Hi, Yana, what is the level of your qualification and how long have you been in touch with the English language?
Firstly, you need to build your foundation which is grammar, and gradually you will grasp the spoken part.
Grammar in any language mostly has the same rules but often varies in some parts.
That part could be overcome by investing in the basics. That is called early steps toward understanding.
Knowledge is attainable once you remain motivated and committed to learning.
