Question

Science has discovered that as each bird flaps （拍打） its wings，it makes uplift for the bird behind it．By flying in a"V"formation，the whole group adds at least 71percent greater flying range （范围） than if each bird flew on its own．In autumn，geese head south for the winter，flying in a"V"formation （队形）．
People who share a common direction and sense of community can get where they are going more quickly and easily，because they are traveling with the help of one another．
When a goose falls out of formation，it won't try to go it alone but will quickly get back into formation．
If we have the sense of a goose，we can stay in formation with people who are heading in the same direction as we are．
When the head goose gets tired，it goes back in the wing and another goose flies to the point．
It is sensible to take turns to lead，whether with people or with geese flying south．
Finally，when a goose gets sick or is wounded （受伤） by a gunshot，two other geese fall down with that goose．They follow it down for protection and to lend help．They stay with the fallen goose until it is able to fly or until it dies．
If we have the sense of a goose，we can stand by each other like that．
