As the old Chinese saying goes, “If you live next to a mountain, you’ll make a living by the mountain; if you live next to the river, you’ll make a 36 by the river. “So many people living along the Yangtze River have caught fish to make money for hundreds of years. However, the government (政府) asked people to 37 fishing from 2020. At the same time, with the help of the local government, they don’t need to 38 losing jobs but live a better life.
Zhu Yicai, a 67-year-old fisherman in Yugan village, made a plan for opening a farmhouse. He bought 39 stones and wood to build a 1,800-square-meter farmhouse and at most 200 people could have dinner together there each time. “Years of protection and the no-fishing rule helped make Yangtze River a 40 place for wild animals. This year, up to 700,000 birds fly here to spend their winter and many visitors come to watch the 41 , and I am making a living by the lake travel,” he said. The new job 42 the family about 1 million yuan last year. The result was so surprising that Zhu 43 thought about it. Zhu also wants to turn the second floor of the farmhouse into a 44 for visitors to sleep and live.
Like Zhu Yicai, many fishermen changed their jobs and more and more people 45 working in travel companies. They not only learn new skills for a better life but also help prevent the river from overfishing (过度捕捞).

Water is very important 56 living things. Without water there can be 57 life on earth. All animals and plants need water. Man also needs water. We need water to drink, to cook food and to clean 58 . Water is found almost everywhere. Even in the 59 part of the world, there is some water in the air. You can not see it 60 feel it when it is part of the air. The water 61 seas, rivers is a liquid. The water in the air is not a liquid 62 a gas. Clouds are made of water. They are little drops of water. When the water 63 , it falls as rain.
Water may be a liquid, a solid, or a gas. When it is a solid, it may be as 64 as ice. When it is a gas, you can not see or feel it.

Melting Ice Sheets
Ice sheets on Earth have been melting, breaking up, and disappearing.
The melting of ice sheets over the past century has contributed to a 10—25 cm rise in global sea 66 . If the Antarctic ice sheets were to break up, it would 67 global sea levels by almost six meters. If both the Arctic and Antarctic ice sheets were to melt, the result would be a sea level rise of nearly 70 meters. And many countries would be under the 68 .
The ice sheet is the largest reservoir of fresh water, holding 70 percent of the world’s fresh water. 69 , the melting of ice sheets means that millions of people will face the threat of earthquakes, floods, droughts and the 70 of drinking water.
Hurricanes and typhoons have become stronger and longer, lasting over the past 30 years due to global warming. The 71 the weather is, the faster ice sheets melt. It’s reported 72 ice sheets may melt completely by 2035.
As is known to all, the melting of ice sheets can make some deadly 73 return, some kinds of animals 74 , and 50 billion tons of methane (甲烷) release. How terrible it is!
What should we do to stop the melting and avoid the happening of disasters
After studying the ice sheets in Qilian Mountains, Chinese scholars pointed out that 75 the natural climatic factors, the other main causes of ice sheets melting were overpopulation, deforestation and overuse of groundwater. Therefore, the population should be controlled, forest and groundwater resources should be protected.

Curiosity is often called the “engine of progress”. It drives humans to explore, discover, and create. From ancient times to the present, curious minds have 96 the world we live in today.
When Isaac Newton saw an apple fall from a tree, he didn’t ignore it. Instead, he felt 97 and asked, “Why does it fall down ” This question led him to 98 the theory of gravity. Similarly, Archimedes was curious about the water rising when he got into a bath. His 99 led to the discovery of buoyancy (浮力), which is still used in physics today.
In daily life, curiosity helps us learn better. A 2014 study 100 that curious people remember information 30% better than others. This is because curiosity makes the brain more 101 to new knowledge. For students, staying curious can 102 them to ask more questions and find answers on their own.
Curiosity also brings joy. Think about how a child 103 hours playing with a toy to figure out how it works. That joy of 104 is the same feeling scientists get when they make a new discovery. Especially, it’s a 105 that keeps us going even when things are difficult.
However, curiosity isn’t just for great scientists. It’s for everyone. Whether you’re 106 how a phone works or why stars twinkle, asking “why” is the first step to learning. As the saying goes, “The important thing is not to stop 107 .”
So, let’s keep our curious minds alive. Ask questions, 108 experiments, and never be afraid to explore. You never know what amazing things you might 109 or how your curiosity could 110 the world.

A curious mind is like a key that can open the door to new knowledge and opportunities. It is the 111 that drives people to explore the unknown, ask questions, and seek answers.
When we are curious, we are eager to learn 112 about the things that interest us. This curiosity can lead us to read books, 113 experiments, or have discussions with others. It makes learning 114 and exciting.
Take Thomas Edison as an example. His curious mind made him 115 in everything around him. He asked questions like “Why does this work ” and “How can I make it better ” These questions 116 him to invent many important things, such as the light bulb.
However, curiosity is not just about being interested in something. It also 117 having the courage to take risks and try new things. Sometimes, the answers we seek may not be easy to find, and we may 118 many difficulties. But with a curious mind, we will not give up easily.
In our daily lives, we should 119 our curiosity. We can start by asking more questions, being open-minded, and 120 new experiences. A curious mind can bring us a more colorful and meaningful life.

阅读下面短文，掌握其大意，然后从各题所给的 A、B、C、D 四个选项中，选出最佳选项。
Last year, my school started a “Green Campus” project to encourage students to protect the environment. At first, I thought it was just a usual activity and didn’t take it seriously. But after joining in several events, I changed my mind completely.
The first event was a “Waste Classification Challenge”. Our teacher gave each class a set of colored bins and taught us how to sort waste into different categories: recyclable, harmful, kitchen and other waste. At the beginning, I often mixed up the bins. For example, I once threw a plastic bottle into the kitchen waste bin. My deskmate, Lily, noticed it and 133 me patiently. She said, “Plastic bottles can be recycled and made into new products. If we throw them away randomly, they will pollute the soil.” Her words made me realize the importance of waste classification.
Later, we had a “Tree-Planting Day” on a weekend. All students and teachers went to a park near our school. We brought shovels, buckets and young saplings. I was in charge of digging holes. It was harder than I expected. After digging three holes, my arms felt so 134 that I wanted to give up. But when I saw my classmates working hard, I kept going. We planted over 50 trees that day. Looking at the small trees standing in a row, I felt a strong sense of achievement.
Another interesting activity was “Second-Hand Market”. Students brought their old books, toys and clothes to sell or exchange. I took some of my old storybooks and a toy car. To my surprise, a little girl was very interested in my storybooks. She 135 me a hand-drawn card in exchange. The card had a picture of a green earth and the words “Protect Our Home” on it. That small card became my favorite gift.
Through these activities, I learned that protecting the environment is not difficult. It’s all about small actions in our daily life, like turning off the lights when leaving a room, using reusable water bottles instead of plastic ones, and 136 waste properly. Now, I always remind my family and friends to live a green life. I even started a small “green corner” in my bedroom, where I grow some small plants.
137 the “Green Campus” project, I found myself paying more attention to environmental protection in every aspect of life. Once, I saw my little brother using a disposable plastic bag to hold snacks. I told him it was bad for the environment and gave him a cloth bag instead. He was confused at first, but I explained patiently and he soon got used to bringing his own bag when going shopping. I 138 get angry when others don’t know how to protect the environment now; instead, I try to explain the importance of eco-friendly life to them gently.
Last month, our community held a “Green Life Sharing Meeting”. I invited my 139 to join me. We shared our experiences of protecting the environment, like how to make homemade plant fertilizer and how to reuse old boxes as storage boxes. Everyone was active in the discussion, and we all 140 new ways to live a greener life from each other.
I also realized that environmental protection doesn’t need 141 actions. Even picking up a piece of trash on the road or turning off a leaking tap is a contribution to the earth. Every small effort adds up, and together we can make our planet 142 .
Yesterday, I found my “green corner” in the bedroom had new sprouts. Looking at the tiny green leaves, I felt happy—this small corner is not just a place for plants to grow, but also a symbol of my growing awareness of environmental protection. I believe that as long as everyone keeps doing these 143 things, our future will be full of green and hope. No one wants to live in a 144 world, so let’s keep working for a better environment together.

Water is the most precious resource on our planet. It covers about 71% of the Earth’s surface, with approximately 97% being salt water in oceans and only 3% being fresh water. This fresh water exists in different forms: about 68% is trapped in glaciers, 30% is underground, and just 2% is found in rivers, lakes, and the atmosphere.
The continuous movement of water on Earth is called the 145 . This natural process begins when the sun’s heat causes water to 146 from oceans, lakes, and rivers. The water vapor rises into the atmosphere where it cools and 147 into tiny droplets, forming clouds. When these droplets become too heavy, they fall back to Earth as precipitation (降水), which could be rain, snow, or hail depending on the temperature.
Water is essential for all 148 processes in living organisms. Humans can survive without food for weeks, but can only live 3-5 days without water. Besides drinking, we use water for agriculture, which consumes about 70% of global fresh water. Industries also require large quantities of water for 149 and cooling purposes.
However, water resources are under threat. Many areas face 150 due to climate change and overuse. Pollution from factories and farms has made many water sources 151 . In some developing countries, millions of people lack access to 152 drinking water, leading to waterborne diseases.
To address these challenges, we must take action. Simple measures like fixing 153 pipes can save thousands of liters annually. Using 154 appliances and practicing rainwater harvesting are other effective solutions. Governments should also invest in water treatment plants to ensure clean water for all.

Artificial Intelligence (AI) is one of the hottest topics at China’s annual “Two sessions” (两会) this year. Many representatives (代表) agree that AI brings exciting changes to our lives, but they also worry about its 155 . Let’s take a closer look at why AI is both helpful and worrying, and what China plans to do about it.AI’s Good Side and Bad Side
First, AI such as Deepseek is a powerful 156 . It helps people work faster, makes fun videos, and even helps 157 in hospitals. However, some people misuse AI to cheat others. For example, AI face-swapping (换脸) can make unreal videos or recordings. A 65-year-old woman loses 2 million yuan because she believes an unreal video of a famous actor, Jin Dong. The 158 Jin Dong asks her to “help” him make a movie. Similarly, unreal videos of Lei Jun, the founder of Xiaomi, also cause trouble. The stories of Jin Dong and Lei Jun show how 159 AI can be if used wrongly.Calls for Stronger Rules
During the meetings, representatives suggest new laws to stop 160 AI use. Lei Jun, the Xiaomi founder, says, “We need 161 laws for AI and must teach people how to use it safely.” Actor Jin Dong says, “We need more rules to stop people using AI for 162 .” Another representative, Chen Da, says the 163 of protecting children and the old, because they are often easily cheated (欺骗).China’s plan for AI
The Chinese government (政府) is taking action now. They make rules to help AI grow 164 . These rules ask AI companies to check their products carefully.A Safer AI Future
Experts believe three things can help: better laws, smarter technology, and teaching people. For example, schools can teach students how to 165 out unreal AI videos. Technology companies can design tools to find out AI cheating. And parents should also 166 their children about the potential risks of AI.Conclusion
AI is like fire — it can cook food or burn a house. In a word, AI is the future, but we must use it 167 . Only in this way can we make sure AI brings more good than 168 to our society. Moreover, everyone 169 to realize new challenges that come with AI. We should work together to make the most of AI while minimizing its negative impacts. In the future, with proper operation, AI will surely bring us more convenience and progress.
