Ok, now that you've had a chance to tune your ears to connected speech and the way that we use it in the past tense with did. I encourage you to pay attention to it in media, when you speak with your friends, with native speakers, when you watche Tv, movies, with music, and play around with it.
See if you can imitate natives, see if you can really try to emulate the rhythm and flow of the english language because it will really make your English much more flexible and feel a lot more natural.
