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
【C9】
选项
答案
M
解析
空格位于no和介词of之间,应为名词,且被official修饰。本句解释难以确切知道有多少克隆动物的原因,此处指出其中一个原因“没有关于克隆的官方……”,registry符合句意。
