“我认为我永远不会看到,一首诗可爱的树。”American poet Joyce Kilmer was right on the money way back in 1913 when he wrote his seminal work, "Trees." In autumn, the leaves of deciduous trees change from green to vibrant reds, yellows and oranges. Weekend drives to view the beautiful foliage is a must for people on the East Coast of the United States. In the winter, those leaves turn brown and brittle and eventually fall to the ground to be raked up and bagged or mulched and recycled into the earth. By spring, those trees come back to life, the green leaves appear once again and flowering trees blossom into beautiful showpieces. This is the cycle of a healthy, living tree. Besides adding so much beauty to the surrounding environment, trees also provide oxygen, shade and homes for昆虫,鸟和动物。
