Question

Lomov :"if you like,i will make you a present of them.(Narration change)

Answer 1

Lomov assured that if she likes, he (Lomov) will make her a present of the items she liked (them).

Here from Direct speech the sentence has been transformed into the indirect speech.

Lomov has promised about a gift so the word assured is used to convey his mental and articulation of expression.  

In both the sentence meaning and approach is kept unchanged.
