How to Practice Longer Collocations

English is not something you can work on overnight in this way, but many learners find their pronunciation such as the vowel sounds and the rhythm, they improve over time without them even realizing. My next piece of advice is to get lots of real listening practice. This is a very long process, but exposing yourself to natural speech will get you used to the sounds. And it's really gradual. You don't have to live in England by the way.
