托福口语万能例子--环保 

There’s no trees, no grass in my community. It\'s very bare. So I have decided to give several hours each month to plant trees and grass in my community. After several years, there will be a lot of trees and grass in my community. It\'s very charming environment. You can imagine how comfortable it can be, just relax yourself on the grass, when sun is setting down and birds in the trees are singing. Second, Air pollution and noisy pollution are serious in my community. Planting trees and grass can reduce pollution.
