二、阅读理解
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.
“I didn't invent it for a prize,” Chen Yu said. “I just wanted grandma to be safe.” Her story spread online, and now three middle schools have opened “family safety labs” like hers.
6. Why did Chen Yu make the “memory knob”?
A. To win a national prize. B. To stop her grandma forgetting the gas.
C. To sell it to a factory. D. To learn how to code.
7. What does the knob NOT do?
A. Speak to remind users. B. Turn off the gas automatically.
C. Cook noodles for the family. D. Count time with a timer.
8. How many times did Chen Yu fail before success?
A. Once. B. Twice. C. Three times. D. Four times.
9. What does the factory do for Chen Yu?

三、句子还原
The “idea lamp” is a new desk light for students. It turns on only when you are sitting correctly and starts dimming if you lean too close to the book. 1___
The lamp was born from a simple question: why do we always tell children “sit straight” but give them no tool to check by themselves? 2___ They put a distance sensor and a posture chip inside a normal-looking lamp.
When the user bends over, the sensor finds the head is too low. 3___ If the user sits right again, the light returns to full brightness. Parents can also connect the lamp to a phone and see how long the child studied with good posture.
Some teachers worry students may depend on the lamp and forget to build habits. 4___ They say the lamp is just a helper, not a teacher. The real power is in the idea behind it: small reminders shape long-term behavior.
In the future, the team plans to add a reading-speed counter and a rest reminder. 5___
A. The light was designed by two high-school girls.
B. Then the light sends a soft blue color instead of white.

四、任务型阅读
Imagine a student who loves painting but lost the use of his right hand after an illness. He watched others draw freely and felt left out. How could he paint again?
Now a new tool called the “eye brush” has come out. It lets people draw pictures by moving only their eyes. The brush was developed by Lin Fang, a software engineer, after she visited a rehab center. She saw a young man staring at a canvas, unable to hold a pencil. He used a wheelchair and could only move his head a little.
Lin Fang remembered how her little brother used to blink to choose TV channels. Suddenly she realized: eyes can choose colors, too. She started to work with a hospital. Eight months later, the eye brush was ready. It has a small camera that follows the pupil. The user looks at a color on the screen, blinks once to pick it, looks at the canvas, and blinks to put the dot. A full line is made by looking and blinking at the start and the end.
The hospital first tested it on 12 patients. Over 9 million people in China have hand disabilities. When the tool works well, it will bring art back to many of them.
A user named Zhao Lei says, “As a man who thought painting was gone for me, I am shocked by this. My eyes now dance on the screen. That never happened before.”
根据短文内容,回答下列问题。
1. What made Lin Fang decide to develop the eye brush?
________________________________________________________________
2. What tools must a person with hand disability have if he wants to paint with the eye brush?
________________________________________________________________
3. How does the eye brush pick a color?

4. What does Zhao Lei think of the eye brush?

A Small Idea, A Better Life
In this unit, I read about many small inventions. My favorite is the “memory knob” by Chen Yu. It reminds old people to check the gas and turns it off by itself. A small idea from daily life can keep a family safe.
It tells me that inventions do not need to be huge. If we watch carefully and think bravely, our ideas can also make life better. I want to be such a teenager.
