意：天气温暖时，我们能看见蜜蜂在花丛中飞舞。该处需一个名词复数，在句中作among的宾语；“among”表示“在……之间”，提示后面接可数名词复数；flower为可数名词，复数形式直接加s，故填flowers。 68．句意：它们把花粉从一朵花带到另一朵花，这个行为帮助植物茁壮成长。主语是单数可数名词，一般现在时谓语动词使用三单形式，help三单为helps。 69．句意：事实上，世界上大约百分之八十的植物没有它们的劳作就无法生长。前文讲蜜蜂传粉助力植物生长，提示语义与“没有”相关；结合句子逻辑，缺少蜜蜂工作植物无法生长，故填without。 70．句意：出于这个原因，许多科学家认为蜜蜂是这颗星球上最重要的动物。范围“on this planet”提示语义需要表达“最重要的”；定冠词the后要求使用形容词最高级，important多音节词最高级加most，故填most important。 71．句意：它们建造蜂巢来储存蜂蜜。“create honeycombs”提示语义是筑巢的目的；不定式结构to do可表行为目的，故填to store。 72．句意：另一件有趣的事是蜜蜂可以通过跳舞告诉其他同伴食物的位置以及距离。“where”和“how far away the food is”提示语义是并列的两条信息；并列连词and用于连接并列从句，故填and。 73．句意：蜜蜂在我们星球的生态系统中发挥着重要作用固定搭配play a part in表示“在……中起作用”，提示需要不定冠词；important以元音音素开头，需使用an。 74．句意：现在科学家十分担忧，因为蜜蜂的数量正在下降。“Now”提示语义为当下正在发生的动作；be动词is后要求使用现在分词构成现在进行时，drop现在分词为dropping。 75．句意：我们应当做一些有用的事来保护它们。前文指代bees，提示语义代指蜜蜂；动词后需用人称代词宾格，they宾格形式为them。 76．例文： Amazing Animals I Know    I used to think giraffes were just tall animals with long necks. But now I know they are more amazing than I thought.     Giraffes live in African grasslands. Their long necks help them reach leaves on tall trees, which other animals can’t get. They have long legs that let them run fast to escape predators. What’s more, giraffes only drink water once every few days because they get most water from the leaves they eat.     I feel surprised by their special abilities. It’s amazing how animals adapt to their habitats. We should protect giraffes and their environment so they can live happily in the wild. 【详解】写作步骤 [第一步：审题立意] 确定文体：说明文，标题Amazing Animals I Know，时态混合一般过去时、一般现在时 明确要点：①过去你对这种动物的认识；②现在你对它的新了解（特征、习性）；③谈谈你的感受与想法； 注意事项：词数100词左右，必须用上提示词used to, amazing, habitat, adapt to；覆盖全部要点，文中不能出现真实姓名、校名、地名 [第二步：构思布局] 三段式结构： 开头段：介绍过去对动物的固有印象，对应要点① 主体段：讲解如今新学到的特征、生活习性，对应要点② 结尾段：抒发个人感受与观点，升华主题，对应要点③   [第三步：要点展开] 要点一：过去对动物的认识 核心表达：I used to think giraffes were just tall animals with long necks.
