What will you do? Long ago, people used 1 things after using the toilet. For example, the Romans used a sponge (海绵) on a stick in salt water. Can you imagine this? It might feel like a 2 today. It is said that the earliest recorded toilet paper dates back to ancient China, and in 1391, the Ming emperor used large sheets with flowers’ smell. Later, people reused old newspapers 3 printing became more common. In 1857, Joseph Gayetty sold flat paper in the U.S., but people didn’t like it. The toilet paper 4 truly started in 1897 when the Scott brothers sold toilet paper in rolls. In 1942, during World War Ⅱ, an English company 5 two-layer paper—soft and strong. Decades later, colorful paper with nice smells came into being, along with some fun paper. 6 cleaning, the fun paper had puzzles or even novels printed on it (like in Japan)! From smelly sponges to story paper, toilet paper’s story is interesting and amazing! 1．A．strange B．convenient C．severe D．useless 2．A．condition B．development C．punishment D．progress 3．A．before B．after C．though D．while 4．A．factory B．industry C．network D．community 5．A．grew B．deepened C．concluded D．developed 6．A．Besides B．Except C．Without D．By Have you ever wanted to send a message to your future self? Or let people 50 years from now know what your life is like today? There’s a fun way to do this—it’s called a “time capsule”! People often 1 small groups of things or information and put them in a safe place. One of the earliest time capsules was the Detroit (底特律) Century Box. On December 31, 1900, the city put several photos and letters in a box. The box wasn’t opened 2 people took it out on December 31, 2000. The things inside the capsule gave us a look at Detroit in the past. There were photos of people and places, as well as letters written by local people. Some of them also made 3 predictions for the future. For example, one person predicted that Detroit would have a population of 4 million by 2000. But 4 , the population of the city was 951,000 that year. Humans have 5 sent time capsules into space! The US sent two capsules into space on the Voyager spacecraft in 1977. They’re called the Voyager Golden Records. They contain 6 and pictures that show human life and culture. For example, they have music by classical musician Beethoven and pictures of plants, insects and landscapes. The Voyager spacecraft has traveled far away from our solar system. It is hoped that aliens (外星人) might find the time capsules someday and learn about humans. 1．A．display B．collect C．send D．hide 2．A．until B．when C．after D．since 3．A．rare B．ordinary C．surprising D．right 4．A．in fact B．at first C．in total D．at last 5．A．never B．even C．hardly D．seldom 6．A．letters B．movies C．books D．sounds Choose the best answer and complete the passage (选择最恰当的选项完成短文) Have you ever heard that some of the world’s most important discoveries happen by accident? The story of penicillin (青霉素) is one such example. This life-saving 1 was discovered through a lucky accident by a scientist named Alexander Fleming. In September 1928, Fleming was working in his laboratory in London. He was studying staphylococcus bacteria (葡萄球菌)，which can cause serious 2 in people. They felt weak. Before leaving for a vacation, he left some polluted dishes with bacteria in his lab by chance. When he returned, he noticed something 3 . A blue-green mold (青绿霉菌) had grown on one dish, and around it was a clear circle where all the bacteria had died. Instead of throwing away the polluted dish, Fleming became very 4 . He thought the blue-green mold might produce something that could kill bacteria. He decided to test this idea by doing more experiments. He found that the mold juice was indeed very effective at 5 harmful bacteria. He named this amazing mold “penicillin”. What made penicillin so special was that it could kill bacteria without harming human cells. This meant it could be used safely to treat sick people. Fleming’s discovery opened a new chapter in medicine-the age of antibiotics (抗生素). It completely changed how doctors treat bacteria and has 6 countless lives around the world. This wonderful story teaches us that in science, keeping an open mind and being curious can sometimes lead to amazing discoveries that change the world. 1．A．food B．medicine C．drink D．plant 2．A．illness B．challenges C．accidents D．disasters 3．A．usual B．strange C．wrong D．missing 4．A．angry B．curious C．tired D．worried 5．A．helping B．growing C．destroying D．finding 6．A．saved B．supported C．lost D．taken Choose the words or expressions and complete the passage. (选择最恰当的单词或短语完成短文) A Helping Hand Easton LaChappelle was just 14 years old when he first showed a robotic arm at a science fair. Unlike other complex devices, it was a 1 project made of plastic blocks and fishing line, but it caught the attention of a girl with a very special story. The girl, Jenny, was born without an arm. Her current artificial arm was just a basic hook (挂钩), which cost an unbelievable 80,000 dollars. Worse still, children like her grow fast, so they need to 2 their prosthetic arms often. “It was expensive and not user-friendly,” Easton thought 3 he shook hands with her. “I built mine for only 300 dollars. I can do something for them—I have to make greater progress!” Back at home, Easton turned his room into a laboratory. Day and night, he 4 making his designs better. For his 16th birthday, he got a 3D printer, which allowed him to create parts more easily. With it, he invented a new arm that could be controlled by the user’s brain signals. However, the arm had a big problem: it weighed 3.6 kilograms, which was too heavy for a child to use comfortably. Easton didn’t give up. He kept solving one problem after another. 5 at the age of 23, he succeeded. His new design was light—only 0.5 kilograms—and much cheaper, costing around $500. But Easton didn’t want to make money from his invention. “I just wanted to help,” he said. So he posted the design online 6 . Now, anyone with a 3D printer can download the design and make an artificial arm for those in need. Easton’s story is truly a “helping hand”—not just for Jenny, but for more children around the world. 1．A．clear B．simple C．private D．recent 2．A．touch B．press C．change D．shake 3．A．after B．because C．if D．though 4．A．depended on B．called on C．worked on D．put on 5．A．Finally B．Surprisingly C．Carefully D．Continuously 6．A．at once B．for free C．by himself D．in conclusion A mobile phone app has recently become very popular at the Middle School Attached to Guangzhou University. The app’s name is Health Helper. Put your weight, height and 1 into the app, and it will give you suggestions on how to get healthier. 2 , the app is not designed by a company but by two Junior 3 boys from the school. The two boys are Yang Chengxi and Yang Zhenglin, both 14 years old. They learned to design apps by taking part in the school’s app-making course, which started last year. “Electronic products are becoming increasingly popular,” said Wang Xiaopeng, the teacher of the app-making course. “It’s impossible to block (阻隔) students from them. So why not lead them to use it in a 3 way?” The course has 4 many students including Yang Chengxi and Yang Zhenglin. As cellphone game lovers, the two students study hard on their app-making project. “It is much cooler to design a game than just to play a game,” said Yang Chengxi. They decided to create an app to keep healthy because obesity (肥胖) has become a problem for many teenagers. They searched for a lot of health information on the Internet, put them in the app and wrote simple programmes to make it work. 5 the app-making software, the two boys finished their Health Helper app after three weeks of hard work. The taste of 6 is exciting. After Health Helper, the two now plan to go a step further. They are working on a robot that can be controlled by a cell phone’s Bluetooth.

He spent hours observing birds in flight, water flowing and plants growing. While studying bird wings, he made a detailed 2 : the same mathematical patterns appeared in nature again and again. This finding led him to create wonderful drawings of flying machines that were centuries ahead of his time.Tu Youyou and ancient medicine When malaria (疟疾) spread in the 1960s, scientist Tu Youyou turned to ancient Chinese medical texts for answers. While many 3 focused on modern chemistry, she was particularly persistent (坚持不懈的) about traditional remedies. After reviewing over 2,000 old recipes, her team finally 4 an extract (提取物) from sweet wormwood that proved effective against malaria. Her curiosity about ancient wisdom saved millions of lives and earned her the Nobel Prize.Tim Berners-Lee and information sharing As a young software engineer, Tim Berners-Lee grew frustrated (受挫的) with how difficult it was to share information between computers.

(选择最恰当的选项完成短文) It was fantastic to go to the Science Museum to see an exhibition about driverless vehicles (交通工具). Before my visit to the museum, I didn’t know much about vehicles that drive themselves using computer controls. Driverless cars might seem like something from 1 , but they’ve been around longer than we think. I learned that the first of them appeared years ago. It was a car called the Citroen DS19, which appeared back in 1960. It drove itself by 2 a network of cables (电缆) buried underground. Driverless vehicles have developed a lot since then. Newer ones are used for different purposes, like helping farmers by picking crops, or helping scientists by exploring under the ice. The exhibition was organized into three different areas. Each one 3 a different subject. The first was called “Land.” I was able to look at how driverless vehicles were already being used on land, and possible developments that would happen in the future. The issue of 4 is a big one. How can a driverless car make the right choices that a human makes in an emergency situation? Scientists are working on ways to solve this problem. I understood more about how difficult it was when I was playing with the interactive displays (交互式显示屏). Doing this let me see the world through the “eyes” of a driverless car. It’s very 5 to program a computer to make the decisions a human driver usually makes. In the zone called “Water,” driverless vehicles are being used to make maps of the sea floor and to understand how climate change is affecting the oceans. And in the final area, “ 6 ,” I learned about the flying drones (无人机) that are being developed to deliver products, but not just for shoppers. They’re also important for things like medical emergencies.

The biggest secret about inventing is that anybody can do it! Perhaps this sounds crazy, but it’s true. Maybe you have the wrong idea about inventing, so read on to discover the 1 . Wrong idea number 1: An invention has to be something completely new. Well, inventing means creating something “new”, but the idea could come from something that already 2 . The Wright brothers, for example, got the idea for building a “flying machine” from watching birds. Wrong idea number 2: Inventors are born, not made. There are a lot of factors (因素) that make innovation 3 . Take Mozart, for example. He was born with a unique talent for musical composition. But other factors were also important for his creativity. His father was a music teacher, and Mozart 4 for hours every day, from the time he was in kindergarten. Thomas Edison said that being an inventor was “99% hard work and 1% inspiration”! Very successful creators don’t 5 when they get something wrong. As one inventor said, “A failure is the right answer to the wrong question!” Wrong idea number 3: Inventors are always 6 people. Don’t believe that you can’t invent something when you are young. Here is an example of a young inventor: Louis Braille went blind when he was a child. When he was 15, he invented a system of reading and writing for blind people that is still used in most countries today. 1．A．truth B．cause C．detail D．land 2．A．happens B．finishes C．exists D．matters 3．A．easy B．possible C．special D．interesting 4．A．fought B．dreamed C．argued D．practised 5．A．give up B．run away C．work hard D．turn back 6．A．clever B．healthy C．old D．strange 重难语篇练习 Choose the words or expressions and complete the passage (选择最恰当的单词或短语完成短文) The History and Future of Comic Strips Have you ever read a comic strip in a newspaper or online? You know, those funny little stories with pictures and speech bubbles? They might seem simple, but comic strips have a rich history and a bright future. Let’s dive into their story and see how they have 1 over time! Comic strips started over a century ago. At first, they were short, funny stories in newspapers. People loved them because they were easy to read and made them laugh. Early comic strips often had regular 2 who often got into silly situations. These strips became so popular that they helped sell more newspapers. As time went on, comic strips changed gradually. They weren’t just funny anymore. Some told 3 stories or explored deep themes. Artists experimented with different styles, and new characters were created. Comic strips became a way to entertain people, share ideas and even express opinions on society. However, in recent years, the comic strip market has become weaker. Fewer people read newspapers, which used to be the main home for comic strips. Many newspapers have reduced the 4 for comics or stopped printing them at all. This has made it harder for artists to earn money from their work. Some people worry that traditional comic strips might disappear, replaced by faster, shorter forms of entertainment like videos. But don’t worry! Comic strips are still alive! Today, they’ve found a new home. Many artists create digital comic strips and share them 5 . This has made comic strips easier to find than ever. People from all over the world can enjoy them with just a click. What about the future? Comic strips will likely keep changing. With new technology, we might see more interactive comic strips. Readers can click or swipe to create the story. Some artists use AI to bring their strips to life. The 6 are endless! So, whether you’re a longtime fan or new to comic strips, there’s something for everyone. What’s your favorite comic strip? Let me know. I’d love to hear about it! 1．A．developed B．appeared C．succeeded D．linked 2．A．enemies B．readers C．characters D．directors 3．A．amusing B．serious C．creative D．essential 4．A．cost B．waste C．space D．stress 5．A．on the internet B．through magazines C．on TV D．by E-mail 6．A．responsibilities B．celebrations C．discussions D．possibilities 选择最恰当的选项完成短文。 Company Creates First 3D-Printed Fish Do you enjoy seafood? Many of us do, but overfishing is a problem. There are many ways to respond to this. One is to only eat seafood that is caught through scientific fishing methods. Another is not to eat fish at all. However, a new 1 is 3D-printed fish, which may offer a new way to solve the problem and perhaps be healthier to eat. It sounds like 2 , but it’s happening now. “The product tastes, and melts in your mouth exactly like fish should,” says Mihir Pershad, the CEO of Umami Meats. Umami Meats, a Singapore company, cultivates stem cells (干细胞) taken from live fish. Stem cells are grown in labs for 2 weeks and 3 muscle and fat samples (样本) after another week. The second company, Steakholder Foods, uses the muscle and fat samples in high-tech 3D printers. They are able to 4 the shape and size of the piece of “fish” first, and then mix muscles and fat together. This makes the final product nearly the same as real fish. The ability to create 3D-printed fish is an incredible technological achievement. Umami Meats focuses on helping protect some endangered fish like tuna, reducing the need for overfishing. 3D-printed fish is 5 of harmful chemicals that are common in a lot of seafood. It can also be produced quite cheaply compared to live fish. However, a lot of research on the 6 of eating 3D-printed food needs to be done. This is why restaurants aren’t allowed to serve these products now. The earliest we will see them is likely some time in 2024. 1．A．example B．choice C．decision D．message 2．A．food reports B．dinner menus C．science fiction D．movie reviews 3．A．turned into B．poured into C．looked into D．broken into 4．A．receive B．obey C．explain D．design 5．A．full B．free C．tired D．short 6．A．process B．importance C．safety D．cost 学科网（北京）股份有限公司 $ Unit 2 Great inventions and discoveries 完形填空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 发明与创造 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 Picture this in your mind: You’ve just answered nature’s call, and to your horror, there’s no toilet paper in the bathroom.

He kept solving one problem after another. 5 at the age of 23, he succeeded. His new design was light—only 0.5 kilograms—and much cheaper, costing around $500. But Easton didn’t want to make money from his invention. “I just wanted to help,” he said. So he posted the design online 6 . Now, anyone with a 3D printer can download the design and make an artificial arm for those in need.

(选择最恰当的选项完成短文) It was fantastic to go to the Science Museum to see an exhibition about driverless vehicles (交通工具). Before my visit to the museum, I didn’t know much about vehicles that drive themselves using computer controls. Driverless cars might seem like something from 1 , but they’ve been around longer than we think. I learned that the first of them appeared years ago. It was a car called the Citroen DS19, which appeared back in 1960. It drove itself by 2 a network of cables (电缆) buried underground. Driverless vehicles have developed a lot since then. Newer ones are used for different purposes, like helping farmers by picking crops, or helping scientists by exploring under the ice. The exhibition was organized into three different areas. Each one 3 a different subject. The first was called “Land.” I was able to look at how driverless vehicles were already being used on land, and possible developments that would happen in the future. The issue of 4 is a big one. How can a driverless car make the right choices that a human makes in an emergency situation? Scientists are working on ways to solve this problem. I understood more about how difficult it was when I was playing with the interactive displays (交互式显示屏). Doing this let me see the world through the “eyes” of a driverless car. It’s very 5 to program a computer to make the decisions a human driver usually makes. In the zone called “Water,” driverless vehicles are being used to make maps of the sea floor and to understand how climate change is affecting the oceans. And in the final area, “ 6 ,” I learned about the flying drones (无人机) that are being developed to deliver products, but not just for shoppers. They’re also important for things like medical emergencies.

Many of us do, but overfishing is a problem. There are many ways to respond to this. One is to only eat seafood that is caught through scientific fishing methods. Another is not to eat fish at all. However, a new 1 is 3D-printed fish, which may offer a new way to solve the problem and perhaps be healthier to eat. It sounds like 2 , but it’s happening now. “The product tastes, and melts in your mouth exactly like fish should,” says Mihir Pershad, the CEO of Umami Meats. Umami Meats, a Singapore company, cultivates stem cells (干细胞) taken from live fish. Stem cells are grown in labs for 2 weeks and 3 muscle and fat samples (样本) after another week. The second company, Steakholder Foods, uses the muscle and fat samples in high-tech 3D printers. They are able to 4 the shape and size of the piece of “fish” first, and then mix muscles and fat together. This makes the final product nearly the same as real fish. The ability to create 3D-printed fish is an incredible technological achievement. Umami Meats focuses on helping protect some endangered fish like tuna, reducing the need for overfishing. 3D-printed fish is 5 of harmful chemicals that are common in a lot of seafood. It can also be produced quite cheaply compared to live fish. However, a lot of research on the 6 of eating 3D-printed food needs to be done. This is why restaurants aren’t allowed to serve these products now. The earliest we will see them is likely some time in 2024. 1．A．example B．choice C．decision D．message 2．A．food reports B．dinner menus C．science fiction D．movie reviews 3．A．turned into B．poured into C．looked into D．broken into 4．A．receive B．obey C．explain D．design 5．A．full B．free C．tired D．short 6．A．process B．importance C．safety D．cost 【答案】1．B 2．C 3．A 4．D 5．B 6．C 【导语】本文主要介绍了有公司创造出了第一条3D打印鱼。 1．句意：然而，一种新的选择是3D打印的鱼，它可能提供一种解决问题的新方法，也许吃起来更健康。 example例子；choice选择；decision决定；message信息。根据“There are many ways to respond to this”和“However, a new...is 3D-printed fish”可知，此处表示一种新的方法，即新的选择。故选B。 2．句意：这听起来像科幻小说，但它正在发生。 food reports食物报告；dinner menus晚餐菜单；science fiction科幻小说；movie reviews电影影评。结合语境和“but it’s happening now”可知，3D打印鱼听起来像是科幻小说，但它的确正在发生，but前后为转折关系。故选C。 3．句意：干细胞在实验室中培养两周，再培养一周后转化为肌肉和脂肪样本。 turned into变成；poured into倒入；looked into调查；broken into闯入。根据“Stem cells are grown in labs for 2 weeks and...muscle and fat samples (样本)”可知，细胞培养一段时间之后应该是会变成肌肉和脂肪。故选A。 4．句意：他们能够首先设计出“鱼”的形状和大小，然后将肌肉和脂肪混合在一起。 receive收到；obey遵守；explain解释；design设计。根据“They are able to...the shape and size of the piece of ‘fish’ first...This makes the final product nearly the same as real fish”可知，是先设计出“鱼”的形状和大小。故选D。 5．句意：3D打印的鱼没有很多海产品中常见的有害化学物质。 full充满；free不含……的；tired劳累的；short短缺的。根据“...3D-printed fish, which may offer a new way to solve the problem and perhaps be healthier to eat”和“3D-printed fish is...of harmful chemicals that are common in a lot of seafood”可知，3D打印的鱼可能吃起来更健康，故应该是没有很多海产品中常见的有害化学物质，be free of“没有”。故选B。 6．句意：然而，关于食用3D打印食品的安全性还需要进行大量的研究。 process步骤，程序；importance重要性；safety安全；cost花费，成本。根据“This is why restaurants aren’t allowed to serve these products now”可知，餐馆现在还不允许供应这些产品，故可推测出，食用3D打印食品的安全性还需要进行大量的研究。故选C。 学科网（北京）股份有限公司 $
