Tianzhu Mountain in China is famous for its high cliffs (悬崖) and amazing sights. But keeping this mountain clean is not easy. Tourists throw rubbish on the cliffs. Every day, a group of workers pick up the rubbish. They are famous as the “cliffside cleaners”.
Tu Yousheng is one of them. He started to work here over 20 years ago. Every morning, he uses safety ropes, takes a rubbish bag, and climbs down the cliffs. The wind is strong and the rocks are huge, but he carefully picks up every piece of rubbish. Sometimes, rubbish gets caught between rocks. He has to work hard to pull it out.
Tu grew up near Tianzhu Mountain. He loves it like his home. “This job is ________, but someone has to do it,” he says. Over 20 years, Tu has climbed 2,800 km—as far as from Beijing to Urumqi! His team works in hot summers and cold winters but never stops.
Besides (除了) cleaning, Tu also teaches tourists about taking care of nature. When he sees tourists litter, he never shouts at them. Instead, he kindly asks them to stop and explains why it is important to keep nature clean. Many visitors listen to him and even offer (主动) to help clean up.
Thanks to these cleaners, Tianzhu Mountain stays beautiful. Their hard work reminds us to care for nature. Next time you travel somewhere, remember not to drop litter.

The Bottle School Project is an amazing environmental initiative. These schools are built using plastic bottles filled with packed sand. This construction method is not only eco-friendly but also very practical. The bottle walls provide excellent insulation, keeping classrooms cool in hot weather and warm in cool weather.
This innovative idea helps solve two problems at once. First, it reduces plastic waste by reusing bottles that would otherwise pollute the environment. Second, it provides affordable school buildings for communities that need them. The bottles are free, and local people can help with the construction, making it a community project.
Students who attend these schools learn about environmental protection through their own school building. They see firsthand how recycling can create something useful and beautiful. This practical lesson in sustainability is just as important as their academic lessons.

Do you know a mountain that looks like big steps
That’s Batai Mountain, an amazing place in Dazhou, Sichuan.
The name “Batai” means “eight terraces (台阶)” because it looks like it has eight huge flat steps going up. It’s very tall (over 2,200 metres). Because it’s so high, it’s one of the first places in Sichuan to see the sunrise each morning. Watching the sun come up from the top is amazing.
For nature lovers, Batai Mountain is a good place to visit. You can see fantastic deep valleys, interesting rock shapes, and big forests all around. On the fine mornings, there are thick (厚的) clouds covering the land below, making the tops of the mountain look like islands in a huge white sea. And if you’re brave enough, you can even walk on special paths (小路) with glass parts high above the ground—it feels just like walking in the sky.
Batai Mountain is a natural geopark (地质公园) protected by the government. It’s a very important and beautiful place. Whether you like hiking, taking amazing pictures, or just seeing cool natural sights, Batai Mountain is an unforgettable place to visit. It’s Dazhou’s natural wonder.

Water is one of the most useful substances in our lives. We use water to drink, bathe, cook. Plants and animals need water to grow and live. At a factory, water helps to make chemical products and cool machines. At home, we put water in the dishwasher to wash dirty plates and cups. In the countryside, farmers pour water on fields to help crops like rice and cotton grow. We also use water for fun — at the swimming pool or water park. Water can shine like a mirror on a corner of a calm river. Water can be boring too — it waits in a glass or a pot without any movement. In cities, wastewater goes to a treatment plant before it returns to rivers. This clean-up step is very important. People do research on ways to save energy, use water fully, and make energy-saving systems. We must raise awareness about saving water, because fresh water is limited. Everyone can agree: water is precious. If we don’t value it, we could face a problem — a lack of safe water. So let’s act carefully: fix leaks and shut taps. Only in this way, can we protect our water and our future.
19．The passage says we use water to do all of the following EXCEPT:
A．Cook food. B．Wash clothes. C．Take a shower. D．Wash dishes.
20．According to the passage, where does wastewater go before returning to rivers
A．To the ocean. B．To homes. C．To a treatment plant. D．To factories.
21．The word “precious” in the last paragraph probably means:

阅读短文，从所给的选项中选出可以填入空白处的最佳选项，其中有一个多余的选项。
Numbers in different countries may have different meanings. 25 Take “8” for example. The Chinese pronunciation (发音) of number “8” has almost the same sound as that of the Chinese character “发”, which means making plenty of money. 26 They believe that the number will bring them more money.
27 They think such an idea is ignorant (愚昧的) and superstitious (迷信的). A number is one thing, and good luck is another. As for me, I agree with the second idea. Clearly, lucky numbers are only a kind of superstitious belief. Perhaps it holds true for some cases, but often it does not. Numbers can never bring good luck to a person at all and our luck is in our own hands. 28 Let’s always remember “Chances are only for the prepared mind.” and “No pains, no gains.”
A．In fact, different people have different lucky numbers.
B．So, everyone can have good luck only if he tries his best.
C．In China, some people think that some numbers bring them good luck.
D．However, others don’t believe that numbers have anything to do with good luck.
E．So, many Chinese people hope to get their phone numbers or car numbers to include this number “8”.

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.

All of us face problems. Unfortunately, we don’t always know how to solve them. Our usual solutions may not work in every situation. That’s why we need to think creatively to come up with creative solutions. We may not consider ourselves creative people, but if we can improve our creative thinking, new ideas will emerge. The following are some ways to boost your creativity.
First, be curious. Don’t take for granted what we do or use every day. Think about how to do things differently. Sometimes the best ideas come from combining old ideas or changing them slightly. Second, avoid being immediately critical. When we think of a new idea, write it down—and save it. ________
In addition, ask “what if”. Instead of just accepting what we know as reality, asking “what if” may help us come up with new ideas. Then, take some time to relax. When we are not making any headway with our problem, we stop working on it and do something completely different. We may come back to the problem with a fresh outlook and a new way to solve it. Try some of these ideas, and you’ll find that being creative isn’t so hard at all!

Curiosity is like a magic key that helps children unlock the doors to knowledge and growth. During childhood, asking questions such as “Why is the sky blue ” or “How do birds fly ” shows a natural desire to explore the world. This curiosity drives learning and shapes their development in amazing ways.
First, curiosity improves learning. When children are curious, their brains become active in searching for answers. For example, a child who wonders how plants grow might read books, watch videos, or even plant seeds to observe the process. This hands-on experience helps them remember information better and builds critical thinking skills.
Second, curiosity encourages creativity. Curious kids often try new activities or solve problems in unique ways. Imagine a child experimenting with building blocks: they might fail many times, but each attempt teaches them something new. Over time, they learn to think outside the box and develop creative solutions.
Also, curiosity helps children face challenges. Life is full of unknowns, but curious minds see challenges as adventures. Students struggling with math might ask questions, seek help, and practice until they succeed. This builds confidence and resilience.
To support children’s growth, parents and teachers should encourage questions, provide learning resources, and let them explore safely. Remember, curiosity is not just about finding answers—it’s about enjoying the journey of discovery. By nurturing curiosity, we help kids become lifelong learners and creative thinkers.
In short, curiosity lights the path of growth. Let’s protect this precious gift in every child!
56．What is curiosity compared to in the article
A．A treasure map. B．A dark night.
C．A magic key. D．A mystery box.
57．Which question does the article mention as an example of children’s curiosity

In the past you could draw anything you wanted on a computer screen and then print it out on a piece of paper—a flat piece of paper. But imagine being able to print something that is three-dimensional—3D．Would you like to design an object, such as a cup or a toy, and then “print” it out Well, there is the technology to help you do this—to produce even a whole house!
3D printers might be the size of a suitcase or even a small room, depending on the object they are made to produce. You make a 3D design on your computer and send it to the printer. Inside the machine, the object you have designed is made as one object.
So how is this being used In medicine, 3D printing is often used to make teeth. The dentist takes a 3D image, something like a photo of the real tooth and a new one is printed in that exact shape. Then you might also want to print a mobile phone cover or a special pair of shoes.
Scientists are taking this even further. They have made a bicycle that just needs a chain and two tires (轮胎). Car parts have been made for a while, and now they are even making a body of a whole car!
But imagine how printing a whole house might help people build houses. A Chinese company has made houses using a giant 3D printer. They use a mixture that includes concrete (混凝土) and recycled building waste.
This is a good thing, as it helps the environment. They believe that their method of printing houses is cheaper, faster, less dusty and less noisy than the ordinary way that houses are built.
It seems that 3D printing technology will change our world, and China is leading the way.
66．3D________ enables you to “print” out many objects you design on your computer.
A．screen B．product C．paper D．technology
67．The size of a 3D printer might be________ according to the object they design.

C．photos D．mobile phone covers
69．Scientists are taking this even further. Here “this” probably refers to “________”.
A．a pair of shoes B．the printing
C．a new bicycle D．a whole car
70．Which of the following can be the best title for this passage
A．Use the 3D printing technology to build houses.
B．China is now ready to produce 3D printers.
C．The 3D technology will change our world.

Imagine you are in a field at night, and suddenly, you see lots of little lights around you. You have just found a gathering of fireflies, and their twinkling lights are like a secret language. This nighttime lights show, especially in the forest, has fascinated people for a long time. Let’s explore the mystery of fireflies.
Did you ever wonder how fireflies make their tails glow The special power of fireflies to make light is called bioluminescence (生物发光), a special ability that some animals, like fireflies, have to create their own light through a chemical reaction. It happens when two chemicals in their bodies combine (结合) and generate a chemical reaction that produces light.
However, why do fireflies need to make light in the dark Now, imagine you are a firefly looking for someone special in the dark. How would you find Mr. or Ms. Right Fireflies use their glowing lights to send “hello” messages to each other. Each kind of firefly has its own special pattern of flashes, like a secret code. They use their lights as an invitation to get to know each other better, so that they can mate and produce the next generation of fireflies.
But fireflies do not just use their lights for conversations. They also use them to stay safe. Imagine you are an adult firefly in the shadows, and a big spider is trying to catch you. What do you do You turn on your light! Your bright glow is like a sign that tells the spider “I taste disgusting. Do not eat me!”
This story of fireflies tells us how amazing and wonderful the natural world is. Exploring the world of fireflies helps us see how important it is to take care of nature and all its fascinating organisms (生物), no matter how small they are.

A Curious Boy’s Discovery
Tom was a very curious boy. He loved to explore the woods near his home. One day, while walking in the woods, he noticed some strange-looking plants. They had big, colorful leaves and small, shiny fruits.
Tom was very curious about these plants. He had never seen anything like them before. He picked one of the fruits and examined it carefully. It smelled sweet, but he was not sure if it was safe to eat.
He decided to take some of the plants home to show his father. His father was a botanist, and Tom thought he could tell him what the plants were. When Tom showed the plants to his father, his father was very excited. He told Tom that these were rare plants that were not commonly found in that area.
His father explained that the plants were important for the ecosystem. They provided food and shelter for many small animals. He also told Tom that it was important to protect these plants and not to pick them without permission.

No matter how you do it, booking holidays can be a headache. It used to need a visit to a travel agent (旅行代理人)… Later, online travel agents showed up, allowing people to plan trips from the comfort of their own homes. Now, they are promising to handle the brainwork, too, with the help of AI. Expedia, for example, has introduced Romie, its “ AI-powered travel buddy (伙伴). ” has brought out TripGenie.
Many people want AI to save them from boring tasks. This may explain why AI trip planners are drawing attention. They’re perfect for those who go mad when booking holidays.
But are these AI booking agents reliable (可靠的) Some have tried them out. When a couple asked TripGenie to find a romantic (浪漫的) hotel in Paris, its top suggestion was by the airport. Well, perhaps the AI agent is still in its early days, they said.
Tools like TripGenie are facing competition from AI companies, too. OpenAI, for example, is testing its system. The AIbot is designed to “mimic (模仿) a human’s use of the Web.” When asked about that Paris trip, it suggests places with a view of the Eiffel Tower. Some researchers think OpenAI might soon change the online travel agents’ market.
________. Air Canada got in trouble after its chatbot wrongly promised a user a discount (折扣). Could AI agents be fooled into booking a more expensive flight Would anyone feel safe giving his or her credit card information to an AI agent then
AI agents may also have difficulty understanding the endless variety (不同种类) of people’s tastes. Not everyone finds an expensive view of a metal tower romantic. One couple—the groom (新郎) Icelandic and the bride (新娘) French—recently got married on a flight between their countries. A hotel room by Paris Charles de Gaulle Airport might have suited them better.
81．Why does the author say “booking holidays can be a headache” in paragraph 1
A．Because it is always expensive.
B．Because it used to need going to a travel agent and now there are too many choices.
C．Because AI is not helpful at all.
D．Because people don’t like to travel.
82．What is Romie
A．An AI-powered travel helper from Expedia. B．A travel agent from .
C．A new airport in Paris. D．A chatbot from OpenAI.
83．Which of the following can be put in ________
A．Planning a trip is very popular now
B．Some users worry about slow replies from AI booking agents
C．AI booking agents can help us get cheap tickets
D．One problem with AI booking agents is that they make mistakes
84．The writer talks about the couple who married on a plane in the last paragraph to show that ________ .
A．airport hotels are usually very romantic
B．flying between countries is a good way to travel
C．TripGenie’s suggestion is reliable
D．different people may have special needs that AI doesn’t understand

How Students Can Practice Environmental Protection
With the development of the world, environmental problems have become more and more serious. As students, we have a responsibility to protect the environment. There are many simple ways we can practice environmental protection in our daily lives.
First, we can save paper. Every year, a large number of trees are cut down to make paper. We can use both sides of a piece of paper when doing homework or taking notes. We can also reuse old notebooks by using the blank pages. In addition, we can send e-mails instead of writing letters to our friends, which can save a lot of paper.
Second, we can save electricity. We should turn off the lights, computers and air conditioners when we leave the classroom or our rooms. We can also use energy-saving bulbs, which use less electricity than ordinary bulbs. During the day, we can open the curtains to let in natural light instead of turning on the lights.
Third, we can reduce waste. We can bring our own shopping bags when going shopping instead of using plastic bags. Plastic bags are harmful to the environment because they take a long time to decompose. We can also separate our waste into different categories, such as recyclable waste and non-recyclable waste. This makes it easier for workers to recycle the waste.
Finally, we can plant trees. Trees can absorb carbon dioxide and release oxygen, which is good for the air. Every spring, many schools organize tree-planting activities. We can take part in these activities and plant more trees in our community.
Protecting the environment is not a difficult task. It requires our efforts every day. If every student can do a little bit for the environment, we will have a better world.
92．Why should we save paper according to the passage
A．Because paper is expensive. B．Because a lot of trees are cut down to make paper.
C．Because we don’t have enough paper. D．Because paper is not easy to use.
93．What can we do to save electricity
A．Use ordinary bulbs instead of energy-saving bulbs. B．Keep the lights on when we leave the room.
C．Use natural light during the day. D．Keep the air conditioner on all day.
94．Why are plastic bags harmful to the environment
A．Because they are too expensive. B．Because they take a long time to decompose.
C．Because they are not easy to carry. D．Because they are not strong enough.
95．What can trees do for the environment
A．They can absorb oxygen and release carbon dioxide.
B．They can absorb air and release water.
C．They can absorb water and release air.
D．They can absorb carbon dioxide and release oxygen.
96．What is the main idea of the passage
A．Environmental problems are very serious.
B．Schools should organize more activities.
C．Students can practice environmental protection in many simple ways.
D．We should plant more trees.
