We use the Internet for many things: business, shopping, writing letters, talking to people, finding information and so on. In recent years, a new kind of English has grown on the Internet. There’s no real word for it yet, so we’ll call it e-talk. People don’t like typing too much. To save time, they turn phrases into a few letters (called acronyms). Acronyms are often used in chat rooms(聊天室). Some of them are:

BTW(by the way);  BRB(be right back);  LOL(laughing out loud);  IMO(in my opinion)

People also use many abbreviations. They are shortened forms of words. Some common abbreviations are:

info(information);   puter(computer);    pic(picture);     sec(second)

We ususally don’t see people when we communicate on the Internet, so people have new ways to show feelings. Most people use their keyboards to draw “feelings”, such as:

:-) (happy);     ;-)(joking);        :-((sad);       :-O(surprised)

These days, many forums(论坛)have picture feelings. For example:

(happy)              (sad)               (angry)               (cool)

There are even whole new words, like ”newbie’s” (someone who is new on a chat board or forum). When you write something bad about someone else, it’s called “flaming” the person.

It takes time for people to get used to e-talk. Also, different groups on the Net have their own special ways of communicating. Newbie’s sometimes have to ask other people what they mean. As the Internet grows, e-talk will continue to grow and change.
