How can I improve my communicate English skills?

I had the same problem with Danish, because they arrange their sentences differently in certain situations as well. From my experience, the best thing you can do is speak English with a native speaker and have them correct the things you say. Then repeat the correct sentence and try to apply that corrections to other sentences that seem similar. Also, read a ton of articles in English that pertain to things you want to be able to talk about and learn the syntax of how the language is written. However, if you want to learn how to speak a language properly, the BEST way to do that is to speak with a native in that language as often as possible while receiving feedback on your language skills. That way you can both hear it properly and correct the mistakes that you make at the same time.

Hope this helps!
