Dozens of honey bees, which usually feed on wild flowers after leaving their hives (蜂房) in the campus gardens, were tricked into the cottage to feed from an artificial flower. Only one bee was allowed in at a time, and their visits to artificial flowers were videoed and timed under different fan speeds, which mimicked (模拟) calm and windy days.
But the rearchers are trying to help them: it is a controlled experiment that reveals how hi
gh wind speeds significantly reduce the efficiency of their feeding.
With no wind, the bees on average took nectar (花蜜) from 5.45 flowers during their 90-cond time trial. When wind speeds were incread, this fell to an average of 3.73 flowers.
Rearchers also examined the indirect impact of higher winds by moving the flowers.
The findings reveal that, while flower movement did not appear to have an effect on the bees, the movement of air from the fans made them much more hesitant to take off from a flower, with time taken ranging from an initial 0.05 conds to 54 conds.
Georgia Hennessy, lead author of the rearch, said that one possible reason for the wind causing hesitancy was that small increas in wind speed reduced the bees’ body temperature, so they require longer to warm up the flight muscles required to take off.
“With wind speeds predicted to increa in the years ahead, understanding how we can help bees in a changing climate is becoming ever more pressing. Although we can’t do m
uch to control or stop the wind, we can take steps to reduce its impact on bees, such as placing hives in sheltered locations,” said Hennessy.
The UN’s Food and Agriculture Organization warned last year that the decline in global bee populations was a “threat to global food curity and diversity”.
Dave Goulson, professor of biology at the University of Susx, said:“Bees already face many pressures in the modern world, such as loss of habitats and exposure to pesticides (杀虫剂), and a great many are in decline. Coping with increasingly windy weather under climate change may be the final straw.”

【答案】1．C2．D3．C4．C
【解析】这是一篇说明文。文章主要介绍了一个关于风速对蜜蜂进食效率的影响的实验，进而引出蜜蜂当下所面临的困境，并引发对于如何解决这一问题的思考。
1．细节理解题。根据第一段“Dozens of honey bees, which usually feed on wild flowers after leaving their hives (蜂房) in the campus gardens, were tricked into the cottage to feed from an artificial flower. Only one bee was allowed in at a time, and their visits to artificial flowers were videoed and timed under different fan speeds, which mimicked (模

2．细节理解题。根据第六段“Georgia Hennessy, lead author of the rearch, said that one possible reason for the wind causing hesitancy was that small increas in wind speed reduced the bees’ body temperature, so they require longer to warm up the flight muscles required to take off.(这项研究的主要作者Georgia Hennessy说，风导致蜜蜂迟疑的一个可能原因是风速的小幅增加降低了蜜蜂的体温，因此它们需要更长的时间来预热起飞所需的飞行肌群)”可知，降低的体温导致蜜蜂从一朵花到另一朵花的迟疑。故选D。
3．细节理解题。根据最后一段的“Coping with increasingly windy weather under climate change may be the final straw.(应对气候变化下日益多风的天气可能是最后一根稻草)”可知，应对风变多的天气是最后的办法，故选C。
4．主旨大意题。文章内容，尤其第一段本“Dozens of honey bees, which usually feed on 新视野大学英语mp3
