举一反三
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. |
F. These drugs are made of molecules called proteins.
G. Medicine comes in lots of different packages.
A.come up | B.come out | C.come off | D.come across |
小题1:
Most fitness advice is aimed at a general audience. But if you’re an older adult, the International Council on Active Aging (ICAA) has some tips for seniors to get started and keep them at the top of their game.
小题2: Talk with your doctor about getting permission to begin a fitness program and making any changes to suit your situation.
小题3: Before starting, pick a program you’ll enjoy, so you’ll do it regularly. Check out the facility and the staff. Is the place friendly? Can you change clothes comfortably? Are facilities easily accessed?
Determine your participation style. Choose what’s best for you — a class or going solo? Morning or night hours? 小题4:
Start slowly. Most people are overeager and sometimes overdo it. Record a baseline of your regular activities and determine a reasonable plan.
Make a date. Find a friend to exercise with you and keep you motivated.
Set specific short-term and long-term goals. Plan for activity in your day and make it a priority.
Remind yourself what your goals are. If it hurts, don’t do it. 小题5: And once you’ve reached your goal, treat yourself for the good job you’ve done, so it will encourage you to continue.
A.Make a list. |
B.Exercise Tips for Seniors to Start a Healthy Game |
C.Know your choice. |
D.Learn to work around pain, not through it. |
