Like a knee-jerk reaction

There comes a point in your learning process where you simply leave behind the phase in which you have to think to connect words together. As far as stock phrases go, that tends to happen early. So, even at a basic level, students learn to blurt out How are you? and Where do you live? without thinking about word order or auxiliaries. That is the very essence of fluency. You just know what to say and don't hesitate. So far so good.

At the advanced level, however, you should keep that up in every conversation. Whether you like it or not, most of the things you are going to say have been said before. You were born into a world that already had that huge set of conventions we call "the English language". For writers and poets, self-expression is a different story, but for you, students of English, conventions are an unavoidable stepping stone on your way to mastering the language. So practice combinations, idioms, collocations until they become inevitable. The should be like a visceral, irrational response. Soon you will realize that many expressions leap to mind and you'll have to stop so you can pick the sequence you like best.
