Scientists say a huge percentage of bird species are in danger because their habitats, or homelands, are disappearing.
Traditional migration paths take birds through countries that are not protecting the places for birds to stop, rest and feed. The scientists studied the migration or flight paths of almost 1,500 species. They decided that 91 percent of them passed through dangerous areas.
The major danger for migratory birds is development. Buildings and pavements have covered the places where birds stop and feed as they move from one part of the world to another. One of the scientists who worked on the study says “Many of these important places have been lost to land reclamation (开垦) because of urban, industrial and agricultural land expansion”.
The problem, according to scientists, is that many of these small birds die along their migration paths because they don’t have a safe place to feed and rest. There is no place to restore their energy for the next part of their journey. Countries in North Africa, Central Asia and those along the coasts of East Asia are having the most difficult time in protecting land. The scientists say these countries do not have enough areas that are safe for birds. One species that doesn’t exist now is the Eskimo curlew. “Our world gets poorer every time we lose a species,” one of the scientists says.
The researchers say countries need to work together and come up with safe stopping areas for birds that pass through their boundaries. For example, one country might have preserved safe zones for migrating birds. But a neighbor country might not. A bird might die.
One scientist who is not connected with the report tells Los Angeles Times that while some habitats are changing, more work can be done to make urban areas safe for birds.
He says small changes, like planting more native plants or keeping cats out of the areas birds would be likely to use, could make a big difference.

At the age of 14, James Harrison had a major chest operation and he required 13 units (3.4 gallons) of blood afterwards. The blood donations saved his life, and he decided that once he turned 18, he would begin donating blood as regularly as he could.
More than 60 years and almost 1,200 donations later, Harrison, whose blood contains an antibody (抗体) that has saved the lives of 2.4 million babies from miscarriages (流产), retired as a blood donor on May 11. Harrison’s blood is valuable because he naturally produces Rh-negative blood, which contains Rh-positive antibodies. His blood has been used to create anti-D in Australia since 1967.
“Every bottle of anti-D ever made in Australia has James in it,” Robyn Barlow, the Rh program director told the Sydney Morning Herald. “It’s an amazing thing. He has saved millions of babies. I cry just thinking about it.” Since then, Harrison has donated between 500 and 800 milliliters of blood almost every week. “I’d keep going if they let me,” Harrison told the Herald. His doctors said it was time to stop the donations. They had already extended the age limit for blood donations for him, and they’re cutting him off now to protect his health.
Harrison’s retirement is a blow to the Rh treatment program in Australia. Only 160 donors support the program, and finding new donors has proven to be difficult. But Harrison’s retirement from giving blood doesn’t mean he’s completely out of the game. Scientists are collecting and cataloging his DNA to create a library of antibodies and white blood cells that could be the future of the anti-D program in Australia.
1.Why did James Harrison decide to donate blood as regularly as he could?
A.Because he wanted to be a celebrity.
B.Because he was saved by the blood donations when he was young.
C.Because his blood is valuable.
D.Because the Rh treatment program in Australia need him.
2.What can we learn from the underlined sentence in paragraph 3?
A.Robyn Barlow was sad because millions of babies suffer from blood disease.
B.Robyn Barlow was worried because Harrison may die of losing too much blood.
C.Robyn Barlow was moved by Harrison’s donations.
D.Robyn Barlow was frightened by Harrison’s crazy behavior.
3.What can we infer from the last paragraph?
A.Harrison’s retirement will not affect the Rh program.
B.After Harrison’s retirement, the Rh program will fail.
C.Harrison’s influence to the Rh program will still exist after his retirement.
D.A library has been built for the study of Harrison’s DNA .
4.Which word can best describe Harrison?
A.Patient. B.Diligent.
C.Talented. D.Devoted.

The United States government list of endangered species includes alligators, tigers, grizzly bears, some kinds of whales, and over three dozen species of butterflies. What has led to the scarcity of these animals, which may become extinct without vital protection?
One important factor is that many animals have been widely hunted and killed for food and for their beautiful skins. In accordance with the Endangered Species Act, it is illegal in the United States to hunt, sell, or collect endangered species. Thus, an expensive fur coat made from a tiger killed in Asia cannot be legally sold to a wealthy matron in New York or San Francisco.
Some predators, which kill useful, more common animals, are threatened by farmers who are concerned that predators will carry off chickens and young sheep, and because of this fear they trapped and killed them.
The butterfly is an accidental victim of man’s effort to control his environment, For a long time collectors have searched for unusual specimens for their colorful butterfly collections; now, there is an additional, more Serious threat—widespread use of dangerous pesticides which farmers apply to their crops to control harmful insects.
With various animals being killed for food, for decoration, and for the protection of domesticated animals, or dying because of unfortunate contact with human environments, it is not surprising that some are becoming scarce, that the number of species on the endangered list is growing every year. Man is discovering that his world includes the other animals in it, and one can only hope his discovery is not coming too slowly or too late.
