问题    Elephant, a very large animal with a long flexible nose to pick up things, live in layered societies. The basic family unit is formed of small groups of adult females, who are related to each other, and their young of both sexes. The females remain in their families for life. They’re highly social, but male elephants leave their families at about 14 years of age. They travel alone or gather round in small, loose groups with other males, occasionally joining a family on a temporary basis. When males are ready to mate, they wander widely, searching for receptive females.
   The family unit, on the other hand, often contains three generations, and it can remain stable for decades, or even centuries. Then each family associates with between one and five other families, probably consisting of their more distant relatives. Scientists call these groups of families"bond groups" , and bond groups belong, in turn, to even larger groups, called clans.
   So elephants have a complex social structure. And like other social animals they have to be able to communicate.  [br] The word "bond" in Paragraph 2 can be replaced by______.

选项 A、bund
B、combined
C、consisted
D、related

答案 B

解析 词义推测题。根据文中对bond的描述Then each family associates with between one and five other families,probably consisting of their more distant relatives,可知这是两个家族的联结。A项意为堤岸、码头,B项意为联结的,C项意为组成,D项意为有联系的,故选B项。
