An encyclopaedia is a useful special reference book, or a set of books. It contains valuable information on many different subjects, or it can focus deeply on one subject. For over 2,000 years, encyclopaedias have summarized human knowledge to help people learn.
The word “encyclopaedia” comes from ancient Greek words meaning “all-round education”. At first, it described a complete system of learning. A German writer, Paul Scalich, was the first to use “encyclopaedia” as the actual title for a book in 1559. Before that, these books often had creative names or were simply called “dictionaries”. Denis Diderot later made “encyclopaedia” more popular with his well-known French “Encyclopédie”.
The meaning of “encyclopaedia” has changed greatly. Today, people usually think of a large set of books. These books often include maps, pictures, and an index to help find information. They cover many various topics, including biographies of important people, both in the past and at present. Many experts write these articles, and skilled editors carefully put them together.
However, encyclopaedias weren’t always exactly like this. In the past, some were just a single book written by one person, while others were indeed huge sets. They didn’t always have illustrations or information about living people. Arranging topics alphabetically or using languages other than Latin took many years to become very common.
Encyclopaedias can cover all knowledge or focus on specific broad areas, like history or science. They are important because they record what people knew at different specific times. Even old encyclopaedias are valuable because they contain writings from many great thinkers and leaders, showing how our understanding of the world has greatly grown.
1．What is the main purpose of an encyclopaedia
A．To replace formal education systems. B．To advertise new scientific discoveries.
C．To entertain readers with creative stories. D．To summarize human knowledge for learning.
2．How did early encyclopaedias differ from modern ones
A．They focused only on science. B．They were always written in Latin.

C．A newspaper article on modern technology. D．An educational magazine on knowledge tools.
A city without cars would be very strange, right But Venice is such a city. Venice is in the northeast of Italy. It wasn’t built on land, like Beijing or Shanghai, but on more than 110 islands. 6
Even so, travel isn’t difficult. The waterways have always been the best way to get around. There are many waterways and more than 400 bridges that can guide you where you want to go. 7 They like to enjoy the scenery and cool summer nights while taking boat trips. They can talk to other people as they go along.
Venice grew out of small islands in saltwater lakes when some people escaped from a war many years ago and built homes there. 8 Once, people used too much underground water. This made the city get lower little by little. 9 Another problem is the rising seawater. The temperature has risen over the years. 10
Every year, the high water hits the city. When a lot of water comes, more than half of the city is underwater. Scientists are trying different ways to stop the city from getting even lower.
A．Water makes the city special, but it is also a big problem.
B．This has made the ice of the Arctic Ocean melt.
C．Seawater is everywhere around the city.
D．Now the city has gone down by more than 20 centimetres.
E．People in Venice move from place to place by boat.
Albert Einstein (1879—1955)
Early Life
Albert Einstein was born in 1879 in Germany. He had been an extraordinary person since he was born. He was always interested in things around him and full of imagination. He loved watching things carefully and asking a lot of questions about them. His questions were often hard to answer for teachers.
Schooling
Einstein started school in 1885. He did well in Maths and Science. Einstein finished grammar school in Germany and entered a university. He graduated (大学毕业) with the subject teacher diploma for Maths and Physics in 1900.
Scientific Work
After graduation, Einstein worked at the Swiss Patent Office. He spent much time studying physics. By 1909, Einstein had become a top scientist. Though he became successful in the field of science, he still worked hard on scientific research. Finally, he was awarded the Nobel Prize for Physics for the year 1921.
Later Life
Einstein kept doing his research until he died in 1955. Scientists studied his brain after his death to see if there was anything special about it. However, there was no answer.
Today, many famous scientists still think Einstein is the smartest man in the world.

Ants have the ability to smell out cancerous cells (癌细胞) in humans, which has been found by a study, suggesting that they could be used to find the cancer in the future. Scientists from The French National Center for Scientific Research (CNRS) found that some ants have a good sense of smell. “But more tests must be carried out before they could be used in hospitals,” the team said.
The scientists did tests with 36 ants, smelling cells in the lab. First, they let the ants smell some cancerous human cells. Every time the ants smelt cancerous cells, they were rewarded with sugar solution (糖溶液). In the second step, the ants were put into two different smells. One was a new smell of healthy cells and the other was still the smell of the cancerous cells. Once the ants found the cancerous cells successfully, the researchers made them smell different cancerous cells. As such, the scientists found that ants could tell between cancerous and healthy cells and between two cancerous cells.
This isn’t the first time that scientists have used the animals’ sense of smell to find cancerous cells. “Dogs are good at finding something with their noses. However, training dogs to do so needs several months or a year. On the other hand, ants can be easily raised in a short time. They are inexpensive, and hundreds of them can be trained with fewer times,” scientists pointed out.
“This study shows that ants are able to learn very quickly. The way can be used for other tasks including finding danger or other illnesses,” scientists added.
16．What can we know from CNRS’s study
A．Ants help humans keep off cancer. B．Dogs are used to find people with cancer.
C．Ants are able to smell out cancerous cells. D．Ants work better than dogs to find cancer.

A．①②③ B．①②④ C．①③④ D．②③⑤
18．What’s the writing purpose (目的) of the text
A．To introduce ants that will be more useful than we imagine.
B．To teach people to protect ants from now on.
C．To show ants and dogs are both humans’ friends.
D．To explain why ants are more important than dogs.

Numbers are important in our daily life. 24 Here are some examples of them.
Some problems are difficult to work out, but there are a lot of sayings about numbers that can help. 25 We know that two heads are better than one. It is always better to work with another person to work out a problem.
Sometimes we can kill two birds with one stone. 26 But we must remember that two wrongs don’t make a right. If someone does something bad to you, you should not do the same to him.
If you are going out with your girlfriend or boyfriend, you do not want another friend to go with you. 27
When I was a child in school, I had to learn the three Rs. These important skills are reading, writing and arithmetic (算术). 28
These are some expressions about numbers. Hope they can be useful to you.
A．That is to say, we can complete two things with only one action.
B．We not only use numbers to count things, but also use them to show different meanings in our language.
C．These three words do not all start with the letter “R”, but they have the sound of “R”.
D．For example, if we put two and two together, we might come up with the right answer.
E．You can just say to your friend: Two’s company, three’s a crowd.
Many Chinese idioms contain numbers, such as caigao badou (才高八斗) and banjin baliang (半斤八两). Why do they have something to do with numbers
A talented person
The idiom caigao badou is used to describe a talented person. It is based on a story about Cao Zhi (192-232), the younger son of Cao Cao (155-220), a warlord (诸侯) who lived during the Three Kingdoms period.
Cao Zhi was one of the best poets of his time. Besides his poetry, his fu (赋) was also excellent. His works, such as Luoshen Fu (《洛神赋》), are full of beautiful descriptions.
Xie Lingyun (385-433) was a famous poet who lived during the Eastern Jin Dynasty. He was quite proud of his own writing, but also admired Cao Zhi’s talent. He once said to others: “Heaven only gave the world one dan of talent, and Cao Zhi alone had eight dou. I deserve (值得) one dou, and all the other poets should share the last one dou.”
The dan used was an ancient Chinese measurement for grain. One dan is equal to 10 dou. The idiom can be translated into “eight bushels of talent” in English.
Standing tall
In China, people often say “standing like a 7-chi-tall man”（堂堂七尺男儿). How tall exactly is a 7-chi-tall man
When people say qichi naner (七尺男儿), they’re usually referring to a man who is tall and strong. However, it’s not easy to tell exactly how long seven chi is. As a traditional Chinese unit of length, the measurement of chi has changed often over time.
In earlier times, such as the Shang Dynasty (16th century-11th century BC), one chi was about 16 cm. So seven chi would be equal to about 110 cm. A 7-chi-tall man at the time would be a little person.
When it came to the Three Kingdoms period (220-280), one chi became longer and reached 24.2 cm. So seven chi would be about 170 cm, an average height today.
In the following dynasties, chi kept growing longer. It became about 30 cm in the Tang Dynasty (618-907) and finally 35.5 cm in the Qing Dynasty (1644-1911). It means that a 7-chi-tall man would be 248.5 cm. That would be a real giant!
Same difference
The idiom banjin baliang (半斤八两) means “same difference”.
One jin and eight liang used to be the same. Chinese people measured weight differently in the past. At that time, one jin (500 grams) was made up of 16 liang. So half of one jin was eight liang.
People used a steelyard balance (杆秤) to weigh things. It had 16 gradations (秤星) on its arm. Each gradation stands for one star in the sky. The 16 gradations stand for 16 stars – the Big Dipper (北斗七星), Sagittarius and the stars of fortune, prosperity and longevity (福禄寿星).
It was said that if you cheated someone while trading, you would lose the blessing (庇佑) of these stars. This helped to keep people honest while trading.
After 1949, China started to do more international trade. To make things easier, we changed 16 liang for one jin into 10 liang for one jin.

32．Which of the following statements is not right
A．The idiom “caigaobadou” usually refers to a talented person.
B．In ancient China, Dan only referred to how much talent a person had.
C．The idiom “7-chi-tall man” usually refers to a man who is tall and strong.
D．Before 1949, banjin weighed the same as eight liang.
33．How did the belief in the stars help keep people honest while trading

B．People who cheated others would gain the blessing of the stars.
C．People who cheated others would become wealthy.
D．The belief in the stars did not affect people’s honesty while trading.
Do you know ChatGPT It’s an artificial intelligence (AI) tool. It can answer questions, tell stories and write articles. But it’s very “thirsty”, said a new study from Harvard University.
ChatGPT has “homes” around the world in data centres (数据中心). When it works, the computers in the data centres get very hot. Workers then have to use water to cool them down. Cold water goes into pipes near the computers. The water needs to be very clean. They can’t use seawater because it can eat away the pipes.
When you ask ChatGPT 50 questions, it “drinks” 500 millilitres (ml) of water. Scientists used about 700,000 litres of water to build ChatGPT. The water use is very big. People can make 370 cars with the water.
ChatGPT is just one of the AI tools around the world. You need data centres to do everything on the internet. There are more than 8,000 data centres around the world. The number is still growing.
AI uses a lot of water to “grow”. The world’s water may not be enough. Many people don’t have enough water to drink. But AI technology helps people. Should we rethink how we use AI

To celebrate a breakthrough (突破) by students in using AI to change silkie chicken (乌骨鸡) farming at the chicken farm in Chishui, Guizhou Province, the Tencent Cloud Artificial Intelligence Class—a programme set up by the university and Tencent—offered free “AI chicken soup” to all teachers and students at Shenzhen University on 16 January, 2024.
“As the Spring Festival is on the way, the farm in Chishui sent hundreds of chickens and eggs to the university, so we decided to turn these chickens into ‘AI chicken soup’ before the holiday to give teachers and students a taste of technology,” said Chen Sirui, a student in the class.
Over eight months, about a dozen students from the class have tried to dedicate themselves to developing the silkie chicken farming in Chishui. They used the computer vision technology to successfully identify (识别) and track (追踪) 250,000 silkie chickens. The result was a success of the world’s first intelligent silkie chicken farming system. Operating for more than six months, the system increased the farm’s output by 30%, keeping another 60,000 chickens.
Class member Chen said, “This system sends valuable data to the chicken farmers’ mobile phones. The farmers can notice their chickens at any time. The aim is to raise the income of the farmers.” A leader of the university said, “The project enables students to face real industry challenges, deepens their understanding of technology and develops their practical skills.”

Lots of people go travelling during holidays. As travellers look for more personalized (个人特制的) experiences, many choose AI to be their online tour guides.
During the May Day holiday, Wu Hongbo, a visitor from Dalian, travelled to Shanxi. It was his first visit to Shanxi. Wu didn’t want to join a tour group because he would have to spend a lot of money and he couldn’t explore freely. There were so many places of interest in Shanxi and he was not familiar with the travel routes (路线), so he turned to AI for help.
Wu used AI to plan a fantastic tour of Shanxi. He input the places he wanted to visit, his travel dates, budget and personal interests into an AI app. Soon, he got a personalized week-long travel plan. It showed him the ways to get around, places to visit, and hotels to stay in. Wu is interested in ancient buildings and tasty food, so the AI app also listed several not-so-famous but culturally rich places and delicious dishes.
“This AI-planned tour truly gave me great surprises,” Wu said. “The places and routes perfectly matched (与……一致) my taste, helping me understand Shanxi better.”
Specialists believe 2025 will be the breakout year for AI tour guides. They think AI can meet tourists’ needs for personalized travel. During a personalized trip, AI can serve tourists in real time. Through modern technologies, an AI tour guide can act like a personal guide, explaining the historical stories and cultural meanings behind the tourist areas.
In the future, AI tour guides will help human (人类的) guides and together they can bring a more personalized experience to make travel more exciting.

On Wednesday, People’s Liberation Army (PLA中国人民解放军) of China showed all five types of its newest fifth-generation fighter jets for the first time at a big military parade (阅兵) in Beijing. This was to mark the 80th anniversary (周年纪念日) of the victory (胜利) in the Chinese People’s War of Resistance (反抗) Against Japanese Aggression (侵略) and the World Anti-Fascist (反法西斯) War.
The planes — J-20, J-20A, J-20S, J-35A from the Air Force, and the Navy’s J-35 — flew over Tian’anmen Square in formation. The parade lasted 70 minutes.
This was the first public appearance of the J-20S (the world’s only two-seat stealth fighter), the J-20A (an improved J-20 with a more powerful engine), and the J-35 (the Navy’s first stealth (隐形的) plane).
Fu Qianshao, an aircraft expert, said the J-20S has two seats: one for the pilot and one for an operator who controls electronic equipment or helps with attacks.
The J-20A has a bigger spine, a new nose, and better air intakes for its new engine. This engine is more powerful and helps the plane fly better.
The J-35A is another new stealth fighter. It can control the sky and attack land or sea targets.
Wang Mingzhi, an Air Force researcher, said the J-20 series and J-35A will work together in future battles.
The Air Force also showed a new version of the Y-20 transport plane — the Y-20B．It has new Chinese-made engines that are stronger and use less fuel. This allows the PLA to carry supplies farther than before.
Several new combat drones (无人机) were also shown in the parade. This suggests the Air Force may use more drones in the future.
Wu Peixin, an aviation expert, said many countries are now using stealth fighters together with drones. “Stealth jets are expensive and advanced, while drones are cheaper. In battle, a pilot can guide drones to attack targets without taking big risks,” he said. This new way of fighting could change air combat in the future.
67．Why did the PLA display the fifth-generation fighter jets at the parade
A．To celebrate Army Day.
B．To mark the 80th anniversary of the victory in the War of Resistance.
C．To test their new equipment.
D．To train new pilots.
68．What is a key improvement of the J-20A compared to the basic J-20
A．It has more weapons. B．It can carry more people.
C．It is cheaper to produce. D．It has a new engine and improved design.
69．According to Wu Peixin, what is the advantage of using drones together with stealth fighters
A．Drones are more fun to watch.
B．Drones are cheaper and can be used in risky situations.
C．Drones can replace pilots completely.
D．Drones are faster than stealth fighters.
Prince Mathew is a ten-year-old inventor. He built a model for a robot that will let people do farm work remotely (远程).
When Prince was a young boy, he didn’t share the same interest as the others. He didn’t have many toys at home and seldom played computer games. However, he was interested in playing with blocks to build things whenever he could.
One day, Prince’s mom said that there was not enough space in their apartment to grow all her plants, so he started thinking about ways to solve the problem. Then an idea came up, “What if we could grow plants in a different place from where we live ”
Prince spent about two to three months building his robot. Before drawing out designs, he had to search for a great deal of information on the Internet. In order to build the robot successfully, he went to the market to buy necessary parts. The robot had everything to help it move around. The last step was doing all the coding (编程) to get the robot to be useful and not just a model. His robot was named GrRobot. It had a camera for live video and a basket to plant seeds. It could decide whether to open the sprinkler (喷洒器) according to the soil conditions. All of these will help farmers do farm work and even some difficult work.
Besides this robot, Prince had also invented a game and apps. When asked about the secret to his achievements, he replied, “Seeing people’s lives getting better because of my inventions lets me feel great. I’ll do what I can to solve more people’s problems. And the world may be different with my help.”

Good morning, everyone! My name is Kasper and I’m a child-sized robot. I have black hair and always wear a baseball cap.
I am able to move my arms and head. I can also open and close my mouth and eyes. I can even show several basic emotions, such as happiness, sadness and surprise. For example, I smile when I am happy and I frown when I am sad.
I was designed by scientists in 2005. My job is to help children with autism (自闭症) understand emotions and language and know how to get along with people. I am now working in a kindergarten for autistic children. I talk and play with the children about ten minutes once a week. I often speak slowly to them so that they can better understand what I am saying. I like being touched by these children. However, if a child hits me, I will hide my face in my hands and cry out, “Ouch! This hurts.” The child will then know it is wrong to hit others.
You might ask if I have really helped the children learn some social skills. The answer is “YES”. I remember a girl in the kindergarten. She was alone and protected herself by talking with nobody, but now she is willing to hug everyone and has made some friends after playing with me for some time.
As a robot for autistic children, my greatest wish is to become more helpful to them. I believe that scientists will help make my wish come true in the future.

The Story of a Young Inventor
16-year-old Li Ming is a middle school student from Shanghai. He is not only good at his lessons but also has a strong interest in inventing things. Last year, he invented a “smart trash can” which won first prize in a national invention competition.
Li Ming got the idea of inventing the smart trash can from his daily life. He noticed that his parents often forgot to take out the trash, which made the house smell bad. He also found that some trash cans were not clean and easy to attract insects. So he decided to invent a trash can that could solve these problems.
The smart trash can has many special functions. First, it can send a message to the owner’s phone when it is full. This reminds the owner to take out the trash in time. Second, it has a built-in sensor. When someone walks near it, the lid of the trash can opens automatically, so people don’t need to touch the lid with their hands. This keeps the trash can clean and hygienic. Third, it has a small fan inside which can reduce the bad smell.
Inventing the smart trash can was not easy. Li Ming spent three months doing research and collecting information. He also asked his science teacher for help. His teacher taught him how to use some tools and software to design the trash can. There were many difficulties during the process. For example, the first sensor he used didn’t work well. He tried different sensors and finally found the right one.
Li Ming’s invention has been praised by many people. A company even offered to buy his invention, but he refused. He said, “I want to improve the smart trash can further. I hope it can be used in more families and help more people.”
Li Ming’s story tells us that everyone can be an inventor. As long as we pay attention to our daily life and keep trying, we can create useful things.

D．Because he wanted to make money.
85．What function does the smart trash can have
A．It can send messages to the owner’s phone. B．It can walk by itself.
C．It can cook food. D．It can clean the house.
86．How long did Li Ming spend doing research and collecting information
