Why do we say I listen to music rather than I hear music, when both translate into Vietnamese the same way?
This comes up constantly, and the answer rests on something fundamental: the difference between passive and active hearing.
Hear: sound arrives whether you like it or not
Hear is passive. The sound reaches your ear without any intention on your part.
Picture yourself working at your desk. Outside there is traffic, there are people passing. Your ears take all of it in, not because you decided to, but because ears work and the sound is there. No choice was involved.
Listen to: you set aside time for it
Listen to is the opposite. This is deciding to spend time on something: choosing the track, pressing play, sitting down and attending to it, whether music, a podcast or a lecture.
So when I hear music means someone somewhere put music on and it reached you. When I listen to music means you chose it and you are attending to it.
The same act of hearing, but a completely different agent behind it.
Why this detail is worth keeping
It looks small, but it reflects how consistently English organises itself: a clear line between what you actively do and what simply happens to you.
Once you have that principle, you start noticing a whole series of pairs working on the same logic.
Get a few of these and your Task 2 writing and Speaking become noticeably more natural, because you have stopped translating word by word. This is not a trick. It is how the language genuinely works. Understand it once and you use it correctly from then on.
