Next autumn, when you see geese heading south for the winter, flying along in 'V' formation, you might consider what science has discovered as to why they fly that way. 41 each bird flaps its wings, it creates uplift for the bird 42 following. By flying in 'V' formation, the whole flock(群) 43 at least 71 percent greater flying range than if each bird flew44 .
When a goose falls out of formation, it suddenly feels the drag and 45 of trying to goal one--and quickly gets back into formation to take 46 of the powerful lifting of the bird in front. When the head goose gets 47 , it goes back in the wing and another goose flies tothe point. Geese honk(雁叫) from behind to 48 those up front to keep up their49 .
Finally--and this is important--when a goose gets sick or is wounded by gunshot, and falls out
of 50 , two other geese fall out with that goose and 51 it down to 52 help and protection. They stay with the fallen goose 53 it is able to fly or it dies, and 54do they launch out on their own, or 55 another formation to catch up with their own. People who share 56 direction and sense of community can get 57 they are going more quickly and easily, because they are traveling on the pushing force of one another. If we have as much sense as a goose, we will stay in formation with those people who are 58in the same 59 as we are. If we have the sense of a goose, we will 60 each other like that.
