Migrating Birds May Spread Flu

  Every year, residents of Kunming, Yunnan Province welcome thousands of black headed gulls(红嘴鸥)with food and happy laughter.The lovely white birds fly from Siberia to stay in the Dianchi area of the city in winter.But this year the white angels are no longer lovely in locals eyes, due to their fear of bird flu.

  Although scientists have not found the deadly virus in the birds, few people will dare to risk their lives to feed the birds this year.

  Across the world, wild migratory birds(候鸟)seem to have become public enemy number one.Since the deadly H5N1 bird flu virus was discovered not only in Asia but also as far away as Europe and Africa, migratory birds were regarded as the carriers.Geographically speaking(从地理上说), the spread of bird flu appears to be following the migratory routes of wild birds.Bird flu is a common disease among wild migratory birds.But the virus may change itself when transferred to fowls and human.

  Since the World Health Organization warned last month that migratory birds could carry the deadly H5N1 virus that causes bird flu, many countries, like China, have started tracking migratory birds and cleaning up poultry markets(家禽市场).China also cancelled(取消)all pigeon races last week.

  Scientists said that the migratory routes of wild birds are often far away from big cities.The risk of transferring(传染)the virus directly from wild birds to humans is very low.Scientists also warned that wild birds are shy creatures.They see you coming and fly away at once.But if a wild bird becomes easy to approach, people should be careful that it may be sick.

  There are already three areas hit by bird flu in the provinces of Hunan and Anhui and the northern region of Inner Mongolia, areas all on the migratory routes of wild birds.In the past two weeks China has reported three outbreaks of the H5N1 virus that killed 3800 chickens, ducks and geese(鹅).

请阅读下列科技新闻的信息:
A. One of the biggest science stories last year was the research on stem cells announced by South Korean scientist Hwang Woo-suk. But now it appears that the research was false. In June, Mr. Hwang reported that he and his team at Seoul National University had created eleven new stem cell lines.
B. Another major science story last year came from the United States. On December twentieth, a federal judge ruled that teaching “intelligent design” in public schools is a violation of the United States Constitution.
C. There was also news last year about the American space program. The American space shuttle(航天飞机) returned to the skies in July. Discovery and its seven-member crew made the first shuttle flight in two and one-half years. NASA had suspended shuttle flights following the deadly explosion of the shuttle Columbia in 2003.
D. Avian influenza(禽流感) was also a major science story last year. The H5N1 virus appeared in birds in Europe for the first time. Yet the only known human cases of the disease have been in East Asia. There have been about one hundred forty confirmed cases of bird flu since 2003. About half the people have died.
E. The World Health Organization advises patients to take a combination of four drugs to treat tuberculosis(肺结核). These four antibiotics must be taken for about six months to cure the disease. Some people, however, take the drugs only until they feel better. Discontinuing treatment is a mistake.
F. The researchers began the study in January, 2002. They called it SMART---Strategies for Management of Anti-retroviral Therapy. The scientists reached more than ninety percent of the target before they halted(停止) new enrollments last month. The researchers tested all the people for the level of CD-four cells in their blood. The researchers divided the patients into two groups.

【小题1】Card 1: One group stayed on continuous anti-retroviral therapy. They took their medicines every day. The other took them periodically. They took the drugs only when their CD-four count fell below two hundred fifty cells per cubic millimeter of blood.
【小题2】Card 2 : Judge John Jones said that intelligent design is not science. He said it is a version of Christianity. So to teach it in public schools violates the law that requires the separation of church and state. Supporters of intelligent design criticize the science of evolution.
【小题3】Card 3: Stem cells have the ability to grow into other cells. Science magazine published the report. The new lines were made from the eggs of eighteen women and skin cells from eleven other people.
【小题4】Card 4: Many of the victims had touched or been around infected farm birds. But health experts around the world began warning that the bird flu virus could change into a form that is passed from person to person.
【小题5】Card 5 : That explosion was the result of damage done to Columbia during its launch. A piece of lightweight protective material fell off the shuttle’s external fuel container. The object hit the shuttle at a high rate of speed and made a hole in one of the wings. This permitted extremely hot gases to enter the shuttle and destroy the spacecraft as it returned to the earth.
