i’m just starting to learn English and hope for your help.
what is the best time to use in sentences:
1. (you/ finish)…. your homework yet?
2. how long (she/have)…..that car?
3. i (never/be)…sailing, what’s it like?
4.it was late. most of the shops(close)…..
p.s. please, explain why you used this or that time
