Hi, I need a user group can read certain pages.

I do not know how to do it, Thank you

For selective reading rights, check out List of 40+ page specific user rights extensions and especially the warnings on each of these access control extension pages as MediaWiki is not designed for access control and there are bound to be some loopholes left.

As a starting point I will recommend to try out Extension:Lockdown.
