David Dominoni,of Glasgow University,said that light from street lamps,takeaway signs and homes is affecting the birds’ biological clocks,leading to them being wide awake when they should be asleep. Dr Dominoni,who is putting cameras inside nesting boxes to track sleeping patterns,said lack of sleep could put the birds’ health at risk.His study shows that when robins are exposed to light at night in the lab,it leads to some genes being active at the wrong time of day.And the more birds are exposed to light,the more active they are at night. A B He told people at a conference,“There have been a couple of studies suggesting they are increasing their song output at night and during the day they are still singing.Singing is a costly behaviour and it takes energy.So by increasing their song output,there might be some costs of energy.” And it is not just robins that are being kept awake by artificial light.Blackbirds and seagulls are also being more nocturnal.Dr Dominoni said,“In Glasgow where I live,gulls are a serious problem.I have people coming to me saying ‘You are the bird expert.Can you help us kill these gulls?’.During the breeding(繁殖)season,between April and June,they are very active at night and very noisy and people can’t sleep.” Although Dr Dominoni has only studied light pollution,other research concluded that robins living in noisy cities have started to sing at night to make themselves heard over loud noise. A B However,some birds thrive(兴旺) in noisy environments.A study from California Polytechnic University found more hummingbirds in areas with heavy industrial machinery.It is thought that they are capitalising on their predators(天敌)fleeing to quieter areas. 【语篇导读】本文为议论文。光污染使知更鸟等鸟类的生物钟发生了紊乱,错把有人造光的夜间当成白天而高歌,从而严重影响这些鸟类的健康。然而,像蜂鸟这样的鸟在嘈杂的环境中却更加兴旺。 A B 6.According to Dr Dominoni’s study,what causes robins to sing so much? A.The breeding season. B.The light in modern life. C.The dangerous environment. D.The noise from heavy machinery. 解析:细节理解题。由第二段中的“...light from street lamps,takeaway signs and homes is affecting the birds’ biological clocks,leading to them being wide awake when they should be asleep.”可知,街灯、外卖店的招牌和住宅产生的人造灯光会影响鸟的生物钟,导致它们在本应睡眠的夜间十分清醒。故B项正确。 答案:B
