I just take it as getting used to hearing French people speak. It's crazy how I try to listen to them speak, and a million words can escape my comprehension before I fully grasp the first sentence. If this is your problem, I've learned that the best way to train your brain to register French dialogue is to think in the language. When you read French, try to understand it in French rather than translate every word mentally. Carry out your daily actions in French, think "Qu'est-ce que je vais manger?" rather than "What am I going to eat?"
