Building the world’s first floating city
The Maldives is building a floating city to deal with the rising sea level
马尔代夫建设世界上首座漂浮城市
Have you ever imagined living on the sea This idea could soon come true. The Maldives is building the world’s first floating (漂浮的) city and plans to complete it in 2027.
The city is like a man-made island. People will live on floating platforms (平台). These platforms are connected and placed along a hexagonal grid (六角网格). Natural coral reefs (珊瑚礁) will be grown around the city to keep the floating city stable (稳定的), so people who live here won’t feel seasick.
People will live a self-sufficient (自给自足的) life in the floating city. Electricity will be powered by solar energy (太阳能). Sewage (污水) will be treated there. More importantly, the island is not far away from land. It takes only 10 minutes to travel by boat between there and the capital of the Maldives.
Cool as it seems, the city is designed to solve real problems. The Maldives is one of the world’s lowest-lying countries. Most of its islands—including the capital—stand about 1 meter above sea level. And now climate change has brought a big problem—the rising sea level. According to CNN, 80 percent of the country’s land area will be under the sea by the end of the century.
“In the Maldives, we cannot stop the waves, but we can rise with them,” Mohamed Nasheed, former president (前总统) of the country, told Newsweek magazine.

Huang Xuhua is a remarkable figure in China’s history of national defense. He is widely known as the “Father of China’s Nuclear-powered Submarines”.
In the 1950s, China faced great challenges in national defense. To strengthen the country’s naval power, Huang Xuhua dedicated himself to the research and development of nuclear-powered submarines. At that time, the research conditions were extremely difficult. There was a lack of advanced technology and experience, and the international community imposed strict technological blockades. But Huang Xuhua and his team did not give up.
They spent countless days and nights in the laboratory and on the construction site. Huang Xuhua often worked around the clock, sacrificing his personal time and family life. Through their unremitting efforts, in 1970, China’s first nuclear-powered submarine was successfully launched. This was a huge milestone in China’s naval development, greatly enhancing China’s national defense capabilities.
Huang Xuhua’s contributions are not only limited to the successful development of nuclear-powered submarines. He also trained a large number of outstanding scientific and technological talents for China. His spirit of dedication, perseverance, and innovation has inspired generations of Chinese people. Even in his later years, he still cares about the development of China’s submarine technology and is always ready to offer his wisdom and experience.

Feng Boyao and Meng Shuqi found that their city library didn’t have enough Braille books (盲文书籍) for blind people and many of the Braille books were outdated. So, they teamed up to help the blind by fixing the problem. Feng and Meng both studied at No 37 Middle School in Taiyuan, Shanxi province. They invented a new kind of Braille reader. Their work won first prize in a national competition aiming to nurture creative thinking by encouraging youths to solve social problems. The invention was also granted (授予) a national patent (专利).
When connected to a computer, their Braille reader can turn words into raised dots (凸起的点). Blind people can read by touching the dots, which are magnets (磁铁). This is the first Braille reader that uses magnets.
“We found that today’s Braille readers are very difficult and expensive,” Feng said. “So, we decided to develop a user-friendly product, especially for young blind children from grades 1 to 3. Moreover, it only costs about 2,000 yuan.”
After making their first device, Feng and Meng visited a school for the blind to get advice and improved it based on the students’ needs, like changing the size of the screen and the amount of space between the dots.
“We hope the invention will be popularized (普及) in the future to help those blind people who can’t afford the Braille reader now,” Meng told Taiyuan News.

①Do you know the dragon and Kun I think most of you must know the dragon, because it is one of the symbols of China. But probably very few people know about the Kun. It is a fish from ancient Chinese stories. The fish is huge and lives in the northern sea. Kunlong AG600, the Chinese made large amphibious aircraft (水陆两栖飞机), was named after these two symbols. The meaning of the name is to fly into the high sky like a dragon and go down to the deep sea like a Kun.
②On February 25, 2023, the fourth AG600M firefighting aircraft prototype (消防飞机原型机), belonging to the AG600 large amphibious aircraft family, carried out its first flight (飞行) in Zhuhai. During the 17 -minute flight, the aircraft carried out some planned flight test subjects. And it performed very well. The successful flight of the aircraft showed the start of test flights of all four AG600M aircraft prototypes.
③As a member of the AG600 aircraft family, the AG600M has been developed as a piece of important aeronautical equipment (航空设备) to make China’s ability to save people in dangerous situations stronger. It can be used in putting out forest fires, doing sea search and other tasks.
④The AG600 aircraft family made great progress in 2022, especially both aircraft development and market exploration (开拓). The year of 2023 is the key to the development of aircraft. A number of flight tests and ground tests are planned this year to make sure that the AG600M is able to put out fires.
⑤It will be useful for emergency saving and prevention systems. Let’s wait and see.

Do you play an instrument Have you ever made one Terje Isungset can answer yes to both questions. And he makes instruments out of something pretty cool. Ice!
Isungset got the idea for ice music more than 20 years ago. “I was asked to do a concert in a frozen water fall, ” he says. This gave him the idea to play instruments that were actually made out of ice. As far as he could tell, this hadn’t been done before. “There were no books to read about it-nothing on the Internet,” he says. “So I had to create everything by myself. ”
In 2006, Isungset helped start the Ice Music Festival. It is held in February. Almost everything at the Ice Music Festival is frozen. “As you can imagine, there are a lot of things to do, ” Isungset says. “We come to a place, we collect the ice, and we build the concert space out of snow and ice.”
For the festival Isungset has a goal of trying to invent a new instrument every year. He is going to play an ice horn (喇叭) this year. “Would your mouth stick to it Many people ask that question, ”
Isungset says. “If the horn was made out of metal (金属), it would get stuck completely.” His solution Use a small piece of leather (皮革) . Place it on the horn’s mouthpiece. “It’s the only part of my instrument that is not made of ice.”
17．Terje Isungset’s new instruments are mainly made of ________.
A．ice B．paper C．plastic D．wood

Have you ever noticed something around you that you’ve never seen before They all came about because someone invented them. Most inventions begin with an idea. Someone sees a need or a problem. Then he or she thinks of an idea to meet that needs or solve the problem.
But not all inventions happen on purpose. They may be something by working on an idea and invent something else by chance. Or an inventor might make a mistake that turns out to be a good idea.
Between AD 600 and 900, scientists in ancient China were working in a lab when they invented fireworks by accident. They were working on an invention that would help people live forever. They mixed materials together like salt, charcoal (木炭), and sulphur (硫黄). They put the mixture into pieces of bamboo. Then they threw them into a fire. This is how fireworks were invented.
In 1905, a boy named Frank Epperson left a cup of soda (苏打水) outside all night. It had a wooden stick in it. The soda froze in the cold evening. In the morning, Frank tasted the frozen soda. He shared the frozen soda with his friends. All of them spoke highly of his new invention. It tasted really good! He called his invention “Episicle”.
In 1968, scientist Spencer Silver was researching adhesives (黏合剂) when he discovered one that stuck to things, but could then be easily taken away. For years he tried to find a use for his invention. At the same time, another scientist named Art Fry was singing. He used small pieces of paper to mark the songs in his book. He needed bookmarks that would stay in place. Silver and Fry discussed their ideas and created the Post-it note.

Two Swedish students have invented a new kind of bicycle helmet (头盔). It’s invisible (隐形的) because you cannot see it on a rider’s head.
The helmet is really a kind of airbag. It is inside a large collar (衣领). People wear it around their neck like a scarf. When the rider falls off his or her bike, the collar quickly fills with air and an airbag appears around the head.
The two students, Anna Haupt and Terese Alstinat, wanted to change the way people ride bikes. They said, “Bicycle helmets have always been the same. They’re so bulky, like a hard mushroom (蘑菇) on the head.” They called their new invention the H vding. The pair said it looked so cool that people would be happy to wear it.
The inventors started researching and developing the helmet a few years ago. They studied thousands of accidents. They wanted to find out how to make the safest helmet. They worked with a Swedish airbag company called Alva. And then the invisible helmet came out. Today, the two inventors have their own company that sells the new helmets. There are 17 workers in their company. They hope their helmet will change how people all over the world ride bikes.
In their video, Haupt and Alstinat said, “Cars are so yesterday. Bikes are the future.” People can not only take exercise but also experience the beauty of nature when they ride bikes. Now people can only buy the helmet online in Europe. It sells for around $530. The company did not say when people in the rest of the world could buy it.

In the Ming Dynasty, in order to protect the country and people, the emperor decided to rebuild the Great Wall. This is because the Great Wall is not just a wall. The walls were connected by a system (系统) of watchtowers. These were not only used to stop the enemy, but also to communicate with the capital by signals (信号). However, building a wall with huge stones seemed to be impossible at that time.
At that time, the building of Jiayuguan required millions of stones of the same size. People found that neither men nor horses could carry the stones because they were too heavy.
Winter was coming. The workers were worried about whether they can finish the work on time. They gathered every day to discuss the way to carry them. One day, a worker accidentally poured water onto the road, he found the water quickly became ice. He stepped on the ice and almost fell down. Thanks to this “mistake”, he came up with a perfect way—to build an “ice” road. In the end, this way was quickly put into practice. On the ice road, every stone was transported (运输) to the mountain easily. They finally solved the problem with their wisdom and diligence (勤奋).
The building of the Great Wall was not without its challenges, but the workers’ strong will and creativity got over all of them. Today, the Great Wall is not used to protect the country any more, but it is always the symbol of our nation’s spirit. It is the Great Wall that gives us the power to create and the courage to move on and get over all difficulties. We’ll be fearless, and we’ll work together to create the new “Great Wall” of our time.
34．Why was it difficult to build the Great Wall in ancient times
A．Because there was much ice on the wall.
B．Because there were less people do this work.
C．Because it was hard for people to move heavy stones.
D．Because the weather at that time was very terrible.
35．The underlined word “gathered” probably means “________” in the passage.
A．get together B．keep together C．live together D．act together
36．Which of the following can best describe the workers who built the Grate Wall
A．Strict and wise. B．Shy and patient.
C．Honest and friendly. D．Hard-working and smart.
Scientists in Switzerland have used lasers (激光) to change the path of a lightning strike (雷击的路径). The experiment suggests that in the future, lasers might be useful for protecting large buildings from lightning.
Lightning can be extremely powerful and cause serious problems on the ground. Lightning strike can cause fires, destroy buildings, and even kill people. The damage from lightning costs billions of dollars every year. In the US, lightning strikes killed close to 450 people between 2006 and 2021.
Scientists have been trying to find a way to protect buildings from lightning for a long time. Now the best Way is by putting metal rods (金属竿) on the buildings. These rods are connected to the ground. The lightning is attracted to the rods, which safely guide the electricity into the ground. But lightning rods can only protect a small area. Some buildings—such as airports are so large that it’s difficult to protect the whole building using lightning rods.
Another idea is to use lasers to guide lightning. Scientists had been working on the idea for over 20 years. They have successfully guided lightning with lasers inside a lab. But until the summer of 2021, scientists could guide lightning with lasers outside. Using a powerful laser, scientists in Switzerland were able to guide lightning tor meters.
The heat from the laser creates a path of air that is less thick than the air around it. The path also has a special charge (电荷). The lightning can follow this path almost as if it were a lightning rod. Scientist Matteo Clerici said, “The fact that we managed to do it in an outdoor environment is a very big step.”
But the laser still didn’t guide the lightning as far as the scientists would like. Besides, the laser is also very expensive. The scientists say it cost about $2 billion. It will probably take 10 or more years before a laser like this is truly able to protect large buildings.
37．To know how powerful lightning can be, which paragraph can we read
A．Paragraph 2. B．Paragraph 3. C．Paragraph 4. D．Paragraph 5.
38．What is the laser technology expected to protect
A．High-rise buildings. B．Large buildings.
C．Beautiful buildings. D．Important buildings.
39．Why are lasers not used widely for changing the path of lightning strike now
A．Putting metal rods on the buildings is the best way.
B．Some buildings are so large that it’s difficult to protect.
C．Lasers are only able to guide lightning for a short distance
D．Lasers are so expensive that scientists can’t pay for experimenting.
40．What can we learn from what Matteo Clerici said
A．Scientists still need to work harder to achieve a greater success.
B．It is not easy for scientists to guide lightning with lasers outside.
C．Scientists need to change working environment in next experiments.
D．It is a great progress for scientists to guide lightning with lasers outside.
41．What can we get to know at the end of the passage
A．Behind bad luck comes good luck.
B．A journey of a thousand miles begins with a single step.
C．There is still a long way to go before a laser can really work.
D．For scientists, working together is better than working alone.
Technology is helping people to give first aid. It helps save lives faster. Technology not only makes our lives easier, it can also save lives. People who have sudden health emergencies (紧急情况) like heart disease or accidents may only have a few minutes to live unless they get help. We can use technology to offer help faster. Let’s look at some technological inventions that are helping save lives.
Smart app
Some people in the US made an app called Pulse Point. It invites common people trained in CPR (心肺复苏术) to use it. The app knows the users’ locations. If someone needs first aid nearby, a user will get a message asking them to help.
Magic gel (凝胶)
The gel can stop someone bleeding (流血) in just 10 seconds. It is made from plants. It can stick to a wound and help seal (密封) it. It was invented more than 10 years ago but was only allowed to be used on animals. Now in the US, it has been allowed to be used on humans, too. And the person from the US was only 17 years old when he invented it!
Flying aid
If people get injured or need help in hard-to-reach areas, drones (无人机) can be of great use. Because they can fly, drones can often offer help faster than people. And they can also make helping people safer for rescuers (营救者) working in dangerous conditions. The drones can have a camera that can watch your health. They can also carry useful things, like blankets or a life jacket to save someone from drowning (溺水).
42．How many technological inventions are mentioned in the text
A．2. B．3. C．4. D．5.

Scientists are known for being creative and full of new ideas. Recently, they added amazing ideas to the following inventions that make a big difference to people’s lives.
The Robot SuitcaseIf you are afraid to forget something at the airport, you will love the idea behind this robot suitcase. First, the suitcase can follow its owner. It can also stay away from other things on its way. It can even call the police when someone is trying to take it away.
Electronic ChopsticksScientists at an American university have invented a pair of electronic chopsticks that can change the taste of food. When you put the chopsticks in your mouth, they can make the taste become better, such as making sweet food taste sweeter or salty food less salty. Soon the scientists are going to try their technology on bottles, cups and spoons.
Talking GlovesA pair of gloves helps people to communicate with someone who has hearing and speaking problems. The gloves are equipped with sensors (传感器). They recognize body language and translate it into text on a smartphone. Then the smartphone changes the text to spoken words. Thus, you can understand disabled people’s body language easily.
Environmental ShoesEvery step you take is helping cut down the air pollution. This is not in science fiction. A team from Europe has invented such a pair of shoes. The shoes can take in dirty air and send out clean air. If you wear the shoes and walk one kilometer, the shoes can clean the air polluted by eight cars.

You don’t have to be old to be an inventor. Frank Epperson invented the Popsicle when he was just eleven years old. One winter day in 1905, after a day of play, he left his drink outside with the stir stick (搅拌棒), he found his drink was frozen like an icicle (冰柱). Frank tasted it and found it was delicious. And it became a hit with his friends.
When he grew up, Frank Epperson sold land and houses for a living. By 1921 he had to make a living for his wife and five children. But Frank never forgot the frozen treat (冰品) that he had discovered. He decided to continue with it. He soon started a business—selling the frozen treats in seven flavours (口味). He named the ice on a stick “Epsicle”. His children didn’t think that was a very good name. They called the frozen treat “Pop’s sicle”. The name was later changed to “Popsicle”. In 1924 Frank got a patent (专利) for his frozen treat.
During the late 1920s and the 1930s, the United States went through hard times. Many people lost their jobs. Twin ice pops (双棒棒冰) with two sticks were invented. They were just five cents and two children could share them.
Today millions of Popsicles are sold every year. They come in thirty flavours. The most popular flavour is cherry. Now whenever we enjoy ice pops in summer, we have Frank Epperson to thank.
52．What is Paragraph 1 mainly about ________
A．How ice pops are made.
B．What people drank in the 1900s.
C．What happens on cold winter nights.
D．How Frank discovered the frozen treat.
53．The word “it” in Paragraph 2 refers to ________.
A．making a living for his family
B．playing with his friends
C．selling land and houses
D．making his frozen treat
54．Who helped Frank with the name of his frozen treat ________

A．A young scientist
B．A frozen invention
C．A kid’s sweet drink
D．A big business in summer
①Could you imagine being in a car driven by a computer, not a human Recently, China has made a big step toward self-driving technology. Since August, driverless taxis can run on roads in Wuhan, Chongqing and Shenzhen.
②Why do we develop self-driving cars Self-driving cars have many advantages. They use computers to sense the things around them and make better use of space. This means fewer crowded roads and better parking of cars. For disabled or blind people, self-driving cars can also help them get around more easily.
③According to US Centers for Disease Control and Prevention, each year, more than 1.35 million people are killed on roads around the world. Many more are hurt in accidents. Self driving cars could reduce road accidents by 90 percent and save governments a lot of money. The main cause of car accidents is human error (错误). By using computers, self-driving cars don’t make poor decisions or lose attention like humans do.
④But self-driving cars aren’t perfect. If something unexpected on the road happens, self-driving cars can’t react as fast as a human driver can. Also, during weather events like heavy snow, self-driving cars wouldn’t see the lines on the road easily. It might lead to an accident. The car’s computer system would be broken by someone, causing it to crash or change its direction.
⑤It’s clear that there is a lot of work to do to make self-driving cars a common sight on our roads. And China is taking the lead in making this happen.
57．According to the passage, it is ________ to develop self-driving cars for disabled or blind people.

A Bright Idea
Evans Wadongo was from a village of Africa. He had to do homework by the light of a kerosene lamp (煤油灯). Evans’ eyes hurt and this made studying difficult. It was common in his village. Many children left school for this reason, so they remained poor for the rest of their lives.
Although studying was difficult, Evans was an excellent student and went to a university. He continued to worry about the kerosene lamp. By this time, he realized it was not just bad for schoolchildren but for the whole family. First, it can cause illnesses such as coughs. Also, the light can hurt people’s eyes. Besides, it can lead to fires. Lastly, kerosene is expensive, so families have less money for food. It was difficult to come up with a different kind of lamp that was cheap and good for the environment. Yet Evans did not give up.
One day, he had an idea. He could use a small solar light. Sunlight is free and solar power is good for the environment. Evans built his first solar lamp, and it worked. He began to build more lamps and sent them to local families. An organization (组织) heard about this and provided money for him to build more solar lamps.
Each lamp only cost $20. However, this was a lot of money to many villagers, who only earned (挣得) around $34 a week, so Evans made sure he kept the cost down. First, Evans used recycled materials (材料). Next, volunteers built the lamps. Finally, people from many countries gave away money to his team, so the lamps were usually free.
Thousands of people had safe light. Julia, a mother of three, said, “Thanks to Evans, my children have light to read, and I have my own light to cook.” The solar lamps made a big difference.

When Emily Cummins was four years old, her grandfather gave her a hammer (锤子). She loved using it, and started to learn how to make toys from old things that nobody used any more.
66 She always thought a lot about making inventions to help other people. Emily’s grandfather had an illness. He had a lot of pain in his hands and fingers. One day, Emily saw that he had trouble getting toothpaste (牙膏) out of the tube. She made an invention that helped him with this, and won the Young Engineer for Britain Award for her toothpaste dispenser (挤牙膏器).
A few years later, Emily learned about the serious water shortage (短缺) in some African countries. The women and children there often walk many kilometers a day to get water for their villages. They usually put the buckets (桶) on their heads, and they have to walk carefully in order not to spill (溅出) the water. 67 It makes it possible for the women to transport up to five buckets each time. Besides, it is easy for them to repair the water carrier when it is broken as it is made of wood.
Her latest project is a simple fridge that runs without electricity. 68 There are now thousands of families in villages in Zambia, Namibia and South Africa who use it to keep milk, food and medicine cool.
Emily is now a young woman. She is the winner of several prizes for her inventions. She is so successful. 69 As a great inventor, Emily often visits schools and talks to teenagers.

Paper is one of the most important products ever invented by man. The invention of paper meant that more people could be educated because more books could be printed. Paper played an important role in the spread of knowledge.
Paper was first made in China about 2, 000 years ago. In Egypt and West, paper was not very commonly used before 1400s. Paper was not made in southern Europe until about 1100s. After that, the forestry (林业) countries such as Canada, Sweden, Norway, Finland and the United States became the most important countries in paper-making. Today Finland makes the best paper in the world. And it has the biggest paper industry in the world.
When we think of the paper, we think of newspaper, books, letters, envelops and writing paper. Paper plays an important role in our life.
Paper is also very good for keeping you warm. Houses can be insulated (隔离) with paper. You perhaps see homeless men sleep on a large number of newspapers.

Tim Berners-Lee is not the most famous inventor in the world. However, his invention has changed our lives.
He was born in London, England in 1955. When he was a small boy, Tim was interested in playing with electrical things. He studied science at Oxford University. He made his first computer from an old television at the age of 21.
Tim started working on early computers. At that time, they were much bigger than now. He worked in England then Switzerland. Tim was really interested in two things, computers and how the brain works. How could the brain connect so many facts so quickly He had to work with people all over the world. They shared information about computers. It was hard to manage all the information. He answered the same questions again and again, and it took a lot of time. It was even difficult for computers in the same office in Switzerland to share information. Tim also forgot things easily. Could a computer work like a brain Could it “talk” to other computers
There was an Internet already but it was difficult to use. In 1989, Tim Berners-Lee invented the World Wide Web (WWW) all by himself. This had a special language that helped computers talk to each other on the Internet. When people wanted to share information with others, they used the World Wide Web. The Internet grew quickly after that.
Tim Berners-Lee doesn’t think he did anything special. He says that all of the ideas about the Internet were already there. All he did was to put them together. He says that many other people worked together to make the Internet what it is today.
Most inventors want to become rich. But Tim gave away the World Wide Web for nothing. He now works in America. He helps people share technology and wants the Internet to be free for everyone to use. Maybe he is the most important but least famous inventor in the world today!
