    Our school’s science festival just ended a few days ago. What interested me most was the time we spent making a car. It was made out of corrugated cardboard (瓦楞纸板), but could still hold a person, as well as move.

We were excited about this idea, but we found it hard to make the car. It seemed impossible for a cardboard car to carry someone. Our physics teacher showed us a video. There was some corrugated board shaped like “A” or “W” in the video, it could hold more weight. This gave us the idea to make the car after getting the proper materials (材料).

Because there was not much time left for us, we had to finish it as quickly as possible, We talked about how the car should be made and how to test it. I was glad that we were able to work closely with each other. Everyone saw the work as an interesting way to relax. When the car was finally finished, we J all wore a smile on our faces and found that all our work had been worth it, even after spending whole afternoons Working on it.

We joined the competition after we finished the car. Though we didn’t win any prizes, we found I something more meaningful than success, we learned new things about physics and learned how to get along with each other.

A. thick stone B. special glass

C. strong wood D. corrugated cardboard
