今天放学后，妈妈到处找不到我。你们知道我去做什么了吗？我呀，去捡“垃圾”了——塑料瓶。这样可以保护环境，还可以卖，换成钱呢。我想把钱存起来，捐给四川灾区的小朋友们。
Today, after school, my mother couldn't find me anywhere. Do you know what I did? I went to pick up "garbage" - plastic bottles. In this way, we can protect the environment, sell it and exchange it for money. I want to save the money and donate it to the children in Sichuan disaster area.
