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.
D. R. Gaul Middle School is in Union, Maine, a blueberry-farming town where the summer fair finds kids competing in pig scrambles(争夺) and pie-eating contests.
Gaul, with about 170 seventh- and eighth-graders, has its own history of lower level academic achievement. One likely reason: Education beyond the basic requirements hasn't always been a top priority(优先) for families who've worked the same land for generations. Here, few adults have college degrees, and outsiders(局外人) (teachers included) are often kept at a respectful distance.
Since 2002, Gaul's students have been divided into four classes, each of them taught almost every subject by two teachers. The goal: To find common threads across disciplines to help students create a big picture that gives fresh meaning and context to their class work -- and sparks(激发) motivation for learning.
Working within state guidelines, each team makes its individual schedules and lesson plans, incorporating non-textbook literature, hands-on lab work and field trips. If students are covering the Civil War in social studies, they're reading The Red Badge of Courage or some other period literature in English class. In science, they study the viruses and bacteria that caused many deaths in the war.
Team teaching isn't unusual. About 77 percent of middle schools now employ some form of it, says John Lounsbury, consulting editor for the National Middle School Association. But most schools use four- or five-person teams, which Gaul tried before considering two-person teams more effective. Gaul supports the team concept by "looping" classes (跟班) so that the same two teachers stick with the same teens through seventh and eighth grades. Combining teams and looping creates an extremely strong bond between teacher and student. It also, says teacher Beth Ahlholm, "allows us to build an excellent relationship with parents."
Ahlholm and teammate Madelon Kelly are fully aware how many glazed looks they see in the classroom, but they know 72 percent of their eighth-graders met Maine's reading standard last year -- double the statewide average. Only 31 percent met the math standard, still better than the state average (21 percent). Their students also beat the state average in writing and science. And in2006, Gaul was one of 47 schools in the state to see testing gains of at least 20 percent in four of the previous five years, coinciding roughly with team teaching's arrival.
