小题1:Painkillers in a tablet can make your headache go away. Antibiotic cream（抗生膏）from a tube can prevent your cuts from becoming infected. But can medicine come packaged in chicken eggs?
A team of scientists from Scotland says yes. They"ve engineered special chickens that lay eggs with disease -treating drugs inside.
小题2:Animals make thousands of proteins—they’re the main ingredient in skin, hair, milk, and meat. Since animals can make proteins easily, they’re good candidates for making protein drugs.
Researchers have already made cows, sheep, and goats that pump out protein drugs in their milk. But chickens are not expensive to take care of; what’s more, they need less room, and grow faster than these other animals. “小题3:”says Simon Lillico of the Roslin Institute near Edinburgh, Scotland.
Lillico and a team of researchers changed chickens’ DNA—the code that tells cells how to make proteins so that the birds’ cells made two protein drugs. 小题4:
The scientists altered the chickens’ DNA so that the birds made these drugs only in their egg whites (蛋清). This protects the chickens’ bodies from the drugs’ possible harmful effects and makes it easy for scientists to collect the drugs.
These special chickens can pass on their drug-laying abilities to their chicks. 小题5:The scientists need to improve these chickens before they roost (栖息) in drug companies’ labs. The birds don’t make enough drugs to treat people yet. But once the researchers perfect their technique, you might eventually take your medicine sunny-side up.

A．Medicine comes in lots of different uses.

B．Those qualities could make chickens a better choice to become living drug factories.

C．So far, the Scottish researchers have bred five generations of drug—producing birds.

D．Some chickens are found having the ability of treating diseases.

E. One drug can treat skin cancer, and the other treats a nerve disease called multiple sclerosis(硬化).
F. These drugs are made of molecules called proteins.
G. Medicine comes in lots of different packages.

答案

小题1:G
小题2:F
小题3:B
小题4:E
小题5:C

解析

试题分析：这是一篇科技类阅读。一组来自苏格兰的科学家说可以。他们研制出一种特殊的鸡。这种鸡生的蛋里面含有治病药品。这些药品都来自于那些经设计后能在其蛋白中产出某些药品的鸡。这些药品都是由叫做蛋白质的分子构成的。
小题1:根据后文Painkillers in a tablet can make your headache go away. Antibiotic cream from a tube can prevent your cuts from becoming infected. But can medicine come packaged in chicken eggs? 片剂类止痛药能消除你的头痛。装在管子中抗生素膏能预防你伤口感染。但药品能装在鸡蛋中吗？可知这里应该是：药品有不同的包装。故选G。
小题2:根据后句Animals make thousands of proteins动物能产生很多的蛋白质。可知这里应该是These drugs are made of molecules called proteins.这些药是由叫蛋白质的成分构成。故选F。
小题3:根据前文But chickens are not expensive to take care of; what’s more, they need less room, and grow faster than these other animals.但是鸡饲养成本更低，而且所需空间较小，生长较其它动物快。所以这里应该是：Those qualities could make chickens a better choice to become living drug factories鸡的这些特性使之成为转化成活性药品工厂的最佳选择。故选B。
小题4:根据前文the birds’ cells made two protein drugs这样鸡的细胞就能产生两种蛋白质药品。可知接着要说明这两种蛋白质，故用One drug can treat skin cancer, and the other treats a nerve disease called multiple sclerosis一种治疗癌症，另一种治疗叫做多样硬化的神经方面的疾病。故选E。
小题5:根据后文The scientists need to improve these chickens before they roost (栖息) in drug companies’ labs在这些鸡进入药厂的实验室之前，科学家还得对这些鸡进行改善。可知这里应该是：So far, the Scottish researchers have bred five generations of drug—producing birds.到现在为止，苏格兰科学家已经五种生产药品的鸟。故选C。
