我们喜欢看世界上的动物，但你知道它们会教会我们什么吗？看看加拿大的大雁，它们会让我们知道什么是团队精神，什么是合作。

Many of us enjoy watching animals in the world. But do you know they can teach us?

Geese(雁), for example, teach a very good lesson about   41  . In the fall, Canada geese fly to the warm south to   42   Canada’s cold winter. They lift off in no order. Yet   43   they form a V shape, with one bird leading the group.

This V shape allows geese to   44   energy. 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   45   has the hardest job. When it gets   46  , it moves behind, and another bird moves into the lead. By sharing the role, the group can travel great distances. Geese flying in a V shape can fly 70 percent farther without   47   than birds flying alone.

During the long flying journey, geese communicate with one another. They honk(鸣叫) to   48   the birds up front to keep up the speed. They also cheer each other up   49   working toward a common goal.

What have we learned from the lovely geese’s experience and skills?   50   together! Whether it is our personal lives or our jobs, we need other people. We need the spirit of teamwork!
