Friends! Thank you for all the answers! I'll give the answers to your questions a little bit later.
Now I corresponding with Google support and have another QUESTION to you:
I write in robots.txt this string:
Is it means, that not only "../articles/first/?PAGEN_1_1" will be blocked, but URL "../articles/first?PAGEN_1_1" (without "/") will be blocked too?
Thank you all for your answers!
