问题     A major mason for conflict in the animal world is territory. The male animal【C1】______an area. The size of the area is sufficient to provide food for him, his【C2】______and their offspring. Migrating birds, for example,【C3】______up the best territory in the order of "first come, first【C4】______". The late arrivals may acquire【C5】______ territories, but【C6】______food is available, or they are too close to the【C7】______of the enemies of the species.
    When there is conflict over territory, animals will commonly use force, or a【C8】______of force, to decide which will stay and which will go. It is interesting to note,【C9】______, that animals seem to use only the【C10】______ amount of force necessary to drive away the intruder. There is usually no killing. In the【C11】______of those animals which are capable【C12】______doing each other harm, there is a【C13】______for the losing animal to show the winning animal that he wishes to submit.

选项 A、places
B、nests
C、residences
D、habitats
答案 D
解析 此题为词语辨析题。原文此处的意思是：晚来的可能占到更大的领地，但是得到的食物可能会更少，或者离敌人的领地距离较近。再观察答案，可判断出要选择的这个名词是动物栖息地的意思。A) places 是通指的“地方”意思，而并不特指动物的栖息地；B) nests 指鸟的巢，而不是动物的栖息地，尽管前文曾说是Migrating birds，但我们并不能判定其敌人也是鸟类； C) residences 的意思是“the place in which one lives；a dwelling.(某人居住的地方；住宅)”，指人居住的地方，而不是动物；D) habitats 的意思是“栖息地，某种生物或生态群体生存繁衍的地区或环境类型”，这个词专指动物的栖息地，所以为正确答案。
