So I searched before and found thread are related for my question:
Reference: ELL question on "How about going to the cinema tonight?"
But it hasn't solved my question. ( by the way is it correct sentence? if I meant that problem not solved in the past but still in the present.)
Well,
how about going to see her?
I can't find the tense and it pretty confused. because I know that,
wh- + an auxiliary verb + subject + main verb + ing => Present progressive.
I saw going
for me it looks related to present progressive, but why the formulation is pretty different? where can I find extra details about this questions style?
