Apa salah jk,, we not have oil now,,
To form the negation in English, you need 2 words. You can't make the negation only with the word "not".
You need an auxiliary.
We use "do". So the negation in 2 words is "do not" or the contracted form "don't/doesn't"
We don't have oil.
why do not use 'are' after we?
Memiliki tidak diterima sebagai arti have.
Now accepted :)
Is "currently" with meaning "baru-baru ini" acceptable?
I think, It is not acceptable. You can use recently for "baru-baru ini"
What the different between now and currently
Almost the same. You can consider they are the same, but in some context, there is a slight meaning difference. Currently is the actual state of something, but "now" or "right now" it's this very minute.
'are not having' ??
Kenapa tidak pakai are?
Kalo pake now bisa ga?
