Next time you feel the flu coming on, think twice before reaching for painkillers—they could do more【C1】________than good. With the flu season【C2】________way across Europe and North America, millions will be taking flu【C3】________, which commonly include painkillers. The general【C4】________advice in the UK and the US is to take painkillers. But al-though painkillers can make you feel better they al-so lower fever, which can make the virus【C5】________.
The first analysis of the effect of this on the【C6】________shows that painkillers taken at current levels to【C7】________fevers could cause 2, 000 flu deaths each year in the US alone. Fever is thought to be a【C8】________against viruses, because many viruses find it hard to【C9】________above our normal 37 °C. Some studies have shown that lowering fever may【C10】________virus-related infections and increase the amount of virus we can【C11】________on to others.
To find out what【C12】________this might have on a flu epidemic, David Earn and his colleagues【C13】________to a 1982 study which showed that fer-rets, a【C14】________animal model for human flu produced more【C15】________flu virus if their fevers were lowered with painkillers. Earn’s team used these findings to estimate how much more virus people with【C16】________flu might produce if their fevers were【C17】________.
With the help of a mathematical model, Eam’s team【C18】________their estimates to the number of people a year in the US who get flu,【C19】________fever and take the drugs. They found that painkillers as used in the US could be increasing the【C20】________of ordinary winter flu by up to 5 per cent.
【C15】
选项
A、monthly
B、seasonal
C、yearly
D、weekly
答案
B
解析
文章第1段提过flu season,最后一段也说到了winter flu,流感病毒通常为季节性传播,据此可判断空格处应选择B项seasonal。文种提到每年或一年(如第2段和最后一段),那是指对一整年的流感人数或死亡人数的统计,而不是指一年的流感病毒,所以排除C项yearly。文中没有提及每月或每周的流感病毒情况,因此也可排除A项monthly和D项weekly。
