While the world’s flu fighters have concentrated on countering the H1N1 swine flu, bird flu H5N1 has quietly continued to take its toll on both poultry and humans. Last year, 17 countries,【C1】______from Germany to Japan, reported outbreaks of H5N1 in【C2】______poultry and wild birds;and the World Health Organization,【C3】______still says H5N1 causes a worldwide threat, recorded 72 human【C4】______, 32 of them fatal. The major outbreak, entering its eighth year, is【C5】______in the developing countries of Asia. Indonesia【C6】______accounted for 19 of the 32 H5N1 deaths) Vietnam, 【C7】______5. But there are signs of【C8】______.
The number of human deaths has been【C9】______since peaking at 79 in 2006. And fewer countries reported outbreaks in 2009 than in 2008.
Partnership researchers compared notes on the effectiveness of control measures. Scientists reported that carefully【C10】______killing can be just as effective as widespread killing, and less【C11】______. Others reported that reducing risk among those【C12】______backyard poultry has to be a community-wide effort, since changing the practices of【C13】______farmers has proven difficult.
In particular, Science Insider reported that a 3-year-old regional investigation network is making【C14】______in sorting out the role of wild birds. Some waterbirds【C15】______thought to be spreading the virus, such as the Asian openbill stork, are now known to quickly die of H5N1 infection, Wiriyarat says. But passerine (燕雀类的) species, or perching birds, are apparently【C16】______the virus without ill effects, says an Asian zoologist. He also adds that there is a high【C17】______of outbreaks in poultry and passerine movements.
Wiriyarat says it is still【C18】______what is causing the outbreak, whether there is a natural storage for H5N1, and how the virus is【C19】______between domestic and wild birds. But while that research continues, the most effective way to reduce the amount of virus in【C20】______is to control outbreaks in poultry, he says. [br] 【C9】
选项
A、climbing
B、rising
C、remaining
D、dropping
答案
D
解析
动词辨析题。根据句意,人类死亡病例自从2006年已经达到顶峰值79例,由此可知这个数值不可能再上升了,那么应该是下降,因此D)dropping正确。A)climbing“攀升”,B)rising“上升”和C)remaining“保持”都不符合语义。
