【正确答案】One possible version:
   
   Dear fellow students,
   Our government is aiming to build a "harmonious society" (和谐社会). I think it's every citizen's duty to work hard to achieve this goal.
   As primary school students, what should we do?
   First of all, we should love our country, our hometown and our school. Secondly, we ought to respect our family members, teachers and classmates. Thirdly, we must learn to be honest and ready to help others as well. Fourthly, we are not supposed to waste any energy, such as water, oil, coal and electricity. Finally, we should protect our environment, wild animals and plants to make the world a better place to live in.
   It's a good idea to begin with such little things as helping with the housework, giving my teachers and classmates the needed aid and picking up the rubbish whenever and wherever I see it.
   Dear fellow students, let's start right now and spare no effort to do a little bit every day, every hour, and every minute!
