　　主題范文：         What can we do to protect our environment,？

　　Nowadays, people all over the world begin to pay attention to our environment, because it seems to get worse day by day. I think we all have the responsibility to protect our earth. Firstly, we should save our natural resources as much as possible.Secondly, we should use the public transportation more often, instead of driving private cars all the time. Finally, we can plant more trees to help reduce the air pollution.

　　In a word, I believe the environment is very important to everyone, so we should do every thing possible to protect it.
