Since they re lease oxygen, trees the rivers, causing floods of droughts. Since they re lease oxygen, trees help purify our air. The greenness of trees adds to the beauty of the surroundings we live in.
To protect trees, we deem it necessary for the government to en act strict laws to prevent illegal felling of these precious natural re sources. Besides, new trees should be continuously planted in place of those which have died. If everyone loved trees, our world would be far more beautiful than it is now.
  树与人类生活幸褔息息相关。首先，它们有维护环境的功能。若是没有树木，士坏会流入河中，造成洪水或旱灾。由于树会排出氧气，有助于净化空气。而树的绿意则增添居往环境的美丽。
     为了保护树木，我们认为政府必须制订严法以防止这些宝贵的自然资源遭到盗伐。此外，我们应当不断种植新树来取代行将枯死的老树。如果大家都能爱护树木，我们的环境会比现在更美好。
(2)No one can live without trees around him. Trees can not only protect soil and water from being lost because of heavy rain and storms, but also beautify our lovely earth. When we enjoy wandering in the forest or watching the mountain covered with green trees, we feel a heart content as well as to the eyes.
Seeing that trees are so important in human lives, we can't destroy them in order to get more land to build factories or dams; instead, the government should institute laws to protect them. Besides, all of us ought to love these green scenes by true feeling, and then out country and world will be a beautiful green paradise in the future.
