Mass Migration

Look up at the sky one autumn day and you might see a flock of birds in V-formation. 1. All summer, they have lived in the north where they made their nests, laid their eggs, hatched, and raised their young. Soon, snow and ice will cover all their northern breeding grounds, so they must migrate south where food is easier to find. It is necessary to create worldwide bird sanctuaries(保护区) before many of these species become extinct(灭绝).

2. The Arctic tern travels 10,625 miles from one polar region to the other. This may be the longest migration of any animal on Earth. Not all birds migrate. Some are able to adapt to winter by changing their diets. 3. For most species, however, it is easier to migrate to climates that are not as severe.

Somehow, migrating birds know exactly where they are going and how to get there. It is amazing to think about how birds are able to return to the same place year after year. 4. Other scientists believe that migratory birds navigate by following certain coastlines, mountains, and rivers. However they do it, these amazing creatures always arrive in the right place at the right time. In the spring, they return to their nesting grounds up north to lay their eggs and care for their young.

It is important for the people of the world to protect the estuaries (河口)and wetlands . 5. With so many species of birds’ habitats threatened worldwide, our children may never be able to enjoy the beauty of these migrating wonders.

A. These birds stay in the same place all year.

B. They are important to endangered species.

C. Some birds travel great distances, crossing entire continents and oceans.

D. They are flying south where there is warmth and food during the winter.

E. Birds fly around the world according to the weather year around year.

F. Some scientists think it is possible for birds to use the stars to find their way.

G. The birds that migrate south in winter return to different places when weather is warm.

 

After a year of being prepared, Laura Dekker can’t wait to set sail .Last August ,the Dutch government decided that Laura Dekker was too young to take on the challenge of sailing around the world alone. But after a year of preparing herself , Laura has been allowed to sail.

”I was so happy I almost jump into the water,” Laura said , after learning of the court’s judgement. She was born on a yacht(游艇) in the South Pacific ,and now lives with her father in a boat. When Dutch child protection groups first heard about her plan to sail alone , they stopped her from doing so .

Since the decision, though, Laura had been preparing with her father to persuade the courts that she was ready. Last week she received the books and other materials she would need for school while she was at sea. She added safety equipment to a new, big ship. And she took her first aid course to learn several survival skills, like how to put out fires on the boat, take care of her own injuries and deal with lack of sleep. She also planned a safer course --- adding alternate routes(备用路径) to avoid pirate(海盗) attacks, and planning a course that would have her on dry land as she moved from port to port across the world.

Laura is using a larger and more safer boat. If she finished successfully in less than two years, she will take the title from current record-holder Jessica Watson, of Australia, who was 16 when she completed the journey.
