I've done my homework at home.
We use the verb doesn't in present simple only .
He/she/it doesn't.... .
i don't thibk u got ie vladimir....the question is wherther the present perfect tense shud be used or not not the simple present tense itself...
- if we say i've done (....)= im still doing it till now..."was doing it n still doing it till the present moment".
-but if we say i did my (....)= im no longer doing it ----> a complete action in the past.
