鸟类是我们人类的朋友，它给我们的生活增添了无穷乐趣。
Birds are our human friends. They add a lot of fun to our life.
地球上没有鸟类，人类将会遭到灾害，一些有害的昆虫，小兽就会繁殖许多后代，把郁郁葱葱的树木和碧绿碧绿的草原一食而空。地球上的动物及我们人类就会失去食物。
There are no birds on the earth, and human beings will suffer disasters. Some harmful insects and small animals will breed many offspring and eat the lush trees and the green grassland. The animals on earth and us will lose our food.
猫头鹰是“捕鼠能手”它有一双铜铃似的眼睛，能在夜间看到极小的东西，还有一对能听到细小声音的耳朵。它一个夏季可捕到1000只田鼠。
The owl is a "rat catcher". It has a pair of eyes like a copper bell. It can see very small things at night. It also has a pair of ears that can hear small sounds. It can catch 1000 voles in a summer.
啄木鸟是“森林大夫”，有像听诊器一样的钢嘴，通过敲打树木听声音，就能准确判断捕捉到害虫。像这样的益鸟，还有许多。
The woodpecker is a "forest doctor", with a steel mouth like a stethoscope. By tapping the trees to listen to the sound, you can accurately judge and catch pests. There are many good birds like this.
所以，我们每个人都要有责任，爱护鸟类，爱护我们的朋友。
Therefore, each of us should be responsible for taking good care of birds and our friends.
