Quick and short answer: you cannot. However, if you're a good actor you can "speak" complete English sentences phonetically without understanding a single word -- do this if you're short on time. There was once an American singer named Dalena who sang Vietnamese songs with pitch perfect accent without being able to speak Vietnamese. You may want to consult with her. Good luck!

q u i c k l y i agree with R, watch a lot of TV, especially dramas. also, keep asking questions on this site.

That will depend how short is your "short time" :D I think there is no shortcut to learning a language but definitely there is a systematic way, which differs from person to person. I can share with you MY way, for your reference :) 1. Train your listening skill by listening to English songs while looking at the lyrics. 2. Train your pronounciation skill by singing out loud together with the singer. 3. Train your recognition skill by recording simple conversations and replay them repeatedly 4. Improve your vocabulary by keeping a little notebook of new words you can find in your everyday life AND find out their meaning. Then you write the meaning down and read it everyday. 1 or 2 words a day might be good for a start. Well, to master a language you need to do more than this, I think :) I guess this might help if you are talking about "short time". Hope my two cents' worth helps!

Immerse yourself in the language. Read English magazines, books, put English posters on your walls, watch English TV, listen to English music and radio productions. Believe you are a fluent English speaker and try the best you can...
