These marsupials spend about 18 to 20 hours a day 11 in eucalyptus trees. Their diet consists entirely of eucalyptus leaves, which are tough and poisonous to most animals. To digest these leaves, koalas have a special organ (器官) 12 a caecum (盲肠). Baby koalas, known as joeys, are born the size of a peanut. They immediately crawl into their mother’s pouch, where they 13 for about six months. After leaving the pouch, the joey rides on its mother’s back for another six months, learning 14 food and avoid dangers. Sadly, koalas face serious threats. Due to deforestation (滥伐森林), nearly 80% of their habitat 15 in the past 20 years. Bushfires, worsened by climate change, have killed 16 koalas recently. Scientists warn that if no 17 is taken, koalas may die out by 2050. Fortunately, conservation (保护) efforts 18 now. Volunteers plant eucalyptus trees, and wildlife hospitals rescue injured koalas. Australians even built special “koala bridges” to help them cross roads safely. These gentle creatures remind us 19 the importance of protecting nature. As the famous saying goes, “We do not inherit (继承) the Earth from our ancestors (祖先); we borrow it from our children.” Protecting nature is protecting 20 . 11．A．sleep B．sleeping C．to sleep 12．A．called B．calling C．to call 13．A．stays B．stay C．stayed 14．A．find B．to find C．finding 15．A．is destroyed B．has been destroyed C．was destroyed 16．A．thousand of B．thousands of C．thousands 17．A．action B．activity C．work 18．A．make B．are being made C．made 19．A．with B．of C．for 20．A．ourselves B．we C．our 【答案】 11．B 12．A 13．B 14．B 15．B 16．B 17．A 18．B 19．B 20．A 【导语】本文主要介绍了考拉的生活习性，包括它们的作息、饮食、幼崽成长过程，同时讲述了考拉面临的生存威胁以及人们为保护考拉所做的努力，强调了保护自然的重要性。 11．句意：这些有袋动物每天大约有18到20个小时在桉树上睡觉。 结合语境，“spend+时间+doing sth”为固定搭配，意为“花费时间做某事”，此处需用动名词形式，sleeping符合语法要求。 12．句意：为了消化这些树叶，考拉有一个特殊的器官，叫做盲肠。 结合语境，此处是对“special organ”进行解释说明，意为“被叫做盲肠的特殊器官”，应用过去分词called作后置定语。 13．句意：它们立即爬进妈妈的育儿袋，在那里待大约六个月。 结合上下文，全文主要用一般现在时，主语they为复数，谓语动词需用原形，stay符合语法要求。 14．句意：离开育儿袋后，幼崽会在妈妈的背上再待六个月，学习寻找食物和躲避危险。 结合语境，“learn to do sth”为固定搭配，意为“学习做某事”，此处需用动词不定式to find。 15．句意：由于滥伐森林，在过去的20年里，它们近80%的栖息地已经被破坏。 根据时间状语“in the past 20 years”，可知此处需用现在完成时，且habitat与destroy之间为被动关系，应用现在完成时的被动语态has been destroyed。 16．句意：受气候变化加剧的森林大火最近已经杀死了成千上万的考拉。 结合语境，“成千上万的”为固定搭配thousands of，thousand前无具体数字时，需加s且接of。 17．句意：科学家警告说，如果不采取任何行动，考拉可能会在2050年灭绝。 结合语境，“take action”为固定搭配，意为“采取行动”，action符合语义。 18．句意：幸运的是，现在正在进行保护工作。 结合语境，“now”提示此处需用现在进行时，且conservation efforts与make之间为被动关系，应用现在进行时的被动语态are being made。 19．句意：这些温顺的动物提醒我们保护自然的重要性。 结合语境，“remind sb of sth”为固定搭配，意为“提醒某人某事”，of符合搭配要求。 20．句意：保护自然就是保护我们自己。 结合语境，此处指“保护我们自己”，应用反身代词ourselves；we为人称代词主格，our为形容词性物主代词，均不符。 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。 The Yangtze Finless Porpoise: Our Smiling Friend in the River The Yangtze Finless Porpoise is a cute and gentle animal living in the Yangtze River.

First, people cut down too many trees and put chemicals into the river, 25 the water becomes dirty and the porpoises lose their clean homes. Second, too many boats in 26 river make loud noises, which hurt their hearing. Some people also kill fish in the river, so the porpoises do not have enough food to eat. We must take action to save them now! We should follow the rules 27 the river clean and stop throwing rubbish into the water. We can also tell our friends and family about the danger to the porpoises and ask them to look after the river. The government wants 28 plans to protect them, too.

These animals eat dry plants in forests and fields to help stop wildfires in California. Wildfires are a big danger to parks, communities and open land. They spread fast and burn for weeks or even months. The 7 has become worse in recent years. Goats eat the dry brush that easily catches fire. Targeted grazing (定向放牧) is a smart way to 8 fires before they start. Carl McCosker watches over the goats. He began with only four goats to clear neighbor’s land. Now, his herd (羊群) has grown because many places need their help. Why are there more fires now? Scientists say summers are hotter and winters are 9 . Rain is less common than in the past. Green plants make it hard for fire to start, but dry plants help fires spread. That’s why clearing brush is so important. Carl and his team use movable pens (围栏) called sets to guide the goats. Each set is a certain area that needs clearing. The goats eat the dry plants while the team sets up the next pen. Once the goats finish eating in one set, they 10 the next until the whole area is clear. Carl’s 120 goats work for six months each year. The goats eat from morning until night, like little eating machines. This continuous 11 to eat helps clear land quickly. A group of 100 goats can clear an entire acre—the size of a football field—in just one day. During the rainy season, the goats stay in barns. In spring, new baby goats are born and soon join the work. Carl believes targeted grazing is a natural and low-cost method. What’s more, it is better than using big machines that pollute the air. He works with family, friends, and dogs to protect the goats from wild animals. “There’s no better feeling than knowing you’re making a real difference,” Carl says with a smile. He is 12 to help keep forests and people safe from wildfires. 7．A．attention B．solution C．situation D．position 8．A．prevent B．pretend C．protect D．keep 9．A．wetter B．drier C．colder D．warmer 10．A．look forward to B．go back to C．come up with D．move on to 11．A．arrangement B．amusement C．requirement D．development 12．A．confident B．proud C．excited D．satisfied 【答案】7．C 8．A 9．B 10．D 11．C 12．B 【导语】本文是一篇记叙文，文章主要讲述了利用山羊进行定向放牧以预防加州野火的情况。山羊通过吃干植物来减少火灾风险，这种方法既自然又低成本，且比使用污染空气的大型机器更有效。 7．句意：近年来情况变得更糟了。 attention注意；solution解决办法；situation情况；position位置。根据前文“Wildfires are a big danger to parks, communities and open land.”以及后文“Why are there more fires now?”可知，野火对公园、社区和开阔地构成巨大威胁，且现在火灾更多了，所以此处指的是情况变得更糟了。故选C。 8．句意：定向放牧是在火灾发生前预防火灾的一种明智方法。 prevent阻止；pretend假装；protect保护；keep保持。根据后文“That’s why clearing brush is so important.”可知，清除灌木很重要，结合常识可知，清除灌木可以预防火灾，所以此处指的是预防火灾。故选A。 9．句意：科学家表示，夏天更热，冬天更干燥。 wetter更潮湿的；drier更干燥的；colder更冷的；warmer更温暖的。根据后文“Rain is less common than in the past.”以及“but dry plants help fires spread”可知，雨水比过去少了，干植物有助于火势蔓延，所以此处指的是冬天更干燥。故选B。 10．句意：一旦山羊在一个区域吃完，它们就会转移到下一个区域，直到整个区域都被清理干净。 look forward to期待；go back to回到；come up with想出；move on to转移到。根据后文“until the whole area is clear”可知，直到整个区域都被清理干净，所以此处指的是山羊会转移到下一个区域。故选D。 11．句意：这种持续的进食需求有助于快速清理土地。 arrangement安排；amusement娱乐；requirement需求；development发展。根据前文“The goats eat from morning until night, like little eating machines.”可知，山羊从早吃到晚，就像小型的进食机器，所以此处指的是这种持续的进食需求。故选C。 12．句意：他为能帮助保护森林和人们免受野火侵袭而感到自豪。 confident自信的；proud自豪的；excited兴奋的；satisfied满意的。根据前文“Carl believes targeted grazing is a natural and low-cost method. What’s more, it is better than using big machines that pollute the air.”以及“There’s no better feeling than knowing you’re making a real difference”可知，卡尔认为定向放牧是一种自然且低成本的方法，且比使用污染空气的大型机器更好，能为保护森林和人们免受野火侵袭做出贡献，所以他应该是感到自豪的。故选B。 (C) Many people think of sharks as dangerous monsters. But human beings pose a far greater danger to these creatures than they do to us. Although shark attacks do occur, they are quite 1 . On the other hand, according to one research, humans kill 100 million sharks every year. This number is a warning that many kinds of sharks may die out. 2 should we save the sharks? The killing of sharks is a problem for the whole planet. Sharks eat other species(物种), but few creatures eat them. As sharks die off, the populations of the animals that sharks eat will 3 . This, in turn, means that the populations of the creatures that those animals eat will shrink. That includes some sea creatures that humans consume, such as shrimp. It also includes fish that eat algae(藻类), which can cause algae to spread so much that it damages coral reefs. Shrinking shark populations a fleets more than just the ocean. Ocean plants produce much of the oxygen on the planet. These plants can be harmed when changes in the shark population upset the ecosystem. Don’t use shark produets Shark liver oil is used in many popular cosmetics(化妆品). Pet foods, vitamins, energy drinks and leather goods can 4 be made from shark parts. And shark meat is sold around the world, sometimes under misleading names such as rock salmon or whitefish. Most sharks killed worldwide are hunted for their fins, which are used to make shark fin soup. The 5 is cruel: Fishermen cut the shark’s fins oil and then throw the shark back into the water. Then the shark dies slowly sometimes over several days. Sharks breathe by swimming, so a shark that can’t swim will die. Eat only sustainably(可持续地) caught seafood Sharks often die because they are caught in nets. If you eat seafood, make sure it comes from fish farms that 6 the oceans. 1．A．rare B．strange C．natural D．general 2．A．How B．When C．Why D．Where 3．A．match B．depend C．limit D．increase 4．A．even B．also C．ever D．always 5．A．process B．situation C．progress D．attitude 6．A．cut down B．care for C．keep off D．consist of 【答案】1．A 2．C 3．D 4．B 5．A 6．C 【分析】本文是一篇说明文。主要讲述鲨鱼是很危险的动物，但人类对这些生物的威胁远远大于它们对我们的威胁，并讲述这些动物的数量正在慢慢减少，以及我们应该采取什么措施保护这些生物。 1．句意：虽然鲨鱼袭击确实发生过，但非常罕见。 rare稀少的；strange奇怪的；natural自然的；general普遍。由该句中的although结合前句“human beings pose a far greater danger to these creatures than they do to us”可知,虽然鲨鱼攻击人类确实存在,但其实非常少见。故选A。 2．句意：我们应该如何拯救鲨鱼？ How如何；When什么时候；Why为什么；Where哪里。综合整段段意可知实在说明鲨鱼对海洋生态系统的平衡作用,所以是“为什么我们要拯救鲨鱼”。故选C。 3．句意：随着鲨鱼的灭绝，被鲨鱼捕食的动物的数量也会增加。 match配对；depend依赖；limit限制；increase增加。根据前句 “Shark eat other species, but few creatures eat them”那么当鲨鱼灭绝的时候,鲨鱼吃的物种当然是会增加。故选D。 4．句意：宠物食品、维生素、能量饮料和皮革制品也可以用鲨鱼的部分制成。 even甚至；also也；ever永远；always总是。根据前句“Shark liver oil is used in many popular cosmetics”可知是鲨鱼肝油被用于很多化妆品中,空格所在句意指鲨鱼其他部位也被做成各种商品,可知是“也”的关系。故选B。 5．句意：这个过程是残忍的。 process过程；situation情景；progress进步；attitude 态度。根据“Fishermen cut the shark’s fins off and then throw the shark back into the water.”可知，渔民切下鲨鱼的鳍，然后把鲨鱼扔回水里。因此是这个“过程”很残忍。故选A。 6．句意：如果你吃海鲜，确保它来自与大海隔开的渔场。 cut down砍倒；care for关心；keep off远离；consist of由……组成。根据“Shark liver oil is used in many popular cosmetics(化妆品).”可知，鲨鱼常因被网捕而死亡。因此这里应该表示如果你吃海鲜，确保它来自与大海隔开的渔场。故选C。 阅读理解 Reading comprehension (A) Teamwork in nature Honeybees: Honeybees live in hives where each bee has a different job. Worker bees collect nectar and pollen, protect the hive, and take care of baby bees. The queen bee lays eggs, and drones mate with the queen. When a worker bee finds food, it does a “waggle dance” to show other bees where the food is and how far it is. By working together, the hive gets enough food to live through winter. Meerkats: Meerkats live in groups called mobs. When most meerkats go out to look for insects and small animals to eat, one or two stay behind as lookouts. If they see a predator—like a hawk, a snake, or a fox—they make a loud call—then all meerkats hide right away. They also share food and take turns looking after the young. This way, the whole group stays safe and full. Orcas: Orcas (also called killer whales) hunt in groups called pods. When they go after food like fish or seals, they work together: some orcas chase the prey into a small group, and others attack one by one. For bigger prey like large whales, they may push the prey to the water surface so it can’t breathe. With teamwork, they can catch food that a single orca couldn’t get. 1．What does a honeybee’s “waggle dance” do? A．Help the queen lay eggs. B．Tell other bees where food is. C．Guard the hive from enemies. D．Care for baby bees. 2．Why do meerkats have lookouts while looking for food? A．To find more food. B．To teach young meerkats to hunt. C．To watch for dangerous animals. D．To take turns resting. 3．How are honeybees and orcas similar in teamwork? A．Both have a queen to lead the group. B．Both use teamwork to get food. C．Both live in mobs. D．Both have lookouts for predators. 4．The word “predator” in the meerkat paragraph most likely means ________ A．Animals that hunt other animals for food. B．Animals that are harmless to others. C．Animals that live in groups. D．Animals that lay eggs. 5．Why can orcas catch big prey in pods? A．Big prey is scared of groups. B．Big prey only lives in groups. C．Pods can swim faster than single orca. D．A single orca isn’t strong enough. 【答案】1．B 2．C 3．B 4．A 5．D 【导语】本文主要介绍了自然界中蜜蜂、猫鼬、虎鲸三种动物的团队协作方式。 1．细节理解题。根据文章中蜜蜂部分的“When a worker bee finds food, it does a ‘waggle dance’ to show other bees where the food is and how far it is.”可知，蜜蜂的“摇摆舞”是用来告诉其他蜜蜂食物的位置。故选B。 2．细节理解题。根据文章中猫鼬部分的“When most meerkats go out to look for insects and small animals to eat, one or two stay behind as lookouts. If they see a predator... they make a loud call—then all meerkats hide right away.”可知，猫鼬觅食时留下守望者是为了警惕危险动物。故选C。 3．细节理解题。根据文章中蜜蜂部分的“By working together, the hive gets enough food to live through winter.”和虎鲸部分的“With teamwork, they can catch food that a single orca couldn’t get.”可知，蜜蜂和虎鲸的团队协作都用于获取食物。故选B。 4．词句猜测题。根据“If they see a predator... they make a loud call—then all meerkats hide right away.”可知，猫鼬见到predator后会立即躲藏，说明这是一种会给它们带来危险的动物，即“捕食性动物”或“天敌”。故选A。 5．推理判断题。根据文中末句“With teamwork, they can catch food that a single orca couldn’t get.”可知，虎鲸团队能捕捉单只无法获得的猎物。由此可推断，根本原因是单只虎鲸力量不足，无法独立完成捕猎，因此需要合作。故选D。 (B) ①Animals in nature must be very clever and quick to keep safe from danger. Just like you play hide-and-seek (捉迷藏) games, animals have their own ways of hiding and staying away from some things. Their ears, noses and eyes are very important for finding danger around them. ②Some animals, like rabbits, have big ears. The large ears can hear really well, so they can listen for some sounds. These sounds may tell them there is trouble around them. Also, their eyes are on the side of their heads, letting them see around without having to turn their heads. ③Animals like chameleons can change their colour to hide from predators (捕食者) by looking like the trees and leaves when they live in them. If you can become the colour of the wall in your room, it is difficult for others to find you. How amazing it is! ④When some animals feel afraid, they will try to look big and strong. For example, porcupines can make their spikes (刺) stand up. Other animals like Opossums have different skills. Opossums don’t move when a predator is coming to them. The predator will think they are not alive and not fun to eat. So the predator will leave them. ⑤When Meerkats live in groups, they help each other. For example, one of Meerkats will watch out for (留意) danger when the others look for food. In this way, there are always more eyes looking for safety. ⑥By using their bodies and working together, animals have smart ways to keep safe in nature. 6．The writer talks about hide-and-seek games in Paragraph 1 to show ________. A．animals like playing games B．animals are smarter than people C．animals have ways to keep safe D．animals are afraid of danger 7．According to the passage, chameleons can ________ when they meet predators. A．climb up trees B．hide under leaves C．run into rooms D．change their colour 8．What can we learn from Paragraphs 4-5? A．Porcupines use spikes to carry things. B．Opossums move fast to leave predators. C．Predators will eat living Opossums. D．Meerkats live in groups to find food. 9．How does the writer show the animals’ ways to keep safe? A．By telling stories. B．By giving examples. C．By asking questions. D．By showing pictures. 10．Which is the right structure (结构) of the passage? A．①/②③④/⑤⑥ B．①②/③④⑤/⑥ C．①/②③④⑤/⑥ D．①/②③④⑤⑥ 【答案】6．C 7．D 8．D 9．B 10．C 【导语】本文是一篇说明文，主要介绍自然界的动物拥有各种聪明的自保方式，分别从听觉视觉、变色伪装、外形威慑、装死求生以及群居互助等方面展开介绍，最后总结动物依靠自身本领和协作保护自己。 6．文章第一段明确提到：“Just like you play hide-and-seek games, animals have their own ways of hiding and staying away from some things.”，由此可知作者提到捉迷藏是为了引出动物有自己保护自身安全的方式，其余选项不符合文意，因此该项正确。 7．文章第三段明确提到：“Animals like chameleons can change their colour to hide from predators”，由此可知变色龙遇到捕食者时可以改变自身颜色来隐藏自己，因此该项正确。 8．文章第五段明确提到：“When Meerkats live in groups, they help each other…when the others look for food.”，由此可知狐獴群居生活、结伴觅食避险，其余选项均与原文内容不符，因此该项正确。 9．文章第二段到第五段分别列举兔子、变色龙、豪猪、负鼠、狐獴等多种动物的自保方法，由此可知作者是通过举例子的方式介绍动物自保方式，因此该项正确。 10．文章第①段总起引出动物有自保方法；第②③④⑤段分别举例介绍不同动物的避险方式；第⑥段总结全文，因此文章结构为①/②③④⑤/⑥。 (C) Have you changed your mind after learning something new? Maybe you think one answer is right on a test (测验), but then you read the question again and choose a different one. Scientists have found that chimps can do this too. This amazing ability shows that chimps are smarter than we thought. For a long time, people believed only humans (人类) could change their ideas based on new facts. But now we know that our closest animal relatives (亲戚) share this special ability with us. In Uganda, Africa, researchers made a clever test for the chimps. They put food in one of the two boxes—a yellow box and a blue box, and gave the chimps clues (线索) about where the food was. The researchers shook (摇晃) the yellow box that had wood inside. The shaking made a noise, so it sounded like the food was in the yellow box. The chimps listened carefully and picked up this yellow box. But here’s the interesting part: after that, the researchers showed them what was really in the blue box—a piece of apple! When the chimps saw this new evidence, many of them changed their minds and picked up the blue box instead. This finding is very exciting because it shows that chimps can think in a clear way. That means chimps can have an idea, look for facts, and then change their minds when they learn something new. This is what a four-year-old human child can do. What does this mean for us? It tells us that animals are often smarter than we think. Chimps don’t just act without thinking. They can think, understand, and change what they do when things are different. This beautiful finding should make us treat all living things with more respect and care. The world is full of amazing minds, not just human ones. 11．What can we know from the test in Uganda? A．The researchers shook the yellow box to make the chimps relaxed. B．The chimps first picked up the yellow box but then the blue one instead. C．The chimps picked up the blue box after seeing the wood. D．The food was first put in the yellow box, and then put in the blue box. 12．What does the word “evidence” in Paragraph 2 most probably mean? A．Game. B．Fact. C．Wood. D．Test. 13．Which is NOT true about the finding of the research? A．Chimps are often smarter than we think. B．Chimps can think in a clear way like a four-year-old child. C．Chimps can make new facts to help them change their minds. D．Chimps may change their minds after learning something new. 14．The writer writes the passage in order to make us feel ________. A．respectful of all living things B．excited to have so many animal friends C．hopeful of having smarter chimps D．interested in finding out more about chimps 【答案】11．B 12．B 13．C 14．A 【导语】本文介绍了科学家通过实验发现黑猩猩也能像人类一样根据新证据改变想法，揭示了动物的认知能力远超人类以往的认知。 11．根据第二段“The chimps listened carefully and picked up this yellow box. But here’s the interesting part: after that, the researchers showed them what was really in the blue box—a piece of apple! When the chimps saw this new evidence, many of them changed their minds and picked up the blue box instead.”可知，黑猩猩先拿起黄色盒子，之后又选择了蓝色盒子。 12．根据第二段“When the chimps saw this new evidence”及上下文语境可知，evidence在此处指研究中的“事实、证据”，与fact 含义相近。 13．根据第三段“This means chimps can have an idea, look for facts, and then change their minds when they learn something new.”和第四段“Chimps don’t just act without thinking. They can think, understand, and change what they do when things are different.”可知，黑猩猩并不能制造新事实来帮助自己改变想法，该表述错误。 14．根据最后一段“This beautiful finding should make us treat all living things with more respect and care.”可知，作者写这篇文章是为了让我们学会尊重所有生物。 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 $ Unit 5 Wild animals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。 There are many kinds of wildlife in Jiuzhaigou Nature Reserve (保护区).

These marsupials spend about 18 to 20 hours a day 11 in eucalyptus trees. Their diet consists entirely of eucalyptus leaves, which are tough and poisonous to most animals. To digest these leaves, koalas have a special organ (器官) 12 a caecum (盲肠). Baby koalas, known as joeys, are born the size of a peanut. They immediately crawl into their mother’s pouch, where they 13 for about six months. After leaving the pouch, the joey rides on its mother’s back for another six months, learning 14 food and avoid dangers. Sadly, koalas face serious threats. Due to deforestation (滥伐森林), nearly 80% of their habitat 15 in the past 20 years. Bushfires, worsened by climate change, have killed 16 koalas recently. Scientists warn that if no 17 is taken, koalas may die out by 2050. Fortunately, conservation (保护) efforts 18 now. Volunteers plant eucalyptus trees, and wildlife hospitals rescue injured koalas. Australians even built special “koala bridges” to help them cross roads safely. These gentle creatures remind us 19 the importance of protecting nature.

However, this lovely animal is 24 great danger now. There are only about 1,000 Yangtze Finless Porpoises left in the wild. Why? First, people cut down too many trees and put chemicals into the river, 25 the water becomes dirty and the porpoises lose their clean homes. Second, too many boats in 26 river make loud noises, which hurt their hearing. Some people also kill fish in the river, so the porpoises do not have enough food to eat. We must take action to save them now! We should follow the rules 27 the river clean and stop throwing rubbish into the water.

He studies one 9 of North American butterfly. Just like a migrating (迁徙) bird, this butterfly travels about 4,000 kilometres south in autumn. The 10 facts about the butterfly have attracted Dr. Taylor’s attention. In Mexico, the butterflies always return to the same small piece of forest, which is only 20 kilometres wide. Here, about 230 million butterflies spend the winter. They can cover some trees almost 11 .

Black cats are unique in human culture. Some see them as bad luck, while others believe they bring good fortune. Many stories and old sayings help spread these ideas 17 . Bad Luck for Black Cats It seems that the 18 between bad luck and black cats dates all the way back to the 13th century. Although it’s not known how and why cats had something to do with the devil (魔鬼) in the Middle Ages, the belief was so 19 that the black cats were rounded up and killed during the Black Death pandemic (黑死病) around 1348 CE, simply because many people believed witches had taken in black cats as companions. In many European countries where cats are still seen as bad luck, it’s 20 unlucky if a black cat crosses your path from right to left. A．straight  B．single  C． remains  D．considers  E. aboard Black Cats as Good Luck It seems that the influence of ancient Egyptians and their love for cats 21 in some European cultures. Historically, sailors and their wives believed in the good luck power of the black cat. And this custom continues today: some fishermen keep such cats 22 , while women keep black cats at home for a double share of luck. In Russia, all cats are thought of as lucky. Many Russian families keep cats as beloved pets. Japanese culture also 23 black cats as symbols of good luck. They think black cats bring happiness. This is especially important for 24 women, as owning a black cat is believed to attract fine suitors (追求者) . These widespread customs show how black cats have become special animals in different cultures around the world. 完形填空 Choose the best answer and complete the passage (A) Elephants are among the most intelligent animals on Earth. They have an amazing communication system that scientists are just beginning to understand. Elephants can produce sounds 1 low for human ears to hear. This infrasound can travel over 10 kilometers, allowing distant elephants to “talk” to each other. When danger 2 , older elephants will warn the herd by making special rumbling sounds. Baby elephants learn these important calls from their mothers and aunts. The whole herd 3 together to protect the young. Besides sounds, elephants use body language to communicate. A happy elephant will flap its ears and wag its tail. An angry elephant may trumpet loudly and 4 its ears out to look bigger. Sadly, elephant populations are declining due to habitat loss and poaching. Conservationists are working hard to 5 these magnificent creatures.

These animals eat dry plants in forests and fields to help stop wildfires in California. Wildfires are a big danger to parks, communities and open land. They spread fast and burn for weeks or even months. The 7 has become worse in recent years. Goats eat the dry brush that easily catches fire. Targeted grazing (定向放牧) is a smart way to 8 fires before they start. Carl McCosker watches over the goats. He began with only four goats to clear neighbor’s land. Now, his herd (羊群) has grown because many places need their help. Why are there more fires now? Scientists say summers are hotter and winters are 9 . Rain is less common than in the past. Green plants make it hard for fire to start, but dry plants help fires spread. That’s why clearing brush is so important. Carl and his team use movable pens (围栏) called sets to guide the goats. Each set is a certain area that needs clearing. The goats eat the dry plants while the team sets up the next pen. Once the goats finish eating in one set, they 10 the next until the whole area is clear. Carl’s 120 goats work for six months each year. The goats eat from morning until night, like little eating machines. This continuous 11 to eat helps clear land quickly. A group of 100 goats can clear an entire acre—the size of a football field—in just one day. During the rainy season, the goats stay in barns. In spring, new baby goats are born and soon join the work. Carl believes targeted grazing is a natural and low-cost method. What’s more, it is better than using big machines that pollute the air. He works with family, friends, and dogs to protect the goats from wild animals. “There’s no better feeling than knowing you’re making a real difference,” Carl says with a smile.

But human beings pose a far greater danger to these creatures than they do to us. Although shark attacks do occur, they are quite 1 . On the other hand, according to one research, humans kill 100 million sharks every year. This number is a warning that many kinds of sharks may die out. 2 should we save the sharks? The killing of sharks is a problem for the whole planet. Sharks eat other species(物种), but few creatures eat them. As sharks die off, the populations of the animals that sharks eat will 3 . This, in turn, means that the populations of the creatures that those animals eat will shrink. That includes some sea creatures that humans consume, such as shrimp. It also includes fish that eat algae(藻类), which can cause algae to spread so much that it damages coral reefs. Shrinking shark populations a fleets more than just the ocean. Ocean plants produce much of the oxygen on the planet. These plants can be harmed when changes in the shark population upset the ecosystem. Don’t use shark produets Shark liver oil is used in many popular cosmetics(化妆品). Pet foods, vitamins, energy drinks and leather goods can 4 be made from shark parts. And shark meat is sold around the world, sometimes under misleading names such as rock salmon or whitefish. Most sharks killed worldwide are hunted for their fins, which are used to make shark fin soup. The 5 is cruel: Fishermen cut the shark’s fins oil and then throw the shark back into the water. Then the shark dies slowly sometimes over several days. Sharks breathe by swimming, so a shark that can’t swim will die.

Worker bees collect nectar and pollen, protect the hive, and take care of baby bees. The queen bee lays eggs, and drones mate with the queen. When a worker bee finds food, it does a “waggle dance” to show other bees where the food is and how far it is. By working together, the hive gets enough food to live through winter. Meerkats: Meerkats live in groups called mobs. When most meerkats go out to look for insects and small animals to eat, one or two stay behind as lookouts. If they see a predator—like a hawk, a snake, or a fox—they make a loud call—then all meerkats hide right away. They also share food and take turns looking after the young. This way, the whole group stays safe and full. Orcas: Orcas (also called killer whales) hunt in groups called pods. When they go after food like fish or seals, they work together: some orcas chase the prey into a small group, and others attack one by one. For bigger prey like large whales, they may push the prey to the water surface so it can’t breathe. With teamwork, they can catch food that a single orca couldn’t get. 1．What does a honeybee’s “waggle dance” do? A．Help the queen lay eggs. B．Tell other bees where food is. C．Guard the hive from enemies. D．Care for baby bees. 2．Why do meerkats have lookouts while looking for food? A．To find more food. B．To teach young meerkats to hunt. C．To watch for dangerous animals. D．To take turns resting. 3．How are honeybees and orcas similar in teamwork? A．Both have a queen to lead the group. B．Both use teamwork to get food. C．Both live in mobs. D．Both have lookouts for predators. 4．The word “predator” in the meerkat paragraph most likely means ________ A．Animals that hunt other animals for food. B．Animals that are harmless to others. C．Animals that live in groups. D．Animals that lay eggs. 5．Why can orcas catch big prey in pods? A．Big prey is scared of groups. B．Big prey only lives in groups. C．Pods can swim faster than single orca. D．A single orca isn’t strong enough. (B) ①Animals in nature must be very clever and quick to keep safe from danger. Just like you play hide-and-seek (捉迷藏) games, animals have their own ways of hiding and staying away from some things. Their ears, noses and eyes are very important for finding danger around them. ②Some animals, like rabbits, have big ears. The large ears can hear really well, so they can listen for some sounds. These sounds may tell them there is trouble around them. Also, their eyes are on the side of their heads, letting them see around without having to turn their heads. ③Animals like chameleons can change their colour to hide from predators (捕食者) by looking like the trees and leaves when they live in them. If you can become the colour of the wall in your room, it is difficult for others to find you. How amazing it is! ④When some animals feel afraid, they will try to look big and strong. For example, porcupines can make their spikes (刺) stand up. Other animals like Opossums have different skills. Opossums don’t move when a predator is coming to them. The predator will think they are not alive and not fun to eat. So the predator will leave them. ⑤When Meerkats live in groups, they help each other. For example, one of Meerkats will watch out for (留意) danger when the others look for food. In this way, there are always more eyes looking for safety. ⑥By using their bodies and working together, animals have smart ways to keep safe in nature. 6．The writer talks about hide-and-seek games in Paragraph 1 to show ________. A．animals like playing games B．animals are smarter than people C．animals have ways to keep safe D．animals are afraid of danger 7．According to the passage, chameleons can ________ when they meet predators. A．climb up trees B．hide under leaves C．run into rooms D．change their colour 8．What can we learn from Paragraphs 4-5? A．Porcupines use spikes to carry things. B．Opossums move fast to leave predators. C．Predators will eat living Opossums. D．Meerkats live in groups to find food. 9．How does the writer show the animals’ ways to keep safe? A．By telling stories. B．By giving examples. C．By asking questions. D．By showing pictures. 10．Which is the right structure (结构) of the passage? A．①/②③④/⑤⑥ B．①②/③④⑤/⑥ C．①/②③④⑤/⑥ D．①/②③④⑤⑥ (C) Have you changed your mind after learning something new? Maybe you think one answer is right on a test (测验), but then you read the question again and choose a different one. Scientists have found that chimps can do this too. This amazing ability shows that chimps are smarter than we thought. For a long time, people believed only humans (人类) could change their ideas based on new facts. But now we know that our closest animal relatives (亲戚) share this special ability with us. In Uganda, Africa, researchers made a clever test for the chimps. They put food in one of the two boxes—a yellow box and a blue box, and gave the chimps clues (线索) about where the food was. The researchers shook (摇晃) the yellow box that had wood inside. The shaking made a noise, so it sounded like the food was in the yellow box. The chimps listened carefully and picked up this yellow box. But here’s the interesting part: after that, the researchers showed them what was really in the blue box—a piece of apple! When the chimps saw this new evidence, many of them changed their minds and picked up the blue box instead. This finding is very exciting because it shows that chimps can think in a clear way. That means chimps can have an idea, look for facts, and then change their minds when they learn something new. This is what a four-year-old human child can do. What does this mean for us? It tells us that animals are often smarter than we think. Chimps don’t just act without thinking. They can think, understand, and change what they do when things are different. This beautiful finding should make us treat all living things with more respect and care. The world is full of amazing minds, not just human ones. 11．What can we know from the test in Uganda? A．The researchers shook the yellow box to make the chimps relaxed. B．The chimps first picked up the yellow box but then the blue one instead. C．The chimps picked up the blue box after seeing the wood. D．The food was first put in the yellow box, and then put in the blue box. 12．What does the word “evidence” in Paragraph 2 most probably mean? A．Game. B．Fact. C．Wood. D．Test. 13．Which is NOT true about the finding of the research? A．Chimps are often smarter than we think. B．Chimps can think in a clear way like a four-year-old child. C．Chimps can make new facts to help them change their minds. D．Chimps may change their minds after learning something new. 14．The writer writes the passage in order to make us feel ________. A．respectful of all living things B．excited to have so many animal friends C．hopeful of having smarter chimps D．interested in finding out more about chimps 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 $
