题目内容
9.Next autumn when you see wild geese heading south for the winter flying in a V formation,you might think about what scientists have discovered as to why they fly that way.As each bird flaps its wings,it creates uplift(提升) for the bird immediately following.By flying in a V formation the whole group 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 get where they are going more quickly and easily because they are traveling on the push of one another.
When a wild goose falls out of the formation,it suddenly feels the drag and resistance of trying to go alone and quickly tries to get back into the formation to take advantage of the lifting power of the bird in front.When the head goose gets tired,it flies back into the formation and another goose flies to the front.It is wise to take turns doing difficult jobs whether it is people or wild geese flying south.
Wild geese honk (发出雁叫声) from behind to inspire those up front to keep up their speed.What can we learn from this?
When a wild goose gets sick or wounded by gunshots,and falls out of the formation,two other geese will fall out with that goose and follow it down to lend help and protection.They will stay with the fallen goose until it is able to fly or until it dies,and only then will they go on with their own or with another formation to catch up with their group.

解答 24.B 细节辨析题.By flying in a V formation the whole group adds at least 71% greater flying range (航程) than if each bird flies on its own."以V字飞行能使整个团体比单个的行程多至少百分之71";故答案为B.
25.B 推理判断题.根据第五段Wild geese honk (发出雁叫声) from behind to inspire those up front to keep up their speed."野生大雁从后面发出叫声鼓励前面的大雁保持速度."根据句意联想到人类社会,可知答案为B.
26.C 细节理解题.根据句子:When a wild goose gets sick or wounded by gunshots,and falls out of the formation,two other geese will fall out with that goose and follow it down to lend help and protection."一旦有只野雁生病或是受了枪伤跟不上队伍,那么两只野雁将会退出队伍陪伴这只野雁,并给予帮助和保护."故答案为C.
27.A 推理判断题.根据句子When a wild goose falls out of the formation,it suddenly feels the drag and resistance of trying to go alone and quickly tries to get back into the formation to take advantage of the lifting power of the bird in front当一只大雁从编队中掉下来时,它突然感觉到了,很快地试图回到编队中,利用前面鸟的升力.可见雁可以通过拍打翅膀来帮助跟随它的人.所以答案选A.
