阅读理解 All over the world, libraries have begun the Herculean task of making faithful digital copies of the books, images and recordings that preserve the intellectual effort of humankind. For armchair scholars, the work promises to bring such a wealth of information to the desktop that the present Internet may seem amateurish in retrospect. … Librarians see three clear benefits to going digital. First, it helps them preserve rare and fragile objects without denying access to those who wish to study them. The British Library, for example, holds the only medieval manuscript of Beowulf in London. Only qualified scholars were allowed to see it until Kevin S. Kiernan of the University of Kentucky scanned the manuscript with three different light sources (revealing detail not normally apparent to the naked eye) and put the images up on the Internet for anyone to peruse (阅览). Tokyo’s National Diet Library is similarly creating highly detailed digital photographs of 1,236 woodblock prints, scrolls and other materials it considers national treasures so that researchers can scrutinize them without handling the originals. A second benefit is convenience. Once books are converted to digital form, patrons can retrieve them in seconds rather than minutes. Several people can simultaneously read the same book or view the same picture. Clerks are spared the chore of reshelving. And libraries could conceivably use the Internet to land their virtual collections to those who are unable to visit in person. The third advantage of electronic copies is that they occupy millimeters of space on a magnetic disk rather than meters on a shelf. Expanding library buildings is increasingly costly. The University of California at Berkeley recently spent $46 million on an underground addition to house 1.5 million books – an average cost of $30 per volume. The price of disk storage, in contrast, has fallen to about $2 per 300-page publication and continues to drop.1.The best title for this passage would be __________.A.Three Benefits of LibrariesB.Libraries Going DigitalC.Space-saving E-learningD.Security of Electronic Reading2.Which paragraph(s) in the text offer(s) further explanation of the central idea?A.Paragraphs 2, 3 and 4B.Paragraphs 3 and 4C.Paragraphs 2 and 4D.Paragraph 43.Which one of the following is mentioned as the advantages of E-librariesA.Old manuscripts can be moved more easilyB.Materials can be examined without being touchedC.Fewer staff will be required in librariesD.Libraries will be able to move underground4.What does the word ‘scrutinize’ probably mean?A.keep for a whileB.reprintC.restoreD.examine carefully

BACD解析本文叙述的是图书馆数字化了之后对读者和管理员的好处。1.推理判断题 根据第一段可知，图书馆将会建立网上图书馆，这就意味着图书馆的数字化。2.推理判断题 文章第二三四段分别就三个优点进行了深层次的解析。因此选A。3.推理判断题 根据第三段可知管理员无需亲自把书放入书架了，这样就省的大量的员工，因此选C.4.词义猜测题 根据那句话的意思：有了网上浏览，省的读者花大量的时间仔细的寻找自己需要的书了。

就是这个解释
