Fill a glass almost to the top with room-temperature water. Step 2. Pour 2 tablespoons (汤匙) of oil into the other glass. Step 3. Add 2 drops of food coloring to the glass with oil. Step 4. Stir (搅动) to mix the oil and the food coloring using a fork. Stop once you break food coloring into smaller drops. Step 5. Pour the oil and the food coloring mixture into the glass with water. Step 6. Now watch! The food coloring will slowly go down in the glass, with each droplet expanding outwards as it falls. Looks like fireworks. How it works: Food coloring dissolves (溶解) in water, but not in oil. So when you pour in your food coloring/ oil mixture, the oil will stay at the top of the water because it is less dense (密集的), and the food coloring will begin to dissolve once they go down through the oil and into the water. ( )11. How many kinds of materials do we need for this Water Firework experiment? A. Four. B. Five. C. Six. D. Seven. ( )12. If we _________, the effect of the final experiment will be affected, too.

With its famous snowman mascot (吉祥物) and affordable prices, it has quickly attracted many local customers and tourists. To suit American tastes, Mixue has created super-sweet drinks. Though much sweeter than its products in China, these drinks have become a hit, leading to a “sweetness challenge” trend. Moreover, it keeps its low-price strategy here. Items like ice cream and lemonade are much cheaper than similar products from local brands. Mixue has already achieved great success in other overseas markets like Vietnam and Thailand. Its entry into the Hollywood Walk of Fame is a key step in its global expansion. It brings the idea of “affordable and quality” products to the world’s entertainment center, challenging the traditional view of tea brands in the international market. This journey of Mixue is not just about a brand’s growth, but also a meeting between Chinese business logic and the global consumer market. It shows how Chinese brands can make their way in the world with their unique models. ( )16.What does the underlined phrase “made its mark” mean? A. became famous there B. opened its new shop there C. gave money to local people D. made special snacks for stars ( )17.What can we infer about Mixue’s drinks in the US? A.

To show Mixue’s progress in globalization and its influence on the international market. ( )20.What is the main idea of the whole passage? A. American people’s love for sweet food and drinks. B. Mixue’s global development and its special success. C. The history of a popular Chinese tea brand-Mixue. D. The introduction of the Hollywood Walk of Fame. C If you haven’t heard of OpenClaw yet, you will. In March 2026, this AI assistant became the fastest-growing open-source project ever, reaching more than 250,000 GitHub stars. What makes OpenClaw special is simple: It can really do things. Most AI assistants are conversational — they answer your questions anytime and anywhere but take no further action. OpenClaw does the opposite(相反的), working with other software like a digital helper. It runs on your own computer and can read your files, emails, and apps. You can message it through WhatsApp, and it works 24/7. Unlike ChatGPT, OpenClaw is completely yours — its code (代码) is open for anyone to see and change. For developers, this was a big step forward. Just as a lobster uses its claws to grab and handle (处理) things, OpenClaw uses its “claws” to reach into your digital world and get things done. ________ People also connect its look and ability with the animal. No place loved OpenClaw more than China. Tencent and Alibaba quickly made it available(可实现的) with one-click setup. People waited in line at Tencent’s Shenzhen office for free installation(安装) help. The Shenzhen government also offered up to 2 million yuan for projects using OpenClaw. However, being so powerful also created risks. In February 2026, researchers found more than 40,000 OpenClaw copies open on the internet. Over 60% had security weaknesses. Attackers could steal private keys and run commands(命令) on your computer — without you even knowing. OpenClaw’s rise signals a change: The future is about smart helpers that act for you. The lobster may be taking over the world. The question is: Are we ready? ( )21.What makes OpenClaw different from most other AI assistants? A. It can answer questions online. B. It can work with other software to do real tasks. C. It has fewer risks than other AI assistants. D. It was created by Chinese big companies. ( )22.Which sentence is the best to fill in the blank ________ in Paragraph 3? A. That is why people call it “the lobster.” B. It can help you with many difficult problems. C. It is one of the most popular AI tools in China. D. Some people are worried about its safety. ( )23.What does the underlined word “attackers” in Paragraph 5 probably mean? A. people who help keep things safe B. people who manage to develop new software C. people who try to harm or break into systems D. people who are prepared to provide technical support ( )24.Which saying best describes the current situation of OpenClaw? A. Better late than never. B. Every cloud has a silver lining. C. All roads lead to Rome. D. Every coin has two sides. ( )25.What is the best title for the passage? A. OpenClaw: A Powerful but Risky AI Helper B. How to Use OpenClaw for Free C. Tencent and Alibaba’s New AI D. Reasons for GitHub Stars’ Growing D ①For weeks, large wildfires spread through Los Angeles (洛杉矶). They burned down a large number of homes and many people lost their lives. As pictures of the fires spread across the internet, people noticed trees standing next to burned-out homes and cars. Some didn’t believe a fire would leave trees safe. “Is there a secret attack (袭击) on L.A. homes?” they asked. The answer is no. As many pictures show, trees can and do catch fire. ②But it’s true that some didn’t burn. Scientists say there is a simple explanation (解释) for that. ③It’s all about moisture. “It’s quite easy to understand,” said Miranda Hart, a biology teacher. “Trees are filled with plenty of water. Clearly, trees do burn when fires are big and hot enough. But if a tree full of water is next to something very dry, the dry thing will burn first and even change the way of the fire. In that way, you can imagine the fire just going around the tree.” ④Besides, the tree type also matters. Certain trees catch fire more easily. Deciduous (落叶的) trees (trees losing their leaves every year), for example, are hard to burn. That’s because their leaves include more water. While for conifer trees (针叶树), things are different. ⑤In Los Angeles, palms (棕榈树) are everywhere. They are a symbol of the city. But palm trees, with their thin and hard leaves, are especially easy to spread fire because of their structure and type. So the government advised against planting more palms. Without proper care, these trees can burn and spread rapidly during wildfires and put the people nearby in danger. ( )26. Some people questioned the wildfires in Los Angeles because ________. A. They lasted much longer than usual. B. Unknown enemies attacked homes and cars. C. Some trees didn’t burn in the fires. D. Pictures of the fires spread across the internet. ( )27. What does the underlined word “moisture” in Paragraph 3 mean? A. Environment. B. Wetness. C. Temperature. D. Height. ( )28. How would a fire pass through a tree full of water and dry things according to Hart? ◯a tree full of water □a dry thing fire’s path (路径) A. B. C. D. ( )29.Which type of tree is easier to catch fire according to the text? A. Trees with thin and hard leaves. B. Trees which drop their leaves every year. C. Trees with plenty of water in their leaves. D. Trees that are taller than the others around. ( )30. Which of the following shows the best structure of this text? (①=Paragraph 1) A. ①②//③④//⑤ B. ①//②③④//⑤ C. ①//②③//④⑤ D. ①②//③//④⑤ E You arrive at the mall anxious (渴望的) to buy the coolest computer game. Nothing will stop you, not even the price. ____31____ But wait! Is using a credit card really that simple? Using a credit card is a way of borrowing money to buy things. Credit card companies lend you money, and you need to pay it back. ____32____ In fact, they make billions of dollars this way. You spend $45 buying a pair of shoes on a credit card. Then about a month later, the credit card company sends you a bill for $45. ____33____ But what if you can’t pay the whole bill? Let’s say you pay $10 the first month. Now the credit card company begins to get money from you. They ask for extra (额外的) money, called interest (利息). Even if you don’t buy anything more, by the time you get your bill the following month, you will have more than $35 to pay back. But the good news is that a credit card is convenient. ____34____ For example, if something you bought online with your card stops working in a short time, the company may give your money back. ____35____ They spend more money than they can afford to pay back. Knowing how to use credit cards wisely will be necessary and help you to be a smart shopper. A. Mom or Dad will use a credit card to pay. B. They don’t lend you money just to be nice, however. C. Some people get themselves in trouble with credit cards. D. Besides, the credit card companies also offer extra services. E. If you pay the whole $45 back right away, it won’t cost you anything. 三、短文填词 The Terracotta Warriors are one of the greatest wonders in the world.
