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 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.
