阅读理解：People in some countries cannot use their native language for Web addresses. Neither can Chinese speakers, who have to rely on pinyin. But last Friday, ICANN, the Web’s governing body, approved the use of up to 16 languages for the new system. More will follow in the coming years. The Internet is about to start using the 16 languages of the world. People will soon be able to use addresses in characters (字符) other than those of the Roman alphabet (字母表). The change will also allow the suffix (后缀) to be expressed in 16 other alphabets, including traditional and simplified Chinese characters. But there are still some problems to work out. Experts have discussed what to do with characters that have several different meanings. This is particularly true of Chinese. Most experts doubt the change will have a major effect on how the Internet is used. “There will be some competition between companies to obtain popular words for addresses.” 26.
