lxl331977: dear john, can you tell me some skills about how to express myself clearly in stage 3 ?becase sometimes i can not express fluently when the topics refer to deeply dicussion .additionally, my vocabulary is limited.how can i use some  relatively simple words to state more deeper thoughts. 

John: Actually, as long as you can understand the interviewer's question,
it's ok if you have a limited vocabulary--you can still do well in
Stage Three.

One of the most important things is to stay relaxed; don't freak
yourself out just because you feel that you're not as fluent as you
should be.  Stay calm, and express yourself as clearly as possible.

If you find yourself not knowing what to say, just say what you're
thinking.  For example, if you're thinking, "Gosh, this is really a
tough question", then tell the interviewer, "Gosh, this is really a
tough question!"  Talk it out!

Also, a great way to talk about the complex topics that come up in
stage three is by giving simple examples.  For example, if the
interview asks you about divorce in your country, you could give an
example of someone you know who's gotten divorced.
