问题     If you didn’t know any better, you might think that Star, Snuppy, CC and ANDi were just a bunch of interesting names. You’d only be half right. These creative names【C1】______belong to a pig, a dog, a cat and a monkey that were among the first clones of their species.
    You’re likely already familiar with Dolly—the sheep that achieved near【C2】______status as the first mammal to be cloned successfully using adult animal cells. But Dolly is not alone. The world’s first clone—a tadpole—was actually created as early as in 1952. And at least a dozen different species have been cloned since: everything from the common cow to the【C3】______guar, a type of wild ox.
    Animal cloning has come a long way since that first tadpole more than 50 years ago. The U.S. Food and Drug Administration’s(FDA)declaration in early 2008 that food products【C4】______from the clones of cows, pigs and goats are safe for human consumption【C5】______an already growing interest in the process.
    Cloning may have【C6】______uses besides its ability to help farmers【C7】______breed quality burgers and bacon. Other potential uses【C8】______the preservation of species, biomedical research, drug and organ production and even commercial ventures.
    It seems that finding out exactly how many cloned animals have been produced is almost as difficult as producing them in the first place. There’s no official【C9】______of clones, and laboratories aren’t required to report every single tadpole or mouse they create. But armed with a bit of knowledge concerning animal cloning and its【C10】______it’s likely to narrow down the contestants to a possible field.
    A)inclusive B)derived C)applications D)actually
    E)additional F)intensified G)visualized H)celebrity
    I)include J)typically K)compromise L)endangered
    M)registry N)duplicates O)consistently
【C10】
选项
答案C
解析 空格在形容词性物主代词its后，应为名词。本句说的是找到更多克隆动物的方法，那就要具备这方面的相关知识，此处应选用applications，填入文中意为“只要掌握一点关于克隆及其应用的知识，就能缩小找寻被克隆的动物的范围”。
