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.
