'to be' modification

Hello.
I'm confused about the usage of 'to' or 'to be' to modify something.

I've known that... (although I don't know why one is correct and the other is not)
- Russian is a hard to master. (O)
- Russian is a hard to be mastered. (X)
- Russian is a language hard to master. (O)
- Russian is a language hard to be mastered. (X)
- That's a mistake easy to make. (O)
- That's a mistake easy to be made. (X)

However, I've also seen some sentences which looks similar but adapts a different rule like...
- The lesson to be learnt is that one should avoid making mistakes. (O)

At first, I thought the right upper sentence (the lesson to be learnt) is unnatural, although it seems gramatically right because of the very first examples(saying a language hard to be master is incorrect).
But the sentence is written by a native speaker so now I'm confused.

Would you explain this and teach when I can use 'to be' modification and when I cannot?

Thank you in advance.

Dear Langtraveler

Your difficulty is with the use of passive tenses. The basic construction which you are rephrasing in your sentences is :

it is + adjective + infinitive

e.g. it is easy to speak English
it is necessary to read this quickly
it is possible to learn Russian from a teacher

These constructions never take a passive infinitive e.g. to be spoke
