The verb “chat” means to talk (to someone) in a friendly,informal（非正式的） way.Today there are many （ places ） on the Internet where you can chat.You can chat with people all over the world,in many languages and about many subjects or topics.These places are （ usually ） called “chatrooms”.Sometimes you need to register(注册) to enter a chatroom.This means that you need to provide a username and possibly your e-mail （address）.Your username does not have to be your （ real ）name.It can be any name you want.When you have your username,other people in the chatroom will call you by that name and （ nobody ）else can use it.
Chatting is a good way to （ practise ）your “informal” English.Messages in a chatroom are usually short sentences.Sometimes （ they ） are not even sentences,（ but ） just a few words that are not really correct grammatically but may be a typical way in which we （ speak ） in a quick conversation with friends.To save time,people often use abbreviations（缩写） like TTYL (talk to you later ) or IDK(I don’t know).So don’t go to a chatroom to practise “perfect” English.Go to a chatroom to practise casual（随便的） or informal English and find new （ friends）.You can even use a chatroom to help improve your typing skills if you want.
