单选题One night, a little before nine o"clock, Dr. Johnson was answering a telephone call. He was asked to go and give an operation to a very sick boy at once. The boy was in a small hospital in Glens Falls, sixty miles away from Dr. Johnson"s city—Albany. The boy had hurt himself in a traffic accident. His life was in danger, but his family was so poor that they could not pay the doctor anything. After he heard all this, Dr. Johnson was driving carefully. He thought that he could get to the hospital before 12 o"clock. A few minutes later, the doctor"s car had to stop for a red light at a crossing. Suddenly a man in an old black coat opened the door of the car and got in. "Drive on" ,he said. "I"ve got a gun(枪). " "I"m a doctor," said Johnson. "I"m on my way to a hospital to operate on a very sick... " "Don"t talk," said the man in the old black coat. "Just drive. " A mile out of the town he ordered the doctor to stop the car and get out. Then the man drove on down the road. The doctor stood for a moment in the snow. A half hour, Dr. Johnson found a telephone and called a taxi (出租车). At the railway (铁路) station he learned that the next train to Glens Falls would not leave until 12 o"clock. It was after two o"clock in the morning when the doctor arrived at the hospital in Glens Falls. Miss Clarke, a nurse, was waiting for him. "I did my best," said Dr. Johnson. Miss Clarke said. "The boy died an hour ago. " They walked into the waiting room. There sat the man in the old black coat, with his head in his hands. "Mr. Shute," said Miss Clarke to the man," this is Dr. Johnson. He had come all the way from Albany to try to save your boy. "

单选题 H5N1 avian influenza, known commonly as bird flu, has killed at least 15 people across Asia and was confirmed in China on January 27. No human cases have been found in the mainland, but 13 of the country's 31 provinces, autonomous regions, and municipalities (直辖市) have reported the disease in poultry. The Chinese government has taken measures to prevent and control the disease. Poultry within 3 km of infected farms is to be killed and those within 5 km vaccinated (进行接种疫苗 ). Meanwhile, there will be constant monitoring and daily reports on the disease across the country, and increased production of bird flu vaccines. Among the Asian countries and regions affected by bird flu in animals, only Vietnam and Thailand have reported human cases. The people infected were reported to have caught the disease from poultry. While the World Health Organization (WHO) said there is "no proof of human-to-human transmission (传播)" of bird flu. The big fear is that the disease could combine with a human influenza virus (病毒) to create a deadly new disease that will kill millions of people across the globe. Many Asian farmers live closely with their animals and sell live chickens in the market. This greatly increases the possibility of human beings infected with bird flu. A spokesman of the WHO said that Asian countries affected by bird flu should introduce a more healthy way of raising and selling chickens. And the people there have to completely change their lifestyle and attitude towards animals. Here are some safety measures for people to stay healthy: Keep fit and well through regular exercise; Avoid infected poultry and infected people; Avoid eating raw or under-done poultry and eggs; Make sure there is always fresh air in your home; Cover your mouth and nose when coughing or sneezing; Wash your hands frequently.
