This summer, Dad took Xiaoyu to the Future Tech Expo(未来科技博览会）for middle school students. Upon entering, Xiaoyu noticed a student interactive（互动的）brochure（手册）with a welcome message and asked his dad to help fill in the blanks.
Hello, everyone! Welcome to the Future Tech Expo. Today, I want to talk about how AI is making our lives better in China.
At home, AI makes daily tasks easier. Smart speakers can play music or control lights with 1 . Sensors(传感器）in fridges（冰箱）can tell you when you need to buy more food. These 2 make homes safer and more convenient.
In schools, AI is a great helper. It can 3 students' homework for grammar mistakes and suggest reading materials based on their interests. Some classrooms even use AI cameras to 4 if students are paying attention.
AI also helps protect the environment. In farms, drones（无人机）with AI cameras check the health of crops and 5 water usage. This makes farming more efficient（高效的）and saves 6 resources（资源）. In cities, AI systems analyze（分析）air quality and help reduce pollution.
The examples show that AI, no matter how 7 , can make a big difference. Whether it's a small smart device or a large environmental system, AI is here to build a 8 future for all.

After reading the brochure, Xiaoyu invited dad to visit the three recommended zones he was interested in together.

Zone 1:Smart Agriculture(智能农业）
AI helps farmers grow crops better. Drones fly over fields to take pictures of plants. AI then analyzes these pictures to find diseases(病害）or water shortages（缺水）early. This allows farmers to solve problems quickly and use fewer chemicals（化学药品）, making food safer.
Zone 4:Healthcare(医疗健康）
In hospitals, AI-powered robots assist doctors in surgeries（手术）. These robots can work with great precision（精准度）, even in tiny parts of the body. AI also helpanalyze X-rays and MRI scans（核磁共振扫描）to detect（检测）illnesses like cancer at an early stage, saving many lives.
Zone 5:Smart Cities(智慧城市）
Traffic lights in some Chinese cities are now “smart”. AI systems adjust their timing based on real-time traffic data（实时交通数据）, reducing jams（拥堵）by up to 30%. Waste bins with sensors can tell when they're full and send signals（信号）to garbage trucks, making city cleaning more efficient.
After visiting the three zones, Xiaoyu still has some questions about the exhibition content. Please answer these questions for him.
（）9. What can AI do in farming?
A. Make drones fly faster. B. Detect plant diseases early.
C. Grow crops without water. D. Create more chemicals.
（）10. How does AI help in healthcare?
A. It performs surgeries instead of doctors.
B. It makes X-rays more comfortable.
C. It detects illnesses at an early stage.
D. It produces more medicine.
（）11. What is the feature(特点）of smart city traffic lights?
A. They never turn red. B. They adjust timing with AI.
C. They work only in the day. D. They cause more traffic jams.
（）12. Which of the following is TRUE?
A. AI drones are only used in big cities. B. Smart waste bins can clean themselves.
C. AI makes farming and city life better. D. AI in healthcare is still a concept(构想）.
（）13. What's the main idea of the passage?
A. The history of AI. B. How to use AI at home.
C. Different uses of AI in China. D. The future of AI in schools.
In Zone 5, the guide Lulu noticed Xiaoyu was curious about the expo and started chatting with him. Complete their dialogue using the given Chinese words.
Lulu: Hi there! I'm Lulu, your expo guide. Have you ever been to a technology expo before?
Xiaoyu: Yes! Last year, I went to a science expo, but this expo is 14. （更加）exciting!
Lulu: Glad to hear that! Did you notice any special exhibits today?
Xiaoyu: Yes! The smart agriculture drones are amazing. Are they the same as those in other expos?
Lulu: Actually, these are 15. （最小的）drones used in farming right now—only 20cm wide! But they can fly 16. （更快）than most others. Have you seen any AI products at home?
Xiaoyu: Yes! We have a smart speaker. It helps my mom control the lights with her voice.
Lulu: Nice! Many families use AI for daily tasks. What's 17. （最有用的）AI tool in your life?
Xiaoyu: Probably the robot vacuum(扫地机器人）—it cleans our house more efficiently than I do!
Lulu: Haha, AI does make life easier. Thanks for talking with me!
At the exit of the expo, there is an AI knowledge competition area, and Xiaoyu wants to participate in it. Please help him determine whether the following statements are correct or not.
18. In Smart Agriculture, AI drones mainly play music for crops. （T/F）
19. In Healthcare, AI-powered robots can assist doctors in performing surgeries with high precision. （T/F）
20. In Smart Cities, waste bins with sensors can clean themselves automatically. （T/F）
21. AI in healthcare is only used for taking care of patients' daily needs. （T/F）
Finally, Xiaoyu succeeded in the challenge and won an expo badge.
22. Upon arriving home, Xiaoyu hopes to share with his good friend Mike the sights and reflections from today's expo. Please help him write a short letter to introduce the interesting experiences at the expo.

Dear Mike,
I had a really fun time at the Future Tech Expo today! Dad and I visited three cool zones. In Smart Agriculture, AI drones take pictures of plants to find diseases early. That helps farmers grow safer food.
The Healthcare zone was amazing! AI robots help doctors perform surgeries very accurately, and they can even find illnesses like cancer in X-rays faster. Who knew AI could save so many lives?
My favorite was the Smart Cities zone. The traffic lights can change timing with AI to reduce jams, and smart waste bins tell trucks when they're full. So clever!
We also collected stamps by doing challenges and I got a cool expo badge. The expo showed me AI is everywhere—at home, in schools, and even for the environment. What do you think of these uses? Have you seen any cool AI things lately? Write back soon!
Best wishes,
Xiaoyu
