Guide to Stockholm University Library

Our library offers different types of studying places and provides a good studying environment.

Zones

The library is divided into different zones.The upper floor is a quiet zone with over a thousand places for silent reading,and places where you can sit and work with your own computer.The reading places consist mostly of tables and chairs.The ground floor is the zone where you can talk.Here you can find sofas and armchairs for group work.

Computers

You can use your own computer to connect to the wi-fi specially prepared for notebook computers; you can also use library computers,which contain the most commonly used applications,such as Microsoft Office.They are situated in the area known as the Experimental Field on the ground floor.

Group-study Places

If you want to discuss freely without disturbing others,you can book a study room or sit at a table on the ground floor.Some study rooms are for 2-3 people and others can hold up to 6-8 people.All rooms are marked on the library maps.

There are 40 group-study rooms that must be booked via the website.To book,you need an active University account and a valid University carD. You can use a room three hours per day,nine hours at most per week.

Storage of Study Material

The library has lockers for students to store course literature.When you have obtained at least 40 credits,you may rent a locker and pay 400 SEK for a year’s rental perioD.

Rules to be Followed

Mobile phone conversations are not permitted anywhere in the library.Keep your phone on silent as if you were in a lecture and exit the library if you need to receive calls.

Please note that food and fruit are forbidden in the library,but you are allowed to have drinks and sweets with you.

Alaska’s Arctic lakes now freeze later and melt earlier in the year than in 1950,leaving them easy to suffer water loss from evaporation(蒸发)and possibly adding to local warming,a new study finds.The winter ice season near Barrow,Alaska,is shorter than in 1950,researchers reported Jan.30 in the journal The Cryosphere.

Lake ice is also thinner each winter.The scientists surveyed 402 lakes on the North Slope,where permafrost (permanently frozen ground)and shallow lakes dominate the areA. In 2011,the lake ice was 38 percent thinner than in 1950,and 22 percent fewer lakes froze through to their bottoms.

“When we saw the actual numbers we were shocked at how dramatic the change has been,”lead study author Cristina Surdu,of the University of Waterloo in Canada,said in a statement.Surdu and her co-authors analyzed the changes in lake—ice thickness and ice cover with satellite images and climate model simulations(satellite images are only available from 1991).

The climate models suggest the Arctic lakes froze almost six days later and broke up about 18 days earlier in the winter of 2011 compared with the winter of 1950.“The changes in ice and the shortened winter affect Northern communities that depend on ice roads to transport goods,”Surdu saiD. For example,every winter,oil companies build roads over frozen lakes to carry supplies to Prudhoe Bay.

“The dramatic changes in lake ice may also contribute to further warming of the entire region,because open water on lakes contributes to warmer air temperatures,”Surdu saiD. The Arctic is warming twice as fast as the rest of the planet,for reasons that may include its layered atmosphere,which traps heat,and the loss of sea ice and snow cover,which help reflect the sun’s energy when present.

1.What does the text mainly tell us?

A. Arctic 1akes now freeze earlier and melt 1ater.

B. Alaska’s local warming is decreasing sharply.

C. Arctic lakes are losing ice.

D. Arctic lakes hold more flesh water than before.

2.According to the text,the great changes of Alaska’s Arctic lakes ________.

A. are totally beyond Surdu’s expectations

B. are completely within Surdu’s expectations

C. come as no surprise to Surdu and her co-authors

D. come as a great excitement to Surdu

3.How many days was the winter ice season of Arctic 1akes in 2011 shorter than that in 1950?

A. 6 days.

B. 12 days.

C. 18 days.

D. 24 days.

4.What is the last paragraph mainly about according to Surdu?

A. What reflects the sun’s energy.

B. How its layered atmosphere traps heat.

C. Why our planet is warming.

D. Why the Arctic region is becoming warmer.

Researchers in the US say they might have discovered how to fight against and even reverse some processes of ageing, at least in mice. Injecting the blood of young mice into the older ones improved their brainpower, a study found. Scientists at Stanford University plan to carry out trials in people in the hope that new treatments for dementia(痴呆症) can be developed.

“There are factors present in blood from young mice that can recharge an old mouse’s brain so that it functions more like a younger one,”says Dr. Tony from Stanford University School of medicine. In the study published in Nature Medicine, mice aged 18 months were given injections of the blood taken from mice aged 3 months. The injected mice performed better on memory tests than mice of the same age that had not been given the blood. Dr. Tony said it was not known whether the same was true of humans, but a trial was planned.

A research center in UK said the treatment restored certain aspects of learning and memory in mice, but was of unknown importance to humans. The research, while very interesting, did not test the type of brain damage that was seen in dementia, which is not a necessary consequence of ageing.

Meanwhile, two similar studies by a separate team have thrown more light on how young blood may benefit the old, in mice at least. A substance in the blood of mice previously shown to have an anti-ageing effect on heart muscle also improved brain cells, according to a Harvard team. The research, published in Science, found the blood factors encouraged the growth of brain cells in old mice, and restored their sense of smell. The same chemical also improved muscle power of aged mice, the researchers found.

1. The underlined word in paragraph 1 probably means _________.

A. change B. destroy

C. speed D. increase

2. Scientists in the US will test the discovery in humans with the aim of __________.

A. proving the possibility to live longer.

B. showing the importance of scientific research.

C. publishing the study in Nature Medicine.

D. treating an age-related disease successfully.

3.According to the studies, the blood from young mice benefits the old in certain ways except in_________.

A. memory B. muscle power

C. fur color D. brain cells

4.What’s the author’s attitude to the anti-ageing studies?

A. supportive B. objective

C. negative D. doubtful
