Practice with a native speaker.

Watch English movies. You can grab some good phrases from them. And just keep practicing speaking.

i think for fluency u should have a lot of information on the topic. but even if u know a little bit, u should have the skill to exaggarate it so much that u've a given a lecture on it. keep on adding examples to your points.

and wat is ur view ?
