I’m sure you have heard (ahem - here, for example) that it is important to surround yourself with the English language as much as possible. Hopefully you are watching English language movies and television in your spare time to better help you understand, retain, and reproduce new language. I am confident this site will help:
Playphrase.me is a free, searchable website that lets you look up common English phrases. Use this site to see when and how these phrases are used. Be sure to repeat the phrases to improve your pronunciation skills.
