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、prevention
B、obstacle
C、stop
D、way
答案 B
解析 此题为词语辨析类题目。最后几道题需综合起来考虑，把最后几句话读懂后，考生不难发现，最后这段话和前面一段是对比的关系。前面说的是动物使用最少的武力，这段话说的是对于那些擅长从冲突中逃跑的动物，特别是对鸟来说，它们一打架，在空旷的地区，就要一方跑掉，在不自由的空间，就一定要斗个你死我活。只要理解到这点，后几道题就不难答对。本道题原文的意思是：对于那些擅长从冲突中逃跑的动物，特别是鸟类来说，并没有杀害对方的限制。A) prevention 的意思是“预防；阻止；妨碍”，但这个词通常和of 一起连用，而很少和 against连用，而且前面加动词have 的情况也没有；B) obstacle 的意思是“障碍(物)，妨碍，阻碍，干扰”，have an obstacle against sth．是固定词组，意思是“对……起阻碍作用”；C) stop 和D) way 都与原文有一定差距。
