Change the form of the word if necessary:Born to SurfThe web From the Window contains poetry and literature from well-known writers across the global. There are thoughtful articles analyzing the state of the world we live in. There is (1)even a piece from the Secretary General of the United States, Kofi Annan. It may come (2)as some surprise to find out (3)that the editor of the magazine is a 12-year-old girl, Joy Nightingale.From the Window (4)won Joy Nightingale the first prize in the 1999 childnet Inter-national and Cable and Wireless awards. These are given (5)annually for the best use of the Internet (6)by and for young people. And (7)they highlight one of the most welcoming aspects of the (8)virtual world. Children have taken to the Internet as though they are born surfing.Perhaps this is (9)because adults have had to change their understanding of technology while children (10)simply accept it as natural. Whatever the reason, children can be found building websites and E-mailing friends (11)across the world while adults are (12)still asking: “Tell me again — where (13)exactly is cyberspace?”Of course there is growing (14)concern about the fact that children can travel far away from parental supervision in cyberspace. In (15)response , many parents have installed soft-ware packages which prevent (16)access to violent or pornographic websites. Childnet is taking a more positive line. The website is a gateway (17)to a world of education and entertainment.The rapid growth in Internet culture has (18)led analysts to speculate that society will soon be divided (19)between the “information rich”and “information poor”. For Childnet it is especially important that children at the margins of society through poverty or disability have the chance to take their (20)palce as equal citizens in the virtual world.IV. TranslationTranslate the following into Chinese:The possibility of a real market-style evolution of governance is at hand. In cyberspace, we’ll be able to test and evolve rules governing what needs to be governed — intellectual property, content and access control, rules about privacy and free speech. Some communities will allow anyone in: otherswill restrict access to members who qualify on one basis or another. Those communities that prove self-sustaining will prosper (and perhaps grow and split into subsets with ever-more-particular interests and identities). Those that can’t survive-either because people lose interest or get scared off-will simply wither away.一种真正的市场型管理模式很快成为可能。
