Our government is aiming to build an “economized society”. I think it is every citizen's duty to work hard to achieve this goal.
One possible version:
Our government is aiming to build an “economized society” . I think it is every citizen’s duty to work hard to achieve the goal. As students, we still can do something to help.
First, don’t waste things. We’d better go to school on food or ride a bike instead of taking a car or a bus. Turn off the lights as soon as we leave the classroom. Remember to turn off the tap at once after washing our hands. When we go out to eat in an restaurant, ask for smaller dishes and take leftover home. Before we buy something new, think whether it is necessary.
Next, use things as long as possible. When we buy things, make sure they last a long time. Don’t use a paper cup or a paper bag. It’s better to use a china cup or a lunch box. Because you can use them again.
Finally, collect what can be recycled in your classroom or in your neighbourhood and sell them. You should also buy things from recycled material.
In a word, I think , one thing we should keep in mind no matter what a small effort we can make, it do make a difference.
