Answer

can we say that
Est-ce que vous connaissez Pierre? Oui, il est bon etudiant

normally nouns need "articles". but "il" can use without an article for giving an opinion about something mentioned.As you can see There is a noun in the sentence.I am curious about whether it is correct or not?

Answer

Hi Ozan, 
Yes, you can say both -
il est bon étudiant 
and 
c'est un bon étudiant
Bonne Continuation!

Answer

Because "mes livres" is plural. If we look at the translation of ce sont mes livres, we see that 'ce sont' means 'these are'. Because we are talking about more than one thing, were going to have to use a plural demonstrative pronoun.

For example

• this is my cat = c'est mon chat [singular object, singular pronoun]

•these are my cats = ce sont mes chats [plural objects, plural pronoun]

Hope this helps:)
