2025中考英语作文预测 必背!! 热门话题一:环保与可持续发展 My Experience of Promoting Garbage Classification Last weekend, I volunteered at my community’s garbage classification campaign. I created colorful posters showing how to sort recyclables, kitchen waste, and harmful trash. When a grandmother asked, "Why can’t plastic bags go in the blue bin?" I explained they can choke sea turtles. Her eyes widened, and she nodded seriously. Later, I saw her teaching others the rules! By evening, 30 families had signed our "Sort It Right" pledge. This made me proud—real change starts with one voice.
