1, pine tree is like a emerald triangle tree, like a big umbrella. From a close distance, the leaves of pine tree are like a sharp needle. The older "needle" is dark green, while the younger one is tender green.

2. There is a big pine tree in the west of my hometown village. The trunk of the pine tree is not high. Maybe one person comes high, and when one person comes high, it forks. Each main fork is also very thick, and it stretches very long and far, and almost all of them are parallel, so it forms a big crown, but the whole crown is not particularly high from the ground. Just like the goddess scattered flowers, the whole crown forms a big shade.

3. Pine trees have a straight brown trunk, a green crown and prickly pine leaves, which look strong and straight. Although it has no delicate colors, it is simple and beautiful, slim and graceful, and can withstand the wind and snow.

4. The tall and straight branches of pine trees are dark brown and grow straight up, as if they were higher than the sky. I stretch out my hand to touch it, and its rough trunk looks like a cracked land and an old man's hand. The branches of pine trees spread out in all directions layer by layer, as if in a competition, forming a big green umbrella.

5. Pine trees are a kind of evergreen trees. Most of them are tall trees, and a few pine trees are shrub-like. When I was young, the crown of the tree was pyramid-shaped, and the branches were mostly round and round. After the seedlings are unearthed and cotyledons are unfolded, the first ones are primary leaves, which are solitary, spirally arranged in rows, linear and lanceolate, and the leaf margin is toothed.
