再问： 问题就是我写不出啊~~~
再答： 我服你了！ 给：Hello everyone! My name is flower. Today I want to talk about trees. Trees are very important of us. If no trees, human has no fresh air to breath. There is much soil erosion , rivers dry and farmland change to desert. A lot of paper is made of wood. Every year, we consume 1000 cubic meters of timber per second for paper. We use too much paper , so how can we protect trees. As students , how can we do it ? We can practice the economical use of paper. Such as using of exercise notebooks and paper napkin , recycle waste paper . Heal the world, make it a better place for you, for me and for the entire human race. That’s all. Thank you!
