Li Ming, Wang Mei and Li Lin took a walk along the river. They saw a lot of garbage. They got three plastic bags and began to pick up the rubbish. In the end, Li Ming collected the most and Wang Mei the least. But Wang Mei was very happy because she found a toy truck. It was only a little bit broken. They fixed it so it could run again. “It's not right to waste things. A lot of them can be reused,” Li Ming said.
