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
【C4】
选项
答案
B
解析
空格位于that引导的从句中,从句的主语是food products,谓语是are safe,可见空格应该是修饰food products的后置定语。from the clones of…表明填入空格的词应表示某种动向且能与from搭配,最可能是过去分词。derived符合句意,表明“源自克隆牛、克隆猪和克隆羊的食物可以安全食用”。
