Every Monday, students put one crazy idea into a red box. On Friday, the science teacher picks three ideas and the whole class discusses: “Can this work? Why or why not?” Last month, a Grade 9 girl wrote: “What if shoes could charge a phone while you walk?” Many laughed. But the teacher didn’t throw it away. She asked the physics group to test it. They found that a small generator in the heel could make a little electricity. Not enough for a laptop, but enough to power a small light. Another idea came from a boy who hated waking up: “Make a pillow that smells like fresh bread at 6:50 a.m.” The home-economics group tried it with safe food flavour. It worked—his little sister woke up happy, not angry. The school newspaper wrote: “Ideas are not just for geniuses. An idea is a seed. Some seeds are too small, some are funny, but every invention in history started as a ‘what if’.” Now the box is full every week. Students learn that an idea without testing is only a dream; an idea with testing, drawing and teamwork can become a real thing. 1. What do students do in the “Idea Box” programme? A. Throw away all funny ideas. B. Put one idea in the box and discuss some of them later. C. Only write maths problems. D. Charge phones in the classroom. 2. Why did the science teacher keep the “walking shoes” idea? A. Because it was expensive. B. Because she wanted to laugh at it. C. Because it could be tested and might work a little. D. Because a genius student gave it. 3. What did the pillow idea show? A. Bread is better than alarm clocks for everyone. B. Smell can be used in a creative, harmless way. C. Pillows should never be used at school. D. Girls are better at physics than boys. 4. What does the writer mean by “An idea is a seed”? A. Ideas grow slowly and may become something real. B. Seeds are more useful than books. C. Only farmers have good ideas. D. Inventions never start from questions. 5. What is the main idea of the passage? A. Only geniuses can invent things. B.

One rainy day, the school gate was crowded and an old man’s umbrella kept hitting people. Liu Yang noticed he had to sit on a stool to open it because one arm was weak. That night, she drew a picture: an umbrella with a button. Press once—it opens slowly. Press twice—a small light turns on. Press three times—the handle heats a little, so cold hands feel better. She called it “Warm-Shade Umbrella”. Her technology teacher said the idea was simple but kind. With two classmates, Liu Yang made a model. The heating part used a tiny safe battery. The light was from an old toy. The “slow open” used a soft spring from a broken door. They showed it at the school fair. An old visitor said, “I can’t hold a normal umbrella in winter. Yours feels like someone cares.” Liu Yang didn’t make millions of yuan. She made something more important: she saw that an idea is powerful only when it solves a real human problem. Now she keeps a notebook titled “Power of Small Ideas”. On the first page she wrote: “Don’t ask if an idea is big. Ask if it helps someone.” 1.
