【题目】D

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.

【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。

1B 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

2B 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

3A 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。

4A 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。

【题目】SHANGHAI (Reuters) - A stampede(踩踏)killed at least 35 people and injured 43 during New Year's Eve celebrations in Shanghai, on the city's popular waterfront tourist attraction known as the Bund(外滩), authorities said.

The Shanghai government said that large crowds started to stampede in Chen Yi Square on the Bund just before midnight, with authorities working to rescue and aid the wounded.

It was not immediately clear what triggered the stampede. The official Xinhua news agency said many of the injured were students.

The government said on its official microblog(微博) that an inquiry had begun, with city leaders rushing to the scene and to hospitals to visit the injured. An emergency meeting would be held to ensure stepped-up safety measures were taken throughout the city.

Photographs on Weibo, the Chinese version of Twitter, showed densely packed crowds of revelers(狂欢者)along the Bund, which is lined with buildings from Shanghai's pre-communist period on the bank of the Huangpu River.

In some photographs, rescue workers were seen trying to resuscitate victims lying on the pavement while ambulances waited nearby.

Authorities had shown some concern about crowd control in the days leading up to New Year's Eve. They recently canceled an annual 3D laser show on the Bund that last year attracted as many as 300,000 people.

At dawn on Thursday, there were still small crowds of revelers trying to find taxis home and workers were clearing up trash strewn around the Bund. There was little sign of the mayhem that had broken out just hours earlier.

【题目】We live in a sweet world. The average American kid eats more than 20 teaspoons of sugar per day, and adults eat 50% more sugar today than they did in the 1970s. We all know that too much sugar isn’t good for you. But did we know it could be dangerous? A team of researchers at the University of Utah used mice to do a study on the bad effects of sugar. They found it could have serious effects on people’s health.

Sugar is found not only in sweets and candies, but also in many household items like pasta and crackers.

During the 58-week-long study, mice were fed a diet containing 25% more sugar. This percentage equals a healthy human diet along with three cans of soda daily. The team found that these mice were twice as likely to die as mice fed a similar diet without the sugar. Though the mice did not show signs of obesity or high blood pressure, male mice produced 25% fewer offspring (后代) than the other mice.

Scientists often use mice for research because they have a similar genetic (基因) structure to humans. “Since most substances (物质) that are dangerous in mice are also dangerous in people, it’s likely that those physical problems that cause those mice to have increased deaths also work in people,”says study author James Ruff of the University of Utah. Findings from this study show bad effects that are not as noticeable as weight gain or heart problems. Sugar can contribute to long-term changes in the body that can change development and even shorten lives.

Cutting sugar out of the American diet altogether may be difficult. But making the effort to control our nation’s sugar need will provide for a truly sweeter future.

【1】The study done by researchers aimed at learning about________

A. the advantages and disadvantages of sugar

B. the bad effects of sugar on people’s health

C. the genetic structure of mice

D. American’s eating habit.

【2】 According to the study, which of the following statements is wrong?

A. Sugar can even shorten lives.

B. Sugar’s bad effects are not noticeable.

C. Eating much more sugar can make mice put on weight and get high blood pressure.

D. Mice are more likely to die when fed a diet containing 25% more sugar.

【3】From the passage we can infer_______

A. sugar plays a very important role in Americans’ diet

B. kids eat more sugar than adults in America

C. the study on human beings lasted 58 weeks

D. the genetic structure of mice is totally different from that of people

【4】What’s the best title of the passage?

A. Living a sweet life B. Kids eat much more sugar

C. Genetic structure of humans D. Danger of too much sugar
