Now that so much data is stored and circulated electronically, a library might seem to be a slightly outdated concept. However, a huge proportion of the world’s information and learning is still not available electronically, so libraries retain their importance for research and study. It is should also be remembered that libraries store books, inscriptions(铭文), and documents that are beautiful, and valuable not just for their contents, but also for their historic and artistic significance.
British Library (United Kingdom, London)
The British Library was created by Act of Parliament in 1972. Previously, the library had been part of the British Museum, where the famous circular reading room had accommodated researchers including Karl Marx, who worked on Das Kapital there, as well as Oscar Wilde and Mohandas Gandhi. The British Library is now housed in a new building in St. Pancras, London, where its treasures include two Gutenberg Bibles, the Lindisfarne Gospels, and one of Leonardo da Vinci’s notebooks.
Library of Congress(United States, Washington, D. C)
Founded in 1800 with the private collection of Thomas Jefferson, the Library of Congress is in fact the USA’s National Library, although only Congress members and employees can borrow books. It receives two copies of everything published in the United States. The Library of Congress was burned by the British Army in 1812, and severely damaged by fire again in 1851. The collection includes many rare books and drawings, and two Stradivarius violins.
National Library of China(Beijing)
Holding over 30 million books and documents, and visited by over five million people every year, this is the largest collection of Chinese writing in the world, and the largest library is Asia. It includes Chinese inscriptions on bone, stone, and tortoise shell which date back as far as the sixteenth century BC, and some of the oldest printed documents in existence as well as items in foreign languages and many rare books.

If humans ever settle on Mars, they will need water. There is just one problem---there seems to be only huge sheets of ice. Luckily, we know how to drill(钻孔） ice for water. Such methods are already used in Antarctica, and researchers now think they could get them to work on the Red Planet, too. The atmosphere of Mars is too dry to make extracting water vapour from it possible. So ice seems the best bet. But the obvious ice sheets are in the unlivable polar ice caps and would be difficult to reach for drilling.
However, in 2018, at the edge of the cliffs, NASA's Mars Reconnaissance Orbiter spotted relatively accessible water ice that is probably at least 130metres thick and covered in just a few metres of rock and dust. These may be the best place to get the water needed for future exploration of the planet.
The drilling techniques needed have already been developed for cold areas on Earth where we need to melt buried ice for water. In the early 1960s the US Army used a type of subsurface reservoir(水库)called Rod Well, in army camps in Greenland. The method works by drilling through the ground into the ice, melting the ice to create a pool, and then pumping water up. By supplying heat continuously, they create a reservoir and a steady water supply. It has been used in remote areas such as the Amundsen-Scott South Pole Station Stephen Hoffman at the Aerospace Corporation in Texas and his colleagues simulated(模拟)how a Rod Well would do on Mars. They found that with the power of 9 kilowatts (千瓦)to melt ice, it could in theory produce about 380 litres of water each day and maintain a reservoir of constant size at the bottom of a borehole(钻孔). That is close to the average daily water use each person in the US, but about 10 times what each astronaut on the International Space Station uses daily.
1.Which of the following can replace the underlined word "extracting" in the first paragraph ?
A.obtaining B.protecting
C.Preventing D.choosing
2.Why does the author mention the Rod Well in Paragraph 3?
A.To explain how water ice is drilled on Mars.
B.To tell about the history of water ice drilling techniques.
C.To prove the importance of water ice drilling techniques
D.To show techniques for drilling water wells in Martian ice exist.
3.On average, how much water does an astronaut on the International Space Station use daily?
A.10 litres B.38 litres
C.160 litres D.380 litres
4.What would be the best title for the text?
A.Preparing to settle on the Red Planet one day.
B.Finding water on the Red Planet for survival.
C.Using some ways to create a livable environment on Mars.
D.Drilling water wells in Martian ice to survive on Mars.
