Comment:

> Listen to English audio files or English podcasts. You can listen to them while jogging, exercising, or any free time you have.

> Watch more English films. Maybe you can start by watching the films with subtitles of your language, so that you can understand it better. The next day, watch the same film, but without subtitles. Pay attention to the words and sentences more and evaluate yourself.

The more you do these exercises, the better your listening comprehension will be. ^__^

I have been trying various approaches, but they failed.
