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 nightas 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 morenocturnal. 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.

1According 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.

2What 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.

3What 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.

4Why 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.

【题目】根据短文内容,从选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

In the world nothing is more important than health. If people took away our money, houses, cars, or even our clothes, we could still survive. 【1】 Then how can we keep healthy?

First of all, we should eat healthily. I usually avoid eating food high in fat, like French fries or cookies, which are junk food. 2 I only eat little meat. 3 It helps us build a strong body. Regular exercise is an important part of keeping me healthy. In addition, I think friends are an important part of one’s health. 4 I always feel better when I am with friends than when I am alone. When I am with my friends, I always laugh. Laughing is also an important part of health. It is good to stay with my friends.

By eating properly and exercising regularly, I can keep my body at a proper weight and keep healthy. By spending time with my friends, I can keep my mind as well as my body happy. These things sound easy to do, but not many people can manage them. 5

A.What’s more, taking exercise is very important.

B.Some people appear fat because they often eat too much.

C.I think a strong will is necessary if we want to keep fit.

D.I eat a lot of vegetables and fresh fruits which are full of vitamins.

E.There are some people who like staying alone, but they keep healthy.

F.But if our health were taken away, we could surely die.

G.Many studies show that people with few friends often get sick.
