Their cheery song brightens many a winter's day. But robins are in danger of wearing themselves out by singing too much. Robins are singing all night一as well as during the day, British-based researchers say.
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.
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.
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.
【1】According to Dr Dominoni's study, what cause 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.
【2】What is the researchers' concern over the increase of birds' song output?
A. The environment might be polluted.
B. The birds' health might be damaged.
C. The industry cost might be increased.
D. The people's hearing might be affected.
【3】What does the underlined word "nocturnal" in Paragraph 5 mean?
A. Active at night. B. Inactive at night.
C. Active during the day. D. Inactive during the day.
【4】Why do some birds thrive in noisy environments?
A. Because there are fewer dangers.
B. Because there is more food to eat.
C. Because there is less light pollution
D. Because there are more places to take shelter.
【答案】
【1】B
【2】B
【3】A
【4】A
【解析】
试题分析:本文主要介绍了一项研究调查的结果,由于人类制造的光线问题,越来越多的鸟类如知更鸟在晚上也会唱歌,这极大地影响了鸟的健康。
【1】B 细节理解题。根据文章第二段的David Dominoni, of Glasgow University, said that light from street lamps, take away signs and homes is affecting the birds' biological clock, leading to them being wide awake可知选择B。
【2】B 细节理解题。根据文章Singing is a costly behaviour and it takes energy. So by increasing their song output, there might be some costs of energy."可知,唱歌唱得越多,就会损耗更多的能量,故选择B。
【3】A 词义辨析题。根据上文的And it is not just robins that are being kept awake by artificial light. Blackbirds and seagulls are also being可知乌鸦和海鸥情况也一样,也就是说这两种鸟晚上也唱歌,故选择A,指晚上很兴奋。
【4】A 细节理解题。根据文章最后一段的It is thought that they are capitalising on their predators(天敌)fleeing to quieter areas.可知,它们的天敌都去了安静的地方,故选择A,指在这些工业区,天敌更少,也就是危险更少。

People select news in expectation of a reward. This reward may be either of two kinds. One is related to what Freud calls the Pleasure Principle, the other to what he calls the Reality Principle. For want of better names, we shall call these two classes immediate reward and delayed reward.
In general, the kind of news which may be expected to give immediate reward are news of crime and corruption, accidents and disasters, sports, social events, and human interest. Delayed reward may be expected from news of public affairs, economic matters, social problems, science, education, and health.
News of the first kind pays its rewards at once. A reader can enjoy an indirect experience without any of the dangers or stresses involved. He can tremble wildly at an axe-murder, shake his head sympathetically and safely at a hurricane, identify himself with the winning team, laugh understandingly at a warm little story of children or dogs.
News of the second kind, however, pays its rewards later. It sometimes requires the reader to tolerate unpleasantness or annoyance — as, for example, when he reads of the threatening foreign situation, the mounting national debt, rising taxes, falling market, scarce housing, and cancer. It has a kind of “threat value.” It is read so that the reader may be informed and prepared. When a reader selects delayed reward news, he pulls himself into the world of surrounding reality to which he can adapt himself only by hard work. When he selects news of the other kind, he usually withdraws from the world of threatening reality toward the dream world.
For any individual, of course, the boundaries of these two classes are not stable. For example, a sociologist may read news of crime as a social problem, rather than for its immediate reward. A coach may read a sports story for its threat value: he may have to play that team next week. A politician may read an account of his latest successful public meeting, not for its delayed reward, but very much as his wife reads an account of a party. In any given story of corruption or disaster, a thoughtful reader may receive not only the immediate reward of indirect experience, but also the delayed reward of information and preparedness. Therefore, while the division of categories holds in general, an individual’s tendency may transfer any story from one kind of reading to another, or divide the experience between the two kinds of reward.
What news stories do you read? | |
Division of news stories | ● People expect to get 【1】 from reading news. ● News stories are roughly divided into two classes. ● Some news will excite their readers instantly while others won’t. |
【2】of the two classes | ● News of immediate reward will seemingly take their readers to the very frightening scene without actual 【3】. ● Readers will associate themselves closely with what happens in the news stories and【4】similar feelings with those involved. |
● News of delayed reward will make readers suffer, or present a【5】to them. ● News of delayed reward will induce the reader to 【6】for the reality while news of immediate reward will lead the reader to 【7】from the reality. | |
Unstable boundaries of the two classes | ● What readers expect from news stories are largely shaped by their 【8】. ● Serious readers will both get excited over what happens in some news stories and【9】themselves to the reality. ● Thus, the division, on the whole, 【10】on the reader. |
