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.

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. “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. 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. 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.

For many people, the story of cottages — small vacation homes away from the city — is a deeply personal one. For some families, cottages have been the scene of reunions, vacations and family adventures for generations.
In North America, “cottaging（去乡间别墅度周末）” really began during the 19th century. At that time, crowds of people were moving from family farms to cities. Naturally, these people often felt a longing for the natural beauty of the countryside. Frequently located near lakes, in the mountains of woods, cottages provided a perfect solution.
Traditionally small and rustic (乡下风格的)，many cottages were once simple log（原木） homes without bathrooms, water or electricity. While in most cases that is no longer true, people still go to cottages in large numbers to escape the city and to enjoy “cottage life.”
Despite the peaceful setting, there is always plenty to do at a cottage. If you enjoy outdoor activities, try hunting, boating or hiking. Many cottages are located near a lake, so you have opportunities to go swimming, boating or sunbathing around. Enjoy a picnic with your family, or build a campfire to roast hot dogs. On rainy days, curl up(蜷曲) on a comfortable chair inside and read, or enjoy board games （棋类游戏） with your friends and relatives. Want to get out and explore? Take a tour of the lake in a motorboat, or visit one of the many small villages located nearby.
Many families rent cottages instead of owning them, but for those who do, there’s always work to be done. Wood must be chopped for the stove. Leaves need to be gathered and gardens taken care of. Since many cottages are old buildings, there’s usually something that needs to be fixed or painted.
The story of cottages is one of families, traditions and memories. Are you ready to try cottaging with your family?
【小题1】The underlined word “longing” in Paragraph 2 probably means “_________ ”.

Dorothea Shaw is 71 years old and nearly blind, and she chose to live alone far away from people. She lives in Belize — a county the size of Wales with a population only that of Swansea. Her home is at Gales Point, a tiny village which can be reached only by sea or air; after a 10-mile walk into the hills one finally reaches a piece of land and two small houses so hidden in the thick over-grown forest that only a handful of people know Dorothea is there.

She lives happily and totally alone – growing her vegetables, looking after her trees and dogs, cats and chickens. Once a month or so an old friend passes by with her food supplies and letters-usually including a letter from her sister in Scunthorpe and some bits of clothing from friends in Canada. Sometimes a local man will come and cut wood for her and a group of British soldiers will come across her and be greeted with the offer of a cup of coffee.

At night she lies in her tiny sleeping room with the dogs on the floor, the cats on the table near the typewriter and one of the hens settled down in a corner of the bookshelf, and listens for hours to any Spanish, English, German or French broadcasts she can find on her radio. Sometimes she gets lonely but most of the time the animals and the radio are company enough.

But recently the very things that she had tried to get free from so well have begun to catch up with her. The peace of the forest has been destroyed by the noise of earth-moving machines not many miles away. What she once only heard of distantly on the radio is now on her doorstep. Things began to change three years ago. The new main north-south road in Belize was cut through the forest only four or five miles away. “Now more people know I’m here.” She says. “I feel more and more uneasy each day.”
