a tree has three main parts, the roots, the branches and the leaves. under the ground, the roots spread out so that the tree can stand firm. above the ground, the roots form the trunk, and the trunk supports the branches.
near the top of the tree, the trunk divides into branches. at the top of the tree, the leaves grow out of the branches. the leaves receive sunlight to help the whole tree grow.
today is tree-planting day. we went to plant trees in daning greenland. as soon as we arrived, we began to work.some were digging holes, some were planting and others were watering.
we all know trees are very useful to man. growing trees means saving man himself. we all worked very hard. when the sun went down, we came back home. although we were very tired, we felt very happy.
