off the lights when leaving a room. It39。s really easy to do. Also, we39。re supposed to turn off the shower while washing our hair. And are you still using paper napkins? You39。d better stop now because paper is made from wood. If everyone uses paper napkins, a lot of trees will have to be cut down every day. Maybe it is hard to stop using paper napkins, but we must try. At the same time, we should think of good ways to recycle paper. Another thing is that we must try to take our own bags when shopping instead of using plastic bags that are provided by the supermarkets. Finally, we must stop driving cars because cars pollute the air. Instead, we39。d better ride bicycles. For one thing, it39。s good for our health. For another, it39。s much cleaner. I really hope that more and more people will realize the problem and do what they can to help make our world a better place to live in. According to Tom39。s article, fill in the blanks.
