Hello and welcome to Apple Support Communities, yelyzaveta272.
If we understand your post correctly, when you use the Translate app on your iPhone you're seeing results in Russian when you want to only see Polish or English. We’d like to help.
To verify, what language is your iPhone currently set to? If you change the current language does this have any impact on the issue? You can do this using the steps here:
Change the language on your iPhone, iPad, or iPod touch
Also, you may want to review the steps in this article to make sure you're using Translate as expected:
