问题     The study of animals in parks and in the wild has given a deeper knowledge of their habits: the result has been a great【C1】______in the way they are treated, housed and bred. For example, most animals are now kept in【C2】______because it has been discovered that, like people, they are happier in the company of their fellows. It has been recognized also that as they are complicated creatures, keeping them happy enough to【C3】______and multiply in captivity(囚禁)is a complicated operation. Zoo directors, keepers, and veterinarians(兽医)have【C4】______stories to tell about the problems that have to be【C5】______before romance(浪漫故事)can bloom in the zoo. Some animals will not breed without a special diet; others must feel far from human separation, and others need large spaces for their courtship dances. Some males insist on【C6】______to win their mate. Then there is the question of personal【C7】______, as was demonstrated by the female panda of the London Zoo, and the male panda in Moscow. After long and difficult discussions between representatives of the two countries involved, it was【C8】______decided that the two bears would take turns flying to each other’s residence in England and in Russia. The humans went to considerable expenses and【C9】______to bring the bears together, but they could not get them interested in each other. It seems that all pandas are hard to please; the Washington Zoo has been【C10】______with its own pair for years, without much result.
A)countless I)recognized
B)struggling J)easy
C)fighting K)flourish
D)solved L)improvement
E)eventually M)unwillingly
F)scarce N)preferences
G)trouble O)succeed
H)groups
【C10】
选项
答案B
解析 此处应填动词的现在分词或形容词。本句前面部分的all pandas暗示，句子与前面讲的英国和苏联的那对熊猫的例子存在递进关系，由此可知华盛顿动物园的人们在两只熊猫身上也肯定“费了不少劲”，却也没有多少结果。选项中符合要求的是B)struggling。
