An unforgettable experience in my life, there are many experiences I can't forget. I still remember what happened last year. It was tree planting day.

As soon as we got to Lu Xun Park, we went to plant trees. We started to work. Some were digging holes, others were planting trees.

We all worked hard to plant more trees, because we all know that trees are the best anti pollution agent. They are very useful for human beings. When the sun goes down, we are very tired but reluctant to go home.

We feel very happy It's my first time to do something meaningful to protect the environment.
