     Q:

     I'd like to know about fluency. What can I do to feel better when I'm talking to other people? Do you have

some ways to learn it faster? Please help me!

                                                                                                                                  -Roberto in Brazil

     A:

     Roberto wants to know how to become more fluent in English, and this is something you want to be able

to do "fast".

     First, if you get to meet English speakers much, the important rule is to listen not just to native speakers of

English, but also to very good users of English. If you don't, then listen to the radio, TV or films in English.

     The next step is to notice what it is that speakers of English do, which makes them sound fluent. The first

trick (诀窍) is to probably have confidence. Some people think they might make mistakes. Don't worry about

that. Your listeners will usually try hard to understand you-a few grammar mistakes aren't going to worry them.

     What you do need to worry about is pronunciation, especially stress (重音). When you learn a new word

or expression, learn it with its stress. Notice how a native speaker says it or look it up in a dictionary.

     Another good thing that speakers of English do is to have a few tricks up their sleeves (袖子) for when they

need to give themselves thinking time. Sometimes they use "filler sounds" like er,um and so on.

     It is also useful to know how to bring other speakers into your conversation so that you keep them intereste

d-and this is often done by asking questions like "What do you think?" "How do you feel about this?" and so on. 

     So, to become a fluent speaker, you'll need to put into practice all these kinds of things. And there's the key:

practise, practise, practise.
