Next fall when you see geese heading south for the winter or flying in “ V” formation(队形),you might consider what science has discovered as to why they fly that way.
As each bird spreads its wings,it creates an uplift (上升力)for the bird immediately following. By flying in " V" formation the whole flock(鸟群)adds at least 71% greater, flying range,than if each bird flies on its own. people who share a common direction and sense of community can gel where they are going more quickly and easily because they are (raveling on the thrust (推动力)of her .
When a goose falls out of the formation, it suddenly feels the drag and resistance of trying lo go it alone and quickly gels back into formation to take advantage of the lifting power of the bird in front. If we have as much sense as a goose, we will stay in formation with those who are headed the same way we are. When the head goose gets tired, it flies backwards and another goose flies point. It is sensible to take turns doing demanding jobs, whether St is with people or with geese flying south.
Geese honk (雁叫) from behind lo encourage those up front to keep up their speed. What do we say when we honk from behind?
Finally and this is important,when a goose gets sick or is wounded by gunshots, and falls out of formation , two other geese fall out with that goose and follow it down to lend help and protection . They slay with the fallen goose until it is able to fly or until it dies, and only then do they launch out on their own,or with another formation to catch up with their group. If we have the sense of a goose,we will stand by each other like that.
first three paragraphs chiefly deal with .
A. scientific discovery about geese.
B. the importance of (light formation.
C. the advantages of nn formation.
D. the reasons for geese % flight.
26. The phrase which can best replace “stand by” in the last sentence is “ ”.
against. B. support. C. sit by. D. obey.
27. What does the author want to learn from the geese ?
work. B. Sympathy. ness. lligence.
