What is clear,however,is that howling is often used among packmates to locate each other.Hunting grounds are distant and it happens that wolves may separate from one another at times.When this happens,howling appears to be an excellent means of gathering.
Howling,interestingly,is a contagious behaviour.When one wolf starts to howl,very likely others will follow.This is often seen to occur in the morning,as if wolves were doing some sort of “roll call”where wolves all howl together to report their presence.
动物的嚎叫有其目的性,而人的对唱也是为了呼唤同伴,所以人们认为两者在这一方面是相同的;但专家似乎发现,狼的嚎叫不仅仅是为了呼朋引伴,因为有时也会争斗,因此,研究之后,专家发现:狼的嚎叫可能是个传染形式的行为,有时也是为了呼唤同伴。
5.What is the possible similarity between wolves' howling together and humans' singing in chorus?
A.The act of calling each other. B.The sense of accomplishment.
C.The act of hunting for something.D.The sense of belonging to a group.
答案:D。细节判断题。从第二段的信息词“bond better together”以及“help the pack stay together”等可以确定两者的共同点与选项D的说法是一致的。
6.Why does Harrington think the“social bond”theory may be wrong?
