Question

A deadly strain of avian flu may have passed between people for the first time, experts believe.The avian influenza A (H7N9) virus is thought to have been transmitted between father and daughter in eastern China, according to research published online by the British Medical Journal (BMJ).

    The findings provide the strongest evidence yet of H7N9 transmission between humans since its discover in February, but its ability to transmit itself was deemed "limited and non-sustainable" by the Chinese researchers behind the study.At the end of June 133 cases had been reported, including 43 deaths. Most infections have been among people visiting markets, selling live birds or among those who had contact with live poultry（家禽） in the seven to 10 days before becoming ill.

The latest study examined the case of a 60-year-old father who regularly visited a live poultry market and became ill five to six days after his last visit in March. He was admitted to hospital with fever, cough and shortness of breath. Despite intensive care treatment he died of multiple organ failure on 4 May. His 32-year-old daughter, who was previously healthy, looked after him at his bedside before he was admitted to intensive care. She had no known exposure to live poultry before falling ill with a very high temperature, cough and fever. The daughter developed symptoms six days after her last contact with her father and was admitted to hospital where she died of multiple organ failure on 24 April.

Follow-up investigations(調(diào)查) uncovered almost genetically identical virus strains from each patient, suggesting transmission from father to daughter. Another 43 people were also tested who had had close contact with the father, daughter or both.

Dr Peter Horby, senior clinical research fellow at the Oxford University Clinical Research Unit in Hanoi, Vietnam, said of the study: "The most likely source of infection for the daughter was her father, during the period that she cared for him while he was ill. "He said “l(fā)imited person to person transmission had been reported for other strains like H5N1 , H7N7, and the pig origin flu virus H3N2. Those strains had been around for more than a decade but have not progressed any further down the path towards a world-wide virus.” “Limited human-to-human transmission of H7N9 virus is therefore not surprising, but strengthening to monitor it was still needed,” Dr Horby added.

5.D

【解析】

試題分析：本文是一篇關(guān)于H7N9禽流感在人際間傳播的一篇報道。研究人員通過對因患H7N9禽流感而死亡的一對父女的病例研究認為H7N9禽流感存在人與人之間傳播的可能，但是指出H7N9禽流感這種人傳人的效力很低，公眾沒有必要恐慌。

1.B主旨大意題。本文為科學研究類文章，開頭亮明主題，本文首句A deadly strain of avian flu may have passed between people for the first time, experts believe。然后圍繞這一話題敘述具體研究過程和發(fā)現(xiàn)，所以文章中心是：(H7N9) virus可能在人與人之間傳播。故B選項正確。

2.C推理判斷題。從文章最后一段The most likely source of infection for the daughter was her father, during the period that she cared for him while he was ill.可知32歲的女兒沒有接觸過活禽，但是在照顧父親六天后出現(xiàn)發(fā)燒等禽流感癥狀。所以她死亡的病因是和患禽流感的父親的密切接觸。故C選項正確。

3.D細節(jié)理解題。從末段Those strains had been around for more than a decade but have not progressed any further down the path towards a world-wide virus.”可知目前H7N9禽流感病毒大規(guī)模人傳人可能性不大。所以D選項正確。

4.B詞義猜測題。A被減少；B被認為；C被想起；D被發(fā)展。"limited and non-sustainable" 是H7N9病毒的特點，根據(jù)語境此處應(yīng)該是指研究人員認為H7N9病毒傳播的能力是有限的，非持續(xù)性的。故B選項正確。

5.D推理判斷題。從文章內(nèi)容我們可知這是一篇關(guān)于H7N9流感病毒的報道，所以文章應(yīng)該屬于醫(yī)學發(fā)現(xiàn)類文章。所以D選項正確。
