Many of us enjoy watching animals in the world. But do you know they can teach us?
Geese(大雁), for example, teach a very good lesson about1 In the fall, Canada geese fly to the warm south to 2 Canada's cold winter. They lift off in no order. Yet3 they form a V shape, with one bird leading the group.
This V shape allows geese to 4 energy(能量). When the front bird moves its wings up and down, the resulting force of the air lifts the next one. This continues down the line. The bird 5has the hardest job. When it gets 6 , it moves behind, and another bird moves into the lead. By sharing the role, the group can travel great distances (距离). Geese flying in a V shape can fly 70 percent farther without 7 than birds flying alone. During the long flying travel, geese communicate with one another. They honk(鸣叫)to 8 the birds up front to keep up the speed I (速度). They also ,cheer each other up 9working toward a common goal (目标).
What have we learned from the lovely geese's experience and skills?10 together! Whether it is our personal lives or our jobs, we need other people. We need the spirit of teamwork!
