In 2009, what is the most popular English word in the website on the Internet? Maybe the answer is
"unfriend". Is that true? In fact, "unfriend" is often used on social networking (社交的) websites. It has
become so popular that Oxford University Press recently chose it as the 2009 word of the year.
     If you are a member of a social networking website such as QQ, My Space or Face book, you can
add a new friend be sending someone a friend request (请求). If you later fall out with that person, what
can you do? You can hit the "unfriend" button (操作框) and remove him or her from your friend list. That
means you won't talk, exchange information, or see each other's updates on the website any more.
     Experts at Oxford University Press look at how the words of the English language change from year to
year. They chose words that are popular and have important culture meanings.
     Christine Lindberg, editor for Oxford's dictionary program, said the word "unfriend" is popular now and
may stay popular for a long time. People understand its meaning in the online social networking context, and
also "accept" it as a modern verb. So it makes an interesting choice for the Word of the year.
     How to use the word? You can say "I decided to unfriend my roommate on Face book after we had a
fight" or "I unfriend Alice on My Space when she does something bad to me".
