A day at the Eco-Technology Fair
Hi, I'm Xiaopu. Last Saturday, our school held an Eco-Technology Fair. Many students and parents attended (参加) it.
First, we listened to a talk about "3R" (reduce, reuse, recycle). The teacher said, "We can reduce plastic waste by using cloth bags." Then we saw a show about great scientists. A student introduced Yuan Longping — he developed hybrid rice to help solve hunger problem. We also saw models of inventions, like the light bulb and the wheel. They made our life easier!
In the plant area, we learned about water lilies. Their big leaves can float on water and keep dry. The guide told us, "Plants need sunlight to make food." At last, we made crafts with recycled materials. I used an old plastic bottle to make a small flower pot.
It was a wonderful day. I learned that science and environmental protection can make the world better.
Task 1: Read and write（学校举办了生态科技展。读一读，根据Xiaopu介绍的内容填空）
