整理的书面表达，还不错！

    Dear fellow students,
    Our government is aiming to build a 'harmonious society'. I think it is every citizen＇s duty to work hard to achieve th is goal.
    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 and activities.
    Secondly, let’s fill the world with love. We should show our respect for 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 faithful and honest in our daily life.
    Finally, let’s work together to save energy and protect our natural environment, including animals, trees, flowers and grass.
