They’re in fact sharks, and they’re the largest fish in the sea. 1 That’s because their sizes and their eating habits are like some whales. Whale sharks are really big. Most of them grow to about 12 meters. That’s about the size of a yellow school bus. 2 These big fish are easy to find. That’s because they have white spots (斑点) and lines on their gray bodies. Those are special to each whale shark. Why? 3 Whale sharks have more than 3,000 teeth in their mouths. However, their teeth are not big or really sharp (锋利的) like the teeth of other sharks. That’s because they don’t use them to chew (咀嚼) food. 4 The large fish swim with their mouths open. That moves water over the filters (滤食器) in their mouths. These filters can help them catch small plants and animals called plankton (浮游生物) in the water. Whale sharks eat a lot of plankton. 5 . Whale sharks like living in areas with warm water. You can even swim with them because they aren’t dangerous to people. Just remember not to get too close to them. A．Why are they called whale sharks? B．Because no whale sharks have the same spots and lines. C．They feed themselves in a different way. D．Some whale sharks can even grow to about 18 meters. E．They sometimes also eat small fish. Bees are amazing animals that not only make delicious honey but also help humans in many ways in our world. Do you know that there are around 20,000 kinds of bees worldwide? 1 Without bees, we wouldn’t have any food! When bees fly around, they carry pollen from one plant to another, helping the new plants to grow. 2 They can also help fruits and vegetables grow. 3 They’re losing their living places because the places they live are disappearing. Also, they are not feeling well because of chemicals on plants, and the changing weather is making life harder for them. As we know, bees live in houses that we call hives (蜂巢) . There are three kinds of bees, worker bees, drones (雄蜂) , and queen bees. 4 Drones, on the other hand, don’t work. Before winter arrives, drones are either killed or driven away from the hive. The queen bee is the most important, being the largest andthe only one that can lay eggs in the hive. 5 The queen bee lays lots of eggs, up to 800,000 in her life. But with the help of these clever robot bees, she can lay even more eggs, making sure a larger number of bees do their important jobs. 根据材料内容，从下面五个选项中选出能填入文中空缺处的最佳选项，使文章意思通顺、内容完整。 A．Bees can help flowers come out. B．However, bees are facing serious problems. C．To help bees, scientists made robot bees to help the queen bee. D．Each year on May 20th, we celebrate World Bee Day to thank bees. E．Worker bees are hard-working all year round, serving their queen busily. Many animals are disappearing from our world. Some, like the great auk (大海雀), have already died out. Others, such as orangutans (红毛猩猩) and hedgehogs (刺猬) are in great danger now. 1 The great auk was a large bird that could not fly. People hunted it for its meat and feathers until the last one died in 1844. 2 Today, animals are facing even more problems. For example, people are cutting down forests, polluting the water and land, and causing climate change. 3 In fact, over a million species are in danger. The number of hedgehogs is falling quickly because cities are growing larger and farmers use chemicals that can kill them. 4 In 2022, many countries all over the world made an important plan to protect 30% of the planet by 2030. For example, in Indonesia, a dentist named Hotlin Ompusunggu has a special program. She offers cheaper dental care to people who help protect the forests where orangutans live. 5 We must all take action before it is too late. A．Why are these animals disappearing? B．These activities are harming both animals and plants. C．However, people are also trying to solve these problems. D．This way, she encourages locals to save these lovely animals. E．This was a very early example of how humans could cause an animal to die out. The Arctic fox (北极狐) is a kind of small fox. 1 It grows about 50 centimeters long, not including its tail, 30 centimeters tall and weighs from 3 to 7 kilos. 2 The white ones are white in winter, but gray-brown in summer. The blue ones are blue-gray all year round. The Arctic foxes have long, thick hair that is called fur (毛皮) 3 The Arctic foxes mainly feed on birds, birds’ eggs and other small animals. Teamwork is the way they look for food. 4 Baby Arctic foxes are very lovely. 5 For the first half of the year, their parents offer them food. They begin to look for food on their own when they are about six months old. The next year they can live alone. Today, the number of the Arctic foxes is becoming smaller and smaller, because people kill them for their fur to make beautiful coats for money. Something must be done to protect the Arctic foxes. 根据短文内容，从下面五个选项中选出能填入文中空缺处的最佳选项。 A．It lives in the Arctic. B．They don’t like to look for food alone. C．The Arctic foxes are white or blue in color.

Penguins are popular in zoos and they always attract (吸引) many tourists from different places. There are many different kinds of penguins. The emperor penguin is the largest, standing up to 1.2 m tall and weighing up to 45 kg. 2 It is only about 30 cm tall and weighs only about 1 kg. Penguins are birds, but they can’t fly. However, they are able to swim. 3 Penguins live in cold environments. Their thick fat and waterproof feathers (防水羽毛) can keep them warm in freezing temperatures. 4 There, they have to adapt (适应) to the natural conditions. But in zoos with a carefully controlled environment, they are able to live up to 30 years. However, penguins are in danger now. There are fewer and fewer of them. 5 Other reasons include food shortages and environmental problems like oil pollution. To protect penguins, many people make sweaters for them.

Their numbers have dropped by over 60% in the last 40 years. Scientists wanted to study the seafloor to learn more about how sea lions use different areas of the seafloor to gather food. 1 Underwater robots are expensive. They often move slowly, and they can’t go everywhere. So scientists came up with a good idea—attaching (固定) cameras to sea lions. The sea lions could cover large areas of the seafloor quickly, and go deep into places that humans can’t reach. The scientists chose 8 healthy adult female (雌性) sea lions from two different groups. They chose females because they would soon return to land to feed their babies. 2 After finishing their activities in the deep sea, the sea lions would return to the seashore to rest. 3 The videos recorded the seafloor in places that had never been seen before. The scientists were able to know about 6 different types of seafloor environments. Using the information from the videos, the scientists developed a special tool. 4 The scientists now can use the tool to predict exactly what the seafloor is like, even in areas that haven’t been studied. Thanks to the sea lions, the scientists now have a better idea about the kinds of areas used by these endangered animals and where these areas can be found. As one of the researchers said, “ 5 ” A．But studying the seafloor is difficult. B．This tool can “guess” what the seafloor is like. C．The videos showed different kinds of sea lions. D．They are expected to collect 89 hours of videos. E．That meant the scientists could easily get the cameras back. F．They give us a window into the world that we haven’t seen before. Elephant Families African elephants live together in a herd (群). They all take care of each other. The leader of the herd is an old mother elephant. She is the matriarch (女酋长). 1 They follow the matriarch because she guards the family from danger. Adult male elephants go off to live on their own and start families. 2 Young elephants learn by copying other elephants. Elephants live to be 50 or 60 years old. They have long memories. A matriarch can remember where to find water even in a dry period. The herd will follow her there. 3 Elephants talk to each other with low rumbling (隆隆的) sounds. Some rumbling sounds are so deep that people cannot hear them. 4 So they greet each other by touch. They use their trunks (象鼻) and feet. If danger comes, mothers flap their ears to call their babies. The adult elephants circle around the babies. Other animals do not often attack elephants. But a lion might try to attack a sick elephant or a baby. If this happens, the elephants make loud sounds. 5 The matriarch puts herself in front of the herd. She flaps her ears out wide. This makes her look even larger. Then she lowers her head and charges the enemy in a big cloud of dust. 根据短文内容，从选项中选出能填入文中空白处的最佳选项，选项中有一项为多余选项。 A．Elephants are intelligent animals. B．They also hit the ground with their trunks.

A leopard’s body is built for hunting (狩猎). It has a powerful body and can run at speeds of up to 57 kilometers per hour. It is also an excellent swimmer and climber and can jump far. 1 This helps it keep balanced (平衡) and lets it turn quickly. 2 Each of them has its own area where it lives and, although it often shares parts of it, it tries to avoid others. Their hunting and feeding habits are also quite unique. They often pull their food up into the trees so that they can keep it safe. A leopard will often leave its food up in the tree for days and return only when it’s hungry! Mother leopards give birth to two or three little leopard at a time. The mother leopard takes great care of her cubs, teaching them essential hunting and survival skills as they grow. 3 Some people believe that the bones and whiskers (细须) of leopards can make sick people get better. Many leopards are killed each year for their fur and other body parts. 4 To save leopards, we need to take action. Governments need to make and carry out laws and stop illegal animal trading. Setting up more protected areas is a must to keep leopards safe. These protected areas can provide a safe haven for leopards to live and breed. 5 When they know leopards are important for the ecosystem, they’ll support protection. Only by working together can we make sure these wonderful leopards can survive and thrive. A．Adult leopards live alone. B．Educating local people is also important. C．Leopard’s tail is just about as long as its entire body. D．This is one reason why the leopard is an endangered animal. E．They were found in the wild in many areas around the world. F．By the time they are two years old they will be able to live on their own. 请认真阅读下面短文，从短文后所给的六个选项中选出五个可以填入空白处的最佳选项。 Wildlife workers in Florida are feeding manatees (海牛) to keep them from starving. 1 So far, the rescue workers have already given out tons of lettuce. Manatees are huge sea mammals that can be as long as 4 metres when they are mature. 2 In spite of their size, manatees only eat plants that live in the sea. That’s one reason why they’re sometimes called “sea cows”. They spend most of their time in warm and shallow water looking for food. But Florida’s manatees have been on the US government’s list of endangered animals since 1967. Most threats to manatees come from humans. One of the biggest problems facing the creatures is boats. Manatees are curious and fairly slow, which has led to thousands of manatees being injured or killed. 3 At one point, there were only about 2,000 manatees left in Florida. But by 2016, there were roughly 8,800 manatees. But now manatees are facing a new challenge: They can’t get enough to eat. Many of the beds of seagrass that manatees depend upon have been killed by man-caused pollution. Seagrass began to disappear around 2011. Warming seas with polluted water have allowed the growth of a great amount of algae (海藻) on the ocean’s surface. 4 In 2021, more than one thousand manatees died from starving. 5 Many of the manatees that remain are so thin that their ribs can be seen. Often they have trouble swimming. So in December 2021, wildlife experts came up with a plan to get emergency food for the manatees. They decided to feed them green vegetables like lettuce and cabbage. Now Florida is working to help restore seagrass beds. But that will take time. A．That was a record. B．They can weigh up to 590 kilograms. C．The feeding station has been very successful. D．With protection, the number of manatees managed to bounce (弹起) back. E．It blocks (挡住) the sunlight that helps the seagrass to grow. F．But feeding these massive sea creatures takes a lot of food. 学科网（北京）股份有限公司 $ Unit 5 Saving animals in danger 阅读还原10篇 内容导航 单元话题 基础语篇练习 重难语篇练习 单元话题聚焦 动物保护 基础语篇练习 稳扎稳打 必拿分数：聚焦稳拿分数题目，确保基础分值 重难语篇练习 突破瓶颈 争夺高分：聚焦高难度题目，争夺关键分数 基础语篇练习 根据短文内容，从下列选项中选出能填入文中空白处的最佳选项。 The African elephant is the biggest land animal in the world.

Their numbers have dropped by over 60% in the last 40 years. Scientists wanted to study the seafloor to learn more about how sea lions use different areas of the seafloor to gather food. 1 Underwater robots are expensive. They often move slowly, and they can’t go everywhere. So scientists came up with a good idea—attaching (固定) cameras to sea lions. The sea lions could cover large areas of the seafloor quickly, and go deep into places that humans can’t reach. The scientists chose 8 healthy adult female (雌性) sea lions from two different groups. They chose females because they would soon return to land to feed their babies. 2 After finishing their activities in the deep sea, the sea lions would return to the seashore to rest. 3 The videos recorded the seafloor in places that had never been seen before. The scientists were able to know about 6 different types of seafloor environments. Using the information from the videos, the scientists developed a special tool. 4 The scientists now can use the tool to predict exactly what the seafloor is like, even in areas that haven’t been studied. Thanks to the sea lions, the scientists now have a better idea about the kinds of areas used by these endangered animals and where these areas can be found. As one of the researchers said, “ 5 ” A．But studying the seafloor is difficult. B．This tool can “guess” what the seafloor is like. C．The videos showed different kinds of sea lions. D．They are expected to collect 89 hours of videos. E．That meant the scientists could easily get the cameras back. F．They give us a window into the world that we haven’t seen before. 【答案】1．A 2．E 3．D 4．B 5．F 【导语】本文是一篇说明文，主要讲了科学家为研究濒危澳大利亚海狮的觅食海底区域，将相机固定在雌性海狮身上收集视频，据此研发预测海底环境的工具，进而更深入了解海狮的活动区域。 1．根据“Underwater robots are expensive.

They all take care of each other. The leader of the herd is an old mother elephant. She is the matriarch (女酋长). 1 They follow the matriarch because she guards the family from danger. Adult male elephants go off to live on their own and start families. 2 Young elephants learn by copying other elephants. Elephants live to be 50 or 60 years old. They have long memories. A matriarch can remember where to find water even in a dry period. The herd will follow her there. 3 Elephants talk to each other with low rumbling (隆隆的) sounds. Some rumbling sounds are so deep that people cannot hear them. 4 So they greet each other by touch. They use their trunks (象鼻) and feet. If danger comes, mothers flap their ears to call their babies. The adult elephants circle around the babies. Other animals do not often attack elephants. But a lion might try to attack a sick elephant or a baby. If this happens, the elephants make loud sounds. 5 The matriarch puts herself in front of the herd. She flaps her ears out wide. This makes her look even larger. Then she lowers her head and charges the enemy in a big cloud of dust. 根据短文内容，从选项中选出能填入文中空白处的最佳选项，选项中有一项为多余选项。 A．Elephants are intelligent animals. B．They also hit the ground with their trunks.

A leopard’s body is built for hunting (狩猎). It has a powerful body and can run at speeds of up to 57 kilometers per hour. It is also an excellent swimmer and climber and can jump far. 1 This helps it keep balanced (平衡) and lets it turn quickly. 2 Each of them has its own area where it lives and, although it often shares parts of it, it tries to avoid others. Their hunting and feeding habits are also quite unique. They often pull their food up into the trees so that they can keep it safe. A leopard will often leave its food up in the tree for days and return only when it’s hungry! Mother leopards give birth to two or three little leopard at a time. The mother leopard takes great care of her cubs, teaching them essential hunting and survival skills as they grow. 3 Some people believe that the bones and whiskers (细须) of leopards can make sick people get better. Many leopards are killed each year for their fur and other body parts. 4 To save leopards, we need to take action. Governments need to make and carry out laws and stop illegal animal trading. Setting up more protected areas is a must to keep leopards safe. These protected areas can provide a safe haven for leopards to live and breed. 5 When they know leopards are important for the ecosystem, they’ll support protection. Only by working together can we make sure these wonderful leopards can survive and thrive. A．Adult leopards live alone. B．Educating local people is also important. C．Leopard’s tail is just about as long as its entire body. D．This is one reason why the leopard is an endangered animal. E．They were found in the wild in many areas around the world. F．By the time they are two years old they will be able to live on their own. 【答案】1．C 2．A 3．F 4．D 5．B 【导语】本文主要介绍了非洲豹的生理特征、生活习性、繁殖方式以及它们面临的生存威胁，并提出了保护措施。 1．根据下文“This helps it keep balanced (平衡) and lets it turn quickly.”可知，此处与非洲豹身体特征相关，选项C“非洲豹的尾巴几乎和它的整个身体一样长。”符合语境。故选C。 2．根据下文“Each of them has its own area where it lives”可知，每只非洲豹都有自己的生活区域，选项A“成年非洲豹独居。”符合语境。故选A。 3．根据上文“Mother leopards give birth to two or three little leopard at a time.

Manatees are huge sea mammals that can be as long as 4 metres when they are mature. 2 In spite of their size, manatees only eat plants that live in the sea. That’s one reason why they’re sometimes called “sea cows”. They spend most of their time in warm and shallow water looking for food. But Florida’s manatees have been on the US government’s list of endangered animals since 1967. Most threats to manatees come from humans. One of the biggest problems facing the creatures is boats. Manatees are curious and fairly slow, which has led to thousands of manatees being injured or killed. 3 At one point, there were only about 2,000 manatees left in Florida. But by 2016, there were roughly 8,800 manatees. But now manatees are facing a new challenge: They can’t get enough to eat. Many of the beds of seagrass that manatees depend upon have been killed by man-caused pollution. Seagrass began to disappear around 2011. Warming seas with polluted water have allowed the growth of a great amount of algae (海藻) on the ocean’s surface. 4 In 2021, more than one thousand manatees died from starving. 5 Many of the manatees that remain are so thin that their ribs can be seen. Often they have trouble swimming. So in December 2021, wildlife experts came up with a plan to get emergency food for the manatees. They decided to feed them green vegetables like lettuce and cabbage. Now Florida is working to help restore seagrass beds. But that will take time. A．That was a record. B．They can weigh up to 590 kilograms. C．The feeding station has been very successful. D．With protection, the number of manatees managed to bounce (弹起) back. E．It blocks (挡住) the sunlight that helps the seagrass to grow. F．But feeding these massive sea creatures takes a lot of food. 【答案】1．F 2．B 3．D 4．E 5．A 【导语】本文主要讲述了佛罗里达的海牛面临生存危机，野生动物工作者采取措施救助它们的情况。 1．根据“Wildlife workers in Florida are feeding manatees to keep them from starving.”以及“So far, the rescue workers have already given out tons of lettuce.”可知，佛罗里达的野生动物工作者在给海牛喂食以防止它们饿死，且已经分发了大量的生菜，说明给这些海牛喂食需要很多食物。选项F“但是喂养这些巨大的海洋生物需要大量的食物”符合语境。故选F。 2．根据“Manatees are huge sea mammals that can be as long as 4 metres when they are mature.”可知，这里在描述海牛的体型巨大，后面应该继续介绍海牛在体型方面的特征。选项B“它们可以重达590公斤”符合语境。故选B。 3．根据“At one point, there were only about 2,000 manatees left in Florida. But by 36, there were roughly 8,800 manatees.”可知，海牛的数量从曾经的2000只左右增加到了36年的约8800只，说明在保护措施下，海牛的数量有所回升。选项D“在保护下，海牛的数量成功反弹”符合语境。故选D。 4．根据“Warming seas with polluted water have allowed the growth of a great amount of algae on the ocean’s surface.”可知，海水变暖和水污染导致海洋表面大量藻类生长，这会对海草的生长产生影响。选项E“它挡住了帮助海草生长的阳光”符合语境。故选E。 5．根据“In 2021, more than one thousand manatees died from starving.”可知，2021年有超过一千只海牛死于饥饿，这是一个比较严重的情况。选项A“那是一个记录”符合语境。故选A。 学科网（北京）股份有限公司 $
