     Our government is aiming to build a "harmonious society" (和谐社会). In fact, I think it is everyone's duty.  

     As high school students, what should we do?

     First of all, we should love our motherland. Let's take a great interest in the development of our hometowns

and take an active part in our school activities.

     Secondly, let's fill the world with love. We should show our respect (尊重) to old people, our parents and

our teachers. We should also care for each other and help those in need. More importantly, all of us must be

honest in our daily life. Finally, let's work together to save energy and protect our natural environment,

including animals, trees, flowers and grass.

     As for myself, I will study even harder and try my best to do all the above.

     Dear students, let's start doing something good for the "harmonious society" every day, every hour, and

every minute!
