Beside him sat a suitcase filled with watch parts. Although it was 21 , he completely focused on repairing something small. Moved by this, Margaret 22 him a piece of bread. “Sir, please eat something to warm yourself.” The old man looked up 23 . “Thank you, young lady,” he said. From then on, Margaret brought him food every day. One day, they began to talk. His name was Henry, once a watchmaker. He 24 he was working on a new escapement mechanism (擒纵装置) for watches to work more accurately (精准地). One day, Margaret found Henry was 25 . She spent all her savings to get him medical help. A few weeks later, Henry was better and finally completed his 26 . Months later, Henry took his design to the local largest watch factory. They 27 the mechanism and were shocked. Henry earned a lot of money from his invention. He came to find Margaret. “All of this began with 28 ,” he said. She refused any money. 29 Henry used the money to start a school— 30 training and modern watchmaking skills for poor people. Margaret became his student. Two years later, Margaret became a 31 and she opened a shop with only women workers. In 1890, Henry passed away. He left behind $100,000 and a letter. “Dear Margaret, you gave me the 32 to keep creating. Use this money to 33 someone’s world.

But actually, an electric motor is simply a metal bar that spins (旋转) by electricity — just like an electric fan turning around and around. Here’s how to create your own electric motor: What You Need a round magnet a 1.5-volt battery a flat-head metal screw a piece of copper wire What You Do 1. Set the flat head of the metal screw on the top of the magnet. 2. Move the positive end of the battery close to the tip of the screw. 3. Hold one end of the copper wire to the negative end of the battery. Touch the other end of the wire to the magnet. 4. Watch what happens to the screw! 36.What do we need to create the electric motor? A.A flat magnet. B.A 15-volt battery. C.A piece of copper wire. D.A round-head metal screw. 37.Which part of the screw should be placed on the magnet? A.The tip. B.The head. C.The end. D.The middle. 38.What does the copper wire connect according to the picture? A.The metal screw and the round magnet. B.The battery’s positive end and the screw. C.The battery’s negative end and the magnet. D.The magnet and the battery’s positive end. 39.What will happen after all the steps? A.It will turn. B.It will light. C.It will heat. D.It will stick. 40.Where does the text probably come from? A.108 Stories. B.The Travel Book. C.Biology Fact. D.Super Simple Science. B In a field in England, three little robots have been given a great job: to find and kill grass before planting seeds in the soil. The robots are named Tom, Dick and Harry. Tom is the first of the three clever robots to start working. He watches the crops carefully and collects the information about each plant. He can create a short introduction to each plant and even make decisions on what chemicals (化学药品) are needed for your crops. Dick does the dirty work. He can go to each plant that is doing bad to the crops and take it out. Plants that are good for the crops are left. He can spray (喷洒) things like chemicals in order to keep plants healthy. Harry is a planter. He digs holes into the ground and puts seeds into the ground, and records where he puts them. If a seed doesn’t grow, he can easily travel there and plant a new seed. The smart robots are made by Small Robot. The British company says farmers could reduce costs by 40% and chemical usage by up to 95%. The little robots allow farmers to free their soils from chemicals. Using fewer chemicals is going to conserve much money and is good for the environment. As well as reducing the use of chemicals, robots will bring us better soil quality and more plants and animals. “We have to change farming now, or else there won’t be anything to farm,” says Small Robot. 41.We can know the three robots from Paragraph 1. A.are huge B.work in a field C.can plant grass D.come from America 42.The underlined word “conserve” probably means “” in the passage. A.save B.manage C.divide D.punish 43.Which of the following is TRUE according to the passage? A.Small Robot is a British company. B.Dick’s job is to dig holes and plant seeds. C.Tom can decide what weather crops need. D.Harry never plants new seeds when they don’t grow. 44.What is the best title for the passage? A.The History of Robots B.A British Company’s New Business C.Three Smart Robots Changing Farming D.How to Reduce Chemical Usage in Fields C ①Even though the world has made great efforts to protect African elephants, many of them are still being killed for their ivory. At the end of the 1970s, over 1.3 million elephants walked around Africa. But today, their numbers have fallen to around 450,000. This is mainly caused by illegal (非法的) hunting (狩猎) for ivory. Need for ivory in markets, especially in Asia and Africa, continues to push the illegal trade (贸易). This has resulted in the deaths of at least 20,000 African elephants each year. ② Ivory, also known as “white gold”, has long been regarded as precious. Because of its unusual look, people often use it to make expensive things, such as jewellery (珠宝), musical instruments and art. And the ivory material itself can stand the test of time. That’s why many people are willing to pay high prices for ivory products. ③ However, no matter how much real ivory is sold, it’s certainly not worth the harm to elephants. So some scientists are working hard on creating the same beauty of ivory with no killing. ④ Thadd a Rath and her team at the University of Vienna have created the man-made ivory called “Digory”. It is made from synthetic resin (合成树脂) and calcium phosphate particles (磷酸钙颗粒). First, they use a 3D printer (打印机) to make the shape. Then they color-match and stain (着色) it. Finally, they polish (抛光) it to make it look like real natural ivory. Although the chemical structure (化学结构) of Digory is completely different from that of the natural ivory, it looks so real that it is hard to tell the difference by eye. ⑤ Fritz Vollrath, a biologist (生物学家) from the UK, felt excited about the invention for the fact that Digory could save many elephants from risks. He said, “We hope that, by doing more research, Digory will soon be accepted and used worldwide. And I believe that technology like this will play an important role in wildlife protection.” 45.Why does the writer list some numbers in Paragraph 1? A.To present the number of elephants in Africa. B.To introduce the ivory markets in Asia and Africa. C.To explain the reasons for the illegal trade of ivory. D.To show the dangerous situation of African elephants. 46.What does the underlined word “precious” in Paragraph 2 mean? A.Modern. B.Valuable C.Beautiful. D.Traditional 47.What do we know about Digory from Paragraph 4? a. Why Digory is invented. b. How Digory is made. c. What Digory is made from. d. Whether Digory looks real. A.abc B.acd C.bcd D.abd 48.Which of the following does Fritz Vollrath agree with? A.Digory will save all the elephants from risks. B.It’s hard for the world to accept man-made ivory. C.It will take long to make Digory used worldwide. D.Technology will support the protection of wildlife. 49.Which is the RIGHT structure of the passage? A.①/②/③/④/⑤ B.①/②③④/⑤ C.①②③④/⑤ D.①/②/③④/⑤ D What Makes an Idea Powerful? Have you ever wondered why some ideas change the world while others disappear quickly? Scientists and thinkers have studied this question for a long time. They have discovered that powerful ideas share some common features. First, powerful ideas solve a real problem. Thomas Edison didn’t just invent the light bulb for fun. He wanted to solve the problem of darkness. Before the light bulb, people used candles and oil lamps, which were dangerous and gave little light. Edison’s idea met a real need, which is why it became so successful. Similarly, the Wright brothers built the first airplane because people wanted to travel faster and further. Second, powerful ideas come to life through hard work and persistence. Many inventors fail hundreds of times before they succeed. Edison famously said, “I have not failed. I’ve just found 10,000 ways that won’t work.” This shows that great ideas don’t come easily. The key is to keep trying and learn from each failure. Third, powerful ideas are shared with others. An idea that stays in someone’s mind can never change the world. That’s why inventors and thinkers often write books, give lectures, and work with teams to spread their ideas. For example, the Internet started as a small idea in one research lab but grew into a global system because thousands of people shared and developed it together. Fourth, powerful ideas often come from curiosity. People who are curious ask questions like “Why is this the way it is?” or “Is there a better way?” These questions open the door to new possibilities. Many of the most important inventions in history were created by curious people who never stopped asking questions. Finally, powerful ideas are often simple but profound. They don’t need to be complicated to be effective. The idea that everyone should be able to read and write, for example, has changed countless lives. 50.According to the passage, why did Thomas Edison invent the light bulb? A.Because he wanted to become famous. B.Because he wanted to solve the problem of darkness. C.Because he needed a new project. D.Because he wanted to prove he was smart. 51.What does Edison’s quote “I have not failed. I’ve just found 10,000 ways that won’t work.” teach us? A.Failure is shameful. B.Great ideas come easily. C.We should give up when things get hard. D.Failure is part of the learning process. 52.According to the passage, why is it important to share ideas? A.Because ideas can only change the world when shared. B.Because sharing ideas makes people famous. C.Because everyone should have the same ideas. D.Because it is easy to share ideas. 53.What does the underlined word “profound” in the last paragraph most probably mean? A.Simple and easy. B.Deep and meaningful. C.Long and complicated. D.Boring and useless. 54.What is the main purpose of this passage? A.To explain what makes an idea powerful. B.To describe different types of inventions. C.To compare famous inventors. D.To encourage people to become inventors. E 根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 Life today would be quite different without refrigerators. How did people keep their food fresh before these machines were around? The first electric refrigerator was made in 1913. 55 In cold areas, ancient people could freeze (冷冻) their food. They could then store it in ice and snow. Warmer places allowed for drying food in sunlight. One advanced method of food storage appeared in Persia around 400 BCE. People there stored food in buildings called Yakhchal. They were made from mud (泥) brick to keep ice frozen during even the warmest summer months. During the Middle Ages, people preserved meat by salting or smoking it. They would also dry many foods, including grains. Vegetables were often salted. Many fruits were dried or turned into preserves. These foods could then be stored in cool places. 56 Later, buildings called ice houses or ice pits (坑) were built based on the idea of the Yakhchal. 57 A larger above-ground building covered the pit. Ice houses were very common by the 1800s. This is also when ice delivery (运送) became common. At the end of the19th century, many people kept their food fresh in iceboxes made of wood. These boxes held large blocks of ice to keep food cool. 58 By the 1930s, many people were using electric refrigerators to keep food fresh. 59 Many refrigerators today come with built-in water filters (过滤器) and ice makers. Some people even choose smart refrigerators that can help them plan meals. A.They were stored there after dinner. B.People today have many ways to store food. C.This allowed people to save food in times of need. D.They were cooled by an underground pit full of ice. E.Before then, people found other ways to store their food. F.Ice delivery businesses grew as more homes required ice to preserve food. G.Since then, growth in technology has led these machines to become more advanced. 四、任务型阅读 阅读下面短文,按要求完成下面小题。 Nature has many ways to solve problems. We humans learn a lot from animals and plants in nature. There is a science about how we copy great ideas from helpful animals and plants to create helpful products. It is called biomimetics (仿生学). Some animals such as this sugar glider have wing-like structures (结构) to help them fly from tree to tree. When they jump, they spread out their arms and legs to help them fly down easily. The idea of wing-suits, a kind of clothes which can let people experience flying, comes from the sugar glider. Some animals have structures used for self-protection. An armadillo has a hard cover that can protect it from other dangerous animals. When an armadillo feels that it is in danger, it will change into a ball. Once the dangerous animal goes away, it comes out of the ball. The armadillo has taught people to create a backpack with a hard surface. The surface of the backpack protects things inside from being broken. Plants have helped people come up with amazing inventions, too. Perhaps the best-known example is Velcro (尼龙粘扣). It includes two pieces of cloth. They stick to each other when they are pressed together. Velcro can be found now on everything from handbags to clothes. The idea of Velcro is from burrs (带芒刺的小果实) of a plant. They have special structures to allow themselves to stick to people’s clothing or hair. They are then taken to other places so that they can spread their seeds. From these examples, we can see biomimetics is widely used in our daily life. What other problems will nature help us solve in the future? Let’s wait and see! 60.What is biomimetics according to the text? 61.What does the sugar glider inspire humans to invent? 62.How does an armadillo protect itself when it is in danger? 63.What’s the special structure of burrs actually used for? 64.What do the plants and animals in the text have in common? 五、选词填空 请从方框内选择适当的词并用其正确形式填空,使文章完整连贯。注意每空一词,每词仅用一次,有两词为多余项。请将答案写在答题卡对应题目的答题位置上。 we make helpful from carefully partners because for good think so practice AI is becoming more and more popular in our daily life. It has changed the way we live, work and study. Many families have AI speakers at home. They can play music, tell stories and even control the lights. For students, AI tools can be very 65 . They can answer questions and explain difficult knowledge. Some AI apps can also help us 66 English speaking. However, AI also has some problems. For example, some students depend too much on it. AI is used by them to do their homework without 67 . This is not good for their study. What’s more, AI may make some people lose their jobs 68 it can do many things better and faster than humans. As students, how should we use AI? First, we should think of AI systems as tools and 69 , not a replacement. We can use it to get information and solve problems, but we must think 70 by ourselves. Second, we should learn about AI works. This can help us prepare 71 the future. Finally, we should remember that AI is 72 by humans. We should control it, not let it control us. In the future, AI will develop faster than now. It will bring more convenience to 73 , but we need to use it in the right way. Only in this way can we use AI to create a 74 world. That is the path to a brighter future. 六、短文填空 用括号内所给词的正确形式填空。 Mount Tai has long been famous for its beautiful views. The mountain attracts millions of visitors every year. However, all of 75 (they) face the same problem. They have to take more than 7,000 steps to get to the top of the 1,545-meter-high mountain! Earlier this year, some of the mountain 76 (climber) received help from exoskeleton robots (外骨骼机器人). They provided extra power for people’s legs. Weighing just 1.8 kilograms, this robot locks around the waist (腰) and legs.

The little robots allow farmers to free their soils from chemicals. Using fewer chemicals is going to conserve much money and is good for the environment. As well as reducing the use of chemicals, robots will bring us better soil quality and more plants and animals. “We have to change farming now, or else there won’t be anything to farm,” says Small Robot. 41．We can know the three robots ________ from Paragraph 1. A．are huge B．work in a field C．can plant grass D．come from America 42．The underlined word “conserve” probably means “________” in the passage. A．save B．manage C．divide D．punish 43．Which of the following is TRUE according to the passage? A．Small Robot is a British company. B．Dick’s job is to dig holes and plant seeds. C．Tom can decide what weather crops need. D．Harry never plants new seeds when they don’t grow. 44．What is the best title for the passage? A．The History of Robots B．A British Company’s New Business C．Three Smart Robots Changing Farming D．How to Reduce Chemical Usage in Fields C ①Even though the world has made great efforts to protect African elephants, many of them are still being killed for their ivory. At the end of the 1970s, over 1.3 million elephants walked around Africa. But today, their numbers have fallen to around 450,000. This is mainly caused by illegal (非法的) hunting (狩猎) for ivory. Need for ivory in markets, especially in Asia and Africa, continues to push the illegal trade (贸易). This has resulted in the deaths of at least 20,000 African elephants each year. ② Ivory, also known as “white gold”, has long been regarded as precious. Because of its unusual look, people often use it to make expensive things, such as jewellery (珠宝), musical instruments and art. And the ivory material itself can stand the test of time. That’s why many people are willing to pay high prices for ivory products. ③ However, no matter how much real ivory is sold, it’s certainly not worth the harm to elephants. So some scientists are working hard on creating the same beauty of ivory with no killing. ④ Thaddäa Rath and her team at the University of Vienna have created the man-made ivory called “Digory”. It is made from synthetic resin (合成树脂) and calcium phosphate particles (磷酸钙颗粒). First, they use a 3D printer (打印机) to make the shape. Then they color-match and stain (着色) it. Finally, they polish (抛光) it to make it look like real natural ivory. Although the chemical structure (化学结构) of Digory is completely different from that of the natural ivory, it looks so real that it is hard to tell the difference by eye. ⑤ Fritz Vollrath, a biologist (生物学家) from the UK, felt excited about the invention for the fact that Digory could save many elephants from risks. He said, “We hope that, by doing more research, Digory will soon be accepted and used worldwide. And I believe that technology like this will play an important role in wildlife protection.” 45．Why does the writer list some numbers in Paragraph 1? A．To present the number of elephants in Africa. B．To introduce the ivory markets in Asia and Africa. C．To explain the reasons for the illegal trade of ivory. D．To show the dangerous situation of African elephants. 46．What does the underlined word “precious” in Paragraph 2 mean? A．Modern. B．Valuable C．Beautiful. D．Traditional 47．What do we know about Digory from Paragraph 4? a. Why Digory is invented. b. How Digory is made. c. What Digory is made from. d. Whether Digory looks real. A．abc B．acd C．bcd D．abd 48．Which of the following does Fritz Vollrath agree with? A．Digory will save all the elephants from risks. B．It’s hard for the world to accept man-made ivory. C．It will take long to make Digory used worldwide. D．Technology will support the protection of wildlife. 49．Which is the RIGHT structure of the passage? A．①/②/③/④/⑤ B．①/②③④/⑤ C．①②③④/⑤ D．①/②/③④/⑤ D What Makes an Idea Powerful? Have you ever wondered why some ideas change the world while others disappear quickly? Scientists and thinkers have studied this question for a long time. They have discovered that powerful ideas share some common features. First, powerful ideas solve a real problem. Thomas Edison didn’t just invent the light bulb for fun. He wanted to solve the problem of darkness. Before the light bulb, people used candles and oil lamps, which were dangerous and gave little light. Edison’s idea met a real need, which is why it became so successful. Similarly, the Wright brothers built the first airplane because people wanted to travel faster and further. Second, powerful ideas come to life through hard work and persistence. Many inventors fail hundreds of times before they succeed. Edison famously said, “I have not failed. I’ve just found 10,000 ways that won’t work.” This shows that great ideas don’t come easily. The key is to keep trying and learn from each failure. Third, powerful ideas are shared with others. An idea that stays in someone’s mind can never change the world. That’s why inventors and thinkers often write books, give lectures, and work with teams to spread their ideas. For example, the Internet started as a small idea in one research lab but grew into a global system because thousands of people shared and developed it together. Fourth, powerful ideas often come from curiosity. People who are curious ask questions like “Why is this the way it is?” or “Is there a better way?” These questions open the door to new possibilities. Many of the most important inventions in history were created by curious people who never stopped asking questions. Finally, powerful ideas are often simple but profound. They don’t need to be complicated to be effective. The idea that everyone should be able to read and write, for example, has changed countless lives. 50．According to the passage, why did Thomas Edison invent the light bulb? A．Because he wanted to become famous. B．Because he wanted to solve the problem of darkness. C．Because he needed a new project. D．Because he wanted to prove he was smart. 51．What does Edison’s quote “I have not failed. I’ve just found 10,000 ways that won’t work.” teach us? A．Failure is shameful. B．Great ideas come easily. C．We should give up when things get hard. D．Failure is part of the learning process. 52．According to the passage, why is it important to share ideas? A．Because ideas can only change the world when shared. B．Because sharing ideas makes people famous. C．Because everyone should have the same ideas. D．Because it is easy to share ideas. 53．What does the underlined word “profound” in the last paragraph most probably mean? A．Simple and easy. B．Deep and meaningful. C．Long and complicated. D．Boring and useless. 54．What is the main purpose of this passage? A．To explain what makes an idea powerful. B．To describe different types of inventions. C．To compare famous inventors. D．To encourage people to become inventors. E 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 Life today would be quite different without refrigerators. How did people keep their food fresh before these machines were around? The first electric refrigerator was made in 1913. 55 In cold areas, ancient people could freeze (冷冻) their food. They could then store it in ice and snow. Warmer places allowed for drying food in sunlight. One advanced method of food storage appeared in Persia around 400 BCE. People there stored food in buildings called Yakhchal. They were made from mud (泥) brick to keep ice frozen during even the warmest summer months. During the Middle Ages, people preserved meat by salting or smoking it. They would also dry many foods, including grains. Vegetables were often salted. Many fruits were dried or turned into preserves. These foods could then be stored in cool places. 56 Later, buildings called ice houses or ice pits (坑) were built based on the idea of the Yakhchal. 57 A larger above-ground building covered the pit. Ice houses were very common by the 1800s. This is also when ice delivery (运送) became common. At the end of the19th century, many people kept their food fresh in iceboxes made of wood. These boxes held large blocks of ice to keep food cool. 58 By the 1930s, many people were using electric refrigerators to keep food fresh. 59 Many refrigerators today come with built-in water filters (过滤器) and ice makers. Some people even choose smart refrigerators that can help them plan meals. A．They were stored there after dinner. B．People today have many ways to store food. C．This allowed people to save food in times of need. D．They were cooled by an underground pit full of ice. E．Before then, people found other ways to store their food. F．Ice delivery businesses grew as more homes required ice to preserve food. G．Since then, growth in technology has led these machines to become more advanced. 四、任务型阅读 阅读下面短文，按要求完成下面小题。 Nature has many ways to solve problems. We humans learn a lot from animals and plants in nature. There is a science about how we copy great ideas from helpful animals and plants to create helpful products. It is called biomimetics (仿生学). Some animals such as this sugar glider have wing-like structures (结构) to help them fly from tree to tree. When they jump, they spread out their arms and legs to help them fly down easily. The idea of wing-suits, a kind of clothes which can let people experience flying, comes from the sugar glider. Some animals have structures used for self-protection. An armadillo has a hard cover that can protect it from other dangerous animals. When an armadillo feels that it is in danger, it will change into a ball. Once the dangerous animal goes away, it comes out of the ball. The armadillo has taught people to create a backpack with a hard surface. The surface of the backpack protects things inside from being broken. Plants have helped people come up with amazing inventions, too. Perhaps the best-known example is Velcro (尼龙粘扣). It includes two pieces of cloth. They stick to each other when they are pressed together. Velcro can be found now on everything from handbags to clothes. The idea of Velcro is from burrs (带芒刺的小果实) of a plant. They have special structures to allow themselves to stick to people’s clothing or hair. They are then taken to other places so that they can spread their seeds. From these examples, we can see biomimetics is widely used in our daily life. What other problems will nature help us solve in the future? Let’s wait and see! 60．What is biomimetics according to the text? 61．What does the sugar glider inspire humans to invent? 62．How does an armadillo protect itself when it is in danger? 63．What’s the special structure of burrs actually used for? 64．What do the plants and animals in the text have in common? 五、选词填空 请从方框内选择适当的词并用其正确形式填空，使文章完整连贯。注意每空一词，每词仅用一次，有两词为多余项。请将答案写在答题卡对应题目的答题位置上。 we   make   helpful   from   carefully   partners   because   for   good   think   so   practice AI is becoming more and more popular in our daily life. It has changed the way we live, work and study. Many families have AI speakers at home. They can play music, tell stories and even control the lights. For students, AI tools can be very 65 . They can answer questions and explain difficult knowledge. Some AI apps can also help us 66 English speaking. However, AI also has some problems. For example, some students depend too much on it. AI is used by them to do their homework without 67 . This is not good for their study. What’s more, AI may make some people lose their jobs 68 it can do many things better and faster than humans. As students, how should we use AI? First, we should think of AI systems as tools and 69 , not a replacement. We can use it to get information and solve problems, but we must think 70 by ourselves. Second, we should learn about AI works. This can help us prepare 71 the future. Finally, we should remember that AI is 72 by humans. We should control it, not let it control us. In the future, AI will develop faster than now. It will bring more convenience to 73 , but we need to use it in the right way. Only in this way can we use AI to create a 74 world. That is the path to a brighter future. 六、短文填空 用括号内所给词的正确形式填空。 Mount Tai has long been famous for its beautiful views. The mountain attracts millions of visitors every year.
