A Guide to the Library's Facilities(设备)

To use or reserve the facilities of the library, follow the procedures given at the circulation desk.

    Group Study Rooms (2F)

Students and teaching staff can use these rooms for group study. Students are advised to use unlocked rooms (3 rooms for 2 people, 2 rooms for 4 people) available for free. When you use locked rooms (2 rooms for 4 people, 1 room for 10 people), you need to go through reservation procedures at the circulation desk. These rooms are available for group discussion.

    Lu Xun is one of the greatest Chinese writers of the 20^th century. Besides his famous stories, he also wrote many influential articles about the living conditions of Chinese people.

    Born in 1881 to a wealthy family, Lu Xun had a happy childhood. In 1893, however, his grandfather, a senior government official, was put into prison for taking money. At the same time, his father became seriously ill. From that time on, his family were no longer accepted by their relatives and friends. These early experiences greatly influenced his writing.

    By the time Lu Xun arrived in Nanjing to study at university in 1899, he already believed that Chinese society had to change and become modern. In 1902 he went to study in Japan. There, he began writing articles for several Chinese student magazines. He showed a gift for writing and translating and he even wrote several books, although none was popular. He returned to China in 1909 because he was in need of money.

    After working for several years as a teacher in Beijing, Lu Xun again returned to writing. In 1918, he wrote his famous short story Diary of a Madman. It was the first Chinese novel published using the everyday language that people spoke, which helped make it a great success. This, together with his novel The True Story of Ah Q

    Rivers are earthly arteries(要道) for the nutrients, deposits and freshwater that sustain healthy, diverse ecosystems. Their influence extends in multiple dimensions—not only along their length but below­ground to aquifers(蓄水层) and periodically into nearby floodplains.

    They also provide vital services for people by fertilizing agricultural land and feeding key fisheries and by acting as transportation corridors. But in efforts to ease ship passage, protect communities from flooding, and draw off water for drinking and irrigation, humans have increasingly constrained and broken these crucial water ways. “We try to control rivers as much as possible,” says Gunther Grill, a hydrologist at McGill University.

    In new research published in May in Nature, Grill and his colleagues analyzed the barriers to 12 million total kilometers of rivers around the world. The team developed an index(指数) that evaluates six aspects of connectivity—from physical fragmentation (by dams, for example) to flow regulation (by dams or levees) to water consumption—along a river's various dimension. Rivers whose indexes meet a certain threshold(临界值) for being largely able to follow their natural patterns were considered free­flowing.

    The researchers found that among rivers longer than 1,000 kilometers (which tend to be some of those most important to human activities), only 37 percent are not blocked along their entire lengths. Most of them are in areas with a minimal human presence, including the Amazon and Congo basins and the Arctic. On the contrary, most rivers shorter than 100 kilometers appeared to flow freely—but the data on them are less comprehensive, and some barriers might have been missed. Only 23 percent of the subset of the longest rivers that connect to the ocean are uninterrupted. For the rest, human infrastructure is starving estuaries(河口) and deltas (such as the Mississippi Delta) of key nutrients. The world's estimated 2.8 million dams are the main cause, controlling water flow and trapping deposits.

    The new research could be used to better understand how proposed dams, levees and other such projects might impact river connectivity, as well as where to remove these fixtures to best restore natural flow. It could also help inform our approach to rivers as the climate changes, says Anne Jefferson, a hydrologist at Kent State University, who was not involved in the work. Existing infrastructure, she says, “has essentially been built to a past climate that we are not in anymore and are increasingly moving away from.”

The giant panda,also {#blank#}1{#/blank#} (know) as panda bear or simply panda,is a bear native {#blank#}2{#/blank#} south central China.For the past many years,the giant panda  {#blank#}3{#/blank#}  (drive)out of the lowland areas where it once lived as a result of farming,deforestation and other {#blank#}4{#/blank#} (develop).Wild population estimates vary:one estimate shows that there are about 1,590 individuals {#blank#}5{#/blank#}(live)in the wild,while a 2006 study estimated that this figure could be as high as 2,000 to 3,000.Some reports also show that {#blank#}6{#/blank#} number of giant pandas in the wild is on the rise.

The Mona Lisa is one of the most famous paintings in the world. Painted by Leonardo da Vinci in the early 16th century, it has captivated audiences for centuries with its mysterious smile and masterful technique. 

The painting is housed in the Louvre Museum in Paris, France, and attracts millions of visitors each year. However, the Mona Lisa's history is not without controversy. There have been numerous attempts to steal or deface the painting, and its conservation has been a subject of great concern.

Leonardo da Vinci's use of sfumato, a technique that blends colors and tones seamlessly, gives the painting a soft and hazy appearance. The sitter's expression, which seems to change depending on the viewer's angle and mood, adds to the intrigue of the work.
