For example, I break a pot. Should I say I broke or I break to tell someone immediately? Another example is the word remember. Should I say I remember it or I remembered when someone mentions something?
- You say "I broke a pot" because, obviously, you just did it.
- You say "I remember it" or "I remember when someone mentioned something" because you still do but the action that the person did was done (mentioning something).
I would treat those verbs differently.
There is a specific moment in time when the pot breaks. That moment has been and gone.
I broke the pot a few seconds ago.
For an ongoing process I might use another form:
I am breaking up the clumps of flour with the spoon.
(There are many other forms of English verbs, which seem like present tense, for example
When I break rocks into gravel I make sure to wear protective glasses.
Memory is different. Five minutes ago I remembered where I put down my lost keys, but for a memory that is current in my mind it is most natural to say
I remember the words to the song.
Yes you can. But I don't recommand. It's overkilled.
I read many novels just tell the story in present tense.
