[2025 江苏南通中考]In 1876, Alexander Graham Bell made a great invention—the telephone. For the first time in history, people could talk to someone far away just like they were in the same room. But today, phones can do much more than just make calls!
The story of mobile phones began with two-way radios. These early devices（设备）had a big problem—they only worked when people were close to each other. In the 1940s, smart scientists found a way. They built tall radio towers across the country to pass signals（信号）easily.
Everything changed in 1973 when Dr. Martin Cooper made the first real mobile phone call. During the 1980s, mobile phones became smaller but were still very expensive. Only rich business people could afford them, and the phones looked like big plastic bricks.
The 1990s brought another big change. Phones became cheaper and smaller, fitting easily in pockets. Soon, almost everyone had one. Text-messaging became popular. People started writing short messages instead of making phone calls. Meeting time became more flexible（灵活的）because you could just text the person “I’ll be 15 minutes late.”
Now we have smartphones—like powerful minicomputers in our pockets. We use them to take photos, watch videos, play games, and even help with housework! Messaging apps let us send videos and long messages easily. While phones help us stay connected, some people worry we spend too much time on them.
When looking back, it’s amazing how phones have changed. From Bell’s simple telephone to today’s smartphones, this has truly changed our lives. What will phones be able to do next? Only time will tell!
20. When did Alexander Graham Bell invent the telephone?
21. Why did scientists build tall radio towers in the 1940s?
22. Who made the first real mobile phone call?
23. How can smartphones help us in our life?（请给出两个例子）
24. 新考向开放性试题 What do you think the future phones might be like?（请自拟一句话作答）
