The respiratory(呼吸系统) virus known as SARS has appeared to spread in the United States only to family members of health workers with close contact to a sick person.
On Thursday, the head of the Centers for Disease Control and Prevention said there might be a case of severe acute respiratory syndrome（综合症） spreading through the workplace.
Dr. Julie Gerberding said a suspected SARS virus patient who became ill after traveling to Asia might have infected a co-worker in Florida, which made her “very worried”.
So far, a dozen people—nine family members and three health workers—were infected after coming into close contact with the person with SARS. The rest of the 166 suspected American cases have something to do with people who were infected while traveling in Asia.
In the Gainesville, Fla. area, a 47-year-old woman was believed to have been infected at work by a 60-year-old woman who was the nation’s first suspected SARS case, said Tom Belcuore, director of the Alachua County health department.
Since the World Health Organization announced a worldwide warning last month about SARS, the United States has started infection control in hospitals and among families of suspected cases.
Florida officials said a school in Okaloosa County went through a cleaning after a 6-year-old boy suspected of having SARS appeared at school with slight symptoms. “Health officials are watching the boys’ contacts at school to make sure no one else is infected,” said Rob Hayes, health department spokesman, “The boy may have been infected from a family member,” Hayes said, “We immediately became aware of it and had the child sent home. He’s staying at home with his family until 10 days after symptoms disappear.”
The researchers guessed that the virus might have come from animals. However, the scientists have not ruled out the possibility that some other microbe might also help make SARS more serious or easier to catch.
【小题1】The best title for this text is .A．A Worldwide WarningB．Suspected SARS CasesC．What Is SARSD．Possible Spread of SARS in the USA【小题2】The writer wrote this text mainly to .A．discuss the danger of SARSB．report research result about SARSC．inform people of the spread of SARSD．explain to the readers what SARS is【小题3】How many cases of suspected SARS are there in the U.S.A. according to the text?
A. 166. B.178. C. 12. D. 181.D

(答案→)D 解析：文章是2003年非典爆发时的一则新闻，介绍了当时非典在美国的疫情和人们对于这种病毒的研究。【小题1】D 标题选择题。根据文章主要内容，当时社会各界都只是怀疑SARS开始在美国传播，而没有确切证据。【小题2】C 推断题。根据作者在文章中给出的信息和举出的病例，可以推断而知他是想通知美国的民众，非典的疫情可能已经在美国传播开来，所以选C【小题3】A 细节题。根据文章最后一段The rest of the 166 suspected American cases have something to do with people who were infected while traveling in Asia可知美国的非典疑似病例有166人。所以选A

这个解释是对的
