The small ant is native to South America, but has spread to many countries in the world, causing huge harm to agriculture and ecosystems. It not only destroys crops and farms but also kills large numbers of native insects and other animals. The ant’s painful sting (蜇伤) can cause serious allergies (过敏) in humans, which might even lead to death. The Minister for Agriculture calls these ants “super pests” because they do great harm to society, economy, and the environment. Red fire ants were first found in Australia in 2001. They have largely been contained within the state of Queensland since then. However, Australia’s Invasive Species Council (ISC) says the ants are spreading across the country because of flood waters. They are holding onto each other to form “rafts (木筏)” on the water. An ISC statement said, “Red fire ants are more active before or after rainfall and can form large floating rafts, which move with the flow of the water to find places to stand in new areas.” It warned that the red fire ants would reach “every corner of Australia” if the current (目前的) outbreak was not under control. 16．What’s the meaning of the underlined word “invasive” in Chinese? A．入侵的 B．土著的 C．骄傲的 D．养殖的 17．What harm can red fire ants cause? ①They can destroy crops and farms. ②They can kill native insects and other animals. ③Their stings can cause allergies and even death in humans. ④They can pollute the air around them. A．①②③ B．②③④ C．①③④ D．①②④ 18．How do red fire ants spread to other areas in Australia? A．By boat. B．By water. C．By air. D．By wind. 19．Why does the writer mention the ISC statement? A．To explain why red fire ants are good at hugging each other. B．To study why red fire ants can form “rafts” on the water. C．To tell us red fire ants spread very quickly through flood waters. D．To show the harm of red fire ants to the environment. 20．What’s the main idea of the passage? A．Red fire ants are super pests. B．Australia is facing all kinds of dangers. C．People should try their best to kill red fire ants. D．Deadly red fire ants are spreading across Australia. B Whether you love them or hate them, there’s no doubt that spiders are amazing animals. In a 2017 study, scientists showed that some people are born with a fear of them. 21 . So what do you think? Should people learn to love spiders? Yes—spiders are helpful to humans. The truth is, spiders work for humans to clear our homes and gardens of all the pests (害虫). Spiders are considered to be the friends to gardeners. 22 . Spiders are amazing animals. They have many talents, including making silk from their bodies, which is among the strongest and most flexible (柔韧的) natural materials on Earth. 23 . In fact, they usually try to get away from people or hide. Spiders are an important part of the ecosystem (生态系统), so people should learn to love them if humans want to protect the environment. No—people fear spiders for good reasons. With their many eyes and eight legs, spiders look scary. 24 . The giant house spider can move at half a metre in a second. Without even knowing them, they may have climbed up your leg. It’s no wonder so many people are scared of spiders, and maybe it’s wise to feel fear. 25 . So we should learn to protect spiders instead of doing harm to them. They are also our friends. But not all spiders are harmless to humans, so you still have to be careful not to get bitten by a spider. A．They also move so fast B．However, others think they are amazing C．Some small spiders are liked by some children D．And spiders teach us how to make a perfect web E．In a word, spiders play an important role in nature F．This is because they eat lots of pests that harm plants G．Spiders may look strange, but they don’t want to harm humans 三、任务型阅读（每空2分，共10分） Police dogs are given special training to help the police with their work. Many different types of dogs can be trained to do this work, but the best known ones are German shepherds and bloodhounds. In Britain, police dogs usually have a 13-week training course and many dogs fail. Not all dogs make good police dogs. They must be completely trustworthy and honest. Most police dogs live with their handlers as part of the family, but they are not pets. They are working dogs and they have a job to do. Police dogs are trained to chase and hold people who are trying to get away from the police. Police dogs are not vicious animals. They are trained to hold on to people until their handler tells them to let go. Police dogs often go into dangerous places and they are given special vests to protect them from knife and gun attacks. Dogs are not only trained to chase and catch criminals. They are also used for following suspects or finding missing people. This is because some dogs, such as bloodhounds, have a very good sense of smell and can be trained to recognize certain types of smells. Some dogs are used to find survivors after earthquakes or explosions and some are specially trained to find dead bodies. In many countries dogs are used in airports to check luggage for drugs and bombs. Labradors, spaniels and beagles are used for this because they are friendly dogs and people are not afraid of them. 26．How long does the training course for police dogs usually last in Britain? 27．What protects police dogs when they go into dangerous places? 28．Are people afraid of dogs like Labradors, spaniels and beagles when they are checking luggage in airports? Why? 29．What qualities should a good police dog have? 30．Why can some dogs be used to find missing people? 请根据短文内容及首字母提示，填写所缺单词。 British scientist Jane Goodall, known for her great studies of chimpanzees (黑猩猩), died on Oct 1, 2025 at the age of 91. Born in England in 1934, Goodall was so c 1 about wild animals that she always searched for the information online and she also dreamed of w 2 with them in Africa. However, her poor family couldn’t help her, so she worked to save money for her trip. In July 1960, Goodall f 3 traveled to Tanzania and entered the little-known world of wild chimpanzees. Over the next 60 years, Goodall’s findings c 4 how people understand human relationships with chimpanzees and introduced a new m 5 to study wildlife. Goodall’s research was amazing because she lived closely with wild chimpanzee groups to learn about their social lives. She even gave a n 6 to each chimp and formed close relationships with them, learning how similar they were to us. She saw that chimpanzees have different personalities (性格). Two of Goodall’s most important findings came in 1960. That year, she saw a group of chimpanzees e 7 meat, challenging the old idea that chimps only ate plants. She also saw something even more s 8 : male (雄性的) chimpanzee making and using tools. Since then, scientists have found evidence(证据) of tool use in the animal world. Besides her findings, Goodall traveled the world to speak about the d 9 situations chimpanzees are facing. “As they can’t speak for t 10 , that’s why I’m here.” Goodall told National Geographic magazine. 7 / 10 学科网（北京）股份有限公司 $ 限时练习：40min 完成时间： 月 日 天气： 寒假作业04 反身代词/情态动词/连词 反身代词 反身代词即人称代词的反身形式，它所指代的人或物与主语一致,在句中可以起到强调作用。 如:Mike cannot look after himself,迈克不能照顾自己。 The children enjoyed themselves very much at the Lantern Festival 孩子们在元宵节那天玩得非常高兴。 They kept the secret to themselves.他们保守着这个秘密。 I painted the room myself.我自己粉刷了房间。 【易错提醒】反身代词和它所指代的对象在人称、性别、数上必须保持一致。 英语中的反身代词如下: 人称 单数 复数 第一人称 myself ourselves 第二人称 yourself yourselves 第三人称 himself herself itself themselves 【易错提醒】1.第一人称和第二人称的反身代词是由形容词性物主代词加上self或selves构成,第三 人称的反身代词是由代词宾格加上self或selves构成。 2.当所指代的对象性别不详时，我们可以用themself代替himself或herself. 3.反身代词在句中不能单独做主语。如: Myself can finish my homework.

Don’t keep your worries to y . 【答案】yourself/ourself 【详解】句意：当你遇到困难时，可以寻求帮助。不要把烦恼留给自己。keep sth. to oneself意为“将某物保留给自己”，所以空处需要用反身代词，要和句子的逻辑主语保持一致，句子的逻辑主语为you，所以对应的反身代词为yourself。故填yourself。 3．In the age of AI, teenagers must be able to think independently and decide for (they) wisely. 【答案】themselves 【详解】句意：在人工智能时代，青少年必须能够独立思考并明智地为自己做决定。for是介词，此处主语“teenagers”和宾语指代同一群体，需用反身代词；they的反身代词是themselves。故填themselves。 4．Boys and girls, ask y what you really want before choosing a job. 【答案】yourselves/ourselves 【详解】句意：孩子们，在选择工作之前问问你们自己真正想要什么。根据“Boys and girls, ask…what you really want before choosing a job.”以及首字母提示可知，此处指问你们自己，yourselves“你们自己”，符合语境。故填yourselves。 5．Miss Guo always looks at in the mirror before going out.

The small ant is native to South America, but has spread to many countries in the world, causing huge harm to agriculture and ecosystems. It not only destroys crops and farms but also kills large numbers of native insects and other animals. The ant’s painful sting (蜇伤) can cause serious allergies (过敏) in humans, which might even lead to death. The Minister for Agriculture calls these ants “super pests” because they do great harm to society, economy, and the environment. Red fire ants were first found in Australia in 2001. They have largely been contained within the state of Queensland since then. However, Australia’s Invasive Species Council (ISC) says the ants are spreading across the country because of flood waters. They are holding onto each other to form “rafts (木筏)” on the water. An ISC statement said, “Red fire ants are more active before or after rainfall and can form large floating rafts, which move with the flow of the water to find places to stand in new areas.” It warned that the red fire ants would reach “every corner of Australia” if the current (目前的) outbreak was not under control. 16．What’s the meaning of the underlined word “invasive” in Chinese? A．入侵的 B．土著的 C．骄傲的 D．养殖的 17．What harm can red fire ants cause? ①They can destroy crops and farms. ②They can kill native insects and other animals. ③Their stings can cause allergies and even death in humans. ④They can pollute the air around them. A．①②③ B．②③④ C．①③④ D．①②④ 18．How do red fire ants spread to other areas in Australia? A．By boat. B．By water. C．By air. D．By wind. 19．Why does the writer mention the ISC statement? A．To explain why red fire ants are good at hugging each other. B．To study why red fire ants can form “rafts” on the water. C．To tell us red fire ants spread very quickly through flood waters. D．To show the harm of red fire ants to the environment. 20．What’s the main idea of the passage? A．Red fire ants are super pests. B．Australia is facing all kinds of dangers. C．People should try their best to kill red fire ants. D．Deadly red fire ants are spreading across Australia. 【答案】16．A 17．A 18．B 19．C 20．D 【导语】本文是一篇生态类说明文，介绍了入侵物种红火蚁在澳大利亚的传播情况、危害及扩散原因，强调了其对生态系统和社会的威胁。 16．词句猜测题。根据第一段“Australia’s ecosystems are in danger because of the invasion of the red fire ant”及后文描述可知，红火蚁是从南美洲传播到其他国家的有害物种，因此“invasive”意为“入侵的”。故选A。 17．细节理解题。根据第二段“It not only destroys crops and farms but also kills large numbers of native insects and other animals. The ant’s painful sting can cause serious allergies in humans, which might even lead to death.”可知，①②③均正确；文中未提及红火蚁污染空气。故选A。 18．细节理解题。根据第三段“However, Australia’s Invasive Species Council says the ants are spreading across the country because of flood waters.”可知，红火蚁通过洪水扩散。故选B。 19．推理判断题。根据“An ISC statement said, ‘Red fire ants are more active before or after rainfall and can form large floating rafts, which move with the flow of the water to find places to stand in new areas.’ It warned that the red fire ants would reach ‘every corner of Australia’ if the current (目前的) outbreak was not under control.”可知，作者提及ISC的声明是为了说明红火蚁通过洪水迅速传播的情况。故选C。 20．主旨大意题。全文围绕红火蚁在澳大利亚的扩散、危害及原因展开，核心内容是“致命的红火蚁正在澳大利亚扩散”。故选D。 B Whether you love them or hate them, there’s no doubt that spiders are amazing animals. In a 2017 study, scientists showed that some people are born with a fear of them. 21 . So what do you think? Should people learn to love spiders? Yes—spiders are helpful to humans. The truth is, spiders work for humans to clear our homes and gardens of all the pests (害虫). Spiders are considered to be the friends to gardeners. 22 . Spiders are amazing animals. They have many talents, including making silk from their bodies, which is among the strongest and most flexible (柔韧的) natural materials on Earth. 23 . In fact, they usually try to get away from people or hide. Spiders are an important part of the ecosystem (生态系统), so people should learn to love them if humans want to protect the environment. No—people fear spiders for good reasons. With their many eyes and eight legs, spiders look scary. 24 . The giant house spider can move at half a metre in a second. Without even knowing them, they may have climbed up your leg. It’s no wonder so many people are scared of spiders, and maybe it’s wise to feel fear. 25 . So we should learn to protect spiders instead of doing harm to them. They are also our friends. But not all spiders are harmless to humans, so you still have to be careful not to get bitten by a spider. A．They also move so fast B．However, others think they are amazing C．Some small spiders are liked by some children D．And spiders teach us how to make a perfect web E．In a word, spiders play an important role in nature F．This is because they eat lots of pests that harm plants G．Spiders may look strange, but they don’t want to harm humans 【答案】21．B 22．F 23．G 24．A 25．E 【导语】本文主要介绍了蜘蛛。 21．根据“In a 2017 study, scientists showed that some people are born with a fear of them.”可知，上文提到有些人天生怕蜘蛛，此处应是另外一些人有不同看法，承接下文的“你觉得呢？”。选项B“然而，其他人认为它们很神奇”符合语境。故选B。 22．根据“Spiders are considered to be the friends to gardeners.”可知，蜘蛛被认为是园丁的朋友，此处应是解释原因。选项F“这是因为它们吃了很多危害植物的害虫”符合语境。故选F。 23．根据“They have many talents, including making silk from their bodies”“In fact, they usually try to get away from people or hide.”可知，上文讲蜘蛛能力，下文说蜘蛛会避开人，此处需要一个句子承上启下。选项G“蜘蛛可能看起来很奇怪，但它们不想伤害人类”符合语境。故选G。 24．根据“The giant house spider can move at half a metre in a second.”可知，巨大的家蜘蛛每秒可以移动半米。选项A“它们也移动得很快”符合语境。故选A。 25．根据“So we should learn to protect spiders instead of doing harm to them. They are also our friends.”可知，此处总结概括蜘蛛的作用。选项E“总之，蜘蛛在自然界中起着重要作用”符合语境。故选E。 三、任务型阅读（每空2分，共10分） Police dogs are given special training to help the police with their work. Many different types of dogs can be trained to do this work, but the best known ones are German shepherds and bloodhounds. In Britain, police dogs usually have a 13-week training course and many dogs fail. Not all dogs make good police dogs. They must be completely trustworthy and honest. Most police dogs live with their handlers as part of the family, but they are not pets. They are working dogs and they have a job to do. Police dogs are trained to chase and hold people who are trying to get away from the police. Police dogs are not vicious animals. They are trained to hold on to people until their handler tells them to let go. Police dogs often go into dangerous places and they are given special vests to protect them from knife and gun attacks. Dogs are not only trained to chase and catch criminals. They are also used for following suspects or finding missing people. This is because some dogs, such as bloodhounds, have a very good sense of smell and can be trained to recognize certain types of smells. Some dogs are used to find survivors after earthquakes or explosions and some are specially trained to find dead bodies. In many countries dogs are used in airports to check luggage for drugs and bombs. Labradors, spaniels and beagles are used for this because they are friendly dogs and people are not afraid of them. 26．How long does the training course for police dogs usually last in Britain? 27．What protects police dogs when they go into dangerous places? 28．Are people afraid of dogs like Labradors, spaniels and beagles when they are checking luggage in airports? Why? 29．What qualities should a good police dog have? 30．Why can some dogs be used to find missing people? 【答案】26．The training course usually lasts 13 weeks. 27．Special vests protect them. 28．No, because these dogs are friendly and people are not afraid of them. 29．They must be completely trustworthy and honest. 30．Because they have a very good sense of smell and can be trained to recognize certain smells. 【导语】本文是一篇关于警犬训练与职能的说明文，主要讲了警犬的选拔标准、训练过程、保护装备及其在警务工作中的多样用途。 26．根据“In Britain, police dogs usually have a 13-week training course”可知，英国警犬的训练课程通常持续13周。故填The training course usually lasts 13 weeks. 27．根据“they are given special vests to protect them from knife and gun attacks”可知，警犬会穿着特殊防护背心以保护它们。故填Special vests protect them. 28．根据“Labradors, spaniels and beagles are used for this because they are friendly dogs and people are not afraid of them”可知，这些犬种很友好，人们不会害怕它们。故填No, because these dogs are friendly and people are not afraid of them. 29．根据“Not all dogs make good police dogs. They must be completely trustworthy and honest”可知，优秀的警犬必须完全可靠且诚实。故填They must be completely trustworthy and honest. 30．根据“This is because some dogs, such as bloodhounds, have a very good sense of smell and can be trained to recognize certain types of smells”可知，一些犬种嗅觉极佳，能被训练识别特定气味。故填Because they have a very good sense of smell and can be trained to recognize certain smells. 请根据短文内容及首字母提示，填写所缺单词。 British scientist Jane Goodall, known for her great studies of chimpanzees (黑猩猩), died on Oct 1, 2025 at the age of 91. Born in England in 1934, Goodall was so c 1 about wild animals that she always searched for the information online and she also dreamed of w 2 with them in Africa. However, her poor family couldn’t help her, so she worked to save money for her trip. In July 1960, Goodall f 3 traveled to Tanzania and entered the little-known world of wild chimpanzees. Over the next 60 years, Goodall’s findings c 4 how people understand human relationships with chimpanzees and introduced a new m 5 to study wildlife. Goodall’s research was amazing because she lived closely with wild chimpanzee groups to learn about their social lives. She even gave a n 6 to each chimp and formed close relationships with them, learning how similar they were to us. She saw that chimpanzees have different personalities (性格). Two of Goodall’s most important findings came in 1960. That year, she saw a group of chimpanzees e 7 meat, challenging the old idea that chimps only ate plants. She also saw something even more s 8 : male (雄性的) chimpanzee making and using tools. Since then, scientists have found evidence(证据) of tool use in the animal world. Besides her findings, Goodall traveled the world to speak about the d 9 situations chimpanzees are facing. “As they can’t speak for t 10 , that’s why I’m here.” Goodall told National Geographic magazine. 【答案】 1．curious/urious 2．working/orking 3．finally/inally 4．changed/hanged 5．method/ethod 6．name/ame 7．eating/ating 8．surprising/urprising 9．difficult/dangerous/ifficult/angerous 10．themselves/hemselves 【导语】本文是一篇记叙文，介绍了英国科学家简·古道尔的生平与成就。 1．句意：古道尔于 1934 年出生在英国，她对野生动物充满好奇，总是通过网络搜索相关信息，并且还梦想着能去非洲与它们一起工作。根据“about wild animals”及首字母可知，此处用be curious about表示“对……好奇”，故填curious。 2．句意：古道尔于 1934 年出生在英国，她对野生动物充满好奇，总是通过网络搜索相关信息，并且还梦想着能去非洲与它们一起工作。根据“dreamed of …with them in Africa”及首字母可知，梦想着和野生动物一起工作，work“工作”，of是介词，后接动名词，故填working。 3．句意：1960 年 7 月，古道尔终于踏上了前往坦桑尼亚的旅程，进入了鲜为人知的野生黑猩猩的世界。根据“Goodall…traveled to Tanzania and entered the little-known world of wild chimpanzees.”及首字母可知，终于踏上了前往坦桑尼亚的旅程，finally“终于”，故填finally。 4．句意：在接下来的 60 年里，古道尔的发现改变了人们对于人类与黑猩猩之间关系的理解，并开创了一种研究野生动物的新方法。根据“Goodall’s findings…how people understand human relationships with chimpanzees”及首字母可知，他的发现改变了人们对于人类与黑猩猩之间关系的理解，change“改变”，根据“introduced”可知，此空应填动词过去式，故填changed。 5．句意：在接下来的 60 年里，古道尔的发现改变了人们对于人类与黑猩猩之间关系的理解，并开创了一种研究野生动物的新方法。根据“introduced a new…to study wildlife”及首字母可知，开创了一种新方法，method“方法”，a修饰名词的单数形式，故填method。 6．句意：她甚至给每只黑猩猩都起了名字，并与它们建立了亲密的关系，从而了解到它们与我们的相似之处究竟有多少。根据“She even gave a…to each chimp”及首字母可知，给每个猩猩都起了名字，give a name to“给……起名字”，故填name。 7．句意：那一年，她目睹了一群黑猩猩在进食肉类，这打破了人们长期以来认为黑猩猩只吃植物的固有观念。根据“saw a group of chimpanzees…meat”及首字母可知，看到猩猩吃肉，eat“吃”，see sb/sth doing sth“看到某人/某物正在做某事”，故填eating。 8．句意：她还看到了一些更为令人惊讶的事情。根据“male (雄性的) chimpanzee making and using tools”及首字母可知，雄性黑猩猩制造和使用工具，这是一种令人惊讶的行为，修饰物用以ing结尾的形容词，surprising“令人惊讶的”，故填surprising。 9．句意：除了这些研究成果之外，古道尔还走遍世界各地，向人们讲述黑猩猩所面临的艰难处境。根据“speak about the…situations chimpanzees are facing”及首字母可知，讲述猩猩所面临的困难或危险处境，以此来让人们重视，difficult“困难的”，dangerous“危险的”，故填difficult/dangerous。 10．句意：因为它们无法为自己发声，所以我就站了出来。根据“As they can’t speak for”及首字母可知，猩猩无法为自己发声，此空应填反身代词themselves指代猩猩它们自己，故填themselves。 7 / 10 学科网（北京）股份有限公司 $
