Could you please tell me why shall I get few corrections if I record some English articles?For these articles are too long to get corrected,or something else that stop other advanced languagers from telling apart the difference between mine works and native persons'?
Well, the first thing to keep in mind is that there are a lot of other members writing texts for correction as well. To your credit, I see that you've been helping other members, so keep that up and hopefully you'll get some help back.
On the other hand, this should be required reading for anyone worried about their essays going uncorrected:

Your English is not advanced enough to be mistaken for a native speaker's. But it's getting good! Well done.
I think the problem is that if you write a LONG piece... people simply do not have the time!
