4.Howling is a behavior commonly observed among a wolf pack.As pack animals,wolves work together to hunt and rely on howling as an important means of communication among each other.There are different explanations of a wolf's howl and it appears that there may be more to discover.One theory is that wolves howl to bond better together.It's almost as if howling together helps the pack stay together.Perhaps it's something similar to people feeling a sense of involvement with each other when singing a song together.But this theory may be wrong,explains Fred H.Harrington,a professor who studies wolf behavior.
Indeed,there have been times when wolves have been seen one moment howling in a chorus,and the next,quarreling among each other.It appears that usually the lowest-ranking members of the pack may actually be"punished"for joining in the chorus at times.So is howling a way to strengthen a social bond or just a way to reconfirm (重新确认) status among its members?-Why do wolves howl for sure?
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 behavior.When one wolf starts to howl,very likely others will follow.This is often seen to happen in the morning,as if wolves were doing some sort of"roll call"where wolves all howl together to report their presence.

A.The act of calling each other.

分析 本文是一篇说明文,主要讲述了有关狼咆哮的现象,咆哮是被观察到的狼群间的一种普遍行为,和其它动物一样,狼是群居动物,一起猎食,咆哮是狼群间相互交流的一种方式,关系狼的咆哮有好几种解释,似乎有很多的发现.一种理论是狼是如何更好地聚集在一起.他们似乎像是被打包在一起,也有点类似人类在一起感觉到一种互相牵连的感觉,但这种观点好像是错的.有一些时候狼会在一起合唱,然后接下来彼此争吵.狼为什么要咆哮,是一种加强社会联系和确认成员间的地位,咆哮常常是在群体里找到彼此,狼的咆哮是有传染性的
解答 28-31 DCBD
28 D 细节理解题.根据文章第二段的"One theory is that wolves howl to bend better together.It's almost as if howling together helps the pack stay together.Perhaps something similar to people feeling a sense of involvement with each other when singing a song together"可知,一种理论是狼是如何更好地聚集在一起,他们似乎像是被打包在一起,也有点类似人类在一起感觉到一种互相牵连的感觉,咆哮常常是在群体里找到彼此,即归属感故选D.
29 C 细节理解题.定位关键词"wrong",根据文章第一段中"there have been tines when wolves have been seen one moment howling in a exhorts,and the next,quarreling anions each other."可知,这种观点好像是错的,因为有一些时候狼会在一起合唱,但然后接下来狼群间会彼此争吵,再由"It appears that usually the lowest-tanking menthes of the pack may actually be"punished"for",可知,排名低的狼似乎还会受到惩罚,故选C.
30 B 细节理解题.定位"sure"和文章第四段的"what is clear"相对应,再由"is that howling is often used among packmates to locate each other"可知,狼的嚎叫是狼在召唤同伴,故选B.
31 D 猜测词义题.定位"contagious behavior",从该词下文举的例子"When one wolf starts to howl,very likely others will follow."说明"contagious behavior"的意思的解释,可以看出Howling…is a contagious behavior意思很可能是"howling spreads from one to another"的意思,即是一种传染行为,故选D.
