Mankind’s capacity to store the large amount of information in theworld has been measured by scientists. The study, published in the journal Science,calculates the amount of data stored in the world by 2007 was 295 exabytes. That’sequal to 1.2 billion average hard drives. “If we were to take all theinformation and store it in books, we could cover the entire area of the US orChina in 3layers of books,” Dr. Martin Hilbert of the University of SouthernCalifornia told BBC’s Science in Action. By 2007, 94% of stored information was kept digitally. The same informationstored digitally on CDs would create a stack of discs that would reach beyondthe moon, according to the researchers. The fastest growing area of information operation has been computation.During the two decades the survey covers, global computing capacity increased by58% per year. These numbers may sound large, but they are still dwarfed (相形见绌) by the information processing and storage capacity of a humanbeing. This study looked at the world as a whole, but the scientists saythat it does show that the “digital divide” between rich and poor countries isgrowing. Despite the spread of computers and mobile phones, the capacity toprocess information is becoming more unequal. In 2002, people in the developedworld could communicate eight times more information than people in thedeveloping world. Just five years later, in 2007, that gap had nearly doubled,and people in richer countries had 15 times more information carrying capacity. 1. Before 2007, most stored information was kept in the form of______. A. pictures B. words C. digits D. sounds 2. What can we learn from Paragraph 3? A. Global computing capacity to store information is more powerfulthan mankind’s capacity. B. Mankind’s capacity to store information is more powerful thanglobal computing capacity. C. Global computing capacity to store information is increasingslowly. D. Global computing capacity increased by 58% per year during thelast 30 years. 3. What do we know about the “digital divide”? A. Digits are divided into several parts. B. Different countries have different forms of digitalinformation. C. The capacity to process information is equal among countries. D. Rich countries can communicate more information than poorcountries. 4. The word “gap” can be best replaced by the word ______. A. blank B. difference C. break D. shape 5. Which of the statements is wrong according to the text? A.By 2007, 94% of stored information was kept digitally. B The fastest growing area of information operation has beencomputation. C.The strdy shows that the “digital divide” between rich and poor countries is not growing. D. Despite the spread of computers and mobile phones, the capacityto process information is becoming more unequal.
