Answer 1

One possible version:
                                                      Keep Our City Clean
    I used to see cars producing smog on the street,students leaving the water taps on after using them,people throwing things everywhere without thinking. How terrible it was! Then,what should we do?
    We should not throw rubbish onto the road. Instead we should pick up rubbish and throw it into the dustbins. After washing, we'd better turn off the water tap. Besides,we can go to school by bike or bus instead of by car. Of course we should cut the use of plastic bags.
    We are a family and we should try our best to keep our city clean.
