After watching the show, she became more interested in dolphins and wanted to know about the animals, so she looked up more information about dolphins on the Internet. Communication (交流) Every dolphin has its own “name”. And the “name” is a special whistle (哨声). When a dolphin is born, it usually has an unusual whistle for itself. Dolphins “talk” to each other about a lot of things, such as their age, feelings, and finding food. They also use sounds and body language to communicate. Play Dolphins live in groups, and they often join others from different groups to play games and have fun, just like people. Scientists believe only smart animals can play together. Teamwork Dolphins make plans for getting things they want like people. In the seas of southern Brazil, when there are fish near a boat, dolphins make a sound to the fishermen. Then the fishermen put their nets in the water to catch fish. Why do dolphins assist the fishermen? That’s because they can eat some of the fish from the fishermen. 51．What didn’t the dolphins do during the dolphin show? A．Went through rings. B．Caught fish. C．Played with balls.

We know that dogs can help blind people go to some places. Now, horses can do it too. Digby is a small American horse. Now, it is the first guide horse in England. And its owner is a blind man named Mohammed Patel. Patel is afraid of dogs, so he chooses Digby as his guide. Digby gets a lot of training with Patel. It learns to walk slowly and lead Patel to walk on the street and get books and magazines for him. It also helps Patel choose clothes when he goes shopping. Now, it is not a small horse. It is very big and about 0.8 metres tall, so Patel can’t take it to his company (公司). When Patel takes it to the office, it knocks (碰) things off the desks. So Patel has to say goodbye to Digby. Digby is very unhappy. Luckily, Digby has a new job. It helps blind people travel around some places in London. As we know, a guide dog has only eight years of working life, but a guide horse can work for about 40 years. So a guide horse can be a “lifelong friend” for people. 55．Why does Mohammed Patel choose Digby as his “eyes”? A．Because Digby is tall. B．Because guide dogs are expensive. C．Because he is afraid of dogs. D．Because he likes horses. 56．What does the underlined word “It” in Paragraph 2 refer to? A．Patel. B．The dog. C．The place.

A service animal is an animal that is trained to do things for people who cannot do them alone because of disability. Dogs are most usually used as service animals because they are intelligent animals. They also have a good sense of smell and can sense dangerous situations. In addition, dogs are easy to train and are loyal to their owners. When in danger, dogs will do anything to keep their owners safe. Service dogs are sometimes called guide dogs or hearing dogs. These dogs can help people who cannot see or hear. They are trained to open and close a door, push a button, and listen to a command. If some people need medical attention, the dogs are trained to bark and get help. Dogs can also be used as therapy dogs. They may visit a school or hospital to help people who are feeling lonely or anxious. Therapy dogs can provide kindness and love to improve a person’s mood, which can then improve that person’s health. Although dogs are the most common service animals, there are other animals that can be trained to be service animals as well. You might see a cat, a rabbit or a horse that is used as a service animal. These animals can keep a person company and become a good friend. 59．What is the best title for this passage?

By placing tiny QR codes (代码) on the backs of the bees, the researchers can keep track of when the bees leave and return to their hives. The work will help scientists learn more about how bees collect food and how far they travel. They decided to use simple codes called “AprilTags”. These codes are easy for cameras to track and decode (解码), even when the lighting isn’t good. They are small, and can be glued (粘) onto the back of a bee without causing any harm. By placing a solar-powered camera and a tiny computer above the entrance to a hive, the researchers could track the movements of each tagged bee (贴标签的蜜蜂). They could tell when each bee left the hive and when it returned. They could also record the temperature. The new system gave the researchers a lot of information about the bees’ movements. They found that most trips outside the hive took between one and four minutes. The scientists think these short trips were used for quick jobs like checking the weather or pooping. Most trips, even longer ones, were shorter than 20 minutes. But about 34% of the bees took trips that lasted longer than two hours. The scientists say this could show that the bees were making longer trips to collect food. The researchers noticed that the bees spent more time out collecting when there were fewer flowers around. But some of these “long trips” could also be mistakes, where the camera didn’t catch the bee returning. The scientists were surprised by how long the bees lived. Before the study, scientists thought honey bees lived for about 28 days. But the tagged bees didn’t start collecting food until they were roughly two weeks old. And the researchers discovered that the bees continued to collect food for six weeks after that. Scientists know that bees use a special “waggle dance” to communicate with each other about where to collect food. Now the researchers want to see how their new tracking information matches up with these special movements. They plan to teach beekeepers and other scientists how to use their tracking system. 62．What is the main purpose of the study? A．To discover how bees build their hives. B．To stop bees from getting lost during long trips. C．To teach bees how to communicate using QR codes. D．To track bee movements and learn about their behavior. 63．The researchers use AprilTags to track the bees mainly because ________. A．they last longer than other types of tags B．they help bees communicate with each other C．they are small and easy for cameras to follow D．they cause no harm and can check the weather 64．What is one important finding of the study? A．All bees leave the hive early in the morning. B．Bees fly longer when there are more flowers. C．Bees live longer than scientists once believed. D．Bees don’t stop collecting food until 6 weeks old. 65．What makes this study meaningful? A．It shows how temperature possibly affects bee movements. B．It may help scientists better understand the “waggle dance”. C．It proves that bees are likely to use QR codes to communicate. D．It may help beekeepers earn more money from honey sales. 【答案】62．D 63．C 64．C 65．B 【导语】本文是一篇说明文，介绍了宾夕法尼亚州立大学的科学家通过在蜜蜂背上贴微型QR代码来追踪蜜蜂的活动，从而了解蜜蜂的觅食行为、飞行距离和寿命等信息，并计划将这一追踪系统推广给养蜂人和其他科学家。 62．细节理解题。根据文章第一段“The work will help scientists learn more about how bees collect food and far they travel.”可知，该研究的主要目的是追踪蜜蜂的活动并了解它们的行为。故选D。 63．细节理解题。根据文章第二段“These codes are easy for cameras to track and decode (解码), even when the lighting isn’t good. They are small, and can be glued (粘) onto the back of a bee without causing any harm.”可知，研究人员使用AprilTags追踪蜜蜂，主要是因为它们体积小，便于相机追踪。故选C。 64．细节理解题。根据文章第六段“Before the study, scientists thought honey bees lived for about 28 days. But the tagged bees didn’t start collecting food until they were roughly two weeks old. And the researchers discovered that the bees continued to collect food for six weeks after that.”可知，研究发现蜜蜂的寿命比科学家之前认为的要长。故选C。 65．推理判断题。根据文章最后一段“Scientists know that bees use a special ‘waggle dance’ to communicate with each other about where to collect food. Now the researchers want to see how their new tracking information matches up with these special movements.”可知，这项研究的意义在于它可能帮助科学家更好地理解蜜蜂的“摇摆舞”。故选B。 六、任务型阅读（每小题2分，共10分） 阅读下面短文，简略回答问题。 The Nile crocodile (鳄) lives in and near African rivers.

They are excellent swimmers. They can swim as fast as 30 km/h and stay up to 30 minutes under water. As meat eaters, the Nile crocodiles eat birds, fish and other crocodiles. Sometimes they even eat people. A person washing clothes by the river might just look like a delicious meal for them. Hundreds of people die because of them each year. Now the Nile crocodiles are in danger. Do you know why? First, people kill them for their skin (皮肤) to make things like shoes and handbags. Second, people catch them for food or medicine.

Because people kill them for their skin to make things like shoes and handbags./Because people catch them for food or medicine./Because some people destroy their home. (答案不唯一) 【导语】本文主要介绍了尼罗鳄的生存环境、寿命、食物、水下停留时长以及濒危原因 。 66．根据“The Nile crocodile (鳄) lives in and near African rivers.”可知，尼罗鳄生活在非洲河流里及河流附近，故填In and near African rivers. 67．根据“Some can even live up to 100 years old.”可知，一些尼罗鳄能活到100岁，故填100 years old. 68．根据“As meat eaters, the Nile crocodiles eat birds, fish and other crocodiles.

Once upon a time, there was a little boy named Tom who suffered from cerebral palsy. His life was filled with 42 and he could hardly move or 43 like normal (正常的) children. One day, Tom’s parents took him to a special dolphin-assisted therapy (治疗) center. The moment Tom was brought near the dolphins, something 44 happened. The dolphins seemed to 45 Tom’s condition. They swam gently around him, making 46 sounds. The trainers at the center said that the ultrasonic waves (超声波) emitted by dolphins could have a positive effect on children with cerebral palsy. These waves could stimulate (刺激、促进) the children’s nervous systems (神经系统), helping to activate dormant nerve cells. As Tom interacted with the dolphins, he showed more expressions and was more willing to move his body. During each therapy session, Tom would be accompanied by a dolphin. The dolphin would swim beside him, and sometimes even gently 47 him with its nose. Tom’s parents watched 48 as their son gradually made progress. With the help of the dolphins, Tom’s muscle (肌肉) strength improved, and he could sit up and even make some simple movements on his own.

Mary felt excited when she saw the dolphins play with balls, go through rings and dance with the trainers. After watching the show, she became more interested in dolphins and wanted to know about the animals, so she looked up more information about dolphins on the Internet. Communication (交流) Every dolphin has its own “name”. And the “name” is a special whistle (哨声). When a dolphin is born, it usually has an unusual whistle for itself. Dolphins “talk” to each other about a lot of things, such as their age, feelings, and finding food. They also use sounds and body language to communicate. Play Dolphins live in groups, and they often join others from different groups to play games and have fun, just like people. Scientists believe only smart animals can play together. Teamwork Dolphins make plans for getting things they want like people. In the seas of southern Brazil, when there are fish near a boat, dolphins make a sound to the fishermen. Then the fishermen put their nets in the water to catch fish. Why do dolphins assist the fishermen? That’s because they can eat some of the fish from the fishermen. 51．What didn’t the dolphins do during the dolphin show? A．Went through rings. B．Caught fish. C．Played with balls. D．Danced. 52．What can we infer about dolphin communication from the text? A．Dolphins only communicate about finding food. B．Dolphins can communicate by sounds but not through body language. C．They share information about personal details like age and feelings. D．All the dolphins share one name. 53．Why do scientists think dolphins are smart animals? A．Because they can perform in ocean shows. B．Because they live in large groups underwater. C．Because they can play cooperatively (合作地) with others. D．Because they communicate by using special whistles. 54．What does the underlined word “assist” mean in Paragraph 4? A．Help. B．Protect. C．Harm. D．Save. B Animals are our friends. We know that dogs can help blind people go to some places. Now, horses can do it too. Digby is a small American horse. Now, it is the first guide horse in England. And its owner is a blind man named Mohammed Patel. Patel is afraid of dogs, so he chooses Digby as his guide. Digby gets a lot of training with Patel. It learns to walk slowly and lead Patel to walk on the street and get books and magazines for him. It also helps Patel choose clothes when he goes shopping. Now, it is not a small horse. It is very big and about 0.8 metres tall, so Patel can’t take it to his company (公司). When Patel takes it to the office, it knocks (碰) things off the desks. So Patel has to say goodbye to Digby. Digby is very unhappy. Luckily, Digby has a new job. It helps blind people travel around some places in London. As we know, a guide dog has only eight years of working life, but a guide horse can work for about 40 years. So a guide horse can be a “lifelong friend” for people. 55．Why does Mohammed Patel choose Digby as his “eyes”? A．Because Digby is tall. B．Because guide dogs are expensive. C．Because he is afraid of dogs. D．Because he likes horses. 56．What does the underlined word “It” in Paragraph 2 refer to? A．Patel. B．The dog. C．The place. D．Digby. 57．How does Digby feel when he has to leave Patel? A．Sad. B．Lucky. C．Excited. D．Angry. 58．What’s the passage mainly about? A．It is about a guide horse—Digby. B．It is about a blind man—Patel. C．It is about Digby’s new job. D．It is about a guide dog’s working life. C Have you ever seen a blind person on the bus with a dog? This dog is most likely a service animal. A service animal is an animal that is trained to do things for people who cannot do them alone because of disability.

Once upon a time, there was a little boy named Tom who suffered from cerebral palsy. His life was filled with 42 and he could hardly move or 43 like normal (正常的) children. One day, Tom’s parents took him to a special dolphin-assisted therapy (治疗) center. The moment Tom was brought near the dolphins, something 44 happened. The dolphins seemed to 45 Tom’s condition. They swam gently around him, making 46 sounds. The trainers at the center said that the ultrasonic waves (超声波) emitted by dolphins could have a positive effect on children with cerebral palsy. These waves could stimulate (刺激、促进) the children’s nervous systems (神经系统), helping to activate dormant nerve cells. As Tom interacted with the dolphins, he showed more expressions and was more willing to move his body. During each therapy session, Tom would be accompanied by a dolphin. The dolphin would swim beside him, and sometimes even gently 47 him with its nose. Tom’s parents watched 48 as their son gradually made progress.

Mary felt excited when she saw the dolphins play with balls, go through rings and dance with the trainers. After watching the show, she became more interested in dolphins and wanted to know about the animals, so she looked up more information about dolphins on the Internet. Communication (交流) Every dolphin has its own “name”. And the “name” is a special whistle (哨声). When a dolphin is born, it usually has an unusual whistle for itself. Dolphins “talk” to each other about a lot of things, such as their age, feelings, and finding food. They also use sounds and body language to communicate. Play Dolphins live in groups, and they often join others from different groups to play games and have fun, just like people. Scientists believe only smart animals can play together. Teamwork Dolphins make plans for getting things they want like people. In the seas of southern Brazil, when there are fish near a boat, dolphins make a sound to the fishermen. Then the fishermen put their nets in the water to catch fish. Why do dolphins assist the fishermen? That’s because they can eat some of the fish from the fishermen. 51．What didn’t the dolphins do during the dolphin show? A．Went through rings. B．Caught fish. C．Played with balls. D．Danced. 52．What can we infer about dolphin communication from the text? A．Dolphins only communicate about finding food. B．Dolphins can communicate by sounds but not through body language. C．They share information about personal details like age and feelings. D．All the dolphins share one name. 53．Why do scientists think dolphins are smart animals? A．Because they can perform in ocean shows. B．Because they live in large groups underwater. C．Because they can play cooperatively (合作地) with others. D．Because they communicate by using special whistles. 54．What does the underlined word “assist” mean in Paragraph 4? A．Help. B．Protect. C．Harm. D．Save. B Animals are our friends. We know that dogs can help blind people go to some places. Now, horses can do it too. Digby is a small American horse. Now, it is the first guide horse in England. And its owner is a blind man named Mohammed Patel. Patel is afraid of dogs, so he chooses Digby as his guide. Digby gets a lot of training with Patel. It learns to walk slowly and lead Patel to walk on the street and get books and magazines for him. It also helps Patel choose clothes when he goes shopping. Now, it is not a small horse. It is very big and about 0.8 metres tall, so Patel can’t take it to his company (公司). When Patel takes it to the office, it knocks (碰) things off the desks. So Patel has to say goodbye to Digby. Digby is very unhappy. Luckily, Digby has a new job. It helps blind people travel around some places in London. As we know, a guide dog has only eight years of working life, but a guide horse can work for about 40 years. So a guide horse can be a “lifelong friend” for people. 55．Why does Mohammed Patel choose Digby as his “eyes”? A．Because Digby is tall. B．Because guide dogs are expensive. C．Because he is afraid of dogs. D．Because he likes horses. 56．What does the underlined word “It” in Paragraph 2 refer to? A．Patel. B．The dog. C．The place. D．Digby. 57．How does Digby feel when he has to leave Patel? A．Sad. B．Lucky. C．Excited. D．Angry. 58．What’s the passage mainly about? A．It is about a guide horse—Digby. B．It is about a blind man—Patel. C．It is about Digby’s new job. D．It is about a guide dog’s working life. C Have you ever seen a blind person on the bus with a dog? This dog is most likely a service animal. A service animal is an animal that is trained to do things for people who cannot do them alone because of disability. Dogs are most usually used as service animals because they are intelligent animals. They also have a good sense of smell and can sense dangerous situations. In addition, dogs are easy to train and are loyal to their owners. When in danger, dogs will do anything to keep their owners safe. Service dogs are sometimes called guide dogs or hearing dogs. These dogs can help people who cannot see or hear. They are trained to open and close a door, push a button, and listen to a command. If some people need medical attention, the dogs are trained to bark and get help. Dogs can also be used as therapy dogs. They may visit a school or hospital to help people who are feeling lonely or anxious. Therapy dogs can provide kindness and love to improve a person’s mood, which can then improve that person’s health. Although dogs are the most common service animals, there are other animals that can be trained to be service animals as well. You might see a cat, a rabbit or a horse that is used as a service animal. These animals can keep a person company and become a good friend. 59．What is the best title for this passage? A．How to improve health B．Animals that people can keep C．How to train dogs D．Service animals that help people 60．What do therapy dogs do? A．They are trained to bark and get help. B．They make people feel happier. C．They make people feel tired. D．They can help with all the health problems. 61．Which of the following is true? A．Animals cannot be used to do jobs for people. B．Dogs are more difficult to train than cats. C．Dogs can help improve people’s health by making them feel happy. D．Other animals cannot be used as service animals because they are not smart. D Scientists at Penn State University used an unusual method to track honey bees. By placing tiny QR codes (代码) on the backs of the bees, the researchers can keep track of when the bees leave and return to their hives. The work will help scientists learn more about how bees collect food and how far they travel. They decided to use simple codes called “AprilTags”. These codes are easy for cameras to track and decode (解码), even when the lighting isn’t good. They are small, and can be glued (粘) onto the back of a bee without causing any harm. By placing a solar-powered camera and a tiny computer above the entrance to a hive, the researchers could track the movements of each tagged bee (贴标签的蜜蜂). They could tell when each bee left the hive and when it returned. They could also record the temperature. The new system gave the researchers a lot of information about the bees’ movements. They found that most trips outside the hive took between one and four minutes. The scientists think these short trips were used for quick jobs like checking the weather or pooping. Most trips, even longer ones, were shorter than 20 minutes. But about 34% of the bees took trips that lasted longer than two hours. The scientists say this could show that the bees were making longer trips to collect food. The researchers noticed that the bees spent more time out collecting when there were fewer flowers around. But some of these “long trips” could also be mistakes, where the camera didn’t catch the bee returning. The scientists were surprised by how long the bees lived. Before the study, scientists thought honey bees lived for about 28 days. But the tagged bees didn’t start collecting food until they were roughly two weeks old. And the researchers discovered that the bees continued to collect food for six weeks after that. Scientists know that bees use a special “waggle dance” to communicate with each other about where to collect food. Now the researchers want to see how their new tracking information matches up with these special movements. They plan to teach beekeepers and other scientists how to use their tracking system. 62．What is the main purpose of the study? A．To discover how bees build their hives. B．To stop bees from getting lost during long trips. C．To teach bees how to communicate using QR codes. D．To track bee movements and learn about their behavior. 63．The researchers use AprilTags to track the bees mainly because ________. A．they last longer than other types of tags B．they help bees communicate with each other C．they are small and easy for cameras to follow D．they cause no harm and can check the weather 64．What is one important finding of the study? A．All bees leave the hive early in the morning. B．Bees fly longer when there are more flowers. C．Bees live longer than scientists once believed. D．Bees don’t stop collecting food until 6 weeks old. 65．What makes this study meaningful? A．It shows how temperature possibly affects bee movements. B．It may help scientists better understand the “waggle dance”. C．It proves that bees are likely to use QR codes to communicate. D．It may help beekeepers earn more money from honey sales. 六、任务型阅读（每小题2分，共10分） 阅读下面短文，简略回答问题。 The Nile crocodile (鳄) lives in and near African rivers. It is a very large animal. It can grow up to 6 meters long. Its body is green and brown and it has a very big mouth. Most of the Nile crocodiles can live to be about 70 years old in the wild. Some can even live up to 100 years old. The Nile crocodiles spend most of the day on the bank (岸边) of the river in the sun without moving. At night, they go back into the water to find food. They are excellent swimmers. They can swim as fast as 30 km/h and stay up to 30 minutes under water. As meat eaters, the Nile crocodiles eat birds, fish and other crocodiles. Sometimes they even eat people. A person washing clothes by the river might just look like a delicious meal for them. Hundreds of people die because of them each year. Now the Nile crocodiles are in danger. Do you know why? First, people kill them for their skin (皮肤) to make things like shoes and handbags. Second, people catch them for food or medicine. Last but not least, some people destroy their home, so the Nile crocodiles don’t have enough space to live. 66．Where do the Nile crocodiles live? 67．How old can some of the Nile crocodiles live to be? 68．What do the Nile crocodiles feed on? 69．How long can the Nile crocodiles stay under water? 70．Do you know why the Nile crocodiles are in danger? Please list one reason. 七、书面表达（共10分） 71．动物是人类最好的伙伴。 请你以 “My Favourite Animal” 为题，写一篇不少于60词的英语短文，介绍自己最喜欢的动物，并说明原因。 内容提示： 1. What animal do you like best? 2.
