Something like this can do: 

use warnings;
use strict;

while(<DATA>){
  chomp;
  print $_,substr ($_,0,2),$/;
}


__DATA__

NOTE:I updated the code, since I was testing on an old Perl version before now.
If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
