A

Have you ever waited for a bus in the rain and wished the stop could tell you when the bus was coming? In Suzhou, a smart bus shelter now does exactly that. It has a solar roof, a digital screen, and a seat that warms itself when the temperature drops below 10℃.

The shelter was designed by a team of college students. They noticed that old shelters only had a sign with the route number. Passengers had no idea how long they would wait. So they added a small computer that connects to the city's bus system. The screen shows the bus position, the weather, and even local news.

What makes it special is the bench. It uses power from the sun to stay warm in winter. The roof also collects rainwater and waters plants beside the shelter. “We wanted the shelter to serve people and the environment,” said one designer.

Some people worried it would cost too much. But the team said the solar panel pays for itself in three years. Now five such shelters stand near Suzhou Industrial Park, and more will appear next year.

1. What is the main purpose of the smart bus shelter?

A. To sell bus tickets.  B. To show bus information and comfort passengers.

C. To replace bus drivers.  D. To advertise local shops.

2. Who designed the smart bus shelter?

A. Old passengers.  B. City officials.  C. College students.  D. Bus drivers.

3. How does the bench get warm in winter?

A. By using electricity from the city.  B. By burning coal inside.

C. By using power from the solar roof.  D. By people sitting on it.

4. What does the underlined word “itself” in Paragraph 4 refer to?

A. The solar panel.  B. The bus.  C. The screen.  D. The team.

5. What is the best title for the passage?

A. How to Take a Bus in Suzhou  B. A Smart Shelter: Small Idea, Big Help

C. College Life in China  D. Solar Energy in Daily Life

B

When 14-year-old Chen Yu saw her grandma forgetting to turn off the gas, she didn't just worry—she

acted. She spent six months making a “memory knob” for the stove. The knob looks normal, but it has a timer and a small voice box. If the gas stays on for more than 20 minutes, the knob says in a gentle voice, “Grandma, please check the fire.” After 30 minutes, it shuts the gas off by itself.

Chen Yu learned basic coding from her school club. She drew the plans, printed the case with a 3D printer, and tested it on her own kitchen stove. At first, it failed three times. Once it shut the gas off while her mother was cooking noodles. But she didn't give up.

Her school sent the invention to a city youth fair. A local factory liked it and helped make 100 pieces for old people's homes. The factory didn't pay Chen Yu much, but they gave her a small lab to keep creating.
