No re-entry permit? Hmm, I don't know.
I got my GreenCrad since 2008, During 2009-2012 I was outside of USA more than 2 years,But came back without by asking questions at Dec 2012.
What should I do with this problem if I intend to apply the naturalization later?

Were you or your spouse in the US military or working abroad for the US government?
If not, you should have had a reentry permit or SB-1 visa to return, which you didn't have. You should expect trouble during naturalization, even if you wait 5 years, because technically you already lost your permanent resident status. Others with similar long trips have run into problems at naturalization time. Either they will deny your naturalization and leave you alone, or they'll try to revoke your green card.
Is it because he/she was out of US for more than 1 year or 6 months?
